EFFECT OF PHOSPHORUS AND BIO-FERTILIZERS ON NUTRIENT CONTENTS AND UPTAKE BY PIGEON PEA (Cajanus Cajan L.) AND RESIDUAL SOIL CONSTITUENTS
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 54
Abstract
A field experiment was conducted during rainy seasons of 2013 and 2014 at the Rajola Research Farm, Faculty of Agricultural Sciences, Mahatma Gandhi Chitrakoot Gramodaya VishwaVidyalaya, Chitrakoot – Satna, Madhya Pradesh, India to study the effect of phosphorus and bio-fertilizers on nutrient content and uptake by pigeon pea and residual soil constituent. The nutrient contents in grain and straw viz. N, P and K deviated almost significantly due to phosphorus levels and bio-fertilizers but not due to their interaction. The highest phosphorus level (90 kg/ha) and dual bio-fertilizers (Rhizobium +PSB) resulted in almost significantly higher N, P and K contents and their uptake of Pigeon pea (Cajanus cajan L.). The highest uptake of nutrients by pigeon pea producing a total biomass up to 68.68 q/ha with highest P90 level was 81.15 kg N, 16.01 kg P and 48.84 kg K/ha similarly under dual bio-fertilizers, the corresponding uptake values were 78.75 kg N, 15.18 kg P and 47.14 kg K/ha significantly up to 90 kg P2O5 /ha and dual bio-fertilizers. The findings suggest that due to heavy withdrawal of nutrients by pigeon pea variety UPAS-120, the succeeding crop must be nourished properly based on nutrients status of soil.
