Abstract

In this study, collecting of management information from about 700 wheat farms in Golestan provincewas conducted during two growing seasons of 2013-2014 and 2014-2015. In each of region, POTENTIALYIELDs, the optimum CROP MANAGEMENT and simultaneously the percentage of wheat farms out of theoptimal ranges were identified in both irrigated and rainfed conditions using BOUNDARY LINE ANALYSIS. Todo this, the information was analyzed in three parts of irrigated, high-and low-yield rainfed conditions. By plotting farm’ s yield data scatter, against management factors, highest yields in different levels ofinput or management factors were selected and a boundary function was fitted to the upper boundary ofdata points. According to the results, potential yield for irrigated, high-and low-yield rainfed wheat wereestimated equal to 6816, 5791 and 3932 kg ha-1 with a yield gap of 42, 31 and 50 percent, respectively. The optimum ranges of sowing date, seeding rate, plant density, frequency and the amount of nitrogenfertilizer applied, the amount of nitrogen applied after sowing, the amount of phosphorus (P2O5) andpotassium fertilizers (K2O) applied and irrigation frequency were determined according to the results. Consider the optimum managements, farmers in each region can shrink the yield gap and reach POTENTIALYIELD result in increasing the amount of wheat production in Golestan province.
