Abstract :
The experiment consisted of 9 treatments viz., T0 (DBW -17), T1 (Raj 3077), T2 (HD 2967), T3 (Lok-1), T4 (Raj 1482), T5 (Raj 4120), T6 (K-65) T7 (HD 2967), T8 (PBW-343) laid out in Randomized Block Design with three replications. The study showed that Lok-1variety gave highest grain yield (2.76t ha-1), harvest index (31.15%), highest net income (Rs. 110,000.7 ha-1) and benefit: cost (3.74) then the rest of the varieties. The plant height was found to be the highest under the treatment T3 (Lok-1) at 30, 60 and 90DAS the differences were statistically significant. Treatment T1 (Raj 3077) recorded significantly higher number of effective tillers per meter square than all the other treatments, while the lowest number of effective tillers per meter square was recorded for the treatment T3 (Lok-1). The spike length was recorded to be highest under the treatment T3 (Lok-1) which was significantly higher than all these other treatments, while the lowest spike length was recorded under the treatment T5 (Raj 4120). Number of grains spike-1 was recorded to be highest under the treatment T6 (K-65), while the lowest grains spike-1 was recorded under the treatment T0 (DBW-17). Treatment T2 (HD2967) recorded significantly higher test weight than all the other treatments, while the lowest test weight was recorded under the treatment T8 (PBW-343). The highest grain yield was recorded under the treatment T3 (Lok-1), while the lowest grain yield was recorded in treatment T0 (DBW–343) and the differences were statistically non-significant.
