Effect of Fertigation on Growth, Phenology and Nutrient Status in Leaves under High Density Orchard of Citrus sinensis Osbeck cv. Mosambi

Abstract

The experiment was conducted during three consecutive year i e, 2013-14, 2014-15, 2015-16 to show the effect of fertigation on phenology and vegetative growth of the plants and nutrients uptake by the leaves. Result of three years pooled data showed that increase in plant height (35.81 cm), trunk girth (4.42 mm) canopy volume (1.94 m 3 ), growth of current season shoot (9.08 cm), leaf area (31.52 cm 2 ) and leaf area index (5.54) were responses more under higher doses of fertigation i e 120 % RDF followed by 100 % RDF. The phenological observations like bud emergence period, full bloom period, fruit set, date of maturity, etc. were also affected by the doses of fertilizers. On the basis of above findings it may be concluded that the different doses of fertilizers affect on vegetative growth as well as phenological parameters of the plant.

Effect of Fertigation on Productivity and Economics of Dwarf Coconut cv. Chowghat Orange Dwarf (COD)

“…Under fertilizer management, fertigation is one of the improved and efficient methods of fertilizer application through which nutrients applied directly to root zone of the plants. By this practice fertilizer may be applied in number of split doses which increase efficiency use of water and fertilizer because this technique prevents leaching of nutrients (Karuna et al, 2019). The annual nutrient export by various parts of the palm viz., nuts, fronds, trunk, bunch and spathe reported by different workers vary from 20 to 174 kg N, 2.5 to 20 kg P and 35 to 249 kg K ha -1 (Pillai and Davis, 1963).…”
