Abstract

Plant growth regulators have a significant impact on increasing both quality and quantity of plant yield for either mixed or separated application. The research was aimed to identify the effect of spraying  plant growth regulators on duku flowers for fruit formation. The research was conducted from December 2014 to May 2015 in Sijacarana Local Technical Implementation Unit (UPTD) of Propagation, South Sumatra Province in Ogan Komering Ulu (OKU) Timur Regency. Duku tree used was 15 years old with the height around 10 meter. Complete Randomized Design was used with 3 replications where duku trees as the replicates. The spraying  consisted of 3 single plant growth regulator treatments and 6 mixed treatments which were P1 (BAP 300 mg.L-1), P2 (NAA 300 mg.L-1), P3 (GA3 300 mg.L-1), P4 (BAP 100 mg. L-1 + GA3 200 mg.L-1), P5 (BAP 200 mg.L-1 + GA3 100 mg.L-1), P6 (BAP 150 mg.L-1 + GA3 150 mg.L-1), P7 (NAA 100 mg.L-1 + GA3 200 mg.L-1), P8 (NAA 200 mg.L-1 + GA3 100 mg.L-1), P9 (NAA 150 mg.L-1 + GA3 150 mg.L-1). Spraying was applied twice with a half dosage for each application. First application was performed about one month after flowering, and the second was one and a half month after flowering. Data were analyzed using analysis of variance and least significance difference at α 5%. The measurement of parameters were carried after harvest or 3 months after treatment. Results showed that plant growth regulator positively affected duku fruit formation. GA3 treatment then was considered as the best treatment as it had a unison in fruit maturity, the highest number of fruit per bunch, weight per fruit and total fruit weight per bunch, and had the lowest number of green fruit and seed per fruit.

Abstract

Penelitian ini bertujuan untuk mendeterminasi pertumbuhan benih berkecambah Kelapa Sawit pada media topsoil diaplikasi kompos eceng (Monochoria vaginalis) maupun pupuk organik cair tebu pada pembibitan awal. Penelitian dilaksanakan di Kebun Percobaan Fakultas Pertanian, Universitas Sriwijaya. Penelitian ini terdiri atas 2 penelitian yaitu Penelitian A dan Penelitian B. Penelitian A adalah perlakuan berat Kompos Eceng dicampur media topsoil dengan design RAK dengan 7 perlakuan, 3 ulangan. Penelitian B adalah perlakuan volume Pupuk Organik Cair pucuk Daun Tebu (POC diaplikasi 4 ml  tanaman-1minggu-1) dengan design RAK dengan 4 perlakuan, 5 ulangan. Respon bibit tanaman kelapa sawit terhadap pemberian kompos (organik padat) maupun POC (organik cair) menunjukkan  pada 6 minggu setelah tanam merupakan sebagai fase tumbuh yang tepat untuk mengaplikasikan POC lewat tanah sebanyak 4 ml POC tanaman-1 minggu-1 dengan awal aplikasi seminggu setelah tanam. Respon tanaman kelapa sawit terhadap pemberian organik berupa POC lewat tanah lebih ditunjukkan oleh pertumbuhan tinggi bibit tanaman. Kompos Eceng sebanyak 300 g tanaman-1 dicampurkan media top soil menghasilkan jumlah klorofil daun yang lebih banyak.
