Description |
A field experiment was conducted at Students farm, College of Agriculture, Rajendr.anagar during Rabi season 1988-89 to study ·the effect of naphthaleneacetic acid (NAA), gibberellic acid (GA) and triacontanol (TRIA) on growth, . flowering, pod setting and yield of greengram (Vigna radiata (L.)wilczek) cv.ML-267. Three concentrations each of NAA (10,20,40 ppm),GA(l0,20,40 ppm), TRIA (O.S,1,2 ppm) and the control were tested in a randomized block design. NAA, GA and TRIA increased vegetative growth viz., plant height, leaf number, leaf area, LAI and total plant phytomass. Among the treatments GA and NAA at 40 ppm and TRIA at 2ppm recorded maximum values. GA and NAA regulated the reproductive growth by decreasing the number of days to flowering and pod maturity. Application of .NAA followed by GA and TRIA reduced the flower drop by 58-70% and thus increased the pod setting. GA recorded significantly higher pod number and seed yields followed by TRIA and NAA. Among the treatments GA and NAA at 40 ppm and TRIA at 1 ppm was more efficient in increasing the pod number and seed yields. higher 40 ppm. Increased levels of NAA recorded significantly test weight followed by TRIA at 1 ppm and GA at Chlorophyll content and nitrate reductase activity increased with increase in the levels of GA followed by NAA. and TRIA. Nitrogen content in leaves and seeds increased with increased NAA, GA and TRIA levels. |
