“…The RLD increased with increasing N fertilizer rates (up to 150 kg/ha), then decreased thereafter and the highest RLD was under N4 treatment at the 20-30 cm depth; the lowest was 1.95 cm/cm 3 under N1 at the 0-10 cm depth (Table 9). These results are in agreement with previous re-ports (Materechera and Mloza-Banda 1997;Raj et al 2013;Mahgoub et al 2017;De Giorgio and Fornaro 2012).…”

“…Sathiyavani et al (2017) found that higher nutrient supplies in the soil may also decrease root length but increase root weight. The root length density and specific root length of corn and cowpea decreased with soil depth (Mahgoub et al 2017). Irrigation with high intervals such as drip irrigation that keeps the environment moist enough for water absorption prevents root growth to different soil depths.…”

Deficiencies in water and nitrogen (N) can lead to poor crop growth and production. This study was carried out during 2012-2014 to determine (1) the effect of drip irrigation regimes and N fertilizer rates on root length density (RLD) of corn (Zea mays L. cv. Single cross 704) and soil moisture dynamics and (2) the relationship between root development and water availability. The experiment was arranged into a split-plot design with three irrigation regimes as the main factor (I1 = 60, I2 = 80, and I3 = 100% evapotranspiration [ETc]) and five levels of N fertilizer (N1 = 0, N2 = 50, N3 = 100, N4 = 150 and N5 = 200 kg/ha) as the subfactor. The combination I1N4 produced the highest grain yield and yield components while I3N5 gave the lowest performance. The highest RLD was recorded at full irrigation water requirement and it increased with increasing N rate, but not in a linear trend, as higher N rates showed less effect. Nitrogen application under drip irrigation increased the RLD in soil depending on irrigation level. Soil moisture was optimized at full irrigation water requirement and 150 kg/ha N.

“…At surface irrigation, root length density of cowpea reached to soil depth 30-40 cm with lateral distances 5-10 cm and 15-20 cm. Meanwhile, vertical distribution of root length density of maize was increased with soil depth till 20-25 cm, and then it decreased till soil depth 35-40 cm (Mahgoub et al, 2017). Although, Basso and Ritchie (2018) demonstrating that maize (Zea mays L.) productivity could be increased with no change in water use rate and result in increased WUE, the root structure of maize plays a major role in lodging, the uptake of nutrients and water and survival under unfavorable soil conditions (Sah et al, 2020).…”

The present investigation was carried out at Giza Agricultural Experiments and Research Station, Agricultural Research Center (ARC), Giza, Egypt during the two successive seasons 2016 and 2017. The objective of this investigation was to assess the effect of applied irrigation water, infestation with insects and infection with virus on cowpea and maize productivity, as well as farmer income under intercropping condition. The experiment included nine treatments which were the combinations between three applied irrigation water levels (80, 100 and 120% of the recommended applied irrigation water level of maize) and three cropping systems (intercropping cowpea with maize, sole cowpea and sole maize), in addition to recommended sole maize that grown on ridges 70 cm width and received 100% of applied irrigation water. The experimental design was a strip plot with three replications. Irrigation water treatments were randomly assigned to the vertical strips and cropping systems were allocated in the horizental strips. Data indicated that the highest applied irrigation water level (120% ETo) had higher water consumptive use than the others. The intercrops had higher water consumptive use than those of sole plantings. With respect to maize crop, increasing applied irrigation water from 80 to 120% ETo significantly increased infestation with aphids, jassids, Hawaiian beet webworm, cotton leafworm and whiteflies on maize leaves, as well as higher grain yield per ha and its attributes. Intercropped maize had higher infestation with aphids, jassids, cotton leafworm and whiteflies, as well as ear leaf area per plant than those of sole maize, meanwhile, the reverse was true for greater sugarcane borer. Intercropped maize plants that received the highest applied irrigation water (120% ETo) had higher infestation with aphids, jassids and cotton leaf worm on maize leaves than the other treatments, meanwhile higher ear leaf area per plant was recorded by application of the recommended applied irrigation water of maize (100% ETo). With respect to cowpea crop, increasing applied irrigation water from 80 to 120% ETo significantly increased infestation with aphids, jassids, leaf miner fly, Hawaiian beet webworm, cotton leafworm and whiteflies, as well as soybean mosaic virus (SMV) infection on cowpea leaves, beside higher plant height, number of branches per plant and forage yield per ha. Intercropped cowpea had lower infestation with aphids, jassids, leaf miner fly and Hawaiian beet webworm, as well as lower SMV infection and number of branches per plant and forage yield per ha than those of sole cowpea. Sole cowpea that received the recommended applied irrigation water of maize (100% ETo) had higher infestation with Hawaiian beet webworm, jassids and leaf miner fly on cowpea leaves than the other treatments, meanwhile, SMV infection was not by the interaction between applied irrigation water levels and cropping systems. Sole cowpea that received the highest applied irrigation water level (120% ETo) had a higher number of branches per ...

“…Besides, 77.82% of FRB was concentrated in the top 20cm of soil, which was similar to previous results drawn from other forests (Qin et al, 2013). In terms of the seasonal pattern of FRB, the peak value usually appears in spring and autumn, most of the patterns are bimodal (Mahgoub et al 2017). However, in some forest ecosystems, the maximum fine root biomass appears only once within a year, which could be in spring, summer or autumn.…”

Despite the recognized importance of the fine roots in influencing tree growth and stand productivity, knowledge of fine roots is still limited, especially in adverse sites like saline-alkali land. In this paper, we applied sequential soil coring to assess the influence of stand age, soil depth and growth month on fine roots in 3, 16, 30 and 40-year old Robinia pseudoacacia stand in coastal saline-alkali land of the Yellow River Delta, China. Besides, the correlations between fine roots characteristics fine root biomass (FRB), fine root length (FRL), fine root surface area (FRSA), specific root length (SRL) and specific root surface area (SRA)) and abiotic factors (temperature, precipitation, soil water content (SWC), soil salt content (SSC) and soil nutrients) were discussed. In this paper, FRB, FRL, FRSA, SWC and soil nutrients increased, while SRL and SWC decreased with increasing stand age. Vertically, fine roots were concentrated in a 0-20 cm soil layer. SRL, SRA, SWC and SSC increased, while soil nutrients decreased with increasing soil depth. Temporally, FRB, FRL, FRSA, soil hydrolytic nitrogen and available potassium (AK) shared similar patterns and reached maximum in May or September. In July, SWC, SRL and SRA reached maximum while SSC reached the minimum. Soil total nitrogen (TN) and organic matter 2 (OM) were highest in May or November. Correlation analysis showed that FRB, FRL and FRSA were negatively correlated with SWC and SSC, positively correlated with HN and AK. SRL was positively correlated with temperature, precipitation, SWC and SSC, while negatively correlated with TN. Among abiotic factors, temperature, precipitation and HN played key roles in the study area. This study improves our understanding of the fine roots and belowground ecology of R. pseudoacacia stands in coastal saline-alkali land of the Yellow River Delta.
