Effect of irrigation, fertigation and threir interactions on growth and yield of sweet orange

Abstract

The experiment on Studies on integrated nutrient and water management in sweet orange was started in the year 2010-11 for next five year up to 2015-16 under All India Coordinated Research Project on Fruits, Department of Horticulture, MPKV, at Shrirampur Dist. Ahmednagar (MS) to evaluate the combined effect of nutrient levels at different levels of irrigation.The interaction effect of irrigation and fertigation I3 F3, drip irrigation at 90% ER and fertigation with 80% of RDF recorded significantly maximum plant height (4.54 m) and canopy volume (34.87 m3) with highest number of fruits (286.49 fruits tree-1), weight of fruit (238.69 g) and yield (68.20 kg tree-1).
