Abstract

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).

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 anexperimental garden of Politeknik Negeri Lampung, Hajimena South Lampung, in July-September, 2015. This study is based on randomized block design with one factor croppingsystem consists of 4 treatment ie : Sigle Row (SR) (20cm x 75cm), Doble Row ( DR ) (20cm x20cm x 80 cm), Twin Row (TR) (20cm x 10cm x 80 cm) , and Twin Seed (TS) with plantSpacing (40cm x 75cm 2 seed in one planting hole). Parameter observations of this studyconsisted of (1) micro-climate (temperature (oC), relative humidity (RH %) and Interceptionof 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 bytest 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 andat 9 mst there is a significant difference in the temperature of the bottom , where SR has adifferent temperature involves the other b) All systems planting has a relative humidity (%)were not significantly different , and c ) there is a difference light interception ( % ) duringthe day when 4 mst , where the twins seed has a light interception is different from othertreatments and there is a difference light interception during 9 mst where sigle row has adifferent light interception to other treatments. (2) The production of sweet corn on thetreatment 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 withdescription bonanza varieties (270-300 grams).Keywords : Cropping Systems , Micro Climate , Production

Abstract

The purpose of this study is to know the characteristics of microclimate and the growth ofcorn and soybean on single row, doble row, twin row, and twin row seed system inpoliculture and monoculture pattern. The research was arranged in Randomized BlockDesign with two factors (1) planting system consisting of 4 treatments (Sigle Row (SR) (25x75cm) Doble Row (DR) (20x 20x 80cm), Twin Row (TR) (20x10x 80 cm), and Twin Seed (TS)(40 x 75cm (2 seed in 1 planting hole)) and (2) Cropping Pattern (Polikulture (TS) (100 cmof corn line distance)) and monokulture (TT), with 3 replications. Data analysis was doneby F test (1% and 5%) and BNT (5%). Conclusions: Microclimatic characteristics (a) LightInterception (%) at morning of middle plant canopy, midday and afternoon in the middle andlower part of the canopy are not significantly different. There is a significant difference inmorning light interception at the bottom of the plant canopy, the lowest light interception isTTSR treatment. Temperature (oC) there was significant difference of temperature due to treatment. the TTTS treatment had the highest average temperature under the plant canopy(26.30 o C) and the center of the plant canopy (29.40 o C). Relative humidity (%) did not give a significantly different response to the treatment.
