Description The present study on potassium levels, sources and time of application on nutrient uptake
and nutrient use efficiency of onion var. ArkaKalyan was carried out at the College of
Horticulture, Bagalkot, Karnataka during Kharif season of 2015 and 2016. The uptake of
nitrogen, phosphorus, potassium and zinc recorded significantly in 200 per cent RDK
(203.62, 47.33, 236.36 kg ha-1
and 347.19 g ha-1
, respectively) over 100 per cent RDK.
Among the potassium sources, SOP recorded higher nitrogen and phosphorus, potassium
and zinc uptake (171.02 and 40.29, 197.73 kg ha-1
and 264.02 g ha-1 respectively) over
MOP. The higher nitrogen, phosphorus, potassium and zinc uptake was recorded
significantly in application of 50 per cent potassium at transplanting and 50 per cent at 30
DAT (168.52, 39.74, 195.69 kg ha-1
and 289.76 g ha-1
) over 100 per cent potassium at
transplanting (157.90, 37.03, 187.23 kg ha-1
and 277.73 g ha-1
). Significantly higher
nitrogen and phosphorus use efficiency was recorded in 200 per cent RDK (162.90 and
63.10%, respectively) over 100 per cent RDK. The higher potassium use efficiency on the
contrary was recorded in 100 per cent RDK (121.18%) over 125, 150, 175 and 200 per
cent RDK. Among the potassium sources, SOP recorded higher nitrogen, phosphorus and
potassium use efficiency of onion plant (136.82, 53.72 and 107.89%, respectively) over
MOP. The higher nitrogen, phosphorus and potassium use efficiency was recorded
significantly in application of 50 per cent potassium at transplanting and 50 per cent at 30
DAT (134.82, 52.99 and 106.68%) over 100 per cent potassium at transplanting (126.31,
49.37 and 102.0%).
