Abstract

ABSTRACTThe 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. Keywords: direct seeding system, ratoon system, rice growth and production, stubble cutting height

Abstract

The use of curly chili as a food ingredient continues to increase. It is necessary to increase production through the use of superior varieties by utilizing tidal land that is widely available in South Sumatra. This research aimed to obtain superior varieties of curly chili IPB with the potential to be developed for tidal land of South Sumatra. The experiment was conducted from July 2020 to January 2021 on potential acidic sulfate soil of tidal land overflow type C, using a randomized complete block design with three replications. Tested genotypes were six IPB’s curly chilies, namely F10-120005-141-16-35-3-2B, F10-120005-141-16-35-1-4-3B, F10-120005-141-16-35-7-1-3B, F10-120005-241-2-9-4-4-1-1B, F10-120005-120-7-1-7-8-1-2B, F11-0005-9-6, and four check genotypes, namely SSP, Laris, Caman, F1-PM999. Analysis of variance followed by the HSD test was conducted. The relationship between variables was analyzed using Pearson correlation. Test genotype F10-120005-120-7-1-7-8-1-2B had tall stems and produced higher fruit weight than the check genotype, as it has the highest flesh thickness, longer fruit, and the largest fruit diameter. IPB genotypes F10-120005-141-16-35-1-4-3B, F10-120005-141-16-35-7-1-3B, F10-120005-241-2-9-4-4-1-1B, F10-120005-120-7-1-7-8-1-2B are potential to be developed as superior curly chili varieties in potential acidic sulfate soil on tidal land of South Sumatra, with productivity ranging from 11.38 to 12.92 ton ha-1. Curly chili genotype had different growth abilities in tidal land depending on their ability to adapt to the growing environment according to their genetic characteristics. Keywords: adaptive genotype, check genotype, suboptimal land, test genotype
