The experiments were arranged in a randomized complete block design with three replications on six farmers’ fields. Treatments included nine levels of nitrogen fertilizer. The nitrogen source was Urea Stabil, which is slow N releasing fertilizer and conventional urea at recommended rate was included. The results of the study revealed that plant height, spike length, grain and biomass yield, thousand grain weight, moisture content were significantly affected by nitrogen levels, but harvest index and hectoliter weight can’t show significance affects at different nitrogen levels. The maximum plant height, spike length, grain and biomass yield (90.42cm, 7.48cm, 4079.0kg ha and 9748.3 kg ...

For this reason, the experiment was carried out to determine the effect of organic and inorganic fertilizer application on yield and yield components of malt barley at Welmera District. The experiment was laid out in randomized complete block design with three replications. Analysis of variance showed significance difference among treatment for most yield and yield component. The highest plant height (103.5 cm) and spike length (7.9 cm) and the highest biomass yield (12793 kg/ha) and grain yield (3558.5kg/ha) were recorded from the combination of 50% vermicompost with 50% of recommended NP. The highest net benefits (41843 Birr/ha) with marginal rate of return (14802.1%) was recorded at 50% N/P O rates of 30/34.5 kg 2 5 ha combined with 50% (20.5qu ha ) vermicompost fertilizer. Therefore, to maintain soil fertility and to 1 1 increase yield productivity, ap...

Fertilizer treatments were applied at planting and soil samples were collected three weeks after planting to analyze Olsen extractable phosphorus which is correlated to relative chickpea grain yield and determine the critical soil phosphorus level (by using Cate-Nelson graph method) and phosphorus requirement factors of chickpea on vertisols accordingly it was determined as 11.9 mg kg of soil and 8.97 mg kg , respectively. From the aggregate mean data analysis result 1 1 the highest chickpea grain yield, biomass yield and other related yield components was obtained from 30 kg P ha application rate with 20 kg starter Nitrogen ha , 7 kg Sulfur ha and 0.51 Kg Boron ha. The least 1 1 1 1 result in all parameters was obtained from control treatment which has 0 P level.
