Experiment Title EFFECT OF SALINITY LEVELS OF IRRIGATION WATER ON SUMMER RICE VARIETIES (micro-plot)
Research Type Departmental Research
Experiment Background Salinity is a major factor reducing plant growth and productivity of rice crop in coastal area of South Gujarat. The Coastal area of South Gujarat are seriously affected by salinity and water logging. This problem is more serious in the agriculture, which accounts for reduction in rice production are affected by salinity. Rice is the most important staple food crop in India as well as in coastal area of South Gujarat. Rice is rated as a salt sensitive crop. Although, salinity affects all stages of the growth and development of rice plant and the crop responses to salinity varies with growth stages, concentration and duration of exposure to salt. High salt concentration may lead to plant death and no yield. The effects of salinity on crop yields were indicated with a scale of conductivity with 5 steps of increasing yield restriction (0-2, 2-4, 4-8, 8-16, >16 dS/m, respectively). In the most commonly cultivated rice cvs., young seedlings were very sensitive to salinity. The grain yield is much more depressed by salt than the vegetative growth. Yield is a very complex character which comprise of many components and these yield components are related to final grain yield which are also severely affected by salinity. Panicle length and 1000-grain weight are significantly affected by salinity. In spite of these extensive studies of salinity on rice, our knowledge of the quantitative effect of salinity on rice seedling growth and yield components is limited. Keeping these views, this study was conducted to determine the effects of salt levels on rice cultivars to analyze the salt sensitivity of different yield components and to identify the most important yield components responsible for reduction in grain yield of rice crop.
