Impact of Azospirillum lipoferum as a biofertilizer on the productivity of maize plant

During this study, the impact of Azospirillum Lipoferum as biofertilizer on maize plants productivity was observed. For this uninoculated and inoculated seeds were planted in treatments 0 and 1 (T0 & T1) fields correspondingly, whereas nitrogen fertilizers [200 kg/ha] has been supplied to treatment 2 field (T2) and nitrogen fertilizers [100 kg/ha] together with isolated Azospirillum Lipoferum has been supplied to the fourth treatment 3 field (T3). Different stages of plant development were then monitored and compared in order to observe the effect of Azospirillum Lipoferum application. It was observed that, T1 yielded 21.84% more compared to T0 while T2 yielded 4.56% more compared to T1 as well as 27.40% more compared to T0. The T3 yielded more compared to T0, T1 and T2 e.g. 36.09%, 11.69% and 6.82% more than T0, T1 and T2 respectively (because of using 1/2 dosage of suggested fertilizer applied 100 Kgha(-1) and Azospirillum inoculum in (T2). It was concluded that it was more economical to utilize the N-fertilizers at 100 Kg/ha, and inoculating seeds of maize with Azospirillum Lipoferum can lessen the N-fertilizer load up to 50% and enhance its grain production up to 12% compared to T2 where 200 Kg/ha dose of fertilizers was used, and enhance grain production up to 36% compared to T0 that was naturally grown in the absence of Azospirillum Lipoferum or fertilizers.
