Abstract

The experiment was conducted in the experimental field of Department of Horticulture, College of Agriculture, Rewa under Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur during the rabi season 2009-2010. The results showed that morphological characters of cauliflower (Brassica oleracea var botrytis L.) increased significantly with the different levels of boron and molybdenum at every stage of observation. At 60 DAT, the maximum plant height (34.35 cm), number of leaves/plant (19.45), leaf length (32.02 cm), leaf width (28.31 cm) and stem girth (5.14 cm) were recorded in treatment T₉, whereas the minimum plant height (32.50 cm), number of leaves/plant (16.49), leaf length (29.07 cm), leaf width (25.72 cm) and stem girth (4.50 cm) were observed in control treatment T₁. Yield and quality parameters were also influenced significantly due to various treatments of boron and molybdenum. The highest curd diameter (18.41 cm), fresh- weight of curd (1.24 kg), yield/ha (400.29 q) and dry matter of curd (11.37 %) were recorded in treatment T₉, whereas the lowest curd diameter (15.52 cm), fresh weight of curd (0.69 kg), yield/ha (218.28 q) and dry matter of curd (0.69 %) were found in control treatment T₁. The treatment T₉ was found significantly superior over all the treatments. The treatment T₈ registered the maximum ‘A’ grade curds (52.54%) as well as ‘B’ grade curds (35.20%) and the lowest ‘C’ grade curds (12.26%). This was equally followed by T₇ and T₉ treatments. The lowest ‘A’ grade curds 46.57% were found in case of control treatment T₁, this was followed by T₂ giving 46.64% ‘A’ grade curds, 33.09% ‘B’ grade curds and 20.01% C grade curds.
