Effects of Sheep Manure and Di-ammonium Phosphate on Soybean Growth, Photosynthesis, and Yield under Parwan Agro-climatic Conditions, Afghanistan

Öz

Climate change, with its rising summer temperatures, colder winters, and erratic rainfall, is severely impacting calcareous soils in arid and semi-arid regions, leading to escalating nitrogen and phosphorus deficiencies. Limited studies investigated the effects of sheep manure (SM) and di-ammonium phosphate (DAP) on soybeans under calcareous soils. In this study, the fertilizer treatments (FT) were FT1 (SM = 0%, DAP= 0%), FT2 (SM= 100%, DAP= 0%), FT3 (SM = 0%, DAP= 100%), FT4 (SM = 50%, DAP= 75%), FT5 (SM = 50%, DAP= 50%), and FT6 (SM = 50%, DAP= 0%) elucidated on attributes of soybean cv. LD 04-13265 USD under calcareous soil conditions. The FT4 and FT5 treatments, combining sheep manure (SM) and di-ammonium phosphate (DAP), significantly enhanced net photo-synthetic rate, stomatal conductance, transpiration rate, and water use efficiency com-pared to the control (FT1). While all fertilization treatments resulted in lower intercellular CO2 concentrations than the control, the combined applications of SM and DAP (FT4 and FT5) demonstrated superior growth performance, higher photosynthetic efficiency, and increased seed yield. Although plant height and nodule number remained unaffected by fertilization, other growth parameters, including leaf number, root length, and shoot biomass, were significantly influenced. There was a positive correlation between seed yield and root length (r = 0.90), photosynthetic rate (r = 0.86), shoot biomass (r = 0.82), and water use efficiency (r = 0.76). Furthermore, the FT4 and FT5 treatments showed the highest seed yields, increasing by 81.3% and 64.3%, respectively, compared to their control. The combined use of sheep manure and DAP significantly contributes to high soybean yields, offering an eco-friendly alternative to the excessive use of chemical fertilizers and increasing the income of soybean crop producers.
