Assessment of yield, yield components and harvest index of bean cultivars under different plant densities in Ardal province
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 9
Abstract
In order to evaluate the agronomic and physiological characteristics of bean cultivars under different plant densities, a factorial experiment was conducted in the lay out randomized complete block design with three replications in Chahar mahal va Bakhtiari state. Three bean cultivars were selected for these purpose entitled land race (red), Shokufa (white) and Talash (Chiti). Plant densities were three; 50*100 cm (200.000 plant/ha), 50*20 cm (100000 plant/ha) and 50*30 cm (66000 plant/ha). Analysis of variance for all the studied traits showed significant differences among main and interaction effect of plant densities and bean cultivars for majority of the traits. For example, in the last growth phases, the maximum number of seed/pod and 100-seed weight were produced in 6.6 plant/m2 and Shokufa cultivar. The highest number of pod/plant were shown in 10 plant/m2 and Talash cultivar while maximum percentage of harvest index were calculated in 20 plant/m2 and Talash cultivar. Plant densities 20, 10 and 6.6 plant/m2 having 2441.11, 1637.70 and 1486.67 Kg/ha while Land race, Talash and Shokufa cultivars having 2073.33, 1806.67 and 1685.56 Kg/ha showed highest to lowest yield in this experiment.
