“…At lower latitudes, two out of four shaded potato cultivars showed no changes in height. One cultivar showed an increase in height at 30% shade, and the other cultivar at 50% shade [22]. The authors ascribed this to a higher auxin level while the gibberellin level also increased, which promoted stem growth.…”

Impact of Different Shading Levels on Growth, Yield and Quality of Potato (Solanum tuberosum L.)

In agroforestry systems (AFS), trees shade the understory crop to a certain extent. Potato is considered a shade-tolerant crop and was thus tested under the given total solar irradiance and climatic conditions of Southwestern Germany for its potential suitability in an AFS. To gain a better understanding of the effects of shade on growth, yield and quality; a three-year field experiment with different artificial shading levels (12%, 26% and 50%) was established. Significant changes in growth occurred at 50% shading. While plant emergence was not affected by shade, flowering was slightly delayed by about three days. Days until senescence also showed a delay under 50% shade. The number of tubers per plant and tuber mass per plant were reduced by about 53% and 69% under 50% shade. Depending on the year, tuber dry matter yield showed a decrease of 19–44% at 50% shade, while starch content showed no significant differences under shade compared to unshaded treatment. The number of stems per plant, plant height and foliage mass per plant as well as tuber fraction, black spot bruise and macronutrient content were unaffected. Overall, potato seems to tolerate shading and can therefore be integrated in an AFS, and can cope with a reduced total irradiance up to 26%.

“…Other studies revealed that, early paclobutrazol application could clearly reduce the stem length in potato, accompanied with a significant increase in the number of tubers per plant, as well as the reduction in plant height and modification in the aboveground structure (Rodriguez-Falcon et al, 2006;Mariana and Hamdani, 2016). However, in this study, we showed that, the application of paclobutrazol has significant influence on increasing taproot weight and diameter, this outcome is supported by the findings of Bidadi et al (2010) in Arabidopsis, Wang et al (2015) in carrot and Mariana and Hamdani (2016) in potato. In contrast, our result showed that, GA3 treatment revealed a clear increase in shoot weight (Fig.…”

To cite this paper: Jabir, B. AbstractRadish (Raphanus sativus L), is a taproot plant that undergoes noticeable organ size modification during plant growth and development. Paclobutrazol (PBZ) inhibits gibberellin biosynthesis and stimulates the proliferation and expansion of plant root cells in growth and developmental stages. Our study aims to examine the effects of PBZ treatment on the storage organ of plant. Four treatments were applied at the pre-cortex splitting stage of "Nau-yh" radish plant. Foliar spray treatments including PBZ (50 mg/L), gibberellic acid (GA3, 150 mg/L) and a mix of GA3+PBZ (150+50 mg/L) were applied. The results revealed considerable improvement in taproot growth and decreases development in aerial parts after 48 days of the growth. Paclobutrazol treatment showed enhanced growth parameters, most notably, root weight was 33% higher than GA 3 treatment, 28% higher than the control (H2O), and 23% higher than the PBZ+GA 3 treatment. PBZ also significantly promoted xylem development in tuberous root of radish. In contrast, the GA3 treatment inhibited tuberous root growth and enhanced shoot growth in plants. Furthermore, mass spectrometry assay confirmed the absence of gibberellins in paclobutrazol-treated plants, whereas auxin was found in all treatments. Our study provides the first evidence on the applicability of PBZ in root size expansion of radish plant.

“…Intercropping shade-tolerant crops with trees is a viable strategy for increasing the utilization efficiency of arable land to meet the needs of an ever-growing human population. Potato (Solanum tuberosum L.) is a shade-tolerant food crop [22] that is commonly intercropped with trees in tropical and sub-tropical regions where there are high levels of solar irradiance. In these regions, shading has been shown to have minimal effect on potato tuber yield [22][23][24][25].…”

Crop production must increase substantially to meet the needs of a rapidly growing human population, but this is constrained by the availability of resources such as nutrients, water, and land. There is also an urgent need to reduce negative environmental impacts from crop production. Collectively, these issues represent one of the greatest challenges of the twenty-first century. Sustainable cropping systems based on ecological principles, appropriate use of inputs, and soil improvement are the core for integrated approaches to solve this grand challenge. This special issue includes several review and original research articles on these topics for an array of cropping systems, which can advise implementation of best management practices and lead to advances in agronomics for sustainable intensification of crop production.
