Abstract
Introduction and purpose: The careless use of chemical fertilizers has led to numerous environmental issues. A key strategy to reduce reliance on chemical fertilizers and mitigate their adverse effects is the application of organic fertilizers.
Materials and Methods: The factorial experiment was conducted using a randomized complete block design (RCBD) with three replications during 2022. The first factor consisted of three levels of supplemental irrigation and the second factor was three levels of organic fertilizers.
Results: The resultdns showed that in comparison to no irrigation, once and twice supplementary irrigation decreased the contribution of total plant in grain yield by 15.1% and 43.2%, respectively. When supplementary irrigation is applied once, as opposed to without irrigation, the digestible dry matter, total digestible nutrients, and net energy for lactation increase by 3.1, 2.4, and 2%, respectively, and when it is applied twice, the increases are 4.3, 5.1, and 4.2 percent, respectively. When compared to no-fertilizer conditions, the use of animal manure and vermicompost reduced the contribution of total plant in grain yield by 38.9% and 44.3%, respectively, while increasing dry matter intake by 3.9% and 14.1% and relative feed value by 3 and 14.2%. Additionally, under non-irrigated conditions, the use of vermicompost and animal manure increased grain yield by 99% and 106.8, respectively, over the absence of fertilizer.
Conclusion: The findings suggest that supplemental irrigation and the use of organic fertilizers can significantly enhance the yield and quality of fodder in pea plants cultivated in rainfed conditions.
