“…In our study, the alternative tillage plus rice residue retention either partially or fully increased the grain yield of maize. Our results agree with [37] who concluded that, compared with full straw removal, 50% straw retention increased grain yield of maize by 32%, and with [41] who also reported higher maize yields under ZT with rice straw retention. Our study also showed significantly higher mungbean yield with full residue retention compared with no retention.…”

Farmers’ conventional tillage (CT) and residue removal practices in rice-maize systems in South Asia’s Eastern Gangetic Plain (EGP) are input-intensive, costly and soil degradative. We conducted a rice-maize-mungbean (R-M-MB) system experiment with six tillage and three residue management treatments in Bangladesh representing the EGP. Maize yields were significantly (p≤0.05) higher under permanent (PB) or fresh (FB) beds and strip tillage (ST) than CT but no differences in mungbean yields. Rice yields under PB, FB and CT were similar, but significantly higher than under zero or minimum tillage and ST. Yields of all crops increased significantly (p≤0.05) with residue retention compared to no retention. Total system productivity was highest under PB followed by FB and ST. Compared with CT, gross margins in PB, FB and ST increased by 18, 13 and 11%, and soil organic matter (SOM) and total N contents across tillage treatments increased by 11-16% and 12-24%, respectively. After three years, SOM and total N and available P and S contents increased significantly (p≤0.05) by residue retention. Results demonstrate the potential of PB, FB and ST with residue retention, for improving the productivity, profitability and soil health under R-M-MB systems in Bangladesh and similar soils in the EGP.

“…The suppression of weed biomass due to the rice straw is probably due to little transmission or no transmission of solar radiation through residue [22]. Similar result was obtained by [23] in quality protein maize (QPM) due to rice straw. [24] reported that atrazine (0.75 kg/ha) as preemergence and then followed by 2, 4-D (1 kg/ha) as postemergence at 30 DAS recorded significant less seed bank of weed over mechanical weeding.…”

In order to find out the alternative methods for the weed management in spring maize (Zea mays L.) in Terai Nepal, a study was carried out in conservation agriculture under maize-rice cropping system in Rampur, Nepal during 2013. The weeds number and dry weight were compared in tillage methods viz. conventional and no tillage; residue management viz. residue kept and removed; fertilizer doses viz. research recommended doses and farmer dose; and weed management viz. herbicide use and manual weeding. No tillage, residue kept and atrazine applied @ 1.5 kg a.i ha-1 as pre-emergence had significantly lower number and lower dry weight of grasses and broadleaf weeds as compared to conventional tillage, residue removed and manual weeding at an interval of one month. While the number and dry weight of sedges was not significantly influenced by tillage, residue and fertilizer management. Manual weeding had significantly less number and weight of sedges over atrazine use. The total number and dry weight of weeds were less in no tillage, residue retention and atrazine use over the conventional tillage, residue removed and manual weeding. It is concluded that no tillage, residue retention and atrazine use can be the alternative technologies for weed management.

“…Similarly, research dose of fertilizer had significantly (p≤0.01) earlier days to silking in comparison with farmer dose of fertilizer respectively (Table 1). Khan and Parvej (2010) reported significantly earlier silking in quality protein maize (QPM) when rice straw was used as mulch and significantly earlier silking as the nitrogen rate increases from 120 and 160 to 200 kg ha -1 (Dawadi and Sah, 2012). Similarly, earlier silking was observed with high dose of phosphorus (Amanullah et al, 2010) and potash (Asif et al, 2007).…”

“…But weed management factor did not influence significantly on the physiological maturity of maize (Table 1). Khan and Parvej (2010) reported significantly earlier days to maturity in tilled condition as compared with no tilled condition in QPM. BK et al (2013) reported that the residue retained treatment had significantly longer days to maturity than residue removed treatment.…”

“…Similarly, residue retained level and research dose of fertilizer had significantly (p≤0.01) longer ear length in comparison with residue removed and farmer dose of fertilizer respectively. Ear length of QPM increased significantly in no tillage and residue retained in comparison with conventional tillage and residue removed (Khan and Parvej, 2010). Ear length of maize increased significantly with increasing nitrogen levels (Onasanya et al, 2009) and phosphorus level (Amanullah et al, 2010).…”

With the aim of developing crop management technologies that reduce the yield gap of maize (Zea mays L.) in Nepal, a study was carried-out to determine whether the grain yield of maize could be manipulated through tillage, residue, and nutrient and weed management practices. The effect of tillage (conventional and no tillage), residue (residue retained and residue removed), fertilizer (recommended doses of fertilizer and farmers' doses of fertilizer) and weed management practices (herbicide use and manual weeding) on phenology and grain yield of maize were investigated under maize-rice cropping system in Rampur, Nepal during 2013. The experimental results revealed that no tillage had significant effect on grain yield (6.64 Mg ha-1) and phenological parameters like days to silking, physiological maturity and seed fill duration. Similarly, residue retained treatment had significant effect on grain yield (7.02 Mg ha-1) and phenological parameters. Research dose of fertilizer had significant effect on phenological parameters and grain yield (8.42 Mg ha-1). However, weed management factor did not influence significantly on grain yield and phenological parameters. The grain yield increased in no tillage by 23.19% over conventional tillage, residue retained by 39.84% over residue removed, recommended doses of fertilizer by 132.60% over farmer dose of fertilizer. Thus, no tillage, residue retention, recommended doses of fertilizer and use of herbicide for weed management can be alternative technologies for sustainable higher grain yield.
