Effect of organic manures on growth, yield and economics of coriander (Coriandrum sativum L.)

The experiments were conducted on effect of nutrient supplementation through organic manures on coriander at Horticultural Research Farm, Tirhut College of Agriculture, Dholi (RAU, Pusa) for 3 consecutive years (2009–2012). The treatments used were FYM 100% (10t ha−1), vermicompost (5t ha−1), FYM (50%) + vermicmopost (50%), FYM (25%) + vermicompost (75%), FYM (75%) + vermicompost (25%), RDF (50 N: 40P: 30kg ha−1), FYM (15t ha−1) + RDF (50N: 40P: 30K kg ha−1) and control. Results revealed that the treatment FYM (15 t ha−1) + RDF (50N: 40P: 30K kg ha−1) was the best in improving the growth attributes of coriander and increased the yield 105.26 per cent over control and gave the highest net return of Rs.68,370 (ha−1) with benefit-cost ratio of 2.67. The next effective treatment was RDF (50N: 40P: 30K kg ha−1), which improved the growth parameters and increased yield by 78.19 per cent over control and gave the highest net return (Rs.56,970 ha−1) and benefit-cost ratio (2.50).
