Morpho-physiological characters, yield attributes and yield of mungbean as affected by different concentrations of Miyobi application
Abstract
A field experiment was conducted at the Field Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, during the period from March to May, 2012 with an aim to study the morpho-physiological characters, yield and yield attributes of mungbean as affected by different concentrations of Miyobi application. The experiment comprised five levels of Miyobi viz. 0 (control), 3, 4, 5 and 6 mg L-1 sprayed on mungbean plants at 30 days after sowing. BINA moog-6 was used as planting material and the experiment was laid out in a Randomized Complete Block Design. Results revealed that application of Miyobi increased plant height, branch number, leaf area, leaf area index, total dry matter, absolute growth rate and yield contributing characters over control. The highest branch number, leaf area, leaf area index, TDM, AGR and yield contributing characters were recorded in 5 mgL-1 Miyobi applied plant while the highest plant was observed in 6 mg L-1. Control showed the lowest of the above studied parameters. The highest seed yield was recorded in 5 mgL-1 Miyobi applied plant (8.22 g plant-1 and 2.07 t ha-1) due to increased number of pods plant-1, seeds pod-1 and pod size. In contrast, 6.0 mgL-1 Miyobi applications had the adverse effect on yield attributes and yield compared to 5 mgL-1 Miyobi application indicating inhibitory effect of Miyobi at high concentration of 6 mg L-1 on mungbean. Therefore, Miyobi with 5 mg L-1 may be applied for increased seed yield of mungbean.
