Global population will hit 9.6 billion people by 2050 [108] and will face global challenges among which achieving food security, lowering the risk of climate change by reducing the net release of greenhouse gases into the atmosphere and meeting the increasing demand for energy are the most critical ones. In particular, the impact of climate change and associated biotic and abiotic stresses to which crop systems will be increasingly exposed pose serious implications for global food production [119].

To meet these challenges, a policy framework needs to be developed in which the sustainability of production/consumption patterns becomes central. In this context, food legumes and legume-inclusive production systems can play important roles by delivering multiple services in line with sustainability principles. Indeed, legumes play central roles [112]: (1) at food-system level, both for human and animal consumption, as a source of plant proteins and with an increasingly importance in improving humans health [106]; (2) at production-system level, due to the capacity to fix atmospheric nitrogen making them potentially highly suitable for inclusion in low-input cropping systems, and due to their role in mitigating greenhouse gases emissions [53]; and (3) at cropping-system levels, as diversification crops in agroecosystems based on few major species, breaking the cycles of pests and diseases and contributing to balance the deficit in plant protein production in many areas of the world, including Europe [43, 48, 72, 78, 116].

Leguminosae family comprises 800 genera and 20,000 species [54] and represents the third largest family of flowering plants. Some legumes are considered weeds of cereal crops, while others are major grain crops; these latter species are known as grain legumes, or pulses,Footnote 1 and represent the focus of this review. For some of these species, the trends for word acreage and yield are available, as reported in Table 1.

Intercropping systems consist in simultaneous growth of two or more crop species on the same area and at the same time [13]. Intercropping is widely used in developing countries or in low-input and low-yield farming systems [73]. Despite several recognized beneficial aspects of intercropping such as better pest control [60], competitive yields with reduced inputs [70, 107], pollution mitigation [63], more stable aggregate food or forage yields per unit area [100], there are a number of constrains that make intercropping not common in modern agriculture, such as example the request of a single and standardized product and the suitability for mechanization or use of other inputs as a prerogative in intensive farming system [13]. It is therefore necessary to optimize intercropping systems to enhance resource-use efficiency and crop yield simultaneously [55], while also promoting multiple ecosystem services (see also [13]). Most recent research has focalized on the potential of intercropping in sustainable productions and in particular on grain legumes that can fix N2 through biological mechanisms (BNF). Indeed, legumes are pivotal in many intercropping systems, and of the top 10 most frequently used intercrop species listed by Hauggaard-Nielsen and Jensen [32], seven are legumes One of the basic spatial arrangements used in intercropping is strip intercropping, in which two or more crops grow together in strips wide enough to permit separate crop production using inputs but close enough for the crops to interact. The current challenge is how to determine an optimal intercropping width to maximise the resources use efficiency and, consequently, the crop productivity. In a maize-bean strip intercropping, Mahallati et al. [65] suggested that strip width of 2 and 3 rows was superior compared with monoculture and other strip intercropping combinations in terms of radiation absorption, radiation use efficiency and biological yields of both species, also allowing to an improve of total land productivity and land equivalent ratio (1.39 and 1.37). Gao et al. [26] showed a total yield increase of 65 and 71% in a system of 1 and 2 rows of maize (planted at a higher density in intercropping) alternated with 3 rows of soybean compared with both crops grown as monoculture. However, Liu et al. [59] showed a reduction in the photosynthetically active radiation and R:FR ratio at the top of soybean canopy intercropped with maize - under two intercropping patterns: 1 row of maize with 1 row of soybean; 2 rows of maize with 2 rows of soybean - leading to increased internode lengths, plant height and specific leaf area (SLA), but reduced branching of soybean plants. In order to gain sufficient light in the most shaded border rows of the neighbouring, shorter crops, efforts could be addressed to (i) the selection of highly productive maize cultivars with reduced canopy height and LAI; (ii) the increase of the strip width under a higher fraction of direct PAR; (iii) the selection of crops and cultivars suitable under the shade levels that likely occur in strip-intercropping systems with maize [71].

The expansion of ecological-based approaches like conservation agriculture opens opportunities to food legumes to be profitably included in sustainable cropping systems. There are still major challenges for conservation agriculture that need to be overcome, including the development of effective methods for weed control (see also [92]) that can avoid the use of herbicides or tillage. Overall conservation agriculture is an environmentally sustainable production system that may boost the incorporation of grain legumes within large and small-scale farming.

Legumes are emphasized by the U.S. Dietary Guidelines (about 3 cups a week) and the DASH Eating Plan of the National Heart, Lung, and Blood Institute (4-5 half-cup servings a week). [2] The Food and Agriculture Organization (FAO) of the United Nations declared the International Year of Pulses in 2016, focusing on the contribution of pulses in food production and nutritional diversity to help eradicate hunger and malnutrition. [3]

Legumes have a range of characteristics that make them a relatively sustainable crop. For example, legumes release up to seven times less greenhouse gas emissions per area compared to other crops, and can sequester carbon in soils. They can also make their own nitrogen from the atmosphere, thus reducing the application of nitrogen fertilizers. This leaves nitrogen-rich residues in the soil after harvesting; a benefit for the next crop planted in its place. [1] According to the FAO, drought-resistant species of legumes can be of particular benefit to dry environments where food security is often a challenge. They can also help minimize food waste, since pulses can be dried and stored for relatively long periods of time without losing their nutritional value. [15]

Choose a career in the high-demand sector of crop and livestock production, management and logistics or in precision and smart agriculture. Explore opportunities in grain buying, marketing and transport, elevator or grain terminal operation, input sales, implement sales and marketing or agricultural research. Become an agricultural specialist in banking, finance or crop insurance.

Africa produces a diversity of crops including cereal, pulse, oilseed, root, and tuber species (Table 1), but contributes less than a quarter of the world production of root and tuber crops (Ngopya, 2003). In East Africa, bananas (especially cooking bananas) are an extremely important crop. In Uganda, for example, bananas serve as the largest only source of calories. Even though crop production is mostly for subsistence needs, there is tremendous business potential in local and international markets.

Breeding efforts only address the first two constraints of biotic factors and abiotic factors. The ability to store a crop after harvest is also affected by biotic and abiotic factors. In order to improve food security and provide income to farmers, continuous efforts by plant breeders are needed to increase production per unit area of land while maintaining crop quality.

Asexual reproduction generates individuals that are genetically identical to the mother parent plant and are referred to as clones. The two main forms of asexual reproduction/propagation are vegetative and apomictic. Vegetative propagation is the creation of clones from stem cuttings, suckers (similar to tillers), tubers, runners (stolons), rhizomes, bulbs, scions, and other plant parts. Cassava, sweet potato, and sugarcane are propagated via stem cuttings. Bananas are typically propagated by suckers, while potatoes are propagated by tubers. Elephant grass (Napier grass, Pennisetum purpureum) is propagated by rhizomes, sets (suckers), and stem cuttings. Apomictic reproduction is the asexual propagation of a plant via clonal seeds formed by one of several means that either bypass meiosis or result in a failure of meiosis. Examples of apomictic crops include Citrus and many perennial forage species.

Breeders must understand the reproductive system of the crop they are working on to make knowledgeable decisions about which breeding methods (i.e., crossing techniques, population maintenance, isolation distances, line and population development) are suitable and which type of cultivar (i.e., hybrid, pure-line, synthetic, clone) is appropriate. The modes of pollination and reproduction of some major crops are shown in Table 2. More information on the reproductive systems of crops is found in Allard (1960; pp. 40-41).
