    Effect of Integrated Nutrient Management on Growth, Yield and Quality of Guava (Psidium guajava L.) c.v. Allahabad Safeda under High Density Planting
    (Naini Agricultural Institute Department of Horticulture Sam Higginbottom University of Agriculture, Technology and Sciences Prayagraj-211007 (U.P.) 2019, 2019) GUPTA, PRATIMA; Singh, Dr. Devi
    The present investigation was carried out to study the effect of integrated nutrient management on growth, yield and quality of guava (Psidium guajava L.) cv. Allahabad Safeda under high density planting during 2016-17and 2017-18 at the Department of Horticulture, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experiment was 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 on the basis of two years study under rainy and winter season 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 (256.80cm), 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) with higher net income and B: C ratio. the Regarding fruit quality characters of fruits treatment 75% recommended dose of NPK with FYM (10 kg) and micronutrient recorded minimum acidity (0.402%), maximum total sugar (7.89 %), TSS (11.69 0Brix), ascorbic acid (237.83), and higher pectin content (1.22 %) while minimum in control. 22
