Effects of Different Level of Phosporous Fertilizer on Yield and Yield Component of Field Pea (Pisum sativum L.) Varieties in Hadiya Zone Duna Area Southren Ethiopia

Field pea with other food legumes covers about 11-15% of the total 6-7 million hectares of crop areas in Ethiopia and is the third most important stable food legume among the highland pulses in rural Ethiopia but the lack of nutrient for plant growth in many soils limit crop production in Ethiopia and to study this problem a field experiment was conducted at Latabo farmers training centre to evaluate the effect of different level of to phosphorous (0, 23, 46, and 69 kg ha-1) with four types of field pea varieties: Local Tegegnech, Burikitu and Wolimera combined in RCBD. Data grain yield and yield components were recorded during specific physiological stages. The effect of phosphorous was significant in hastening physiological maturity of crop, and its effect was significant on flowering and growth parameters. The grain yield ranged between 2.43 tone ha-1 at 0 kg phosphorous ha-1 and 2.67tone ha-1 at application of 69kg phosphorous ha-1. Besides, total biomass was also significantly influenced by phosphorous and ranged between4.4 tone ha-1 at control to 4.87tone ha-1 at rate of 69 kg phosphorous ha-1.The highest phosphorous use efficiency (48.3%) was obtained at 69 kg phosphorous ha-1 and increased with increasing rates of phosphorous application, whereas apparent phosphorous recovery was found to be highest at 46 and 69 kg phosphorous ha- 1repectively. Both agronomic and physiological phosphorous use efficiencies of the crop were highest at the rate of 69 kg phosphorous ha-1.a. Therefore, Wolimera and Birukit with application of 69 kg phosphorous ha-1 are recommended for field pea production at Duna area.
