Abstract
This study aims to determine the effect of utilizing eggshell powder and chicken manure fertilizer on soil pH, phosphorus availability, and the growth of pakcoy plants (Brassica rapa L.). The study used a factorial Randomized Complete Block Design (RCBD) with two factors. The first factor was eggshell powder consisting of four levels: without eggshell powder, 15 g/polybag, 25 g/polybag, and 35 g/polybag. The second factor was chicken manure fertilizer consisting of three levels: 70 g/polybag, 105 g/polybag, and 140 g/polybag. Each treatment was repeated three times. The results showed that the eggshell powder treatment had an effect on soil pH and phosphorus availability. The treatment of 105 g/polybag chicken manure fertilizer had a significant effect on plant height at 2 and 4 weeks after planting (WAP), and also affected soil pH and phosphorus availability. The combination of eggshell powder and chicken manure fertilizer treatments also showed an effect on root weight and contributed to the increase in soil pH and phosphorus availability in the growth of pakcoy plants (Brassica rapa L.).

| Additional Information: | Tanah di Indonesia umumnya bersifat asam (pH 4,0–5,5) akibat curah hujan tinggi yang menyebabkan pencucian ion basa, sehingga menurunkan ketersediaan fosfor, unsur hara penting bagi tanaman. Kondisi ini berdampak pada pertumbuhan tanaman, termasuk pakcoy (Brassica rapa L.), yang produksinya mengalami penurunan dalam beberapa tahun terakhir akibat penurunan kesuburan tanah dan perubahan iklim. Fosfor yang terikat dalam senyawa tak larut menjadi kurang tersedia bagi tanaman, menghambat proses metabolisme dan pertumbuhan. Untuk mengatasi masalah ini, pemanfaatan bahan organik seperti tepung cangkang telur yang kaya kalsium karbonat dan kotoran ayam yang mengandung fosfor organik menjadi solusi potensial. Kedua bahan tersebut dapat meningkatkan pH tanah dan memperbaiki ketersediaan fosfor, sehingga mendukung pertumbuhan dan produktivitas pakcoy secara optimal. Penelitian ini bertujuan untuk mengetahui pengaruh dari pemanfaatan cangkang telur dan kotoran ayam terhadap kondisi pH, ketersediaan fosfor dalam tanah pada pertumbuhan tanaman pakcoy (Brassica rapa L.). | |||||||||
