“…Results also indicated that there was no significant effect between hand hoeing twice and nonweeded treatment on dry weight and number of nodules per plant -1 . Similar results were obtained by Attia (2002), Singh & Wright (2002) and El-Metwally & Shalby (2007).…”

o número, peso fresco e seco dos nódulos, raiz, caule e peso seco total da planta, enquanto duas capinas manuais aumentaram significativamente das características citadas. Duas capinas manuais e os herbicidas de pré-emergência aplicados nas doses recomendadas aumentaram o rendimento da soja e seus atributos. Duas capinas manuais produziram maiores números de vagens por planta, peso de vagem por planta e número de sementes por planta em 140,7; 150,0 e 59,8%, respectivamente, comparado ao tratamento capinado. Por outro lado, oxadiargyl aplicado na dose recomendada (480 g ha -1 ) apresentou maior rendimento de semente (g planta -1 ), rendimento de semente (kg ha -1 ) e rendimento biológico (g planta -1 ) que o tratamento sem capina em 87,3; 85,0 e 88,2%, respectivamente. Prometryn na dose de 1,50 kg ha -1 , seguido de duas capinas manuais produziu a maior percentagem de proteína na parte aérea e sementes como também de óleo na semente, comparado a outros tratamentos de controle de plantas daninhas.Palavras-chave: Glycine max; herbicidas, manejo de plantas daninhas.ABSTRACT -Two field experiments were conducted at the experimental farm of the National Research Centre at Shalakan, Kalubia Governorate, Egypt, during 2006 and 2007 seasons, to study the effect of three pre-emergence herbicides, prometryn [at the rate of 0.75, 1.5 and 2.25 kg ha -1 ], oxadiargyl [at the rate of 240, 480 and 720 g ha -1 ] and butralin [at the rate of 1.20, 2.40 and 3.36 kg ha -1 ], two hand hoeing treatments and a nonweeded check, on weed infestation, nodulation, growth, yield and yield attributes of soybean plants. Two hand hoeing treatments resulted in the highest weed depression expressed as the lowest fresh and dry weights of broadleaved, grassy and total weeds. The reduction percentage in weed dry matter compared to the nonweeded treatment was 98.3, 92.64 and 96.9% in broadleaved, grassy and total weeds, 856 respectively. Application of the three herbicides at higher or recommended doses significantly reduced fresh and dry weight of the weeds compared to the nonweeded treatment. The results indicated that all the three herbicides at rates higher than the recommended markedly decreased the number, fresh and dry weight of nodules as well as root, shoot and total dry weight plant -1 , while application of two hand hoeing treatments significantly increased these traits. Two hand hoeing treatments and pre-emergence herbicides at the recommended rates markedly increased soybean yield and its attributes. Two hand hoeing treatments gave the highest values of number of pods per plant -1 , weight of pods per plant -1 and number of seeds per plant -1 by 140.7, 150.0 and 59.8%, respectively, compared to the nonweeded treatment. On the other hand, oxadiargyl at the recommended rate (480 g ha -1 ) was the best treatment for promoting seed yield (g plant -1 ), seed yield (kg ha -1 ) and biological yield (g plant -1 ) compared to the nonweeded treatment by 87.3, 85.0 and 88.2%, respectively. Prometryn at the rate of 1.50 kg ha -1 , followed by two...

“…Among those used for controlling weeds in faba bean, Igran (terbutryn), Fusilade (fluazifopbutyl), Basagran (bentazon), Gezagard (prometryn), Amex (butralin) and Topstar (oxadiargyl) are the most prominent. Gezagard (prometryn) was used as pre-emergence herbicide in the control of a wide range of weeds in legumes (Singh & Wright, 2002). Some researchers have reported increased growth characters, yield and yield attributes of faba bean plants when prometryne was applied (Singh & Jolly, 2004).…”

“…The excessive nitrogen and biomass accumulation in the shoots of the 400 kg N treatment caused crop lodging and slightly depressed the seed yield and seed nitrogen content. Singh and Wright (2002) studied the effects of three herbicides on the node number, growing patterns and yield of two pea cultivars under greenhouse conditions. Double doses of Basagran (active ingredient: bentazone) caused chlorosis of the plants.…”

Based on the results of earlier greenhouse tests, a field experiment was conducted to evaluate the effects of three different herbicide combinations (clomazone, flumioxazine and pendimethaline combined with bentazone) at increasing nitrogen levels on the nitrogen uptake of green pea and common lambsquarters ( Chenopodium album L.). Nitrogen was administered to the pea plants in the form of ammonium nitrate at increasing levels: 0, 100, 200 and 300 kg/ha. The experimental soil was loamy Ramann’s brown forest soil (Eutric Cambisol). Green peas were grown to green maturity and harvested according to standard agricultural practices. Following harvest, the fresh and dry weight of the pea and weed shoots were recorded. The nitrogen, phosphorus and potassium contents were determined from dried plant samples after digestion with concentrated sulphuric acid.The main results can be summarized as followsThe addition of nitrogen to the treatments considerably altered the growing potential of pea plants, especially at the early growth stage, where an increase in dry biomass of nearly 30% was observed. Yield biomass decreased in the nitrogen treatments. The nitrogen concentration, which increased in every treatment, was directly correlated to the addition of nitrogen fertilizer. Herbicides mainly influenced the vegetative growth of the plants. Pendimethalin and flumioxazin indirectly caused an increase in the dry biomass of the shoots by killing the surrounding weeds.
