With a very good onion crop in the ground.  We must now think of bringing the crop to market.We have already sent out notes on onion storage which some of you did not get.  So herewith notes for those of you who did not get the first edition.
1. Storage begins with reaping - before the rain and at the right time of day.  Rain on a reaped onion crop lying in the lands will greatly reduce the shelf life of bulbs and make it much more difficult to store the crop.  At the start of reaping, harvesting teams must be ready,
2. and tractors and trailers fully operational for a slick, fast moving operation.  
With late planted crops and impending rain some growers have resorted to spraying the crops with gramoxone.  This certainly dries off green leaves quickly and seals the necks, but

1/4The horticultural farming landscape is dynamic. During my visit in Midlands and Matebeleland Provinces, I saw that a lot of people are getting an interest in horticulture. The major limiting factor in Matebeleland is water, most boreholes are drying out quickly. We are hoping ImageImageImageImage

1/6 Charter Seeds/Starke Ayres Sweetcorn, ready for the future. The Starke Ayres sweetcorn breeding program was started in the early 1990's.It has grown from very humble beginnings to the success it is today! The world class varieties produced from the program ImageImageImageImage
2/6 quickly became popular with both local and international producers. The sweetcorn success story continues to the present day and is a long way from finished. Growers generally favour a strong plant with good disease resistance and a high yield potential. Supermarkets and

1/5 Transplanting seedlings. The farmer should bear in mind the following when transplanting seedlings. Firstly the seedlings must be transplanted and watered as soon as possible after it has been obtained from the nursery. Seedlings should be placed vertically into the ground
2/5 and not side ways.This is to avoid a condition known as "J rooting".This condition results in a J shaped root system that ultimately decreases yield up to 50% or more, the root doesn't develop well, when it survives it doesn't grow well The farmer should ensure that seedlings
3/5 are planted at the correct depth in a little hole that has been formed into the ground prior to planting. If the seedlings are forced into the ground without a hole being prepared for them to be inserted into, the root system will be compromised and the plant will experience

1/3 The season doesn't wait for everyone. As farmers you need to plan ahead, The summer season is around the corner, you need to prepare for your nursery now for crops like tomato star 9009, 9037,Trinity, make a booking in advance with reputable nurseries to avoid last minute
2/3 disappointment. If you want to plant an early tomato crop now it's the time to do that. The 5Ps are important i.e Proper Planning Prevents Poor Performance. I have seen a lot of farmers looking for ready to plant seedlings from the nurseries without making a booking.
3/3 Let's get organized and you need at least 5 weeks for seedlings to be ready. If you want to plant in August you need to do your seedlings now. #farming #horticulture @Charterseeds @CdeNMaswerasei @corporatefarmg1 @yoAgronomist @MukuvariKaroi @basera_john @JohnMuchenje4

1/8 Green bean production. Green beans are an important crop for both the fresh and processing markets. For the fresh market segment uniformity, quality and general appearance are among the most important factors. For the processing market harvestability, a concentrated fruit set
2/8 and recovery play the most important roles. Some of these traits can be obtained by variety selection but a lot still depends on management and good farming practice. To achieve the desired result from a bean crop some basic steps must be followed to ensure that best yield

1/3 That's what we want to see from all Horticultural farmers in Zimbabwe or Africa at large to be successful. Our goal as Agronomists is to impart knowledge to farmers. Nothing is impossible in farming as long you follow the correct Agronomic and technical advice. Yesterday I ImageImageImageImage
2/3 visited some farmers in Arcturus and Ruwa Mash East province who grew tomato star 9009 5000 and 20000 plants respectively from Charter Seeds. That's the formula of success our seed + our techniques, and with Charter Seeds you won't go wrong. As Zimbabwe farmers we can grow

1/8 Beware the thrips threat. The onion thrip, Thrips tabaci is considered to be the major insect pest of onions Bulb yield can be reduced up to 30% and the damage is compounded by if thrips infect the crop with Iris yellow spot virus, of which they are the main vector.
2/8 damage caused by thrips can also provide other pathogens with entry points. Thrips species have wide host ranges, feeding on both broadleaf and grass species. Thrips feed on the leaves of onion plants, causing white or silver lesions. High level infestations cause significant

1/4 Fruit cracks are very common, especially on normal round varieties. Cracking is a serious problem as cracked fruit are unmarketable. Cracking appears in one or two manners - radial cracks(radiating from the stem) and concentric cracks (usually on the shoulders).This ImageImage
2/4 physiological symptom is associated with rapid fruit development and as with BER, fluctuations in water availability to the plant. When dry weather is followed by high temperatures and heavy rains, ripening fruits become very susceptible to fruit cracking. The internal
3/4 expansion is faster than the expansion of the epidermis due to the sudden increase of water availability and subsequent uptake by the plant, which in turn leads to the skin splitting. Cracking can be reduced by avoiding heavy nitrogen applications and fluctuations in water

1/7 Tomato is known to be a warm season crop. It can survive some cold, but it is not tolerant of very low temperatures. A top class tomato crop requires a stable temperature range with minimums and maximums not being too far apart. Wide temperature variation often results in
2/7 poor fruit quality or reduced yields. The minimum temperature is around 10°C with the maximum being 34°C.Optimum temperature is between 26 and 29°C.For optimal development of the tomato plant, a relative humidity between 65 and 85% is required. Higher relative humidity levels
3/7 negatively influence pollen release and distribution on the stigma. High humidity also creates a favourable environment for the development of various foliar diseases. The incidence of blotchy ripening also increases at high humidity. Conversely, low relative humidity may

Attention to detail is key to success in horticulture. Our formula for success=@Charter Seeds/Starke Ayres seeds plus our techniques (ROADMAP).Look at this "Beast" Trinity crop (4000 plants)@3 weeks old in Southlea Park surbubs Harare grown by a well seasoned farmer Morris Shumba ImageImage
Hygiene in greenhouse is the number 1 priority. That's what we want to see from all of our farmers.We have the seed that gives the farmer very high yield potential and quality that will make a farmer the most prosperous. The hybrid variety is more pricey, but brings high ROI, it
gives you the potential to double the yield and it will give you what your customers are looking for. Trinity is bred to perform.

Let's develop farming as a business not as a hobby.This tomato crop (1800 plants of star 9009,39 days old)from Murehwa communal area. Let's get rid of the mindset that rural areas are for subsistence farming. Let's use communal lands to do intensive horticulture farming, the
market is there, you can't claim you're a farmer but you're failing to grow vegetables for your community. Agriculture is the future. This is what we want to see across the country. I'm challenging my fellow homeboys and girls in Njanja to do the same like what this Murehwa

Let's use horticulture to take Zimbabwe to the next level.10 fruits in each measurement taken.1770g is Star 9065 fruit,1702g is Star 9062 fruit, Star 9065 in front,Star 9062 by ladies.These two processing varieties were grown in Bulawayo, with this kind of farming we will retain ImageImageImage
our status as the bread basket of Southern Africa. Star 9062 is a small plant and also very prolific. It does well in adverse conditions with high brix and takes 75 to 80 days to maturity. It doesn't need trellising. Star 9065 can be grown without trellising, however it is highly
recommended to be trellised. These two determinate varieties have good shelf life and deep effective root system.
