“…The two genotypes, T93 and K2 also recorded superiority in the trait of grain yield during the 2020 and 2021 planting seasons, with higher values for grain yield at the late date compared to the early planting dates. This is consistent with the findings of some researchers on significant variation in their studies on the genotypes of rice in seasons (Zaid et al, 2022) and locations (Musa et al, 2021) and different dates (Ali et al, 2019).…”

Selecting the appropriate date for planting rice can be one of the viable solutions for proper growth and development of rice to avoid unsuitable conditions that can lead to lower productivity. Two experiments were conducted in the field of Al-Mishkhab Rice Research Station in Najaf City / Iraq during 2020 and 2021. In each season, eight genotypes used and two germination dates (15 and 30 Jun). After 20 days, seedlings were transferred to the field and planted on 5th and 20th of July respectively. The experiment was based on a three-blocks in RCBD design to study the performance of eight genotypes at two planting dates in two seasons. Results showed significant differences for genotypes and planting dates for all traits, while seasons showed significant differences only for the number of days to 50% flowering and panicle length. The values of heritability in the broad sense (h2BS %) were medium for all studied traits, which in turn led to an increase in the values of expected genetic advance as a percentage of the general mean (GA %), which was slightly high for grain yield (13.66 %). The genotypes showed a significant response to the late sowing date of 20th July compared to the early date of 5th July in the two growing seasons for most of the studied traits, including grain yield. The stability of the genotypes in four environments was highly variable. Genotype T93 had the most stable grain yield and the highest 1000-grain weight, while Forat1 showed a response to late sowing. Furthermore, the Forat1 responded to suitable environmental conditions of the number of days to 50% flowering, 1000-grain weight, and grain yield. Therefore, the genotypes which have superiority and stability over various environments could be successfully used as crucial material in the future breeding programs.

“…Lentil (Lens culinaris) is the second most important pulse crop in Bangladesh (Ali et al, 2003). Pulses are the cheapest source of proteins and Indians fulfill 20 to 30 per cent of their protein requirement from pulses (Grover and Singh, 2015).…”

Background: Foot and root rot disease caused by Sclerotium rolfsii is a destructive soil borne disease of lentil (Lens culinaris). The present experiment was conducted to determine the inhibitory effect of thirteen plant extracts and two bio-control agents on in vitro mycelium growth of S. rolfsii. Methods: The experiment was conducted in the Laboratory of Pulse Research Center, RARS, BARI, Ishurdi, Pabna, Bangladesh during rabi season in 2015. Seven isolates of S. rolfsii were collected from foot and root rot affected lentil plant. Antifungal activity of thirteen botanicals and two biocontrol agents (T. harziznum and T. viride) was tested against a fast growing isolate (Sc-38) of the pathogen following poisoned food technique. Result: Out of thirteen botanicals, only Black cumin inhibited colony growth of S. rolfsii, where the colony diameter ranged 0.00-6.00 cm at different days after incubation. A moderate inhibition was achieved with Tulsi at 3, 6 and 9 DAI compared to control. Amendment of PDA with compost and liquid T. harziznum and T. viride remarkably inhibited the colony growth of S. rolfsii compared to control. Efficacy of four treatments of biocontrol agents was much better than botanical treatments. Two botanical extracts (Black cumin and Tulsi) and biocontrol agents (T. harzianum and T. viride) were found effective against S. rolfsii.
