Effect of levels of FYM, fertilizers and Bio-fertilizers on quality of onion (Allium cepa L.) cv. N-53

The “Effect of levels of FYM, fertilizers and biofertilizers on quality attributes of onion (Allium cepaL.) cv. N-53” in sandyloam soils. The experiment comprising of 27 treatment combinations and replicated three times, was laid out in Factorial RBD with three fertility levels (0, 50 and 100% of recommended dose of NPK), three treatments of organic manure (control, FYM @ 20 t ha-1 and FYM @ 10 t ha-1) and three bio-fertilizers (No inoculation, PSB inoculation and Azospirillum inoculation) were applied in the plots. The results of the study have clearly shown that highest TSS and Ally- propyl- disulphide were observed in FYM @ 20 t-1 followed by inorganic fertilizers @ 100% RDF and Azospirillum. While the lowest content of TSS and Ally- propyl- disulphide in onion bulb were observed in control (M0) followed by no inoculation (B0) and control(F0). In arid region, the soil nature is sandy loam and it’s deficient in nutrient content. So, increasing application level of manure, fertilizer and bio-fertilizer responds to crops for its quality. Further it may be concluded that application of 20 t ha-1 FYM and 100% RD of NPK is worth recommendable for farmers of arid region to make better quality of onion in nutrient deficient soil of arid region.
