摘要：Experiments were conducted with the objectives to determine optimum combinations of N and P application rates on fruits quality of tomato under furrow irrigated and rain fed season. Four levels of N and P rates were factorially combined, laid on RCBD replicated three times. The experiment was conducted during cool-dry season using furrow irrigation, and the second similar experiment was conducted during the rainy season. Sample fruits were harvested at light-red ripe stage assessed for the parameters such as TSS, fruit pH, Titratable acidity (TA), juice volume, TSS/ TA ratio, fruit weight, length and diameter and subjected to analysis of variance using SAS. The results indicated that application of N and P fertilizers under different production conditions affected most fruit quality characteristics. Higher average TSS and pH were recorded from furrow irrigated tomato cultivated during dry seasons; while lower TSS and pH was recorded from under rain fed growing. These studies showed that there is the possibility of achieving desired level of fruit quality such as TSS and pH under defined N and P application rates and production conditions which is important for use in tomato processing. Thus future research should confirm these findings.
