 ABSTRACT

A field experiment was conducted at Agricultural Research Station, Dharwad during kharif , 2010-2011 to study the influence of seed pre-sowing hardening with various agro-chemicals (CaCl2, CCC, KNO3, ZnSO4 and water soaking) and foliar nutrition (imposed at 70 and 90 DAS) on the yield and bio chemical traits in Bt Cotton (RCH-2) under rainfed conditions. Significant highest   yield was recorded in seed hardening @ 2%, and foliar spray @ 0.5% with CaCl2 (2276 kg/ha) followed by seed hardening treatment and foliar spray with ZnSO4 @ 0.5% (2179 kg/ha) as compared to control (1780 kg/ha).  The other yield attributing characters viz., plant height (112.7cm), days to 50 % flowering (80.2), days to 50 % boll opening (112.3), dry weight of  reproductive parts (159.6g/plant) and number of balls per plant (28.0) increased significantly with the same treatment combination. The significant increase of the bio-chemical traits viz., proline content, chlorophyll content and chlorophyll stability index in seed hardening at 2% and foliar spray at 0.5% with CaCl2 (109.29mg/g fr.wt., 2.68 mg/g fr.wt and 41.8 respectively) induced the drought tolerance thus increasing the seed yield.

Keywords: Seed hardening, Cacl2, Bt cotton, Foliar spray, proline and chlorophyll stability.
