Question 11

FORMS OF DIRECT SEEDLING

seeds are uniformly distributed on the field e.g. rice, pechay, radish, leguminous cover crops

Answer 11

broadcasting

Question 12

FORMS OF DIRECT SEEDLING

seeds are sown at specified distance between hills and between rows of specified distances

Answer 12

hill method

Question 13

FORMS OF DIRECT SEEDLING

specified number of seeds are sown within rows of specified distances

Answer 13

drill method

Question 14

FORMS OF DIRECT SEEDLING

holes with no definite spacing are dug; large enough to accommodate the seeds

Answer 14

dibble

Question 15

FORMS OF DIRECT SEEDLING

seeds are put into the holes and covered with thin layer of soil

Answer 15

dibble

Question 16

refers to the number of plants per unit area

Answer 16

population density

Question 17

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

Answer 17

population density

Question 18

BENEFITS OF OPTIMUM POPULATION DENSITY

Answer 18

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

Question 19

PLANTING DENSITY DEPENDS ON:

Answer 19

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

Question 20

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

TRUE OR FALSE

Answer 20

TRUE

Question 21

adopt lower population density in _____ soils and during _____ season

Answer 21

fertile; rainy

Question 22

adopt higher planting density for ______ plants

grafted or direct seeded

Answer 22

grafted

Question 23

POPULATION DENSITY COMPUTATION

hill method

Answer 23

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

Question 24

POPULATION DENSITY COMPUTATION

drill method

Answer 24

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

Question 25

for perennial crops, planting density varies with
planting pattern

Answer 25

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

Question 26

PERENNIAL CROPS PLANTING DENSITY

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

Answer 26

square system

Question 27

PERENNIAL CROPS PLANTING DENSITY

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

Answer 27

triangular system (hexagonal)

Question 28

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

Answer 28

quincunx system (diagonal)

Question 29

PERENNIAL CROPS PLANTING DENSITY COMPUTATION

square system

Answer 29

no. of plants = Area / s^2

Question 30

PERENNIAL CROPS PLANTING DENSITY COMPUTATION

triangular system (hexagonal)

Answer 30

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

Question 31

PERENNIAL CROPS PLANTING DENSITY COMPUTATION

quincunx (diagonal)

Answer 31

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

Question 32

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

Answer 32

contour system

Question 33

Answer 33

1. time of planting
2. transplanting perennials

Question 34
