Drip Fertigation Technologies

The experiment was conducted to evaluate the growth and yield response of cauliflower (Brassica olreracea L.) under surface and subsurface drip irrigation with fertigation through field experiment. The treatment consisted of two irrigation methods viz., surface and subsurface drip irrigation. The surface drip laterals were placed on the surface whereas in subsurface drip the laterals were placed at 15 cm depth below surface. The biometric attributes viz., plant height, number of leaves, stem diameter, leaf area index and yield attributes viz., total curd yield and circumference of curd were monitored periodically. The soil moisture during irrigation cycle and root length density at harvest also was measured by taking the soil samples.
