Determining of Phosphorus Fertilizer and Plant Population for Yield and Yield Attributes of Kik-Type Field Pea (Pisum sativum) in North West Ethiopia (Published)
Field pea experiment having different intra-row and inter-row spacing as well as phosphorous fertilizer was conducted at Debre Markos Agricultural Research station in order to refine economically optimum plant spacing and phosphorus fertilizer level. A factorial combination of five P2O5 rates (0, 23, 46, 69 and 92 kg ha-1), two intra-rows (5, 10 cm) and two inter-row (20, 30 cm) spacing was carried out using randomized complete block design with three replications. The results of the analysis of variance indicate that phosphorous fertilizer had a significant effect (p<0.05) on seed yield and yield attributes of field pea, the main effects of intra-row spacing and inter- row spacing had a significant effect (p<0.05) on number of pods per plant, seed and biological yield. The combination of 10 cm intra-row spacing and 30 cm inter-row spacing resulted in the highest seed yield for field pea. Additionally, the maximum seed yield (1942.39 kg ha-1) and net benefit ETB 66,369.26 was observed at 92 P2O5 kg ha-1. Hence, plating kik-type field pea with 10 cm intra-row and 30 cm inter-row spacing's with application of 92 P2O5 kg ha-1is found to be economically feasible and recommended in Aneded district and similar agro ecologies.

Influence of NPK Fertilizer on Growth and Nutrient Uptake of Kenaf (Hibiscuss Cannabinus L.) In South Western Nigeria (Published)
A pot experiment and field trial was conducted in 2013 and 2014 respectively at Ibadan (07038’N, 03084’E 182m) Nigeria to determine the influence of NPK fertilizer applied at five different rates (0, 70, 100, 130, 160 kg/ha) on the growth and yield of kenaf in a randomized complete block design with three replications. Our data showed that highest plant height, fibre and seed yields, and macro and micro nutrient uptakes were obtained in pots and plots fertilized with 130 kg/ha but not significantly different from those with 100 kg/ha. Hence, 100 kg/ha is recommended for kenaf cultivation in Southwest Nigeria.
