A Good Harvest Crop Management By Nathan Koskei & Erastus Matete Water Management Soils - To cultivate a healthy shamba, one must study the soil well. Soils hold varying amounts of water depending upon the percentage of silt, sand and organic matter. Soils with a greater amount of clay and silt have a finer texture and hence hold more water. Water is absorbed very slowly through clay soils, hence watering should be done less frequently. On the other hand, water seeps in very fast through sandy soils; therefore, organic content should be added to improve water holding capacity. Evaporation- Avoiding excessive evaporation is another important aspect of water management. Ideally, watering should be done in the morning or evening, as evaporation rate is at its highest in the afternoon. Watering should be avoided under windy conditions as strong winds increase the rate of evaporation too. Digging furrows around the plants helps in reducing water loss through evaporation. Irrigation - It is very important to decide what irrigation system to use depending on water availability and evaporation rate. There are many types of irrigation systems these include: micro-spray, sprinklers, drip systems, soaker hoses and furrows. Rainfall- Rain is an important factor that should be considered before implementing water management procedures. Watering should not be done before or after the rain to avoid overwatering and root rot in plants. Crop Protection Here we mainly dwell on pests and diseases and their management. In protecting a crop, a farmer may use chemical, biological, mechanical and cultural control methods. Pests and Diseases Management • • • • • Always scout for pests and diseases in the morning Control pests and diseases to ensure that they are kept in check and do not reach economic injury level Common crop pests include; Aphids, thrips, whiteflies, cutworms, bollworms, leaf miners, spider mites and nematodes. Common diseases include: Wilts, Blight, Rots, Leaf spots and Mildews. For the control of pests, cultural methods such as clean weeding, use of certified seed and destroying alternate hosts are best. • Carry out preventive spraying in accordance to weather conditions and chemical label. Do not wait till the pest or disease symptoms begin to show. • For diseases such as mildews and blight, copperbased or sulphur-based fungicides are used. It is very important to note the Active Ingredient (AI) so as to avoid doing one kind of spray every time. • Viral diseases such as the mosaics and leaf curls have no cure. When dealing with these viral diseases, vectors ought to be controlled because they are the key transmitters of these diseases. Key vectors include aphids, thrips, and whiteflies. Nutrient Management Nutrient management is critical because it varies depending on the stage of the plant, deficiency symptoms and the soil analysis results. • The plant should constantly be fed because it is continuously growing and producing. Top dress at the 3rd week with the appropriate fertilizers and repeat it after every 6 weeks. • Foliar feeds should only be used in cases where top dressing was delayed or where an urgent deficiency symptom is at hand.

The companies De Ruiter Seeds, Seminis, Royal Sluis, Petoseed and Asgrow Seeds, are merging into one unique integrated Monsanto Vegetable Seeds Division. To continue serving you better, we have adopted a global brand strategy and enhanced our packaging quality. We have done this by branding all our products as Seminis for outdoor varieties and De Ruiter for Indoor products for ease of identification. Therefore Royal Sluis and Peto seeds will disappear as product brands from September 2010 - the product portfolio will remain the same, only the brand and packaging will change. This means that what we used to sell under Royal Sluis or Peto seeds brand will be commercialized under the SEMINIS brand for open field varieties and DE RUITER SEEDS for protected varieties. Our ability to supply you with the highest quality varieties and hybrids which contribute to your success will thus be reinforced. The Royal Sluis or Peto seed branded products already in the pipeline will continue and only our supplies from the mentioned date will be in the new branded packaging. Please note that the products remain the same. >>> Monsanto Crop Developers in a field of Mercedes F1 >>> INSET: A Mercedes F1 bulb Same Quality Same varieties NEW NEW NEW N EW NEW N EW 2 OLDOLD Also, to ensure continued growth in farming in the region, we have introduced two new innovative products, Onion Mercedes F1 and Pepper Tycoon F1, which are currently available commercially. . . .continued from pg 1 • • • NPK are the major critical nutrients. P - Phosphorous is for root development, K - Potassium for fruit development and N - Nitrogen for the vegetative growth. Nutrient deficiency should not be confused for disease symptoms. It usually leads to physiological disorders. Avoid excessive Nitrogen; it leads to excess vegetative growth, poor fruit set, smaller fruits, hollow fruits and poor keeping quality. Weed Control Weeds are unwanted plants in gardens that compete with crops; they reduce available moisture, nutrients, sunlight and growing space needed by crop plants. Their presence can reduce crop growth, quality and yield. In addition, they can make harvest difficult. Weeds also serve as a host for diseases, insects and animals (rodents, snakes, etc.). Garden weeds are hard to control because they grow rapidly, produce vast numbers of seeds, and spread aggressively by vegetative structures and/or seeds. In a vegetable ‘shamba’, weeds should never be allowed to grow to a level that can cause economic injury. There are several methods that should be used in a combined, coordinated effort to control weeds. They include cultural methods such as crop rotation as well as mechanical and chemical methods (e.g. herbicides). Harvesting Most vegetables are harvested just before full maturity for maximum flavour and the most pleasant texture. The following are vegetable harvesting criteria for judging whether your crops are ready for picking: Tomatoes A tomato is ready for picking once it starts breaking colour. Tomatoes that are picked when showing any orange or red color will be superior. Onions Onions can be harvested at any stage. When the tops fall over they should be dug and dried until the skin starts to peel off, then stored in a net bag. Carrots Carrots can be hard to judge. The tops of the carrot will show at the soil line and you can gauge when the diameter looks right for your variety. If the diameter looks good, chances are the length is fine too. But you will need to pull one to be certain. Small carrots are the sweetest, but it’s best to leave them in the ground until you need them so they won’t dry out. Cabbage Heads are ready to harvest when they are firm and heavy. If left too long they will split. Split heads are edible, but difficult to deal with in the kitchen. Broccoli Harvest broccoli while the head is still tight. Once the buds begin to spread it will soon flower. MONSANTO News Out in the Field in Uganda By Nathan Koskei Our Uganda Field Days took place in May in Luweero and Mukono Districts. Monsanto Vegetable Seed had a demonstration plot to display its hybrid tomatoes which included Assila F1, Eden F1 and outdoor Anna F1. These products attracted farmers who were particularly drawn by the products’ high yield as well as their tolerance to Tomato Yellow Leaf Curl Virus (for Assila F1), verticilum wilt and fusarium wilts. The Tukole Bukozi Limited sales team was invited to sell Monsanto Vegetable Seeds over the desk. Farmers who had seen the crop were keen on acquiring the seed and this made for good sales. Though this was exclusively a tomato show, farmers expressed their wish to have other Monsanto varieties including Cabbages Blue Dynasty F1 and Victoria F1, Pepper Red Knight F1, and Squash Early Butternut F1 and Ambassador F1. (See PAGE 6 for more field-day pictures) Peas Harvest before the individual peas begin to touch inside the pods. They become starchy and tasteless if left for too long. Cucumber Harvest before the seeds inside swell. As we anticipate the short rains, we would like to thank you for your continued support. We value your business and wish to maintain a successful relationship moving forward. In the meantime, if you have any questions, please contact our offices. Kobus Burger UGANDA FIELD DAY 3 GROWERS Speak Kibwezi River Farm Discovers Early Butternut F1 E By Mr Maria Ndolo with Daniel Musyoka ver since they began growing it in 2004, you are always sure to find a thriving crop of Monsanto’s Early Butternut F1 squash at Kiboko River Farm. The farm is located along Mombasa road near Kiboko market. It grows a wide range of horticultural crops throughout the year. “Initially, we began by planting small areas under Early Butternut F1 on experimental basis as we were unsure of the market,” says the farm manager, Mr. Maria Ndolo. They wanted to find out whether the local market as well as consumers in Nairobi and Mombasa would take to the product, especially since they were used to the local pumpkin. “To our amazement the adoption was very fast and orders started flowing from the local community as well as from the major towns,” says Ndolo. Now, the farm plants one acre every month which ensures continuous cash flow throughout the year. And with increasing demand for the squash, they are planning on increasing this area to two acres every month. Asked why everybody prefers the Early Butternut hybrid as compared the local pumpkin or other varieties, he had this to say, “It’s a sweet and high-yielding variety - producing upto 27 tonnes per acre, it is also early maturing.” With these excellent qualities, Ndolo wonders why the farmers in the drier areas are not planting Early Butternut F1 which they will be sure of harvesting even with little rainfall, unlike the local pumpkin whose failure rate is very high due to the current unpredictable rainfall patterns. The manager’s humble request to Monsanto was not to think of withdrawing this variety from the market. “To our amazement the adoption was very fast and orders started flowing from the local community as well as from the major towns,” By Mr. Martin Swinchact with Daniel Musyoka “I have been growing this product for the last six years and it seems as though it has been improved on every time I grow it. This is what first comes to mind for Mr. Martin Swinchact when asked about the Red Knight F1 pepper. Mr Swinchact is the Chief Fund-raiser at Pendekezo Letu Children’s Home situated in Thika. “ I have been growing this product for the last six years and it seems as though it has been improved on every time I grow it” • • • Why grow it for all these years? Martin says the variety has all the qualities and attributes any serious farmer and red capsicum consumer would be looking for. He outlines them very freely as follows: • Very attractive green colour for the green market and very deep red shiny colour for the consumers who like that way, Has blocky shaped fruits which are uniform in size at maturity, The fruits are firm and hence very good shelf life, Fruits are quick to ripen – 10 days after maturity with uniform colour change, Early maturity of 70 days for green and 80 days for red, High yielding – upto 30 tonnes/acre under greenhouse. High production is because the plant has short internodes. Highly demanded in the market because of its sweet taste and aroma. The above mentioned excellent qualities leave one with no alternative but to grow Red Knight F1. 4 >>> Carol Wanjiku, Farm Manager at Pendekezo Letu Childrens’ Home By Mr Peter Olango with Sammy Okita I n Chulaimbo division in Kisumu district, farmers harvest as little as 2 bags of maize per acre; but Mr Peter Olango, a farmer in this area, harvested 8 bags of maize from the quarter acre of his farm planted with Monsanto’s DK8031 maize hybrid. “ I am able to store 5 bags of grain for It is now several planting my family and earn some income from seasons since he the sale of the remaining bags” discovered Monsanto’s hybrid maize seed and farming has never quite been the same for Mr. Olango who is full of praise for Monsanto’s DK8031. “I am able to store 5 bags of grain for my family and earn some income from the sale of the remaining bags.” Mr. Olango planted his DK8031 crop on 12th of March 2010 and by 28th May the crop had reached physiological maturity.In total, the crop took 3 months from planting to physiological maturity, which is characteristic of DK8031. It’s early maturity means farmers in the medium altitude zones with warm temperatures can plant and harvest two crops a year. I Recommend Red Knight F1 • • • Kisumu Farmer Beats Weather with DK8031 DK8031 is also known for its ability to withstand dry periods during its growth stages therefore guaranteeing farmers a yield. “In the past we have had farmers planting in the month of February with the early rainfalls only for the rains to subside leading to crop failures. Farmers often have to replant their fields leading to increased costs of production,” says Mr Olango. He observes that with DK8031, even in the worst weather conditions, farmers will always have a harvest. This is one of the features of DK8031 most valued by the farmers. >>> Peter Olango in his field of DK8031 Another attribute of DK8031, as can be seen from the crop on Mr Olango’s farm (see picture), is its very strong stalks which enable the crop to withstand strong winds, thus reducing crop losses that result from logging of the crop. realise Ksh 105,000 from the one acre. This income is only possible with good crop management practises. Mr Olango has made some of his own calculations on yield expectations from DK8031, and shares these with us: If the farmer is targeting the dry grain market and harvests the expected yield of 32 bags per acre with prevailing price of Ksh 1500 per 90kg bag then the farmer is likely to realise Ksh 48,000. From one acre of DK8031 a farmer can expect a plant population of 21,000 plants. Therefore, if a farmer is targeting the green maize market and sells 1 cob per plant at Ksh 5, he is likely to However, Mr Olango cautions farmers on the importance of harvesting in good time.“Harvest when the cobs are fully mature to avoid early infestation of weevils at farm level.” Additional Facts on DK8031 • • • It grows best in mid to low altitude zones of Kenya. It takes upto 3 months to reach physiological maturity in warm environments. It can be grown in both long and short rain seasons in areas with 2 seasons. 5 MERU ASK SHOW QUESTIONSd How can I blot out Purple Blotch ? What are the Conditions for development? Purple blotch requires three conditions for infection: 1. The disease is present in the field 2. Water is present to allow for spore germination and 3. Temperatures ranging between 13 – 34OC, with an optimum temperature of 25oC for growth. What is it? Purple blotch is a fungal infection that attacks onions, leeks and shallots. It causes onion leaves to become blighted and die prematurely. It is caused by Alternaria porri, a fungus closely related to Alternaria solani, which causes early blight on potatoes and tomatoes. onion bhajias The fungus causing “Purple Blotch” is a wound parasite; it usually affects leaves that have already been attacked by other infections or insects. What are the Symptoms? By Nashone Mukabane About 1-4 days after infection occurs, the symptoms become visible; they begin as small water-soaked brownish lesions that usually have a white centre.

Answere By Isaac Nzuka IMAGES: Howard F. Schwartz, Colorado State University, Bugwood.org LOITOKITOK FIELD DAY Your As the lesions enlarge, the edges of lesions turn reddish-brown to purple. With time, dark brown to black concentric rings form throughout the lesions. In moist weather, a dense purplish-black mold growth covers the diseased areas. If conditions remain favourable for disease development, lesions may affect the entire leaf or stem causing it to eventually collapse and die. During harvest or storage the fungus can enter through the neck of the buld via injuries sustained during harvest. If the fungus invades the bulb, the infected area is initially bright yellow but eventually turns a characteristic wine red colour. The purple blotch fungus overwinters in mycelium found in leaf debris. Spores are formed during humid nights and leaf wetness periods greater than 12 hours. As the morning dews dries, spores become airborne, they are then carried to susceptible onion plants by wind, rain and farm equipment. One to four days are needed for symptoms to develop after infection. Disease development is greatest during prolonged periods of leaf wetness. How can you control purple blotch? • • • • • A fungicide spray program utilizing wetness monitoring and a broad spectrum protective fungicide applied prior to infection can provide good protection. Keep moisture levels low by using surface rather than sprinkler irrigation, good field drainage Allow for good air circulation by ensuring correct plant spacing to reduce overcrowding and disease development. A rotation out of Allium (onion-related) to unrelated crops for several years can reduce disease as well. Harvest onions during dry weather and ensure that the tops are dry to prevent introduction into storage. 7 Farm+Plus Agrovet Meet our Who said good farming can’t be done at the coast? CLIENTS excellent arrangement and display of products and prides itself in good customer relations, one of the factors that has seen it grow to its present size. In the past, the shop distributed our vegetable seeds under the Regina Seeds banner and now continue to sell our products as Monsanto Vegetable Seeds. The change of brand names has not affected consumption of the seeds. Mrs. Mnjalla agrees with this, saying that though there may be a change in name, the quality is unchanged. “Farmers have no problem with the new branding once they are assured that the products are the same,” she says. Farm + Plus personnel (L-R) Claire Achieng, Beatice Chepkemoi and the M.D. Mrs. Asya Mnjalla. F arm+Plus Agrovet is in Mombasa City along Jomo Kenyatta Avenue and opposite the Coast Bus office. The business was started in the year 2000 at Kongowea Market before moving to its present location in 2006. “Who said good farming, cannot be done at the Coast?” Before she begun the business, Farm+Plus proprietor, Mrs. Asya Mnjalla had once asked herself this question and this later became the key motivation for her venture. As the name suggests, the main aim of the business was to add value to the farms and farmers in the coastal region. Farm+Plus has since grown and has a wide network covering Kwale, Shimbahills, Malindi, Kilifi, Tanzania, Zanzibar and serves over 37 stockists and most NGO’s (Non Governmental Organisations) at the coast. Currently the business is exploring new markets in Mpeketoni, Voi and Wudanyi. Farm+Plus is a major distributor of seeds, agro-chemicals, animal health products and fertilizers. The business boasts an In closing, Mrs Mnjalla says, “We are proud to be associated with Monsanto and its high quality products because you begun with us, stood by us as we grew and you are still with us – long live Monsanto.” EVENTS Event Venue Date Field Days Wambugu ATC July Marigat July Kirinyaga Technical Institute July Waruhiu ATC - Githunguri July KEPHIS, Samia, Busia district July Mabanga ATC July CGA - Nyamira July Kerio Valley - Kibendo/Anin August Mombasa ASK August Nane Nane show-Tanzania August Agricultural Shows The range of Monsanto products on sale here are Anna F1, Eden F1 and Onyx tomatoes; Squash Ambassador F1; Blue dynasty F1 and Oxylus F1 cabbage varieties; our sugar baby Melon; Yolo Wonder capsicum; Red Creole Onion, Cucumber Ashley and Early Butternut F1 squash.
