 ABSTRACT

A two year field experiment was used to evaluate the effects of integrated nitrogen management on growth, yield and economic of grain amaranth (Amaranthus hypochondriacus L.). The experiment was conducted at College Farm of N. M. College of Agriculture, Navsari Agricultural University, Navsari during rabi seasons of 2016-17 and 2017-18. There were six treatments applied to grain amaranth. Significantly higher plant height, leaf area index, chlorophyll content and straw yield were recorded under treatment T1 (100% RDN through inorganic fertilizer) and being at par with treatment T3 (75% RDN through chemical fertilizer + 25% through BC) and T2 (75% RDN through chemical fertilizer + 25% through FYM). Whereas, significantly higher spike length, no. of lateral spikelets/spike, test weight and grain yield with maximum net returns and B:C ratio were recorded under treatment of 75% RDN through chemical fertilizer + 25% through BC (T3) and which remained at par with application of 100% RDN through inorganic fertilizer (T1) and 75% RDN through chemical fertilizer + 25% through FYM (T2) in pooled analysis. Thus, integration of organic manure and inorganic fertilizer have higher yield potential and performed better as compared to inorganic fertilizer treatment as well as the treatment which receiving organic manure only.

Key words: Recommended dose of nitrogen (RDN), Leaf area index (LAI), Chlorophyll content, Grain yield, Straw yield, Economic
