RESPON PERTUMBUHAN TANAMAN DAN HASIL BEBERAPA VARIETAS PADI SAWAH TADAH HUJAN (Oryza sativa L.) AKIBAT PENERAPAN TEKNOLOGI

Rainfed land with an area of 1.4 million ha is the second rice barn after irrigation land for Indonesia. Understanding rainfed land is land that has a bund but cannot be irrigated with a certain height and time continuously. Therefore the irrigation of rainfed land is largely determined by rainfall so that the risk of drought often occurs in the area during the dry season. So far, rice varieties for rainfed land that have resistant properties to blast disease are still very limited. On the other hand, it is very necessary to diversify the resistant varieties of blast disease to overcome the disease so that the resistance genes are not easily broken. Therefore we need a number of varieties with a wide diversity of resistance genes that are recommended for planting by farmers. The Agricultural Research and Development Agency has released drought-tolerant rainfed lowland rice varieties and several pests and diseases such as Inpari 10, inpari 38, inpari 40, inpari 42, inpari 43 and HHZ5-DT1-DT1 lines. The research method used was Factorial RGD with the treatment of PTT application and conventional technology interacted with rice varieties.The results showed that the application of PTT technology had a real / good influence compared to conventional technology on the growth and yield of rice plants. PTT can increase production by 5.9% and income by 12.6%. Inpari 42, Inpari 43 and HHZ5-DT1-DT1 varieties are relatively more stable than other varieties and Inpari 43 has a higher production compared to other varieties.

Thirteen traditional upland rice varieties (Kadidit Pilit, Red 64, Masipag 9, Masipag 15, Dinorado, Mindoro, Camuros, Masipag 22, Palawan, Suleg, Biday, Pilit , Pilit Talacdan) were evaluated in Randomized Complete Block Design (RCBD) in three replicates at the experimental area of Central Philippines State University (CPSU), Kabankalan City, Negros Occidental from November 2012 - April 2013. The parameters compared were their agronomic data on growth and yield, including grain characteristics. These data were processed using the one-way Analysis of Variance (ANOVA) with the Statistical Tool for Agricultural Research (STAR) (Version 2.0.1) while Duncan’s Multiple Range Test (DMRT) were used to compare significant treatment means at 1% level. The upland rice varieties showed significant variation in growth, yield showed distinct grain characteristics. Biday variety was the tallest, produced longer and wider leaves, and bore the longest panicle. Mindoro and Masipag 22 produced the most number of tillers. Pilit talacdan had the biggest culm, produced the heaviest panicle, with the highest number of filled grains per panicle. Pilit variety gave the heaviest weight of 1,000 grains. The grain features were also found to be distinct in each variety. The yield significantly varied among the upland rice varieties. Pilit and Pilit Talacdan gave the highest yield among the varieties grown at CPSU condition. The performing varieties would be used for upland rice improvement and breeding program and for further verification in the farmer’s field.

Blast Resistance Genes

Rice (Oryza sativa L.) is the staple food of the majority of Indians, and India is both the major producer and consumer of rice. Rice cultivation in India is confronted with diverse agro-climatic conditions, varying soil types, and several biotic and abiotic constraints. Among major fungal diseases of Rice in India, the blast caused by Magnaporthe oryzae is the most devastating disease, with the neck blast being the most destructive form. Most of the blast epidemic areas in India have been identified with a mixture of races blast fungus resulting in the resistance breakdown in a short period. At present, a more significant number of the rice varieties cultivated in India were bred by conventional breeding methods with blast resistance conferred by a single resistance gene. Therefore, the blast disease in India is predominantly addressed by the use of ecologically toxic fungicides. In line with the rest of the world, the Indian scientific community has proven its role by identifying several blast resistance genes and successfully pyramiding multiple blast resistance genes. Despite the wealth of information on resistance genes and the availability of biotechnology tools, not a great number of rice varieties in India harbor multiple resistance genes. In the recent past, a shift in the management of blast disease in India has been witnessed with a greater focus on basic research and modern breeding tools such as marker-assisted selection, marker-assisted backcross breeding, and gene pyramiding.

Planting Method

Field experiments were conducted at Punjab Agricultural University, Ludhiana (Punjab) to study the effect of different agronomic aspects of bed planting on growth and yield of rice during Kharif seasons of 2012 and 2013. The 30 days old seedlings of both rice varieties PR-118 (V1) and PR-116 (V2) were transplanted on 15th June (D1), 30th June (D2) and 15th July (D3). The two rice varieties were transplanted under bed planting (M1) and conventional planting (M2) methods respectively. The results showed that growth parameters like number of tillers per plant, dry weight per plant leaf area index (LAI) and plant height were significantly higher in bed planting than conventional method. In bed planting method, grain yield of rice (48.82q/h) was found to be more than the conventional method (35.74 q/h) during 2012.Varieties PR-118 yielded 47.61q/h more than PR-116 (39.97 q/h) in bed planting. Yield contributing characters like number of effective tillers, number of grains per plant and 1000-grain weight of rice were more in bed planting than conventional method. Harvest index and biological yield was also found to be more in bed planting method than conventional planting. Rice transplanted on 15th June yielded (50.15q/h) more than 30th June (41.45q/h) and 15th July (35.27q/h). Similar results were found in Kharif 2013. Interaction between dates of transplanting and varieties and between varieties and planting methods were found significant.

Marginal land along the coast should be utilized to increase the national rice production. In addition, the use of saline resistant varieties, it is necessary to determine the best seedling age for saline soil. This study aimed to evaluate the growth and yield responses of two rice varieties transplanted at different seedling age on saline soil. The experiment was arranged in a factorial Randomized Completely Block Design (RCBD) with three replications, conducted at saline coastal area of Baros, Yogyakarta, starting from January to June 2017. The first factor was rice varieties, consisting of Dendang and IR-64. Meanwhile, the second factor was the seedling age, consisting of 2 and 4 weeks after sowing (WAS) seedlings. The results showed that the growth and yield of two rice varieties (Dendang and IR-64) showed significant difference, and Dendang showed a better performance than IR-64. The higher yield of Dendang compared to IR-64 was supported by higher plant growth (shoot dry weight) and yield components (number of seeds per panicle, seed weight per plot, and productivity). The 2 and 4 WAS seedlings did not give significantly different effects on nearly all growth variables. However, 2 WAS Dendang rice seedlings had higher shoot dry weight. Meanwhile, IR-64 had higher leaf greenness in 4 WAS seedlings compared to that in 2 WAS seedlings.

Tidal swamp lands are marginal lands with considerable potentials for rice farming. The key solution to overcome swampy lands constraints are nutrient and water managements as well as the use of adaptive rice varieties. Inpara (inbred swampy land rices) varieties have been released by the Indonesian Agency for Agricultural Research and Development (IAARD) which are adaptive to swampy land conditions. The purpose of this research was to evaluate the adaptability of Inpara varieties in tidal swamp lands with type B overflow. The field experiment was carried out in Karang Bunga village, Barito Kuala District, South Kalimantan Province, in the dry season from April to August 2016. The research was arranged in randomized complete block design, with 3 replicates. The varieties tested, i.e., Inpara 1, 2, 3, 4, 5, 6, 7, 8, 9, and check varieties Margasari, Ciherang, and Mekongga. The results showed that the adaptability varied among varieties tested. Inpara 3, 4, 6, 8, and 9 had high yield and good adaptation on tidal swamp land yielded 3.475-4.299 ton ha-1. These varieties produced between 38.5 to 71.3% higher than Margasari and 51.4 to 87.2% higher than Mekongga. Inpara 3, 4, 6, 8, and 9 could be used as a main varieties in the tidal swamp lands.<br /><br />Keywords: rice, swampy land, variety

Nilaparvata Lugens Stål

The brown planthopper (BPH: Nilaparvata lugens Stål.) is a major pest of rice, Oryza sativa, in Asia. Host plant resistance has tremendous potential to reduce the damage caused to rice by the planthopper. However, the effectiveness of resistance genes varies spatially and temporally according to BPH virulence. Understanding patterns in BPH virulence against resistance genes is necessary to efficiently and sustainably deploy resistant rice varieties. To survey BPH virulence patterns, seven near-isogenic lines (NILs), each with a single BPH resistance gene (BPH2-NIL, BPH3-NIL, BPH17-NIL, BPH20-NIL, BPH21-NIL, BPH32-NIL and BPH17-ptb-NIL) and fifteen pyramided lines (PYLs) carrying multiple resistance genes were developed with the genetic background of the japonica rice variety, Taichung 65 (T65), and assessed for resistance levels against two BPH populations (Hadano-66 and Koshi-2013 collected in Japan in 1966 and 2013, respectively). Many of the NILs and PYLs were resistant against the Hadano-66 population but were less effective against the Koshi-2013 population. Among PYLs, BPH20+BPH32-PYL and BPH2+BPH3+BPH17-PYL granted relatively high BPH resistance against Koshi-2013. The NILs and PYLs developed in this research will be useful to monitor BPH virulence prior to deploying resistant rice varieties and improve rice’s resistance to BPH in the context of regionally increasing levels of virulence.

The Impact

Jumla is one of the 75 districts in the midwestern hills of Nepal. Rice (Oryza sativa L) cultivation in Jumla ranges from 2,400 to 3,050 m altitude, which is the highest elevation in the world. The highest elevation at 3,050 m is Chhumjul of Jumla, a record altitude, where rice is cultivated in Nepal. Jumli Marshi, a Japonica variety of indigenous rice, having cold tolerant gene, is probably cultivated since 1,300 years ago in Jumla in the bank of the Tila river. Improved rice varieties were tested in the Jumla valley by the Nepal Agricultural Research Council (NARC). In 2002, two improved rice varieties Chandannath-1 and Chandannath-3 were released for temperate region of Jumla and Karnali zone. Productivity of rice in Jumla is 1.7 mt/ha almost 40% lower than that of national average of 2.97 t/ha. Low productivity of rice is mainly due to the constraints of many biotic, abiotic and socio-economic factors. Food security in the food deficit region of the Karnali zone could be sustained by increasing rice productivity in the Jumla region where perennial irrigation is available round the year. Whole of the Jumla region is unique place with respect to rice cultivation in the highest altitude of the world. The practice of rice cultivation in Jumla could be a remarkable activity for boosting agro-tourism in the agrarian country like Nepal. Rice cultivation in Jumla is quite unique from the rice cultivation even in the same range of temperate region. Such a typical organic rice production system in the highest elevation of the world needs immediate attention of all institutions and authorities concerned to conserve it for the future generation as well. Jumla, the temperate region, is also affected by the impact of global warming thereby receding water level in the Tila river and its tributaries flowing in the Jumla valleys during rice growing season (March - October). Attempts have been made to document ethno-culture, socio-economic and cultural practices of rice cultivation in the highest elevation in the world.

Beneficial Elements

Background: The beneficial elements availability such as silicon was determined rice growth and yield. Rice requires a different dose of silicon during the growing period. Experiment was aimed to investigate the effect of silicate levels, rice varieties and the interaction of the two on the growth and yields of two local Indonesian varieties of rice. Methods: A completely randomized design of factorial pattern with 4 replications was used in the experiment. Treatments consisted of No added SiO2 (Si-0); added 100 and 200 kg SiO2 ha-1, respectively for Si-100 and Si-200 and two local rice varieties, Pandan wangi (P1) and Mentik susu (P2). Result: The treatment had no significant effect on growth and yield of rice. Addition of 100 and 200 kg SiO2 ha-1 to P1 and P2 did not show a significant difference on the growth and yield of rice compared to control (P0). Plant height and root dry weight at P1 was lower than P2, but the 1,000-grain weight was showed, vice versa. Silicon addition up to 200 kg SiO2 ha-1 may not be recommended to be applied in rice cultivation, especially Pandan wangi and Mentik susu varieties. Improving the two varieties, further research is needed by increasing the silicon doses.
