International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Conclusion The output of Mobile App The spread of mobile telephony is a significant opportunity for farmers, extension workers and other stakeholders to work together more effectively. The mobile app ‘Unreaped Yield Potentials of Major Rainfed Crops and Scope for Bridging Yield Gaps’ was developed indicates possible crop management for bridging yield gap. which can help the policy makers, researchers, extension workers.

International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad T5-05R-1330 PASM Induced Yield Variability in Soybean Crop at Akola conditions A.

Mali Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola -444 104 (Maharashtra) *tupearvind@rediffmail.com Drought of different magnitude is becoming a common phenomenon, which affects adversely on Indian agriculture. Available soil moisture is a very relevant indicator of drought, especially in rainfed region. Soil moisture-based indices could be calculated using a simple region wide soil moisture balance methodology which entails collecting some of the base line data related to soil properties, climatic parameters and crop growth pattern, basically, soil moisture balance calculates the amount of rainfall available to crops depending upon crop water requirement, climatic evaporation demand and soil water holding capacity. It is suggested that one of the soil moisture based indices viz., Percent Available Soil Moisture (PASM) is used. These indices may be calculated at weekly interval and averages over dominant crop growth stages such as vegetative, flowering and pod development. These indices should be combined with other indicators for the determination of drought. Methodology A field experiment was initiated on the research field of AICRP for Dryland Agriculture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra since 2010 to 2018. Experiment was conducted in a factorial randomized block design with four replications. The treatment under study were four dates of sowing times in deferent Meteorological weeks such as 26 th MW, 27 th MW, 28 th MW, 29 st MW and three cultivar such as JS-335, JS-9305, TAMS-98-21 was sown at a spacing of 45x5 cm. the gross plot size 5 x 4.5 m and net plot size was 3.6 x 4.6 m. All the recommended agronomic practices were adopted during the experimental period. The data on the occurrence of specific phenophagical stages of soybean observed during the experimental period in the three cultivars under different growing environment and soil moisture at different depth to assess the effect of soil moisture on different growth stages and final seed yield. Long term Crop - weather and moisture depletion pattern in soybean shown that the Percent Available Soil Moisture (PASM) should not go below 50 percent for normal crop growth. The results shows that relationship between PASM (%) and Soybean seed yield (Kg/ha) for the year 2008-2018. 709 | Page Emerging approaches (RS, AI, ML, Drones etc) for crop management &assessment
