Effect of sowing methods and distances between hills in characteristics of vegetative and root growth and seed yild of mung bean plant Vigna radiata L.


Field experiment was conducted in Al-Thabitia village, Garma, Al-Anbar province during autumin season of 2004. The objective of this experiment to know the effect of planting methods (Rows & Lines) and distance between hills (5 , 10 , 15 , 20 , 25) cm in characteristics of vegetative and root growth and seed yield of mung bean plant/Local variety.In this experimental using split-plot system according to random complete block design (R.C.B.D.)with four replicates. The results were:Rows planting method gave ahighest mean of dry plant weight (27.30 g), number of root branches for main root (19.04 branch/root) and dry weight of root (2.10 g/root) as compared with lines planting method (22.27 g/plant, 14.01 branch/root, 1.87 g/root) respectively.Increasing the space between hill caused to increasing in all mean of characters study (plant height, stem diameter, branchs No./plant, plant dry weight, root length, No. of secondary root/main root, dry root weight, seed yield/plant) until reached a maximum mean in the wide space (25 cm).The interaction between planting methods and hills spaces effect significantly in No. of branches, plant dry weight and root dry weight, in general the plants sowing in two methods of planting under the effect of wider space (25 cm) gave a highest mean for above characters while the plants sowing in lines method under the effect of narrow space (5 cm ) gave alowest value of this characters.
