Quality of Snap Bean (Phaseolus Vulgaris L.) as influenced by N and P Fertilizer Rates at Jimma Southwestern Ethiopia

Abstract

Wastes produced from sugarcane industries are organic in nature, and it augmented the soil properties as well as improves crop yield and quality. In 2016 field experiment was conducted to investigate effect of filter cake and bagasse for nitrogen and phosphorus use efficiency of upland rice grown on calcareous sodic soils of Amibara District. The result revealed that plant nutrient use efficiency indices agronomic efficiency, agrophysiological efficiency and apparent recovery efficiency of both nitrogen and phosphorus were significantly (P<0.05) affected by the application of filter cake and bagasse. The maximum nitrogen was recovered at 20 t ha -1 filter cake followed by combined application of 10 t ha -1 bagasse + 20 t ha -1 FC that gave 45.10 % from kg quantity of nitrogen uptake per unit of kg nutrient applied. But, the minimum nitrogen recovery efficiency was recorded at 20 t ha -1 bagasse + 20 t ha -1 filter cake. The Phosphorus apparent recovery efficiency ranged from 18.55-32.91 %. The interaction of filter cake with bagasse also highly significantly (P < 0.01) affected rice grain yield. It can be encouraged to use these wastes with combination of inorganic chemical fertilizers under various cropping systems to enhance nutrient availability to plant under calcareous sodic soil.

Snap Bean (Phaseolus vulgaris) Response to Deficit Irrigation and Nitrogen Fertilizer and Relationships between Yield, Yield Component, and Protein Content

“…e current outcome aligns with that of Ref. [53], the application of 123 kg nitrogen per hectare produced the maximum marketable pod production and was statistically equivalent to the application of 82 kg nitrogen per hectare under full-irrigation conditions. Ref.…”

Review on effect of N and P fertilizer rates on yield and yield components of common bean [Phaseolus vulgaris (L.)] varieties

“…Common bean is also one of the most important cash crops and source of protein for farmers in many lowlands and mid-altitude zones. The country's export earnings is estimated to be over 85% of export earnings from pulses, exceeding that of other pulses such as lentils, faba bean and chickpea (Fissha and Yayis, 2015) [23] . National average yield of common bean in Ethiopia was 1.70 tons ha -1 and totally 520,979.33 tons yield was produced from 306,186.59 ha of land in 2017/18 cropping season (CSA, 2018) [14] .…”

Nutrient use and recycling in urban, peri-urban and rural farms in Ethiopia

“…In Addis Ababa, N output, partial N balance (PNB), gross margin of livestock (GML) and net farm income (NFI) were positively correlated to total N input (Table 3. 6). PNB was positively correlated to GML and NFI.…”
