The Response of Growth and Production of Saveral Varieties of Brown Rice Gogo (Oryza Nivara L.) with Different Planting Distance

Abstract

This research was conducted at sungei Putih Research Institute. Galang, Jl. Sei Putih Rispa, Deli Serdang Regency, North Sumatra, from September to February 2021. This study was conducted using a Divided Tile Design (RPT) consisting of 2 treatment factors, namely: 1). Various Types of Varieties (notation V) consisting of 4 levels of treatment, namely: V1 = Sigambiri Merah; V2= MSP 17; V3= Hamparan Perak; V4= Kambiri Lumat. 2). Various treatment distances consisting of 4 levels of treatment, namely: J1= 20 x 20 cm; J2= 25 x 25 cm; J3= 20 x 30 cm; J4= 20 x 40 cm with a height of 80 meters above sea level. The parameters observed in this study are the height of plants, the number of samples, the intensity of locust pest attacks, the intensity of pest attacks of walang sangit, the age of flowering, the number of malai per sample, the number of malai per plot, the weight of dry grain harvest per sample, the weight of dry grain harvest per plot, the weight of 1000 grains of grain. The results obtained in this study are: 1). The provision of various types of varieties has a real effect on the height of plants, the number of samples, the intensity of pest attacks walang sangit, flowering age, the number of malai per sample, the number of malai per plot, the weight of dry grain harvest per sample and the weight of dry grain harvest per plot, but has no noticeable effect on the intensity of locust pest attacks and the weight of 1000 grains of grain. V2 treatment results in the highest number of sapds. 2). The provision of various planting distances has a real effect on the height of plants, the number of samplings, the age of flowering, the number of malai per sample, the number of malai per plot, the weight of dry grain harvest per sample and the weight of dry grain harvest per plot, but has no noticeable effect on the intensity of locust pest attacks, the intensity of pest attacks walang sangit, flowering age and weight of 1000 grains of grain. The treatment of planting distance of 20 x 30 cm can increase the growth and production of brown rice gogo plants.
