Abstract/ Executive Summary:

Effect of fertilizer and irrigation on the yield and quality of mango was studied at the Fruit Research Farm of HRC, BARI, Joydebpur, Gazipur during the period from August 2013 to July 2014. Three different levels of and control along with two levels of irrigation were included in the study as treatments. Maximum number of panicle per plant was noticed in the plants treated with 250 % of the fertilizer dose (202.33). Higher number of panicle per plant (109.08) was recorded when irrigation were applied at an interval of 10 days up to maturity of fruit. At harvest, the highest fruit retention per panicle was recorded in the plants treated with 250 % of the fertilizer dose (1.18) followed by 175 % of the fertilizer dose (1.05) and 100 % of the fertilizer dose (1.00). Maximum number of fruits (179/plant) and yield (55.10 kg/plant) was noted from the plants treated with 250 % of the fertilizer dose as compared to minimum (28/plant and 9.91 kg/plant, respectively) in the control. The treatment combination of 175 % of the fertilizer dose and two irrigation one at flowering stage and another one at pea stage of fruit manifested the highest TSS (19.10%).

Keywords: Mango, Fertilizer, Irrigation, Fruit growth

Start Date: 01-09-2013

End Date: 30-06-2014

Program Area: Crop-Soil-Water Management

Commodity: Mango

Objectives:

To investigate the effects of fertilizer and irrigation on yield and quality of mango.

To find out the appropriate fertilizer dose and level of irrigation for mango

To developed proper fertilizer application package as well as level of irrigation for higher yield of mango.

Methodology:

The experiment was conducted at the Fruit Farm of Horticulture Research Centre, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during September 2013 July 2014. BARI Mango-4 was used in the study as variety. The experiment was laid out in a randomized Complete Block Design (Factorial) with 3 replications. Three doses of fertilizers i.e. 100 % (N: 230.41 g, P: 50.00 g K: 100 g, S: 35.97 g, Zinc: 3.60, Boron: 3.40), 175 %, 250 % and control (no fertilizer) along with two types of irrigation i.e. I₁: two irrigation one at full bloom and another one at pea stage of fruit and I₂: irrigation at an interval of 10 days starting from full bloom and continued up to maturity included in the study. Irrigation were applied considering the effective soil depth of 1.20 m and a diameter of 1.00 m. Bulk density and field capacity was measured. Adequate care and management of the plants in the experiment were taken as per need. The data on the following parameters plant height, base girth, canopy spread, length of terminal shoot at flowering, number of leaves per terminal shoot at flowering, length of panicle, number of secondary branches per panicle, date of first and last panicle appearance, number of panicle per plant, date of full bloom, fruit retention per panicle at an interval of 7 days up to harvest, fruit characters, TSS and yield were recorded. The collected data were tabulated and statistically analyzed with appropriate design of experiment (Gomez and Gomez, 1984) adopting a statistical programme MSTAC-C. The treatment means were separated by Least Significant Difference (LSD) test at 5 % level of significance.

Achievement/Findings:

It was revealed that the plant treated with 250% fertilizer gave 6 times higher fruits/plant and 5.5 times higher yield of mango than the plant treated with no fertilizer. On the other hand number of fruits per plant, fruit weight, fruit size, edible portion and yield per plant were found higher in the plant treated with irrigation at an interval of 10 days up to maturity of fruit than the plant treated with two irrigation one at flowering stage and another one at pea stage of fruit.
