“…It was revealed that the use of mulching improved the soil quality, soil moisture content, and microbial activities [29]. Improving the quality of the soil enables the plant to absorb its nutrient requirements from the soil and provides better growth and development of roots, which ultimately increases the number of roots [1][2][3][4]29]. The findings of the current study are in agreement with those of Sun [6,8,46].…”

“…Agricultural waste has increased dramatically in recent years due to the increase in agricultural production and thus the burden has increased on environmental scientists to devise innovative methods to recycle the agricultural waste [1,2]. Converting the agricultural waste into organic fertilizers is an ideal solution to reduce environmental problems and at the same time increase the soil fertility [3,4].…”

Adoption of suitable organic fertilizers and soil mulching are useful tools to enhance soil quality, which will inevitably lead to improved growth and yield of crops. Little is known about the soil organic amendments and Azolla (Azolla pinnata) under soil organic mulching on the growth and yield of squash plant (Cucurbita pepo L.). A comparative study mainly focused on the impacts of organic fertilizer treatments on soil fertility and squash growth under wheat straw mulch was conducted on wooden boxes filled with silty loam soil. Wheat straw, as an organic mulch, and five organic-fertilization treatments were added to the soil. Wheat straw with a size of <2 cm was added to the soil surface with a 2 cm thickness. The fertilization treatments were: control (CO), chemical fertilizer (CF), compost (CT), vermicompost (VC), and dry Azolla (DA). Wheat straw mulch had positive effects on the soil properties, growth, and yield. The maximum fruit yield was obtained from the soil fertilized with DA under wheat straw mulch, while the lowest one was found in the control without mulching. Azolla and organic fertilizers showed a remarkable superiority over the mineral fertilization in increasing the soil fertility as well as the growth and quality of squash fruits; this superiority increased under the wheat straw mulching system. The application of recommended mineral fertilization (CF), compost (CT), vermicompost (VC), and dry Azolla (DA) under wheat straw mulch increased the soil available-N by 2, 20, 12, and 29%, respectively, above the control (CO), while these organic fertilizers without mulching increased the soil available-N by 11, 32, 26, and 48%, respectively. The production of vegetable crops such as squash plants requires the addition of organic fertilizers and mulching to increase yield and quality of fruits.

“…The selected plants were placed in the plant growth chamber under normal growth conditions (25 ± 1 • C, 60 ± 5% relative humidity, 12 h photoperiod with a PPFD of 250 µmol/(m 2 •s)). The plants were supplied with water and nutrient solution (50% Hoagland nutrient solution) [26]. The NP solutions used were prepared from a 1 g L −1 CH-NP stock solution: 1% (w/v) CH-NP solution was first prepared in 5% acetic acid (v/v) and, after stirring, the solution was diluted to 1:10 with deionized water.…”

Exposure of banana plants, one of the most important tropical and subtropical plants, to low temperatures causes a severe drop in productivity, as they are sensitive to cold and do not have a strong defense system against chilling. Therefore, this study aimed to improve the growth and resistance to cold stress of banana plants using foliar treatments of chitosan nanoparticles (CH-NPs). CH-NPs produced by nanotechnology have been used to enhance tolerance and plant growth under different abiotic stresses, e.g., salinity and drought; however, there is little information available about their effects on banana plants under cold stress. In this study, banana plants were sprayed with four concentrations of CH-NPs—i.e., 0, 100, 200, and 400 mg L−1 of deionized water—and a group that had not been cold stressed or undergone CH-NP treatment was used as control. Banana plants (Musa acuminata var. Baxi) were grown in a growth chamber and exposed to cold stress (5 °C for 72 h). Foliar application of CH-NPs caused significant increases (p < 0.05) in most of the growth parameters and in the nutrient content of the banana plants. Spraying banana plants with CH-NPs (400 mg L−1) increased the fresh and dry weights by 14 and 41%, respectively, compared to the control. A positive correlation was found between the foliar application of CH-NPs, on the one hand, and photosynthesis pigments and antioxidant enzyme activities on the other. Spraying banana plants with CH-NPs decreased malondialdehyde (MDA) and reactive oxygen species (ROS), i.e., hydrogen peroxide (H2O2), hydroxyl radicals (•OH), and superoxide anions (O2•−). CH-NPs (400 mg L−1) decreased MDA, H2O2, •OH, and O2•− by 33, 33, 40, and 48%, respectively, compared to the unsprayed plants. We hypothesize that CH-NPs increase the efficiency of banana plants in the face of cold stress by reducing the accumulation of reactive oxygen species and, in consequence, the degree of oxidative stress. The accumulation of osmoprotectants (soluble carbohydrates, proline, and amino acids) contributed to enhancing the cold stress tolerance in the banana plants. Foliar application of CH-NPs can be used as a sustainable and economically feasible approach to achieving cold stress tolerance.

“…Drainage factor [10] such as water level condition up to 60 cm of channel is an important parameter. Meanwhile, the economic factors should be considered in peat land clearing [11] such as the profit [12]. Agricultural input at peatland is relatively costly in addition to environmental degradation hazard, especially as a result of land drainage that may increase CO2 gas emission [13].…”

This study aims to determine the main limiting factors in agricultural development on peat lands and the agricultural input to improve it. The study was conducted in peat land of the Sriwijaya Botanical Gardens, Bakung Ogan Ilir Village, South Sumatra, Indonesia. A detailed survey was designed based on a map scaling of 1: 5,000 and analyses of peat samples were carried out in the Soil Science Department Laboratory of Sriwijaya University. The Soil Map Unit (SMU) was then generated based on peat depth and its maturity. The indicator of agricultural food crops is corn. The results showed that the maturity of the peat was dominated by sapric, the depth was divided into two classes, namely 1.5-2m and >2m. The actual land suitability of the site was unsuitable (Nrc, nr) with the limiting factors, i.e. nutrient retention and root media. The limitation of nutrient retention was on low soil pH and low potassium. Whereas, Nitrogen and Phosphorus content were considered as high and medium. By giving agricultural input, the potential land suitability class improve to S3rc (less suitable) with the limiting factor including peat depth. There were some areas considered as permanently unsuitable (Nrc) due to peat depth. Drainage control is essential management to ensure crop water availability.
