Path Co~-efficient Analysis

A path co-efficient is simply a standar-
dised partial regression co-efficient & as suah,
measures the direct influence of one variable
upon another and permits the seperation of co-
rrelation co-efficient into Components of dire-
ct and indirect effect. PR

The path co-efficient in these particu-

lar instances were obtained by simul taneous

solution of following equations which express

the basic relationship between co-rrelation &

Co-efficients.

1. r15=P15 +r12 P25 +rl3 P35+ r1d P45

2., T25=P25 +rl12 P15+ r23 P35 + r24 P45

3. r35=P35 +r13 P15 +r23 P25 + r34 P45

4., r45 =P45 + r14 P15 + 124 P25 + r34 P35

2P25.r24.P45 + 2P35.1r34.P45.

Thus,the effect of climatic temperature,
relative humidity, rainfall and periocd of Sun-
Shine, directly and indirectly, through each of
these factors, have been calculated. The 'X?
variable consists of residual factors that in-
fluenced Cestrus and in this case it includes
