PENGARUH PUPUK KANDANG AYAM YANG DIPERKAYA PGPR TERHADAP pH DAN P-TOTAL SERTA HASIL TANAMAN TOMAT (Solanum lycopersicum L.) PADA TANAH ULTISOL

Abstract

The purpose study aimed to determine the effect of chicken manure added with PGPR on soil pH and total-P and yield of tomato (Solanum lycopersicum L.) on Ultisol soil. The research was performed in Experimental Land 2, while soil analysis was carried done at the Nanoscience Technology Laboratory and the Soil Science Laboratory, Halu Oleo University. The trial took place from November 2021-September 2022. This study used a Randomized Block Design (RBD) consisting of 4 treatments of chicken manure, namely KO = without of chicken manure added with PGPR serves as control, K1 = 200 g polybag-1, K2 = 400 g polybag-1, K3 = 600 g polybag-1 each treatment was added with 400 ml of PGPR from bamboo roots. The results indicated that the higher of chicken manure applied, the higher of the the total-P and soil pH as well as the plant growth. The application of 600 g polybag-1 increased soil pH and total-P 28,93 mg 100 g-1 and 6,4, respectively. It was also observed that the application of 600 g polybag-1 of chicken manure (K3) recorded the highest plant by 120.66 cm, the highest number of branches by 11.66 and the number of fruits was 3.66 as well as the heaviest fruit weght by 145.33 g.
