ABSTRACT

The present research was conducted at the farmer’s field of Madhupur during Rabi season 2018-19 to investigate the growth and yield performance of mustard mutants. The experiment was arranged in a randomized complete block design consisting of two mustard mutants (viz. RM-10, RM-18, BARI Sarisa 15) as treatment and replicated thrice. All the growth, yield attributes and yield were substantially influence among the mustard mutants except the phenological parameters. Results of the experiment showed that the highest plant height in RM-10 (104.00 cm) and RM-10 was found better in respect of maximum seed yield (1.78 tha^-1), number of branches (5.27) and thousand seed (4.03 g). Therefore, findings of this study suggested that RM-10 would be suitable for better productivity and recommended for cultivation at Madhupur region in Bangladesh.

ABSTRACT

A field experiment on efficacy of different organic manures on sustainable yield and soil fertility under cauliflower production was conducted in the Grey Terrace Soil (AEZ-28) of Gazipur during the years of 2018-19 to 2019-20. Snow white variety of cauliflower was used as test crop. There were eight treatments viz. T₁: Native nutrient, T₂: Poultry manure @ 10 t ha^-1, T₃: Cowdung @ 20 t ha^-1, T₄: Farm Yard Manure   @ 18 t ha^-1, T₅: Vermicompost @ 15 t ha^-1, T₆: Compost @ 15 t ha^-1, T₇: Tricho-Compost @ 10 t ha^-1,        T₈: Bioslurry @ 15 t ha^-1. Forty percent of recommended N and K fertilizer as common & basal doses applied in experimental field. The experiment was laid out in RCB design with three replications. Data revealed that, the T₅ treatment produced the highest average yield (42.0 t ha^-1) of the two years of cauliflower. This trend of influence was consistent for almost all the yield contributing characters of cauliflower. The native nutrient treatment produced the lowest average yield (13.32 t ha^-1). The average uptake of nutrients by cauliflower curd was highest in the treatment T₅ (vermicompost) which was followed to T₈ (Bioslurry) treatment. The lowest nutrient uptake was noted from T₁ (control) treatment. In post-harvest soil analytical results explored that application of different organic manure with minimum amount of chemical fertilizers enhances the soil fertility. The highest gross margin (4,03,700 Tk.ha^-1yr^-1) and MBCR (3.13) was noted from T₈ (Bioslurry) treatment.

ABSTRACT

A pot experiment was conducted at Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, during October 2012 to January 2013 to assess the salt tolerance of sorghum (Sorghum bicolor L.) genotypes viz. Safal 999, Debudoy, Jamboo, Hybrid Sorgo and Hybrid Sudan. The plants were grown under four salinity levels viz. control (0.42dSm^-1), 6 dSm^-1, 9 dSm^-1 and 12 dSm^-1. Plant height, Leaf Area Index (LAI), 1000-grain weight, grain yield plant^-1 and harvest index (HI) were decreased gradually with gradual increase in salinity levels. The genotype Hybrid Sorgo showed better performance than other genotypes at same salinity stress condition. Therefore, Hybrid Sorgo was found more tolerant to salinity.
