Abstract/ Executive Summary:

An experiment was conducted to study germination response to ambient temperature in raising sugarcane settlings. The highest germination was recorded in single-budded setts planted in poly bag. Higher germination was obtained in single-budded setts compared to two-budded setts planted in soil bed. Temperature directly affected both rate and speed of germination, and minimum temperature should not be below 20°c for good germination. Rate and speed of germination decreased as the ambient temperature dropped. Varietal difference exists on rate of germination but not in speed of germination. The variety L.Jaba-C was found relatively cold tolerant compared to variety Isd-16. Therefore, it may be suggested to use single-budded setts especially in polybag and the variety L.Jaba-C during cold period for higher germination

Program Area: Crop-Soil-Water Management

Commodity: Sugarcane

Objectives:

To study germination response to ambient temperature in raising sugarcane settlings.

Methodology:

An experiment was carried out at Sugarcane Research and Training Institute. (SRTI) farm with two commercial sugarcane varieties such as Isd-16 and L.Jaba-C. The treatments were as follows:- T₁= Single-budded setts planted in polythene bag (Polybag). T₂ = Two-budded setts planted in soil bed horizontally. T₃ = Single-budded setts planted in soil bed horizontally (SB-horizontal). T₄ = Single-Budded setts planted in soil bed vertically (SB-vertical). In each fortnight, a set of 200 buds of each variety in each treatment was planted starting from first July, and continued upto 15th February, Germination percentage was recorded at an interval of 7d starting from 7d after planting until obtaining maximum percentage of emergence, Similar soil moisture level and other growth factors were maintained during the whole experimental period, Ambient temperature data were collected from Biometry and Statistics Division of SRTI.

Achievement/Findings:

The results show that germination is affected due to method of sett preparation and its planting. The Single-budded sett preparation and polybag method of settlings raising may give better germination. Temperature directly affects both rate and speed of germination, and minimum temperature should not be below 20°C for good germination. The variety L.Jaba-C is relatively cold tolerant and higher germination can be obtained using L.Jaba-C under lower temperature.
