Special Issue Information

Dear Colleagues,

Weather conditions have a significant impact on the growth, development, and yield of crop plants. The extent of this phenomenon is difficult to estimate, as each species and variety behaves differently. It is, therefore, crucial to determine their impact on yield using mathematical models that describe the meteorological phenomena in question and explain the processes in the soil–plant–atmosphere system.

Adapting and preparing agriculture for the observed and projected changes in climate conditions is urgently needed and requires the involvement of water users, whose decisions directly affect the availability and quality of water in rural areas. With droughts and agricultural water shortages predicted to become more frequent, water is becoming a strategic asset for both present and future generations. Therefore, measures to adapt plants to climate change and combat the negative effects of various stresses, including drought, high or low temperatures, and salinity, are extremely important. A detailed study and understanding of the importance of meteorological phenomena in plant cultivation are essential to achieving productive yields and food security.

The main topics covered in this Special Issue include, but are not limited to, the following:

  • Estimating the water needs of crops;
  • Methods for adapting plants to climate change;
  • Precision and water-saving irrigation;
  • Yield estimation based on regional climate models;
  • Impact of extreme weather events on crop production;
  • Research into new crop varieties resistant to different conditions;
  • Plant yield after the application of fertilizers and agro-technical treatments;
  • Effects of biotic and abiotic stresses on plants and their parameters.

An experiment was conducted to determine the effect of water stress on yield and various physiological parameters, including the crop water stress index for tomatoes in the Central Anatolian region of Turkey. For this purpose, the irrigation schedule used in this study includes 120%, 100%, 80%, and 60% (I120, I100, I80, I60) of evaporation from the gravimetrically. Water deficit was found to cause a stress effect in tomato plants, which was reflected in changes in plants’ morphological and pomological function (such as stem diameter, fruit weight, pH, titratable acidity, and total soluble solids). Irrigation levels had a significant effect on the total yield of tomatoes. The lowest water use efficiency (WUE) was obtained from the I60, while the highest WUE was found in the I100 irrigation level. The CWSI was calculated using an empirical approach from measurements of infrared canopy temperatures, ambient air temperatures, and vapor pressure deficit values for four irrigation levels. The crop water stress index (CWSI) values ranged from −0.63 to a maximum value of 0.53 in I120, from −0.27 to 0.63 in I100, from 0.06 to 0.80 in I80, and from 0.37 to 0.97 in I60. There was a significant relation between yield and CWSI. The yield was correlated with mean CWSI values, and the linear equation Total yield = −2398.9CWSI + 1240.4 can be used for yield prediction. The results revealed that the CWSI value was useful for evaluating crop water stress in tomatoes and predicting yield. Full article
