Abstract

The Growth and Production of Upland Rice Varieties Situ Bagendit In Different Planting Distance and Giving Straw Compost.  The aimed of this research to study the growth and production of upland rice varieties Situ Bagendit in different spacing and giving of straw compost. The research was conducted in the field UPT BBI, Tanjung Selamat at an altitude ± 57 meters above sea level since March 2012 until July 2012 using Randomized Block Design (RBD) factorial with two factors, which are the spacing (20 x 20 cm, 20 x 25 cm , 20 x 30 cm) and straw compost (0, 25, 50, 75, 100 g / planting hole). The parameters measured were plant height, number of tillers, straw dry weight, root dry weight, number of panicle, percentage of empty grain, the amount of grain productive, productive grain weight, grain 1000 grain weight, and grain production per plot. The results showed that the treatment of different spacing significantly affect the number of tillers 4-8 weeks after planting and root dry weight. Straw compost treatment significantly affect the number of tillers 4 weeks after planting, the percentage of empty grain and grain production per plot. The interaction between the different spacing and giving straw compost significantly affect grain production per plot.   Keywords : upland rice varieties situ bagendit, distance different plant, compost straw

Abstract

Growth and Yield Response of Three Sorghum Varieties (Sorghum bicolor (L.) Moench) onDifferent Soil Tillage. The aim of this research was to compare growth and yield of three varieties ofsorghum on different soil tillage. It was conducted at Pasar 1, Tanjung Sari, Medan about 25 mabove sea level on June to October 2012 by using Split Plot Design with two factors. The first factorwas sorghum variety (Sangkur, Kawali, Numbu) and the second one were different soil tillage (notillage, once tillage, twice tillage). The research land had sandy loam soil texture. The results ofresearch showed that growth and yield of Sangkur, Kawali, and Numbu weren’t effected by soiltillage treatment but without tillage treatment showed the best result. Numbu had better result onshoot dry weight (59.29%), biomass weight (59.37%), root volume (64.83%), yield per sample(59.42%), and 1000 grains weight (56.83%) compared with other varieties. The interaction betweensorghum variety and different soil tillage had no significantly effect on growth and yield of sorghum.Key words : Sorghum, variety, soil tillage, growth, yield

Abstract

ABSTRACTThis study aims to know the effect of weeding time on the growth and production of some varietiesof sorghum in Pasar 1 street Tanjung Sari, Medan, with ± 25 meters altitude above the sea level inJuly – November 2012. The design use Factorial Separated Design Frame with 2 aspects. The firstaspect as a main frame is variety (Sangkur, Kawali, Numbu) and the second factor as subordinateframe is weeding time (clean weeding during research, weeded after 7 days planting, weeded after 14days planting, weeded after 21 days planting, weeded after 28 days planting, without weedingprocess). The parameters measured were plant height, number of leaves, flowering, canopy wetweight, production per sample, production per plot, the production per ha, the weight of 1000 seeds.From the research, varieties significantly affect on plant height (4-8 weeks after planting), number ofleaves (6 and 8 weeks after planting), flowering, canopy wet weight, production per sample,production per plot, production per hectare, weight 1000 seeds.Weeding time significantly affect onplant height (4-8 weeks after planting) the number of leaves (2-8 weeks after planting), the weight ofthe wet canopy, production per sample, production per plot, production per hectare, the weight of1000 seeds. Interaction significantly affect on the number of leaves 6 weeks after planting.Keywords : sorghum, varieties, and weeding time

Abstract

Using of traditional medicine is growing rapidly at this time. Eleutherine americana Merr. is one ofkind plants that potentially can be traditional medicine. This research is proposed to find out theproper plant spacing and addition of rice straw compost of Eleutherine americana. This researchwas conducted at Jalan Pasar 1 Tanjung Sari, Medan with altitude ± 25 m above sea level from Mayto September 2013, using factorial randomized block design with two factors. The factors werevarious plant spacing (20x15, 15x10, 10x15 cm) and addition of rice straw compost (0; 0,5; 1kg/plot or 0, 10, 20 ton/ha) used three replications. Data were analyzed with ANOVA and continuedwith Duncan Multiple Range Test (DMRT). Parameters were observed sprouting age (day), heightof plant (cm), number of bulb per sample and fresh bulb weight per sample (gram). The resultsshowed that the plant spacing effected significantly on sproutig age, height of plant except 9-12weeks after planting, and the number of bulb per sample. Addition of rice straw compost notsignificantly on any parameters. The interaction of two factors effected significantly on height ofplant 4 and 5 weeks after planting.Keywords : Plant spacing, rice straw compost, Eleutherine americana Merr.
