“…Based on the agriculture input and output evaluation, the data presented herein form the present study indicated that intercropping systems increased the economic benefit compared with sole cropping systems, and these results were in accord with previous studies (Chapagain et al., 2018; Qian et al., 2018). The net incomes and benefit: cost ratios of the maize‐based intercropping were all higher than those of the sole cropping (Table 4).…”

“…The improvement of crop productivity could be attributed to the optimized intercrop canopy and root structure, higher uptake and utilization of resources, and substitution of planting crops which incorporated higher energy (Knörzer et al, 2009). Based on the agriculture input and output evaluation, the data presented herein form the present study indicated that intercropping systems increased the economic benefit compared with sole cropping systems, and these results were in accord with previous studies (Chapagain et al, 2018;Qian et al, 2018).

Global agriculture is facing multiple challenges to meet the food demands, optimize resource utilization, and mitigate the climate change. A field study, combined with the life cycle assessment (LCA), was conducted to select the effective and sustainable cropping systems in northwestern China. The study compared four maize‐based intercropping and corresponding monoculture systems on crop yield, evapotranspiration (ET), water use efficiency (WUE), profitability, and carbon footprint (CF). Maize/wheat intercropping had the highest energy yield (532.5 GJ/ha, on average) and maize equivalent energy yield (MEEY) (522.3 G/ha, on average), followed by those from the maize/rape intercropping system, and the lowest by the sole potato system. The WUE of maize equivalent energy yield (WUEMEEY) was the highest (1.06 GJ ha−1 mm−1) for sole rape system, followed by those for the maize/wheat and maize/rape intercropping systems. Maize/potato intercropping had the highest benefit: cost ratio at 3.30, followed by those for the maize/wheat intercropping (2.58), sole potato (2.57), and maize/rape intercropping (2.53). Lower CF and higher net ecosystem economic budget (NEEB) were observed in maize‐based intercropping systems. The maize/wheat intercropping system had the lowest CF per maize equivalent energy yield (CFm) (10.7 kg CO2‐eq GJ−1 year−1), and the maize/potato intercropping system had the lowest CF per unit economic output (CFe) (0.14 kg CO2‐eq US$−1 year−1), and the highest NEEB (7,352.8 US$/ha). The data presented indicate that maize‐based intercropping system may be a viable practice for the synthesized goals of higher productivity and profitability while lesser environmental footprint in a water‐scarce region of northwest China.

“…However, in Dhading, all the test farms were located in the drier Bari lands in both production years. Wetter Khet lands are annually used for lowland rice production by farmers, where they apply significant amounts of farm yard manure and inorganic N fertilizer (rice is the main staple crop in Nepal) [57]. Furthermore, the wetter Khet lands retain more moisture in the soil, whereas the drier Bari lands retain less (due to the increased sloping of the terraces).…”

Studies have shown the potential of rhizobia and associated micronutrients to enhance symbiotic nitrogen fixation in legumes. Tens of millions of smallholder farmers, however, farm on mountain hillsides in highly variable soil and microenvironments, with different crop rotations, inputs and cultural practices. Here, on the terraces of the Nepalese Himalayas, we evaluated rhizobium inoculants (local, exotic), micronutrients (molybdenum, boron) and their combinations as technologies for smallholder farmers under highly variable microenvironments and traditional practices. The study was conducted as a series of participatory on-farm trials with 39 terrace farmers in two mid-hill districts of Nepal (Dhading, Kaski) from 2015 to 2017. Plots were measured for relevant agronomic traits. As expected, when comparing treatment plots with adjacent control plots within each farm, the results demonstrated tremendous farm-to-farm variability for nodulation, vegetative biomass, shoot nitrogen content, grain yield, and grain N content. Despite the variation observed, the data showed that the number of farms that showed yield increases from the rhizobium interventions, compared to those that suffered yield losses, was generally 2:1. We discuss potential experimental and socio-agronomic reasons for the variable results, including rainfall, which appeared critical. The results demonstrate the promise of rhizobium interventions for hillside smallholder farmers, even in a highly variable context.

“…Uma combinação adequada de sucessão e consórcio de culturas pode trazer melhores rendimentos do que monoculturas (CHAPAGAIN et al, 2018;ANDRADE et al, 2017). Nos Pampas argentinos, vários experimentos indicam que a repetição de safras de cereais reduz suas produtividades, enquanto sucessões de consórcios bem equilibrados 4 , que incluem leguminosas, resultaram nas mais altas produtividades das culturas de cereais (ANDRADE et al, 2017).…”

Uma forma de reduzir incertezas da produção e obter economia de escopo é por meio do emprego da diversificação de atividades, que pode ser entendida por diferentes conceitos e abordagens. O presente trabalho tem como objetivo apresentar arcabouço teórico e empírico da diversificação agropecuária no Brasil, utilizando abordagens socioeconômica e agronômica. Além disso, apresenta-se as possíveis formas de diversificação agropecuária, ressaltando sua importância ambiental e econômica. Para isso, apresenta-se a evolução da produção agropecuária municipal a partir de dois índices: Shannon e Simpson, no período1987-2017. Os resultados revelam tendência à especialização de culturas, especialmente na região Centro-Oeste. No entanto, a produção agropecuária municipal ainda se encontra na categoria “diversificada” nesse período. Os estabelecimentos acima de 1000 hectares têm uma relação negativa com a diversificação agropecuária, contrária aos estabelecimentos entre 0 a 50 hectares da região Sul e Centro-Oeste.
