Abstract/ Executive Summary:

An experiment was conducted et the Bangladesh institute of Nuclear Agriculture Farm, Mymensingh to find out the optimum planting time for three cauliflower cultlvars viz. Agrahayani, Pouaali and Early enowball. Dates of planting were Sep. 15, Sep. 30, Oct. 15 and Oct.30. It was observed that the aver age plant height,number of leaves per plant at harvest, area of the largest leaf. size and weight of the curd and marketable yield per hectare were influenced significantly by the date of planting. Three cultivars also showed wide variation in all aspects. The earlier planting •hawed better performance in all the parame ters. The highest yield was obtained from the earliLr planting and a successive decrease in yield was in late planting. The cultivar Pousali was the maximum curd yielder followed by Agrahayani and Early snowball.

Start Date: 00-08-1987

End Date: 00-01-1988

Program Area: Crop-Soil-Water Management

Commodity: Cauliflower

Objectives:

To find out the optimum planting time for different cauliflower cultivars.

Methodology:

The experiment was conducted at the Bangladesh institute of Nucler Agriculture Farm, Mymensingh during the period from August 1987 to Janu- ary 1988. The soil belongs to Non-calcareous Dark Grey Flood Plain having silt loam texture. Average organic matter, carbon and nitrogen contents were 1.9,0.6 and 0.06 percent, respectively and pH value ranged from 5.6 to 7.4 (FAO, 1971) . The four dates lof planting.Sept5,Sept.30,0ct.15 and Oct.30 were used as experimental treatments and the three cultivars of cauliflower namely, Early snowball, Agrahayani and Pousali were used as experimental material. The 6 sq. m.and the planting distance was 60 em x 50 em. Fertilizers were applied at the rate of 15 ton cow dung, 250 kg urea, 175 kg TSP and 176 kg MP per hectare. Usual cultural practices including irrigation were done as and when needed.Harvesting of the crop was done from November 23, 1987 to January 4,1988 depending on maturity and curd yield was recorded from each plot and converted to yleld/ha. Data on plant height, number of leaves per plant, length and breadth of largest leaf, size (diameter) of mature curd and individual curd weight was recorded after the crop was harvested,The number of leaves that was present in the plant at the time of harvest was considered as the number ot leaves per plant. Results were analyzed statistically and the differences between means were tested following LSD test.
