Response of black gram to graded levels of potassium on yield and yield components

Abstract

The investigation into the response of black gram to graded levels of potassium on the yield and quality characteristics (cv.BDU-1) were carried out on the well drained soil with PH 7.82, EC (0.286 dsm-1),organic carbon 5.3 g Kg -1 and CaCO3 53.40 g Kg -1. A uniform dose of 25 and 50 Kg N and P2O5ha-1 was used in all treatments. The varying levels of potash were 15,30,45 and 60 kg K 2O ha-1. The results revealed that application (RDF+ 60 kg K2O ha-1) showed a significant increase in yield and of black gram over control which is at par with the treatments (RDF+ 45 kg K2O ha-1) and (RDF+ 30 kg K2O ha-1).
