Definition Optimal Values Of Device Parameters That Semi-Open Pomegranate Trees
Abstract
The parameters of the device for semi-opening pomegranate bushes, ie the
transverse distance between its bodies, the transverse distance between the lemexes, their
angle of entry into the soil and the degree of opening of pomegranate bushes at the speed of
aggregate movement, heights of unevenness between rows and soil quality The results of
multivariate experimental studies to determine the optimal values that provide low energy
consumption are presented. Multivariate experiments were conducted according to the
Hartley-4 plan. The evaluation criteria were the degree of opening of the pomegranate
bushes, the height of the irregularities on the surface between the rows, the degree of soil
compaction, ie the amount of soil fractions smaller than 50 mm, and the traction resistance of
the device. The data obtained in the experiments were processed by the program
"PLANEXP" developed in the experimental department of SRIMA and obtained regression
equations that adequately represent the evaluation criteria. The Cochrane criterion was used
to assess the homogeneity of the variance, the Student's criterion was used to assess the value
of the regression coefficients, and the Fisher criterion was used to assess the adequacy of the
regression models. The obtained regression equations are solved together with the conditions
that the degree of opening of pomegranate bushes is not less than 50%, the height of the
irregularities on the surface of the row is not more than 15 cm, the amount of soil fractions
less than 50 mm is not less than 75%. values are determined.
