in Rabi season to find out the effect of nutrient management and weed control practices on growth parameters of various treatments on wheat crop. The experiment was laid out in split plot design with three nutrient levels and six weed control practices and replicated thrice. Application of 75% RDF + 10 t ha -1 FYM + one spray of nano-urea @ 4 ml/lit noted greater effect on plant height, number of tiller, leaf area index and dry matter accumulation during both years of experimentation. In case of weed management, spray of Clodinofop + Metsulfuron (60 + 4 g a.i. ha -1 ) found more effective to increase the growth of wheat during both year of investigation. This treatment having better weed control and higher nutrient uptake resulted in higher growth. It can be concluded that application of 75% RDF +10 t ha -1 FYM + one spray of nano-urea @ 4 ml/lit with the spraying of Clodinofop + Metsulfuron (60 + 4 g a.i. ha -1 ) proved better to increase the growth of wheat crop.

“…Therefore, weed management practices raise the cost of cultivation and reduce the profit for farmers. The average cost of weed control is ₹4000 ha −1 for winter season crops, while it is ₹6000 ha −1 for crops that are grown during the rainy season [52].…”

Weeds are unwanted plants, which interfere with the crop production. Weeds compete with crops for resources, causing severe yield loss. Chemical weed control through herbicides is a quite effective and reliable strategy to manage weeds. Herbicides constitute a major share of the global pesticide market. However, the applied herbicides undergo losses in the agroecosystem in different ways (chemical degradation, microbial decomposition, photo-degradation, leaching, run-off, and volatilization), thus lowering the herbicidal action coupled with contaminating ecosystem and groundwater. Encapsulation of herbicides is an innovative approach that addresses issues associated with the application of herbicides for controlling weeds. Encapsulation represents the embedding of an active ingredient in shell of polymeric material to achieve the controlled release of the active ingredient at the desired rate. The encapsulation of herbicides enhances stability, solubility, and bioactivity and alters the release pattern of herbicide resulting in improved weed control efficiency. Further, encapsulation lowers the application rate of herbicides, which in turn reduces the residue carryover of herbicide in soil and minimizes the environmental hazards. Therefore, encapsulated herbicide formulation has greater significance in the future weed management and will become ground-breaking technology in the chemical era of weed control.

“…On the other hand, despite the technological level of basic crop cultivation, weeds remain a significant and complex problem that restrict the effective realization of the genetic potential of varieties and hybrids of agricultural crops (Yaduraju and Mishra, 2018). However, weeds are an integrated component of the overall functional life of any agrophytocoenosis, and they cannot be considered separately from the resulting total bioproductivity (Shaner and Beckie, 2014).…”

“…However, weeds are an integrated component of the overall functional life of any agrophytocoenosis, and they cannot be considered separately from the resulting total bioproductivity (Shaner and Beckie, 2014). Weeds at different densities and species composition can reduce crop yields between 5% and 80% (Singh et al, 2018;Yaduraju and Mishra, 2018). There is also a risk of weeds spreading and growing due to climate change and emergence of weed resistance to a number of herbicides (Jugulam et al, 2019).…”

There is limited information about the critical period for weed control (CPWC) in oilseed radish (Raphanus sativus L. var. oleiformis Pers.) This significantly limits the effectiveness of the applied technologies in its cultivation. The article focuses on the results of a long-term study (2013 to 2018) of the peculiarities of weed formation in oilseed radish agrophytocoenosis using different sowing technological models according to seeding rate and row spacing parameters. The study included the peculiarities of the species and generic composition of weeds and the basic attributes of the formation of species-specific amounts. The summed dominance ratio (SDR) was heterogeneous and co-oscillatory in the weed structure for both the formation of the number of individual species and their height dominance, which depended on the phenological stage of growth and crop development. In the general spectrum, the prevailing weed forms were identified with the highest potential for oilseed radish plants with an SDR greater than 1.0, which belong to groups I and VI according to environmental plasticity and stability, given the different conditions of the study period for both hydrothermal conditions and year index. In conclusion, a critical period for weed control (CPWC) in oilseed radish agrocoenosis was defined as a 5% reduction in crops ranging from 5 to 45 d after sprouting (DAS) for row sowing and a seeding rate of 4.0 million similar seeds ha-1 and 6 to 60 DAS for a variant of wide row sowing at a seeding rate of 0.5 million similar seeds ha-1 .
