Effect of In situ Moisture Conservation Practices and Nitrogen Levels on Growth and Yield of Rabi Sorghum in Vertisols Under Rainfed Condition

J.A. Kiran, B.S. Lingaraju

Abstract


A field experiment was conducted at Main Agricultural Research Station, Dharwad to study the effect of in situ moisture conservation practices and nitrogen levels on growth and yield of rabi sorghum under rainfed condition. Among in situ moisture conservation practices, ridges and furrows and compartment bunding were found beneficial in conserving higher soil moisture and resulted in higher grain yield or rabi sorghum (15.78 q ha-1 and 14.96 q ha-1, respectively) compared to flat bed method of sowing (11.74 q ha-1). Among the levels of nitrogen to rabi sorghum, application of 75 kg N per ha recorded higher grain yield (15.12 q ha-1) over 25 kg N per ha (12.53 q ha-1) but was found on par with the present recommended dose of 50 kg N per ha (14.38 q ha-1).
