“…Hence, there is need to remove weeds in the early stage of crop growth to avoid competition. The most common weeds that grow in rapeseed mustard are Avena ludoviciana, Phalaris minor, Chenopodium album, Rumex dentatus, Anagallis arvensis, Convolvulus arvensis, Melilotus indica and Cirsium arvensis" [3]. The critical period of crop weed competition in mustard is 15-40 DAS and weeds cause about 25-50 % of yield loss [4] depending on weed flora, intensity and stage of the crop.…”

Mustard (Brassica juncea L.), a species of the cruciferous family, is the world's third most significant oilseed crop, following soybean and palm. Mustard seeds range in oil content from 37 to 49%. India is the fourth-largest producer of mustard and rapeseed in the world. The most significant issue causing mustard's low yield is weed control. Crop yields are significantly reduced by weeds; in the case of mustard, this can mean a complete failure rate of 15–30%. Crop plants compete with weeds for nutrients, sunlight, space, and water. In addition to lowering crop quality, weeds pose a number of nutritional and environmental hazards. In mustard crops, weed competition is particularly important in the early stages since the crop grows slowly in the first 4–8 weeks after sowing. On the other hand, 15–40 days are the critical window for crop–weed competition. Weed control must be carried out appropriately and on time in order to maximize mustard growth and production. During the early stages of crop growth, 25–30 days after sowing, the traditional practice of hand weeding once is insufficient because weeds always reappear after manual weeding, irrigation, or winter rainfall. More importantly, though, is that these weeds drain a large amount of the soil's moisture and nutrients. Though hand weeding mustard is simple, the expense of doing so is significant due to the scarcity of labor at the appropriate time and the uncontrolled growth of various intra row weeds. Weeds may become tolerant of herbicides despite their regular and high dosage application. Therefore, combined approaches could be the best option to control the complex weed flora in mustard.

A field experiment was conducted during rabi season (November to February, 2020–21) at College Farm, College of Agriculture, Rajendranagar, Hyderabad. The farm is geographically positioned at 17°19’16.4” North latitude and 78°24’43” East longitude and at an altitude of 542.3 m above the mean sea level. According to troll’s climatic classification, it is categorized under semi-arid tropics (SAT). The experimental field was sandy loam texture with available nitrogen (223 kg ha-1), available phosphorus (30.87 kg ha-1) and potassium (375.72 kg ha-1). Mustard variety NRCHB-101 was sown with seed rate of 4 kg ha-1. The seeds were sown in solid rows 40 cm apart between rows and at a depth of 3‒4 cm and covered with loose soil immediately after seeding. The experiment was laid out in randomized block design with twelve treatments and replicated thrice. The data was analyzed using standard statistical techniques. Among different weed management practices, higher nutrient uptake (59.57, 24.51, 52.46 kg ha-1 ) by crop were observed under intercultivation and hand weeding at 15 and 30 DAS and it was on par with Oxadiargyl 6% EC 0.09 kg ha-1 PE fb intercultivation at 30 DAS. Similarly higher gross and net returns (68933/- and 42952/-) were noticed with intercultivation and hand weeding at 15 and 30 DAS and it was on par with Oxadiargyl 6% EC 0.09 kg ha- 1PE fb intercultivation at 30 DAS. Higher B:C ratio was noticed under Oxadiargyl 6% EC 0.09 kg ha-1 PE fb intercultivation at 30 DAS (2.96).
