Abstract:
A field experiment was conducted at Agricultural Research farm, B.R.D.P.G College Deoria (UP) during the year 2019 and 2020 to study the response of rice to summer green manuring and soil characteristics. The soil was sandy loam typic Ustochrept (Inceptisols). Green gram (Phaseolus aureus Raxb) Sunnhemp (Crotalaria juncea Linn) and Dhaincha (Sesbania aculeata Poir.) were grown for summer green manure during May l to June. The summer green manuring alone and in combination with N fertilizer resulted in higher grain yield. The highest grain yield of rice was obtained through incorporation of Sunnhemp in combination with 120 kg N ha^-1 applied as urea followed by Dhaincha and Green gram. Increased due to green manuring along with 120 kg N ha. The physio-chemical properties of soil such as BD and pH decrease and EC, OC, CEC were enhanced due to incorporation of green manures and combined use of inorganic fertilizer.
