ABSTRACT Two field experiments were carried out in saline soil receiving fertilizers NPK @ 130-75-75 kg ha-1, respectively, to see the effect of seedling age and number of seedling hill-1 on rice growth and yield. Rice seedlings of 25-, 35- and 55-day-old were transplanted in puddled field. Results revealed that seedlings of 25- to 35-day-old produced significantly higher number of tillers and productive tillers hill-1, paddy and straw yields compared with 55-day-old seedlings. In the second experiment, transplanting of two and three seedlings hill-1 of 35-day-old gave more promising results compared with one and four seedlings. Two seedlings hill-1 caused maximum increase in plant height, straw and paddy yield while more number of tillers and productive tillers were recorded with three seedlings hill-1.

    ABSTRACT: Innovations in water saving technologies are the foremost needs in today's rice production as water has become the most limiting resource in agriculture. This study was conducted for evaluating conventional, system of rice intensification (SRI) and modified water management methods in direct-seeded and transplanted rice in order to determine the best water management practice that increases grain yield and water productivity. A 2x3 factorial experiment, where two methods of establishment (viz. direct seeding and transplanting with 8 day old seedlings (TPR)) and three water management methods (viz. conventional water management (CWM), two-week irrigation followed by two-week non-irrigation (2W-2N) and one-week irrigation followed by three week non-irrigation (1W- 3N)), was conducted in a randomized complete block design with four replicates. Soil moisture contents at 0-15 cm and 15-30 cm soil layers reached near the lower levels of the readily available water (RAW) during non-irrigation periods in 2W-2N and 1W-3N, but never depleted below RAW level. There were interactions between establishment method and water management for leaf area index (LAI), root parameters, yield and yield components, harvest index and water productivity. Conventional water management was inferior to 2W-2N and 1W-3N, and direct seeding and transplanting had no difference. Overall results showed that there are greater benefits of water saving, yield and net income with 1W-3N water management combined with direct seeding over SRI and CWM and transplanting for 120-day old Suphan Buri 1 hybrid.

    ABSTRACT: Salinity tolerance in rice varies with the state of growth, with the seedling and reproductive stages being the most sensitive. However, association between tolerances at the two stages is poor, suggesting that they are regulated by different processes and genes. Tolerance at the reproductive stage is the most crucial as it determines grain yield. An F2 mapping population was developed from two rice genotypes contrasting in tolerance: Cheriviruppu and Pusa Basmati 1 (PB1). Cheriviruppu is highly tolerant at the reproductive stage, while PB1 is highly sensitive at both seedling and reproductive stages. One hundred and thirty-one microsatellite markers polymorphic between the parents were used to construct a linkage map of 1458.5 cM (Kosambi), with a mean intermarker distance of 11.1 cM. Sixteen QTLs with LOD values ranging from 3.2 to 22.3 were identified on chromosomes 1, 7, 8 and 10, explaining 4–47 % of the phenotypic variation. The maximum number of QTL clusters for different component traits was colocalized on the long arm of chromosome 1 and chromosome 7. We identified several significant epistatic interactions, including three inter-QTL interactions, using MapManager. The results suggest that pollen fertility, Na+ concentration and Na/K ratio in the flag leaf are the most important mechanisms controlling salt tolerance at the reproductive stage in rice. The study reports the construction of a genetic map for reproductive-stage salt tolerance in rice and demonstrates its utility for molecular mapping of QTLs controlling salinity tolerance-related traits, which will be useful in marker-assisted selection in the future.

    ABSTRACT: Seedling vigor is the basic component of the transplanted rice, which depends on its growing environment and proper age. Thus the influence of nursery management and seedling age was evaluated after transplanting 10, 20, 30, and 40-days older seedlings raised by using seed rate (high and low) and nitrogen (N) (with and without) in rice growing season 2008 and 2009. Study revealed that 10-days older nursery seedlings, irrespective to nursery-bed treatments, showed accelerated growth start after transplanting in main field while at later stages significant interaction was observed. Transplanting of 20-days older fertilized seedlings grown at low seeding density at nursery-bed resulted in similar growth performance as in younger. Maximum net-benefit (45111, 44402 Rs. ha−1) was recorded with transplanting 10-days older nursery seedlings while the fertilized seedlings grown at lower seeding density recorded highest net-benefit (37908, 36780 Rs. ha−1) in both the years.
