Abstract
The results of a fertilizer trial conducted since 1969 at the Regional Cashewnut Research Station.
Vengurla (Maharashtra), have shown that while nitrogen and phosphorus increased the tree volume and yield of nuts significantly, no response was observed to potash fertilization.
Response to nitrogen 125 kg/ha in presence of phosphorus (50 kg/ha) and potash (100 kg/ha) was observed.
However, the response to nitrogen was restricted to 75 kg/ha in the absence of phosphorus and potash.
Similarly the response to phosphorus was restricted to 25 kg/ha when lower levels of nitrogen (25 kg or 75 kg/ha) were applied.
Response to phosphorus increased when nitrogen level was also increased to its maximum and the N x P interaction was significant.
The main effects of nitrogen and phosphorus and their interaction on tree volume and yield were significant.
However, their response at higher levels were controlled by potash application.
