Abstract:
A field experiment was conducted at students’ Instructional Farm, Department if Agronomy. Chandra Shekhar Azad University of Agriculture and Technology Kanpur (U.P) in summer season for two consecutive years (2019 and 2020). The objective to study the response of selected greengram varieties under different crop geometry. Split plot design was adopted with three replications. The main plot treatments were three varieties (PDM 139, IPM 205-07 and IPM 99-125) and sub plot were three crop geometry (15 x 10 cm, 22.5 x 10 cm and 30 x 10 cm). Result revealed that greater plant height was obtained from varieties IPM 99-125 whereas compare to variety of IPM 205-07 and variety PDM 139. And also Variety IPM 99-125 produced significantly higher growth number of branches plant^-1, leaf area index, and fresh and dry matter accumulation. However, variety IPM 205-07 was obtained maximum yield attributes viz., pod length, number of seed pod-1, seed weight plant^-1, number of pod plnat^-1 and test weight and also it was found minimum days to flower initiation, days to 50% flowering and days to pod initiation. This might be due to variety characters and environmental factor. Crop geometry 30 x 10 cm was obtained maximum growth parameter viz., plant height, number of branches plant^-1, leaf area index, fresh and dry matter accumulation and it was also noticed that earlier days to flowering, days to 50 % flowering and days to pod initiation and was followed crop geometry 22.5 x 10 cm. Significantly higher yield attributed viz. number of pod plant^-1, pod length, number of seed plsnt^-1, seed weight plant-1 , and test weight were recorded with crop geometry 22.5 x 10 cm and was followed by crop geometry 30 x 10 cm and significantly lowest with crop geometry 15 x 10 cm. Variety IPM 205-07 was performed better yield attributes higher seed yield and protein content in grain over the variety IPM 99-125. Variety 205-07 significantly higher nitrogen, phosphorous and potassium uptake by plant was observed during summer greengram.
