Impact of biofertilizer and irrigation in enhancing productivity potential of linseed (Linum usitatissimum L.) under utera condition
Year: 2015
Type: article
Abstract: A field experiment was conducted during rabi 2012-13 and 2013-14 at Agricultural ResearchInstitute, Patna, Bihar to study the effect of biofertilizer viz., Phosphate Solubilising Bacteria,Azotobacter and irrigation in enhancing productivity potential of linseed (Linum usitatissimum L.)under utera condition. Utera linseed responded significantly to the irrigation treatments with highestyield recorded under two irrigations, where as the percentage increase in yield was found higherfor one irrigation over no irrigation. All the fertility treatments showed significant increase inseed yield with respect to control during both the years. The treatment, 100% recommended doseof nitrogen and seed inoculation with PSB and Azotobacter significantly out yielded othertreatments during both the year of experimentation. The interaction effect also revealed significantincrease in seed yield with respect to irrigation and fertility, with highest yield of 1074 kg/ha and844 kg/ha recorded under two irrigations along with application of 100% RDN + PSB andAzotobacter during 2012-13 and 2013-14 respectively. The percentage increase in yield by 100%RDN + PSB and Azotobacter, over the control fertility treatments, was found higher when appliedwith one irrigation with values of 132% and 113% during 2012-13 and 2013-14 respectively. Thehighest net return and B:C ratio was recorded for two irrigations with 100% RDN + PSB andAzotobacter, followed by one irrigation with 100% RDN + PSB and Azotobacter.
