“…Ploughing caused a decrease in soil reflection coefficient and exposed the darker, more energy absorbing soiL That is why tiie soil ploughed with mouldboard and cultivator warmed up more rapidly than untillcd and rotary tiller ones (Table 2). Similar findings were also reported by GATES and HANKS (1967) and KHAN (1988). Oxygen requirement varied witk the stage of plant development, increasing with increases in soil temperature (WILUAMSON 1964).…”

“…The soil under zero tillage had the majomum bulk densitv and hence the minimutn porosity. Higher values of bulk density were observed under ll than under convcntiona] or plougji (BRUCE et al 1990, RHOTON et al 1993 TTie increase in bulk density would increase penetration resistance and decrease the total porosity, and in most cases this reduction occurred at the cost of aeration porosity (KHAN 1984). Lower aeration porosities for zero tillage that at higher water content, this KHAH treatment is likely to affect plant growth adversely because of the restricted gas exchange.…”

Air‐ porosity of soil can be altered by tillage. Therefore, it plays a significant role in protecting plants against deficient aeration during critical periods of their life cycle. The effect of five tillage treatments (mouldboard, cultivator, rotary tiller, wedge and zero tillage) and three mulch treatments (paddy straw, rice husk and bare) 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 (utilsol). These experiments were conducted for two consecutive seasons. ODR values were higher in tilled plots. Among tillage treatments, the highest ODR was recorded under mouldboard (60.51 × 10‐8 g cm‐2 min‐1), followed closely by cultivator (57.65 × 10‐8g cm‐2 min‐1), and it was lowest under rotary tiller (46.29 × 10‐8 g cm‐2 min‐1). During the later growth stages and also in lower soil depths, the differences between the values of ODR narrowed down. Among mulch treatments, plots with rice husk (53.98 × 10‐8 g cm‐2 min‐1), had the higher ODR values. Bulk density was lower, whereas total and aeration porosity were higher, under mouldboard and cultivator. Soil temperatures were also higher under mouldboard and cultivator tilled plots.

“…Furthermore, the results showed that the 60 cm depth of tillage provides better edaphic environmental growing conditions compared to other treatments for tillage (20 cm depth, traditional tillage). The results are consistent with those stated (Khan, 1984;Zhang and Fang, 2007). Other scientists Higashida and Yamagami (2003) also noted in another research for Wheat that growth of winter wheat crop was stimulated by deep tillage.…”

“…It may also be seen from the table, that as the soil depth increases, the ODR decreases. The decrease in ODR values with the lapse of time in all treatments is attributed to a general increase in bulk density and resultant decrease in aeration (noncapillary) porosity (Khan 1998a). The values of ODR also decrease with increased bulk density at constant moisture (Mohsin and Khan 1977).…”

“…Hazra et al (1973) also reported a lower bulk density under vegetative and polyethylene mulches. Mulches reduce the surface crusting and thereby soil bulk density (Lyford and Qashu 1969, and Khan 1984). Aeration porosity is inversely related to the bulk density.…”

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.
