“…These impacts must, therefore, be understood and optimized. In Mozambique, research on the individual effects of tillage systems and cropping patterns on soil physical properties has been conducted [19][20][21], but the information is scanty on the combined effects of tillage systems and cropping pattern on soil physical properties. Therefore, this study is conducted at four sites over two growing seasons to evaluate the impact of tillage systems and cropping patterns and their interactions on selected soil physical properties.…”

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.

“…Soybean is the main crop hampered by competition in intercropped systems with maize (Tsujimoto et al, 2015). Zhang et al (2015) found in their studies that the row arrangement used in the maize-soybean intercropping system interferes with the development of these crops.…”

“…In addition, studies show that soybean has the ability to improve the quality of maize silage, increasing its crude protein contents (Batista et al, 2019;Tsujimoto et al, 2015;Sánchez et al, 2010;Lempp et al, 2000), further justifying the need for studies evaluating the maize-soybean intercropping. Based on this context, the objective of the study was to evaluate the components of dry mass yield for silage and to measure the yield components and grain yield of maize crop in maize-soybean intercropping.…”

Maize is one of the main cereals produced worldwide and, in association withsoybean crop, can result in benefits to the production system. The objective of this study was to evaluate the biomass yield for silage and grain yield in maize crop, in the maizesoybean intercropping system. The study was conducted in the municipality of Dois Vizinhos - PR, Brazil, using a randomized block design, with nine treatments and four replicates. The treatments were composed of three maize hybrids grown in monoculture and in intercropping with two soybean cultivars (P1630+TMG7062, P1630+P95R51, P1630, LG6030+TMG7062, LG6030+P95R51, LG6030, P30F53+TMG7062, P30F53+P95R51 and P30F53). The data were subjected to analysis of variance and, when there was significance, Scott-Knott test was applied. Maize biomass yield for silage was approximately 4,000 kg ha-1 higher when the hybrids LG6030 and/or P30F53 were used. The cultivar TMG7062 stands out from P95R51 in terms of dry biomass yield for silage. The higher the percentage of soybean biomass added to the silage, the higher its crude protein content. However, crude protein yield per area was similar for the evaluated treatments. Some yield components (number of grains per row and thousand-grain weight) and grain yield of maize differ according to the hybrid used, but similarity is observed between intercropping and monoculture. There is evidence that the soybean cultivar TMG7062, intercropped with P1630, has the potential to reduce the grain yield of the cereal.

“…In this situation, Tsujimoto et al (2015) quantified the effect of the nitrogen on soil fertility for crop production in the Nacala corridor. Based on the results, the agriculture research centers in Mozambique (Instituto de Investigação Agrária de Moçambique (IIAM)) recommended the use of nitrogen fertilizers to farmers in this area.…”

The available phosphorus (P) in soil is a major limiting factor for maize productivity in the Nacala corridor, Mozambique. In this study, soils were collected from three representative sites, Ribaue, Nampula, and Nacala, in the area, and each was used for maize pot experiment with five P fertilizer levels. The soil-available P content was determined by the Mehlich-3 method at 30 days after P fertilization. The shoot biomass and P concentration at the tasseling stage increased as the P fertilizer level increased and were significantly expressed as a function of soil-available P. Based on the function, the available P that attains 90% of the maximum shoot biomass was estimated as 79 mg P 2 O 5 kg −1. Consequently, the results in this study suggest a recommendation of 32-74 kg P 2 O 5 ha −1 fertilizer for maize production in the Nacala corridor although a field evaluation and economical evaluation are necessary.
