“…These effects can be linked to morphological and physiological changes of plants growing in a mechanically impeded medium. Morphological changes mainly include restriction of root extension and shoot growth, and modification of the rooting pattern and root diameter (Atwell, 1989;Dexter, 1986;Iijima et al, 1991;Lipiec et al, 199l;Taylor and Brar, 1991). The physiological mechanisms resulting from compaction, such as changes in nutrient uptake, have also been clearly shown (Dolan et al, 1992;Douglas and Crowford, 1991;Lindberg and Pettersson, 1985;Wolkowski, 1990).…”

Influence of mechanical impedance on root exudation of maize seedlings at two development stages

Studies were undertaken to evaluate the effects of mechanical impedance on root exudation by maize (Zea mays L., var Dea) and to examine the importance of these effects in relation to the stage of plant development. Plants were grown under sterile and hydroponic conditions. Mechanical impedance was simulated using glass beads of 1 mm diameter. This treatment was compared with a control without beads. Results demonstrated that plant growth was influenced by mechanical impedance. Mechanical impedance markedly affected the growth of the shoot, whether this was measured as leaf area or total dry matter. Besides increasing root/shoot biomass ratios, mechanical impedances also stimulated root exudation of organic and inorganic compounds. Stressed plants lost more nitrogenous compounds than control plants. Otherwise, the percentage of released carbon decreased. Depending on the developmental stage of the plant, there was a large variation in the magnitude and time course on mechanical impedance effects. The effects of mechanical impedance persist and accentuate with time.

“…These changes in physical properties of soils lead to reduced plant growth and production mainly by restricting root growth, decreased soil water and nutrient availability and lower soil aeration (Domzal et al, 1991). The restrictive effect of soil compaction can be physical and physiological, affecting plant growth and yield (Iijima et al, 1991). Nitrogen (N) fertilization plays a significant role in improving soil fertility (Habtegebrial et al, 2007), and results in increased vegetative growth and ISSN : 0974-9411 (Print), 2231-5209 (Online) All Rights Reserved © Applied and Natural Science Foundation www.ansfoundation.org biomass of maize (Ogola et al, 2002).…”

Abstract:The magnitude of yield reduction due to soil compaction is variable and depends on the soil type, fertility status and other soil and environmental factors. The present investigation was carried out at the research farm, Department of Soil Science, Punjab Agricultural University, Ludhiana. The experiment was conducted to evaluate the effect of different levels of subsoil compaction and nitrogen fertilization on maize phenology, yield and heat use efficiency ) treatment during the year 2012 and 2013, respectively. The tasseling and silking stage was delayed, while physiological maturity was advanced under C 2 subsoil compaction treatment than that in C 0 treatment. The N 2 treatment improved the yield by 14.9 and 13.9 % and HUE by 15.2 and 14.3 % than that in N 0 treatment during the year 2012 and 2013, respectively. Maize took more days to reach physiological maturity under N 2 treatment as compared to N 0 treatment. Phenothermal index (PTI) showed that crop reached different stages earlier under C 1 and C 2 than that of C 0. The data emphasized the need to take care of soil strength and soil temperature related parameters along with weather conditions for better yield prediction using thermal time.

“…As reported by Iijima et al [27], mechanical impedance on plant growth generally determines not only changes in root morphology, but also a reduction of shoot matter. On the contrary, in our experience, since at the earlier stages of growth, micronized zeolite (M2) induced a significant increase in maize shoot length and weight, indicating a different mechanism of action.…”

Clinoptilolite has been successfully used in growing media for containerized horticultural and floricultural production. However, limited data exist on the effects and interaction between particle size and organic nutrient enrichment of the clinoptilolite. One granular (1-3 mm) and micronized (<30 μm) clinoptilolite was added to quartz sand, an inert growing substrate, at two doses (0.1% and 3% v/v), without or with addition of wine vinasse as nutrient source at four concentrations (0 mg F L subst -1 , 10 mg F L subst -1 , 100 mg F L subst -1 and 1000 mg F L subst -1 ) to evaluate their effect on root growth for five days or the appearance of the second true leaf.Root mucigel was produced in zones where clinoptilolite particles adhered to the root surface. Microscopic analysis of isolated roots showed the increase of secondary roots and the proliferation of root hairs in maize treated with both micronized and granular clinoptilolite, with the contemporary production of root mucigel in zones where zeolite particles adhered to the root surface. It is hypothesized that the enhanced production of mucigel by root cells can favour not only the penetration of roots into the inert substrate, but also the solubilization of organic matter and nutrient availability, in particular when micronized clinoptilolite was present in the growing medium. Therefore, micronized clinoptilolite behaved as a sort of a "physical stimulant" for roots during seedlings, promoting, as a consequence, maize shoot development. Effectively, the highest increase in shoot growth was observed at the highest dose (3% v/v) of micronized zeolite, with the optimal rate of organic fertilizer (100 mg F L subst -1 ).
