Growing Tips Orange Nagpur Plant:-

Citrus species grow in tropical and subtropical humid regions. pH should be between 5.5 and 6.5. If acidity is high, it is necessary to apply lime to achieve the optimum level.

While planting care should be taken to see that the bud joint should always be above the ground level.
Temperature ranging from 10-30℃ is suitable for the cultivation of the crop.
The bearing trees require little or no pruning. All diseased, injured, and drooping branches and deadwood are to be removed periodically.
Check the top 2-inch layer of soil for dryness before watering. On windy and hot days, it requires more frequent watering.
Micro-nutrients (zinc, copper, manganese, iron, boron, and molybdenum) are required in ample quantities. It should be supplied through a foliar spray.
Application of organic mulch surrounds the basin, improves the fruit quality, and maintains a moist environment.
Fruit drop in orange can be controlled in the early stages of fruit development by applying two sprays of growth regulators- 2,4 D (15 ppm.) or GA3 (15 ppm) along with Benomyl (1000 ppm.) and urea (1%) at the time of flowering and after the fruit set.
Never prune the plants during monsoon and wet climates.
