Seed Yield and Economic Returns in Coriander in Relation to Different Nutrient Combinations

Abstract

Organic manures along with the chemical fertilizers tend to reduce the total cost of cultivation and supplement the crop with the essential nutrients for growth and development of the plant. In view of this an experiment was conducted in coriander during winter season of 2012-13 at college of agriculture, Jabalpur, Madhya Pradesh to assess the effect of organic and inorganic sources of nutrient with different levels on various parameters of coriander. Results with regard to various levels of organic manures shows that poultry manure 5 t ha-1 produced the maximum number of umbels per plant (33.67), the maximum number of umbellets per umbel (7.06), maximum number of seeds per umbel (33.69), maximum weight of seeds per umbel (0.44g), maximum number of seeds per plant (603.75) and significant maximum seed yield per plant (6.09 g), seed yield per plot (1.85 kg) and seed yield per hectare (17.30 q). Results in relation to fertilizer levels shows that the maximum number of umbels per plant (33.46), maximum number of umbellets per umbel(7.04), maximum number of seeds per umbel (33.29), maximum weight of seeds per umbel (0.45 g), maximum seed yield per plant (6.01g), yield per plot (1.87kg) and seed yield per hectare (17.53 q) were recorded with 100% RDF. Results in relation to interaction effect of different treatments shows that, the significant maximum number of umbels per plant (36.27), maximum number of umbellets per umbel(7.71), maximum number of seeds per umbel (36.74), maximum weight of seeds per umbel (0.49 g), maximum number of seeds per plant (701.97) and the significant maximum seeds yield per plant (7.14g), seed yield per plot (2.04 kg) and seed yield hectare (19.16 q) were observed in poultry manure 5 t ha-1 + 100% RDF. The highest net return and cost benefit ratio 1: 2.98 with treatment combination T5 (Poultry manure 5 t ha-1 + 100% RDF).
