Abstract

A field experiment was implemented in Al–Garma, Al–Anbar province during fall season, 2004 to assess the effect of planting methods (redges and rows) and distances between hills (5, 10, 15, 20, 25 cm) on some growth, seed yield and yield quality of Mung bean (Vigna radiata L.) local cultivar. Split-plot arrangement was used according to randomized complete block design with four replicates. The results obtained were as follows.
Redge method was the superior in growth traits, number of pods/plant (59.37 pods), 100 seed weight (3.49 g), seed yield (1479.89kg/ ha), protein yield per area unit (462.83 kg/ ha) compared with rows method (50.09 pods/ plant, 3.37 g/ 100 seed, 1193.06 kg seed/ ha, 370.56 kg protein/ ha). While rows method was superior in number of seed per pod. The two methods were not significantly differed from each other in harvest index and protein ratio of seed.
Increasing the distance between hills led to significant increase in all studied traits except harvest index, which significantly increased in narrow distance (5 Cm). Planting distance of 25 cm had the highest averages of growth traits, number of pods/ plant and protein ratio in seed, While the distance of 20 cm had the highest averages of number of seed/pod, 100 seed weight, seed and protein yields per area unit.
Interaction between planting method and distance between hills significantly effected in most growth traits, yield and yield quality. Plants in redges under effect of 20 cm distance gave the highest dry matter yield, seed yield and protein per area unit, whereas the lowest averages of these variables was obtained from plants sowing in rows under the effect of narrow distance (5 cm).
From this study, it can be concluded that the highest seed and protein yield were achieved using redge method with 20 cm distance between hills.
