These taste buds let your brain know when something is sour
Citrus hystrix, called the kaffir lime or makrut lime is a citrus fruit native to tropical Southeast Asia and southern China.
Its fruit and leaves are used in Southeast Asian cuisine and its essential oil is used in perfumery. Its rind and crushed leaves emit an intense citrus fragrance.
“Kaffir” is thought to ultimately derive from the Arabic kafir, meaning infidel, though the mechanism by which it came to be applied to the lime is uncertain. Following the takeover of the Swahili coast, Muslims used the term to refer to the non-Muslim indigenous Africans, who were increasingly abducted for the Indian Ocean slave trade, which reached a height in the fifteenth and sixteenth century
For each completed year of growth till 5 years, 20 kg Farm Yard Manure, 100 g urea, and 1 kg Superphosphate be applied per plant in two equal split doses in June and December every year. Fifth-year onwards application of 40 kg FYM, 400 g N + 200 g P + 400 g K per plant in two split doses in June-July and September-October be applied. In addition, 150 g N be applied per plant 15 days after fruit set. Manures and fertilizers are applied in a circular trench 20-30 cm deep about a meter wide around the periphery of the tree. Manures are thoroughly mixed with soil, and the tree irrigated profusely.
Lemons are ready to pick as soon as they are yellow or yellow-green in appearance and firm. The fruit will be 2 to 3 inches in size. It’s better to wait until they are the right size and not worry so much about color than to wait for them to be completely yellow. Lemons that are ready to be picked also have a slightly glossy appearance. Lemon picking is better too early than too late. If lemons are greenish-yellow, they will more than likely ripen off of the tree. If they are squishy, you’ve waited too long.
