Influence of different organic sources of nutrients on yield attributes of summer green gram

Abstract

An experiment was conducted to examine influence of different organic sources of nutrients for organic summer green gram cultivation. A field experiment was conducted during summer season of the year 2020-21 on organic certified plot A-7 at Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand. Different sources of organic manures were tested using randomized block design with four replications. The application of T8 (50% N through vermicompost followed by seed treatment of Rhizobium) showed a significantly higher number of pods/plant and highest haulm yield (kg/ha) at harvest in green gram.A higher volume of seed index (3.23) and higher value of harvest index (42.44 g) were observed in treatment T10 (50% N through neem cake followed by Seed treatment of Rhizobium) at harvesting stage in green gram. The increase in photosynthetic activities of plant and root system enabled the plants to extract more water and nutrients from the soil depth, resulted in better growth and development of plants and ultimately led to higher yield.
