The planting pattern effects on yield and yield components of tropical beans genotypes at Jiroft in Iran

To evaluate The planting pattern effects on phonological characteristics yield and yield components of tropical beans genotypes experiment was conducted in Jiroft Islamic Azad University research farm during 2009. The experiment used in split plot design based on RCBD with four replications. Plant arrangements were considered in three levels as one row on the stack with a distance between a plant 10 cm، two rows on the stack with a distance between plants 20cm and three rows on the stack with a distance between plants 30cm، as the main plot and genotypes at three levels (cowpea، cream tepary bean and black tepary bean) as sub plot were studied. Characteristics such as grain yield، straw yield، the number of pods per plant، seeds per pod، and average pod length، plant height، seed weight، and harvest index، number of seeds per plant، biological yield، and changes in dry weight were studied. The trait of black tepary bean with planting arrangement of three rows on the stack with a distance between plants 30cm with the maximum number of pods per plant (20. 90) and maximum number of seeds per plant (266. 5) and maximum harvest index (46. 55%) to black tepary bean with planting arrangement of two rows on the stack with a distance between plants 20cm. Genotypes that studied of the number of pods per plant، seeds per pod، average pod length، seed weight and، number of seeds per plant in the 1% probability level were significant.
