Beet production using vermiculite incorporated with Dystrophic Red Latosol (Oxisol)

Vermiculite is an expansive material that can be used for crop production. However, information about the use of vermiculite in vegetable production is scarce. Thus, this study's objective was to evaluate the effects of vermiculite levels incorporated into the soil (Red Latosol Dystrophic) for beet (Beta vulgaris L.) crop production. The experiment was performed during spring using the beet cultivar 'Early Wonder Tall Top' and 0, 2, 4, 6, 8, and 10 t∙ha-1 of vermiculite incorporated into the soil before seedling planting. The increase of the vermiculite doses caused a linear decrease of the fresh root and leaf weight. The yield reductions were due to the great water holding capacity of the vermiculite and the consequent high incidence of cercosporiosis (Cercospora beticola Saac).

Maize (Zea mays L.) is the most important consuming cereal crop in the world after rice and wheat. This requires an understanding of various management practices as well as conditions that affect maize crop performance. Water deficit stress during crop production is one of the most serious threats to crop production in most parts of the world and drought stress or water deficit is an inevitable and recurring feature of global agriculture and it is against this background that field study of crops response to water deficit is very important to crop producer and researchers to maximize yield and improve crop production in this era of unpredicted climatic changes the world over.A pot experiment was carried out to determine the effects of water deficit on growth and yield formation of maize. Two maize cultivars were used Xundan20 and Zhongdan5485. Three levels of soil water content were used in two stages of water control levels at two stages of the maize plant development1. The JOINTING STAGE: A. CONTROL (CK) soil water content: from 70% to 80% of soil water holding capacity at the field, soil water content: from 55% to 65% of soil water holding capacity at the field, soil water content: from 40% to 50% of the Soil water holding capacity at the field.2. The BIG FLARE PERIOD: A. CONTROL (CK) soil water content: from 75% to 85% of soil water holding capacity at the field, soil water content: from 58% to 68% of soil water holding capacity at the field, soil water content: from 45% to 55% of the soil water holding capacity at the field.This research mainly studied the effects of water deficit on physiological, morphology and the agronomical characteristics of the maize plant at the different water stress levels.The importance of these results in this experiment will enable plant producers to focus and have a fair idea as to which stage of the maize plant’s development that much attention must be given to in terms of water supply.

Water Holding

Greenhouse technology is becoming an indispensable and feasible solution for modern crop production methods. Technological progress has reduced the impact of severe weather conditions on greenhouse crop yields in high temperature climate. Cooling and dehumidifying are the key to ensure the required temperature and humidity range inside the greenhouse. The purpose of this work is to evaluate the dehumidification technologies used in the agricultural industry. The theoretical and practical aspects of greenhouse cooling technology are shown: working principles, conditions and performance. The primary humidity control method utilized in greenhouses is evaporative cooling by using air’s water holding capacity. According to the experimental results, the quantitative analysis was carried out from the perspective of energy and cost, which demonstrated that the evaporative cooling fan-pad system was also an effective method of greenhouse cooling in humid climate. This work would provide technical support or the optimisation of the energy management of greenhouses in humid climates and recommend the mathematical model in future work.

Water Holding

Container-grown nursery crops generally require daily irrigation applications and potentially more frequent applications during the hottest part of the growing season. Developing management practices that make more efficient use of irrigation water is important for improving the sustainability of nursery crop production. Biochar, a byproduct of pyrolysis, can potentially increase the water-holding capacity and reduce water and nutrient leaching. In addition, the development of sensor-based irrigation technologies has made monitoring substrate moisture a practical tool for irrigation management in the nursery industry. The objective of this research was to determine the effect of switchgrass biochar on water and nutrient-holding capacity and release in container substrates of Buxus sempervirens L. × Buxus microphylla (‘Green Velvet’ boxwood) and Hydrangea paniculata (Pinky Winky® hardy hydrangea). Containers were filled with pine bark and amended with 0%, 10%, or 25% volume of biochar. Plants were irrigated when the volumetric water content (VWC) reached the water-buffering capacity set point of 0.25 cm3·cm−3. The sensor-based irrigation in combination with the low cost biochar substrate amendment increased substrate water-holding capacity and reduced irrigation requirements for the production of hydrangea, a high water use plant. Biochar application rate influenced irrigation frequency, which likely affected plant biomass for hydrangea, but boxwood dry weight was unaffected by biochar rate. Total irrigation applied was decreased by 32% in 10% biochar treatment without reducing hydrangea dry weight. However, in the 25% biochar treatment, total irrigation applied was reduced by 72%, whereas dry weight decreased by 50%. Biochar application reduced leaching volume and leaching fraction in both plants. Leachate analysis over the course of the 8-week experiment showed that the average mass of phosphate (PO4), potassium (K), and total carbon was greater in the leachate from containers that received 25% biochar compared with those receiving 0% or 10% biochar for both plant species. For hydrangea, mass of total nitrogen (TN) and nitrate (NO3) in leachate was not significantly affected by increasing the biochar rate. However, for boxwood, the mass of NO3 and TN was greater in the 25% biochar treatment leachate, whereas the mass of ammonium (NH4) was unaffected. In hydrangea, total nutrients lost from the containers was lower in biochar-amended containers (both 10% and 25% biochar) because of receiving a lower total volume of water. Amendment with biochar also affected concentration of phosphorus (P) and K, with the highest concentration in both leaf tissue and substrate from the 25% biochar application rate.
