<p>ABSTRACT<br /><br />The morphophysiology of ratoon is different from the main plant of rice and was influenced by location and cultivation.This research was intended to evaluate morphophysiology characters of rice ratoon planted by direct seeding system in tidal swamp at various stubble cutting height. The experiment was conducted in November 2013-April 2014 at tidal swamp overflow type B in Telang Sari Village, District of Tanjung Lago, Banyuasin, South Sumatra Province. The experiment used randomized block design with 5 replications. Treatment was stubble cutting height 10, 20, 30, 40 and 50 cm above the soil surface. Rice was planted at 4 m x 5 m plot, the distance between plot 1 m. Data were analyzed by test of variance and 5% HSD test. Morphophysiological characters of rice ratoon were influenced by stubble cutting height. Cutting height of 20-40 cm above soil surface increased the ratoon number of tillers per hill, leaf area per hill, dry weight per hill, percentage of empty grains per panicle, grain weight per hill and percentage ratoon/main crop production per hill. The higher stubble cutting, the lower the number of leaves per tiller, leaf area per tiller, carbohydrate content, and number of grains per panicle of ratoon, however it accelerated age of flowering and harvesting. <br /><br />Keywords: direct seeding system, ratoon system, rice growth and production, stubble cutting height<br /><br /></p>

Dioscorea is potentially used as staple food to support food security. The research was aimed to determine the effect of stake length and time of  stem twining  on  the growth of Dioscorea sansibarensis Pax. The experiment was conducted  in  Purwodadi Botanic Garden from December 2014 until May 2015 using split plot randomized block design consisted of two factors, i.e. the stake length and time of stem twining. The stake length was the main plot consisted of 150 cm, 100 cm and 50 cm above soil surface and without stake (control). The time of stem twining as subplots, i.e. stem twined early, twined at the time of 4 leaves stage, and twined at 8 leaves stage. Each combination of the treatments was replicated three times. The results showed that there was significant effect on the stake length  and the time of stem twining treatments on the plant growth and yield. The stake  length of 150 cm treatment produced the highest fresh tuber and total plant dry weight, i.e., 257.24 g and 132.77 g per plant, respectively. On the contrary, the plant without stake produced the lowest fresh tuber and  total dry weight of plant, i.e., 112.10 g and 48.65 g per plant, respectively.<br /><br />Keywords: biomass,leaf area, photosyntesis, tuber weight
