Abstract/ Executive Summary:

Keywords: Triticum aestivum, Seed storage conditions, Growth and yield

Location: Agronomy field, Sher-e-Bangla Agricultural University, Bangladesh.

Start Date: 00-11-2011

End Date: 00-03-2012

Program Area: Postharvest and Agro-processing

Commodity: Wheat

Objectives:

To investigate the response of different seed storage conditions on production of BARIGom-24.

Methodology:

An experiment was conducted at Agronomy field, Sher-e-Bangla Agricultural University, Bangladesh from November, 2011 to March 2012 to investigate the response of different seed storage conditions on production of BARIGom-24. Four different seed storage conditions viz. C₁: below 10°C, C₂= below 20°C, C₃= Polybag (room temperature) and C₄=Tin container (room temperature) were used on experiment following Randomized Complete Block Design with three replications. The unit plot area was 4 m × 2.5 m, plot to plot and block to block distances were 0.5m and 1.0 m, respectively. Moisture status and Germination percentage of seeds were recorded in every month from July to November, 2011. Fertilizers were applied at the rate of 100, 80, 30 and 20 kg ha^-1 of N, P, K and S respectively and 5 t ha^-1cowdung. The 2/3rd urea and whole amount of other fertilizers were applied as basal dose and rest 1/3^rd urea was applied at crown root initiation stage (21 DAS) followed by an irrigation. Seeds were treated (with Provex 200 @ 3 g kg^-1) of seeds before sowing @ 125 kg ha^-1and were placed in 20 cm apart lines. Data were collected from 10 randomly selected wheat plants from each plot. Crop of each plot was harvested from 4m2 areas leaving the border lines to record the seed yield which was converted into t ha^-1. Data were collected on plant height, number of tillers (linear), dry weight plant^-1, spike length, number of spikelets spike^-1, number of filled grains spike^-1, 1000-grain weight, grain yield, straw yield, biological yield and harvest index. The plants with roots were collected at different days after sowing from each plot and then oven dried at 70° C for 72 hours. The dried samples were then weighed and averaged. Dry weight was taken from 10 plants collected from inner rows of each plot. Thousand seeds were counted from seed sample and weighed at about 12% moisture level using an electric balance. After threshing, proper drying (12% moisture level) and cleaning, yield of each sample plot was recorded and values were converted to t ha^-1. Biological yield was determined by addition of grain yield and straw yield. Harvest index was determined by dividing the grain yield by total biological yield and multiplying by 100. Collected data were statistically analyzed by weight MSTAT–C software computer package program and mean differences were evaluated by Duncan’s Multiple Range Test (DMRT) at 5% level of probability.

Achievement/Findings:

Storage of seed at below 10°C and 20°C temperature showed better performance. So seed storing comparatively lower temperature provide better growth and yield of wheat.
