Abstract With the unparallel growth in area and production, soybean has established itself as a leading oilseed crop of India. The crop is mainly grown under rainfed conditions, and the distribution of rainfall plays an important role in yield realization. The changed landform management with broad-bed furrow (BBF) seed drill is gaining popularity as the system helps in in situ moisture conservation and draining out excess rainwater. The economic benefits of the BBF seed drill for the sowing of soybean were assessed using an economic surplus model for the period 2009–2010 to 2024–2025. The yield advantage from the adoption of BBF for the sowing of soybean and improved crop production practices was worked out to be 7.5% over the improved practices with flat-bed sowing and 22.2% over farmers’ practice. The results of analysis revealed that total benefits from the adoption of BBF for the period 2009–2010 to 2024–2025 have been estimated at ` 1351.93 lakhs at a discount rate of 5.2% and ` 838.74 lakhs at a discount rate of 8% or ` 84.50 and ` 52.42 lakhs per annum, respectively, with an internal rate of return of 59%. The demonstration of the potential to enhance productivity and farm incomes is an important step in promoting wider adoption of technologies.

Introduction Soybean is one of the major oilseed crops of India covering an area of 11.18 million hectares with a production of 13.16 million tons in the year 2016–2017 [5]. Madhya Pradesh, Maharashtra and Rajasthan states together contribute to about 90% of the area and production of soybean in the country. The crop is mainly grown in Central India on Vertisols and associated soils [2], and the region receives annual average rainfall ranging from 750 to 1300 mm mostly during the monsoon season [20], which exceeds the average evapotranspiration of 650 mm for this period. Soybean is cultivated mainly under rainfed conditions, and the amount and spread of rainfall during sowing & Purushottam Sharma [email protected] 1

and different crop growth stages pose a problem to the growers. Extreme variability in the duration, time and quantity of rains exposes the soybean crop to soil moisture deficit as well as excess moisture since either delayed monsoon, longer dry spells or early withdrawal of monsoon has been identified as one of the major constraints for poor performance of the soybean crop [7, 22]. Heavy rainfall immediately after sowing greatly affects the germination of the crop, whereas long dry spell during different crop growth stages induces water stress and in turn affects productivity realization by the farmers. Lower yields and high yield risk due to unce
