摘要

A field experiment was conducted at Kerala Agricultural University, Cashew Research Station, Madakkathara to study the differential response of graft raised cashew to applied N at different levels of drip irrigation. The treatment involved three levels of drip irrigation (0.40 and 80 litres of water per tree per day and three levels of N (0.750 and 1500 g per tree per year) in a three year old cashew plantation for a period of two years. In rainfed trees, application of N @ 1500 g per tree per yearresulted in an yield of 0.77 kg per tree while trees applied with no N gave no yield. In irrigated trees @ 40 litres per tree per day), N application @ 1500 g per tree per year resulted in an yield increase of 54 per cent compared to rainfed trees. Butwhen the irrigation level was increased to 80 litres per tree per day the corresponding increase was 124 per cent. Under the agroclimatic conditions prevail in the central zone of Kerala, a N dose of 1500 g per tree per year is necessary both for rainfedas well as irrigated cashew (graft raised). A higher dose of N application (1500 g per tree per year) has to go along with a higher dose of irrigation (80 litres of water per tree per day through drip irrigation during summer months) for obtaining better results from cashew.
