Where U N
and U 0
are total plant N uptake
(kgha -1 ) in the above ground biomass at a certain
level of fertilizer application [F (kg ha -1 )] and in the
control treatment, respectively.
The mean uptake of nitrogen, phosphorus
and potassium by was 64.91, 22.34 and 38.1 kg
ha -1 , respectively (Table 1). Nutrient (NPK) uptake
was influenced by different cultivars. Variety V 2
(NIDW 295) and V 3
(UAS 415) registered similar
nitrogen, phosphorus and potassium uptake but
significantly higher in comparison to other varieties
viz., V 1
(Sonalika), V 4
(NIAW 917) and V 5
(DWR 162)
owing higher yield. Among the latter varieties V 1
had
performed well in terms of nutrient (NPK) uptake over
V 4
and V 5
, which were on par. Variation in NPK uptake
among varieties differing in their genetic makeup was
