“…Enhanced nitrogen application treatments recorded highest stover yield due to cumulative effect of greater value of growth attributes of higher plant height, leaf area, crop growth rate, absolute growth rate, dry matter production which to higher stover yield. These findings are in line with Hasnain et al [14], Modak et al [15], Sharma and Gautam [16].…”

A field experiment was conducted in sandy loam soils of Agricultural Research Station, Karimnagar during Rabi, 2022 in a split-plot design with three replications. Main plots includes three tillage practices viz., Zero tillage, Reduced tillage and Conventional tillage and sub plots includes three nitrogen levels viz., 75 %N, 100%N and 125%N. The results revealed that, maize cultivation under conventional tillage recorded significantly higher grain yield (8324 kg ha-1) which is statistically on par with reduced tillage treatment (7775 kg ha-1). In turn reduced tillage was statistically comparable to zero-tillage treatment (7353kg ha-1). Among different nitrogen levels examined, maize sown with 125% N application achieved significantly highest grain yield (8055 kg ha-1). This yield was statistically comparable to grain yield observed with 100% N application (7896 kg ha-1). While, significantly lowest grain yield (7501 kg ha-1) was recorded with 75% N application. Significantly highest grain yield in conventional tillage which is statistically on par with reduced tillage and among nitrogen levels, highest grain yield with 125%N which is on par with 100% N may attributed to increase in crop growth parameters viz., plant height, leaf area index and higher yield attributes viz., cob length and diameter, kernel rows number. The study concludes that maize cultivation with conventional tillage or reduced tillage results in higher grain yield. Concerning different nitrogen levels, higher grain and economic yield was obtained with 100% N application.

“…ha -1 was only 80.0 and 54.9 per cent over weedy check, respectively. Similar results were reported by Sharma et al (2016) and Jadon et al (2019). Oil content in soybean seed was not significantly influenced by different weed management treatments.…”

“…Results indicated that a significant decrease in total N, P and K depletion by weeds were recorded with all weed control treatments compared to weedy check. Lowest N, P and K uptake by weeds with two hand-weedings was reported by Sharma et al 2016. The minimum N, P and K depletion (1.3, 0.2 & 1.0 kg ha -1 , respectively) at 30 and 60 DAS was recorded under two hand weeding at 20 & 40 DAS.…”

“…Soybean is a rainy season crop and it faces severe crop weed competition during active phase of growth. The initial slow growth of soybean with lateral spread, offers severe infestation of a large number of weeds which reduces the yield to an extent of 31 to 84% (Kachroo et al 2003;Sharma et al 2016). Although weeds pose problems during the entire crop period but maintaining weed free condition during critical period (first 45 days after sowing) is very much essential (Hosmath 2014;Jadon et al 2019).…”

A field experiment was conducted during kharif season of 2021 to study the effect of weed management practices on uptake of nutrients by weed and soybean at Kota (Rajasthan). The results indicated that weeds in soybean depleted the soil fertility by removing 69.2 kg ha-1 N, 12.4 kg ha-1 P and 76.7 kg ha-1 K under unweeded check. All weed management practices reduced weed dry matter and nutrient uptake by weeds at 30 and 60 days after sowing (DAS). Two hand weedings and ready mixture of fomesafen + fluazifop-p-butyl @ 220 g a.i. ha-1 proved significantly superior in reducing weed dry matter and nutrient uptake by weeds at 30 and 60 DAS over rest of the treatments. All weed control measures significantly enhanced seed and straw yield of soybean over weedy check. Two hand weedings and mixture of fomesafen + fluazifop-p-butyl @ 220 g a.i. ha-1 , sodium acifluorfen + clodinafop-propargyl @ 245 g a.i. ha-1 and propaquizafop + imazethapyr @125 g a.i. ha-1 as post emergence (PoE) were at par and were found to be significantly superior over rest of the treatments in enhancing seed and straw yield. Ready mix application of fomesafen + fluazifop-p-butyl @ 220 g a.i. ha-1 , propaquizafop + imazethapyr @ 125 g a.i. ha-1 and sodium acifluorfen + clodinafop-propargyl @ 245 g a.i. ha-1 (PoE) significantly reduced the NPK uptake by total weeds and significantly improved nutrient uptake by soybean and consequently resulted higher seed yields.

“…Therefore, chemical herbicides are being used immensely to protect the crop from weed flora. Simialr finding were also made in line with those of Sharma et al (2016) [18] and Brar (2018) [5] . Application of pendimethalin alone or its ready mixture with imazethapyr as pre-emergence spray has performed well in controlling weeds in many leguminous crops.…”
