Influence of Sowing Methods and Sowing Time on Growth, Growth Attributes and Yield of Black Gram Vigna mungo L. under Rice Oryza sativa L. Fallow Black Gram Cropping System

Aim: Blackgram is one of the most important pulse crops raised in several types of soil under well drained conditions. Currently, it is cultivated as monocrop , intercrop as well as rice fallow crop in southern India. When the rice fallow pulse systems are described as, the pulse crop is seeded before or after rice harvest without ploughing, the remaining soil moisture may be better used through conservation agriculture measures. It's also known as a relay crop, a no-till crop, or a residual crop.In general, the production and productivity of black gram is declining because of poor management practices . Thus, this study was undertaken rice establishment methods as a strategy to determine the availability of residual moisture on the establishment of rice fallow black gram system during the early growth stages.

Place and Duration of Study: A field investigation was carried out at Agricultural College and Research Institute, Madurai (Tamil Nadu Agricultural University9o54’ N Latitude, 78o54’ E Longitude with an altitude of 147 m above MSL), Tamil Nadu, India from September 2019 to April 2020

Methodology: To see how different seeding methods and time influence the rice fallow black gram, the factors include rice planting methods as the main plot, methods of sowing black gram on rice fallow black gram as sub plot, and time of sowing black gram on rice fallow black gram given out in sub-sub plot treatment.

Results: The treatments had the best growth qualities, growth analysis, and yield. It could be because the above-mentioned combinations had higher residual moisture content, which resulted in a higher germination percentage, better crop stand, and higher growth and yield of rice fallow black gram.

Conclusion: The best management strategy is to sowing black gram in rice fallow situations with a rice fallow pulse planter at 10 days before rice harvest, under the direct seeded of rice establishment technique with drum seeder.
