Influence of potassium and zinc application on quality and micro nutrient uptake of red gram under Vertisol

Author(s): SS Thamake, MA Ajabe, SP Kale
Abstract: A field experiment was conducted during Kharif season 2016-17 to studies on effect of graded levels of potassium and zinc on growth, yield, nutrient uptake and quality of pigeon pea at experimental farm, Department of Soil Science and Agricultural Chemistry, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The experiment was laid out on Vertisols with eight treatments replicated three times in randomized block design. The initial soil fertility status showed that soils were slightly alkaline in soil reaction, safe in soluble salt, low in organic carbon content and calcareous in nature. The highest test weight and seed protein content was recorded by application of 30 kg potassium with 15 kg zinc along with RDF. The K application shows synergistic effects on other nutrients (Fe, Zn, Cu, Mn) uptake. Soil fertility was found to be improved due to application of potassium and zinc to pigeon pea.
