Relative prevalence of citrus species at 6 Unions of Jaintapur Upazila in Sylhet District: The relative prevalence of citrus species found in 60 homesteads of this study area is presented in Table 1. The relative prevalence of most common species like Zara lebu, Ada Jamir, Batabi lebu, Komola, Kagzi lebu and Deshi lebu were very high while, that of less common species like Sorbati lebu, Kolombo lebu, China lebu, Malta, Satkara were found very low. Zara lebu was the most prevalent among the citrus species (97.72) followed by Ada jamir (11.86). Citrus species prevalence in number and their percentage: Citrus species richness was also more in these three unions as 14 tree species in Charikata union, 10 in Fatehpur and 10 tree species in Chicknagul union. Among the citrus species Zara Lebu was found greater (56.29%) followed by Ada Jamir (11.61%), Komola (7.92%), Kagzi (4.98%), Batabi (4.82%), Deshi (4.18%), Kurun (3.65%) and Elachi lebu (3.13%) in the Jaintiapur upazila. The profitable species of citrus on the basis of income: The study indicates more than 70 percent people opined that Zara lebu were the most profitable citrus species followed by Kagzi lebu (11.7 percent) and others species. On the other hand, ten percent farmers did not have any response about the profitable species of citrus. Zara lebu means Zara lemon the most popular and one of the costliest lemons in ethnic market i.e. price of a single lemon can reach up to 1.00 GBP (Great Britain Pound) in UK ethnic market. Price in BDT varied from 10.00-12.00 to 100.00 per piece lemon, depending on area, season, availability and size. Citrus species density: Species density means number of tree species per unit area. In this study, citrus species density was measured by number of citrus species per 100m2 homestead area. Among the 15 citrus species, average of 2.27 species per family was found in Jaintapur upazila. It was found that, citrus species density per 100m2 areas of Fatehpur, Nijpat, Charikata, Darbasta, Chicknagul and Jaintapur union under Jaintapur upazila was 0.10, 0.10, 0.16, 0.06, 0.14 & 0.12 respectively . The average citrus species density of Jaintapur upazila was 0.12 citrus species per 100 m2 homestead area. Citrus trees density: Tree density means the number trees per unit area. Here, citrus trees density was also measured by number of citrus trees per 100 m2 of homestead area. Average of 59.73 citrus trees per family was found in Jaintapur upazila. It was also found that, citrus trees density per 100 m2 homestead areas of Fatehpur, Nijpat, Charikata, Darbasta, Chicknagul and Jaintapur unions under Jaintapur upazila was 3.12, 0.32, 4.66, 0.16, 5.40 & 0.92, respectively. Average of citrus tree density was 2.43 per 100 m2 which are much higher than citrus species density 0.12/100 m2 areas. This indicates that people of this area planted several citrus trees of any single species in their homestead. The reasons for the higher citrus tree density may be the availability of seedling, sufficient homestead area, favorable environment, fertile soil and getting higher profit from certain citrus species. Tree density: Tree density means the number trees per unit area. Here, tree density was also measured by number of tree per 100 m2 homestead areas . It was found that, tree density per 100 m2 homestead. Average of tree density per 100 m2 area was 9.98.
