“…Increasing crop-rotation diversity offers a number of benefits to an integrated crops–livestock production system, including greater yield resiliency and enhanced yield increases compared to a monoculture or two-crop rotation ( Bowles et al, 2020 ). Diversified crop rotations, when combined with livestock production, also reduce month-to-month variation in labor requirements compared to a corn–soybean rotation with livestock ( Poffenbarger et al, 2017 ).…”

Crossbred beef steers with a high percentage of Angus ancestry [n = 240, initial shrunk bodyweight (BW), 404 ± 18.5 kg] were used in a 117-d feedlot experiment to evaluate the effect of hybrid rye (KWS Cereals USA, LLC, Champaign, IL; Rye) as a replacement for dry-rolled corn (DRC) on growth performance, carcass traits, and comparative net energy (NE) value in diets fed to finishing steers. Rye from a single hybrid (KWS Bono) with an ergot alkaloid concentration of 392 ppb was processed with a roller mill to a processing index (PI) of 78.8 ± 2.29. Four treatments were used in a completely randomized design (n = 6 pens/treatment, 10 steers/pen) where DRC (PI = 86.9 ± 4.19) was replaced by varying proportions of rye [DRC:Rye, DM Basis (60:0), (40:20), (20:40), and (0:60)]. Liver abscess scores and carcass characteristics were collected at the abattoir. Carcass-adjusted performance was calculated from HCW/0.625. Performance-adjusted NE was calculated using carcass-adjusted ADG, DMI, and mean equivalent shrunk BW with the comparative NE values for rye calculated using the replacement technique. Data were analyzed using the GLIMMIX procedure of SAS 9.4 (SAS Inst. Inc., Cary, NC) with pen as the experimental unit. Treatment effects were tested using linear and quadratic contrasts as well as between diets with and without Rye. Replacing DRC with Rye linearly decreased (P ≤ 0.01) carcass-adjusted final BW, ADG, DMI, and G:F. Feeding rye linearly decreased HCW and LM area (P ≤ 0.04). Distributions of liver scores and USDA grades for quality and yield were unaffected by treatment (P ≥ 0.09). Estimated replacement NEm and NEg values for rye when included at 60% of diet DM were 1.90 and 1.25 Mcal/kg, respectively. Rye can be a suitable feed ingredient in finishing diets for feedlot steers. Estimated replacement values of Rye when fed at 60% of diet DM closely agreed with current tabular standards, but when included at 20% of diet DM estimated NEm and NEg values of Rye were increased 9.5 and 12.8%, respectively. Net energy value of hybrid rye for gain is approximately 84% compared to DRC, thus, complete replacement of DRC with rye depressed DMI, ADG, G:F, and carcass weight.

“…While numerous species performing a similar function in an agroecosystem could be considered redundant at a given time, they are unlikely to be redundant when taking a longer-term perspective and particularly under an increasingly changing climate. For instance, several studies have highlighted the positive contribution of crop diversity to the mean and variance in agricultural yields (Lin 2011;Gaudin et al 2015;Bowles et al 2020) and in farm income (D'Annolfo et al 2017;van der Ploeg et al 2019). Furthermore, recent global research shows that countries with higher crop diversity generally support more agricultural employment (Garibaldi and Perez-Mendez 2019).…”

“…Agroecological transitions should equally enhance socio-economic resilience. Through diversification and integration, producers reduce their vulnerability should a single crop, livestock species or other commodity fail (Dumont et al 2013;Bellon et al 2020;Bowles et al 2020). By reducing dependence on external inputs through enhanced reliance on biological processes underpinning soil health and the regulation of pests and diseases (Tscharntke et al 2005;Barrios et al 2012b;Dumont et al 2013), agroecology can reduce producers' vulnerability to economic risk (Schipanski et al 2016;Feliciano 2019).…”

The magnitude and urgency of the challenges facing agriculture and food systems demand profound modifications in different aspects of human activity to achieve real transformative change and sustainability. Recognizing that the inherent complexity of achieving sustainability is commonly seen as a deterrent to decision-making, the Food and Agriculture Organization of the United Nations (FAO) has approved the 10 Elements of Agroecology as an analytical framework to support the design of differentiated paths for agriculture and food systems transformation, hence facilitating improved decision-making by policymakers, practitioners and other stakeholders in differing contexts at a range of levels on a number of scales. Biodiversity, consumers, education and governance are identified as promising entry points to build a structured process using visual narratives that rely on the 10 Elements of Agroecology to graphically dissect prospective social-ecological transition trajectories. We illustrate such applications with examples from agroforestry worldwide, public food procurement in Brazil and the United States of America, and agroecology education vis-à-vis secure access to land in Senegal. Nexus approaches are used to highlight and examine salient interactions among different sectors and entry points, and to develop visual narratives describing plausible theories of transformative change towards sustainable agriculture and food systems.

“…nutrient and water and appropriate crop sequences could maximize the crop yield. Increase in crop yield is associated with crop rotation is known as rotation effect while monoculture practice significantly decreased the crop yield [106]. There is an effective management practice of legumes and nonleguminous crop which linearly enhanced the crop yield and other yield components.…”

Abiotic Stress in Plants

Drought stress is the most prominent limiting factor and abiotic stress that manipulates the physiological pathway, biochemical traits and hence negatively affects wheat crop productivity. The global nitrogen (N) recovery indicated that about two-fifths of N inputs are lost in the ecosystems through emission, denitrification, gaseous loss, leaching, surface runoff and volatilization etc. Farmers are using higher rates of N to harvest maximum yield but about 50–60% of applied N to crop field is not utilized by the plants and are lost to environment causing environmental pollution. These deleterious environmental consequences need to be reduced by efficient management of N and/or water. N-availability is often regulated by soil water; hence crop is experiencing N- and water-limitation simultaneously. There is great impetus to optimize their uptake through interconnectedness of water and N for yield determination of wheat because of the water scarcity and N losses. It is further advocate that there is need to investigate the intricate role of economizing N rate and water simultaneously for wheat crop growth, yield and backing quality may be beneficial to be investigate.
