This study aims to explore the relationship between home gardens' sizes and species richness of horticultural crops and to study the distribution of mango varieties in the selected area. Sixty home gardens were studied from September, 2018 to October, 2019 in Nay Pyi Taw Union Territory, Myanmar. Drone was used to generate geographical information. Coordinate points of each mango variety was collected. Information on compound dimensions and crop plants namely local names, growth stages, numbers of individual, leaf attitudes and characters were collected. Shannon-Wiener' index was employed to determine species richness. Distribution maps of mango varieties were developed. The compound areas could be classified into three classes as small, medium and large; were not correlated with species richness of all horticultural crops, but there had significant correlation with richness of mango varieties (p = 0.01, r = 0.32). Potential area for home garden development was highest in large gardens (41%) followed by medium (16%) and small (9%). Out of total 480 species, richness was highest in ornamentals (46%) followed by vegetables (10%), fruits (8%), shade-trees (8%), medicinal-plants (6%), spices (3%) and unidentified species (20%). Among fruit trees, mango was the most dominant species and 90% of home gardens were growing a total 361 plants (young 37% and adult 63%) of 15 local varieties namely Ma Chit Su (39%), Sein Ta Lone (24%), Sein Sar Thee (20%), Yin Kwe (9%), Ma Naw Nwe (3%), Waso, Padamyar Nga Mauk, Mya Kyauk and 4 unknown varieties (1% each) and Wet Ta Kaut, Pan Swae and Pyo Ta Ngone (0.3% respectively). Three types of leaf attitude and 8 different leaf characters of mango varieties were identified. Diversity index of total species was 1.57 and 1.40 for mango varieties. It was concluded that species distribution was sufficient; however, there is remaining available space to extend home gardening in the study area. [ABSTRACT FROM AUTHOR] |
