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 (
o
C), 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).
