EFFECT OF INTERCROPPING ON SUGARCANE AND ON BEAN CULTIVARS WITH DIFFERENT GROWTH HABITS BEHAVIOR
Keywords:
Saccharum officinarum, Phaseolus vulgaris, intercropping.Abstract
To provide a better use of the soil in the regions where sugarcane is grown, in the state of Rio Grande do Sul, an intercropping study was conducted to identify the best bean type to achieve higher yields. The bean cultivars tested were: determ i nate growth habit, type 1; 'Pampa `, indeterminate. type II; 'Macanudo. indeterm i- nate, type III. The sugarcane cultivar was CB4176. Two simultaneous sowings of the bean and sugarcane cultivara were performed, single and intercropped. The first experiment, from the sugarcane growth season of 1993, was sown in 09/27/91, and the second, of 1994, in 09/22/92. The results showed no interaction among year of sowing and the performance of the cultivars. Best beans plant type behavior were III, of cultivar 'Macanudo', and 11 of 'Pampa' . Sugarcane yield and piam population were affected by intercropping. The treatments sugarcane x `Macanudo' provided the best results concerning culm hight and diameter.
