Abstract

Borneo Prima Mandarin (Citrus reticulata cv Borneo Prima) is a new local commodity that grown in lowland but has an interesting orange skin. As a new commodity, Borneo Prima Mandarin has to be developed in order to reduce citrus import. The research was conducted in lowland area (250 m above sea level) IPB research station, Sindang Barang, Bogor from February 2014 to February 2015. The aim of this research was to observe the effect of phosphorus and potassium (PK) fertilizer and pruning on the growth and performance of the plants. This research used Randomize Complete Block Design (RCBD) with two factors. The first factor was aplication of PK fertilizer (15 g P+ 10 g K, 15 g P+ 15 g K, 20 g P+10 g K, 20 g P+15 g K per plant) and the second factor was pruning form (without pruning, open center pruning and hedge pruning). The result showed that the combination of phosporus and potassium fertilizer just gave a significant effect to number of shoot. The highest number of new shoots formed by fertilizing 15 g P+10 g K per tree per application. Pruning treatments had significant effect to plant architecture (i.e reduce plant height, land occupation). Open center pruning and hedge pruning made the crown more open that can increase the light interception so that increase the rate of photosynthesis.

Abstract

Tomat merupakan salah satu tanaman sayuran penting di Indonesia. Penggunaan pupuk organik cair lamtoro dapat menjadi alternatif dalam menekan penggunaan pupuk anorganik dan memperbaiki kondisi lingkungan.  Penelitian ini bertujuan untuk mendapatkan konsentrasi pupuk organik cair lamtoro dan interval waktu aplikasi terbaik untuk pertumbuhan dan hasil tanaman tomat. Penelitian telah dilaksanakan di lahan percobaan dan Laboratorium Agronomi, Fakultas Pertanian dan Peternakan, UIN Sultan Syarif Kasim Riau. Percobaan menggunakan Rancangan Acak Lengkap (RAL) dengan dua faktor, yakni konsentrasi pupuk organik cair lamtoro (0, 10, 20, 30%) dan interval waktu aplikasi (3, 6 dan 9 hari). Hasil penelitian menunjukan bahwa pupuk organik cair lamtoro dengan konsentrasi 10% efisien untuk meningkatkan tinggi tanaman, diameter batang dan jumlah buah per tanaman. Interval 9 hari memberikan hasil terbaik terhadap parameter tinggi tanaman, jumlah daun dan diameter batang. Tidak terdapat interaksi antara perlakuan konsentarsi dengan waktu aplikasi pupuk organik cair daun lamtoro.Kata kunci: konsentrasi, lingkungan, organik, pupuk, sayur
