| Abstract:
The influence of solar radiation interception on the physical characteristics of fruits of guava cv. Sardar under 3 different spacings (6×4 m, 6×5 m and 6×6 m) was studied in the Department of Horticulture at Punjab Agricultural University, Ludhiana during 2001 - 02. Trees spaced at 6×6 m intercepted significantly higher radiation on per tree basis than 6×5 m and 6×4 m spaced trees. The upper part of tree canopy intercepted maximum radiation than the middle and lower canopy parts irrespective of planting distances. The size and weight of fruits harvested from the trees spaced at 6×6 m were found significantly higher than the trees spaced at 6×5 m and 6×4 m. However, the specific gravity of the fruits harvested from 6×4 m were found maximum and it decreased with increase in spacing. The fruit yield/tree decreased with decrease in spacing. | |
