Role of Pulse Sprouts Extract Foliar Spray in Seed Yield of Paddy Cultivars

To evaluate the performance pulse sprout extract foliar spray, SRI method of cultivation and their interaction effect on seed yield attributes in different rice cultivars, the field experiment was conducted with split split plot design. The experiment consisted of planting method as main plot treatment [SRI (P1) with 25x25 cm spacing and Conventional (P2) with 25 x 15 cm spacing]; short duration cultivars as sub plot treatment [ADT 43 (V1), ADT 47 (V2) and IR 50 (V3)] and foliar spray as sub sub plot treatment [Pulse sprout extract (2% cowpea) spray (T1) and Micronutrients mixture spray (Zinc, Iron, Boron) (T2)]. The results revealed that all the cultivars performed better under SRI method (P1) of planting and registered maximum growth, physiological and yield attributes such as number of tillers per hill, number of leaves per hill, leaf length and breadth, dry matter production per hill, leaf area index, number of productive tillers per hill, panicle length, single ear head weight, number of seeds per panicle and 21.66 per cent increase in seed yield over the conventional method of planting. Among the foliar spray treatments, the pulse sprout extract (T1) registered 21.88 per cent increase in seed yield over foliar spray of micronutrients mixture (T2). Hence, the SRI method of planting and foliar spray of pulse sprout (2% cowpea) extract (T1) can be recommended for seed production of paddy short duration cultivars.

Paddy seed yield was analyzed in SRI and conventional method of planting along with foliar spray of nutrients.

SRI performed better than t conventional method.

As a new attempt foliar spray of 2% cowpeaextract (T1) was compared with micronutrients spray (T2).

T1 increased 21.88 per centseed yield.
