Abstract/ Executive Summary:

An experiment was conducted to investigate the effect of different horticultural practices for controlling mango antharcnose with achieving higher yield and quality of mango cv. Amrapali at the Germplasm Centre of the Fruit Tree Improvement Project (GPC-FTIP), Department of Horticulture, Bangladesh Agricultural University, Mymensingh during the period from July 2000–July2002. It was found that application of different horticultural practices effectively reduced the mango anthracnose. P+W+S produced the highest (47.34) number of healthy fruits per plant and the lowest (27.17) was obtained from control plant. The highest (10.26 t/ha) yield was obtained from P+W+S treated plant and the lowest (4.97 t/ha) was found from control plant. Second year x P+W+S treated plant resulted the highest (11.04 t/ha) yield and the lowest (5.40 t/ha) was found from 2nd year x control treated plant.

Keywords: Horticultural practices, Anthracnose, Quality, Yield, Mango

Location: Germplasm Centre (GPC), FTIP, Department of Horticulture, BAU, Mymensingh

Start Date: 00-07-2000

End Date: 00-07-2001

Program Area: Pest Management

Commodity: Mango

Objectives:

Objective of this study was to investigate the effectiveness of some cultural practices and their integration on the prevention of mango anthracnose.

Methodology:

The investigation was carried out in two years from July 2000 - July 2001 at Germplasm Centre (GPC), FTIP, Department of Horticulture, BAU, Mymensingh. The single-factor experiment was conducted in randomized complete block design (RCBD) with 3 replications. The treatments were pruning; weeding; spading; pruning + weeding (P+W); pruning + spading (P+S); weeding + spading (W+S); pruning + weeding + spading (P+W+S) and control. Infested twig, leaves, flowers, and fruits were removed after fruit harvest, before flowering and after fruit sets. Pruning, weeding and spading was done after fruit harvest, before flowering and after fruit sets. The plants were irrigated, weeded and fertilized regularly (as recommended in fertilizer recommendation guide, (BARC) as and when necessary following a uniform and recommended dose. The recorded parameters were fruit retention per inflorescence and per plant (%); total number of healthy fruits per inflorescence and per plant (%); total number of diseased fruits per inflorescence and per plant (%); total number of diseased fruits per inflorescence and per plant (%); disease incidence (%); % surface area infected per fruit; fruit weight (g) fruit size (cm), yield/plant; yield (t/ha) and total soluble solids (TSS). The benefit-cost ratio (BCR) analysis was calculated. Recorded data were analyzed statistically.

Achievement/Findings:

Disease incidence of anthracnose showed significant variation between the different year and horticultural practices. The highest (63.33%) incidence was found in 2^nd year x control treatment and the lowest (23.33%) from 2^ndyear x P+W+S treatment at 10 days after harvest. Fruit area diseased at different After Harvest (DAH) as influenced by different year and horticultural practices. The maximum (4.33%) fruit area diseased was found in 2nd year x control plant at 10 DAH and minimum (0.33) fruit area diseased was observed in 1^st year x P+W+S treated plant at same DAH.
