Economical Evaluation of Transplanting and Seed Hydropriming in Comparison with Conventional Planting in Grain Maize: A case study in Alborz province

One of the effective factors in improving water use productivity and shortening the time required to complete plant growth is proper agricultural management practices such as changing planting methods In this research, in order to investigating of economic evaluation of seedling and hydropriming cultivation methods in comparison with conventional cultivation of corn seeds, this study was carried out as split plot factorial experiment based on randomized complete block design with three replications at Seed and Plant Improvement Institute (SPII) in 2017 and 2018. The experiment included four planting dates (1 July, 10 July, 20 July, 1 August) in main plot, three planting methods (seed planting, seed hydropriming, transplanting) and two hybrids (KSC 260 and KSC 704) as factorial in sub plots. In this research, for economic analysis used Partial budgeting Method, benefit and cost analysis, marginal net benefit of treatments and the percent of sale return. According to the results, the mean of yield in seed planting treatment and with KSC 704 cultivar under planting date until 20 July was 12245.7 kg/ha during experiment years. Means of net income of seed planting treatment with KSC 704 cultivar under planting date until 20 July was estimated 123.6 Iranian million rial /ha. Sale return of grain maize in this treatment was estimated %70.2, that is more than treatment. Thus, seed planting with 704 cultivar in planting date 20 July as the first priority suggested in target region.
