Abstract/ Executive Summary:

An experiment was conducted to determine the effect of planting time on flowering of sugarcane. The variety Isd-16 was planted in five different dates starting from 15^th November, 1983 to 15^th March, 1984. Each time setts were planted with one month interval. In each treatment data were recorded on number of millable stalk, percent flowering stalk and first date of flowering. Different planting dates showed no effect on flowering time under SRTI climatic conditions. Maximum millable and flowering stalks were produced by November planting. Planting may be continued upto February.

Keywords: Flowering stalk, Sugarcane, Planting time

Location: Sugarcane Research and Training Institute, Ishurdi, Pabna, Bangladesh.

Start Date: 15-11-1983

End Date: 15-03-1984

Program Area: Crop-Soil-Water Management

Commodity: Sugarcane

Objectives:

To determine the effect of different planting dates on time of flowering and number of flowering stalk.

Methodology:

The variety Isd-16 was used as planting material which profusely flower between first and second week of November every year depending on climatic conditions. Single eye-budded setts were planted in 4"x 2" PVC pipe, filled with soil, using five planting dates starting from 15^th November, 1983 to 15^th March, 1984. Each time 150 buds were planted with one month interval. After one month of plantation, among the germinated buds, 72 more or less uniformly grown, good looking healthy settlings were transplanted in a well prepared field. The settlings were transplanted in a 3mX4.5m plot with four replications using randomized block design. In each plot, 18 settlings were transplanted in 3 rows. They were spaced 1.5 metre and 50 cm between and within rows, respectively. Normal cultural practices were done. In each treatment, data were collected from whole plot on number of millable stalk, percent flowering stalk and first date of flowering. In each case mill able and flowering stalks were recorded during the month of September, 1984 and last week of January, 1985, respectively. Number of days to first flower were . counted from the date of planting of setts to the date of emergence of flower.

Achievement/Findings:

The work suggests that flowering time can not be changed through changing planting date under SRTl climatic conditions. November planting was suitable time for maximum production of flowering stalk. For hybridization purposes plantation may be continued upto February.
