Effect of NPK Fertilizers, FYM and Vermicompost on Growth and Yield Attributes of Okra (Abelmoschus esculentus L.) var. Devika

Abstract

This chapter highlights the effects of NPK fertilizers, FYM and Vermicompost on growth and yield attributed of okra. A field experiment was conducted in the year 2022 during the Kharif season at research farm of Department of Soil Science and Agricultural Chemistry, Sam Higginbottom University of Agriculture, Technology and Sciences Prayagraj (Allahabad) 211007 U.P., India. The design applied for statistical analysis was carried out with randomized block design having three levels of NPK @ 0, 50 and 100% ha^-1, three levels of FYM @ 0, 50 and 100% ha^-1 and three levels of Vermicompost @ 0, 50 and 100% ha^-1 respectively. The soil experimental area was sandy loam in texture. The design was laid out in randomized block design with three levels of NPK (0, 50, & 100%), three levels of FYM and three levels of Vermicompost (0, 50, & 100%) respectively. The results obtained with treatment T₉-[120:60:50 Kg NPK + 25 t FYM + 6 t Vermicompost] showed highest  plant height, number of branches plant^-1, number of leaves plants^-1, number of fruits plant^-1, total fruit per plant. Among the treatments, Organic manures as well as its mixture with full NPK considerably increase in growth and total yield attributes of okra. In contrast to all other treatments, combination of NPK, FYM and Vermicompost at 100% each respectively gave the most significant impact on okra growth. The study revealed that the application of NPK FYM and Vermicompost in treatment was found best in increasing growth and yield of okra.
