“…The significantly lower root mass obtained under ZT compared with tilled plots suggested that soil compaction under ZT impeded root development and the growth of the main root axes (Martınez et al, 2008) while conventional tillage increased root penetration (Shirani, Hajabbasi, Afyuni, & Hemmat, 2002). The consistently higher maize root mass observed under MT than under CT and ZT occurred probably because minimum tillage broke the compact soil surface that is often associated with ZT and prevented intense soil perturbation that occurred under CT which could later minimize root growth (Busari & Salako, 2015). This also emphasized the more resilient nature of soil maintained under a minimum tillage system (Lal, 1993) compared with other tillage systems.…”

There is an urgent need to match food production with increasing world population through identification of sustainable land management strategies. However, the struggle to achieve food security should be carried out keeping in mind the soil where the crops are grown and the environment in which the living things survive. Conservation agriculture (CA), practising agriculture in such a way so as to cause minimum damage to the environment, is being advocated at a large scale world-wide. Conservation tillage, the most important aspect of CA, is thought to take care of the soil health, plant growth and the environment. This paper aims to review the work done on conservation tillage in different agro-ecological regions so as to understand its impact from the perspectives of the soil, the crop and the environment. Research reports have identified several benefits of conservation tillage over conventional tillage (CT) with respect to soil physical, chemical and biological properties as well as crop yields. Not less than 25% of the greenhouse gas effluxes to the atmosphere are attributed to agriculture. Processes of climate change mitigation and adaptation found zero tillage (ZT) to be the most environmental friendly among different tillage techniques. Therefore, conservation tillage involving ZT and minimum tillage which has potential to break the surface compact zone in soil with reduced soil disturbance offers to lead to a better soil environment and crop yield with minimal impact on the environment.

“…Conservation agriculture (CA) practices are proposed to minimize soil degradation and improve soil quality. CA is defined as a tillage system where at least 30% of crop residues are left on the field surface, and it is a conservation practice to reduce soil erosion, improve water use efficiency, and regulate upper soil temperature [6,7]. CA integrates three principles, namely minimal soil disturbance, crop residue retention, and crop diversification through rotation or intercropping [6,8,9].…”

Conservation agriculture (CA) practices are advocated to reduce soil degradation, resulting in more sustainable food production as compared to conventional tillage (CT). In this study, the short-term effects of two tillage systems in combination with cropping patterns on selected soil physical parameters on four experimental sites in Mozambique were studied. The study sites differ according to their climatic conditions, soil types, and crop adaptation. Tillage systems evaluated were CA and CT, while the cropping pattern had four levels of sole cropping and three levels of intercropping. In general, soil physical properties showed significant changes due to the tillage systems, but the cropping pattern and their interaction with tillage systems did not yield significant impacts on the soil physical properties. CA increased bulk density, penetration resistance, and saturated hydraulic conductivity as compared to CT. A significant difference due to the tillage system was observed across the four sites, and in general, evaporation was higher in CT compared to CA. The presence of crop residues in CA contributed to lower evaporation. Thus, in the short term, CA practices could be a sustainable option to conserve soil water through higher infiltration and less evaporation.

“…The weather data for the years is presented in Table 1. Abeokuta is a transition between rainforest and derived savannah agro-ecology with a humid tropical climate and a mean annual rainfall of 1200mm.The soil of the experimental area was described as loamy sand and was classified as Arenic Plinthic Kandindalf [12]. Seven improved cowpea genotypes obtained from the Grain Legume Improvement Program (GLIP) of International Institute of Tropical Agriculture (IITA), Ibadan were used in the study.…”

Genotype × environment interaction (GEI) plays a significant role in determining the desirability or superiority of a genotype, hence the need to evaluate genotypes over wide range of environment. Seven improved cowpea genotypes were evaluated in four environments (years); the late seasons of 2009, 2010. 2011 and 2012 to determine their desirability based on mean grain yield and stability in Abeokuta Southwestern Nigeria using the Genotype+Genotype×environment (GGE) biplot. IT98K-573-2-1 had the highest mean grain yield while IFE-98-12 had the lowest. There was highly significant Genotype × Environment Interaction on seed yield (p<0.001) indicating the need for GEI analysis. The GGE biplot identified three mega-environments viz AB10 and AB11 as mega-environment 1, AB09 as the megaenvironment 2 and AB12 as the third. IT98K-573-2-1, IT04K-333-2 and IT04K-227-4 were the most responsive genotypes in mega-environments 1, 2 and 3 respectively. IT04K-227-4, IT04K-333-2, IT98K-573-1-1and IT98K-573-2-1 were identified to have performed above average while IT99K-1060, LDP10-OBR1 and IFE-98-12 yielded below average. LDP10-OBR1 was the most stable genotype but was low yielding. IT98K-573-2-1 was selected as the best combiner of high yield and stability and the most desirable for Abeokuta Southwestern Nigeria. AB10 was identified as the best among the test environments.
