Abstract/ Executive Summary:

An experiment was carried out at the Agronomy Field of Sher-e-Bangla Agricultural University, Dhaka during the period from March to June 2015 (Kharif-I season) to find out the growth performance and development attributes of mungbean (Vigna radiate L.) as influenced by organic manure and inorganic fertilizer. The experiment consisted of two factors: factor A: five levels of manures and inorganic fertilizers [T0 = Control (no fertilizer or manure), T1 = Recommended dose of fertilizer (R) (45 kg urea ha-1 + 100 kg TSP ha-1 + 58 kg MoP ha-1 ), T2 = R + cow dung (3 t ha-1 ), T3 = R + poultry manure (2 t ha-1 ), T4 = R + vermicompost (2.5 t ha-1 )] and factor B: two mungbean varieties; (V1 = BARI Mung 5 and V2 = BARI Mung 6). The experiment was laid out in split- plot design with three replications. The growth performance and development attributes of Mungbean varieties were found significant with the combined effect of different organic manures and recommended doses of inorganic fertilizers. The largest plant height, number of leaves plant-1 , number of branches plant-1 , dry weight of plant, minimum days to first emergence, 80% emergence, 80% flowering and 80% pod maturity (46.05 cm at 55 DAS, 24.16 at 55 DAS, 7.92 at 55 DAS, 40.68 g at 55 DAS, 1.80 days, 3.16 days, 32.21 days and 46.56 days, respectively) were found from the combined effect of V2 varieties with T4 treatment. Among the different treatment combination T4 [(recommended doses of fertilizer + vermicompost (2.5 t ha-1 )] showed the best results. So, BARI Mung 6 performed the best performance with the application of vermicompost @ 2.5 t ha-1 with the recommended dose of fertilizer.

Objectives:

Present experiment conducted with an aim to test the performance of organic manures and inorganic fertilizers on the growth and development attributes of mungbean varieties.

Methodology:

2.1 Experimental Site The experiment was conducted at the Research Farm of Sher-e-Bangla Agricultural University (SAU), Dhaka and it was in 24.09° N latitude and 90.26° E longitudes. The area belongs to the Agro ecological Zone (no.28): (Madhupur Tract). 2.2 Climate and Soil The climate of the experimental site is subtropical, wet and humid. Heavy rainfall occurs in the monsoon (mid-April to mid-August) and scanty during rest of the year. The soil of the 2.3 Experimental Treatments Mungbean varieties were used in the experiment. The experiment consisted of two factors: factor A: five levels of manures and inorganic fertilizers [T0 = Control (no fertilizer or manure), T1 = Recommended dose of fertilizer (R) (45 kg urea ha-1 + 100 kg TSP ha-1 + 58 kg MoP ha-1 ), T2 = R + cow dung (3 t ha-1 ), T3 = R + poultry manure (2 t ha-1 ), T4 = R + vermicompost (2.5 t ha-1 )] and factor B: two mungbean varieties; (V1 = BARI Mung 5 and V2 = BARI Mung 6). The experiment was laid out in split plot design with three replication. Each block of 10 plots resulting 30 plots in total. The size of each unit plot was 6 m2 . The distance between plots 0.5 m and replication 1.0 m. 2.4 Crop Husbandry The experimental land was prepared and weeds, stubble and crop residues were removed. Except for urea, all manures (cow dung, poultry manure and vermicompost) were applied along with TSP and MoP as per treatments during the final land preparation. All manures (cow dung, poultry manure and vermicompost) were applied as treatments each different plot of last land preparation. The urea was applied for two intervals: First half was applied during last land preparation and rest was applied at 25 DAS followed by light irrigation. Healthy seeds of mungbean @ 35 kg ha-1 were sown by hand as uniformly as possible in furrows with 15 cm hills to hill distance and 30 row to row distance. Seeds were sown in the afternoon and immediately covered with soil to avoid sunlight. Gap filling, weeding, application of irrigation water and plant protection measures were taken properly when needed. 2.5 Data Collection Ten pre-selected plants per plot from which different data were collected. Data on the following parameters were recorded during the course of the experiment such as - plant height, number of leaves plant-1 , number of branches plant-1 , dry weight of plant (g plant-1 ), days to first emergence, days to 80% emergence, days to 80% flowering and days to 80% pod maturity. Total dry matter weight of stem plant−1 (g) was recorded at different DAS by uprooting three random plant samples and separating the stem carefully. The plant samples were then oven dried at 72 °C temperatures. 2.6 Statistical Analysis All the collected data were tabulated and analyzed statistically using analysis of variance technique and later Least Significance Difference (LSD at 5%) for comparing the treatment means, by MSTAT-C software.

Achievement/Findings:

Irrespective of varieties and doses, plant height, leaves plant-1 , branch plant-1 , dry weight of plant and least days to 80% emergence, 80% flowering and 80% pod maturity were increased (18.07%), (14.99%), (26.92%), (67.00%), (55%), (13%) and (16%), respectively with applying vermicompost (2.5 t ha-1 ) and inorganic fertilizers (45 kg urea ha-1 + 100 kg TSP ha-1 + 58 kg MoP ha-1 ) than that of control. Both BARI Mung 5 and BARI Mung 6 performed the best two on most of the growth and developmental attributes. Finally, vermicompost (2.5 t ha-1 ) and best dose of inorganic fertilizers (45 kg urea ha-1 + 100 kg TSP ha-1 + 58 kg MoP ha-1 ) with BARI Mung 6 exhibited the superior combinations than that of control on most the limits studied.
