Nutritional management

Manuring


• The tree should be provided with 25kg FYM/plant, at the time of planting, the fertilizer dosage should be given based on the age of the plant.
• Following are the fertilizers recommended in major guava growing states of India.

State	N (g/plant/ year)	P (g/plant/ year)	K (g/plant/ year)	FYM (kg/plant/ year)
Karnataka	300	120	150	25
Maharastra	600	300	370	12-15
Andhra Pradesh	210	160	300	60
Tamil Nadu	1000	1000	1000	50
Uttarpradesh	350	250	350	----

• Fertilizers are applied in 2 splits i.e. half of N and full of P and K during bahar treatment and remaining half of N 1-1½ month after first application.
• Foliar application of urea (3 per cent) along with Calcium, Phosphate and Muriate of Potash (Kcl) at 1 per cent could increase the yield.
• The deficiency of micronutrients such as Zn and B are rectified by spraying with Zns04 (0.3 per cent) and Boron – Boric acid (0.4 per cent) before flowering.

Bronzing (Fatio disease):


• The leaves turn to pale or purple color, small size leaves, sparse flowering, death of growing tips, ultimately plant dies.
  
• It may be due to the deficiency of NPK, Zn, Mg and low pH, spraying of 0.5 per cent DAP and Znso4 during Oct-Nov at weekly intervals.

Irrigation:


• Immediately after planting, orchard is irrigated.
• During summer and winter season orchard is irrigated at an interval of 4-6 and 10-15 days respectively
