Abstract/ Executive Summary:

Three cultivars of barley namely Centinella, Ap-1-19 and Ap-1-20 were tested at BARI,Joydebpur during 1987-88 for five different sowing dates from November 5, with 15 days interval under irrigated condition to ascertain the optimum sowing time. November 5 was found to be optimum sowing for Ap-1-19 and November 5 to December 5 for Centinella and Ap·1·20. The cultivar Centinella was found to be superior and produced consistently higher grain yield up to late planting (December 5).

End Date: 00-00-1988

Program Area: Crop-Soil-Water Management

Commodity: Barley

Objectives:

To see the performance in relation to sowing dates of Barley.

Methodology:

The experiment was conducted at the research station of Bangladesh Agricultural Research Institute (BAR!), Joydebpur, Gazipur during the rabi season of 1987-88. The soil texture of the experimental plot was silty clay loam. The experiment was laid out In a split plot design with three replications. Five dates of sowing (Novem-Sowing date effects on barley sowing dates and a second irrigation at heading stage were also given. Seeds were sown at the rete of 80 kg ha^-1 in 30cm row spacing. Data on different plant characters were taken and analyzed.

The maximum and ley (Ap-1-19,Ap-1-20 and Centinella) minimum temperatures varied between in sub-plots. Unit plot size was 5m x 3m· 25.3 to 38.4°C and 12.9 to 28.2°C Fertilizers were applied at the rate of 60- respectively.
