Karakteristik Iklim Mikro Dan Produksi Jagung Manis Pada Beberapa Sistem Tanam
Abstract: The purpose of this
study was to determine the characteristics of the micro-climate (temperature,
humidity, and light intensity) and the production of sweet corn on a sigle row,
doble row, twin row, and Twin seed planting system. This study was conducted in
an experimental garden of Politeknik Negeri Lampung, Hajimena South Lampung, in
July-September, 2015. This study is based on randomized block design with one
factor cropping system consists of 4 treatment ie : Sigle Row (SR) (20cm x
75cm), Doble Row ( DR ) (20cm x 20cm x 80 cm), Twin Row (TR) (20cm x 10cm x 80
cm) , and Twin Seed (TS) with plant Spacing (40cm x 75cm 2 seed in one planting
hole). Parameter observations of this study consisted of (1) micro-climate
(temperature (oC), relative humidity (RH %) and Interception of Light (%) ) and
(2)production (corn length (cm) , corn diameter (m ) and Corn weights (grams).
The data were analyzed using the F test at
1 % and 5 % level and than followed by test BNT. The conclusion of this
study were (1) The characteristics of the microclimate : a) There is a
noticeable difference in the temperature of the top of the current crop of 4
mst and at 9 mst there is a significant difference in the temperature of the
bottom , where SR has a different temperature involves the other b) All systems
planting has a relative humidity (%) were not significantly different , and c )
there is a difference light interception ( % ) during the day when 4 mst , where
the twins seed has a light interception is different from other treatments and
there is a difference light interception during 9 mst where sigle row has a
different light interception to other treatments. (2) The production of sweet
corn on the treatment SR, DR, TR and TS were not significantly different and
has a weight of corn (SR = 354.8 grams, DR = 316.5 grams, 328.5 grams TR and TS
= 325.4 grams) same with description bonanza varieties (270-300 grams).
