Effect of Potassium and zinc on nutrient uptake on pigeon pea (Cajanus cajan L. Millsp.)

Abstract

A field experiment was conducted at research farm, Department of soil science and Agricultural Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani University to study effect of application of varying levels of potassium and zinc on productivity, nutrient uptake and quality parameters of pigeon pea during 2017-2018. Highest uptake was recorded with combined application of 30 kg K2O + 15 kg ZnSO4 along with recommended dose of NPK fertilizers (RDF) and was at par with application of 15 kg K2O + 15 kg ZnSO4 along with RDF and at par with 45 kg K2O + 15 kg ZnSO4 with RDF.
