Effect of compost and EXPERT TM fertilizer on the vegetative parameters of bush beans (Phaseolus vulgaris L.)

Abstract

A pot experiment was laid out in complete randomized design with seven treatments and three replications to evaluate the vegetative parameters of bush beans cv top crop. Treatments included applications of compost (1-2 kg/m² as basal) and expert M fertilizer (20-30 g/m² (topdressing) at different levels. After 40 days of seeding, fresh and dry weights of leaves, roots and shoots, number of nodules and leaf area were measured and recorded. All the collected data were subjected to statistical analysis. The results revealed that 2 kg/m² compost with 30 g/m² expert fertilizer treatment had higher values in leaf area and plant biomass than other treatments and showed significant differences in most of vegetative parameters. This treatment was statistically similar in its effect on leaf area and plant biomass with 1.5 kg/m² compost and 30 g/m² expert fertilizer treatment. Nodulation was high in 1.5 kg/m² compost than that in 2 kg/m² compost along with 30 g/m² expert fertilizer. Therefore, it would be concluded that 1.5 kg/m² compost with 30 g/m² expert fertilizer application would increase vegetative and reproductive growth of beans than NPK fertilizer alone.
