“…between rows produced smaller amount of dry mass at corn harvest when compared to the simultaneous establishing methods of intercropping, and it can be used for soil cover or grazing in a period after corn harvest. According to Zhang & Li (2003), grasses have additional growth after the main crop harvest.…”

-The objective of this work was to evaluate methods of intercropping corn and Panicum spp. forages and their effects on corn yield and forage development. Two experiments with Panicum spp. were conducted, one with 'Tanzania' and other with 'Massai' in the municipality of Piracicaba, in the state of São Paulo, Brazil, in the 2012/2013 growing season. In both experiments, the treatments were: broadcast seeding of Panicum spp. at the same time of corn sowing; corn with Panicum spp. between rows; Panicum spp. sown with fertilizer; Panicum spp. sown between corn rows after corn establishment; broadcast seeding of Panicum spp. after corn establishment; and sole corn sowing. For corn, leaf nitrogen content, ear height, and grain yield were evaluated. For Panicum spp. cultivars, height, dry mass, tiller density, and leaf:stem ratio were evaluated. The intercropping establishment methods used do not affect corn growth, grain yield, and N leaf content. The seeding of both cultivars of Panicum spp. when corn plants had four expanded leaves reduces forage dry mass production and increases the leaf:stem ratio. The Panicum spp. broadcast method, performed after corn was established, does not allow appropriate establishment, with few plants in the area.Index terms: Zea mays, guinea grass, interspecific competition, tropical perennial grass. Produtividade de milho, produção e qualidade de forragem afetadas pelos métodos de consórcio do milho com Panicum maximumResumo -O objetivo deste trabalho foi avaliar métodos de implantação do consórcio milho e espécies forrageiras de Panicum spp. e os efeitos na produtividade do milho e no desenvolvimento das forragens. Dois experimentos com Panicum spp. foram conduzidos, um com 'Tanzania' e outro com 'Massai' em Piracicaba, SP, na safra 2012/2013. Em ambos os experimentos, os tratamentos foram: Panicum spp. semeado a lanço no momento da semeadura do milho; milho com Panicum spp. nas entrelinhas; Panicum spp. semeado com fertilizante; Panicum spp. semeado nas entrelinhas depois do estabelecimento do milho; Panicum spp. semeado a lanço depois do estabelecimento do milho; e milho solteiro. Para o milho, avaliaram-se a concentração de nitrogênio foliar, a altura de espigas e a produtividade de grãos. Para as cultivares de Panicum spp., avaliaram-se altura, massa seca, número de perfilhos e relação folha:colmo. Os métodos de implantação do consórcio avaliados não afetam o crescimento, a produtividade de grãos e a concentração foliar de N do milho. A implantação das cultivares de Panicum spp., quando o milho apresenta quatro folhas expandidas, reduz a massa seca e aumenta a relação folha:colmo das plantas forrageiras. A semeadura a lanço de Panicum spp., depois do estabelecimento do milho, não permite o estabelecimento adequado, com poucas plantas na área.

“…One of the logical approaches to increasing forage production to overcome these problems is pasture improvement by grass and legume mix cropping system (Ajayi et al, 2007). Mix cropping is one of the multiple cropping system, has been practiced by farmer for many years in various ways and most areas (Zhang & Li, 2003). The advantage of grass/ legume mix cropping in pasture is the possibility of N addition from the legume to the grass.…”

This research was conducted to evaluate production, different competition indices and nutritive value of Setaria splendida, Centrosema pubescens, and Clitoria ternatea in monoculture and mix cropping system on peat soil land. The experiment was set up in a randomized complete block design with five treatments and three replications. The five treatments were: S. splendida sole cropping (SS), C. pubescens sole cropping (CP), C. ternatea sole cropping (CT), S. splendida and C. pubescens mix cropping (SS/CP) and S. splendida/C. ternatea mix cropping (SS/CT). The DM yield of S. splendida in mixed cropping with C. pubescens increased 43.4% and in mix cropping with C. ternatea increased 15.7% compared to sole S. splendida. The value of land equivalent ratio of SS/CP (LER SS/CP ) was >1. The LER SS/CT value was <1. The crowding coefficient value of S. splendida (K SS ) was higher than K CP and K CT . The total value of K SS/CP and K SS/CT were >1. The competition ratio (CR) values of S. splendida in both mix cropping were >1. The agressivity (A) values of S. splendida in both mix cropping were positive. The crude protein, NDF and ADF content of forage were not affected by mix cropping system. In conclusion, mix cropping in peatland do not affect productivity and nutritive value of S. splendida, C. pubescens, and C. ternatea. S. splendida is more effective in exploiting environmental resources when intercropped with C. pubescens compared to C. ternatea on peatland.Key words: croppin�� system, �ora��e, production, �uality croppin�� system, �ora��e, production, �uality Nilai agressivity (A) S. splendida pada kedua pertanaman campuran adalah positif. Kandungan PK, NDF, dan ADF hijauan tidak terpengaruh oleh sistem pertanaman campuran. Dapat disimpulkan bahwa pertanaman campuran di lahan gambut tidak mempengaruhi produktivitas dan nilai nutrisi S. splendida, C. pubescens, dan C. ternatea. S. splendida lebih kompetitif dan dominan dibanding C. pubescens dan C. ternatea di lahan gambut. ABSTRAK

“…The main idea of intercropping is to get improved productivity per unit land area and time, and also impartial and judicious exploitation of land resources and farming inputs including labour. Most studies on intercropping focused on productive and sustainable system, ie on the legume-cereal intercropping (Fusuo & Li, 2003). Legumes in maize based cropping systems are considered to be better alternatives for securing nitrogen economy and increasing yield of maize besides bonus yield, greater productivity per unit time and space and higher net returns of intercropping system over monoculture (Thayamini & Brintha, 2010).…”

Low forage quality and low corn yield experienced due to continuous monoculture resulting from persistent soil depletion in the developing world have generated the need for a sustainable practice to improve quality and yield of aforementioned. This review examines the salient issues that relates to the effect of intercropping some selected legume in different cropping patterns with corn in order to improve the yield and forage quality of corn, and that of quality feed/forage production. Two legumes species namely: Bambara groundnut and Peanut were the key crops focused with the main corn crop in this review work.
