The experiment was laid out in randomized complete block design (RBD) with three replications under two farming conditions (conventional and natural farming conditions) utilizing seven lines viz., APL-55, APL-69, APL-80, APL-64, APL-84, Line 1-2-SPS5, Line 1-2-SPS11, along with four checks namely, Azad Pea-1, Lincoln, Punjab-89 and Palam Priya. Data was recorded on yield and related horticultural traits including powdery mildew incidence. Experimental findings revealed that higher yield was recorded under conventional farming condition in comparison to the natural farming condition. Under conventional farming conditions, Line 1-2SPS5 gave significantly highest yield (211.50 q/ha) followed by Line 1-2SPS11 (206.00 q/ha). In natural farming condition higher pod yield was noted in Line 1-2SPS5 (78.00 q/ha) followed by Line 1-2SPS11 (72.33 q/ha). Line 1-2-SPS5 exhibited resistance to powdery mildew disease and was also superior with respect to yield contributing traits like pod length, number of seeds/pod, number of pods/plant, pod yield/plant(g) and pod yield (q/ha) under both conventional and natural farming conditions.ennullThesis
