“…On heavier soils direct drilling may even eliminate the need for a pre-or post-sowing irrigation in the IGP (Hobbs and Gupta 2003b), as in Australian RW systems. In contrast with the results of the farmer trials in the IGP, Gajri et al (1992) found lower yields of direct drilled wheat compared with conventionally or deep tilled wheat over three consecutive years on a sandy loam. Tillage resulted in deeper and denser rooting and increased transpirational and N use effi ciency.…”

“…The relative importance ascribed to each of the above reasons varies. For example, Tabbal et al (2002) consider that puddling in central Luzon, Philippines, is done primarily for weed control, whereas Kukal and Aggarwal (2003) and Gajri et al (1992) place more emphasis on its role in reducing percolation losses in NW India, where soils are highly permeable. Puddling is not essential for rice growth and yield, with many studies (but not all e.g.…”

“…Puddling for rice induces high bulk density, high soil strength and low permeability in sub-surface layers (Sharma and DeDatta 1986;Aggarwal et al, 1995;Kukal and Aggarwal 2003), which can restrict root development and water and nutrient use from the soil profi le for wheat after rice (Sur et al, 1981;Gajri et al, 1992). However the impact of puddling for rice on the performance of wheat after rice is variable across sites and years (Table 1; Sharma et al, 2003).…”

“…From an agronomical point of view, Gajri et al (1992) observed that conventional tillage (CT) increased the transpiration rate, and simultaneously the grain yield, compared to non-tillage (NT). While the adoption of NT brought the benefit of increased water storage in the soil, a drawback is the reduced availability of inorganic nitrogen (López-Bellido and López-Bellido 2001).…”

The objective of this work was to determine the change for straw production, carbon and ash content in vegetative tissues through ten cycles of recurrent selection in bread wheat, evaluated under tilled (CT) and non-tilled (NT) soils. Twenty-four wheat genotypes, four for each one of the 0, 2, 4, 6, 8 and 10 cycles of recurrent selection (RS), were used in this study. Experiments were established during two successive seasons. Ash content was expressed on dry mass basis. To estimate the carbon content, we based our calculation on the assumption that organic matter is 50% carbon. Straw dry weight was measured. For each trait, a linear mixed model (regression) was fitted to the experimental data. In response to the number of selection cycles, the ash content percentage increased under CT and decreased under NT. Carbon content decreases under CT, but increases under NT. The sequestered straw carbon and the straw production significantly decrease under CT meanwhile there was no change under NT. The observed increase for straw ash content would be related to the highest rate of transpiration in the more advanced recurrent selection cycles. Consistent with these results, the percentage of straw carbon content decreased because of the mobilization of reserves from the stems and leaves to the grains.

“…layers impedes root growth of the subsequent crop(s) and causes nutrient and water deficits (Gajri et al 1992). Subsoiling is a process that breaks the hardpan layer and the compacted layer of soil without turning over the infertile subsoil at the top (Singh et al 2013) and can improve soil structure by eliminating soil compaction (Shi et al 2016).…”

The North China Plain (NCP) serves as China’s second most important maize production region. Rotary tillage, a popular method used in winter wheat/summer maize systems in the region, has adverse effects on maize production. The current study was conducted to determine whether rotary tillage after subsoiling in the winter wheat season (RS) improves the grain-filling rate and yield of summer maize by decreasing soil bulk density, when compared with rotary tillage (R), in the NCP. The RS treatment decreased soil bulk density and increased soil moisture in the summer maize season when compared with the R treatment. Root number under the RS treatment at 8 collar and silking stages was 22.4−35.3% and 8.0−11.7% greater than under the R treatment, respectively. The RS treatment significantly enhanced the grain-filling rate and grain weight as compared to the R treatment. Yield, thousand grain weight, biomass, and harvest index under the RS treatment were 7.7, 7.2, 2.3 and 5.3% higher than under the R treatment. Thousands grain weight was correlated with soil bulk density and soil moisture after silking. Consequently, the increase in grain weight and yield of summer maize resulted from the decrease in soil bulk density and a consequent increase in soil moisture, root number and grain-filling rate.
