| Abstract | ||||
| Two field experiments were carried out in the Experimental Farm of the National Research Centre at Shalakan, Kalubia Govemorate, Egypt in the winter seasons of 200012001 and 2001/2002. The objective of the experiments was to investigate the effect of some weed control treatments (i.e. A. Early pre-planting : Paraquat and hand hoeing, B. After planting: Butralin, Bentazon, Fluazifop-butyl, SWalln + Bentazon, Butralin + Fluazifop-bl.1y1. 8entazon + fluazifop-butyl and one hand hoeing) on growth, yield and yield components as well as chemical composition and associated weeds of pea plants c:.J. Master 8. The most important results obtaine.d from this study could be summarized as follows: All weed control treatments significantly decreased fresh and dry weight of broad-leaved, grasses and total weeds after 50 and 70 days from sowing. Hand hoeing as early pre-planting weed control treatment gave the best control of broad- leaved, grasses and total weeds of both seasons. Also, hand hoeing as after planting weed control treatment recorded the highest decrease in fresh and dry weight of broad-leaved and total weeds of both seasons. While, Fluazifop-butyl as after planting weed control treatment recorded the lowest fresh and dry weight of grass weeds of both seasons. Hand hoeing as early pre-planting caused a signifICant increase in plant height after 50 and 70 days from sowing, pod length, fresh weight of pod, number of green pods/plant. weight of 100 green seeds, yield of green pods/plant, pod yield (tonlfed) and chemical composition of pea seed in both seasons as compared with both treatments. Whereas, Paraquat as early pre-planting treatment gave the highest values of number of leaves/plant, fresh and dry weight of plant after 50 and 70 days from sowing' and number of green seeds/pod when compared with hand hoeing and unweeded treatments. After planting treatments had significant effect on growth, yield and yield components as well as chemical composition of pea seeds in both seasons. Hand hoeing followed by that of Bentazon + Fluazifop-butyl as after planting exceeded other treatments. The interaction between early pre-p/anling and after planting weed control treatments had significant effect on some studied traits. Using hand hoeing as early pre-planting and hand hoeing as after planting Ireatments produced the lowest fresh and dry w.eight of total weeds after 50 and 70 days from sowing in both seasons as well as produced the highest plant height and pod yield (ton/fed) of pea in both seasons followed by that of using Paraquat as earty pre-planting and Bentazon + Fluazifop-butyl as after planting weed control trealments as compared with other treatments. While. application of Paraquat as early pre-planting and hand hoeing as after planting treatment produced the highest number of green pods/plant in both seasons. | ||||
