Tillage is one of the important practices to augment yield and to aggravate the sustainability in agriculture. It is imperative to control the excessive tillage to reduce soil erosion and to shorten the cost of production. The present study was conducted in rabi season of 2013–14 at Soil Research Farm, CCSHAU, Hisar. Results revealed that grain and straw yield was found 54.10 and 73.93 q ha-1 under zero tillage, 51.75 and 72.37 q ha-1 under minimum tillage and 52.43 and 72.88 q ha-1 conventional tillage, respectively. Highest nitrogen concentration (1.81%) in wheat grain was recorded under ZT while for stover, it was observed under CT (0.36%). Amongst various P levels it increased with increasing levels of P over control in both grain and straw. Nitrogen uptake was found in grain and straw as ZT (97.92 and 25.88 kg ha-1), CT (93.33 and 26.24 kg ha-1) and MT (92.63 and 23.88 kg ha-1). Phosphorus concentration and uptake in wheat grain was highest under ZT (0.25% and 13.53 kg ha-1) followed by MT (0.23% and 11.90 kg ha-1) and CT (0.22% and 11.53 kg ha-1). In stover, P concentration was at par in various tillage practices while uptake was recorded highest under ZT treatment (6.65 kg ha-1) followed by CT (5.83 kg ha-1). Uptake and concentration of K in grain and stover indicate that the differences in concentration of K in both grain and stover were significantly at par under CT and MT whereas it was highest under ZT. Both, K concentration and uptake in grain or stover was significantly affected by application of P but significant differences were recorded only up to 60 kg P2O5 ha-1.
