Abstract

Halimi et al. 2012. In-situ Evaluation of Growth Rate and Yield Components of  Several Non-tidal Swamp Rice Accessions in South Sumatera. JLSO 1(2):107-115Rapid increase of agricultural land conversion has led to the intensified utilization of  non-tidal swamp. The objective of this research was to identify growth rate and yield components of several rice accessions of non-tidal lowland swamp of South Sumatera. This research incorporated the cultivation of nine rice accessions  in  non-tidal swamp area. Research plots were prepared  by local farmers to include  27 plots of 280 cm x 80 cm following the Complete  Randomized Block Design.  Research indicated that rice accessions might be classified into 3 groups of Low Growth Rate (LGRA), Intermediate Growth Rate (IGRA), and High Growth Rate (HGRA) accessions.  Each group has different growth rate according to the field water level during flooding season of < 5 cm, 5 to 6 cm, and >6 cm  per week, respectively. The LGRA group consisted of  Petek (A5) and Senia (A6), the IGRA group consisted of Bone (A1), Pelita Rampak (A2), and Sawo Rimbo (A7) and the HGRA group consisted of Kuning (A3), Siam (A4), Sawah Beling (A8) and Putih Olak (A9). Some yield components tended to decrease as the growth rate increased, and some varied depending on the accessions. For effective and efficient cultivation, farmers should apparently consider growth rate and yield potential to decide which rice accessions to grow.

Abstract

The Centella asiatica is an important herbal plant in Indonesia. The research was done to describe severalagronomic traits that related to yield of the plants grown at regions with different altitudes. The research wascarried out at three different regions of highland, midland, and lowerland, each at >500m, 250-500m, and < 250mabove sea level. The research location was Pagar Alam, Musi Rawas, and Ogan Ilir, respectively. Research indicatedthat the agronomic traits of the plants grown at highland, midland, and lowerland, regions were about the same forgeneral appearance of leaf shape and flower color. The leaf size, number and length of stolone, number of rossets,length of rhizomes, and number of flower were varied depending on the region. The plants grown at highland andmidland region tend to have larger leaf size, shorter petiole and stolone, more number of rossets and stolone,longer rhizomes, and more number of flowers per plant, compared to the plants of lowerland region. This could beindication that Centella asiatica plants grown on midland, and highland were more productive than plants oflowerland region.
