Growth Response of Dekoko (Pisum sativum var. abyssinicum) to Nitrogen and Phosphorus Fertilizers at Enderta Woreda, Northern Ethiopia
Abstract
A field experiment was conducted to investigate the influence of different nitrogen and phosphorus fertilizer on dekoko (Pisum sativum var.abyssinicum) growth parameters. The Experiment was conducted in 2013/14 at the experimental field of Mekelle University Endayesus Campus, Northern Ethiopia. The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications. It comprises four treatments viz. Control (with no fertilizer), 30 kg N ha-1+30 kg P2O5 ha-1, 60 kg N ha-1+60 kg P2O5 ha-1 and 90 kg N ha-1+90 kg P2O5 ha-1. Data on growth parameters like: leaf area, number of branches per plant and plant height were measured and collected. Results show that, the effect of N + P2O5 on in all the growth parameters of dekoko was significant at 5% Probability level. The highest leaf area index (2.82m2m-2) among N+P2O5 levels, was recorded from 90 Kg/ha N +90 Kg/ha P2O5. Similarly highest Plant height (50.83Cm) was found from the treatment combination of 90 Kg/ha N +90 Kg/ha P2O5. Maximum number of basal branches (2.73) was obtained from the highest treatment combination.
