Effect of plant growth substances and antioxidants on growth, flowering, yield and economics of garden pea, Pisum sativum L cv Bonneville

A field study was conducted at Horticulture Instructional Farm, CP College of Agriculture, SD Agricultural University, Sardarkrushinagar, Gujarat to find out the effect of plant growth substances and antioxidants on growth, flowering, yield and economics of garden pea, Pisum sativum L cv Bonneville. Plants were sprayed with treatments viz control, NAA (25 and 50 ppm), GA3 (50 and 100 ppm), 2,4-D (5 and 10 ppm), acetyl salicylic acid (100 ppm and 200 ppm), ascorbic acid (100 and 200 ppm) 30 days after sowing. The results revealed that the plant growth substance GA3 (100 ppm) showed highest growth parameters. Days to first flowering ranged between 48.97 and 52.75. The minimum days (48.97) to first flowering were taken by the treatment  GA3 (100 ppm) and all other treatments were statistically at par for the days taken to first flowering. The data on number of days taken for first and last picking after sowing and number of pickings were found non-significant among different treatments. The maximum yield (114.01 q/ha), net income of Rs 177642/ha and highest B:C ratio (4.52:1) were obtained in treatment  2,4-D (5 ppm).
