Effect of Inorganic, Organic Nutrient Sources and Bio-Fertilizers on Growth Attributes, Biomass at Flowering and Nodule Weight of Phaseolus vulgaris (Rajma)

Abstract

It is essential to adopt new techniques and management practices as integrated nutrient management. The combined use of organic, inorganic manures and bio-fertilizer not only increases the crop yield but also improves the physical, Chemical and biological properties of soil. As enhance these properties, we can enhance the growth rate at flowering and nodule weight of plant, Phaseolus vulgaris. It did positive impact on quality and yield of Rajama. To study this, nine treatments, three replications, RBD design and Dibbling sowing method was adopted. The growth and yield attributes i.e. height, number of branches plant-1, Number of pods plant-1, number of grains pod-1 were recorded highest when only inorganic fertilizers @ 150% RDF was applied and these plant characters were recorded lowest when only vermicompost was applied.  Biomass production at flowering, grain and straw yield were highest due to application of 150% RDF of NPK through inorganic fertilizers.  The lowest biomass production at flowering was recorded where 2.5 t vermicompost at sowing and 50 % N through urea at flowering were applied. The lowest grain yield and straw yield was recorded when only vermicompost @ 5 tonnes ha-1 was applied.  Fresh weights of nodules were negligible.
