Transplanting is the transfer of seedlings from nursery beds to their permanent positions in the field.
Supplying also know as filling-in is the replacement of seeds that fail to germinate or seedling that dies.
Shading is the art of erection cover above seedlings. It also protects seedlings from harsh external environmental conditions e.g. Sun and rain drops.
Land preparation involve the application of fertilizers, soil amendments, and other materials to improve the soil’s structure and fertility. Once the land has been prepared, the sweet orange trees can be planted, and the production process can continue.
Sweet oranges prefer well-drained soils with a pH range of 6.0 to 7.0. The soil should also be fertile, with adequate levels of nitrogen, phosphorus, and potassium to support the growth and development of the trees.
The production of sweet oranges typically involves the use of two types of planting materials: seeds and vegetative cuttings. Seeds can be used to produce new sweet orange trees, but they are not commonly used in commercial production due to the long germination time and the variability of the resulting trees. Instead, most sweet orange trees are propagated through the use of vegetative cuttings, which are pieces of the sweet orange tree that are cut and planted to produce new, genetically identical trees.
The production of sweet orange involves two main cultural practices: planting and care of the trees, and harvesting of the fruit. In terms of planting and care of the trees, sweet orange trees are typically grown from seedlings or grafted onto rootstock. Once the trees reach maturity, typically after 3-4 years, they will begin to bear fruit. The sweet orange fruit is typically harvested using a combination of hand-picking and mechanical shaking of the trees. The fruit is then sorted, graded, and packed for distribution.
(i) Wilting and yellowing leaves.
(ii) Stunted growth.
(iii) Swelling or knots on the roots.
Cost price = ₦200,000
Salvage value = ₦10,000
Useful life = 10years
Annual depreciation = Cost price – Salvage value/Useful life in years
Annual depreciation= 200,000 – 10,000/10
Annual depreciation = ₦19,000
(i) Inadequate information; He may lack information on where to buy farm inputs or acquire information on new innovations and current prices of farm inputs
