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 growth parameters i.e. plant height (cm), dry matter accumulation (g plant super(-1)) and yield attributing character [ear head length (cm)], grain and biological yield (kg ha super(-1)) were significantly superior in T sub(12) treatment than T sub(1) to T sub(10). Maximum ear head girth was found in T sub(12) treatment but it was statistically at par with T sub(11), T sub(9), T sub(8) and T sub(6) treatments. Test weight (g) in T sub(12), T sub(11) was statistically at par and T sub(12) showed significantly higher test weight than rest of the treatments and lowest test weight was obtained in T sub(1) (8.6 g). Maximum grain yield, biological yield (4279,16292 kg ha super(-1)) were obtained in treatment T sub(12) which showed increase of 28.5 percent, 24.0 percent, 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 percent more grain yield than the control. The increase in grain yield was 28.6 percent and 3.9 percent 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. Protein content in grain was maximum in T sub(12) treatment followed by T sub(11) Treatment T sub(12) recorded highest protein yield followed by T sub(11), T sub(6) and T sub(5).
