The research was conducted at the Agronomy Field Laboratory (240 22'36" N Latitude, 88038'27" E Longitude and 20 m altitude), Department of Agronomy and Agricultural Extension, University of Rajshahi, Rajshahi, Bangladesh during the period from July to December 2007. The experimental site was under the humid tropical climate which is characterized by heavy rainfall, high humidity and high temperature during monsoon and scanty rainfall, low humidity and low temperature during winter. The land was medium high belonging to the calcareous dark grey flood plain soil type (Gangetic Alluvial Soil Tract). The soil properties of the field were pH 8.6, organic matter 0.48%, total available nitrogen 0.04%, available phosphorus 11.25ppm, available potassium 58 ppm and available sulphar 25.65 ppm. The treatments of the experiment include three rice varieties viz. Kataribhog, Kalijira and Chiniatop and six spacings viz. 15cmx15cm, 20cmx15cm, 25cmx15cm, 30cmx15cm, 35cmx15cm and Haphazard. The experiment was laid out in a randomized complete block design (RCBD) with three replications.The unit plot size was 10 m2 (4mx2.5m). The seeds were sown in nursery bed on 6`11 July, 2007.The experimental land was uniformly fertilized with nitrogen (N), phosphorous (P205), potash (K20), sulphur and zinc fertilizers @ 60, 40, 40, 10, 5 kg ha-1 respectively, as urea, triple super phosphate, muriate of potash, gypsum and zinc oxide. The whole amount of triple super phosphate, muriate of potash, gypsum, zinc oxide and 1/3 of urea were applied as basal dose during final land preparation. The 2/3 amount of Urea was applied as topdressing in two equal splits. The first split was applied at active tillering stage at 30 DAT (days after transplanting) and the second split was applied before panicle initiation stage. Finally, 30-day old seedlings of the three varieties were transplanted in the well-puddled plots as per foresaid spacing with two seedlings hill-1 on 5 August, 2007.
Kataribhog, Kalijira and Chiniatop were harvested at maturity on 11th November, 5111 December and 6111 December respectively. Data were recorded on yield parameters at final harvest. The collected data were analyzed statistically using the analysis of variance (ANOVA) technique and the mean differences were adjudged by Duncan's New Multiple Range Test (Gomez and Gomez, 1984) with the help of MSTAT software.
