Effect of varying levels of potassium and zinc on yield, yield attributes, quality of 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 seed and stover yield of pigeon pea was recorded with the combined application of 30 kg K2o + 15 kg Znso4 ha-1 along with recommended dose of NPK fertilizers (RDF) and was at par with application of RDF + 15 kg K2o +15 kg Znso4 ha-1, RDF + 45 kg K2o ha-1 + 15 kg Znso4ha-1 was significantly superior over RDF and other treatment. Higher levels of K and Zn along with RDF also recorded higher growth and yield attributes at harvest viz., protein content, test weight, straw and seed yield of pigeon pea.
