Pengaruh Jenis dan Tingkat Kerapatan Gulma Terhadap Pertumbuhan dan Produksi Tanaman Sorgum (Sorghum Bicolor L.)
Abstract: Sorghum is one of
serealia plants that have a big potential to be developed. Sorghum is
beneficial as a source of food, animal feed, as well as various industrial raw
materials. Sorghum is potential to be developed with the application of proper
cultivation, one of them is optimal maintenance. The lack of maintenance cause
low production. One of maintenance is weed control. Weeds can create a
competition with cultivation plants to fight means growing. Type and weed
density are influence growth a development of sorghum. The purpose of this
research is to know: (1) The influence of type of weeds to growth and
production of sorghum plants, (2) The influence of weeds density to growth and
production of sorghum plant, and (3) There is interaction between type and
weeds density when influence the growth of weeds, also growth and production of
sorghum plants. This research is done in South Lampung and weeds laboratory
University of Lampung on December 2014 - April 2015. Treatments arranged in a
factorial strip plot design with three replications. The first factor is three
types of weeds, that are Asystasia gangetica, Cyperus rotundus, and Rottboelia
exaltata. The second factor is density 0, 10, 20, 40, and 80 weeds/m2. If
assumption are met, the data is analyzed by using variance analysis and
followed by a least significant difference (LSD) 5%. The result shows: (1) The
type of weeds influence growth and yield component of plant height and steam
diameter 3 WAP, fresh weight and dry stover, also weight of 100 grains on water
content) WC14%, (2) The density of 80 weeds/m2 influence the height a plant 3
and 9 WAP, number of leaves 6 MST, steam diameter 3, 6, and 9 WAP, weight of
fresh stover plant, weight of 100 grains on water content 14%, weight of
sorghum seed, and (3) There is no interaction between the type and weeds density
when influence growth and sorghum production, but there is interaction when
influence the growth of weeds.
