摘要

Environmental conditions prevailing during the seasons of sowing strongly influence the processes of growth and yield determination of crops. In the humid tropics, the variations in weather conditions in the early- and late-season periods may have considerable influences on growth and yield of tomato. To describe these processes quantitatively, the effects of season of sowing on the phenology, growth and yield of early- and late-season tomato were studied in a humid zone of Nigeria. Late-season tomato gave higher fruit yield (0.57 kg/m~2) within each year but yield declined in the early-season period despite the higher crop growth rates (B). Partitioning of dry matter to fruits (P) was optimised in the late-season crop which gave a P value of 1.20 and this may be due to differences in percent fruit setting (30.6%) and high solar radiation intensity (470 MJ/m~2/day) during fruiting period. From this study, soil moisture deficits, temperatures and solar radiation are critical factors in the processes of determination of growth and yield of tomato. To realise the potentials of the different cropping opportunities in the humid tropical environments, the possible roles of agronomic practices towards the amelioration of the effects of these extreme environmental factors were highlighted.
