Effect of Organic Nutrient Management on Growth and Yield Attributes of Different Varieties of Rice

Abstract

A field experiment was conducted during kharif season 2018 at the Research Farm of Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (MP) to evaluate the “Effect of organic nutrient management on growth and yield attributes of different varieties of rice”. The experiment was laid out in RBD involving twelve rice varieties in triplicate. A uniform dose of organic manures i.e. 1/3rd Nitrogen through each of farm yard manure, neem cake and vermicompost were applied to all the varieties. Results of the study revealed that Pusa Sugandha 3 has recorded significantly higher growth parameters viz., plant height (69.80 cm), number of tillers per hill (13.53) and dry matter production per hill (43.39 g) among all the varieties. Among yield attributes significantly higher number of effective tillers per hill (11.40), total number of grains per panicle (164.67), panicle length (25.33 cm), grain yield (3298 kg ha-1) and straw yield (5463 kg ha-1) were recorded under Pusa Sugandha 3 variety of rice. However Sahyadri and MTU 1010 reported the highest sterility percentage (17.62) and test weight (24.45 g) respectively.
