Ernesto Moya-Elizondo 2. Shade cloth is commonly used to reduce incident light in apple Malus domestica [Suckow] Borkh. Nevertheless, this technology can generate changes in plant physiology that affect tissue nutritional composition and cause fruit nutritional disorders.
Averaged results for the three seasons showed that shade cloth increased Mg, Mn, and Zn concentrations in leaves by 0. Bitter pit incidence was not affected by shade cloth values between 0. In conclusion, the use of shade cloth in apples did not affect bitter pit incidence, but it caused some changes in leaf and fruit nutritional concentration. Fruit production currently includes modern management practices and high-technology production systems, which are associated with the use of cover crops for weed control, integrated pest and disease management, high density planting, pedestrian orchards, mechanical high-pressure irrigation systems, and the use of netting or covers to protect against excessive radiation.
The combination of modern management practices and high-technology systems allows profitable production and fruit quality according to customer requirements. This high-technology system has also been used in vegetable crops such as tomato Sandri et al.
The use of shade cloth in agricultural production and in specific orchards has a protective function against excessive radiation on the fruits, and this technology could mitigate adverse effects of climate change on fruit trees Demchak,Bassett et al. Ban et al. Du et al.
In addition, Kim et al. Those changes could also affect the nutritional composition in leaves and other structures such as fruits. Reported benefits of shade cloths include improved blueberry fruit quality Lobos et al. Shade cloths used in orchards and on horticultural crops can affect both fruit and leaf nutrient concentrations because greater or lesser light incidence can alter transpiration rates, which can generate an increased or decreased concentration of some nutrients and organic compounds in cultivated plants.
Changes in starch content associated with variations in the inorganic P Pi concentration in tomato leaf vs. Mohotti and Lawlor found that shade application affected N concentration in tea leaves, so that plants treated with heavy and medium shade cloth had higher leaf N content mean 2. Beech Fagus sylvatica L. Leaf and fruit nutrient concentrations can be affected by different factors. For example, variations over time associated with the age of leaves and fruits and nutrient mobility to fruits during growth have been demonstrated in kiwifruit Smith et al.
There is no scientific information that associates changes in the nutrient concentration in tissues of different ages with the incident light level. De Freitas et al. Physiological problems of fruits at postharvest are usually associated with nutrients related to Ca deficiency; several authors have found that it is not sufficient to determine the Ca concentration Le Grange et al.
Le Grange et al. Von Bennewitz et al. In addition, de Freitas et al. Considering that different levels of incident light or shade on the tree could affect tissue nutritional concentration and that there is not enough information reported for apples de Freitas et al.
Soil physicochemical properties were analyzed using methods described by Sadzawka et al. Soil pH was measured in a soil:water solution at aSoil organic matter was measured by the Walkley-Black wet digestion method. Available P in the soil sample was determined with 0. Boron was determined by colorimetry in a hot water solution , Unicam, Ilminster, UK.
Soil texture was analyzed by the Bouyoucos hydrometer method. Soil physicochemical properties evaluated in the experiment were not limitations for apple production according to standards Palmer and Dryden, Table 2 ; therefore, no chemical amendments were applied prior to starting the experiment.
The net was installed 4 m from the ground on 15 November with 2- to 3-cm diameter fruits and removed on 25 March of each growing season before harvest. Each treatment consisted of five replicates. Table 1 Climatic characteristics of the experimental site for the three evaluated seasons. Table 2 Soil chemical properties at 0. All apple trees were irrigated with a double line drip irrigation system and drippers with 2 L h -1 flow were located every 50 cm from the trees.
Orchard aisles were covered with vegetation consisting of native species, grasses, and legumes. The fertilization scheme is shown in Table 3 ; phosphoric acid, calcium nitrate, magnesium sulfate, and urea fertilizers were applied by fertigation. Phytosanitary sprays were normal for a commercial apple orchard, emphasizing controls of apple scab Venturia inaequalis , powdery mildew Podosphaera leucotricha , nectria canker Nectria galligena , and moldy core caused by Alternaria spp.
Fruit total yields were 58, 61, and 56 Mg ha -1 for the , , and seasons, respectively, there were no differences between the area with and without shade cloth, and fruit load per plant was adjusted by manual thinning to to fruits per tree.
Sample leaves were collected from each treatment and replicate on 30 January in each season. Each leaf sample was collected from the fruitless spurs located at crown height on both sides of the rows 1. The methodologies were those indicated by Sadzawka et al. Table 3 Fertilization management during the experiment.
The field experiment was conducted using a randomized complete block design with two treatments and five replicates 10 experimental units. Each row of trees 60 m long with a total area of m 2 was defined as an experimental unit.
An ANOVA was performed to establish differences among treatments given a split plot design in which the main plot was the season and the split plot was shade cloth treatments. Table 4 Significance analysis of the effect of treatments and interactions on leaf and fruit nutrient concentrations.
The leaf N concentration fluctuated between 1. The leaf P concentration varied between 0. The leaf K concentration ranged from 1. Meanwhile, the Ca concentration varied between 1. The leaf Mg concentration values fluctuated between 0. The leaf S concentration varied between 0. The leaf Fe concentration ranged fromThe leaf Mn concentration fluctuated betweenThe leaf Zn concentration values varied betweenThe leaf Cu concentration ranged from 6.
The leaf B concentration values varied betweenFinally, the leaf Na concentration fluctuated betweenThe fruit N concentration fluctuated betweenThe fruit P concentration values varied between 9. The fruit K concentration ranged fromThe fruit Ca concentration values fluctuated between 4. The fruit Mg concentration fluctuated between 4. The fruit S concentration values varied between 3. Overall, fruit nutritional relationships showed differences between seasons and the effect was erratic Table 6.
Relationship between bitter pit incidence and fruit nutritional concentrations. Values fluctuated between 0. Lines over the bars indicate standard error. Figure 1 Bitter pit incidence in apple fruits with and without shade cloth management over three consecutive seasonsIn addition, changes in apple leaf nutrients can also be associated with different crop loads, as reported by Brendon et al.
Production was very similar during the three evaluated seasons. Results for macronutrients in this study showed that the N concentration was similar, the K concentration was lower, and the P, Ca, and Mg concentrations were higher compared with findings by von Bennewitz et al. These differences in concentration, based on information published in the literature, can be a response to soil physicochemical properties Sparrow and Uren, , fungicide or cupric bactericide application management, and soil or leaf nutrient applications.
For example, mancozeb manganese ethylene-bis-dithiocarbamate complex with zinc salt , applied six to eight times during fruit and leaf development to control Venturia inaequalis , can increase both the Mn and Zn concentrations. The increased Mg concentration when using shade cloth can be associated with higher chlorophyll activity and lower negative effect of direct light on this pigment Demchak,Increased Mn and Zn concentrations are associated with greater soil moisture conservation Navarro and Navarro, ; Sparrow and Uren,Shade cloth reduces moisture requirements associated with lower stomatal density Kim et al.
The results of the present study suggest that reference concentrations for Mg, Mn, and Zn nutrients in orchards managed with shade cloth could be higher than the standards used for conventional apples Fallahi et al. Sampling was conducted between 16 and 20 wk after bud break, from mid-January to mid-February in the Southern Hemisphere. However, more specific studies are required to determine the appropriate leaf nutritional range in apples.
The differences in fruit nutritional concentration between seasons in the present study have also been reported by other authors Nava and Dechen, ; Brendon et al. The nutritional relationship in apple fruits has usually been in the range indicated by Lepe to reduce the risk of bitter pit incidence. The lack of correlation between the apple fruit nutritional status and bitter pit incidence has also been reported by other authors Le Grange et al.
The nutritional concentration in fruits was affected by shade cloth and there was an interaction with the seasons. In general, shade cloth decreased the K, Mg, and S concentrations byBitter pit incidence was affected by the season under evaluation, but this abiotic disorder was not affected by the shade cloth treatment.

Saffron Crocus sativus L. The production of saffron is limited by several factors, including weed infestation, which causes damage to the crop in terms of quantity and quality. However, little information is available on the different weed management strategies for saffron cultivation, as most of the strategies implemented are developed for large-scale and conventional agriculture. As a result, they are not applicable or affordable for organic or smallholder farmers, as is the case for saffron cultivation. The objective of this study is to compare the effectiveness of plastic mulching versus mulching in controlling weeds in saffron cultivation in the eastern region of Morocco. During the trial, which was conducted in , the parameters measured correspond, on the one hand, to morphometric measurements and determination of saffron stigma yield and, on the other hand, to the determination of density, dry biomass, and weed control capacity. Compared to the control, mulching reduced the population and dry biomass of the most formidable weeds such as Cynodon dactylon , Aster squamatus , Cyperus rotundus , and Convolvulus arvensis.

The disadvantages of the artificial light can effect our environment. The presence of light inhibits the production of melatonin, a hormone that induces sleep. Light at night, especially blue light, suppresses melatonin production [12, 9, 13]. Some studies indicate a link between artificial light and obesity as well. Effect of light on protoplasm: Though the bodies of most animals remain protected by some sort of body covering which save animal tissues from the lethal effects of solar radiations. Thereby, artificial light can delay the timing of the circadian clock and thus sleep.
