Abstract/ Executive Summary:

Effect of fertilizer and irrigation on the yield and quality of mango was studied at the Fruit Research Farm of Horticulture Research Centre, BARI, Joydebpur, Gazipur during the period from August 2013 to July 2014. Three different levels of fertilizer (100 % of the fertilizer dose (Cowdung: 25 kg; N: 230.41 g, P: 50.00 g, K: 100.00 g, S: 35.97 g, Zn: 3.60 g, B: 3.40 g), 175 % of the fertilizer dose, 250 % of the fertilizer dose) and control along with two levels of irrigation (irrigation one at flowering stage and another one at pea stage of fruit and irrigation at an interval of 10 days up to maturity of fruit) 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 irrigations; one at flowering stage and another one at pea stage of fruit- manifested the highest TSS (19.10%).

Keywords: Mango, Fertilizer, Irrigation, Yield and quality

Location: Fruit Research Farm of Horticulture Research Centre, BARI, Joydebpur, Gazipur

Start Date: 00-09-2013

End Date: 00-07-2014

Program Area: Crop-Soil-Water Management

Commodity: Mango

Objectives:

1. To investigate on the effects of fertilizer and irrigation on mango fruit retention and yield

2. To determine quality of mango as may be influenced by the application of the said inputs.

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. A total of 1761 litre of water in I₁ and a total of 6860 litre of water in I₂ were applied during the period from mid March to late May 2014 at an interval of 10 days.Adequate care and management of the plants in the experiment were taken as per need. Two sprays; First spray with Tilt @ 0.5 ml/L and Ripcord @ 1 ml/L was applied before flower opening and after panicle emergence and the second spray was done at the pea stage of fruits. 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 adopting a statistical programme ,MSTAC-C. The treatment means were separated by LSD test at 5 % level of significance.

Achievement/Findings:

Maximum number of fruits (179/plant) and yield (55.10 kg/plant) were obtained 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 irrigations; one at flowering stage and another one at pea stage of fruit manifested the highest TSS (19.10%).The experiment will be continued for confirming the result.
