In present study, 26 microbes consisted of 11 fungal isolates and 16 bacterial isolates were screened against blast disease pathogen (Pyricularia oryzae). All isolates were screened in vitro via dual culture bioassay. All fungal isolates collected were isolated from aerobic rice soils and the endophyic bacteria were isolated from the stem of healthy rice plants. Five isolates have been identified to be potential biocontrol agents as they recorded high PIRG (percentage inhibition of radial growth) values of more than 80%. Two isolates were identified as Trichoderma (F15 and F16) while the rest of them were bacteria isolates (I5, I6 and I16). 16S rDNA sequence analysis results showed that all three bacterial isolates were 100% similar to Paenibacillus polymyxa (Gene Bank assession number: GU332610.1). © 2014 Penerbit UTM Press.

Pomacea spp. or apple snails are one of the main rice pests in Malaysia. It is unfortunate that farmers prefer to use chemical molluscicides especially the illegal mollusicicides from other countries to control this pest. The use of chemicals brings negative effect to farmer's health and environment. One of the suggested measures to avoid the excessive use of chemical molluscicides is by physical control through handpicking. However, manual handpicking is backbreaking and not very effective. The use of attractant baits can ease the hard work of manual handpicking or enabling spot spraying of molluscicides which minimizes the overuse of application. The effectiveness of several materials as apple snail attractant baits was studied on screen house scale and field scale. Jackfruit and papayas are highly recommended to be used as attractant baits as well as cassava leaves and water spinach. Most of the snails were found attached to the materials either to feed or for shelter. All these type of attractant baits can be used to gather and collect apple snails in rice fields especially before the broadcasting stage of the rice seeds. The use of attractant baits also is seen as an important component of integrated management of the apple snail. © 2014 Penerbit UTM Press. All rights reserved.

The purpose of this study was to determine the physicochemical properties, cooking characteristics and nutritional content of MR 283 and MR 284 rice varieties. These samples were evaluated in form of milled rice. The physicochemical properties determined were gelatinization temperature and gel consistency. The samples analysed had high gelatinization temperature. Intermediate gel was detected in the rice samples. Variations in cooking time, elongation ratio, volume of expansion, water uptake ratio and solid loss were observed. The rice had elongation ratio of less than 2 which indicated that rice samples did not elongate during cooking. MR 283 milled rice contained 7.43% protein and 0.77% fat contents while MR 284 had 8.6 and 0.74% of protein and fat contents respectively. Analysis of mineral and vitamin contents indicates that the rice samples had different values for nutritional contents. © 2014 Penerbit UTM Press. All rights reserved.

The study was conducted at screening house to determine the resistance levels of several potential varieties against colonies of brown planthopper, Nilaparvata lugens collected from nine different localities in Peninsular Malaysia. Assessment using SSST method found two varieties, MR286 and MRQ89 have shown high level of resistance to all of the colonies tested, followed by MR284, which was moderate resistant to most of the colonies except colony originate from Seberang Perak of which is moderately susceptible. Rice varieties MR283 and MR278 were moderately resistant to most colonies but susceptible after been tested to colony derived from Kodiang, Kedah. Resistance levels of control varieties MR253, MR263 and MR269 varied between moderate resistant to susceptible depended on colonies used in the testing. Field study found that moderate resistant varieties do not show immunity. Brown planthoppers can still be found in varieties and they play a role in keeping predator populations in the field. © 2014 Penerbit UTM Press. All rights reserved.

The diversity of arthropod consists of pests and predators in rice fields were contribute to the biological control of crop pests at different stages of growth. The rice fields in Batang Lupar, Sarawak has diverse ecological conditions as well as presence of arthropod too. The study in MARDI research plot Batang Lupar in Sri Aman, Sarawak had been done on traditional rice varieties, Bubuk, Bali and Mamut by using sweeping net. The entire specimens were sorted out and classified into the smallest possible taxa. Statistical analysis were analysed by using Shanon-wiener Diversity Index, Evenness Shannon Index and Margalef Richness Index. A total of 272 individual arthropods had been collected and it consists of 7 order, 18 families and 23 species. Among of that 3 species are spiders, 9 species are insect pests and 11 species are insect predators. Analysis data for the diversity of arthropod has shown that there were no significantly different between three varieties, Bubuk, Bali and Mamut (P > 0.05). Besides that, diversity of the arthropod in Bali is higher than Bubuk and Mamut. © 2014 Penerbit UTM Press. All rights reserved.

Red rice is classified as specialty rice due to its coloured grain. Red colour that surrounded the outer layer of pericarp showed the existence of anthocyanin in red rice grain. However, heavy metal like arsenic in red rice plant become major concern in human health especially so in babies. This is because red rice normally used as a key raw material in the manufacture of infant cereals. In order to overcome this problem, study on effects of water regime on arsenic concentration in local red rice, MRM 16 was conducted during main season 2007/2008 and off season 2008. The water regimes tested were fully flooded, semi-aerobic and aerobic soil conditions. Result showed that arsenic concentration in the soil and grain was markedly highest when MRM 16 was cultivated under fully flooded in both seasons. However, concentration of arsenic in the soil and grain samples was the lower when the red rice was cultivated under semi-aerobic and aerobic soil conditions. Arsenic concentration in the soil and grain samples showed positive relationship. However, analysis of grain yield showed that the yield performance of MRM 16 was better when the soil was fully flooded or maintained semi-aerobically. © 2014 Penerbit UTM Press.

Effect of different rates of N and K on yield and yield components for MR 269 and MR 278 was conducted in Sungai Limau, Yan, Kedah during off season 2012 and main season 2012/2013. The treatment consisted of factorial combination of two rice varieties (MR269 and MR278) with 3 different rates of N and K2O (0, 100, 200 kg/ha) laid out in randomized complete block design and replicated three times. In off-season of 2012, MR 269 and MR 278 responded positively to yield performance (t/ha) when N rate was 100 kg/ha and 200 kg/ha respectively in line with the rate of K2O from 0 kg/ha to 200 kg/ha. However respond MR 269 is better than MR 278. During the main season 2012/2013, MR 269 and MR 278 showed a positive response when N rate was 200 kg/ha and 100 kg/ha but differ in the rate of K. However the main season MR 269 shows a lower yield performance compared to MR 278. These findings suggest that, MR 269 can achieve optimum yield potential at the rate of 100 kg N/ha but different of K at the rate of 200 kg K2O/ha and 100 kg K2O/ha respectively in the off-season and main season. While the MR 278, N and K2O at the rate of 200 kg/ha showed optimum yield in the off-season. Meanwhile, at the rate of 100 kg N/ha and 200kg K2O/ha in the main season can provide optimum yield. © 2014 Penerbit UTM Press. All rights reserved.

An experiment to study influence of nitrogen (N) and potassium (K) on new rice varieties MR 269 and MR 284 has been carried out in Parit 12 Sungai Nibong, Sekinchan, 45400, Sabak Bernam, Selangor from February 2012 to January 2013. Compatibility tests need to be carried out on current fertilizer recommendation towards these new rice varieties. There are three rates used in this experiment which are 0, 100 and 200 kg/ha for both N and K fertilizer. The experimental design used in this experiment is Randomized Complete Block Design (RCBD) with 3 replications. A set of 54 small plots were erected with 4 m x 4 m in size. Manual Teknologi Penanaman Padi Lestari is used as crop management guideline for this experiment. Results indicated no significant interaction between N and K on yield of the newly tested rice varieties. The rice yield was significantly affected by N but not by K. Results suggest that there is significant interaction between cropping season and N towards rice yield. Analysis showed that fertilizer application of N up to 200 kg/ha contributed to higher yield in first season (Off-season). However, yield increment in season 2 (main season) only took place up until N fertilizer application at 100 kg/ha and began to drop when subsequent additional of 200 kg/ha. This study indicated that number of panicle and number of seed per panicle had positive influence to the rice yield. © 2014 Penerbit UTM Press. All rights reserved.
