摘要

This study aimed to evaluate the morphological, biochemical, yield-related, and economic traits of eight pineapple (Ananas comosus) genotypes under litchi–pineapple agroforestry conditions in Moulvibazar, Bangladesh. The experiment was conducted during 2023–2024 in a randomized complete block design (RCBD) with three replications. Eight genotypes (AC AKB 001–007 and ‘MD-2’) were assessed for plant growth, fruit characteristics, and chemical properties. Data were analyzed using analysis of variance for normally distributed traits and Kruskal–Wallis tests for non-normal traits, followed by appropriate post-hoc comparisons. Significant genotypic variation (p < 0.05) was observed across most morphological and chemical traits. Fruit weight ranged from 0.029 kg (‘AC AKB 007’) to 0.665 kg (‘Giant Kew’). Vitamin C content varied between 11.88 mg/100 g (‘AC AKB 002’) and 27.15 mg/100 g (‘MD-2’), while total soluble solids (TSS) values ranged from 7.63°Brix (‘Giant Kew’) to 15.87°Brix (‘AC AKB 003’). Yields differed significantly (p = 0.003), with ‘AC AKB 002’, ‘Giant Kew’, and ‘MD-2’ producing the highest (12.0–12.33 t/ha) and ‘AC AKB 007’ the lowest (4.33 t/ha). Economic analysis showed that ‘AC AKB 002’ and ‘Giant Kew’ achieved the highest net present value (50.97), while ‘AC AKB 003’ and ‘AC AKB 007’ exhibited superior IRR and BCR values. The findings highlight substantial genetic variability influencing productivity and fruit quality. ‘Giant Kew’, ‘MD-2’, and ‘AC AKB 002’ are promising for yield, while ‘AC AKB 003’ and ‘AC AKB 007’ demonstrate strong economic efficiency. These results provide empirical evidence for genotype-specific recommendations to enhance profitability and sustainability in pineapple-based agroforestry systems.
