A field study was undertaken to evaluate the comparative efficacy of zinc application through soil and foliar spray on growth and yield of wheat variety Kiran-95 at Soil Chemistry Section, Agriculture Research Institute, Tandojam during Rabi 2013-14. The experiment was laid out in three replicated randomized complete block design. The treatments comprised Control (No Zinc), Soil applied Zinc 5.0 kg ha-1 at tillering stage, Soil applied Zinc 10.0 kg ha-1 at tillering stage, Soil applied Zinc 5.0 kg ha-1 at tillering + 5.0 kg ha-1 at booting stage, Foliar applied Zinc 0.2% at tillering stage, Foliar applied Zinc 0.4% at tillering and Foliar applied Zinc 0.2% at tillering stage + 0.2% at booting stage. The statistical analysis of data suggested that soil and foliar applied zinc affected significantly (P<0.05) growth and yield traits of wheat variety Kiran-95. The results illustrated that Soil applied Zinc 5.0 kg ha-1 at tillering + 5.0 kg ha-1 at booting stage produced maximum plant height (99.0 cm), tillers (410.7 m-2), spike length (13.1 cm), spikelets per spike (23.0), grains per spike (45.1), seed index (43.4 g), biological yield (9354.4 kg ha-1) and grain yield (5123.4 kg ha-1), closely followed by Foliar applied Zinc 0.2% at tillering stage + 0.2% at booting stage with 97.6 cm plant height, 408.8 tillers m-2, 13.0 cm spike length, 22.8 spikelets per spike, 45.0 grains per spike, 43.2 g seed index, 9273.4 kg ha-1 biological yield and 5080.7 kg ha-1 grain yield. The performance of wheat variety Kiran-95 ranked 3rd, 4th, 5th and 6th almost in all the growth and yield parameters particularly grain yield (kg ha-1) when fertilized with Soil applied Zinc 10.0 kg ha-1 at tillering stage, Foliar applied Zinc 0.4% at tillering, Soil applied Zinc 5.0 kg ha-1 at tillering stage and Foliar applied Zinc 0.2% at tillering stage. However, minimum growth and yield traits were registered in Control (No Zinc). Furthermore, the results concluded that although numerically maximum growth and yield values were recorded in Soil applied Zinc 5.0 kg ha-1 at tillering + 5.0 kg ha-1 at booting stage but statistically the differences between Soil applied Zinc 5.0 kg ha-1 at tillering + 5.0 kg ha-1 at booting stage and Foliar applied Zinc 0.2% at tillering stage + 0.2% at booting stage were non-significant. Hence, Foliar applied Zinc 0.2% at tillering stage + 0.2% at booting stage were found the most economical treatment for obtaining optimum yield of wheat variety Kiran-95.
