Abstract
As a result of climate change during the last decade, the rainfall pattern and distribution has been exhibited frequent erratic situation of sudden downpour or long dry spells entailing in to severe stress on soybean crop that results reduction in yield. Keeping the above facts, the act of in-situ rain water management strategies for minimizing risk of crop failure and stabilizing soybean production was felt. Under such circumstances, KVK Panna of Madhya Pradesh introduced modified ridge and furrow equipment to line sowing of soybean through front line demonstration at farmer’s field. These demonstrations brought out enhancement in yield of soybean as 22.5 q/ha over farmers practice 11.2 q/ha. The benefit cost ratio was recorded as 1:3.8 as compared to farmer’s practices 1:2.0. The ridge and furrow equipment save the soil moisture through increased infiltration rate of rain fall and reduced runoff that leads slow rate of soil erosion. The furrow which allows drainage of excess water in case of heavy precipitation, while serves as in situ moisture conservation during dry spells, thus mitigating the detrimental effects of excess and dry spell situation.
