Productive Performance of Carrot and Cowpea Intercropping System Under Different Spatial Arrangements and Population Densities

Abstract

Spatial arrangement and population density of component cultures, when well structured, may contribute to increased crop yields relative to monocultures. Thus, the objective of this work was to evaluate the productive performance of carrot and cowpea in an intercropping system under different spatial arrangements and population densities. This research was conducted on the “Rafael Fernandes” experimental farm of the Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró, RN, Brazil. The experimental design was a randomized complete block with four replicates, where the treatments were arranged in a 3 × 4 factorial scheme, in which the first factor was three spatial arrangements (2:2, 3:3, and 4:4) and the second factor was four different population densities of cowpea (100%, 80%, 60%, and 40% of the recommended population in the single crop [RPSC]). Rooster tree Calotropis procera (Ait.) R.Br., a spontaneous species of the „Caatinga‟ biome, was used as fertilizer. The characteristics evaluated in carrot were as follows: total and commercial productivity of roots and classified root production. The following characteristics were evaluated for cowpea: number of pods per square meter, length and yield of green pods, number of grains per pod, 100grain weight, and yield of green grains. The modified monetary advantage was used to evaluate the feasibility of the intercropped systems. Spatial arrangements between the component cultures did not influence the agroeconomic performance of the carrot-cowpea intercropping system. The highest agro-economic performance of the carrot-cowpea intercropping was obtained in the population of cowpea, which was 42% of the RPSC.

“…Silva et al (2018) relataram o experimento bem-sucedido, confirmando ser um adubo agronomicamente viável em cultivo consorciado de cenoura e alface. Ribeiro et al (2018) descreveram uma alta performance agroeconômica do cultivo consorciado entre cenoura e feijão-caupi adubado organicamente com C. procera. Batista et al (2016), puderam observar que adubação verde com base na utilização de 3 espécimes (jitirana, mata pasto e flor-de-seda, a C. procera) ocasionaram um melhor aproveitamento das características químicas no solo e das plantas de beterraba.…”

“…Frutas e derivados de seriguela são amplamente comercializados em feiras populares, supermercados e restaurantes da região nordeste do Brasil. Esta fruta tem uma cor e sabor agradáveis, e a características de qualidade desta fruta são consideradas importantes para a sua comercialização (RIBEIRO et al, 2018). Apesar de a fruta conter um caroço consideravelmente grande, apresenta um rendimento em polpa >50%, o que comprova uma forte potencialidade no processamento industrial, podendo ser utilizada na elaboração de bebidas fermentadas, geleias, sucos, compotas, sorvetes, licores e refrigerantes (NERIS et al, 2017).…”

Biological and economic efficacy of cowpea-radish association fertilized with organic manure in diverse planting arrangements

“…In the field experiments, it followed the Bhatt (2011) recommendation for the statistical design, and for cowpea and radish crops management in intercropping and in monocropping, besides the materials used in conducting these experiments, they were used the methodologies established by Nunes et al (2018); Pereira et al (2018); Ribeiro et al (2018) and Moraes et al (2019).…”

Agro-economic responsiveness of radish associations with cowpea in the presence of different amounts of Calotropis procera, spatial arrangements and agricultural crops

“…It is worth noting that spatial arrangements can also affect the production characteristics and productivities of many crops (Bezerra et al, 2014). However, studies carried out in the northeastern semi-arid region of Brazil report that in the association between carrot and cowpea, tuberose presented the best use of environmental resources in the 2:2 arrangement for commercial roots (Ribeiro et al, 2018).…”
