“…Developmental rates increase approximately linearly as a function of air temperature (Snyder et al, 1999), therefore the higher or lower temperature will be affected on plant growth, the exceed of the temperature above upper threshold (T U ) or lower threshold temperature (T L or T base ) will be reducing the plant growth and total yield. Now we have two constrain were used in our calculation, upper threshold temperature, was set as 30 C (Neamatollahi, Bannayan, Jahansuz, Struik, & Farid, 2012;Xiangxiang, Quanjiu, Jun, & Qiuping, 2013) and lower threshold temperature (T base ), was set as 5 C (Ash, Shaykewich, & Raddatz, 1993;Bishnoi, Singh, & Niwas, 1995).…”

At the field scale, ET a is important in irrigation planning and scheduling and is an integral part of field management decision support tools. The conventional approach of estimating actual evapotranspiration is difficult and needs more calculations and extensive data on soil-plant-atmosphere. A field experiment was conducted to simplify the measurement and calculation of actual evapotranspiration by using thermal units (heat units) for spring wheat crop under trickle irrigation system in sandy soil. Two irrigation methods were applied; the first one (A) using the crop evapotranspiration (ET c ) that depends on whether parameters, and the second (B) is the depletion from field capacity which dependent on soil parameters. Three varieties of wheat namely Sids12, Misr2 and Gemmeza10 were cultivated on sand soil and treatments arranged in complete randomized block design with three replicates. Application of treatment (B) resulted in highly significant increase in yield production of Gemmeza10 and Misr2 as compared to treatment (A). Grain yield of different wheat varieties grown under treatment (B) could be ranked in the following descending order: Misr2 > Gemmeza10 > Sids12. While under treatment (A) it could be arranged in the following descending order: Misr2 > Sids12 > Gemmeza10. On the other hand, the overall means indicated non-significant difference between all wheat verities. The highest values of water and irrigation use efficiency as well as heat use efficiency were obtained with treatment (B). The equation used in the present study is available to estimate ET a under arid climate with drip irrigation system. journal h omepage: http :/ / www .e lsev ie r. co m/ lo cate/ j rras 1

This research was conducted to identify areas of Ardabil province susceptible for Helianthus annuus cultivation. The aim of this study was to identify climatic factors for H. annuus cultivation using TOPSIS method and zoning areas susceptible to cultivating this product using ArcGIS in Ardabil province. In this research, climatic data such as minimum temperature, precipitation, and relative humidity were used along with slope, soil and altitude maps of 10 synoptic stations during 22 years (1994 to 2015). Weighing the layers was carried out using the TOPSIS method and the desirable climatic conditions of the H. annuus product, and a digital map of the data was obtained in the ArcGIS. Positive ideal map, negative ideal and final map of H. annuus cultivation in Ardabil province were prepared by integrating of maps in ArcGIS. The final results showed that about 25.89% of the province's area is without limitation, 22.96% with a low limitation, 26.89% with a moderate limitation, and 24.77% with a severe limitation for H. annuus cultivation. As a result, the cultivation of this product was without limitation in terms of temperature and relative humidity and is faced with limitation in terms of water requirement supply.

“…GDD is used by horticulturalists to predict phenological events such as flowering or fruit ripening. GDD for each day is calculated as an average daily temperature minus the baseline temperature (Neamatollahi, Bannayan, Jahansuz, Struik, & Farid, 2012). This index is used to evaluate the suitability of a region for different crops, monitor the growth and development of crops and pests, determine optimal timing for application of fertilizers and pesticides, and plan planting days to stagger crop harvest.…”

Field experiments were conducted to investigate the effects of residue and tillage on growth and yield of melon. Tillage treatments included conventional tillage (using a moldboard plough and two passes with a disk harrow), minimum tillage (one pass with a disk harrow), and no tillage (NT). Residue treatments included the application of 0%, 30% and 60% residue. Yield and yield components were obtained for all treatments. Tillage significantly affected yield and its components (P ≤ 0.05). The maximum FWPP (2.678 kg), NFPP (6.799), D (18.49 cm), L (45.93 cm), S (12.51%) and RUE (2.470) and yield (16.17 t/ ha) were recorded in the conventional tillage treatment. Also, maximum FWPP (2.192 kg), NFPP (5.353), D (16.66 cm), L (39.52 cm) and yield (12.83 t/ha) were observed in the 30% residue treatment. In terms of the interaction effects, maximum FWPP (2.850 kg), NFPP (6.790), D (20.71 cm), L (53.53 cm) and yield (17.09 t/ha) were obtained in the conventional tillage + 30% residue treatment. Therefore, the use of a moldboard plough followed by two passes with a disk harrow, in concert with 30% residue treatment, were maximizing the yield Almost all growth indicators had the optimum values in the conservation tillage treatments.
