Abstract

Ritonga ES, Istina IN, Maizar M. 2019. The performance of the c type of swamp rice line through ratoon technology at Rokan Hilir Regency. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):220-229.  To support food security, the government set a national rice production target of 10 million tons in 2014. Its a trigger in agricultural innovation. The utilization of sub-optimal lands such as tidal lowland for the purpose of increasing food production and self-sufficiency and making swamps as a national food barn continue to be pursued, both through innovation and excavation and the development of local wisdom. Various technological innovations have been produced by the IAARD on tidal lowland, including increasing crop intensity (IP), genetic improvement in rice, and ratoon planting systems. The aim of this research was to get the type C tidal rice lines through ratoon technology. The research has been conducted at Pematang Sikek Village, Rimbo Melintang sub District, Rokan Hilir Regency with  C type of tidal lowland using a Randomized Group Design with 4 replications. The rice strains tested included 11 tidal rice were with 11 types of tidal rice lines (G1, G3, G4, G6, G7, G8, G17, G20, G23, G45 , G53). The results showed that the best vegetative growth were G3 (118.33 cm), G7 (15.00 stems) Number of productive tillers was G4 (15.33 stems) while for generative growth G4 (2.50 t / ha), G53 ratoon (35.33 cm) 238.00 gram), weight of a thousand grains of G53 ratoon was (26.77 gram). G4 gives the highest production and adapted to Rokan Hilir tidal lowland.

Abstract

Nurhayati N, Usman U, Ritonga E, Istina IN.  2020.  Development Potential soybeans intercropping in immature palm oil at 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).Indonesian soybean production has only fulfilled 56% of national needs. Soybean production can still be increased through the application of technological innovations to increase productivity and utilization of immature oil palm plantations. The area of oil palm plantations in Riau continues to expand from 2.01 million ha in 2016 to 2.7 million ha and 2018. Soybean development in oil palm plantations can be done, on immature plants, mature plants and damaged crops land with a potential area of 821,067 ha. Efforts to develop soybeans in oil palm plantation areas with shade-tolerant soybean VUB technology, improvement of soil fertility through amelioration, organic fertilizers and N, P and K. fertilizers can contribute to the fulfilment of soybean needs at least 17.10% of the national requirement.

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.
