Abstract/ Executive Summary:

A field experiment was conducted at the Regional Agricultural Research Station (RARS), Hathazari during the rabi seasons 2005-2006 and 2006-2007 to study the effect of irrigation and phosphorus placement on the yield and water use efficiency of french bean (Phaseolus vulgaris L.). Twelve treatment combination comprising 4 levels of irrigation (I0: no irrigation, I1: one irrigation at vegetative stage, I2: two irrigation; the first one at vegetative and the second one at flowering stage and I3: three irrigation; the first one at vegetative, the second one at flowering and the third one at pod development stage) and 3 levels of phosphorus placement (P1: broadcast, P2: same furrow placement and P3: side placement) were assigned in a split plot design with three replications. The significantly highest pod yield (11.94 t ha-1) was obtained with three irrigation (I3). The maximum number of pods per plant (14.31) was recorded with treatment P2 (same furrow placement). Pod weight per plant was found maximum (42.09 g) in the same treatment. The highest significant pod yield (11.56 t ha-1) was recorded with treatment P2. The interaction effect of irrigation and phosphorus placement was found not significant. However highest pod yield (12.06 t ha-1) was obtained from P2I3 treatment.

Keywords: French bean, Irrigation, Water use efficiency

Location: Regional Agricultural Research Station (RARS), Hathazari

Start Date: 00-00-2005

End Date: 00-00-2007

Program Area: Crop-Soil-Water Management

Commodity: Water management, Fertilizer, French bean

Objectives:

The irrigation and phosphorus management influences production of French bean. Different irrigation levels and depth of P placement increases the yield of pea (IARI, 1997). The present investigation has been therefore under taken to find out the appropriate irrigation schedule and phosphorus placement method for French bean production.

Methodology:

A field experiment with french bean was conducted at the Regional Agricultural Research Station (RARS), Hathazari, (AEZ-18) during rabi seasons 2005-2006 and 2006-2007. Twelve treatment combination comprising 4 levels of irrigation (I0: no irrigation, I1: one irrigation at vegetative stage, I2: two irrigations; the first one at vegetative and the second one at flowering stage and I3: three irrigations; the first one at vegetative, the second one at flowering and the third one at pod development stage) and 3 levels of phosphorus placement (P1: broadcast, P2: same furrow placement and P3: side placement) were assigned in a split plot design with three replications. Phosphorus placement was assigned in the main plot and irrigation in the sub plot. The unit plot size was 4 x 3 m2 and planting space was 25 cm x 15 cm.

Fertilizer was applied at the rate of 150-50-80-10-2 and 1 kg ha-1 of N, P, K, S, Zn and B, respectively. One third nitrogen and the whole amount of N, P, K, S, Zn and B was applied during final land preparation and remaining nitrogen was applied in two equal splits at 25 and 40 DAE. The experiment was sown on 10 November, 2006 with variety BARI French bean-2. Harvesting was started on 27 February and continued up to 07 March, 2007. Data on yield and yield contributing characters were recorded and statistically analyzed.

Achievement/Findings:

From two years result, it may be recommended that three irrigations; the first one at vegetative, the second one at flowering and the third one at pod development stage and same furrow placement of phosphorus are suitable for french bean cultivation in Young Meghna Estuarine Floodplain (AEZ-18) soils.
