Effect of NPK along with FYM and Poultry manures on growth, flowering and fruiting of four year old sweet orange (Citrus sinensis L.)

Abstract

The experiment entitle “Effect of N. P. K. along with FYM and Poultry manures on growth, flowering and fruiting of four year old sweet orange (Citrus sinensis L.)” was carried out at the fruit research farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad (U.P.) - 211007. The observations were recorded on growth parameters viz, plant height (cm), number of leaves/plant, number of branches/plant, stem diameter (cm), plant spread (cm2), leaf area (cm2), length of inter-nodes (cm), no. of flower/plant, no. of fruit/plant and incidence of disease percentage. The experiment was laid out with 13 treatments having different combination of N. P. K. along with FYM and Poultry manures in Randomized block design with three replications. The observations recorded during the course of investigation were subjected to statistical analysis as per method of ‘Analysis of variance’ (Fisher, 1950). Considering the present investigation it is concluded that the treatment (T12) RDF (25%) + FYM (25%) + Poultry Manure (50%) was found the best in terms of maximum plant height (380 cm), number of branches (22), number of leaves/plant (597.67), stem diameter (2.59 cm), plant spread (177 cm), leaf area (46.33 cm2), length of inter-nodes (13.33 cm), number of flowers/plant (243), number of fruits/plant (86.67), with minimum incidence of disease percentage (0.33%).
