2. High density orcharding is the practice of
accommodating higher number of plants of
the same species per unit area by planting at
a closer spacing than that is planted under
traditional system.
3. Increased sunlight capture per unit area
Land use efficiency
Appropriate vegetative reproductive balance
of the plants.

37. Benefit cost ratio of Ultra High Density guava
orcharding for a period of 5 years is 3.1 as
compared to 2.9 traditional system
orcharding.
Net profit per year, fifth year onwards under
Ultra High Density orcharding is Rs.3.39
lakh/ha compared to Rs.1.68 lakh/ha in
traditional system
38. Keeping in view yield and gross income,
pruning of guava plants thrice a year viz.
March, May and October to 50% of shoot
length can be recommended for
maximization of income from Ultra-high
density guava orchard growing under Bihar
conditions.
Application of 60% of recommended dose
of fertilizer and irrigation at 60% PE was
found to be most suitable
