The Impact

Coriander (Coriandrum sativum, L.) is an important aromatic plant in Egypt. A current work was aimed to study the impact of nano-chitosan rates (0.0, 2 and 4 ml/l), glutamine acid concentrations (0.0, 25, 50 and 100 ppm) and their interaction treatments on growth, yield components as well as volatile oil and some chemical constituents of coriander plant. Two field experiments were conducted at Kafr El-Hamam Experimental Station of Agric. Res. Cen., ElSharkia Governorate, Egypt during 2018/2019 and 2019/2020 seasons. These experiments were based as a split-plot in randomized block design with three replications. The nano- chitosan rates were randomly arranged in the main plots, while, glutamine acid (Gln) concentrations were distributed randomly in the sub plots. Based on two years study it was found that most of nano-chitosan rates and glutamine acid concentrations proved to be superior and recorded higher values of coriander yield components over control. Application of nano-chitosan at 4 ml/l resulted higher values of coriander growth (plant height, branch number per plant and total dry weight), yield components (number of inflorescences per coriander plant, fruit yield per plant and per feddan), volatile oil production (volatile oil percentage, volatile oil yield per plant and per feddan) as well as chemical constituents (N, P, K and total carbohydrates percentages in fruits and total chlorophyll content in coriander leaves) over the lowest rate and control. The same trend in these characters of coriander was obtained when Gln acid was used as foliar spray at 100 ppm concentration compared to the other ones under study. In general, nano-chitosan at 4 ml/l interacted with Gln acid at 50 ppm recorded the highest values of yield components of coriander plants compared to the other interaction treatments under study.  Finally, this treatment gave the highest values in major constituents of volatile oil such as linalool, camphor, gamma- terpinene, geranyl acetate and alpha-pinene.

Potassium Fertilization

A split-plot experiment based on randomized complete block design (RCBD) with three replications was planned at Experimental Farm, Agriculture Faculty, Zagazig University, Egypt during the two consecutive seasons of 2018/2019 and 2019/2020. Aiming to study the effect of different potassium fertilization rate (0.0, 24 and 48 K2O kg/feddan) and different kaolin concentrations (0.0, 15, 30 and 45 g/l) as well as their combination treatments on growth parameters, yield components, fixed oil, and active ingredient. Results indicated that growth parameters (plant height, branch number/ plant and dry weight/plant), yield components (number of pods/plant, seed yield/ plant and /feddan) and chemical constituents (total chlorophyll, total nitrogen, potassium, total carbohydrates, mucilage and trigonelline content) were influenced by experimental factors. Furthermore, the highest rate of potassium fertilization recorded significant increase in these above parameters compared to control. In the same trend, the highest values in this concern of Trigonella feonum-graecum was observed with 30 or 45 g/l of kaolin compared to control. Moreover, applied 48 kg K2O /feddan was more efficient than 24 kg and control when combined with kaolin at 30 or 45 g /l, in most cases. Generally, this combination treatments seems promising in enhancing fenugreek growth and productivity under Sharkia Governorate conditions.

The response of cowpea cv. Cream 7 growth and productivity to potassium fertilization mixed with or without Nano mixture of micronutrients were studied during the summer of 2017 and 2018 seasons at Experimental Farm, Faculty of Agriculture, Zagazig University, Egypt. The experiment aimed to assessed the effect of potassium fertilization levels (0.0, 24, 48 and 72 kg K2O/Fed), Nano mixture of micronutrients rate (0.0, 0.50, 1.0 and 2.0 g/l) and their interactions on growth, seed yield, macronutrients concentration in shoot and seeds and seed quality of cowpea plants. Source of potassium levels was potassium sulphate (48-52% K2O). The used Nano mixture of micronutrients called "Magrow NanoMix" and it contained Fe (6%), Zn (6%), B (2%), Mn (5%), Cu (1%) and Mo (0.1%). These treatments arranged in a split-plot design with three replicates. The results referred to that fertilizing cowpea plants with potassium at 72 kgK2O/Fed. significantly increased cowpea growth (plant height, branch and leaf numbers per plant as well as branch, leaf and total dry weights/plant), yield components(pod diameter and length, hundred seeds weight, pod number/plant and seed yield/ plant and /Fed.) as well as chemical constituents (N, P and K percentages in each leaves and seeds as well as total carbohydrates and protein percentages in seeds, also, total chlorophyll content (SPAD) in cowpea leaves compared with control and the lowest levels under study. The same trend was achieved by using the highest rate of Nano mixture of micronutrients (2g/l) regarding the increase in most of abovementioned parameters of growth, yield and chemical constituents of cowpea compared with unsprayed plants (control). In general, application of potassium fertilization at 72kg K2O/ Fed. as soil application with Nano- mixture of micronutrients at 2g/l rate as foliar spray was recorded the best treatments for increasing all cowpea growth and seed yield components as well as N, P, K and carbohydrates percentage in seeds such as compared with control treatment (without using mineral potassium or Nano mixture of micronutrients) in growing season.
