Effect of integrated nutrient management on growth and yield of Guava (Psidium guajava L.) under high density planting

Abstract

A field investigation was conducted at Horticulture farm, Department of Horticulture, Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur during June, 2024 to January, 2025. The eighteen treatment combinations of FYM, vermicompost, poultry manure and neem cake were evaluated with three replications under randomized block design. The results exhibited significant effect of various treatment combinations on growth and yield parameters of guava during investigation. Among the treatment combinations, T6 - 25 % RDN by Urea+ 50 % RDN by FYM + 25 RDN by Poultry Manure was recorded growth parameters, yield attributing characters viz., tree height (4.53 m), trunk diameter (71.88 cm), plant spread (4.09 m) (EW) and (3.33 m) (N-S), canopy volume (8.10 m3), number of fruit per tree (160), fruit weight (202.50 g), fruit yield par tree (32.44 kg) etc. compared to all other treatment during investigation.
