“…This was associated with a significant increase in the number of pods per unit area. Morgade and Willey (2003) attributed the increase in yield to increased densities per unit area. This confirms the observation by Shirtliffe and Johnston (2002) that high population density contributes to higher seed yield.…”

“…One of the constraints is lack of information necessary for the production of high seed yield and good quality that offers good planting materials to farmers. Variation of plant population affects total bean yields (Morgade and Willey, 2003). Maximizing the yield of green beans requires a review of the current used plant population density in order to determine a population that could produce the highest seed yield of good quality, maximize the use of the land and help solve problems on weed management, disease and pest incidence and low yield.…”

Seed is the basic unit for any agricultural production system. Without quality seed, no one can even think of good harvest and green been (Phaseolus vulgaris L.) production. Seed producers have to meet farmers seed demand by adopting appropriate plant population and arrangement pattern which would give them satisfactory seed yield of good quality. Previous researches on the same subject indicate that square arrangement results in high yield while others found no clear differences yet others advocate the use of higher plant densities during production. Several plant population densities (125,000 plants/ha, 163,265 plants/ha, 222,222 plants/ha and 320,000plants/ha) and three planting arrangement patterns (square, R50 and R40) were investigated in this study. Comparison of bush bean seed yield was highest (0.50t/ha) at population of 222,222 plants/ha and when planted in square arrangement pattern and least (0.13t/ha) at population of 360,000 plants/ha. Seed size was only influenced by plant population and not affected by plant arrangement pattern. Plant population density strongly influenced the percent of good seeds developed with populations of 125,000 and 163,265 plants/ha producing 97.01% and 96.15%, respectively. Germination of the harvested seeds was insignificant at all plant densities. The highest speed of germination (77.62%) of seeds was observed from a population density of 320,000 plants/ha. Therefore, green bean seed producers can adjust their planting density to 222,222 plants/ha in square arrangement to maximize seed yield

“…Total dry matter accumulation per plant of maize in intercropping was not different from sole cropping in early stages of growth (Ofori & Stern, 1986). Variation on patterns of dry matter accumulation of intercropped maize due to bean population was marginal, with no consistent tendency after 33 DAS.…”

“…Grain yield per unit area of intercropped beans decreased as maize population increased from M1 to M2 (Mutungamiri et al, 2001) in all bean populations at N2 and in B2 at N1 (Table 5). Decreases were caused by reduction on number of pods per plant.…”

Establishment of the ideal number of plant is a crucial point for obtaining maximum profits while cropping different species together. The main objective of the study was to investigate the effect of different plant populations of maize and beans, at two nitrogen levels, on the performance of the component crops. Two maize (20,000 and 40,000 plants ha -1 ) and three bean (30,000; 60,000 and 90,000 plants ha -1 ) populations were tested in a randomized complete block design with tree replicates. Grain yields of maize and beans were affected by intercropping and the effect was more detrimental to the legume mainly at the highest maize plant population. The application of nitrogen fertilizer to maize rows mitigated intercropping effect on maize at higher population (40,000 plants ha -1 ) and, at lower maize plant population (20,000 plants ha -1 ), benefited the associated beans by increasing grain yields. Land Equivalent Ratio values for grain yields of maize and beans showed that intercropping compared to sole cropping is advantageous and best indices were obtained at a bean plant population of 60,000 plants ha -1 . Key words: Zea mays, Phaseolus vulgaris, cropping system, plant density POPULAÇÃO ÓTIMA DE PLANTAS NO CONSÓRCIO MILHO-FEIJÃO NO SEMI-ÁRIDO BRASILEIRORESUMO: A definição do número de plantas por área é fundamental para a obtenção de ganhos quando diferentes espécies são plantadas juntas. O principal objetivo do estudo foi investigar o efeito de diferentes populações de plantas, sob dois níveis de nitrogênio, no desempenho do milho e do feijão em plantio consorciado Duas populações de milho (20.000 e 40.000 plantas ha -1 ) e três de feijão (30.000; 60.000 e 90.000 plantas ha -1 ) foram testadas em um delineamento de blocos ao acaso com três repetições. As produções de grãos de milho e feijão foram afetadas pelo consórcio, sendo o efeito mais prejudicial para a leguminosa. A aplicação de fertilizante nitrogenado diminuiu o efeito competitivo do consórcio para o milho na maior população (40.000 plantas ha -1 ), e, na menor população (20.000 plantas ha -1 ), favoreceu o feijão com o aumento de sua produção de grãos. Os índices para Uso Eficiente da Terra para produção de grãos de milho e feijão revelaram que o consórcio é mais vantajoso que o plantio isolado das culturas, com os melhores valores com a população de plantas de feijão correspondente a 60.000 plantas ha -1 .

Choosing the species suitable for cultivation in intercropped systems is a critical limiting factor for grain and forage production. This study aimed to evaluate the growth, nodulation, production, and physiology of cowpea (Vigna unguiculata) and guandu bean (Cajanus cajan) intercropped with buffel grass (Cenchrus ciliaris) and Eucalyptus urograndis (Eucalyptus grandis × Eucalyptus urophylla) in an integrated production system. Two experiments were conducted simultaneously, arranged in a 2 × 4 factorial scheme. The first factor consisted of the use of two integrated production systems. The second factor consisted of four distances (2, 4, 6, and 8 m) from the eucalyptus planting rows. In the first experiment, crop-forest systems (CFIS: eucalyptus trees and cowpea) and crop-livestock-forest systems (CLFIS: eucalyptus trees, cowpea, and buffel grass) were evaluated. In the second, livestock-forest systems LFIS1 (eucalyptus trees and guandu bean) and LFIS2 (eucalyptus trees, guandu bean, and buffel grass) were evaluated. In cowpea, nodulation was not influenced by production systems and distances, whereas in guandu bean, there was a reduction in the nodules' number and dry mass with the distance from the trees. Higher growth, biomass production, and photosynthetic activity of cowpea and guandu bean were observed with the increasing distance from the eucalyptus planting rows. However, cowpea increased the 100-seed weight at 2 and 4 m distances from the eucalyptus rows, improving the grains' quality close to the trees. The simultaneous cultivation with buffel grass did not affect the leguminous plant yield, promoting greater diversification and increasing the total biomass production of the intercropping.
