Abstract

Due to the low content of organic matter, high content of coarse sand and clay very low reserves of the sandy soils micro elements are very small and rapidly depleting under irrigation conditions. To mitigate the negative impact that these soil deficient qualities have on soil plants were carried out research on the implications extraroot and radicular fertilization on yield of cowpea, specific plant sandy soils. The results obtained, highlight the role of foliar fertilization with Green Plant products, which are composed of NPK + microelements, in achieving production increases of 21-56%, compared to foliar unfertilized. The highest production of cowpea (2757 kg / ha) was recorded by foliar fertilization with Green Plant, which is composed N15P45K15 + 6 microelements on the N60P60K60 agrofond.
