Optimal parameters of plot of land for experiments with berry crops taking into account the plants modification variability

The data were presented about variability of different biometric parameters in plants of red raspberry and black currant on the basis of which the author have revealed the minimal size and optimal form of plot of land permitting to determine the differences between variants of experiment enough for certain. The interrelation between the indices of vegetative determinants and plant productivity was estimated. It was shown that minimal size of plot for experiments with raspberry is l.0 x l.0 m, with currant - 3 x 3, 4 x 4, 4 x 3 bushes. The close positive relation was determined between variability of apical growth of currant shoots and variability of yield, between number of offshoots in raspberry and yield.
