RESPON TIGA VARIETAS PADI (Oryza sativa L.) PADA BERBAGAI SISTEM TANAM LEGOWO

Abstract

This research was conducted in Village S. Mallori, Sub District Dua Pitue, Sidrap Regency
which lasted from May to August 2015. This study aims to determine the growth and production of
rice varieties Mekongga, Inpari 14 and Inpari 30 on some legowo planting system. This research
was conducted based on Split Plot Design. As the main plot is legowo consisting of four cropping
systems, namely tiles (30 cm x 30 cm), legowo 2: 1 (40 cm x 15 cm x 15 cm), Legowo 3: 1 (40 cm
x 15 cm x 15 cm), and Legowo 4: 1 (40 cm x 15 cm x 15 cm) while the subplot is a variety consisting
of three varieties namely Mekongga, Inpari 14 and Impari 30. There are 12 treatment combinations
which are replicated 3 (three) times so that overall there are a total of 36 plot total experiments.
The results showed that the use of different planting systems significantly significantly affected the
growth and production of rice crops with the best results shown by tile planting system (30 cm x
30 cm) on the parameters of the number of productive tillers of 16.41 stems, the number of grains
46
per panicle 178.31 grains, and panicle density of 7.02 grains.cm-1. However, the highest yield of
grain per hectare was shown by the planting of legowo 2: 1 and legowo 3: 1 systems, ie 6.38 and
6.33 tons GKP.ha-1, respectively. Inpari 14 varieties gave the best results on the parameters of
number of productive tillers (11.22 stems), panicle length (25.99 cm) and percentage of unhulled
grain (85.65%), and empty grain (14.34%). There is no interaction between the treatment of
planting systems with varieties on the growth and production of good rice crops
