Intercropping Corn With a Combination of Tree Species to Control Weeds

Abstract

-The combination of crop residues or crop extracts is often more advantageous in controlling weeds, than the application of each residue or extract singly. This suggests that in intercropping with maize, the combination of tree species can be more advantageous than species isolated in weed control. The objective of this study was to evaluate the effects of intercropping with a combination of leguminous on the weed growth and corn yield. A randomized-block design with split plots (cultivars in plots) and five replicates was established. The cultivars BR 205 and AG 1041 were subject to the following treatments: two weedings (A), intercropping with sabiá (B), gliricidia (C), gliricidia + sabiá (D) and no weeding (E). In the B and C, 30 viable seeds m -2 of the leguminous were sown. In the D, 15 seeds of each species were sown m -2 . The legumes were sown by random casting during corn planting. The sequence of the best treatments in reducing the growth of weeds is A > B = C = D = E. The sequence of the best treatments when are considered the yields of baby corn, green corn and grain is A > B > C > D > E. The cultivars do not differ in regards to the reduction in weed growth. In terms of corn yield cultivar BR 205 is the best.Keywords: Zea mays, Gliricidia sepium, Mimosa caesalpiniifolia, green corn, grain yield. RESUMO -A combinação de resíduos ou extratos das culturas frequentemente é mais vantajosa do que a aplicação isolada dos resíduos ou extratos, no controle das plantas daninhas. Isso sugere que, na consorciação com o milho, a combinação de espécies arbóreas pode ser mais vantajosa do que espécies isoladas no controle de plantas daninhas. O objetivo deste estudo foi avaliar os efeitos da consorciação do milho com uma combinação de leguminosas arbóreas sobre o crescimento das plantas daninhas e o rendimento do milho. Utilizou-se o delineamento de blocos casualizados com parcelas subdivididas (cultivares nas parcelas) e cinco repetições. Os cultivares BR 205 e AG 1041 foram submetidos aos seguintes tratamentos: duas capinas (A), consorciação com a sabiá (B), consorciação com a gliricídia (C), consorciação com a sabiá + gliricídia (D) e sem capinas (E).

Intercropping forage cactus genotypes with wood species in a semi‐arid environment

“…The average values of height (84.83 cm) and width (87.64 cm) of cacti obtained from this research are similar to the values reported by da Silva et al (2015) for the genotypes Miúda (68.11 cm height and 88.44 cm width) and Orelha de Elefante Mexicana (80.56 cm height and 101.78 cm width) evaluated at 2 yr after planting in dry conditions in the municipality of Serra Talhada, Pernambuco, Brazilian semi-arid region.…”

“…Forage cactus is widely cultivated in the Brazilian semi‐arid region and is mainly used for animal feed in times of rainfall scarcity (Aguiar et al., 2019). Intercropping (companion cropping) of two or more plant species is a sustainable agricultural approach that can result in numerous environmental and economic benefits such as improved functioning of soil microbial communities, recovery of soil fertility, and consequent increase in production (Curtright & Tiemann, 2021; Raza et al., 2021; P. Silva et al., 2015). In fact, intercropping can reduce water demand and improve water use efficiency, thus reducing water consumption in agriculture (Raza et al., 2021).…”

“…Intercropping has been pointed out as the most viable and sustainable approach to improve the efficiency of water use in agricultural production (Raza et al., 2021; Ren et al., 2019). In general, intercropping can decrease runoff; increase soil water content; improve the functioning of soil microbial communities; increase resource efficiency, such as sunlight, water, and nutrients; and reduce pests and diseases, thus increasing crop yields (Du et al., 2018; Gitari et al., 2018; Liu et al., 2018; Rahman et al., 2017; Raza et al., 2021; P. Silva et al., 2015). Intercropping forage cactus with Sorghum spp.…”

Competitividade de <i>Gliricidia sepium</i> convivendo com diferentes plantas daninhas

“…Tabela 1 -Altura (cm) de mudas de Gliricidia sepium, submetidas à competição com plantas daninhas ao longo de 60 dias após transplantio (DAT) Estudos apontam a capacidade supressora da cobertura morta de ramos de gliricídia sobre as plantas daninhas ou sua contribuição no controle das infestantes quando em consorciação com o milho (Oke, 2012;Fernades;Chicas, 2015;Oliveira, 2020). Contudo, no presente estudo verificouse a suscetibilidade das mudas da espécie arbórea à interferência causada pelas plantas daninhas.…”

Does Intercropping of Baby Corn (<em>Zea mays</em> L.) with Pulse Legumes Improve Soil Fertility, Crop Productivity and Profitability?

“…In this study, although intercropping of baby corn with pulse legumes did not significantly reduce baby corn growth and productivity, they did reduce growth and productivity of the corn in all treatment combinations and the most reductions were found in baby corn with crawling cowpea and mungbean, respectively. The reductions in growth and productivity of baby corn were not surprising as pulse legumes acted as weeds that competed with baby corn for water, nutrients and solar radiation (Silva et al, 2015). As nitrogen fixing crops and pulse legumes, the authors expected to find the benefit of the legumes from nitrogen fixation and the additional income that was high enough to reimburse the crop loss from competition.…”
