Abstract:
The present investigation entitled, “Effect of integrated nutrient managemnt on growth and yield of guava (Psidium guajava L.) cv. Allahabad Safeda under high density planting” was conducted at Department of Horticulture, Allahabad School of Agriculture, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad during 2016-17 and 2017-18. The experiment laid out in Randomized Block Design (RBD) with three replications. The experiment consisted of ten treatments viz. (T0) 100% RDF (NPK-180,90,90g), (T1) 75% RDF+2.5 kg Vermicompost, (T2) 50% RDF+2.5 kg Vermicompost, (T3) 75% RDF+10 kg FYM, (T4) 50% RDF+10 kg FYM, (T5) T3 + Micronutrients (Zn+B+Mn (0.5,0.2,0.1%), (T6) T4 + Micronutrients (Zn+B+Mn (0.5,0.2,0.1%), (T7) 50% RDF+10 kg FYM+Azotobactor, (T8) 50% RDF+10 kg FYM+ Azotobactor+ PSB (100g/P), (T9) 50% RDF+10 kg FYM+ VAM, (T10) 50% RDF+10 kg FYM+ Azotobactor+ VAM. The results revealed that the application of 75% RDF+10 kg FYM + Micronutrients (Zn+B+Mn (0.5,0.2,0.1%), (T5) significantly influence the growth and yield of guava. Maximum plant height (256.80 cm), more number of branch (20.56), maximum number of leaves (150.16), maximum plant girth (2.58), higher number of flowers (79.33), more number of fruits (38.23), fruit diameter (6.51 cm), fruit length (6.05 cm) at harvest, fruit volume (121.75 ml), average fruit weight (152.84 g) and number of fruits per plant (5829.59 g) were obtained with treatment T5. The combined application of 75% recommended dose of NPK with FYM (10 kg) and micronutrient gave significantly higher fruit yield per hectare (99.56q/ha).
