“…Tomato is one of the most popular and widely grown vegetables in the world. The first reason for this is that tomatoes are beneficial to our heath and are good sources of provitamins, carotene, and vitamin C. The second reason is that tomatoes are particularly rich sources of lycopene, which is a very powerful antioxidant and helps prevent the development of many forms of cancer [9][10][11][12]. Hence, this vegetable is gaining importance in both developing and developed countries, and efforts are being made to improve the quality and quantity of tomato production [13][14][15].…”

The water shortage in China, particularly in Northwest China, is very serious. There is, therefore, great potential for improving the water use efficiency (WUE) in agriculture, particularly in areas where the need for water is greatest. A two-season (2012 and 2013) study evaluated the effects of irrigation and fertilizer rate on tomato (Lycopersicum esculentum Mill., cv. “Jinpeng 10”) growth, yield, and WUE. The fertilizer treatment significantly influenced plant height and stem diameter at 23 and 20 days after transplanting in 2012 and 2013, respectively. As individual factors, irrigation and fertilizer significantly affected the leaf expansion rate, but irrigation × fertilizer had no statistically significant effect on the leaf growth rate at 23 days after transplanting in 2012. Dry biomass accumulation was significantly influenced by fertilizer in both years, but there was no significant difference in irrigation treatment in 2012. Our study showed that an increased irrigation level increased the fruit yield of tomatoes and decreased the WUE. The fruit yield and WUE increased with the increased fertilizer rate. WUE was more sensitive to irrigation than to fertilization. An irrigation amount of 151 to 208 mm and a fertilizer amount of 454 to 461 kg·ha−1(nitrogen fertilizer, 213.5–217 kg·ha−1; phosphate fertilizer, 106.7–108 kg·ha−1; and potassium fertilizer, 133.4–135.6 kg·ha−1) were recommended for the drip fertigation of tomatoes in greenhouse.

“…Diuron is absorbed quickly through plant roots, translocates through the xylem and phloem to leaves, and leads to lipid peroxidation, resulting in loss of chlorophyll (Moncada, 1998). Symptoms of yellowing and cupping of tomato leaves have occurred within five days after treatment of Glufosinate ammonium into soils (You and Barker, 2004), indicating the significant adverse impacts of the soil application of the herbicide on plant chlorophyll content. The root growth of nursery plants of tea cultivar TRI 4046 was visually the best visual in the untreated control.…”

The weed control potential of Artemisia vulgaris in tea lands has been reported. This study evaluated the non-target effects of the aqueous leaf extracts of A. vulgaris at 25, 50, 75 and 100 g/L (soilapplied, 40 ml/pot) on the growth of 7-months-old nursery tea plants (TRI 4006 and 4046) grown in black polythene bags with 1 kg topsoil. For comparison, commercial herbicides with different modes of action, i.e. Glyphosate, Diuron, MCPA, Pelargonic acid, Pine oil and Glufosinate ammonium, were soil-applied at recommended dosages, with distilled water as the control. Experiments were done in CRD with five replicates, with one plant/replicate. Leaf greenness (SPAD meter) at 20 days after treatment (DAT), visual observations of root growth, and shoot and root dry weights/plant were measured with destructive sampling at 30 DAT. Artemisia leaf extracts did not show significant negative impacts on the aboveground parameters of the tea plant compared to the control. The highest phytotoxicity on nursery tea plants was observed with MCPA (root cell damage; 100% plant mortality). The SPAD readings showed significant leaf chlorosis in TRI 4006 and TRI 4046 with Diuron and Glufosinate ammonium, compared to the control, Artemisia extracts, Pelargonic acid and Pine oil. Poor root growth with lesions was observed with 100 g/L Artemisia leaf extract but at a comparatively low degree to that of herbicides. As the non-target effects of A. vulgaris on tea plants were relatively lower, further studies are warranted to determine an effective dosage for weed control with minimum impact on tea plants and the environment.

“…The chemical structure of glufosinate-ammonium is shown in Figure . As one of the three major herbicides in the world, GLA has broad application prospects due to its advantages of high efficiency, low toxicity, and broad spectrum. − The mechanism of action of GLA is to irreversibly inhibit plant glutamine synthetase (GS), which can cause plant nitrogen metabolism disorder and inhibit plant photosynthesis, and ultimately lead to plant death. − …”

To separate and purify glufosinate-ammonium (GLA) and NaCl during the production of GLA, the solid−liquid equilibrium of GlA-NaCl-H 2 O system at 278.15, 313.15, and 333.15 K and the solid−liquid equilibrium of GlA-NaCl-H 2 O/CH 3 OH system at 333.15 K were measured by the isothermal dissolution method. The equilibrium solid phases were determined and characterized by Schreinemaker's wet residue method and X-ray diffraction. The results show that the phase diagram contains one invariant point, two univariate curves, and two single-salt crystallization regions corresponding to GLA and NaCl, respectively. Moreover, the influence of temperature and solvent on the thermodynamic properties of the GLA-NaCl system was investigated. It was found that temperature has little influence on the thermodynamic solubility and crystalline phase area of the GLA-NaCl system, while the solvent effect has an apparent influence. A fraction crystallization technology coupling evaporation crystallization and antisolvent crystallization was proposed to extract NaCl and GLA from a GLA and NaCl mixed solution.
