A Proposal of Oat Productivity Simulation by Meteorological Elements,Growth Regulator and Nitrogen

The simulation of oat grain productivity does not contemplate the use of efficient models that involve important management with meteorological elements. The objective of the study is to propose a mathematical model capable of simulating the oat grain productivity through the management of nitrogen and growth regulator with variables related to the plant and to meteorological elements. In this study, two experiments were conducted in the years of 2013, 2014 and 2015: one to quantify biomass productivity and another to determine grain productivity and lodging at the management doses of nitrogen and growth regulator. The experimental design was a randomized block with four replications in a 4 × 3 factorial scheme for 0, 200, 400 and 600 mL·ha-1 growth regulator doses and 30, 90 and 150 kg·ha-1 nitrogen doses, respectively. During the crop cycles, the meteorological variables thermal sum, radiation and rainfall were quantified. The mathematical model proposed, which combines polynomial regression of the harvest index with multiple linear regression of the biological productivity, is efficient in the simulation of oat grains productivity with the use of growth regulator, nitrogen and meteorological elements. Thus, it adds to the conventional models of simulation and becomes an aid tool for making decisions regarding the management of oats culture.

Dry Matter Accumulation, Partitioning and Re-Translocation in Two Oat Cultivars as Affected by Irrigation in the Farming-Pastoral Zone of Northeast China

To improve water management for oat production in the dry area of Jilin province, a field experiment was conducted to determine the effect of irrigation on dry matter accumulation, partitioning, re-translocation and yield. Two oat varieties, the naked "Baiyan No. 2" and the hulled "Baiyan No. 7" were subjected to three water regimes: two times irrigation, one time irrigation and no irrigation. When irrigation was applied at jointing and heading stages, the above ground biomass and re-translocation efficiency significantly increased(p < 0.05). Without irrigation, the naked oat, Baiyan No.2 had greater dry matter translocation efficiency and dry matter gain after anthesis, although grain yield did not decrease significantly. The hulled Baiyan No.7 was sensitive to water stress, with poor root development. The biomass and grain yield were significantly decreased by 51.6 and 60.5% respectively under water stress. Under conditions of west Jilin province, the naked oat, Baiyan No.2 should be preferred for dry land cultivation as it is less affected by water stress than the other cultivar. If irrigation is available both cultivars can be used but irrigation should be applied at jointing and heading stages in May or June. 1
