“…Intercropping is a strategy for growing more crops in limited land, taking advantage of the crops' natural growth patterns to effectively match crops that can grow together so as to maximize the cultivation space. Intercropping is an essential practice to obtain high production while maintaining the quality of growing crops (Sullivan 2003; Seran and Brintha 2010;Alemayehu et al 2017). In China, farmers have adopted intercropping systems for several years to increase production and decrease erosion.…”

Purpose A reasonable cultivation pattern is beneficial to maintain soil microbial activity and optimize the structure of the soil microbial community. To determine the effect of tobacco−peanut (Nicotiana tabacum−Arachis hypogaea) relay intercropping on the microbial community structure in soil, we compared the effects of relay intercropping and continuous cropping on the soil bacteria community structure. Methods We collected soil samples from three different cropping patterns and analyzed microbial community structure and diversity using high-throughput sequencing technology. Result The number of operational taxonomic units (OTU) for bacterial species in the soil was maximal under continuous peanut cropping. At the phylum level, the main bacteria identified in soil were Proteobacteria, Actinobacteria, and Acidobacteria, which accounted for approximately 70% of the total. The proportions of Actinobacteria and Firmicutes increased, whereas the proportion of Proteobacteria decreased in soil with tobacco–peanut relay intercropping. Moreover, the proportions of Firmicutes and Proteobacteria among the soil bacteria further shifted over time with tobacco–peanut relay intercropping. At the genus level, the proportions of Bacillus and Lactococcus increased in soil with tobacco–peanut relay intercropping. Conclusion The community structure of soil bacteria differed considerably with tobacco–peanut relay intercropping from that detected under peanut continuous cropping, and the proportions of beneficial bacteria (the phyla Actinobacteria and Firmicutes, and the genera Bacillus and Lactococcus) increased while the proportion of potentially pathogenic bacteria (the genera Variibacter and Burkholderia) decreased. These results provide a basis for adopting tobacco–peanut relay intercropping to improve soil ecology and microorganisms, while making better use of limited cultivable land.

“…In addition, using eucalyptus wood for cooking can help the organic matter supply by replacing the burning of dung and plant residue as fuel [2,52,53]. However, growing such trees can put pressure on groundwater resources that can impact grain crop production systems in the region [54].…”

Agriculture in Africa is adversely affected by the loss of soil fertility. Conservation agriculture (CA) was introduced to curb the loss of soil fertility and water shortages and improve crop productivity. However, information on how CA practices enhance soil quality and nutrients is scarce in the sub-Saharan Africa context. The objective of this study was to investigate the effects of CA and conventional tillage (CT) on soil organic matter and nutrients under irrigated and rainfed vegetable on-farm production systems. During the dry and wet monsoon phases in the northern Ethiopian Highlands, a four-year experiment with CA and CT was carried out on ten vegetable farms under rainfed and irrigated conditions. Although the increase in concentration of organic matter in CA was generally slightly greater than in CT, the difference was not significant. The average organic matter content in the top 30 cm for both treatments increased significantly by 0.5% a−1 from 3% to almost 5%. The increase was not significant for the 30–60 cm depth. The total nitrogen and available phosphorus concentrations increased proportionally to the organic matter content. Consequently, the extended growing season, applying fertilizers and livestock manure, and not removing the crop residue increased the nutrient content in both CA and CT. The increase in CA was slightly greater because the soil was not tilled, and hay was applied as a surface cover. Although CA increased soil fertility, widespread adoption will depend on socioeconomic factors that determine hay availability as a soil cover relative to other competitive uses.

Maize is one of the most important cereal crops of Kashmir Valley where it serves as a source of food, feed, fodder and industrial raw material, providing enormous opportunity for crop diversification, value addition and employment generation. However, the average productivity of maize in Kashmir Valley is quite low (1.5 t ha-1) when compared to the national productivity (2.5 t ha-1). The development, dissemination and adoption of high yielding, early maturity, cold tolerant maize hybrids can serve as the most economical, effective and coherent approach to contribute significantly towards increasing maize production in Kashmir Valley. A single cross hybrid SMH4 (Shalimar Maize Hybrid 4) has been developed to enhance the maize productivity in high altitude agro-ecologies of the Valley. SMH4 possesses very high yield potential of about 7.0-8.2 t ha-1 compared to 2.5-4.0 t ha-1 as realised by the predominantly grown landraces in hilly agro-ecosystems. The hybrid revealed the grain yield superiority of about 23.61% and the stover yield superiority of about 15.77% over the commercial check viz., Shalimar maize Hybrid 1. The variety is resistant to Turcicum leaf blight and common rust, besides showing resistance to stem borers and cut worms. SMH4 has a very good acceptability by farmers for its high yield potential (both grain and fodder), better seedling vigour and early maturity. SMH4 with the traits like cold tolerance and early maturity can play a potential role in enhancing the economy of maize growers under high altitude ecologies of Kashmir Valley. The development, upscaling and mass adoption of SMH4 in temperate agro-ecologies will lead to socio-economic upliftment of small and marginal farmers through increase in production, productivity and farm profitability.
