“…Statistically similar yield was obtained from the application of rice straw mulch. Similar results were observed by De et al (1983), Chen (1996) and Upadhyay and Tiwari (1996) who reported that application of pre-emergence herbicide produced the highest grain yield in wheat than hand weeding. The authors opined that plant absorbed soil moisture as vaporized forms but there was no enough facilities to vaporize the soil moisture in control treatment (no mulch) whereas, mulching treatments suppressed the weed growth and conserved available soil moisture and vaporized the moisture for absorption by the plants.…”

Weed management in a sustainable way is the ultimate target of Agronomists to maximize crop yield per unit area. To develop a sustainable weed management technique, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to study the effect of different weed management techniques on the performance of wheat cultivars. The experiment comprised three wheat cultivars; viz. BARI Gom-28, BARI Gom-29 and BARI Gom-30 and five weed management techniques namely, no weeding (W0), two hand weedings (HW) at 20 DAS and 40 DAS (W1), use of rice straw mulch @ 6 t ha–1 (W2), use of pre emergence herbicide Panida @ 1 L ha–1 (W3) and use of pre emergence herbicide + one hand weeding (HW) at 40 DAS (W4). The experiment was laid out in a split-plot design with three replications. The experimental plots were infested by different weed species. Annual weeds were outnumbered than perennial and constitute 84.74% against 15.26%, respectively. Among them, the five most dominant weed species based on the importance value in descending order were Polygonum orientale>Chenopodium album >Cynodon dactylon>Sonchus arvensis>Cyperus rotundus and rest of the weed species represent 8.94%. Wheat cultivar BARI Gom-29 produced the highest grain yield (3.44 t ha–1). The highest grain yield (3.29 t ha-1) was obtained from the application of pre emergence herbicide Panida @ 1 L ha–1. But in case of interaction BARI Gom-29 in combination with use of rice straw mulch @ 6 t ha-1 produced the highest grain yield (4.36 t ha–1). The highest grain yield obtained due to highest number of total and effective tillers hill-1 and highest number of grains spike-1 in BARI Gom-29 with application of rice straw mulch @ 6 t ha–1. From the results of the study it may be concluded that BARI Gom-29 with application of rice straw mulch @ 6 t ha–1 technique appears to be the promising technology in controlling weeds as well as obtaining higher grain yield of wheat.

“…Within irrigation levels, mulch significantly increased yields only on Levels 4 to 6. In earlier studies grain and dry matter yields were greater on mulch than on bare plots for com (Lal, 1974;Olson and Horton, 1975), wheat (Greb et al, 1970;Rajat De et al, 1983), and sorghum (Unger, 1978;Raghavalu and Singh, 1982). No results for mulch effect on bean have been reported.…”

Mulch (crop residue) bas been reported to increase soil water stor. age and crop yield, and to reduce soil water stress undt'r some conditions. However, few studies have bad irrigatlom., and thus evapotranspiration (ET), as a variable where soil water was controlled. Therefore, a study was conducted to evaluate the effect of mulch on ET, bean yield (Phaseolus vulgaris L.), and water use efficiency (WUE), under a wide range of irrigation levels. Treatments were two cultivars (Viva-Pink and Red-63), two mulch rates (bare, and 7.0 Mg ba -• of wheat straw), and six irrigation levds (from 0.0 to 288 mm) for 2 yr. Different irrigation levels were a4:bieved by a line source sprinkler. Evapotranspiration was estimated from measurements of irrigation, precipitation, soil water depleti•>n, and estimated drainage. Transpiration (Tr) was estimated from a function of relative yield and relative ET. Dry matter and seed yieLds were significantly greater for mulched than for bare plots. Muldted plots bad a higher WUE (yield/ET) than did bare plots for a given irrigation level but increased as irrigation level increased. Seasonal diffe1rences in ET between bare and mulched plots were smaU. The yield-E1t relation for mulch was linear but was distinctly different from bare str bare plots, indicating that not all of the water saved went to Tr.

Understanding the combination of conservation tillage and straw mulching on water utilization is important for developing water management strategies in arid and semiarid areas. Few studies have investigated the effects of different tillage treatments on precipitation efficiency in winter wheat (Triticum aestivum L.)‐summer maize (Zea mays L.) cropping systems. A 3‐year field experiment with five treatments, that is, conventional tillage (CT), no‐tillage, no‐tillage with straw mulching (NT + S), subsoiling tillage, and subsoiling tillage with straw mulching (ST + S), was conducted. The objective was to investigate how conservation tillage with straw mulching affected soil water storage (SWC), precipitation storage efficiency (PSE), water consumption, grain yield, water use efficiency (WUE), and precipitation use efficiency (PUE) in a winter wheat‐summer maize cropping system. The results indicated that the ST + S treatment increased SWC by 10.1% and 8.3% in 2014–2015 and 2015–2016, respectively. The average PSE over the 3 years under the ST + S treatment was significantly higher, by 9.1% and 6.6%, than that under the CT treatment during the respective wheat and maize seasons. Compared with CT, the average annual yield under the NT + S treatment and ST + S treatment increased by 8.5% and 14.4%, respectively. In the winter wheat‐summer maize system, the NT + S and ST + S treatments significantly increased the annual WUE and PUE. The annual average PUE under the ST + S treatment was significantly higher, by 14.1%, than that under CT over the 3 years. Therefore, the ST + S treatment was more beneficial than the other treatments for increasing yield, WUE and PUE in sandy loam soil on the North China Plain.
