ABSTRACT

Fertilizer application from integrated organic and inorganic sources is universally accepted agronomic practice for improved yield and soil properties. However, determination of a suitable dose from either source that could beneficially and easily combine to give maximum output still needs lots of research. The experiment was conducted during wheat season 2014-15 on a selected water eroded site in District Swabi. Fourteen treatments viz the control (T1), recommended dose (RD) (120:90:60 kg ha-1 N: P2O5: K2O. T2), four combinations of farmyard manure (FYM) i.e 20, 15, 10 and 5 t ha-1 with 0, 25, 50, 75% of the RD (T3, T4, T5, T6, respectively), four combinations of poultry manure (PM) i.e. 10, 7.5, 5 and 2.5 t ha-1 with 0, 25, 50, 75% of the RD (T7, T8, T9, T10, respectively) and four combinations of the mixed FYM (5 t ha-1) and PM (2.5 t ha-1) with 0, 25, 50, 75% of the RD (T11, T12, T13, T14, respectively) were evaluated in RCB design. Results revealed that T13 (integrated 5 t ha-1 FYM + 2.5 t ha-1 PM + 50% RD) resulted in the maximum grain and biological yield (4.2 and 11.2 t ha-1, respectively) and 1000 grain weight (40.57 g). Furthermore, T3 (20 t ha-1 FYM+0 NPK) resulted in the highest organic matter (1.42%) in soil as well as reduced soil pH and bulk density over control whilst the maximum soil mineral N, P and K (27.2, 15.4 and 136 mg kg-1, respectively) were recorded in soil treated with 10 t ha-1 PM alone. However, due to highest yield as well as improved soil properties, this research suggest the integrated use of FYM+PM (5 + 2.5 t ha-1) + NPK 50% of the recommended dose for sustainably improved production on eroded soils.
