| Abstract:
An attempt has been made to understand the yield forecasting of guava based on different parameters. Forecasting yield in any perennial crop involves two different aspects of estimation viz., the sampling and forecasting of individual tree yield as well as the whole orchard yields. In the present study, Allahabad Safeda and Sardar were subjected to uniformity trial analysis. Data on tree height, canopy spread, fruit number and fruit weight for 100 trees each in Allahabad Safeda and Sardar were compiled for four consecutive years. In the present investigation, it was found that yield could be predicted with the help of fruit number and fruit weight by selecting an optimum sample size of 35 for each character for cultivar Allahabad Safeda and 39, 38 in Sardar at 95 per cent confidence probability, respectively for the above characters, with condition that the sample mean falls within 5 per cent of the actual value. | |
