Abstract: In this study, the effects of different irrigation levels with bio-stimulant applications on leaf area, crown diameter, number of crown, leaf number and plant width were investigated in a variety of Kabarla. The trail was implemented as a 4×2 factorial scheme (irrigation levels and bio-stimulant use), in split plot design with 6 consequent months at 4 replicates, totaling 32 plots. Bio-stimulant applications were designed as main plot and different irrigation levels were arranged as sub plot. Strawberry plant was subjected to four irrigation water levels (Ir125, 1.25 Ep; Ir100, 1.0 Ep; Ir75, 0.75 Ep; Ir50, 0.50 Ep). Bio-stimulant applications were investigated on morphological parameters with compared by control plot. As a result of the experiment, irrigation levels and growing period influenced the leaf area, crown diameter, plant width, number of crown and leaf number. Bio-stimulant application just positively affected the number of leaf, while other parameters were not affected by the application. All examined parameters were taken same statistical group except of IR50 which negatively affected plant growth. Also as expected, all plant vegetative part increased with time and this increase was determined statistically significant among months. As a result of these data, IR75 irrigation level could be recommended in terms of optimal vegetative growing combined with bio-stimulant applications.

Abstract: A field trial was conducted on screening sugarcane genotypes against wilt disease at Bangladesh Sugarcane Research Institute (BSRI) farm, Ishurdi during the cropping season 2014-15 and 2015-16. Thirty four sugarcane genotypes were inoculated by the mixed inocula of 8 different isolates of wilt pathogen following hypodermic syringe method. Among them, 20 were found as resistant, 10 were moderately resistant, 2 (Isd 16 and Isd 28) were moderately susceptible and 2 (Isd 18 and Isd 19) were found as susceptible to wilt disease.

Abstract: A study was conducted at Sher-e-Bangla Agricultural University, Dhaka during September 2009 to March 2010 to determine the quality and health status of okra seed collected from different sources and locations of Bangladesh. Different sources were government organization, namely BARI, Gazipur and BADC, Dhaka, eight seed companies and ten farmers of different districts. Seed collection and quality analysis exposed that moisture content of seed samples ranged from 8.37-14.95% and 9.97-13.71% in terms of source and group of seed collection. Germination percentage of government organization seeds, seed companie’s seeds and farmers saved seeds was 86.52, 82.71 and 53.74%, respectively. Purity percentage varied from 87.86 to 99.70% in different sources. Purity percentage of government organization seeds, seed company’s seeds and farmers saved seeds were 94.57%, 99.41% and 92.45%, respectively. In government organization seeds, both vigor index (2273.0) and 1000-seed weight (59.59g) were found higher than the Seed companies and farmers saved seeds. In seed health study, seven fungi, namely Fusarium spp., Colletotrichum dematium, Aspergillus flavus, A. niger, Rhizopus stolonifer, Bipolaris spp., and Curvularia spp. were found in the seed samples. The highest mean incidence of fungi in okra seeds was recorded from farmer seeds (16.31%) followed by seed companies (13.33%) and the lowest from government organizations (11.81%).

Abstract: Foliar spray of fertilizer does not only increase the crop yields but also reduce the quantities of fertilizer applied through soil. An attempt was taken to find out the efficacy and economic benefit of urea spray technology for getting higher yield using a local rice cultivar Haridhan and a modern rice cultivar BRRI dhan56. The research work was conducted at the Agronomy Field Laboratory, Department of Agronomy, Bangladesh Agricultural University, Mymensingh during the period from July to November 2015. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Results revealed that foliar spray of urea solution had significant effect on several yield contributing characters. It was found that treatment T4 (where 50% of the recommended dose (RD) of urea was applied directly to soil by 2 equal splits and 20% of the RD of urea was applied as foliar spray with three equal splits at 30 DAT, 45 DAT and 60 DAT) gave significantly higher number of effective tillers hill-1, number of grains panicle-1, grain yield, straw yield and biological yield than that of any other treatments. Both the varieties gave significantly higher yield with the treatment T4. In case of cost effectiveness, it was found that treatment T1 (where no urea was applied) exerted lowest cost of production (60,124 BDT ha-1), but, treatment T4 provided highest gross income (122,800 BDT ha-1), net income (60,436 BDT ha-1) and benefit cost ratio (1.97) as well as lowest cost per unit of product (5.27) for the varieties. The highest cost of production was found in case of treatment T6 where traditional method of urea was applied. Therefore, the present study concluded that about 30% recommended dose of urea/ha can be saved in each rice growing season by applying urea as foliar spray.

Abstract: Haematococcus is a genus of unicellular green microalgae and it is known as an important resource of keto-carotenoid: Astaxanthin. In this work, a strain of Haematococcus sp. grew rapidly when cultivated in BBM medium under different light intensities from 30 to 120 μmol photons.m-2.s-1. Production of antioxidant compounds (carotenoid and phenolic compounds) as well as total antioxidant capacity and lipid accumulation of Haematococcus sp. increased with increase in light intensity especially after 21 days of cultivation. The results demonstrated that there was significant relation between production of carotenoid, phenolic compound and lipid accumulation in Haematococcus microalgae under high light cultural conditions.
