Payal Sao, J.P.Collis, S. Saravanan and V. M. Prasadthose elements essential for plant growth, which are needed, in only very small (micro)quantities. These elements are sometimes called minor elements or trace elements. Micronutrientsare now known to stimulate various physiological activities, they are essentialfor satisfactory plant growth. When these minerals elements are available to the plant inthe proper amount and balance, the results are satisfactory, growth and greater yields.The investigation was taken with the objective to find out the most suitable treatment forplant growth, yield and flower quality of Gerbera.MATERIAL AND METHODThe experiment was conducted to study the Effect of micro-nutrients on plantgrowth, yield and flower quality of Gerbera (Gerbera jamesonii) cv. Queen Rebeccawas carried out on Experimental field, Department of Horticulture, Allahabad School ofAgriculture, Sam Higginbottom Institute of Agricultural Technology and Sciences duringRabi session of 2011-2012. The treatment comprised of three different concentration ofB (0.50%, 1.00%, 1.50%), Zn (1.50%, 2.00%, 2.50%) and Fe (1.00%, 1.50%, 2.00%)sprayed at 30, 60, 90 and 120 days after transplanting and control (water spray). Theexperiment was laid out in a Randomized Block Design with 10 treatments in threereplications. The plants were planted on 20th October, 2011-12 at spacing of 30×30 cm.The observations were recorded on 9 characters viz. Plant height (cm), Number ofleaves, Plant spread (cm), Number of cut flower per hectare, Days to first flower budemergence, Flower diameter (cm), Flower stalk length (cm), Flower stalk diameter (mm),Fresh weight of flower (g). Data were statistically analyzed for the study of effect ofmicro-nutrients.RESULTS AND DISCUSSIONThe maximum plant height (29.63 cm) was recorded in Zn @1.50%, followed by B@0.50% (28.76 cm), Maximum number of leaves (33.17) was recorded in Zn @1.5%,followed by B @0.50% (32.00), The maximum plant spread (48.70cm) was recorded inZn @1.5%, followed by B @0.50% (42.50cm), The maximum Number of cut flowerper hectare (6.25 lakh ) was observed in Zn @1.50% followed by B @0.50% (6.15lakh). The minimum number of days (55.33) for flower bud initiation was recorded in Zn@1.50% followed by B @0.50% (56.00), The maximum flower diameter (11.90 cm)was recorded in Zn @1.50% followed by B @0.50% (11.70cm). The maximum stalklength (39.16cm) was recorded in Zn @1.50% followed by B @0.50% (37.91 cm). Themaximum stalk diameter (4.10mm)was recorded in Zn @1.50% followed by B @0.50%(3.10 mm). It is recorded that Zn @1.50% has maximum flower weight (10.00g) followed87
