Abstract: On an average Srikakulam district received 105mm rainfall in summer showers and pre-kharif rains. Most of the farmers in the Srikakulam district were not utilising the pre and early monsoon rains for sowing of any crop and kept the ploughed land fallow up July 3rd week in the areas suitable to transplanting of rice. This results into high weed menace due to intermittent rains and no coverage, further it causes depletion of nutrients, evaporation of water and soil erosion. To create awareness on utilisation of land and improvement of net sown area, an On Farm Trial(OFT) was conducted for three years i.e 2020-21 to 2022-23 with the treatments of T1: Pre kharif Greengram – kharif paddy- Rabi Blackgram,T2: Green manure – Paddy– Black gram and T3: Fallow-Paddy-Black gram (Farmer practice) in three locations in the district. Due to growing of green gram during Pre-Kharif prior to paddy given average yield of 598 kg/ha. Also it added manure to the soil which increased 14.07% in paddy yield (5983 kg/ha) and 13.65 % in black gram yield (673kg/ha). Average of three years results of OFT on assessment of rice based cropping system shows that the treatment 1(T1) pre kharif green gram –kharif paddy -rabi rice fallow black gram gave higher additional net income of Rs 39,355/ha with B.C ratio of 1:2.08 followed by treatment2 (T2) i.e Green manure-Paddy-black gram Rs20,459 with BC ratio of 1:2.02 when compared to treatment 3 (T3) Fallow-paddy-black gram gave BC ratio 1:1.79.
