Abstract/ Executive Summary:

Influence 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 2018 to July 2019. 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 (irrigations one at flowering stage and another one at pea stage of fruit and irrigations at an interval of 10 days up to maturity of fruit) were included in the study as treatments. Number of fruit set per panicle and number of fruits at harvest were noticed the highest in the treatments 250 % (27.2) and 175 % (0.90) of the fertilizer dose, respectively. Control plants always exhibited minimum number of fruits per panicle. Fruits from all the treatments were harvested on 22 July 2019. Maximum number of fruits (190.0) and yield (71.3 kg) per plant were recorded from the plants treated with 250 % of the fertilizer dose combined with irrigations at an interval of 10 days up to maturity as compared to minimum fruits and yield (108.3/plant and 37.95 kg/plant, respectively) in the treatment combination of no fertilizer and two irrigations one at flowering stage and another one at pea stage of fruit. Maximum individual fruit weight (403.3 g) and TSS content (17.93 %) were observed from plants treated with 250 % of the fertilizer dose in combination with two irrigations one at flowering stage and another one at pea stage of fruit.

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Mango, Fertilizer, Irrigation scheduling

Objectives:

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

Methodology:

The experiment was performed at the Fruit Farm of Horticulture Research Centre, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during September 2018 July 2019. 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 irrigations one at full bloom and another one at pea stage of fruit and I₂: irrigations at an interval of 10 days starting from full bloom and continued up to maturity included in the study. 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. 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 with appropriate design of experiment (Gomez and Gomez, 1984) adopting a statistical package programme MSTAT-C. The treatment means were separated by Least Significant Difference (LSD) test at 5 % level of significance.

Achievement/Findings:

The result reveals that plants received 250 % of the fertilizer dose (100 % 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) combined with irrigations at an interval of 10 days up to maturity resulted in maximum number of fruits (190.0) and yield (71.3 kg) per plant compared to minimum fruits and yield (108.3/plant and 37.95 kg/plant, respectively) from the treatment combination of no fertilizer and two irrigations one at flowering stage and another one at pea stage of fruit.
