Responses of guava var.
JP 1 to different training and pruning intensities were studied over 5 years.
Effects of training of 18-month-old marcotted plants were noticeable in the second year.
The yield (total fruit weight and total fruit number) was more significant under light training than medium training, as reflected in 1987 results.
The effect of three pruning intensities on guava was not detected in 1989. No significant interaction was observed 1 year after the treatment was carried out.
In 1990, plants under light pruning had significantly higher yields than those under medium or heavy pruning, both in terms of total fruit weight and total fruit number.
There was, however, no difference in the average fruit weight and percent total soluble solids.
In terms of new shoot growth heavy pruning produced the most new shoots.
Fruits developed on the new shoots at the point farthest from the point of cut.
