Rice is the staple food of Indonesia's population. Widespread food shortages in a country will lead to economic insecurity, social and political. Assemble new type of rice varieties for high yield, biotic and abiotic stress resistance, with good quality rice is a solution to cope with food shortages. Polinela been assembling some new strains of rice germplasm by using superior character in quantity and quality. Research purposes (1) Knowing what superior character possessed by a new strain of rice Polinela assemblies, (2) Knowing where the strain that has a high yield potential. The study was conducted in Polinela April to August 2012. Research conducted with Randomize Completly Block Design (RCBD). Treatment consisted of 10 new strains of rice assemblies Polinela 4th generation (F4), repeated three times. To know the differences between the treatment then continued with Least Significant Different (LSD) on stage 5%. The variables measured were: maximum plant height, maximum number of shoots, number of productive shoots, number of grains per panicle, number of filled grains per panicle, panicle length, grain 1000 grain weight, grain yield per clump, and grain yield per hectare. Organoleptic tests carried out on the aroma and texture of rice or rice flavor. Results showed (1) All new rice strains quantitatively Polinela assemblies have a high yield potential, which is between 7.4 tonnes /ha until 10:34 tonnes /ha, (2) Strain B3, D2, D3, F2, and F3 have high yield potential between 8.4 tons / ha to 10.3 t / ha, as well as having quality taste fluffier rice with a slightly fragrant aroma (rather sweet) until fragrant (fragrant).

The purpose of this study was to determine the growth and productivity of sweet corn on a Single Row, Double Row, Row Twins and Twins 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 : Single Row (SR) (20cm x 75cm), Double Row (DR) (20cm x 20cm x 80 cm), Twins Row (TR) (20cm x 10cm x 80 cm) , and TwinsSeed (TS) with plant spacing (40cm x 75cm two seed in one planting hole). Parameter observational studies high plants (cm), leaf number (cm), diameter (cm), lebar daun (cm) and long leaf (cm) and productivity (ton/ ha). 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) planting system gives a response was not significantly different in stem diameter and leaf length, the difference is shown in plant height, number of leaves and leaf width, 2) There is a significant differences in the productivity cropping systems. Twins Row cropping systems have different productivity with a Single Row planting system, Double Row, Twins Seed and (3) Average Twins Seed planting system showed the highest productivity of 39.42 ton/ha.
