abstract
An investigation in the field was carried out at Instructional Farm of Krishi Vigyan Kendra (OUAT), Baliapal, Balasore, Odisha. For two years, the experiment was steered i.e. Kharif and Rabi season of 2013-14 and 2014-15 to study the “Response of Hybrid Rice under SRI - Green gram Cropping System to Sources of Nutrition”. The 12-treatment RBD experiment was designed. Using the SRI approach, the hybrid rice variety Ajay was transplanted. Periodically, observations regarding the growth and yield parameters of both crops were documented and subjected to statistical analysis. The findings demonstrated a considerable impact on the development and yield of hybrid rice produced under SRI when both organic and inorganic sources of nitrogen were applied simultaneously. Due to the combined application of nutrients from organic and inorganic sources, growth parameters such as plant height, number of branches, dry matter accumulation, and number of nodules per plant exhibited substantial enhancement. Rabi green gram had a noteworthy residual effect with application of 75% N by chemical fertilizers and 25% N through vermicompost to previous kharif rice. This resulted in a significantly greater seed yield (959 kg ha^-1) and stover yield (2753 kg ha^-1).
