The evaluation of physiological characters of mungbean (Vigna radiata L. Wilczek) under planting pattern and starter N fertilizer

A field study was carried out to evaluate the changes of protein content, yield and yield components and physiological characters of mungbean (Vigna radiata L. Wilczek) under planting pattern; 1- Broadcasting (random pattern), 2- Strip pattern (50 cm inter row spacing and 10 cm intra row spacing), 3- Square pattern (hill pattern, 50 cm inter row spacing and 50 cm intra row spacing) as main plots and starter N fertilizer at rate of 0, 25 and 50 kg/ha as sub plots. The results indicated that maximum grain protein yield (348.48 kg/ha) associated to square pattern and application of 50 kg/ha starter N fertilizer significantly had greater grain protein percentage (24.86%) as compared to the control (application of 0 kg/ha starter N fertilizer) (23.7%). Data showed that application of 25 and 50 kg/ha starter N fertilizer had better effect on grain protein yield of 273 and 274 kg/ha, respectively compared to the control (223.7 kg/ha). Maximum and better rate of LAI, CGR, NAR and RGR were related to the treatment of application of 50 kg/ha starter N fertilizer and treatment of square pattern. These treatments also had moderate reduction in these physiological characters. Strong positively correlations were observed between grain protein yield and grain yield, TDM (Biological yield), number of pod per plant and 1000- grain weight.
