abstract
The present investigation was carried out to study the effects of vermicompost and poultry manure on growth parameters, yield and yield attributes of okra during Kharif 2023 at Organic Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Bundelkhand University, Jhansi. The experiment was laid out in Randomized Block Design (RBD) 8 treatments comprising three replications each. Observations on Plant height (cm) [30, 60, DAS and at harvest] recorded that high application of organic nutrients might have improved the soil physical and chemical properties and leading to the adequate supply of nutrients to the plants which might have promoted the maximum vegetative growth while the minimum plant growth was due to non-availability of nutrients. Observations on Stem diameter (cm) revealed that the application of organic nutrients might have improved the soil physical and chemical properties and leading to the adequate supply of nutrients to the plants which might have promoted the maximum vegetative growth while the minimum plant growth was due to non-availability of nutrients. It was noticed that number of leaves and branches per plant increased with increasing plant height successively with the increasing levels of nutrient. Combination of organic nutrients also recorded maximum plant height and number of leaves and branches also which helped the plants in better photosynthesis to attain vigor. Observations on Days to first flowering (DAS), Days to 50% flowering (DAS), Days to first pod setting (DAS), Number pods per plant and Days to first pod picking (DAS) reported that Integration of organic nutrition favored vigorous growth and synthesized more these hormones in plants, which might have helped to the translocation as well as more quantity of available phosphorus through the xylem vessels and their accumulation in the auxiliary buds that would have favored the plant to enter reproductive phase. Observations on Average pod weight (g), Pod length, Average pod diameter (cm), Pod Yield per plant (kg/plant), Pod Yield per plot (kg/plot), Average Pod yield per hectare (t/ha), Seed index [1000-seed weight (g)] and Total soluble solid (0Brix) found that Organic nutrition plays an important role in improving productivity and quality of fruit. Doses of Organic nutrition increased the vigour of plants, assimilating area, size of fruit, thereby resulting into higher weight of fruit.
