A field experiment was carried out during kharif season of 2012 to study the maximization in pearl millet productivity through potash, zinc and biofertilizer application. The results indicated that yield attributes i.e. total number of tillers plant[1], grain and stover yield (kg ha super(-1)) were significantly superior in T sub(12) treatment than T sub(1) to T sub(10). Maximum grain yield, stover yield (4,279,12,013 kg ha super(-1)) were obtained in treatment T sub(12) which showed increase of 28.5%, 22.4%, respectively over the control. The application of K in combination with N and P resulted in 12.6% more grain yield over the control (T sub(1)). The treatment T sub(6) receiving combined application of K, Zn, N and P exhibited 23.8% more grain yield than the control. The increase in grain yield was 28.6% and 3.9% in the T sub(12) treatment (K, Zn and Biomix was applied along with N and P) over the control and T sub(6) treatment, respectively. The T sub(3) treatment, (125 kg N + 62.5 kg P sub(2)O sub(5) ha super(-1) + 40 kg ha super(-1) K sub(2)O) resulted in Rs 5307 ha super(-1) additional net returns than the control. The treatment T6 received additional dose of Zn over T sub(3)(125 kg N + 62.5 kg P sub(2)O sub(5) ha super(-1) + 40 kg ha super(-1) K sub(2)O +25 kg ha super(-1) ZnSO sub(4)) resulted in Rs 5113 ha super(-1), Rs 10008 ha super(-1) more net returns over T sub(3) treatment and control, respectively whereas additional net returns Rs 12416 ha super(-1), Rs 2408 ha super(-1) were found in T sub(12) treatment than the control and T sub(6) treatment, respectively.
