Abstract/ Executive Summary:

Interaction 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. Fruits of all the treatments were harvested on 13 July 2014. Fruit length, diameter and thickness and edible portion did not differ significantly due to the combined effect of fertilizer and irrigation but number of fruits /plant, fruit weight, TSS and yield varied significantly. Maximum number of fruits (196/plant) and yield (59.28 kg/plant) were recorded from the plants treated with the treatment combination F₃I₂as compared to minimum fruits and yield (17/plant and 5.19 kg/plant, respectively) in the treatment combination of F₀I₁. Fruit weight was noticed maximum and identical in the treatment combinations of F₀I₂ (365.33 g) followed by F₂I₁ (360.67 g) which were statistically at par to those of F₂I₂ (352.50 g), F₁I₁ (331.67 g) and F₁I₂ (324.00 g). The treatment combination of F₂I₁ manifested the highest TSS (19.10%). The lowest TSS (16.03%) was recorded from the combination F₀I₁. Rest of the treatments exhibited the second highest and identical TSS.

Start Date: 01-09-2013

End Date: 31-07-2014

Program Area: Crop-Soil-Water Management

Commodity: Mango

Objectives:

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

To find out the appropriate fertilizer dose along with level of irrigation for mango production

To developed proper fertilizer doses and level of irrigation for higher yield and good quality 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.

There were two factors Factor A:- 4 doses of fertilizers-

F₁= 100 % of the fertilizer dose (N: 230.41 g, P: 50.00 g K: 100 g, S: 35.97 g, Zinc: 3.60, Boron: 3.40)

F₂=175 % of the fertilizer dose

F₃= 250 % of the fertilizer dose

F₀= Control (no fertilizer)

Factor B:- 2 level of irrigation

I₁= Two irrigations one at flowering stage and another one at pea stage of fruit

I₂= Irrigations at an interval of 10 days up to maturity of fruit

Irrigations 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:

Maximum number of fruits (196) and yield (59.28 kg) per plant were manifested from the plants treated with 250 % of the fertilizer dose along with level irrigation as compared to minimum number and yield (17/plant and 5.19 kg/plant, respectively) in the treatment combination of no fertilizer and two applications of irrigation one at flowering stage and another one at pea stage of fruit (F₀I₁).
