Abstract:
An experiment was carried out at the department of Seed Science and Technology (E-block) Eastern Dry Zone of College of Agriculture, UAS, GKVK, Bengaluru to find out the efficacy of different spacings and bio-inoculants treatment on cost benefit ratio of alfalfa (Medicago sativa L.) cv. RL-88 seed production. The results revealed that higher economic return to cost bear recorded higher in (30 x 10 cm) close spacing (1.92 and 2.59) over other combinations during kharif and rabi seasons respectively. Whereas the higher fertilizer dose in consortia with bio-consortia seed treatment 20:100:40 NPK kg ha^-1 + Pseudomonas fluorescens + FYM (1.73 and 2.45) over other combinations during kharif and rabi season. Whereas, among the interaction of closer spacing accompanying the 20:100:40 NPK kg ha^-1 + Pseudomonas fluorescens + FYM recorded (3.07 and 3.79) during kharif and rabi seasons respectively, over other treatments.
