Respon Pertumbuhan Dan Produksi Beberapa Varietas Padi Gogo (Oriza Sativa L.) Dengan Ketebalan Tanah Mineral Pada Lahan Gambut

Abstract

A large area of feat soil as available across Aceh Singkil province of Aceh. The possibility of the area for upland rice farming is necessary tube evaluated. This study aim to evaluate the growth and yield of upland rice varieties on peat soil with different thickness of soil. The research used randomized block design with 2 (two) factors. The first factor was rice varieties (V) were consist of (1) Local variety (Siliam varieties), (2) Situ Bagendit varieties, (3) Situ Patenggang varieties and (4) Batutegi varieties. Where as the second factor thickness of mineral soil applied on peat wich consist of 5 cm, 10 cm, 15 cm, 20 cm and no mineral soil as a control. The results indicated that varieties of upland rice showed significant effect on the growth and production variable such as plant height 4, 6, 8 and 10 weeks after planting, where Situ Bagendit variety was the highest among the varieties. Similarly number of tillers 4, 6, 8 and 10 weeks after planting, the highest number of tillers was found on Situ Bagendit variety, while for highest number of grain per panicle was in Batutegi varieties. The thickness of mineral soil applicated on peat soil indicated significant effect on the growth and production variables such as plant height 4 weeks after planting. The highest yield of upland rice was fond on Situ Bagendit variety followed by Batutegi variety, Situ Patenggang variety and local variety (Siliam variety)
