“…The variation in the duration of the seedling stage was reflecting the temperature variation during that period. Vange and Obi (2006) observed the impact of early and late seeding dates on grain yield and several agronomic traits. These results suggested that the planting date had a big impact on the duration of seedling stage under variation of temperature.…”

“…The prerequisites that allow the crop to complete its life phase in a timely and fruitful manner are proper seeding time and technique. (Vange and Obi, 2006). According to Khalifa (2009), an early sowing date is ideal for obtaining important characteristics like the maximum number of tillers, the highest number of panicles per square meter, the highest number of grains in each panicle, and finally grain yield.…”

Identification of growth stages of rice is important for proper crop management and yield estimation. Appropriate planting time is a prerequisite for a decent harvest. The study aimed to determine the growth stages of different rice varieties and how they are affected by the sowing time. We evaluated four selected boro season rice varieties (BRRI dhan81, BRRI dhan86, BRRI dhan88, and BRRI dhan89) under five sowing times for growth stage study and yield following a completely randomized block design (RCBD) with three replications. Each variety showed considerable variation in different growth stages and yield at various sowing dates. All tested rice varieties took 40 days to reach the seedling stage on 15 December sowing. With the advancement or preceding this sowing date, the days required to attain this stage decreased. In mid-November sowing, the maximum period (33-34 days) was needed for tiller development and then reduced with the advancement of sowing dates irrespective of variety. Among the rice varieties, BRRI dhan89 required the highest time for panicle initiation (PI) on all sowing dates. The other three rice varieties took more or less similar time for panicle initiation. Among the rice varieties, BRRI dhan89 needed the highest, and BRRI dhan86 needed the lowest degree days for PI and flowering. BRRI dhan81 and BRRI dhan89 gave a higher grain yield from 15 November and 1 December sowing. BRRI dhan88 produced consistent grain yield throughout the sowing time. The fluctuations in PI stages' commencement indicate varietal characteristics, environmental conditions, and interaction between variety and environment. Bangladesh Rice J. 26 (2): 41-49, 2022

A better understanding of widespread agricultural practices adopted in the region of Ribeira Valley, São Paulo, Brazil for upland rice (Oryza sativa L.) production is needed. The objectives of this study were to determine the optimum sowing date and highest yielding genotypes for rice production. Treatments included four upland rice genotypes (ANA 5011, AN-Cambará, Moti-Amarelo, and Moti-Branco) and four sowing dates (October, November, December, and January) in 2011 and 2012. The results of the study showed that genotype ANA 5011 had the earliest maturity, while the Moti genotypes had the latest maturity in all sowing dates. The Moti genotypes were found to have greater plant height and 1,000-grain weight than the other two genotypes. In contrast, the Moti genotypes had fewer panicles m−2, fewer total filled and total numbers of spikelets panicle−1, and lower final yield. The genotype AN-Cambará had the highest number of tillers, filled and total number of spikelets panicle−1, panicle m−2, and the highest yield. Sowing in either November or December was found to be the most suitable dates for rice cultivation for all genotypes. In conclusion, the AN-Cambará genotype was found to have the highest yield potential for the region among all genotypes studied.

In the current study we reported for agronomic traits and yield of fifteen rice genotypes in season during 2018 and investigated at the field experimental of Al-Mashkab research station (AMRR), Najaf-Iraq. The experiment was conducted following Randomized Complete Block Design (RCBD) with having three replications. These data related days to 50% flowering and heading, plant height (cm), leaf area index (LAI), panicle length (cm), number of tiller per panicle, 1000 grain weight (g) and biological yield, harvest index and grain yield (kg ha-1) were evaluated. The results indicated that the rice genotypes differed in plant growth characteristics and yield and yield components. 1000 grain weight and grain yields both were highest in Gohar genotype. Shiroudi genotype required shorter days to maturity and Anber33 longest days to maturity. Some of the rice genotypes particularly (Gohar) showed high promise with grain yield. Recommended, intensification of introducing more genotypes to select the best rice genotype for Iraqi condition could maximize the benefits of genotype cultivation. Agronomic data collected in the current study would be significant to realize the suitability of an individual rice genotypes of the farmer field, also were found more appropriate of the agro climatic status of Iraq.
