Effect of the Vermicompost and Poultry Manure on Groundnut (Arachis hypogaea L.) under Rain-fed Condition

Background: Use of organic manures to meet the nutrient requirement of the crop would be an inevitable practice for sustainable agriculture. Since organic manures generally improve the physical, chemical and biological properties along with conserving soil moisture and thus resulting in enhanced crop productivity along with maintaining the quality of crop production. Organic farming in recent years is gaining significance due to the realization of inherent advantages it confers in sustaining crop production and also in maintaining dynamic soil nutrient status and safe environment. Organic farming is also concerns to produce the quality food and human health, so that this research and studied the interaction effect of vermicompost and poultry manure on groundnut crop in Chitrakoot condition. Methods: The experiment was conducted at Rajola Farm of the Faculty of Agricultural Sciences, Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot in kharif 2019. The present experiment was conducted to evaluate the effect of different levels of poultry manure and vermicompost applications. The morphological and biochemical parameters were evaluated in experimental farm and departmental laboratory. Result: The combination dose of V3P3 (6 ton ha-1 vermicompost and 4 ton ha-1 poultry manure) was found to be best giving the maximum values. The effect of V3 on the number of pod per plant and number of seed per plant was maximum 15.20 and 3.22 and effect of P3 on the number of pod per plant and number of seed per plant was maximum 14.156 and 3.11 respectively. The interaction of vermicompost and poultry manure of the V3P3 combination was recorded maximum 17.13 per plant. Seed per pod interaction of vermicompost and poultry manure of the V3P3 combination also recorded maximum 3.66 per pod. Effect of vermicompost and poultry manure on 100 kernel weight was maximum in V3 (42.55 g) and P3 (41.00 g) respectively. The shelling percentage also was recorded maximum in V3 (69.77) and P3 (67.77) and interaction of both parameters was recorded non significance. Effect on yield (q/ha) was recorded maximum in V3 (1.05) and P3 (0.99) and the interaction was recorded maximum in V3P3 combination (1.27). The effect of vermicompost on oil percentage, protein percentage and oil yield (kg/ha) was recorded maximum 48.46, 21.33 and 1573.5 in V3 respectively. The effect of poultry manure recorded maximum in P3 (48.03), 20.68 and 1411.2 kg/ha oil percentage, protein percentage and oil yield respectively. The interaction of vermicompost and poultry manure was recorded maximum with the combination of V3P3 and found 49.52 oil percentage, 21.76 protein percentage and 1696.00 kg/ha oil yield. The results indicated that all these parameters were significantly increased due to vermicompost and poultry manure application. Their interaction was also significant. It was evident that a combination dose of V3P3 (6 ton ha-1 vermicompost and 4 ton ha-1 poultry manure) was found to be best giving the maximum values.
