Abstract
To protect the soil and minimize uses of chemical fertilizers, a research work was conducted at Agriculture Research Farm, CoA, BUAT, Banda during Kharif, 2019 to study the comparative effect of different combinations of organic manures on soil properties and productivity of sesame (Sesamum indicum L.). Experiment was laid out with 10 treatments in Randomized Block Design replicated thrice. The results indicated that the application of Vermicompost @ 2 t/ha + Farmyard manure @ 2 t/ha + Jeevamrut @ 500 l/ha (T10) recorded highest organic carbon content (0.44 %) in soil. In the treatment T4, application of RDF (40: 20: 20) + Vermicompost @ 4 t/ha significantly increase the available N 19.1 % over its initial value (201.0 kg/ha), available P 23.5 % over its initial value (17.0 kg/ha) and exchangeable K 21.32 % over its initial value (198.8 kg/ha). Micronutrient i.e. Fe (8.406 ppm), Mn (1.414 ppm), Cu (0.285 ppm) and Zn (1.097 ppm) were found highest in treatment T9 [Farmyard manure @ 4 t/ha]. Maximum plant height (49.57cm at 30 DAS and 147.72 cm at 60 DAS), seed yield (8.98 q/ha) and Stover yield (34.30 q/ha) were observed in treatment T4 [RDF (40: 20: 20) + Vermicompost @ 4 t/ha]. Number of capsules/plant (32.80) and Number of seeds/capsule (61.55) was observed maximum in treatment T5 [RDF (40: 20: 20) + Farmyard manure @ 4 t/ha]. Test weight (2.95 g) observed maximum in treatment T7 (Vermicompost @ 4 t/ha). The cost of cultivation was found highest in the treatment T4 (26010 Rs/ha) and Net return was highest in treatment T5 (38409.5 Rs/ha). The Benefit: Cost ratio was highest in treatment T1 (3.29) [RDF (40: 20: 20)] followed by treatment T3 (3.16) [RDF (40: 20: 20) + Farmyard manure @ 2 t/ha]. Overall, application of RDF (40: 20: 20) + Vermicompost @ 4 t/ha found suitable for the sesame crop in term of improvement in soil fertility and productivity of crop. However, it has to suggest for validating the recommendation in long-term study under different ecologies.
