摘要

The need of determining a standard size and shape for an experimental plot of major crops in different area of the Khyber-Pakhtunkhwa, under different climatic conditions like irrigated or rainfed. The experiment on size and shape of plot with wheat variety Pirsabak-2004 was conducted in Agriculture Research Institute Tarnab, Peshawar during the year 2014-15. The land under experiment trial was under wheat rotation in previous year, and all operation like cultural manuring etc. were uniformly applied. The co-efficient of variation for the most feasible ratio of length to width (i.e. 2.50) in the experimental plot was found to be 23.95%. The long and narrow plots are more efficient as compared to shorter and wider plots of the same size. Based upon theoretical numbering of replications in order to bring down C.V to 5%, the suitable number of replication in case of plot size (3.05 m × 1.22 m) was found between 2 to 6. The fertility trend moves gradually from West to East, as compared to the North to East. The South-Western side also gave the high rate of fertility, based on the study of plot size of (3.05 m × 1.22 m) which was found most suitable for experimental purpose.
