Abstract

As an effort to overcome problems in rice cultivation system, it is necessary to use new technologies and innovations. This study aims to determine the physical and nutritional quality of grain and milled rice from 2 varieties of rice using several planting systems. The research was conducted using a Completely Randomized Design of factorial pattern, consisting of 2 factors with 3 replications. The factors were: a) Planting system (S1 = Cubic S2 = Double row 2: 1, and S3 = Twin seed) and b) Rice varieties (V1 = Ciherang; V2 = Inpari 10). The observation parameters include: physical quality of grain, rice milled quality, physical quality of rice and rice nutrition. The results showed that the cubic planting system produced a higher empty grains than the double row and twin seed planting system. The twin seed planting system, yielding lime green grains and yellow broken grains lower than other planting systems, both on rice varieties of Ciherang and Inpari 10. Grains from Ciherang variety had a thinner shell and a higher hardness level of rice compared to grain of Inpari 10 variety, resulting in higher milled rice and head rice, but lower in broken rice and rice groats contents. It can be concluded that: a) the physical quality of rice was not affected by the planting system, but it was significantly affected by the rice varieties; b) the planting system and rice varieties used in this study did not have significant effect on the nutritional quality of the rice produced.

Highlights

As an effort to secure the national food and to achieve the national production target, an appropriate way of cultivation is needed, such as through the arrangement of planting spacing
The spacing will affect the quality of growth of clumps of plants in the field[1]. This is in line with the results of Hatta's2 study indicating that plant spacing has significant effect on the number of productive tillers, but has no significant effect on panicle length and yield per hectare
The low agricultural productivity in Indonesia is currently due to various factors, one of which is the use of improper plant spacing, i.e. the cubic planting system

Summary

Introduction

As an effort to secure the national food and to achieve the national production target, an appropriate way of cultivation is needed, such as through the arrangement of planting spacing. Biotype 1 and 2, b) realtively resistant to bacterial leaf blight strains III, c) rather susceptible to the blight of bacteria strain IV leaves, d) can be planted during the rainy and dry seasons and well planted on paddy fields with 5-7 days irrigation system, e) the harvest age is at 112 days, f) productivity potential is 7 tons/ ha, g) has a slender form of grain and h) the flavor of rice is waxy, so it is favored by consumers[11] This reserach aims to investigate the physical and nutritional quality of grain and milled rice using two rice varieties (i.e. the Ciherang and Inpari 10), with three different planting systems (i.e. the cubic, double row and twin seed)
