“…This was owing to efficient utilization of available soil moisture, nutrients and solar energy at all the stages of crop growth and lower weed infestation as also reported by Choudhary et al, (2021). These results are in close conformity with the findings of Kumar and Angadi (2014). The different WMPs significantly affected the yield attributes and yield.…”

“…Upasani et al (2017) also reported non-significant effect of tillage methods in maize -wheat system on dry-matter accumulation of weeds. The total dry-matter of weeds in maize crop was higher in ZT plots than MT and CT practices (Kumar and Angadi, 2014). Weed-management practices significantly influenced the weed dry weight at 30, 60 and 90 DAS (Table 2).…”

A field experiment was conducted during the rainy (kharif) season of 2017 and 2018 at Regional Research and Technology Transfer Station, Bhawanipatna of the Odisha University of Agriculture and Technology, Odisha, to study the effect of tillage and weed-management practices (WMPs) on weed-control efficiency (WCE), yield attributes, yield, economics and energetics of hybrid maize (Zea mays L.). The results revealed the minimum weed dry-matter production (4.9 g/m2 ) in conventional tillage (CT) followed by 5.5 g/m2 dry-matter in minimum tillage (MT) and 5.9 g/m2 in zero tillage (ZT) at 60 days after sowing (DAS). Among the WMPs, hand-weeding (HW) at 20 and 40 DAS and application of atrazine 1.0 kg a.i./ha followed by HW at 40 DAS resulted in significantly less weed dry weight with higher weed-control efficiency (WCE) at all the stages of growth. The CT recorded higher seed yield (4.78 t/ha), followed by MT and ZT. However, HW at 20 and 40 DAS resulted higher seed yield (5.76 t/ha) which was at par with application of atrazine 1.0 kg a.i./ha followed by (fb) HW at 40 DAS (5.07 t/ha). The seed yield in HW and atrazine-applied plots was 146 and 117% higher than the weedy check. Higher energy-use efficiency (EUE) and energy productivity with less specific energy and energy intensiveness were recorded in MT (7.40, 0.50 kg/MJ, 2.24 MJ/kg and 0.300 MJ/`) indicating, efficient energy utilization by MT than ZT and CT. Among WMPs, application of atrazine 1.0 kg a.i./ha fb HW at 40 DAS recorded EUE of 9.56, energy productivity of 0.65 kg/MJ, specific energy of 1.56 MJ/kg and energy intensiveness of 0.294 MJ/`.

“…Treatments N 125 and N 150 in which 125 kg N ha -1 and 150 kg N ha -1 was applied were at par and superior to all other treatments. The higher DMA may be attributed to the fact that mulch helped in controlling the weeds and changed the microclimatic conditions near plant base leading to better growth of roots and more availability of nutrients that helped the plants to maintain higher photosynthetic efficiency and significantly higher number of leaves retained (Kumar and Angadi, 2014). This increase in DMA might be due to the fact that highest nitrogen level produced maximum plant height and number of leaves plant -1 as compared to its lower levels thus resulting in higher DMA Parija (2011) and Zhao et al, (2014).…”

The soil was sandy loam, moderately alkaline in reaction, medium in available K and available P and low in organic carbon and available N. The results showed that soil properties viz., pH and EC were not significantly affected under straw mulching treatments whereas organic carbon slightly improved through straw addition. The availability of macro nutrient (NPK) increase with increase rate of wheat straw mulch. Plant growth parameters, yield as well as nutrient uptake were highest in straw mulch as compared to no mulch treatment. Straw mulch increases the NUE (%) of maize crop. However, with increasing the rate of nitrogen, soil EC was significantly affected. The availability of macro (N, P and K) nutrient increased with increasing the rate of nitrogen fertilizer but 125 kg N ha -1 remain at par with 150 kg N ha -1 . Plant growth parameters, yield as well as nutrient uptake were highest in 150 kg N ha -1 which was at par with 125 kg N ha -1 .So, as by economical analysis @10 t ha -1 straw mulch and 125 kg N ha -1 will more beneficial treatment with highest B:C ratio as compared to other treatment.

“…Mulching practice was also proved effective for controlling the weeds reported by Kumar and Angadi, 2014. A perusal of data presented in Table 3 recorded under weedy check. The better expression of yield attributes in herbicide treated and hand weeded plots might be due to minimum crop weed competition during critical phases of crop growth either manually or chemically, exerts an important regulation function on complex processes of yield formation, due to better availability of growth inputs viz., water, space and nutrients.…”

“…Weed management practices brought down competition and created favourable micro-environment for better establishment, growth and development of maize crop.Weed control treatments also increased CGR, compared to weedy check that facilitated higher photosynthate production and translocation from source to sink, resulting in overall improvement in yield attributing traits and consequently the yields. Kumar and Angadi (2014), Samant et al 2015Teame et al 2017and Patel et al (2018) also observed significant effect of weed control in increasing yield of maize.…”

A field experiment was conducted at Research Farm of Agricultural Research Station, Ummedganj, Kota (Agriculture University, Kota), Rajasthan, India during kharif 2019 to find out the most effective herbicide combination for limiting the menace of weeds in maize. Results showed that density of monocot weeds were observed more than dicot weeds during the experimentation. The prominent weeds were Echinochloa colona, Cyperus rotundus, Digera arvensis, Amaranthus viridis, Acalypha indica and Trianthema portulacastrum etc. caused about 58.3% reduction in grain yield as over two hand weeding at 20 and 40 DAS. In general, grassy weeds were better controlled by herbicides than broad leaves weeds. Among herbicides, maximum weed control efficiency (72.18%) was achieved with application of atrazine 500 g a.i. ha-1 (PE) followed by topramezone 25.2 g a.i. ha-1 at 20-25 DAS (72.18%) which is very close to two hand weeding at 20 and 40 DAS. Furthermore, this treatment also produced higher grain (3496 kg ha-1) and stover yield (6460 kg ha-1) which was at par with atrazine 500 g a.i. ha-1 (PE) followed by tembotrione 120.75 g a.i. ha-1 (20-25 DAS) and atrazine 500 g a.i. ha-1 (PE)+hand weeding 30 DAS with in-situ weeds mulching. Thus, pre-emergence application of atrazine 500 g a.i. ha-1 (PE) followed by topramezone 25.2 g a.i. ha-1 at 20-25 DAS is recommended for better weed control and yield of maize.
