| dc.description.abstract | The present investigation entitled “Integrated nutrient management studies in guava (Psidium guajava L.) cv. Hisar Surkha” was carried out at experimental orchard, Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2017-18 and 2018-19. Integrated soil application of biofertilizers consisted of Azotobacter and PSB in combination with vermicompost and FYM applied with 50%, 75% and 100% RDF in a RBD with three replications by taking one replication per plant on 4-year-old guava plants. 100% RDF + vermicompost + Azotobacter + PSB proved most effective in improving growth parameters namely tree height, trunk girth, tree volume, fruit set, fruit retention and yield parameters viz. average fruit weight, number of fruits per tree and fruit yield per tree which was found at par with 100% RDF + FYM + Azotobacter + PSB. Number of seeds per fruit and weight of seeds per fruit was not significantly affected by different treatments. However, fruit quality parameters specifically TSS, acidity, TSS:Acid ratio, vitamin C content, pectin content, total sugars, reducing sugars and non-reducing sugars were improved with 100% RDF + vermicompost + Azotobacter + PSB. Shelf life of fruits increased with integrated use of 100% RDF with vermicompost and biofertilizers. Similarly, improved leaf N and P content; soil N, P content along with soil microbial biomass in terms of Azotobacter and PSB population was found with 100% RDF + vermicompost + Azotobacter + PSB. However, no significant effect was observed on leaf micronutrient content (Zn, Fe, Cu and Mn), soil pH, EC, organic carbon and available K. | en_US |
