Popis: | Field experiments were conducted in 2007 and 2008 at Calabar in the south eastern rainforest zone of Nigeria to evaluate the response of okra ( Abelmoschus esculentus (L.) Moench ) to four rates of nitrogen (0, 40, 80 and 120kg/ha) and three rates of lime (0, 5 and 10t/ha). Factorial combinations of the treatments were laid out in a randomized complete block design with three replications. Nitrogen had significant effects on plant height, number of leaves and branches/plant, number of pods/plant, fresh pod weight and total fresh pod yield. The 80kgN/ha rate maximized all the growth and yield attributes. Lime application had no consistent effect on plant height and number of branches/plant; but significantly improved all other growth and yield attributes. Total fresh pod yield was highest at 5t/ha lime rate, and this was 91% higher than the control. Significant interactions were recorded between nitrogen and lime on number of leaves/plant and fresh pod yields, with the combination of nitrogen and lime at 80kg/ha and 5t/ha giving the highest values. |
