Abstract

Ritonga ES, Istina IN, Usman U, Giri Wibisono MG. 2020. Adaptive study of upland new high yielding paddy locations specific in Riau province. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).New high yielding varieties (VUB) are one of the technology components that are easiest for farmers to adopt. Dissemination of VUB deployments runs relatively quickly when VUB can adapt well to an area, but not all VUB can give the same results in one particular location, including Riau. This study aims to obtain new high yielding varieties of upland rice which are adaptive in a specific site. The research was conduct in the dry land of Harapan Baru village, Mandau District, Bengkalis Regency from May to August 2020. The test used a randomized block design with five replications. The varieties used are Inpago 8, Inpago 9, Inpago 10, Inpago 11, Inpago 12 and Rindang. Parameters observed included plant height (cm), maximum number of tillers (stems), number of productive tillers (tiller), number of filled grains (grains), number of empty grains (grains), weight of 1000 grains (grams) and productivity (tonnes/ha). Data were analyzed using variance (ANOVA). If there was a difference in the 95% confidence level, the DMRT continued test performed. The results showed that Inpago 8 adapted to the environment and was able to provide the highest productivity (5.9 tonnes/ha) and gives the best preference by farmers.

Abstract

Paddy straw mushroom is high nutritious food matter, so it can be expected to be the best formulations of medium for optimizing growth. The objective of the research was to study the respon of Growth and Production of Paddy straw mushroom (Volvariella volvacea Bull. Ex. Fr.) toward formulations and thickness of mediums. This research was conducted in Plantation Education Institute Green House at Pancing, starting from February to March 2010. The method of this research is completely randomized design factorial with two factors and three replications. The first factor was the formulation of medium (M) consist of five levels. The second factor was the thickness of medium (T) consisting of two levels, 15 cm and 20 cm. The results of research showed that the formulation of medium significantly increase the number of mushroom body and fresh weight, but unsignificantly at start harvest time, length of mushroom body, cap’s diameters. Thickness of medium treatment and its interaction with formulation of medium unsignificanly at all parameters.

Abstract

Demand for rice tends to increase every year, while the increasing of production of food crops and horticulture are not comparable with the pace of population growth that has not sufficient for the needs of the population, especially for rice. Therefore, the government has attempted to improve production through intensification and intensification programs and the development of the new high yielding varieties. For example, the district government of Kuantan Singingi which has a high potential of agriculture was done dissemination plot of VUB (Inpari 1, Inpari 6 jete, Inpara 1, Air Tenggulang, and Gilirang) in five sub-districts (Kuantan Tengah, Kuantan Mudik, Benai, Kuantan Hilir, and Gunung Toar). The assessment was conducted in Kuantan Singingi district on July to September 2010. The results showed that Inpari 1, Inpari 6 Jete, Inpara 1, Gilirang, Air Tenggulang varieties 7.0, 6.75 , 6.0, 5.9, 5 ton/ ha in production, respectively. The Inpari 1 and Inpari 6 varieties are the highest production than production of other varieties. Both varieties were appropriate to be developed in Kuantan Singingi District.
