Keywords:
Foliar nutrition, improved seed, integrated nutrient management, isabgol, seed yieldAbstract
Field studies were conducted to evaluate the significant varieties/ genotypes and fertilizer management practices for harvesting the higher seed yield of isabgol in Transitional Plain of Luni Basin of Rajasthan. The maximum seed yield of 14.31 q/ha was provided by variety RI 89 followed by RI 3025 and GI 2 with 14.10 and 13.67 q/ha, respectively. The application of FYM @ 10 t/ha and biofertilizers (PSB & Azotobactor) along with chemical fertilizers @ 30kg N + 25 kg P2O5/ha provided 32.92% increase in seed yield of isabgol over farmer’s practice. The use of improved seed with recommended seed rate of 5 kg/ha along with foliar spray of 1% soluble NPK at flowering stage also provided 27.35% increase in seed yield over farmer’s practice.
