Effects of combined application of phosphorus and sulfur fertilizers on agronomic traits and protein content of supplementary irrigated haricot bean (Phaseolus vulgaris) varieties in Raya Valley, Northern Ethiopia

The Effect of Elemantel Sulfur Fertilization on Green Beans (Phaseolus vulgaris L.) Grown in Calcareous Soil

“…In field trials conducted in Ethiopia in dry beans, it was found that the combination of 20 kg ha -1 P and 30 kg ha -1 S was the optimum ratio and maximum vegetative growth was achieved. It has been stated that it can be used to provide earliness and high grain yield for Melka Awash-98 variety (Teame et al, 2020).…”

“…Although the N concentration in the bean fruit decreased a little compared to the control, the amount of N taken by the plant from the soil increased (Table 4). Teame et al (2020) stated that the protein content with the effect of P -S fertilization in different bean varieties varied between 22.5-27.1%. With increasing doses of elemental S, the P concentration in bean leaves and fruit decreased significantly compared to the control (P<0.05), and S adversely affected the P concentration in the plant (Table 3).…”

“…It has been reported by various researchers that the applications of waste material containing elemental S and S provide a decrease in soil pH and an increase in usable nutrients in the trial soils (Kaya et al, 2009). In studies on elemental sulfur carried out in different countries (Hussain et al, 2011;Ganie et al, 2014;Teame et al, 2020), it was stated that positive results were obtained regarding the effect of sulfur together with other nutrients in bean yield and elemental content. Sulfur has many functions in plants and is a part of proteins and plays an important role in the synthesis of vitamins and chlorophyll in the cell (Marschner, 1995).…”
