Abstract/ Executive Summary:

A field experiment on French bean having three varieties (BARI Jhar Seem-1, BARI Jhar Seem-2 and Local) and six sowing dates at 10 days interval from November 01 to December 20) was conducted at the Agricultural Research Station, Raikhali, Rangamati Hill District during the Rabi seasons of 2004-05 and 2005-06 to find out the suitable variety and optimum sowing date for getting higher pod yield. Both the varieties of BARI Jhar Seem-1 and BARI Jhar Seem-2 yielded higher from local variety but the first two varieties were statistically at par in respect of pod yield. November 10 sowing was statistically at par with November 20 sowing gave the highest pod yield of French bean. BARI Jhar Seem –1and BARI Jhar Seem-2 produced maximum pod yield of French bean when sown on either November 10 or November 20.

Keywords: French bean, Varieties, Sowing dates, Pod yield

Location: Experimental Field of Agricultural Research station, BARI, Raikhali, Rangamati Hill District

Start Date: 00-11-2004

End Date: 00-04-2006

Program Area: Variety and Species

Commodity: Bean

Objectives:

To find out the suitable variety and optimum date of planting during Rabi season under south-eastern hilly region of Bangladesh.

Methodology:

The field experiments were carried out during the Rabi seasons of 2004-05 and 2005-06 at the Agricultural Research station, Raikhali, Rangamati Hill District, with 18 treatment combinations, comprising three varieties (V₁ = BARI Jhar Sheem-1, V₂ = BARI Jhar Sheem-2 and V₃= Local) and six sowing dates (D₁= November 01, D₂ = November 10, D₃ = November 20, D₄ = November 30, D₅ = December 10 and D₆ = December 20) in factorial randomized complete block design, replicated thrice. The soil of the experimental plot was sandy clay loam, having pH 5.5, organic matter 0.92%, total nitrogen 0.078%, available phosphorous 8.5 μg/g and available potassium 0.19 meq/100 g soil. The total rainfall during the crop period was 22.83 mm in 2004-05 and 69.55 mm in 2005-06. Sowing was done on scheduled time according to the treatments both in 2004-05 and 2005-06 in rows 30 cm apart, where two seeds were dibbled at 10 cm spacing. Seedlings were thinned 15 days after sowing keeping one seedling per hill. The crop was raised using 120 kg N, 60 kg P₂O₅ and 50 kg K₂O/ha during both the years of experimentation. Half dose of the nitrogen and full dose of phosphorous and potash was applied as basal in the form of urea, triple supper phosphate (TSP) and muriate of potash (MP), respectively. Remaining nitrogen was applied 30 days after sowing. The field was given one light pre-sowing irrigation in every planting date. The plants were earthing up up 35 days after sowing. The plots were kept weed free by manual weeding up to pod initiation stage and another two light irrigations were given 30 and 60 days after sowing. Ten plants were selected randomly in each treatment and all the growth and yield observations were recorded from them. The green pod was harvested four times from all the plots. At first the plot yield was recorded and then it was converted to per hectare yield in tons. The various observations recorded were statistically analyzed and the means were separated by least significant difference test (LSD).

Achievement/Findings:

It could be concluded from the study that during Rabi season Variety ‘BARI Jhar Seem-1 and BARI Jhar Seem-2 sown in the 2^nd or 3^rd week of November was most suitable for getting higher yields of French bean in eastern hilly areas of Bangladesh (AEZ-29).
