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.

To enhance growth and productivity of roselle plant, two field experiments were done during the two consecutive summer season of 2019 and 2020 at Experimental Farm (Ghazala Farm), Faculty of Agriculture, Zagazig University, Egypt. This study included different pinching time treatments (after 4, 6, 8 and 12 weeks from sowing date) as the main factor and potassium fertilization rate (0.0, 25, 50 and 75 kg K2O/ feddan) as sub-factor as well as their combinations to improve growth, yield, anthocyanin content and some chemical contents of Hibiscus sabbdariffa plant. Results could be summarized as follow: The longest roselle plants were recorded with the control treatment (pinched after 4 weeks from sowing date), whereas pinching after 12 weeks from sowing date increased number of branches/plant. Also, apical bud pinching after 12 weeks from sowing date recorded the highest number of fruits per plant, dry sepals yield/plant and per feddan. Delaying pinching date from 4 to 8 weeks gradually increased anthocyanin content. In addition, total chlorophyll content as well as total carbohydrates, total nitrogen, total phosphorus and potassium percentages were increased with delaying pinching date especially after 12 weeks, in most cases. Potassium fertilization rate at 75 kg per feddan recorded the highest values of growth, yield components and the chemical constituents with significant differences between this rate and the other rates under study. Generally, the combination treatment between pinching after 12 weeks from sowing date and 75 kg potassium fertilization rate had significant effect in most parameters compared to the other combination treatments during both seasons.

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.

Broccoli is a popular vegetable throughout the world and contains important nutritional features. This study was conducted to evaluate the effect the fertilization with different phosphorus sources (i.e., soil application of rock phosphate (RP) at 428 kg ha−1, calcium superphosphate (CSP) at 670 kg ha−1, phosphoric acid (PA) at 126 L ha−1 and monoammonium phosphate (MAP) at 334 kg ha−1) combined with biofertilizers (i.e., inoculation with phosphorin or mycorrhiza) on plant growth aspects, antioxidants enzyme activity, chemical constituents, yield and quality of broccoli leaves and heads (Brassica oleracea var. italica Plenck). The experiment was performed according to the randomized complete block design with three replications (n = 3), for two growing seasons (2018–2019) at the experimental farm of Benha University, Egypt. The obtained results showed that the highest values of plant height, leaf area, fresh and dry weight of leaves/plant, head weight and diameter, and the highest yield of heads ha-1 were recorded in plants that received MAP fertilizer and were inoculated with mycorrhiza. On the other hand, the highest value of head length, total carbohydrate and total soluble solids (TSS) content were observed in plants fertilized with PA and inoculated with mycorrhiza. The highest leaf nitrogen % and head ascorbic acid content, as well as the lowest head total phenol content were recorded in plants supplemented with MAP fertilizer and inoculated with mycorrhiza. Moreover, broccoli plants fertilized with PA and inoculated with mycorrhiza showed promising results in terms of phosphorus, potassium and total carbohydrate content, antioxidant activity and dehydrogenase activity. In conclusion, phosphorus may affect plant growth, yield and chemical parameters in broccoli plants depending on the fertilizer source, while inoculation with mycorrhiza may also have a beneficial impact on these parameters.

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.

Effect of nitrogen and bio-fertilizer on growth and productivity of hybrid rice (cv. PHB 71) was assessed during dry seasons of 2017 and 2018 at Research Farm of BCKV under new alluvial zone of West Bengal. The experiment was laid out in factorial randomized block design with 12 treatment combinations having 4 levels of N and 3 types of bio-fertilizer replicated thrice. Application at 180 kg N/ha produced tallest plants at 90 DAT with maximum LAI (60 DAT), DMA (90 DAT), tillers/hill (90 DAT) and CGR (30-60 & 60-90 DAT). The same N rate resulted in highest panicles/m2, panicle length, panicle weight, filled grains/panicle and 1000-grain weight. A decrease in N dose from 180 to 150 kg/ha caused reduction in all those yield components; however, the variation was non-significant except for number of panicles/m2. Maximum grain yield, straw yield and harvest index was also achieved with 180 kg N/ha accounting 120.1, 34.9 and 32.8% more than the values obtained with zero-N; however, it was statistically at par with the yields and HI obtained with 150 kg N/ha. The Azospirillum application increased all the growth parameters, yield components and yield of hybrid rice over other tested bio-fertilizers (Azospirillum > PSB > K mobilizer), accounting 5.9 and 8.8% more than the yields obtained with PSB and K mobilizer. The interaction of N and bio-fertilizer exerted significant effect on growth attributes but failed to record any significant variations in yield components and yield of hybrid rice. The maximum economic benefit was achieved with combined application of 180 kg N/ha and Azospirillum.
