EFFECT OF SHADE AND SOWING METHOD ON ERYNGIUM FOETIDUM PRODUCTION

The experiment was conducted at two Regional Spices Research Stations at Gazipur and Magura during July 2012 to June 2014. Experiments were conducted following split plot design with six treatment of two factors of three different shades such as 1) Black mosquito net, 2) Cucurbit trellis and 3) Control (open) and two sowing methods such as i) line sowing with 10cm spacing and ii) Broadcasting were placed in the unit plot. The maximum number of harvested plants (655/m2) and fresh yield (28.52 t/ha) were obtained from broadcast sowing under nylon net shade at Joydebpur while line sowing without shade gave the minimum number of harvested plants (293/m2) and fresh plant yield (16.20 t/ha) at Magura. The maximum gross return (Tk. 4944.2 thousand/ha), net return (TK. 4438.2 thousand/ha) and BCR (1099) was obtained from nylon net shade in broadcast sowing and these was lowest (Tk. 1586.4, 1196.3 thousands/ha and 4.07, respectively) came from line sowing under cucurbits trellis. Cultivation of Eryngium under cucurbits trellis gave early returns that better for fresh leaf production. Open sunlight is less costly but it is not suitable for quality leaf production. Broadcasting sowing under nylon net shade seems better for leaf production and profit.

Coblation versus Diode Laser Tonsillectomy in Children: A Randomized Controlled Trial

Objective: This study aimed to compare the efficacy of diode laser and coblation tonsillectomy in paediatric patients in relation to operative time, amount of blood loss, post operative pain, healing of tonsillar fossa and returns to normal diet. Methods: A total of 200 patients ,100 for coblaton and 100 for diode laser, aged 3-12 years with recurrent tonsillitis with or without snoring and sleep apnoea were recruited. Participants were prospectively randomised to diode laser and coblation tonsillectomy. Operative time and blood loss were recorded. Pain was recorded by VAS or assessed by using analgesic. Results: The operative time were recorded 07-15 minutes,mean 10 minutes in coblation group and 12-20 minutes ,mean 14 minutes in laser group., Blood loss was recorded 0-15 ml mean 8 ml in coblation group and 10-25 ml mean 13.5 ml in diode laser group . However, at post-operative day seven, the diode laser tonsillectomy group had significantly higher pain scores compared with coblationtonsillectomy groups.Coblation group started normal soft diet on day 5 whereas diode laser started on day 8 Conclusion: Coblation tonsillectomy is associated with less operative time and blood loss, early returns to normal diet and less pain score in comparison to Diode laser tonsillectomy Bangladesh J Otorhinolaryngol; October 2017; 23(2): 140-145
