“…In these systems during the dry season, the availability of dry matter decreases, as well as the levels of crude protein, minerals and some vitamins in forages and as a result productivity is reduced (Murgueitio et al, 2015). Pasture-based systems are likely to be more affected by climate change, due to their dependence on feed quality and availability, where changes in temperature and variations in precipitation are critical factors for production (Rojas-Downing et al, 2017). The use of improved species (grasses and legumes) in mixed production grasslands is an important strategy to increase the resilience of agroecosystems to drought and flooding associated with climate change, relative to native or naturalized plants (Rao et al, 2015).…”

Livestock production in some tropical regions is characterized by the use of naturalized forages in extensive management with low production rates. The use of improved grass-legume associations represents a sustainable intensification opportunity for this type of agroecosystems. The objective was to evaluate the production in establishment of forage associations for grazing systems in the dry tropics of Colombia. In a randomized complete block design with slope as the block factor and experimental units of 2700 m2 with four replications, the agronomic and nutritional quality characteristics of six treatments were compared: Urochloa hybrid cultivar Mulato II, U. brizantha cultivar Toledo and Megathyrsus maximus cultivar Mombasa, established alone or associated with Canavalia brasiliensis, against the control Dichantium aristatum, a naturalized forage of the region. Mulato II, Toledo and Mombasa alone and in association showed greater (p ≤ 0.05) vigour, height, cover and forage production than the control. Mombasa produced 10.7 Mg ha-1 MS (Megagrams of dry matter per hectare), exceeding (p ≤ 0.05) by 74, 53 and 84 % that were recorded in Mulato II, Toledo and control, respectively. C. brasilienses promoted higher productivity in the association with Mulato II and improved nutritional characteristics in the associations with Toledo and Mombasa compared to specific monocultures and the control. The improved grasses alone or associated with C. brasiliensis were a better forage option than Dichantium aristatum. It was concluded that M. maximus and Urochloa hybrid associated with C. brasiliensis are relevant forage options for agroecologically similar regions to the Colombian dry tropics.

“…Agricultural diversification has been widely recognized as one of the major adaptation strategies for sustaining rural livelihoods in the face of climate and other unexpected changes [1][2][3][4]. Crops increase productivity and enhance the stability of household livelihoods (e.g., stable household income and food security) [5] and the ecological services of agroecosystems (e.g., improved soil fertility, agro-biodiversity, and reduced emission of greenhouse gasses) [6].…”

“…Despite ample evidence of the benefits of agricultural diversification (including genetic resources and management practices) to agricultural production [2,3], natural resources and rural livelihoods, farmers' decisions regarding agricultural diversification have not been well understood. Adequate understanding of the social, economic and ecological drivers of smallholders' diversification strategies are the key for rural policy makers and developers to improve agricultural and livelihood resilience in rural areas.…”

Agricultural Livelihood Types and Type-Specific Drivers of Crop Production Diversification: Evidence from Aral Sea Basin Region

et al. 2022

Understanding the factors driving the farmers’ decisions to diversify their crop production is important for management strategies and policies promoting climate-smart agricultural development. Options for diversification and its associated drivers might be shaped by livelihood context, and it remains as a general gap in knowledge. This study aimed to reveal the driving factors behind households’ decisions to diversify their crops in different livelihood contexts. This information could be useful to inform stakeholders on a set of context-fitted options for improving natural resources and rural livelihood resilience to climatic variability and risks. This study applied the Sustainable Livelihood Framework (SLF) to guide surveys and multivariate analyses that identified agricultural livelihood context types at the village level, and also evaluated both the common and type-specific drivers encouraging households to diversify their agricultural production in two rural villages in the Aral Sea region. This study objectively identified three distinct agricultural livelihood types and the main factors differentiating these types from each other. When the total sampled population was analyzed, the results indicated that the agricultural experience of the household heads, levels of education, sources of income, number of cattle and land endowments, and proximity to markets were common and significant drivers in diversifying these households’ crop production. Analyzing the decisions behind diversifying crop production for each agricultural livelihood type revealed type-specific drivers of diversification. The findings suggested that considering both common and type-specific drivers of diversification would allow better understanding of household decisions and provide more insights to develop effective policies promoting climate-smart agriculture through diversification, rather than continuing to use the current “uniform blanket” approach.

“…In particular, beef cattle ( Bos Taurus L.) and horses ( Equus caballus L.) often depend on pasture to provide forage during the growing season. Several grasses are widely used in pastures, and producers select forage species based on yield, persistence, preference, and nutritive value (Rojas‐Downing et al., 2018; Sheaffer et al., 2009).

“…Perennial ryegrass ( Lolium perenne L.; PR) is widely grown in regions of the U.S with milder winters, where it is noted for its high seedling vigor, forage yields, and nutritive value (Collins & Nelson, 2017; Rojas‐Downing et al., 2018; Ribeiro Filho, Delagarde, & Peyraud, 2019 ). In both monoculture and in mixture with white clover ( Trifolium repens L.; WC), PR was highly preferred by cattle and horses (Hunt & Hay, 1990; Olson, Smith, Phillips, & Lawrence, 2016, Smit, Tamminga, & Elgersma, 2006; Allen, Sheaffer, & Martinson, 2013).…”

Yield, persistence, forage nutritive value, and preference of perennial ryegrass under grazing

Perennial ryegrass (PR) is a quality and high yielding forage that tends to lack winter hardiness to persist in the upper Midwest. The objective was to evaluate yield, stand persistence, forage nutritive value, and preference of experimental populations of winter hardy PR grown in monoculture and in mixture with white clover under livestock grazing. Research was conducted in St. Paul and Grand Rapids, MN. Meadow fescue (MF), tall fescue (TF), orchardgrass (OG), a reference PR, and two experimental populations of PR were grazed every 32 days by either horses (St. Paul) or cow-calf pairs (Grand Rapids). Prior to grazing, forage yield and quality samples were collected, and post-grazing, fields were visually assessed for the percentage of forage removal to determine preference. Yields of all PR (6.9 to 7.6 Mg ha −1) were similar, but lower compared to other coolseason grasses (CSG). Persistence was similar among all CSG in St. Paul; however, it was lower for all PR in Grand Rapids compared to other CSG. All PR were highly preferred by both horses (≥74% removal) and cattle (≥70% removal) and were consistently among the highest for crude protein (CP; 200 g kg −1), equine digestible energy (DE; 2.35 Mcal kg −1) and bovine metabolizable energy (ME; 2.6 Mcal kg −1), moderate for nonstructural carbohydrates (NSC; 136 g kg −1), and among the lowest for neutral detergent fiber (NDF; 518 g kg −1). Experimental populations of PR produced forage of high nutritive value, but yield and stand persistence may be less compared to other CSG at some locations. 1 INTRODUCTION Cool-season perennial grasses (CSG) are the foundation of productive pastures in the upper Midwest (Allen, Sheaf
