Title StatementStudy on crop yield as affected by varying degree of inundation
General NoteMunoz, Nueva Ecija: CLSU, 1984. var. p. -(PCARR Proj. No. 948; Sub-proj. 3; Study 2)
Summary, Etc.The study determined the effect of excessive soil moisture on the growth and yield of crops and established drainage criteria based on plant response to varying levels of inundation during its growth. Rice varieties IR-36 and IR-54 and several upland crops were observed in four sets of experiments. Findings showed that IR-36 had significantly high mortality rate and low yield when continuously inundated in 15-20 cm deep water from transplanting to the 12th week. Growth rate was also considerably reduced when water depths ranged from 10-15 cm during the first two weeks. In the case of IR-54 plants, mortality rate was relatively low when inundation depths ranged from 0-10 cm during the first week. Growth rate increased when plants were subjected to higher water depths of 5-20 cm for the same period. However, high mortality rates were noted when water levels ranged from 10-20 cm during the first two weeks. Mungo and soybean thrived well on water depths of 15-30 cm and withstood waterlogging once or twice a week without reduction in yield. In terms of growth rate, pechay and radish had almost the same response to any water table depth while mustard grew better at 40-100 cm depth. Yield wise, pechay was not affected at all by water table location while mustard yielded best at 40-100 cm water table depth and radish yielded highest when water table was 100 cm below ground surface. In the case of sesame, yield was significantly higher for plants in areas with water 15 cm deep than for those areas where water table was 100 cm below ground surface
