STUDY OF AGRONOMIC TRAITS IN LOCAL RICE OF WETLAND SWAMP DISTRICT BATANGHARI IN JAMBI PROVINCE
Keywords:local rice, swampy land, agronomic traits
AbstractSwamp Â land is one of the areas of agricultural Â development Â that is perspective Â where the agroecosystem Â has the characteristics, Â and very unique with specific inundation and soil properties compared to other agroecosystems. Â At present, in some of these areas rice cultivation Â is still using local varieties. Local Â rice is one of the genetic resources which is quite diverse. The ability to adapt to extreme environments Â is the reason for most farmers to continue to plant and cultivate local Â rice. The study of the agronomic traits of local rice in swamp land is carried out in order to see the agronomic character and obtain varieties that have superior traits based on their agronomic character. The research activity was carried out in the Rantau Kapas Mudo Village, Batanghari Regency, Jambi Province from April to October 2016. The study used a single plot method. The local rice varieties used are genetic resources of swamp land rice planted in single plots measuring 10 m x 5 m, the distance between plots is 1 m with a spacing of 25 cm x 25 cm. The local varieties used were as many as 11 varieties, consisting of: Serendah Halus, Rimbun Daun, Karya, Serendah Bawang, Sereh Aek, Botol, Pontianak, Semut, Dawi, Ketan Itam and D.I. The characters observed consisted of plant height at harvest, number of productive tillers, age of harvest, number of grains per panicle, number of filled grains per panicle, number of empty grains per panicle, weight of 1,000 grains, seed shape and production. The results showed that there were differences between the local rice varieties of swamp land observed. The results showed that the highest production (3.32 tons / ha) was found in the Leafy variety, evidenced by the Dawi variety (2.86 t / ha). The results showed that there were two local rice varieties, Rimbun Daun and Dawi which had the potential to be developed and were expected to become the leading regional rice varieties in the swamp land.
