Abstract

Subculture is one of stages to produce plant through tissue culture. Basically, subculture is to cut, cleave, and replant explant that grows for increasing number of plants. The purpose of this research is to sterilization a part of pant from field which will be used as explant and to make sub-culture on a part of plant to produce in vitro. Generally, the explant sterilization of orchid fruit and Red Betel Vine produces under satisfaction because of up to 90% of explant experiences contamination by fungus, bactery and browing. Sub-culture krisan on callus medya shows that a small number of culture successed to form callus, while other ones experiences contamination. On krisan sub-culture in bud medya is obtained a good result and differ significantly with others under a high level of contamination. All of those are likely caused by unskill in creating a sterile condition in the explant sterilization practices as well as at time in making sub-culture.

Abstract

Parallel technique of legowo was disseminated to SLPTT locations in Riau Province for 9 regencies, i.e., Indragiri Hilir (25 LL), Indragiri Hulu (60 LL), Rokan Hulu (182 LL), Pelalawan (50 LL), Rokan Hilir (25 LL), Kuantan singingi (63 LL), Kampar (140 LL) and Siak (33 LL). However, the research related to affectivity of parallel technique of legowo for supporting the increase of rice production in Riau Province has not been conducted. Therefore, it is needed a research on adoption of parallel technique of legowo. The purpose of this research was to increase knowledge, attitude, and skill of farmers in activity for optimally using inputs by parallel technique of legowo planting. The results showed that production cost per growing season of rice farming for cooperator farmer was higher than non-cooperator, namely Rp. 9,247,711.63/ha and Rp. 8,815,445.83/ha, respectively. The high cost incurred by cooperator farmer was due to the high use of fertilizer.

Abstract

Testing germination in principle is to test a number of seeds and determine the percentage of seeds that can grow or be able to germinate normally at the specified time period. This test aimed to learn how to test a variety of seeds and germination of seeds of a particular lot by using a paper substrate, assessing different types of seeds that germinated species and classify them, determine the viability of a seed lot with benchmark germination. Tests on rice seed germination showed that seeds still qualify for graduation certification under the provisions established by the Directorate General of Food Crops for germination percentage above 80%. In addition, the percentage growth rate (KCT) is also quite high which indicates that the seed is still vigor. Benih corn and soybean seed were tested did not meet the graduation requirement of certification of seeds but the percentage growth rate (KCT) each classified as still having medium and high vigor. Germination in spinach showed that seeds still qualify for graduation certification. Evaluation of two maize seed lots showed normal germination percentage significantly. Quality tested physiological soybean seed has declined, by looking at the percentage of normal seedling is quite low and the percentage of dead seeds are quite high.

Abstract

Integrated Plant Management Approach as a national program must be applied on the rice production centers. One of rice production center in Riau Province is Bunga Raya District, Siak Regency. In 2010, the cultivated area of rice in the district was 8,546 ha with total production of about 21,083 MT/ha. The aim of this research was to know the adoption level of integrated plant management of paddy filed by farmers. The research was conducted in Bungaraya Village, Bungaraya District, Siak Regency from January to December 2011. The measurement of adoption level and dissimination impct of integrated plant management for paddy included farmer identity, technology componen of integrated plant management for paddy, farmer response level, and feedback. The results show that the level of farmer adoption of technology componen for integrated plant management was reletively high, ranging from 82 – 100%. The integrated plant management approach increased rice productivity from 3.4 MT/ha to 5 – 6 MT/ha. Therefore, Bunga Raya as rice barn of Siak Regency which is begun from increasing planted area and cropping index of rice from Regency government.
