EFFECT OF ORGANIC MANURES AND MICRONUTRIENTS ON GROWTH AND FLOWERING ATTRIBUTES OF ROSE CV. ANDHRA RED (ROSA CENTIFOLIA).

A field experiment was conducted to study the effect of organic manures and micronutrients on growth and yield of Rose cv. Andhra Red (Rosa centifolia) in Andakudi village, Papanasam Taluk, Tanjore District, Tamilnadu during 2017-2018. The experiment was conducted by using different sources of nutrients viz., farmyard manure, vermicompost and poultry manure were applied in the soil, whereas micronutrients mixture viz., ZnSO₄, FeSO₄, MnSO₄ and B @ 0.5% each were given as foliar application. It was carried out in the randomized block design with three replications comprising 14 treatments. Observation on various vegetative and flowering parameters were assessed. Among all the treatments, it was significantly increased all the vegetative and flowering parameters which recorded the highest value in plant height, number of laterals, number of leaves plant^-1, leaf area (cm₂) at 45 and 90 days after pruning, total chlorophyll content (CCI), days taken for first flowering, number of flowers plant^-1, single flower weight (g), volume of flower (ml) and flower weight plant^-1 (kg) with the application of vermicompost @ 2 Kg bush^-1 along with foliar application of micronutrient mixture (ZnSO₄ + FeSO₄ + MnSO₄ + B each @ 0.5% foliar spray) followed by poultry manure @ 10 kg bush^-1 with combination of micronutrient mixture. Hence, it could be concluded that the treatment combination of vermicompost @ 2 Kg bush^-1 along with micronutrient mixture was found to have pronounced effect on maximizing growth and profuse flowering in rose cv. Andhra red in field condition when compare to other treatments. [ABSTRACT FROM AUTHOR]
