Evaluation of Maize and Green Bean Yield In Various Densities and Different Sowing Rates of Intercropping by Replacement Method

28832

Intercropping of cereals with legumes has been popular in humid tropical environments. In order to evaluation of yield on maize and green bean in various densities and arrangements of intercropping by replacement method, an experiment was conducted as split plot design in completely randomized blocks with three replications in Macoo, Iran in 2009 crop year. The main factor included three density levels (D1: 60000 plants of maize + 200000 plants of green bean per hectare, D2: 75000 plants of maize + 300000 plants of green bean per hectare and D3: 90000 plants of maize + 400000 plants of green bean per hectare, respectively). The sub factor included five planting arrangements (R1: pure cultivation of green bean, R2: pure cultivation of maize, R3: intercropping 50% green bean + 50% maize, R4: intercropping 75% green bean + 25% maize and R5: intercropping of 25% green bean + 75% maize, respectively). The results of variance analysis showed maize grain yield was significantly affected by different arrangements of intercropping cultivation and in the green bean was affected by different levels of density. For evaluation of intercropping, Land Equivalent Ratio (LER) and Relative Value Total (RVT) were calculated. The highest amount of LER and RVT were in treatments D3R4 and D3R5 about 2.17 and treatment D3R4 and D3R5 about 3.16, respectively. As a conclusion, the mentioned combinations are economically advisable. In relation to competitive indices, the Relative Crowding Coefficient (RCC) and Dominancy were calculated. The highest RCC related to the maize with 1.18 was observed in D2R3 treatment. Also, the green bean in D2R4 treatment with 1.05 was indicated the highest RCC. The highest dominancy with 2.95 in D3R5 treatment was calculated whereas the lowest was D3R3 treatment with -3.04. The Relative Crowding Coefficient were associated the maize in most treatments
