Effect of planting techniques and weed control treatments on growth and yield of wheat

Abstract

A field experiment was conducted to study the effect of different planting techniques (conventional drill sowing at 16, 18 and 20 cm row spacing and bed planting with two and three rows in main plots) and weed control treatments (pinoxaden 50 g/ha, ready-mix (RM) of carfentrazone and metsulfuron 25 g/ha and pinoxaden 50 g/ha + RM of carfentrazone and metsulfuron 25 g/ha in subplots) on growth and productivity of wheat. The grain yield under row spacing 18 cm (53.30 q/ha), and 20 cm (52.02 q/ha), and three rows bed planting (51.96 q/ha) were recorded statistically at par with each other and significantly higher than 16 cm (49.37 q/ha) row spacing and two row bed planting (48.53 q/ha). Gross returns (Rs. 95637/ha) and net returns (Rs. 43929/ha) and B:C ratio (1.85) were record-ed higher under 18 cm row spacing compared to other planting techniques. Tank mixed application of pinoxaden 50 g/ha + RM of carfentrazone and metsulfuron 25 g/ha applied at 35 days after sowing (DAS) controlled both grassy and broad leaved weeds effectively with lower values of weed dry matter accumulation (7.67 g/ha) and produced growth parameters, yield attributes and yield (53.16 q/ha) at par with weed free treatment. In light of the results to maximise productivity, 18 cm row spacing may be practiced and tank mix application of pinoxaden (50 g/ha) + RM of carfentrazone and metsulfuron (25 g/ha) is recommended to reduce losses due to complex weed flora in wheat.

Effect of Planting Patterns and Weed Competition on Growth, Yield and Quality of Wheat (Triticum aestivum L.)

“…The biological (grain+straw) yield, straw yield and harvest index was significantly better in cross sowing and three rows/bed than two rows/bed and flat sowing techniques. These results also same with Sudesh et al (2017). Among weed competition treatments, the all yield parameters were significantly higher in no competition treatment than all other weed competition treatments.…”

Phenological Behaviour, Weed Dynamics and Productivity of Green Gram Influenced by Weed Control Treatments

“…The number of market entry of herbicides with new mode of action has reduced. For effective management of complex weed flora, there is need to use mixture of existing herbicides (Devi et al, 2017a), which should have a wide spectrum of weed control without crop injury and residual effect on succeeding sensitive crops and can enhance the productivity of crop (Devi et al, 2017b). Every (crop) plant has a definite temperature requirement for attaining certain phonological stages.…”

Enhancing Profitability and Yield Potential of Weed Controlling in Green Gram (Vigna radiata L.) under Central Plains of Punjab

“…For active managing of difficult weed flora, there is necessity to usage combination of different new weedicides Devi et al, (2017b). It would have broad range of weed controllers causing no harm to plant, have little lasting effect on the crop and boost agricultural yield and profitability in green gram crop Devi et al, (2017a). The research work was carried out with following objectives: i) To study the effect of herbicides use on weed density in green gram field.…”
