Abstract

                                Field experiments were conducted to find out the “Effect of spacing and fertigation on yield and quality of cauliflower (Brassica oleracea L. var. botrytis)” at Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during July-November. 2011 and December, 2011- April, 2012. Tropical cauliflower hybrid Pawas using. The experiment consisted of three different spacings (60 x 60, 60 x 45 and 60 x 30 cm) and nine fertigation treatments. In fertigation, four levels of straight fertilizers (125, 100, 75 and 50 per cent of 200125125 kg NPK ha-1) and four levels of water soluble fertilizers (125, 100, 75 and 50 per cent of 200125125kg NPK ha-1) and conventional method were compared. The treatments were replicated thrice in split plot design. The results revealed that the spacing of 60 x 45 cm with the application of 100 per cent RDF through water soluble fertilizer recorded better growth, yield and quality characters in both the seasons. However higher BC ratio was recorded with the application of 75 per cent RDF through straight fertilizers at a spacing of 60 x 60 cm.

Key words : Cauliflower, Spacing, fertigation, growth, yield, quality, BC ratio.
