“…In addition, crotalaria presents a high allelopathic activity that reduces weed competition with the crop of commercial interest. It also incorporates around 150 to 450 kg ha -1 of N per year into the productive system, which can favor the productivity of corn in succession (M. A. C. de Carvalho et al, 2004;Martinez et al, 2019;Paz et al, 2019). Corroborating with the results, the works conducted by Brito et al (2017), Chieza et al (2017), and Queiroz et al ( 2010) also showed higher yields of corn grown in winter under crotalaria straw.…”

“…While there are other studies where intercropping positively influenced productivity (Batista et al, 2011;Martinez et al, 2019;Paz et al, 2017;Seidel et al, 2014), the same precepts hold for research where corn is grown in succession to green manure plants. According to Marcelo, et al, (2012) and Brito et al (2017), there are increases in corn productivity and residues in the soil in succession cultivation.…”

This paper aimed to evaluate the productivity of corn crop for silage, beans and straw production in different crop rotation systems with spring/summer and fall/winter green manures cultivated under agroecological production management. The experiment was implemented in a rural property managed in an agroecological system since 2009, in the 2017/18 and 2018 crops. The experimental design used was in randomized blocks, with five repetitions. The treatments consisted of four different crop rotation systems: monocrop corn/monocrop corn/fallow/beans; corn + cowpea/monocrop corn/oats/beans; corn + crotalaria/monocrop corn/forage radish/beans and corn + jack bean/monocrop corn/vetch/beans. After the 2018 second crop of corn was removed, the winter/spring green manures were sown: forage radish, vetch, and oats. This was followed in September by the bean crop. The dry matter yields of corn for silage in each growing season and of the bean were evaluated, as well as the total productivity of the systems. The straw yield was also evaluated. The crop rotation systems that included green manures presented the highest total productivity. The intercropping with pork bean favored the corn productivity in the harvest and the crotalaria stover favored the productivity in the off-season. The corn + cowpea/jack bean/beans monocrop and corn + crotalaria/jack bean/forage radish/beans systems favored the productivity of beans. The mode corn monocrop/corn monocrop/fallow did not prioritize the accumulation of straw on the soil.

“…According to Paz et al . (2017), the higher forage mass obtained in some corn intercropping with legumes is due to sowing area optimization, in which the secondary crop interferes less in corn growth (lower competition for light, water and nutrients).…”

The objective of this study was to evaluate the effect of different intercropping and spacing arrangements of corn (Zea mays L) and crotalaria (Crotalaria spp) on the agronomic characteristics, chemical composition and forage digestibility. The experiment was distributed in a randomized complete block design with a 2 × 2 + 1 factorial scheme. The treatments were two cultivation systems (corn + Crotalaria juncea (CCJ) intercropping, and corn + Crotalaria ochroleuca (CCO) intercropping), in two spacing arrangements (A1 (corn and crotalaria sown in the same row) and A2 (corn and crotalaria sown in alternate rows)) plus control (single corn monocropping (CSC)), with six replicates per treatment, for 2 years. Forage plants were harvested when the corn grain reached the doughy-farinaceous phenological stage. Forage mass (total and of each species), morphological composition, chemical composition and in vitro digestibility were evaluated. The forage accumulation was higher for the A1 spatial arrangement. In the second year, the highest total forage mass was verified in the CCO intercropping (11 140 kg/ha). The highest corn mass (9402 kg/ha) was observed for CSC. The highest crotalaria mass was observed in the CCJ intercropping in both years. Regarding the chemical composition, CCJ and CCO intercropping had the highest crude protein concentration. The lowest acid detergent fibre concentration was observed in CSC and CCO intercropping, directly reflecting the in vitro dry matter digestibility coefficients. It is concluded that C. ochroleuca, sown between corn rows, had higher forage accumulation and nutritive value among the treatments tested in this experiment.

“…Corn plants need adequate conditions of solar radiation interception, which is a direct function of population density and plant distribution in the area (Storck et al, 2015). Corn intercropped with legumes generates an advantage because its physiology is more efficient in carbon sequestration and dry matter accumulation at high temperatures, with a beneficial effect in subsequent years in the same intercropping area (Paz et al, 2012).…”

Soil Attributes and Initial Corn Development as a Function of Fertilization and Intercropping Systems

et al. 2019

View full text Add to dashboard Cite

Fertilization systems that allow higher sowing speeds have been used in areas of grain production, as well as the use of intercropping to improve soil physical quality and provide better soil cover. This study aimed to evaluate soil attributes and the initial corn development and intercropping (corn + velvet bean, corn + pigeonpea, and corn + bonavist bean) as a function of fertilization systems (pre-sowing and sowing). The experiment was conducted in an Oxisol in a randomized block design in the 2 × 3 factorial scheme, with four replications. The number of days for emergence, plant stand, intercropping dry matter, soil straw cover, soil straw permanence index, penetration resistance, soil moisture, soil density, degree of compaction, and total soil porosity were measured. The percentage of soil straw cover was affected by fertilization system, mainly by pre-sowing fertilization. Soil physical attributes were not affected by fertilization and intercropping systems, except total porosity, in the 0-0.10 m layer, which has a combined effect of factors. The initial corn development was not affected by fertilization and intercropping systems. Velvet bean presented the highest number of days for the emergence and lower dry matter.
