https://agroinfokenya.com/site/2017/03/01/crop-nutrition-how-to-do-it/Question : I have followed your advice on several crops in the forum, I currently have diversified into capsicum (pilipili Hoho) farming targeting high yields as well as bigger fruits with a high shelf life, kindly advise on the fertilizer to use
In Capsicum production ,the yields are dependent on several factors mainly the variety and the Nutrition program used.to attain high yields, a farmer has to not only look at ensuring the fruits are of bigger size but ensure the harvesting period is prolonged. Majorly the first fruits will always be a return for your investment while the later fruits will be key in your realization of a good profit hence the need to have all the fruits quality parameters (shape,size,color and shelf life ) uniform from the onset of harvesting to the last harvest
The type of fertilizer applied and the stage(time) of application is key in ensuring that the elements are available ‘just in time’ for the plant uptake .better yields will be realized at a PH range of 5.5-6.8 hence important to ensure that the fertilizer used do not interfere with your soil PH to ensure sustainability of the farming. Sufficient supply of both the primary,
secondary and trace elements in the required quantities will ensure you have a good crop.
Uniformity of the fruit sizes as well as production across the farm will also be affected by the element distribution across the farm which can be enhanced by using compounded fertilizers that ensure equal distribution of the elements across the farm to each crop, the form of these elements in the fertilizer applied will also determine the availability of these elements to the plant thought the growing period e.g. Use of products with polyphosphates as the form of Phosphorus will give better results whereas products with Nitrates as the form of Nitrogen which give quick results.
Use of an NPK fertilizer rich in trace elements at transplanting or within seven days after transplanting(immediately after TAKE) gives the plant a vigorous kick start, Calcium requirements should then be taken care of at the first top dress within the 3rd_ 4th week,it is prudent to apply calcium at this stage when the cells are actively dividing to ensure the timely availability of calcium in the cells before maturity sets in as calcium is immobile in plants .at the onset of flowering and fruiting stage, application of an NPK with a high K as well as trace elements is advised
To ensure the harvesting period is prolonged, continued application of fertilizer in splits after every four harvests(4 weeks) is essential in ensuring the fruits sizes are not compromised
Rates of applcation:This is greatly guided by the fctors discusd earlier on on this forum,avalability of a soil test report will be good in guiding us to this but a basic application rate of 75kg pr acre is advised.split applications during harvesting is advised.
