GROWTH AND YIELD OF MUNGBEAN (BARI Mung-6) AS INFLUENCED BY DIFFERENT LEVELS OF NITROGEN

Abstract

A research work was conducted at Sher-e-Bangla Agricultural University Farm, Dhaka during the period from March, 20014 to July, 2014 to study growth and yield of mungbean (BARI Mung-6) as influenced by different levels of nitrogen and phosphorus. The experiment included four levels of nitrogen viz., 0, 20, 40 and 60 kg N ha -1 and three levels of phosphorus viz., 0, 20 and 40 kg P ha -1 . The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Nitrogen fertilizer had significant effect on growth and yield of mungbean. Application of nitrogen @ 60 kg ha -1 gave the highest plant height, number of leaves plant , number of branches plant -1 , number of pods plant -1 -1 , pod length, number of seeds pod , 1000-seed weight, seed yield and stover yield. In all cases the lower values were found with the untreated control treatment. Phosphorus fertilizers also had significant effect on growth and yield of mungbean. Application of phosphorus @ 40 kg ha -1 produced the highest plant height, number of leaves plant , number of branches plant -1 , number of pods plant -1 , pod length, number of seeds pod -1 , 1000-seed weight, seed yield and stover yield. In all the cases lower values were found with the control treatment. Nitrogen @ 60 kg ha was found statistically superior to all other treatments. Nitrogen in combination with phosphorus showed significant effect on yield and yield attributes of mungbean. Combined application of nitrogen @ 60 kg ha -1 and phosphorus @ 40 kg ha -1 resulted the highest plant height, number of leaves plant , number of branches plant -1 , number of pods plant -1 -1 , pod length, number of seeds pod , 1000-seed weight, seed yield and stover yield. On the other hand, in all the cases lower values were found in the untreated control treatment.
