Prof. Meena have three significant achievements exclusively during associate professor period:
First achievement a long-term experiment was initiated to evaluate the production potential, sustainability, resource-use efficiency and economics of nine pearl millet based cropping systems for the purpose continuous adoption of this pear millet-wheat system in the region with poor crop management practices results in loss of soil fertility due to multiple nutrient deficiencies at same root zone level. This decline in soil quality results in a decrease in factor productivity. Crop diversification has been recognized as an effective strategy for achieving the objectives of food security, nutrition security, income growth, poverty alleviation, and employment generation, judicious use of land and water resources, sustainable agricultural development and environmental improvement. Diversification of pearl millet-wheat based system to increase productivity per unit resource and fulfil basic needs for pulses, cereals, oilseeds and medicinal and regulating farm income, with standing weather aberrations, controlling price fluctuation, ensuring balanced food supply, conserving natural resources reducing the chemical fertilizer and pesticide loads ensuring environmental safety and creating employment opportunity. The study revealed that system productivity in terms of pearl millet equivalent yield (PMEY) was highest (30488 kg ha-1) with groundnut-wheat-cluster bean-onion crop rotation. Moreover, groundnut-wheat-cluster bean-onion recorded the highest SYI and land use efficiency (0.65 and 73.97%) followed by pearl millet-wheat-cluster bean-barley sequence (0.63 and 65.75%). The groundnut-wheat-cluster bean-onion also generated highest number of man days/ha/year (405).; Second achievement was IFS model approaches had significantly highest pearl millet equivalent yield of dairy component (15693 kg PEY) which shares 33.53 per cent followed by crops component (12742 kg PEY) with a share of 27.22 per cent of IFS model production. And third achievement during Kharif-2017 to Rabi- 2019-20 we produce B/S and TFL seed 1334 Qt and generate income Rs 1,35,60,980 (One crore thirty-five lac sixty thousand).
