“…Soil temperatures were not as high under black plastic because the soil received only a portion of the incoming energy absorbed by the black film. Similar results were reported by Adams (1962), Burrow and Larson (1962) and Revut (1973) and Khan (1998b). ODR was also found to be significantly higher under vegetative mulches followed by plastic mulches in comparison to that in bare plots.…”

“…Studies relating crop production to soil temperature have caused wide acceptance of the value of mulches for providing a favourable crop environment for increasing crop yield in cold temperate climates. Adams (1962) reported a significant increase in pod yields with the use of a plastic mulch, which was attributed to the warmer soil temperatures. Warmer temperature may increase the absorption of nutrients and water as well as the production and translocation of carbohydrates.…”

The assessment of the importance of soil aeration for various plant characteristics and environmental conditions is necessary to evaluate the oxygen relations to the crops. The root environment as a solid‐liquid matrix depends upon soil structure and moisture condition. A limited oxygen supply restricts the root development and also reduces the nitrogen fixation in peanuts. Soil surface conditions can be altered by mulching and plays a significant role in protecting the plants against deficient aeration during critical periods of growth phases. The effects of eight mulching treatments (rice husk, rice husk‐incorporated, paddy straw, sawdust, water mulch, clear polyethylene, black polyethylene and control) on the soil oxygen diffusion rate (ODR) during the various growth phases of peanut crop (Arachis hypogaea L.) were investigated on a lateritic sandy loam soil (ultisols). These experiments were conducted for two consecutive seasons. ODR values were higher in mulched plots. With the progress of growth stages and also in deeper soil depths, the differences between the values of ODR among treatments narrowed down. The influence of mulches on other physical edaphic properties like bulk density, aeration (noncapillary) porosity and soil temperature were also studied. Mulches reduced the surface crusting and thereby soil bulk density; and increased the aeration porosity and ODR. Soil temperature was higher under plastic mulches whereas vegetative mulches suppressed it.

“…The combined effects of radiation interception and evaporative cooling were responsible for lower soil temperature under vegetative mulches. The materials like straw and other plant waste products like Adams (1965), Webster et al (1967) and Nanda et al (1999). The temperature of surface soil at 3 p.m. was 34 0 C due to straw mulching whereas temperatures of non-mulched plots were as high as 42 0 C (Nanda et al, 2000).…”

Soil temperature is recognised as one of the most important factors in crop production. Some degree of manual control of soil temperature is possible through regulation of soil surface cover. The effect of eight mulch treatments ( rice husk, rice husk incorporated, paddy straw, saw dust, water mulch, transparent polyethylene, black polyethylene and bare) on the soil temperature during various growth phases of peanut crop (Arachis hypogaea L.) were investigated on a lateritic sandy loam soil (ultisols). These experiments were conducted for two consecutive seasons. Plastic mulches raised the temperature upto 5 0 C generally during afternoon whereas vegetative mulches depressed the same. Between the plastic mulches, black polyethylene covered field recorded lower soil temperature (upto 2 0 C) than the transparent one. Water mulches due to their high specific heat capacity acted as a heat sink during the day and heat source at night. The vegetative mulches suppressed the soil temperature and did not allow the radiant energy to contact the soil directly and emitted back the energy to the atmosphere. Among the vegetative mulches, rice husk and saw dust proved better than paddy straw and rice husk incorporated. The type and amount of soil cover which modify micro-climate and soil edaphic environment, may help to plan the farming practice for better crop growth and production.

“…Significantly higher grain yields have been obtained by simply raising soil temperature during early growth stages (Adams 1962(Adams , 1970. Sorghum cultivars produced more leaves (Hesketh et al 1969;Quinby et al 1973), had delayed floral initiation (Caddel …”
