Abstract:

A field experiment “Effect of nano zinc and silicon on performance of wetland paddy (Oryza sativa L.)” has been conducted in Kharif (2019-20) at AHRS, Bavikere, UAHS, Shivamogga to see the effect of nano zinc and silicon on growth and yield of rice. The experiment consisted 12 treatments viz., seed treatment and foliar application of nano zinc and nano silicon either alone or in combination (T1- T6), foliar application EDTA ZnSO4 (0.5%) at 40 DAT (T7), foliar application of potassium silicate (0.5%) at 40 DAT (T8), foliar application EDTA ZnSO4 (0.5%) at 40 DAT + Potassium silicate (0.5%) at 40 DAT (T9), soil application of ZnSO4 @ 25 kg ha -1 (T10), rice hull ash @ 2 t ha -1 + RDF (T11) and control (T12) replicated thrice was laid out in completely randomized block design. Application of both zinc and silicon (T6) in nano form as foliar @ 40 ppm each at 40 DAT registered significantly higher No. of leaves, leaf area index, leaf area duration, total dry matter, crop growth rate , grain yield (6034 kg ha-1) and straw yield (6693 kg ha-1) closely followed by foliar application of nano zinc alone @ 40 ppm at 40 DAT.
