Effect of Sowing Methods and Some Weed Control Treatments on Yield and Yield Components of Wheat

Abstract

The aim of the study was to examine the response of wheat cultivar Sakha-93 to 3 weed control treatments and two sowing methods.The experiment included 6 treatments which were the combinations of two sowing methods 1-in ridges 2-rows and response of wheat cultivar Sakha-93 to 3 weed control treatments 1-Unweeded (control) ; 2-Hand weeding twice at 30 and 60 DAS 3-Chemical weed control by Panther 55% Sc at post emergence. The treatments were arranged in split plot design in four replicates, sowing methods in main plots and weed control treatments in subplots. Combined analysis used for the two seasons. Data indicated that sowing wheat c.v Sakha-93 in ridges surpassed in rows for no. of tillers ; spikes/m 2 ; spike length ; spike weight ; grains weight/spike ; grain; straw; biological yields as kg/fed.; harvest index % ; protein ; phosphorus and K yields as kg/fed. On the other hand, sowing in rows produced taller plants, heavier 1000 grains weight. . Results showed that chemical weeded had superiority in total, broad leaved ,grassy weeds either fresh or dry/m 2 at both samples 75 and 105 DAS ,also, in no. of tillers/m 2 ; no. of spikes/m 2 ; spike length ; spike weight ; grains weight/spike ; 1000-grains weight ; grain yield/fed. ; harvest index% ; protein ,P,K yields (kg/fed.) whereas hand weeding produced tallest plants , highest protein ,P,K% in grains. Interaction of sowing method in ridges and chemical weeded significantly surpassed other treatments in no. of tillers/m 2 ; no. of spikes/m 2 ; spike weight ; straw and biological yield as kg/fed. Interaction of sowing method in ridges and hand weeding gave the highest content of protein ; phosphorus and potassium in wheat grains as kg/fed.

Sustainability of Wheat (Triticum Aestivum L.) Yield and Improvement of Seed Quality Through Probiotic and Organic Soil Amendment

“…The boosting harvest index might be the continued supply of nutrients and higher dry matter distribution towards grain formation provided by the poultry manure treatment combination. This result was in agreement with the investigation of Kabesh et al (2009) and Khan et al (2018).…”

Impact of Integrated Weed Management on Productivity of Bread Wheat and Associated Weeds

“…This method seems to be creating favorable conditions around wheat plants such as sufficient water and nutrients supplies, light penetration, CO 2 concentration and other factors affecting wheat growth and development. These results are in agreement with those obtained by Kabesh et al (2009). Increasing seeding rate from 45 to 60 to 75 kg/fed.…”

“…However, the difference between ridges and rows was not significant in the 2 nd season (Table 4). Kabesh et al (2009) and Rahman et al (2010) found similar results. Inversely, the wet method produced the least number of spikes in both seasons.…”

SOME BIO-CHEMICAL NITROGEN AND PHOSPHORUS FERTILIZATION REGIMES IMPACTS ON WHEAT (Triticum aestivum L.) PRODUCTIVITY

“…Sawires (2000) mentioned that application of 100 kg N/fad., gave the highest weight of wheat grains /spike, also Sohail et al (2002), Nassar et al (2004), Abdul Galil et al (2008 Kandil et al (2011) reported that inoculated wheat plants produced higher grain weight compared to non-inoculated plants. The effective role of the dual application of NR 2 Rfixer biofertilizer and chemical N fertilizers was observed on increasing grain weight /spike as recorded by Hassanein and Gomaa (2001), Zaki et al (2007) and Kabesh et al (2009). Phosphorus fertilization regimes influenced significantly wheat grain weight /spike in both seasons and their combined (Table 2).…”

“…,Abbasdokht (2008),Badr et al (2009),Kabesh et al (2009),Metin et al (2010),Radwan et al (2013) as well asYousefi and Barzegar (2014), confirmed the meliorating role of biofertilization on 1000-grain weight.…”
