| dc.description.abstract | The general objective of this study was to evaluate the effects of exogenous application of paclobutrazol (PBZ) and potassium nitrate (KNO3) in tomato subjected to different water regimes. Specifically, it aimed to determine the response of tomato under different water regimes as affected by application of PBZ and KNO3 and identify the optimum concentration of PBZ and KNO3 that will give highest survival of tomato in different water regimes. the treatments were: water regime as main plots (non-waterlogged, 24 hrs, and 48 hrs waterlogged) and combination of PBZ (0, 250, 500 ppm) and KNO3 (0%, 4%, 8%) as sub-plot. Treatments were arranged in split plot in RCBD. Waterlogging caused reduction in % survival of tomato; however there was no further decrease from 24 hrs to 48 hrs waterlogging. this trend was similar to plant height, number of leaves, leaf dry weight, stem dry weight, plant dry weight and days to flowering. In terms of PGRd, across WR, highest concentration of PBZ w/o KNO3 (0% KNO3 + 500 ppm PBZ) had highest % survival. However, when 500 pppm PBZ combined with 4% and 8% KNO3 there was reduction in % survival. This was also observed in number of adventitious roots wherein 8% KNO3 + 500 ppm PBZ, had the lowest number of adventitious roots. Plants treated with PBZ and KNO3 were able to maintain partitioning coefficient in stem when subjected to waterlogged condiction. Furthermore, there was decreasing trend in % survival at increasing KNO3 in different water regimes. | |
