Effect of cultivar and phosphorous fertilization on growth and yield of okra (Abelmoschus esculentus L.)

Abstract

An experiment was conducted during the growing season of 2008 in experimental field of Agric. College, AL-Hussienyia area to test the effect of two okra cultivars (Batra and Clemson-spineless) and five levels of phosphorous fertilization (0 , 20 , 30 , 40 and 50 kg P2O5 Donum) on growth and yield of okra. The layout of experiment was R.C.B.D. in Split Plot with three replicates and the comparison was done using L.S.D at 5% level of significance. results showed that (Batra cv.) and highest levels of phosphate fertilizer (40 and 50 kg P2O5 Donum) had significantly affected plant height, branches, leaf no., leaf area, pods no., early yield and total yield. Interaction effects showed a significant effect on branches, leaf area and total yield. Maximum total yield (4.0 Ton/Donum) was obtained from interaction between (Batra cv.) and (40 kg P2O5 Donum).
