Abstract:
A field experiment was conducted during rabi, 2017-18 on loamy sand soil at Agronomy Instructional Farm, C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to evaluate the effect of variety, chemical fertilizer and bio-fertilizers on growth and yield of cumin. Twelve treatment combinations comprising of two varieties (GC 3 and GC 4), two levels of fertilizer (100% and 50% RDF) and three levels of biofertilizers (Azotobacter + PSB, Azospirillum + PSB and NPK consortium) were laid out in randomized block design (factorial) with four replications. Significantly higher volatile oil content, net return and B:C ratio were found when cumin variety GC 4 was fertilized with 100% RDF (40:15:00 NPK kg/ha) and inoculated with Azospirillum + PSB. Higher microbial status of soil was found significantly higher under variety GC 4, 50% RDF and seeds inoculated with Azospirillum+ PSB.
