Effects of NPK Fertigation on Leaf Nutrient Status and Yield of Citrus sinensis Osbeck cv Mosambi under High Density Planting

摘要

The field experiment was conducted during 2013-14 to study the effects of fertigation on the leaf nutrient status and yield of mosambi plant. The experiment was laid out in randomized block design with seven fertigation level, viz. T,-120% of RDF; T2-100% of RDF; T3-80% of RDF; T4-60% of RDF; T5-40% of RDF; T6-100% RDF in basal with drip irrigation and T7- 100% RDF in basal without drip irrigation and each treatment were replicated three times. Result obtained showed that the plants fertigated with 120% RDF followed by 100% RDF recorded higher leaf nitrogen, zinc, iron and boron whereas, phosphorus and potassium content was found non-significant. The same treatments were found significantly superior for yield characters and benefit: Cast ratio. Therefore, on the basis of results obtained, 120% RDFfound superior in maintaining leaf nutrient status and yield of mosambi plant under high density planting.
