Effect of Irrigation and Fertility Levels on Summer Soybean

A field experiment entitled Effect of irrigation and fertility levels on growth, yield and quality of summer soybean [Glycine max (L.) Merrill] was carried out during summer season of 2021 at the Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh. Results indicated that irrigation scheduling at 1.0 IW/CPE ratio recorded significantly higher values of plant height (30, 60 DAS and at harvest), number of branches per plant and dry matter production. Similarly, irrigation scheduling at 1.0 IW/CPE ratio recorded significantly higher value of yield attributes, yield and quality components viz., number of pods per plant, seed yield (1764 kg/ha), stover yield (2274 kg/ha) and oil yield followed by 0.8 IW/CPE ratio. Irrigation at 1.0 IW/CPE ratio to increase the soil moisture content before irrigation and least water use efficiency over other.
