Pertumbuhan dan Keragaan Tanaman Jeruk Keprok Borneo Prima pada Dosis Pupuk dan Bentuk Pangkas Berbeda
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.
