Nitrogen and Phosphorus Efficiency on the Fruit Size and Yield of Capsicum

A field experiment was conducted to study the effects of nitrogen and phosphorus on the fruit size and yield of Capsicum . The treatments comprised 4 levels of N (0, 50, 100 & 150 kg ha -1 ) and 3 levels of P (0, 30 & 60 kg ha -1 ). Length and breadth of fruit and number of fruits per plant increased significantly with increasing nitrogen doses up to 100 kg N ha -1 . However, average weight of fruit content increased significantly up to 150 kg N ha -1 . On the other hand, average weight of fruit and yield increased significantly with increasing levels of P up to the treatment 30 kg P ha -1 , whereas length of fruit and number fruits per plant was increased significantly up to the 60 kg P ha -1 . Considering the combined effect of nitrogen and phosphorus, the maximum significant length of Capsicum , breadth of Capsicum , number of fruits per plant and, average weight of fruit as well as yield were found in the treatment combination of 150 kg N and 30 kg P ha -1 .
