Abstract

A field experiment was conducted for two years (2008-2009) in factorial randomized block design with three replications to study the effect of sources and levels of potassium on yield and quality of fig ( cv. Deanna) at National Agriculture Research Project. Ganeshkhind. Pune (M.S.). The treatments consisted three sources of K2O ie. muriate of potash , nitrate of potash, sulphate of potash. These sources were applied with four levels of K2O i. e. L1- 75% of recommended dose of K2O, L2 -100% of recommended dose of K2O , L3 - 125% of recommended dose of K2O and L4-150% of recommended dose of K2O.The data of two years revealed that among different sources application of K2SO4 as a source of K2O showed significant increase in yield quality and nutrient uptake over KCl application. The higher application of K2O showed positive effect on these parameters. The application of 150% of recommended dose of K2O to fig found significantly superior for yield, quality and nutrient uptake.
