Abstract:
Greengram occupied 34.4 lakh ha of area all over India with a production of 14 lakh tonnes and 406.98 kg/ha productivity. India is the largest producer and consumer of pulses in the world accounting for about 35 percent and 25 percent of world’s area and production respectively. It occupies a significant place in India for vegetarian people and are considered as rich source of protein. A field experiment was conducted to study climate resilient crop management practices for increasing production and productivity of green gram in rice fallow by application of hydrogel and nano solution at the instructional farm, Odisha University of Agriculture and Technology, Bhubaneswar during rabi 2018-19. The experiment was with sixteen treatments with combination of two cultivar such as Virat and IPM 02- 14 and eight combination of moisture saving elements along with control of environmental and improved practice. All the plants grown in T₈ (Plants grown with Improved practice, Hydrogel, Nano Solution and Trichoderma) with Virat variety produces maximum yield and required less water and its water use efficiency was also high. Due to treatment with hydrogel and nano solution the root proliferation occurs and number of root nodules was also increased and it provides maximum yield. As we known root always goes in search of water. So where we applied hydrogel water was available with in a short distance. For this reason the growth of plant is very good here. Height of the plants, number of branches, total number of leaves, number of leaves in main shoot, dry weight of shoot and root leaf, no. and weight of nodules are also high in the plants which are grown under T₈ treatment.
