Abstract/ Executive Summary:

An experiment was carried out to study the effect of planting date and plant density on the yield and yield attributes of five varieties of mungbean. The experiment comprised of four planting dates viz. 03 February,18 February, 05 March and 20 March, five varieties viz. BARIMung-2, BARIMung-3, BARIMung-4, BARIMung-5 and BINA Mung-2 and three planting densities viz., 20x20 cm, 30x10 cm and 40x30 cm. The experiment was laid out in a split-split plot design with three replications. It was observed that early planted (03 and 18 February) crops produced higher yield as compared to late planted (05 and 20 March) crops. Variety BARIMung-2, BARIMung-3 and BARIMung-4 produced higher seed yield as compared to variety BARIMung-5 and BINAMung-2.The 30x10 cm plant density always showed the highest yield performance. Variety BINAMung-2 produced the highest branches plant^-1 when planted on 03 February at a spacing of 40x30 cm. The highest pods plant^-1 was found in the variety BARIMung-3 when planted at a density of 30x10 cm and planted on 18 February. Pod length was the highest in variety BARIMung-5 planted on 05 March with a plant density of 20x20 cm. The highest 1000- seed weight was obtained in case of variety BARIMung-5 planted on 03 February at densities of 20x20 cm and 30x10 cm. Variety BARIMung-2 planted on 3 February at plant density of 30x10 cm significantly produced the highest seed yield and harvest index and the lowest seed yield and harvest index were found in the variety BARIMung-3 planted on 20 March at a plant density of 40x30 cm.

Program Area: Knowledge Management

Commodity: Mungbean

Objectives:

The present study was therefore undertaken to find out (I) the suitable planting date of mungbean specially in kharif-I season, (ii) the relative yielding ability of five varieties of mungbean, (iii) optimum planting density of mungbean and (iv) yield performance of mungbean varieties with combined effect of planting date and plant density.

Methodology:

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh during the period from February to June, 2002. The soils of experimental plot was silty loam with pH 6.7, organic matter 1.25%, total nitrogen (N) 0.05%, available phosphorus (P) 12 ppm, available sulphur (S) 16 ppm and exchangeable potassium (K) 0.38 me 100 g ^-1 soil. The experiment comprised of five varieties of mungbean viz., (I) BARIMung-2, (ii) BARIMung-3, (iii) BARIMung-4, (iv) BARIMung-5 and (v) BINAMung-2; four planting dates viz., (I) 03 February, (ii)18 February, (iii) 05 March and (iv) 20 March, 2002 and three planting densities represented by three plant spacings viz., (I) 20x20 cm, (ii) 30x10 cm and (iv) 40x30 cm. The experiment was laid out in a split-split plot design with three replications assigning planting dates in the main plots, varieties in the sub-plots and planting densities in the sub-sub-plots. Size of each unit plot was 6 m² (3x2 m). Experimental land was uniformly fertilized with 20 kg N,40 kg P₂O₅ and 20 kg K₂O ha^-1 in the form of urea, triple super phosphate (TSP) and muriate of potash (MP), respectively, at final land preparation. Crop management practices such as gap filling, weeding, thining and plant protection measures were done as per requirement. Data on yield attributes were taken from 5 randomly selected plants per plot. The crops of 33 m² (3x1 m) in each plot were harvested by picking of pods at different dates as per maturity of different varieties. Yield was recorded at 16% moisture content of mungbean seed which was the safe level without reducing germination. The collected data were compiled and tabulated properly for statistical analysis. Analysis of variance was done with the help of computer package M-stat program. Differences among treatment means were tested with Duncan^,s multiple range test (DMRT) and Least significant difference (LSD) test where necessary.

Achievement/Findings:

From the present study it may be concluded that 3 and 18 February planting dates were more suitable for the cultivation of varieties BARIMung-2 and BARIMung-3 at a planting density of 30x10 cm. The variety BARIMung-5 was found to produce the highest 1000 seed weight, the longest pod and the shortest growth duration.
