Abstract
The present investigation was conducted during August, 2003 to November, 2003 at the Sub Research Station, Gaja, G.B. Pant University of Agriculture & Technology, Hill Campus, Ranichauri, Tehri Garhwal (Uttaranchal), to study the effect of spacing in green pod yield of vegetable pea cultivars. The experiment was laidout in a Factorial Randomized Block Design, having fifteen treatment combination with three replications. The plant spacing range was from 25x5 cm to 35x5 cm. During the course of investigation, plant emergence, plant height, number of primary branches, leaf area, fresh and dry weight of plant, root length, number and fresh weight of nodules per plant, number of pods per plant, pod length, green pod yield, total soluble solids, protein profile, linear correlation etc. were studied. Significant effect of spacing was observed on number of primary branches, leaf area at 45 DAS, fresh and dry weight of plant, number of nodules, green pods per plant, pod length and green pod yield. Except number of primary branches, leaf area, root length, TSS content, the varieties were differed significantly in respect of plant height, number of nodules, number of green pods/plant, pod shelling percentage and green pod yield. Among the five varieties selected for investigation, standard check „Arkel‟ was found the best with respect to pod length, number of pods per plant and green pod yield. In different spacing and varietal combinations, highest yield of green pods (79.80 q ha-1) was obtained in S1V5 („Arkel‟ was at planting distance of 25x5 cm). From economic point of view also, standard check „Arkel‟ had found to be the most profitable, having a net profit of Rs. 42,018.75/ha, under recommended package of practices followed by „Pusa Pragati‟. The B/C ratio was also same (2.33) in both the varieties. The total number of protein bands in the seed of five varieties during SDS-PAGE analysis were varied from 19 to 23. Based on the findings of the present investigation „Arkel‟ and „Pusa Pragati‟ are the most suitable varieties for the sowing in Rainy-Autumn season under the rainfed mid hill climatic conditions of Uttaranchal, it sown at a planting distance of 25x5 cm.
