| Abstract | ||||
| To determine the effect of phosphoric-P and K-humate on pea development under drip irrigation, a field experiment on pea under drip irrigation was conducted during 2020 to assess different combinations of phosphoric acid-P (P0, P1 and P2 of 0, 31 and 62 kg P ha-1) and humate-K (K0, K1, K2 and K3 of 0, 50, 75 and 100 kg K ha-1) given through drippers. The results demonstrated that the P62K100 treatment combination produced a high seed yield (3.66 Mg ha-1). The most efficient treatment for seed P uptake was to fertilize green pea plants with 62 kg P and 100 kg K per hectare. P62K100 had the maximum K uptake by seeds at 52.72 Kg ha-1. With rising K-humate and P-acid rates in low-fertility sandy soil and drip irrigation, yield of pods fresh weight increased. These results indicated that P and K interact in arid and infertile soil environments, and that employing unconventional sources enhances the growth and production of pea plants. | ||||
