A pot experiments was conducted to study the possible role of melatonin (50 µM or 100 µM) alone or in combination with Basagran herbicide at recommended dose or ½ recommended dose in reducing the deleterious effect of weed associated with Vicia faba plants. Results show that all applied treatments significantly reduced the weed dry weight at 45 DAS and at harvest accompanied by significant increase in growth parameters of bean plants (at 45 DAS), all components of photosynthetic pigments, seed yield/plant and its components  relative to unweeded treatment. It is obvious that herbicide at recommended dose was more effective than herbicide at ½ recommended dose. Similarly, melatonin at 50 µM was more effective than melatonin at 100 µM. It is worthy...

Amino acids (bio-stimulants) are considered as cheap and biodegradable chemicals that increased yield and agronomic performance of several crops. A field experiment was conducted at the experimental station of National Research Centre, Nubaria district El-Behera Governorate-Egypt, during two winter seasons. Grains of two wheat cultivars (Misr 3 and Sids 12) were soaked with proline at 5 or 10 mM for 12 hours and dried at room temperature before sowing to study the effect of proline treatments on the performance and quality of wheat plants grown under sandy soil conditions. Data show that performance of Misr 3 cv grown under the conditions of sandy soil was more better than Sids 12 cv. Moreover, proline treatments at both concentrations caused significant...

Two field experiments were conducted during two successive seasons (2014/2015 and 2015/2016) at the Experimental Station of National Research Centre, Nubaria district, Beheira Governorate, Egypt, to study the effect of foliar treatment of quinoa plants with trehalose (Tre) (100µM and 500µM) on growth, photosynthetic pigments, seed yield quantity & quality, in fever of nutritional and antioxidant compounds in the yielded quinoa seeds which subjected to water deficiency (skipping two irrigation times at 50 & 60 days after sowing). Water deficiency caused marked decreases in quinoa plant growth parameters (shoot height, fresh and dry weights of shoot/plant) and photosynthetic pigments with marked increases in root growth parameters (root length, fresh...

The physiological effect of melatonin, IAA and their precursor (tryptophan) as seed priming on quantity and quality of chickpea plants was investigated during two growing seasons of 2013/2014 and 2014/2015 under sandy soil conditions at the Research and Production Station, National Research Centre, Nubaria Province, Behaira Governorate, Egypt. Data show that melatonin treatments showed the most pronounced effect on vegetative growth parameters followed by IAA and tryptophan treatments. The highest significant increase in dry weight of shoot/plant was achieved by melatonin treatments at 0.5 and 1.0mM. Moreover, melatonin treatments at 0.25 and 0.5 mM were the most pronounced treatments caused the highest significant increase in total photosynthetic pigments...

Ascobin had a promotion effect on growth and active constituents’ compounds of various plants under normal and stressed conditions. The physiological response of sunflower plant to foliar application of ascobin treatments (200,400,600 ppm) was investigated either under normal or salinity stressed conditions (5000 ppm NaCl solution) in pot experiments at the wire-house of the National Research Centre, Dokki, Cairo, Egypt. Data revealed that salinity stress caused significant decreases in shoot height, leaf area chlrorophyll b, carotenoids, total photosynthetic pigments, seed yield, yield components, oil and protein content of the yielded seeds relative to control. The decrease in oil percentage was more obvious by salinity than protein percentage. Since...

Two field experiments were conducted in two successive seasons, 2015 and 2016, at the experimental farm of the National Research Centre at Nubaria, Egypt, during summer seasons to determine weed management can improve soybean competitiveness with weeds, thus helping to achieve its yield potential. The experiment included three soybean cultivars ( Giza 111, Giza 21 and Crawford) and six weed control treatments, including oxadiargyl, butralin, metribuzin, bentazone + clethodium, two hand and a nonweeded treatment (control). Great reduction in dry weight of broadleaved, grassy and total weeds after 60 and 90 days from sowing was noticed in the plots cultivated with Giza 111 cultivars. Also, Giza 111 cultivars markedly produced greater plant height, SPAD, NAR,...

Two pot experiments were carried out during two successive winter seasons of (2016 / 2017) and (2017 / 2018) at the green house of National Research Centre (NRC), Giza, Egypt. The experiments were conducted to compare the allelopathic effect of Beta vulgaris (shoot and root aqueous extracts at 3, 6, 9%) to chemical herbicides (clodinafop-Propargyl and Basagran at recommended dose (140 g/fed and 1.5 l/fed, respectively) in controlling weeds (Phalaris minor and Malva parviflora) associated with Lupinus albus plants. Results showed that all applied aqueous extracts caused reduction in two weeds biomass under investigation. Meanwhile, root aqueous extract was more effective than shoot aqueous extract in controlling weeds. It is worthy to mention that phenolic...

Two field experiments were conducted during the winter seasons of 2014/2015 and 2015/2016 at the agricultural experimental station of the National Research Centre, Nubaria, Egypt. Field evaluation of the efficiency of weed-control treatments (unweeded, oxadiargyl, metribuzin and two hand hoeing) and bio-stimulants levels (folic acid at the rate of 10, 20 and 30 mg/L, and seaweed extract 100, 200 and 300 mg/L) and their interactive effects on faba bean growth, yield, yield attributes and chemical composition of seeds. Two hand hoeing achieved the highest weed depression expressed in the lowest dry matter of broadleaved, narrow-leaved and total weeds. Also, two hand hoeing was the most superior treatment in increasing plant height, shoot dry weight, leaf...
