Comparison between amino acids and chemical fertilizers in terms of their effect on growth and yield traits of peas (Pisum sativum L.)

A field experiment was conducted during the 2024-2025 agricultural season in the fields of the Department of Plant Production Techniques/Agricultural Technical College/ Northern Technical University. experiment was conducted using a complete randomized block design, with 12 experimental units. the experiment included one factor: four levels of fertilizer (no fertilizer for comparison purposes, N.P.K chemical fertilizer, organic fertilizer with amino acids, and a treatment mixing chemical fertilizer and amino acids). plants were sprayed twice, the first time at the 3-5 true leaf stage, and the second time 15 days after the first spray. results showed that the mixed treatment was superior to the other treatments in all traits, plant height, number of branches per plant, pod length, number of seeds per pod, weight of 100 seeds, and seed yield kg. dunum-1 and biological yield kg. dunum-1, which reached values of 88.45 cm 7, 12.78 cm, 11, 17.89 g, 387.50 kg. dunum-1 and 83625 kg. dunum-1, respectively.
