Role of nitrogen, phosphorus and potassium on quality of onion seed cv. Akola Safed

The research work was carried out at Main Garden, Department of Horticulture, Dr. PDKV, Akola, and Maharashtra in 2015-16 and 2016-17 to study the role of nitrogen, phosphorus and potassium on quality of onion seed cv. Akola Safed. Three different factors were considered, in which first factor (N) nitrogen with levels (0, 100, 150kg/ha), (P) phosphorus with levels (0, 50, 75kg/ha) and (K) potassium with levels (0, 50, 75kg/ha). The experiment consisting of 27 treatments combination was laid out in factorial randomized block design (FRBD) with three replications. The results showed that, the quality of seed of onion in respect to test weight (g), germination per cent (%) and graded seed yield were significantly influenced by different treatment combination. The quality of onion seed increased with increased levels (i.e. NPK at 150:75:75kg/ha) of different treatment combinations. Whereas, the seed yield per hectare was increased with combine application of nitrogen at 150kg/ha, phosphorus at 75kg/ha and potassium at 50kg/ha.
