Verification on the effect of row spacing and irrigation frequency in the performance of flue-cured tobacco at different times of planting
1985
Retales, R.O. | Simeon, M.D. | Mosura, E.F.
The time of planting affected almost all parameter except grade index and crop value. Early planting produced plants with the most number of harvested leaves (30), highest yield (3.1t/ha) and highest reducing sugar content (23.6%). Longest (62.8 cm), and thickest leaves (1.88 mg/cm2) were obtained from plants planted in December while the broadest leaves (23.9 cm) and highest nicotine content (0.69%) were obtained from plants set in January. Plants set at closer spacing (80 cm) produced higher yield (2.94t/ha) and crop value (35,522 pesos/ha). Irrigation frequency did not show any pronounced effect on the different plant characteristics measured. Row spacing and irrigation frequency interaction significantly affected nicotine content.
