Abstract

A field experiment was conducted during winter seasons of 2015–16 and 2016–17 study the effect of fertility levels on nutrient contents and uptake of field pea genotypes. The N, P, K, S nutrient contents in grain and straw deviated significantly due to different genotypes and fertility levels as well as their interactions. Pant Matar-4 as well as P60 S45 recorded significantly higher nutrient contents in grain and straw over the respective treatments. Amongst the genotypes, the uptake of these nutrients was found significantly higher in grain and straw of Pant Matar-4 over other genotypes. The uptake nutrients of in grain and straw was found significantly higher due to increasing fertility levels upto P60S45 over P0S0. The highest nutrients uptake by field pea, producing a total biomass upto 32.45 q/ha with highest fertility level (P60S45), was 128.63 kg N, 50.01 kg P, 53.3 kg K, 17.18 kg S/ha. The findings suggest that due to heavy withdrawal of nutrients by field pea genotypes, the succeeding crop must be nourished properly based on soil test values.
