Abstract
[MANURE APPLICATION AS A SOIL AMENDMENT TO PROMOTE GROWTH AND YIELD OF MELON (Cucumis melo L.) IN ULTISOL]. The application of manure may overcome soil fertility problems in Ultisol triggered by low pH, high P retention, high content of Al and Fe, and low CEC. The objective of this study was to determine the optimum dose of different manures applied to promote the best growth and yield of melon. The study was conducted from February to May 2019 at the Experimental Plot of the Faculty of Agriculture, University of Bengkulu. Three different manures (chicken, cow, and goat manure) were applied at 5, 10, 15, and 20 tons/ha. These treatments were arranged in Completely Randomized Design with three replications. The results show that the enhancement in chlorophyll content (SPAD index) was highest in plots solely applied with 20 tons ha-1 manure, whereas application of manure even at 20 tons/ha had no effects on melon yield and its components. Manure types solely promoted plant height, maturity date, fruit diameter, and soluble solid content (Brix). Melon growth and yield were not affected by combined application of manure type and dose. These indicate that application of manure types irrespective of the amount applied failed to solve fertility problems in Ultisol where melon was grown.

Summary
ABSTRACT [MANURE APPLICATION AS A SOIL AMENDMENT TO PROMOTE GROWTH AND YIELD OF MELON (Cucumis melo L.) IN ULTISOL]. Hasil penelitian menunjukkan bahwa peningkatan kandungan klorofil (SPAD indeks) tertinggi di petak percobaan yang diberi pupuk kandang 20 ton/ ha, sedangkan perlakuan ini tidak meningkatkan hasil melon dan komponennya. Hal ini menunjukkan bahwa aplikasi jenis pupuk kandang terlepas dari jumlah yang diberikan gagal untuk menyelesaikan masalah kesuburan tanah di Ultisol dimana melon ditanam. Salah satu upaya untuk meningkatkan produktivitas tanah ultisol dengan pemberian pupuk organik maupun pupuk anorganik yang cukup agar pertumbuhan dan produksi dapat meningkat. Pupuk kotoran sapi sifatnya lebih baik dari pada pupuk alam lainnya maupun pupuk buatan, karena merupakan humus yang mengandung senyawa-senyawa organik dan merupakan sumber unsur hara makro yang penting bagi pertumbuhan dan perkembangan tanaman (Mayun, 2007). Penelitian ini bertujuan untuk menjelaskan interaksi antara jenis pupuk kandang dengan dosis pupuk kandang terhadap pertumbuhan dan hasil tanaman melon serta dosis optimum pupuk kandang yang dapat memberikan pertumbuhan dan hasil tanaman melon terbaik
