A COMPERATIVE STUDY ON NITROEENOUS AND BIOFERTILIZER ON GROWTH AND YIElD OF MUNGBEAN

Abstract

The experiment was conducted at the Research Farm of Sher-e-Bangla Agricultural University (SAU). Dhaka during the period from April 2011 to July 2011 to study the performance of two mungbean varieties without Bradyrhizobiuzn and with nitrogen/Bradyrhizobiurn. There were six treatment combinations and four replications were laid out in Randomized Complete Block Design (RCBD) technique. The Bradyrhizobiurn strain BARI RVr-403 was used for the above experiment. The selected varieties were BARI Mung-5 and BARI Mung-6. The above varieties were tested with or without nitrogenlBradvrhizohiwn inoculation. BARI Mung-5 performed better than BARI Mung-6 variety in respect of different parameters like nodule number and weight, root weight and shoot weight, root length and shoot length, pod length and pods plant'. But BARI Mung-6 produced higher 1000-seed weight, stover yield, seed yield, plant height and seeds pod' than BARI Mung-5. Bradyrhizohiurn inoculation significantly increased nodule number and weight. seed yield, stover yield, plant height. 1000-seed weight, pods plant* seeds pod'. N content in seed and stover, N uptake by stover and seed. Interaction ellects revealed that BARI Mung-5 with Bracs5.'rhizohium inoculation recorded the highest nodulation but inoculated BARI Mung-6 recorded the highest seed yield compared to other treatment combinations. Non-inoculated BARI Mung-5 gave the lowest yield. The highest N uptake by seed and stover was found in BARI Mung-6 x Inoculum treated plot. Economic analysis revealed that the highest BCR (1.31) was noted in inoculated BARI Mung-5.
