Abstract
Field experiments were carried out during kuruvai (July,2019) and Navarai (March,2020) to study the influence of zinc and silicon through fly ash along with silicate solublizing bacteria on yields, NPKSi uptake and economics of rice. The treatments comprised of T1-RDF, T2- T1 + 25 kg ZnSo4 ha-1, T3- T2 + 50 kg Si ha-1, T4 - T2 + 100 kg Si ha-1, T5 – T2 + 150 kg Si ha-1, T6 – T2 + Silicate Solublizing Bacteria, T7 – T3 + Silicate Solublizing Bacteria, T8 – T4 + Silicate Solublizing Bacteria and T9 – T5 + Silicate Solublizing Bacteria. The experiments were laidout in randomized block design and replicated thrice. Among the various treatments tried, T9 (25 kg ZnSo4 ha-1 +150 kg Si ha-1+ Silicate Solublizing Bacteria) recorded higher yields (grain and straw), NPKSi uptake and economics of rice. The treatment T8 (25 kg ZnSo4 ha-1 +100 kg Si ha-1+ Silicate Solublizing Bacteria) was next order. Based on two season experiment, it concluded that rice applied with RDF + 25 kg ZnSo4 ha-1 +150 kg Si ha-1+ Silicate Solublizing Bacteria is economically viable practice to enhance the productivity, NPKSi uptake and profitability of rice.
