ABSTRACT
A field experiment was conducted during 2013-14 at experimental farm of Department of Soil Science and Argil. Chemistry, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, Maharastra, to find out the effect of potassium and micronutrient on growth, productivity, profitability and quality of greengram under vertisol. The experiment was laid out in RBD replicated thrice with 8 different treatments of inorganic fertilizers and micronutrients. The maximum plant height and leaf area were obtained with treatment RDF + 50 kg K2O ha-1 + Grade II (0.5%) micronutrient in all the growth stages. The seed yield (kg ha-1) ,stover yield (kg ha-1) number of pods (per plant), number of nodules(per plant), fresh weight of nodules (per plant), biomass production (g plant-1),dry weight of roots, root length were at higher magnitude when green gram received RDF + 50 kg K2O ha-1 + Grade I micronutrient followed by application of RDF + 50 kg K2O ha-1 + Grade II foliar spray.The highest protein content (19.21%) and seed index (5.19) was recorded by application of RDF + 50 kg K2O ha-1 + Grade II (0.5%) micronutrient. GMR and NMR were maximum when greengram received RDF + 50 kg K2O ha-1 + Grade I micronutrient application. However, the C: B ratio was higher in treatment RDF + 25 kg K2O. Combined application of 20 kg N ha-1, 50 kg P2O5 ha-1 and 25 kg or 5O kg K2O ha-1 + Grade I micronutrient (10 kg ha-1) or Grade II foliar spray (0.5%) found superior over only N and P application in greengram which increased in respect of growth, productivity, profitability and quality.
Key words :
C:B ratio, Greengram, Growth & productivity, Micronutrients, Potassium, Yield & quality attributes.
