Effect of micro-nutrient application on growth and seed yield of sunflower F₁ hybrid KBSH-53.

摘要

A field experiment was conducted during kharif of 2010 to study the maximization of seed yield and quality through micro-nutrient management in sunflower hybrid KBSH-53. Recommended dose of fertilizer (NPK)+gypsum at 500 kg/ha as soil application recorded highest plant height, at 60 and 90 DAS (124.28 cm and 151.91 cm respectively), while control (RDF) recorded lowest plant height at both 60 and 90 DAS (108.87 cm and 126.91 cm respectively). The yield parameters like seed yield per plant (25.47 g and 23.65 g), raw seed yield per plot (1288 kg and 1.281 kg), raw seed yield per ha (906.06 kg and 900.01 kg), graded seed yield per plot (1093.18 g and 1057.07 g), graded seed yield per ha (781.69 kg and 764.12 kg) and seed recovery percentage (86.39 and 83.93) were significantly higher with TIBA at 50 ppm and combined foliar application of boron and zinc sulfate at 0.25% at ray floret initiation stage respectively compared to control which recorded significantly lower seed yield (568.06 kg/ha).
