A field experiment, carried out from winter 2001-02 to rainy season 2003 at Navgaon (Alwar) on sandy loam soil revealed that application of 60 kg P20$ha significantly improved the growth and yield attributes as well as grain (43.95 qlha) and straw yield (68.61 qlha), harvest index (39.13%), protein content (10.72%) and P uptake (40.92 kglha) by wheat [Tn'ticum aestivum (L.) emend. Fiori & Paol.] over no-use of P (control), while Zn uptake increased only up to 30 kg P205/ha and thereafter decreased significantly. Agronomic efficiency decreased up to 90 kg P20$ha. Recovery of P was higher at 60 kg P205/ha (21.63%) and thereafter decreased sharply. Similarly, application of 6 kg Znlha significantly increased all the growth and yield attributes (except test weight), protein content and Zn uptake by wheat over no-use of Zn (control). Application of graded levels of zinc up to 9 kg Znlha, remained at par with12 kg Znlha, significantly increased Zn uptake by wheat crop over other levels. Application of 6 kg Znlha increased the grain and straw yields by 19.4 and 16.8% over the no-use of Zn (control). Agronomic efficiency (1 15.3 kglkg) and apparent Zn recovery (1.87%) were also higher at 6 kg Znlha. Available P status of soil increased and Zn status decreased significantly with the increase in phosphorus level up to 90 kg P20$ha. However, P status decreased and Zn status increased significantly with the increase in zinc level up to 12 kg Znl ha. Application of 60 kg P,O$ha and 6-9 kg Znlha to wheat significantly improved the growth and yield attributes, yield, protein content and P uptake in succeeding pearl millet [Pennisetum glaucum (L.) R. Br. emend. Stuntz] over control, while application of P @ 90 kg P205/ha decreased Zn and zinc @ 12 kg Znlha improved Zn uptake by pearl millet significantly over lower levels.References
