“…These results are similar to those of Pishgar Komleh et al [27], who found that greater yield led to greater benefit to cost ratio [27]. Zhao et al [21] showed that straw mulching decreased greenhouse gas emission intensity by 47% and 40%, and net economic return under straw mulching increased by 13% and 27%, compared to plastic mulching and ridge-furrow plastic mulching plus furrow seeding treatments, respectively [21]. Adding a high concentration maize silage to feed can improve the economic benefits, sustainability, and carrying capacity of livestock production [85][86][87].…”

Straw strip mulching in maize (Zea mays L.) production is showing a positive effect with the increasing negative effects coming from crop straw and plastic film residues. Therefore, it is imperative to develop comprehensive utilization of straw, and promote the green development of agriculture in rainfed regions. A dryland field experiment was conducted in semiarid northwestern China in 2017 and 2018 and included three treatments: maize straw strip mulching with alternating strips of mulched and non-mulched soil (MSSM), and double ridge-furrow fully mulched soil with white or black plastic film (DRWP or DRBP, respectively). The results show that the interaction between mulching treatment and year significantly influenced maize silage yield, grain yield, biomass yield, aboveground plant water content at silage maize harvest stage, ears ha−1, kernels ear−1, and thousand kernel weight (p < 0.001, p = 0.002, p < 0.001, p < 0.001, p < 0.001, p < 0.001, p < 0.001, and p < 0.001, respectively). For silage, maize growth under straw strip mulching was greater than that of the double ridge mulching system. Silage yield of MSSM was significantly higher than that of DRWP and DRBP, but maize grain and biomass yields under MSSM were significantly lower those under DRWP and DRBP in 2017 and 2018. Compared with the double ridge mulching system, net economic return from silage with MSSM was significantly increased by 28.31% and 20.85% in 2017 and 2018, respectively, and net economic return from grain was 6.67% lower in 2017 and 2.34% higher in 2018. The MSSM treatment exhibited water-temperature coupling; the MSSM treatment significantly reduced soil temperature in the 0–25 cm soil layer by 1.23–2.14 °C and increased soil water storage in the 0–200 cm soil layer by 9.75 and 24.10 mm in 2017 and 2018, respectively, thereby delaying growth development of maize by about 13 days. Therefore, straw mulch can replace plastic film mulch and serve as an environmentally friendly cultivation method for maize in semiarid rainfed regions.

“…However, a larger negative of plastic mulching on the soil, air, and environment relates to how it might impact human life in the future [21]. Meanwhile, crop straw residue is on the rise with the increasing demand for food security, and burning has become one of the shortcut ways to deal with straw residue before the new cropping seasons.…”

“…Some studies reported that potato tuber yield might be reduced by light plastic mulch because soil temperature could rise to a level beyond the optimum temperature during part of potato growing period (Baghour, Moreno, Hernández, Castilla, & Romero, 2002). Thus, finding an alternative mulching practice to plastic film mulching should be considered imperative, and straw mulching is one such alternative and has the benefit of being biodegradable and environmentally friendly (Zhao, Liu, Chen, & Wang, 2019).…”

Straw strip mulching affects soil moisture and temperature for potato yield in semiarid regions

Straw mulching is widely used in agriculture to conserve soil water and improve crop productivity. The effects of straw strip mulching and film mulching on dryland soil water storage and temperature, potato (Solanum tuberosum L.) growth and yield, and water use efficiency (WUE) were examined from 2014 to 2015 in the rainfed semi-arid regions of China. Field experiments were conducted with four treatments: (a) alternating strips mulched with maize (Zea mays L.) straw and bare plots with no ridges (SM); (b) alternating large ridges and small furrows with only the ridges mulched with black polyethylene film (PMP); (c) alternating narrows and wide ridges both mulched by black polyethylene film (PMF), and (d) traditional bare land planting without mulching (CK). The results indicated that film mulching had positive effects on soil water storage at the early stage of potato growth, while the SM significantly improved soil water storage at the late growth stage. Soil water storage (0-2-m depth) was 11.3-35.4 mm greater with the SM than that with the other treatments, especially during the tuber bulking in summer drought period. Compared with the CK, the SM significantly decreased soil temperature by 0.8-1.4 • C, and increased potato yield by 10.5-34.2%, WUE by 8.9-29.8%, and commodity rate by 14.7-38.8%. Compared with the PMP and PMF, the SM increased potato yield by 4.6-12.9 and 3.4-9.3%, respectively. This might be contributed to increased soil moisture and lower soil temperature, which promoted potato growth, yield, and commodity rates.Abbreviations: CK, traditional bare land planting without mulching; ET, evapotranspiration; PMF, narrow and wide ridges mulched by black polyethylene film; PMP, large ridges and small furrows only ridges mulched with black polyethylene film; SM, straw strip mulching; SWS, soil water storage; WUE, water use efficiency.

“…A cobertura morta é uma prática agronômica de resiliência agrícola adotada no manejo do solo em todo o mundo, principalmente em regiões áridas e semiáridas, pois proporciona melhoria na produção agrícola garantindo uma maior segurança alimentar (Alves et al, 2018;Shahzad et al, 2019;Hu et al, 2020). Seu material pode ser orgânico, a exemplo da palhada de milho, capim, restolhos de culturas agrícolas, entre outros, ou também, materiais sintéticos, como filme plástico, sendo sua escolha dependente da finalidade (Zhao et al, 2019). É amplamente adotada, pois possui características positivas tanto para a planta, assim como para o solo, sobretudo o de material orgânico, pois permite um maior aumento da infiltração da água no solo, reduzindo o escoamento superficial, e maior armazenamento, por causa da menor evaporação (Gao et al, 2019;Ibrahim et al, 2020); aumento da estabilidade dos agregados, reduzindo a velocidade do fluxo e a capacidade de transporte dos sedimentos (Rahama, Warrington & Lei, 2019;Yang et al, 2020); menores temperatura na superfície do solo; além de ser um material que proporciona um acréscimo da quantidade de matéria orgânica devido a maior taxa de mineralização proporcionada pelo aumento da microbiota do solo; e, redução do crescimento de plantas invasoras (Ibrahim et al, 2020;Wang et al, 2020a).…”

A baixa disponibilidade de forragem devido à escassez hídrica e o efeito das mudanças climáticas são problemas enfrentados pelos produtores rurais das regiões semiáridas. Para contornar esses efeitos, pesquisas mostram a importância da utilização de espécies que sejam adaptadas às condições ambientais. Dentre essas espécies, a palma forrageira é um importante alimento para dietas de ruminantes, de alta aceitabilidade, rico em energia e alto teor de água, além da sua implantação no campo ser de baixo custo. O milheto é uma outra espécie usada, pois apresenta tolerância aos estresses hídrico e salino, além de ser um alimento útil para suplementação junto com a palma forrageira. O emprego de práticas agrícolas como irrigação, cobertura morta e consorciação pode auxiliar no sistema de produção dessas culturas. Além disso, a aplicação de parâmetros agrometeorológicos são relevantes para garantir o melhor planejamento e a tomada de decisão agrícola. Nesta revisão, objetivou-se abordar práticas agronômicas, análises estatísticas e indicadores agrometeorológicos empregados em pesquisas voltadas às culturas da palma forrageira e do milheto em sistemas de produção. Pesquisas foram feitas nas bases bibliográficas da Scopus, ScienceDirect, Mendeley e Google Scholar. As práticas agrícolas uso mínimo de irrigação, cobertura morta e consorciação são essenciais nos sistemas de cultivo da palma forrageira e do milheto. Em conjunto ao manejo dessas culturas, o uso de indicadores agrometeorológicos atrelados à análise multivariada permite o melhor planejamento e tomada de decisão na produção.
