EFFECT OF PHOSPHORUS FERTILIZER RATES ON THE GROWTH, FRUIT YIELD AND NUTRITIONAL QUALITY OF OKRA VARIETIES
Abstract
Experiment was carried out at Teaching and Research Farm, Ladoke Akintola University of
Technology, Ogbomosho, to determine the effect of phosphorus fertilizer on the growth, fruit yield
and nutritional quality of okra varieties. Single super phosphate was used as a source of
phosphorus. Three varieties of okra were used (NHAe 47-4, Aresewosun, Iwo-agboin-in) and five
treatments of phosphorus (0,15,30,45 and 60Kg25/ha).
The 3×5 factorial experiment was laid out in a randomized complete block design (RCBD) with
three replicate. The growth parameters (plant height and number of leaves) and nutritional quality
were assessed. The data collected were subjected to analysis of variance (ANOVA) and significant
means separated using Least significant difference (LSD) at 5% probability level.
Result obtained showed that the growth parameter increased as the plant aged. Okra planted with
the fertilizer rate of 60Kg25/ha) significantly improved the growth parameters.
Arora et al., (1991) compared the growth and yield of a new okra cultivar, Punjab Padmini, with
that of cv. Pusa Sawni grown under variable N (0, 30, 60 and 90 kg/ha) fertilizer application. They
stated that plant height, number of pods, pod size and total green pod yield were significantly
improved by the application of 90 kg N/ha and 60 kg P/ha which is in collide with this study.
