Abstract: A field experiment was conducted in All India Coordinated Research Project on Coconut (AICRP- palms, Sabour) under drip fertigation system. In order to generate information under long term (5 years) drip fertigation, with the following six treatment combinations viz. (i) control (T1), (ii) 25% of the recommended dose of NPK fertilizers (RDF) through drip system (T2), (iii) 50% RDF through drip, (iv) 75% RDF through drip, (v) 100% RDF through drip, and (vi) 100% RDF through soil application (T6) a dissertation work was taken in the Department of Soil Science and Agricultural Chemistry, Bihar Agricultural University, Sabour, Bihar. The experiment was carried out in randomized block design (RBD) with six treatments and replicated four. The soil of experimental plot was silty clay loam type in texture under low available in N, P and K with pH 7.3(check the initial value). Among all parameters like Available and total N, P and K were recorded higher with the application of treatment T5 - 100% of the RDF through drip system which was significantly superior over other treatment but was statistically at par with T4 at all depths of soil. The maximum P value was observed in T6 treatments which was at par with T5 treatment in surface soil (0-30 cm). Available micro nutrients content in soil recorded non-significant difference among the all treatments under drip fertigation study.
