Online Published on 20 August, 2022. Abstract This study aimed to assess fatty acid composition, seed yield, and morphological characteristics of two fodder pea genotypes depending on different doses of phosphorus application. The highest number of pods plant−1 (27.66-28.00), pod length (6.37-6.47 cm) and 1000 seed weight (126.12-126.42 g) were recorded at 60, 90and 120 kg P2O5 ha−1 treatments. The main stem length and the number of seeds pod−1 ranged from 119.77 to 122.00 cm and 6.11 to 6.22, respectively, in fodder pea genotypes at all P2O5 treatments. In fodder pea genotypes, the highest seed yield was recorded (2.51, 2.49 and 2.51 t ha−1) at three doses (60, 90 and 120 kg P2O5 ha−1). Fatty acid compositions did not differ among the fodder pea genotypes. Application of 60 and 90 kg P2O5 ha−1 increased the myristic (0.19%), palmitic (17.03-17.05%), heptadecanoic (0.20-0.22%), stearic (7.13-7.14%), oleic (16.39-16.42%), linoleic (59.96-60.21%)and linolenic acid (11.03%) contents of fodder pea seeds. Application of 60 kg P2O5 ha−1 was, therefore, recommended for high seed yield and myristic, palmitic, heptadecanoic, stearic, oleic, linoleic and linolenic acid contents in fodder pea under subtropical conditions.
