Abstract/ Executive Summary:

An experiment was conducted at the Horticultural farm, Sher-e-Bangla Agricultural University to evaluate the influence of foliar application of calcium concentrations on strawberry during the period of November 2012 to February 2013 following Completely Randomized Design (CRD) with five replications. RABI-3 variety was used in the experiment. Three concentrations of calcium (Calcium Oxide, CaO) viz. 0 ppm (C₀), 50 ppm (C₁) and 100 ppm (C₂) were sprayed at 15 and 45 days after days after transplanting. Foliar application of calcium at the rate of 100 ppm caused early flowering (72.5 days) and fruit harvesting (96.2 days). C₂ (100 ppm) provided maximum number of fruits (20.00 plant^-1), maximum single fruit weight (14.2 g) and maximum percentage of brix (10.2%). Besides, 100 ppm foliar application of calcium provided minimum (12.3%) abnormal fruit while control provided the maximum (31.9%).

Start Date: 00-11-2012

End Date: 00-02-2013

Program Area: Crop-Soil-Water Management

Commodity: Strawberry, Fertilizer

Objectives:

To evaluate the influence of foliar application of calcium concentrations on strawberry

Methodology:

An experiment was conducted at Horticultural Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the month of November 2012 to February 2013 following Completely Randomized Design (CRD) with five replications. The recommended amount of soil and cowdung were mixed and pots were filled 7 days before transplanting. No chemical fertilizers were used on the experiment. For the experiment RABI-3 variety was used. The agronomic management were done as per recommendation of Bangladesh condition. Calcium (Calcium Oxide, CaO) was sprayed at three concentrations viz. 0 ppm (C₀), 50 ppm (C₁) and 100 ppm (C₂). These three concentration was sprayed two times, first at 15 days after transplanting and second at 45 days after transplanting of strawberry plantlets. Data were collected on plant height, number of leaves, number of runner, days taken to first flowering, days taken to first fruit harvesting, number of flower plant^-1, number of fruit plant^-1, percentage of physiological disordered fruit, fruit length, fruit diameter, single fruit weight, yield plant^-1 and percentage of brix. Digital caliper (DC-515) was used for measuring fruit diameter. Collected data were statistically analyzed using MSTAT-C computer package program then mean was calculated and analysis of variance for each of treatment was represented by F-test (Variance Ratio). Differences between treatments were evaluated by Least Significance Difference (LSD) Test at 5% level of significance.

Achievement/Findings:

Foliar application of calcium can improve the yield by reducing the percentage of abnormal fruit. The percentage of brix was also increased by the foliar application of calcium.
