Title

Effects of different soil textures on the growth and distribution of root system and yield in peanut

Jia Li Chinese Journal of Plant Ecology 2013

Other claims from this paper (11)

Intervention effect Root dry matter weight of peanut was significantly higher in sandy and loam soils than in clay soil.
Observation In clay soil, the root system of peanut was mainly distributed in the shallow soil layer.
Observation In clay soil, the decrease of root activity in the upper layers was slower in the late growth period.
Intervention effect Sandy soil was helpful for the root system of peanut to grow to the deeper soil layer.
Intervention effect Sandy soil favored enlargement of the peanut pod.
Intervention effect Dry matter accumulation of peanut pod in sandy soil was earlier and faster.
Intervention effect Dry matter accumulation in the later growth period was less in sandy soil.
Observation In loam soil, dry matter accumulation of peanut pod was mainly concentrated in middle and later periods.
Intervention effect Clay soil was not suitable for dry matter accumulation of peanut pod in the entire growth period.
Intervention effect Pod yield, kernel yield and available pod number were largest in loam soil, second in sandy soil and lowest in clay soil.
Recommendation The authors suggest loam soil, with mid-levels of aeration and water and fertilizer conservation, is most suitable for the growth and yield of peanut.

Title

Effects of Root Cutting in Different Depths on Root System Distribution,Senescence Character and Yield of Peanut

Guo Qin Acta Agriculturae Boreali-Sinica 2015

Other claims from this paper (7)

Intervention effect Moderate root-cutting slowed root system growth at the early stage of peanut.
Intervention effect Moderate root-cutting promoted root growth in deep soil of peanut.
Intervention effect Moderate root-cutting increased the proportion of middle and lower segments of the peanut root system.
Intervention effect Moderate root-cutting reduced root senescence in peanut by delaying the time of maximum root vigor, SOD and POD activity.
Intervention effect Moderate root-cutting reduced malondialdehyde (MDA) content in the root system of each soil layer of peanut.
Intervention effect Moderate root-cutting improved valid pods, pod yield and seed yield of peanut, whereas excessive root-cutting did not.
Recommendation The authors recommend a root-cutting depth of 10 to 15 cm for peanut.
