Abstract/ Executive Summary:

The experiment was conducted at Regional Agricultural Research Station, Jessore during Kharif-I, 2014 to find out the Zn efficient mungbean variety. Two levels of zinc viz. T_{1 =}control, T_{2 =}application of Zn @ 2 kg/ha were used in mungbean varietal plot. Six mungbean varieties viz. BARI Mung-2, BARI Mung-5, BARI Mung-6, BU Mung-4, BINA Mung-5 and BINA Mung-8 were included in the experiment. In case of mungbean application of zinc showed remarkable variation among all the parameters except days to flowering and days to maturity. BARIMung 6 gave the highest yiled (1854 kg/ha) followed by BARI Mung-5 (1728 kg/ha) and BINA Mung-8 (1715 kg/ha) respectively in zinc applied plot. On the other hand, BARI Mung- 2 gave the lowest yiled (1222 kg/ha) in control plot. but it was significantly similar with that of zinc treated plot (1277 kg/ha). So, application of Zn @ 2 kg/ha was more effective for BARI Mung-6 cultivation.

Commodity: Fertilizer, Mungbean

Objectives:

The present investigation was undertaken to find out the effect of Zn on mungbean variety.

Methodology:

The experiment was conducted at Regional Agricultural Research Station, Jessore during Kharif 1, 2014 to find out the Zn efficient mungbean variety as well as suitable rate of Zn. Two levels of zinc viz. T_{1 =}control, T_{2 =}application of Zn @ 2 kg/ha were used in mungbean varietal plot. BARI Mung-2, BARI Mung-5, BARI Mung-6, BU Mung-4, BINA Mung-5 and BINA Mung-8 were included in the experiment. The experiment was laid out in a RCB design with 3 replications. The unit plot size was 4m x 3m. Zinc was applied to mungbean. Zinc was applied as ZnSO₄ (36% Zn). A blanket dose of fertilizer @ 20-20-20-5-1 kg/ha of N, P, K, S and B were as applied as basal. The sources of nutrients were urea, TSP, MoP, gypsum and boric acid. The initial soil samples at the depth of 0-15 cm from the experimental fields were collected and analyzed following standard methods in the laboratory. Seed of mungbean were sown 24 March, 2014. Mungbean seeds were sown with a spacing of 40 cm line. Weeding and other intercultural operations were down as and when necessary. Data on yield contributing character were recorded 10 randomly selected plants in each plot. Seed yield was calculated from the whole plot. Collected data were analyzed statistically.

Achievement/Findings:

In case of mungbean, application of Zinc showed remarkable variation among all the parameters. Control plot or zinc untreated plot flowered earlier (36 days) and matured (56 days), on the other hand, application of Zn @ 2 kg/ha treatment flowered later (37 days) and matured (57 days). The lowest number of pods per plant of mungbean (41) was produced in Zn control plot. Numerically the highest number of pods per plant (42), the heaviest seed (4.80g) , highest yield (1647 kg/ha) was produced by the application of 2 kg/ha of Zn applied plot. The lowest (1592 kg/ha) was recorded in the control plot. Different varieties of mungbean showed significant variation among all the parameters. BARI Mung-6 and BU Mung-4 flowered earlier (37 days). On the other hand, BINA Mung 8 flowered later (39 days). BARI Mung 6 and BU mung-4 showed earlier maturity (56 days) and rest of others showed late maturity(57 days). The highest number of pods per plant was produced by BARIMung 6 (46) followed by BINA Mung-8 ( 45). The lowest number of pods per plant was produced by BU Mung-4 (38) followed by BARI Mung 2(39), BINA Mung-5 (40) and BARI Mung-2 (41) respectively. The heaviest seed (5.16g) produced by BARI Mung-6. The highest seed yield was produced by BARI Mung-6 (1794 kg/ha) followed by BARI Mung-5 (1713 kg/ha) and BINA Mung-8 (1701 kg/ha). The lowest seed yield was produced by BARI Mung-2 (1250 kg/ha). All yield components under the study showed significantly variation except days to flowering and days to maturity by zinc level and variety interaction. The highest pods per plant produced BARI Mung-6 (46) followed by BINA Mung-8 (45) in zinc applied plot. On the other hand, the lowest pods per plant produced BU Mung-4 (37) followed by BARI Mung-2 (39) in control plot. The heaviest seed produced by BARI Mung-6 (5.16 g) followed by BINA Mung-8 (4.53 g) in zinc treated plot but it was significantly similar with that of control plot (4.49 g). BARI Mung-6 gave the highest yield (1854 kg/ha) followed by BARI Mung-5 (1728 kg/ha) and BINA Mung-8 (1715 kg/ha) respectively in zinc applied plot. On the other hand, BARI Mung-2 gave the lowest yield (1222 kg/ha) in control plot but it was significantly similar with that of zinc treated plot (1277 kg/ha).

Considering the above results, BARI Mung-6 produced the highest yield due to varietal performance as well as zinc interaction. So, zinc @ 2 kg/ha was more effective dose of BARI Mung-6 cultivation.
