Application of different organic manures in optimizing optimum yield for wheat in calcareous soil

A field experiment was conducted during winter season of 2014-2015 at a farm field located in Swabi Khyber Pakhtunkhwa, Pakistan with the main aim to evaluate the influence of different organic manures on wheat (Triticum aestivum L.) production. The experiment was laid out in a randomized complete block design (RCBD), with four replications. The treatments were: T1 (control, no manure), T2 (Cattle manure), T3 (Poultry manure) and T4 (Sheep manure). All the organic manures were applied at the rate of 10 t ha-1. At maturity, plant height (cm), number of grains per spike, grain yield and biological yield were recorded. Results led to the conclusion that T3 (poultry manure) gave the best results, as compared to other treatments. The values of plant height, biological yield and grain yield were 87 cm, 13.66 t ha-1 and 5.750 t ha-1, respectively, for poultry manure treatment. Results for number of grains per spike and 1000-grain weight were found non-significant in the prevailing soil condition
