16
Q

refers to the number of plants per unit area

A

population density

17
Q

important to know for planning purposes; e.g. how much or how many planting materials will be needed

A

population density

18
Q

BENEFITS OF OPTIMUM POPULATION DENSITY

A
  1. Early build up of sufficient leaf area index for optimum use of solar energy
  2. Early and better control of weeds
  3. Increase efficiency in use of land, light and water
19
Q

PLANTING DENSITY DEPENDS ON:

A
  1. crop species
  2. soil fertility and soil mgt practices
  3. season (availability of water and solar radiation)
  4. method of propagation used
  5. mechanization to be employed
  6. cropping system to be adopted
20
Q

optimum population density therefore varies with plant height, canopy shape and size, growth habit, horizontal spread of root system

TRUE OR FALSE

A

TRUE

21
Q

adopt lower population density in _____ soils and during _____ season

A

fertile; rainy

22
Q

adopt higher planting density for ______ plants

grafted or direct seeded

A

grafted

23
Q

POPULATION DENSITY COMPUTATION

hill method

A

PD= area (m^2) x no. of plants per hill
__________________________________
S1 x S2

24
Q

POPULATION DENSITY COMPUTATION

drill method

A

PD= area x no. of plant per linear meter
__________________________________
distance between rows

25
Q

for perennial crops, planting density varies with
planting pattern

A
  1. square system
  2. triangular system (hexagonal)
  3. quincunx system (diagonal
26
Q

PERENNIAL CROPS PLANTING DENSITY

plants are placed at the corners of the square; plants are equidistant with one another

A

square system

27
Q

PERENNIAL CROPS PLANTING DENSITY

plants are set at the corners of triangle (equilateral); allows higher PD than the square by 15 %.

A

triangular system (hexagonal)

28
Q

PERENNIAL CROPS PLANTING DENSITY

a modification of the square system where an additional plant is planted at the center of each square; has higher PD than the first 2 systems

A

quincunx system (diagonal)

29
Q

PERENNIAL CROPS PLANTING DENSITY COMPUTATION

square system

A

no. of plants = Area / s^2

30
Q

PERENNIAL CROPS PLANTING DENSITY COMPUTATION

triangular system (hexagonal)

A

no. of plants = Area / s^2 X1.15

31
Q

PERENNIAL CROPS PLANTING DENSITY COMPUTATION

quincunx (diagonal)

A

= Area (m2)/s^2 + [ (L/S-1) (W/S-1)]

32
Q

plants are planted following the contour line in hilly/slopy areas

A

contour system

33
Q

PLANTING OPERATIONS IN COUNTOUR SYSTEM

A
  1. time of planting
  2. transplanting perennials
34
Q

biennial plants like sugarcane and pineapple produce suckers which will serve as the next crop; these new plants are called ________

letting these suckers grow to serve as the next
crop is called _________

A

ratoons, ratooning
