Abstract/ Executive Summary:

A study on the effect of irrigation on banana production cv. Sabri was conducted at the Regional Agricultural Research Station, Ishurdi during 1986-88. There were five treatments viz., no irrigation, one irrigation (December), two irrigation (December and February), three irrigation (November, January and March) and mulch only. Significant improvement was recorded in top girth, plant height, number of hands and fingers per bunch, circumference of fruit and fruit yield per plant by irrigation.

Keywords: Irrigation, Growth, Yield, Banana

Location: Regional Agricultural Research Station (RARS), Ishurdi

Start Date: 00-09-1986

End Date: 00-01-1988

Program Area: Crop-Soil-Water Management

Commodity: Banana

Objectives:

To find out the effect of irrigation on growth and yield of banana cv. Sabri.

Methodology:

The experiment was conducted at the Regional Agricultural Research Station (RARS), Ishurdi during September 1986 to January 1988. Banana cv. Sabri was included in this study. The unit plot size was 8m x 8m. There were 5 treatments viz., no irrigation (control), one irrigation (December), two irrigations (December and February), three irrigations (November, January and March) and no irrigation but with mulch. The irrigation was given at field capacity in the first week of the months in question. The experiment was laid out in RCBD with three replications. The suckers were planted in pits 2m apart; thus accommodating 16 plants per plot. Manures and fertilizers were applied @ 10kg cowdung, 300g urea, 250g TSP and 300g MP per plant. The full doses of cowdung and TSP were applied in the pits seven days before planting. Urea and MP were applied as top dressing in three equal installments at two months interval starting two months after planting. Mulching was provided by water hyacinth. Support was provided and the intercultural operations done as necessary. Data were recorded in respect of morphological and reproductive characters, analyzed statistically and means were separated by DMRT for interpretation.

Achievement/Findings:

The findings of the study lead to conclude that there is a critical moisture level below which yield in banana is adversely affected. That is why yield obtained by one irrigation, two irrigations and three irrigations was similar but significantly higher than the yield obtained by no irrigation or mulch only.
