Response of boron and lime application on growth and seedyield of snowball cauliflower (Brassica oleracea var.botrytisL.)cv.PSBK-1

Abstract

In order to study the effect of lime and boron in different combinations as soil, soil +foliar and foliar application on the growth dynamics and seed yield performance of snowball cauliflowerPSBK-1, a field experiment was conducted duringRabi season of 2008-09 under rainfed mid hill conditionof Uttarakhand. It was found that application of lime and borax as basal @ 500 kg/ha and 5.0 kg/hafollowed by foliar spray of boron @ 0.25% at 40,60,80 DAT was the best treatment for maximumnumber of leaves per plant (16.13), number of primary branches per plant (12.53), seed yield per plant(28.31g) and seed yield per hectare (7.96q) whereas, application lime and borax as basal @ 500 kg/ha and5.0 kg/ha followed by foliar spray of boron @ 0.50% at 40,60,80 DAT was second superior treatmentfor highest plant height (92.06 cm), siliqua per plant (1100.11), siliqua length (6.14cm), seeds per siliqua(20.34) and at par with seed yield per hectare (7.65q) in cauliflower cv. Pusa Snowball K-1 in rainfed midhill conditions of Uttarakhand.
