The effects of irrigation and sowing date on the quantitative traits of okra (Abelmoschus esculentus L.)
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 5
Abstract
The correct management of agricultural operations in okra cultivation is one of the success factors in achieving high performance. Selecting an appropriate sowing date and irrigation interval are two important factors in optimal development of crops. To evaluate the effects of irrigation intervals and planting dates on fresh pod yield and yield components of okra, an experiment was conducted using strip plot design in randomized complete block with three replications in Sirjan during 2012. Irrigation treatment at three levels (5 days, 7 days and 10 day intervals) was placed in vertical plots and planting dates were applied at five levels (30th April, 7th May, 14th May, 21th May, 28th May) in the horizontal plots. In this experiment, traits of stem length, stem diameter, number of branches per plant, number of leaves per plant, pod length, number of pods per plant and fresh pod yield were measured. Results showed that the effect of irrigation on all traits was significant. Increasing the irrigation intervals from 5 days to 10 days decreased the mentioned characters averages, significantly. The effect of planting date on the means of all traits were significant; so that delayed planting date from 30th April to 14th May, increased all means of above mentioned traits significantly and then to 28th May showed a decreasing trend. The highest fresh pod yields were obtained on 14th May (10235 kg ha-1) and 5 days irrigation interval (9993.5kg ha-1).
