“…Weed density was higher in weed containing plots because weeds are growing according to the treatments for whole season. Similar findings are revealed by (Chinnusamy and Chinnagounder, 2013;Hargilas et al, 2015). Total weed dry weight of weed increase as the weed age increases.…”

A field study was conducted to evaluate the effect of horse purslane on mungbean productivity at the research farm of MNS-University of Agriculture Multan during Kharif season of 2018. For this purpose, 10 experimental treatments including T1 (weed free for the whole season), T2 (horse purslane free for 20 days after emergence, DAE), T3 (horse purslane free for 40 DAE), T4 (horse purslane free for 60 DAE), T5 (all weeds free for 20 DAE), T6 (all weeds free for 40 DAE), T7 (all weeds free for 60 DAE), T8 (weedy check with all weeds), T9 (weedy check except horse purslane) and T10 (weedy check containing only horse purslane) were used. The experiment was carried out under RCBD (Randomized complete block design) and replicated thrice. Data was recorded for different growth and yield related traits of mungbean by using standard procedures. Data recorded were statistically analyzed and treatment means were compared by using Tuckey’s test @ 5% probability level. Results showed that maximum number of grains per pod (10.66), number of pods plant-1 (28.00), 1000 grain weight (68.40 g), grain yield (1.9 t ha-1) were noticed in the plots which were kept weed free. Hence it may be concluded that for maximum yield, farmers should control horse purslane at early stage of the crop.

“…The reduction in weed dry weight under said treatments might be due to pendimethalin, which inhibits the cell division and root and shoot growth of the weeds preventing them from emerging, particularly during the crucial development phase of the crop. The results were in accordance with the finding of Gnanavel and Babu (2008) and Chinnusamy and Chinnagounder (2013). The highest weed dry biomass of monocot (18.1g/m 2 ), dicot (16.3 g/m 2 ) and total weed (25.6g/m 2 ) were recorded under weedy check treatment (Table 1).…”

A field experiment was conducted for two consecutive Kharif seasons of 2014 and 2015 at research farm of AICRP-Weed Management, AAU, Anand to study the integrated weed management in cotton under irrigated condition. Pre-emergence application of pendimethalin 1000 g/ha fb hand weeding twice at 20 and 50 DAS, and pyrithiobac-sodium + quizalofop-p-ethyl (62.5 + 50 g/ha) as PoE fb directed spray of glyphosate 2000 g/ha at 60 DAS recorded significantly lower weed dry biomass as well as higher seed cotton yield and benefit cost ratio as compared to rest of the treatments. The weed control efficiency of these treatments proved to be 90 and 86% during 2014 and 2015, respectively.

“…ha -1 at 35 DAS + intercultivation and hand weeding at 60 DAS drastically reduced the dry weight of weeds and increased the WCE, CGR, total number of bolls harvested, boll weight, seed cotton yield and uptake of nutrients (Prabhu et al, 2012). Higher WCE was recorded under pre-emergence application of pendimethalin at 1.0 kg ha -1 on 3 DAS + hand weeding on 45 DAS (Nithya and Chinnusamy, 2013). PE application of pendimethalin at 1.0 kg a.i.…”

“…According to Prabhu (2010), weed infestation had no effect on quality characters of cotton but affected the yield of cotton. Muhammad et al (2013) revealed that weedy check decreased the seed cotton weight boll -1 , seed index, seed cotton yield and ginning out turn of cotton compared to other treatments.Nithya and Chinnusamy (2013) concluded that, if the field left uncontrolled with weeds not only reduced crop yield but also increased the weed seed bank in soil which created problems for succeeding crop. Hence, weeds play a significant role in reducing the seed cotton yield.…”

Cotton is one of the most important commercial crops in India. Cotton growth is very slow in the initial stages of its life cycle and row spacing is wider which provides ample space for the growth of different categories of weeds and thus become a source of competition for water as well as nutrients, thereby impeding its growth. Weeds are major constraints that reduce the crop yields since they compete with crop for the nutrients, moisture, light and space. The integration of different weed management practices would be a viable option for broad spectrum weed control and enhancement of cotton productivity. Thus, weed management has several aspects such as physical, mechanical, cultural, chemical and integrated weed management methods. A brief review of research accomplishment made at various places on different fields related to this investigation is reviewed in this paper.
