Abstract Poor germination and subsequent low grain yield of dry seeded upland rice in the existing anaerobic and short niche between lowland rice and dry season crops in the inland valley necessitate the screening of 19 rice varieties. The identification of vigorous growth and short duration upland rice variety in anaerobic condition would optimize this niche. The potted experiment was carried out in the screen house of the Department of Crop Science and Horticulture, Federal University Oye-Ekiti, Ikole campus in 2015 to screen and evaluate the performance of upland rice varieties in inundated soils with a view to selecting the suitable variety or varieties that will fit into the existing niche in the inland valley. The experiment was laid in a complete randomization design and replicated three times. The number of leaves, biomass and grain weight plant−1 of the varieties were significantly (P ≤ 0.05 %) different. The number of tillers observed in WAB 56-104, NERICA 4, NERICA 6, NERICA 3, NERICA 5, NERICA 10, NERICA 9, ARICA 4 NERICA 1, FARO 63, FARO 65 and NERICA 8 varieties were significantly (P < 0.05) lower than those of Igbemo varieties. The numbers of days to 50 % flowering of NERICA 1, NERICA 2, NERICA 10, NERICA 5, NERICA 9, NERICA 3, NERICA 7, NERICA 8, ARICA 4 and WAB 56-104 varieties were the lowest. Although Igbemo brown, Igbemo white varieties had the highest grain yields per plant, their maturity period exceeded the short period. Thus, NERICA 2 and NERICA 5 varieties which had lower number of days to flowering could be considered as candidate varieties that can be optimized in the niche in question.

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.

Rice blast, caused by the fungus, Magnaporthe grisea (M. grisea), lead to the decrease of rice yields widely and destructively, threatening global food security. Although many resistant genes had been isolated and identified in various rice varieties, it is still not enough to clearly understand the mechanism of race-specific resistant ability in rice, especially on the protein level. In this research, proteomic methods were employed to analyze the differentially expressed proteins (DEPs) in susceptible rice variety CO39 and its two near isogenic lines (NILs), CN-4a and CN-4b, in response to the infection of two isolates with different pathogenicity, GUY11 and 81278ZB15. A total of 50 DEPs with more than 1.5-fold reproducible change were identified. At 24 and 48 hpi of GUY11, 32 and 16 proteins in CN-4b were up-regulated, among which 16 and five were paralleled with the expression of their corresponding RNAs. Moreover, 13 of 50 DEPs were reported to be induced by M. grisea in previous publications. Considering the phenotypes of the three tested rice varieties, we found that 21 and 23 up-regulated proteins were responsible for the rice resistant ability to the two different blast isolates, 81278ZB15 and GUY11, respectively. Two distinct branches corresponding to GUY11 and 81278ZB15 were observed in the expression and function of the module cluster of DEPs, illuminating that the DEPs could be responsible for race-specific resistant ability in rice. In other words, DEPs in rice are involved in different patterns and functional modules’ response to different pathogenic race infection, inducing race-specific resistant ability in rice.

Crop Performance

The objective of Organic farming is to achieve crop sustainability through restoration of soil dynamics, improvement of plant health through improvement of the soil - plant interactions, nourishment of the environmental resistance and reducing pest interferences. Lack of scientific guidelines and comprehensive organic package of practice (POP) has rendered the objective unachievable. The present study was initiated at Howrah Krishi Vigyan Kendra in 2015 and 2016 to evaluate the potential of Inhana Rational Farming (IRF) Technology, an organic POP, towards increasing crop productivity and restoration of soil quality under rice cultivation under different farming model viz. organic, integrated, non-pesticidal crop management as well as KVK.s recommendation with reduced fertilizer dosage. Treatments with organic plant management practices (IRF technology) showed 5% higher crop productivity (4774 kg/ha) in comparison to conventional farmers’ practice (4537 kg/ha) for Swarna sub-1 rice variety. Where as in case of scented rice varieties like Gobindobhog, the organic practice showed highest crop performance (3194 kg/ha) among all the treatments, and achieved 17% higher yield than that obtained under conventional farmers’ practice (2726 kg/ha).  Also the non-pesticidal crop management, a new concept of synthetic pesticide free crop cultivation under IRF Technology showed higher crop performance (4991 kg/ha and 2978 kg/ha in Swarna sub-1 and Gobindobhog rice varieties respectively) than conventional farmers practice. Organic plant management under IRF aimed at activation of plant physiology was found to have a positive impact towards agronomic development and yield performance as compared to conventional practice. Assessment of soil quality parameters indicated increasing trend of soil quality especially in terms of soil biological parameters for plots receiving Novcom compost.

Photosensitive rice varieties have higher advantages in delayed planting. The present study was undertaken to figure out the degrees of delayed planting and evaluate the performance of six modern Aman rice varieties (BR11, BR22, BR23, BRRI dhan46, BRRI dhan54) against three sets of delayed planting. Each rice variety showed considerable variations for plant height, days to panicle initiation, flowering and maturity. BR22, BR23, and BRRI dhan54 showed a drastic reduction in days to panicle initiation and varied from 65 to 58 days, 69 to 60 days, and 62 to 55 days respectively, while it varied from 76 to 80 days for the control variety BR11. Similarly, days to flowering of BR22 and BRRI dhan54 showed a gradual decrease following different planting time and varied from 92 to 86 days, and 83 to 77 days respectively, while it varied from 109 to 107 days for the control variety BR11. For the above traits, BRRI dhan44 and BRRI dhan46 showed a moderate reduction depending on the three sets of planting time. Grain yield of BR22, BR23 reduced at the third set with a value ranging from 5.8 to 5.0 t/ha, 6.1 to 5.1 t/ha respectively, while BRRI dhan54 showed consistency in grain yield with a range from 5.3 to 5.2 t/ha. In contrast, grain yield of remaining rice varieties ranged between 5.7 to 4.5 t/ha for BRRI dhan46, 6.2 to 3.9 t/ha for BRRI dhan46 while severe reduction for the control variety BR11 with a range from 4.4 to 2.0 t/ha was observed. In conclusion, BRRI dhan54 was found more suitable rice variety in delayed planting compared with other photosensitive rice varieties. In future, BRRI dhan54 could be used as benchmark rice variety in a special rice breeding programme designed for delayed planting. Bangladesh Rice j. 2019, 23(1): 65-72

Abstract BackgroundGlobal warming, climate change, environmental stress and population increase have threatened food security and increased food production demand. Increasing Rice productions could be a better solution to solve or at least decrease the severity of the global food crisis. The modern rice cultivation techniques have been insufficient for sustainable rice production. So, Qiangdi 863 nano synergid is hypothesized to enhance the early growth of rice, rice physiology, grain yield, and grain quality. ResultsThe present study was carried out to determine the role of Qiangdi 863 nano synergid on the growth and yield of one Chinese rice variety Zhongzao 39 and four Pakistani rice varieties KSK 133, KS 282, Super basmati, and PK 1121 aromatic. Field experiments were conducted during the years 2017, 2018, and 2019. Appling nano-treated water enhanced the germination rate along with radicle and plumule lengths and improved the photosynthesis rate, SPAD value in rice leaves for all five varieties. The results showed that nano-treated water improved the anti-oxidant Catalase activity (CAT), Superoxide Dismutase (SOD) Peroxide (POD) production, declined Malondialdehyde (MDA content), enhanced endogenous Salicylic acid (SA), Jasmonates (JA) Brassinosteroids (BR) hormonal concentration and yield parameters of rice in 2017, 18 and 19 years of data. ConclusionThese findings indicate that nano synergids can be effectively used for rice cultivation in different environmental conditions (China and Pakistan). This is the first reported application of Qiangdi 863 nano synergid in Pakistani rice varieties with effective outcomes highlighting significant results in KSK 133.
