A study was conducted to test the root parameters of Bhendi under saline environment. Roots are the directly affected parts of crop, which has intimate contact with surrounding saline environment. Effect of different irrigation frequency and varied quantity of saline water on root distribution of bhendi crop was studied. The highest tap root length of 30.4 cm was recorded in F3Q3 treatment. Increased wetted depth of once in three days irrigation increased the length of tap root in F3Q3 treatment largest root spread diameter of 42.3 cm and highest number of roots 40 were observed in twice a day irrigation with 140 per cent CWN (F4Q3). Higher diameter of root spread and more number of roots help to absorb more water and nutrients for plant growth. Hence drip irrigation of twice a day with 140 per cent CWN was found to be the best combination of frequency and quantity of irrigation as it is maintaining lower salinity in the root zone for better root development which directly affects the growth and yield parameters of bhendi crop.
