Effect of boron, calcium nitrate and NAA on initial seed quality of chilli

An experiment was conducted to study the effect of seed treatment with boron, calcium nitrate and growth regulator (NAA) on germination and growth parameter of chilli cultivar Varada (GCS-94-68) during 2015–2016 at Seed Testing Laboratory, Seed Unit, University of Horticulture Sciences, Bagalkot. The experiment was laid out complete randomized design comparing with seven treatments viz NAA (25 and 50 ppm), boron (3 and 4 ppm), calcium nitrate (1 and 2 gm/lit of water) and absolute untreated control. The results revealed that boron (3 ppm) recorded significantly highest initial seed germination (86.33%) over control (61%) and on par with all other treatments. Seeds treated with boron (3 ppm) were shown highest seedling length and vigor Index (7.13 and 612.62 respectively) over untreated control (3.96 and 242.07 respectively).
