ABSTRACT
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, three irrigation schedules I1 ( 0.4PE), I2 (0.6PE) and I3 (0.8PE), and three fertigation levels viz. F1 (50% RDF), F2 (75%RDF) and F3 (100%RDF). The results were also compared with cauliflower under conventional surface irrigation with 1.2 IW/CPE and above three fertilizer levels. The surface drip laterals were placed on the surface whereas in subsurface drip the laterals were placed at 15 cm depth below surface and drip irrigation was scheduled at alternate day. The experimental design was split plot with three replications. The biometric attribute viz., plant height and yield attributes viz., total curd yield and circumference of curd were monitored periodically. Root length density at harvest also was measured by taking the soil samples. The results indicated that plant height, and root length density of cauliflower increased due to subsurface placement of laterals. The curd yield was higher in subsurface drip (15.27 t ha-1) as compared to surface drip (14.07 tha-1) and conventional furrow irrigation (10.98 tha-1). Among irrigation schedules the curd yields were significantly higher under I2 (0.6PE) and I3 (0.8PE) schedules than I1(0.4PE) schedules. The effect of fertilizer levels on curd yield was not significant indicating beneficial use of lower fertilizer dose of 50% RDF (60:30:30 kg ha-1; N: P2O5: K2O) through fertigation with 8, 6 and 6 splits for nitrogen, phosphorous and potassium, respectively without much reduction in the curd yield. The total water requirement of cauliflower under drip irrigation was 333.93 mm. The higher root length was obtained under subsurface drip irrigation. Hence , for cauliflower subsurface drip irrigation system should be scheduled at an alternate day with 0.6 PE depth of irrigation & 50% RDF.
