During rabi 2018-19 a field investigation was conducted on cauliflower (Brassica oleracea var. botrytis) cv. Pusa Snowball K-1 at the experimental farm of Department of Soil Science, COA, CSK HPKV, Palampur consisting of twelve treatments each replicated thrice in a randomized block design with an aim to evaluate the efficiency of four boron sources viz., borax, boric acid, boron metalosate and boron calcium metalosate and two methods of application i.e. soil and foliar. All treatments received recommended dose of fertilizers (120:60:75 kg/ha N:P2O5:K2O) and FYM @ 20 t/ha uniformly except farmers’ practice where FYM @ 25 t/ha was applied along with 50 per cent of recommended dose of fertilizers. Soil application of boron @ 2 kg/ha through borax and foliar spray at three levels i.e. half (0.017 %), recommended (0.034 %) and 1.5 times of recommended dose (0.051 %) with three boron sources viz., boric acid, boron metalosate and boron calcium metalosate were tested. The growth, yield co

Foliar feeding, boron supplements, cauliflower.

It can be concluded from the investigation entitled “Impact of foliar feeding of boron supplements on growth, yield contributing characters and quality of cauliflower” that foliar feeding of boron at 1.5 times of the recommended rate (0.051 %) through boron calcium metalosate along with recommended dose of fertilizers and FYM enhanced growth, yield contributing characters and quality parameters of cauliflower followed by foliar spray of boron at the same rate through boron metalosate. As metalosate products were evaluated on different crops under variable climatic situations of the country through AICRP on “Micro and Secondary Nutrients and Pollutant Elements in Soils and Plants”, the preliminary results are encouraging in terms of improved growth and quality parameters of cauliflower.
