“…It indicated that plant requires sufficient moisture to fully utilize applied nutrients. Soil compaction reduced both the water and nutrient use efficiencies of wheat and sorghum (Sorghum bicolor) by about 38 and 22%, respectively, in fine loamy soil [36]. Maximum root yield was noticed when higher dose of fertilizer was applied along with maximum number of irrigation.…”

A field experiment was conducted during the year 2007-2008 and 2008-2009 in Bhubaneswar, India to study the effect of tillage, irrigation and nutrient levels on growth and yield of sweet potato (Ipomoea batatas L.) in rice fallow. The results revealed that the conventional tillage system of sweet potato planting recorded maximum fresh root yield. During the year 2007-2008 and 2008-2009, the fresh root yield in this system was 4.6% and 30.3% higher than the minimum tillage treatment, respectively. Similarly 5.6% and 21.7% higher green fodder yields were obtained in conventional tillage compared to minimum tillage treatment during the year 2007-2008 and 2008-2009, respectively. But lower consumptive use and water use efficiency (WUE) were observed in conventional tillage than minimum tillage. Increasing irrigation and nutrient levels increased root and fodder yield significantly in both the years as well as reduced the soil compactness. The consumptive use and WUE were decreased with increasing irrigation levels, and increased with increasing levels of nutrients. Minimum tillage has advanced planting of sweet potato 15 to 17 days and produced 80–90% root and fodder yield of conventional tillage.

“…In addition to restricting root growth into deeper soil layer, high bulk density may also interfere with the movement and distribution of water in the profile [14], nutrient availability, and uptake by plants, which may eventually affect plant growth. Other studies [15][16][17] have also shown that soil compaction reduced crop yields due to increased resistance to root growth and decrease in water and nutrient use efficiency. However, it seems that the impact of soil compaction on root growth and biomass of different tree species in compacted soils varies considerably [18,19].…”

The impact of soil compaction on bulk density and root biomass ofQuercus petraeaL. was assessed after 85 years of reclamation of post-lignite mining soil at Welzow-South, in Lusatia, Germany. Bulk density of core soils sampled from 20 to 25 cm, 100 to 105 cm, and 200 to 205 cm depths and oven-dried biomass ofQ. petraearoots sampled from 0 to 30 cm and at successive depths of 20 cm, up to 210 cm depth at compacted and uncompacted sites were determined. Bulk density was significantly higher at 20 to 25 cm (1.74±0.09 g cm−3) and 100 to 105 cm (1.65±0.06 g cm−3) depths of the compacted site. Likewise, compaction induced significant greater root biomass within the 0 to 70 cm depth with higher bulk density; root biomass at this depth was 2-fold greater compared to the uncompacted site. Root biomass decreased with soil depth and showed significant relationship with depth at both sites. The result indicates that, after 85 years of reclamation, the impact of soil compaction persisted as evident in higher bulk density and greater root biomass.

“…The results obtained in this study confirmed these observations, as the decrease in root number, length, and indexes of soil root distribution in severely compacted soil were greater for triticale than for maize. According to Ishaq et al (2001), the species with deep tap roots were capable of minimising the detrimental effect of soil compaction. A study by Hoffmann and Jungk (1995) suggested that in the compacted soil shoot growth was decreased when root growth was restricted by soil compaction and/or water saturation.…”

“…In this study, the seedlings of two maize hybrids and two triticale breeding forms (sensitive and resistant to soil density stress) were grown in the soil of low (L D ) and high (H D ) density and under poor [P N ]) and high (H N ) concentrations. Thus, soil density combined with poor or high dose of nitrogen represented different environmental stresses occurring in the field Laine, Ourry, and Boucaud (1995), Tanaka et al, 1995;Ishaq, Ibrahim, Hassan, Saaeed, & Lal, 2001;Ogawa et al, 2014).…”

Responses of maize and triticale seedlings, differing in the susceptibility to soil density stress, and grown under low (LD) or high (HD) soil density and poor (PN), high (HN) or control (CN) nitrogen content in soil were investigated in relation to changes in physiological parameters—dry matter of shoot (S), root (R), shoot to root ratio (S/R), relative growth ratio of shoot and root (RGR), chlorophyll content (SPAD), total roots number and length (TRN, TRL), root penetration ability (RPA) and ratio of deep rooting (RDR). The seedlings grown under high soil density (HD) and control N‐soil content (CN) in comparison with LD and CN treatments showed a decrease in all measured parameters. Under poor and high nitrogen content, changes in the traits were higher for triticale than for maize. Higher differences between resistant and sensitive genotypes in TRN, TRL, RPA and RDR were observed particularly in the seedlings grown under HD treatment. Differences in parameters values between seedlings grown under control and nitrogen‐rich soil may be considered as a positive interaction between stresses. Our results suggest that the type of root structure (scattered, dimorphic) would be helpful in enhancing modelling and agronomic management for improved of plant stress tolerance.
