Abstract
The effect of Alar concentrations at different times was evaluated using pots in a Factorial Experiment in Completely Ramdomized Design with three replications. The concentrations were: 0, 1,000, 5,000 and 10,000 ppm while the time of application were: 30, 40 and 50 days after emergence.
Flowering occurred 26 to 28 days after emergence. Harvesting started 121 days after emergence for all the treatments. Leaf size was not affected by the treatments. However, number of filled pods significantly increased while the unfilled pods significantly decreased with increasing concentration of Alar. Shelling percentage and weight of both seeds and shell increased with 5,000 ppm applied 50 days after emergence, hence, this treatment combination obtained the highest yield of 4.11 tons/ha.
