“…Water content is also the most difficult to manage. The way a soil is managed will play an important part in determining its thermal conductivity (Aggarwal et al, 2009;Maity and Aggarwal, 2012). Any practice or process, which tends to cause soil compaction will increase bulk density and decrease porosity of a soil.…”

). The range of thermal conductivity (K) for was highest for black soil followed by alluvial sandy loam and red loamy sand soil. Thermal properties were the highest for black clay soil followed by alluvial sandy loam soil and were the lowest in red loamy sand soil. In all soil types, C v and K were higher in compacted soil as compare to loose soil. Hence, downward heat flux was more in compacted soil. The black color of the clay soil might have exerted added effects on the increase in the temperature because of more heat absorption whereas the moderating effect of higher moisture on ST was not prominent. Whereas in lighter colour alluvial soil due to moderating effect of soil water on ST would lead to the reduction evaporational losses and improvement in water use efficiency of crop.

An attempt has been made to study the effect of elevated temperature on soil hydrothermal regimes and winter wheat growth under simulated warming in temperature gradient tunnel (TGT). Results showed that bulk density (BDs) of 0, 0.9, and 2.5 °C were significantly different whereas BDs of 2.8 and 3.5 °C were not significantly different. Water filled pore space (WFPS) was maximum at 3.5 °C temperature rise and varied between 43.80 and 98.55%. Soil surface temperature (ST) at different dates of sowing increased with rise in sensor temperature and highest ST was observed at S5 sensors (3.5 °C temperature rise). Temperature and its difference were high for the top soil, and were stable for the deep soil. Photosynthesis rate (μmol CO m s) of wheat was lower at higher temperature in different growth stages of wheat. In wheat, stomatal conductance declined from 0.67 to 0.44 mol m s with temperature rise. Stomatal conductance decreased with increase in soil temperature and gravimetric soil moisture content (SWC). In TGT, 0 °C temperature rise showed highest root weight density (RWD) (5.95 mg cm); whereas, 2.8 and 3.5 °C showed lowest RWD (4.90 mg cm). Harvest index was maximum (0.37) with 0 °C temperature rise, and it decreased with increase in temperature, which indicated that both grain and shoot biomass decreased with increase in temperature. Intensive studies are needed to quantify the soil hydrothermal regimes inside TGT along with the crop growth parameters.
