This work was carried out in a Private Farm at Kofor Negm Village, Elibrahimia District (N, 31° 33′ 47.11″ E 6.23″ 43′ 30°), Sharkia Governorate, Egypt, during the two consecutive winter seasons of 2021/2022 and 2022/2023 to study the influence of different potassium fertilizer sources [potassium citrate (36.5%K2O), potassium thiosulphate (35% K2O) and potassium silicate (18% K2O) as foliar spray], different intercropping systems (sole crop of each components as control, 1: 1, 1: 2, 2: 1 and 2: 2 as row ratio of coriander: garlic) and their combination treatments on growth parameters, yield components and chemical constituents of garlic crop. The findings showed that, when coriander was intercropped with garlic at a ratio of 1: 2 as opposed to sole crop and the other intercropping systems under study, the highest benefits were obtained in terms of growth (plant height, number of leaves per plant, and total plant dry weight), yield components (bulb diameter, number of cloves per bulb, and average bulb weight), as well as N, P, K, and total carbohydrates percentage in garlic cloves. Compared to the other sources of potassium under study, potassium silicate application as a foliar spray four times/seasons produced a higher bulbs yield per feddan. The results indicated that, the development and production of the garlic crop can be maximized by using an intercropping system of 1 ridge of coriander: 2 ridges of garlic and potassium silicate application.

A field experiment was conducted at a private farm in Taha El-Marg Village, Diarb Negm District, Al Sharqia Governorate, Egypt during the two consecutive winter seasons of 2020/ 2021 and 2021/2022. This experiment was done to study the effect of intercropping systems between caraway: garlic at different row ratio (sole crop of each as control, 1: 2, 2: 1 and 2: 2, respectively), different potassium rates (0, 25, 50 and 75 kg K2O/feddan) and their combination on growth and yield of caraway and garlic plants. Main plots consisted in the intercropping systems and the subplots were constituted by the potassium fertilization rates. Alternating two rows of caraway with two rows of garlic significantly increased plant height, number of branches per plant, plant fresh weight, number of umbels per plant and fruit yield per plant compared to sole caraway planting. Also, using 1: 2 intercropping system gave the highest values regard plant height, plant fresh weight and bulb fresh weight compared to sole garlic planting. Moreover, the highest potassium fertilization rate (75 kg K2O /feddan) gave the highest values in growth traits and yield components of caraway and garlic crops compared to control. Sole crop of caraway and garlic significantly recorded the highest values of fruits and bulbs yield per feddan compared to intercropping systems under study. In general, the combination between intercropping system and potassium affected growth and yield components of both crops and the best treatment in this regard was 2: 2 system for caraway and 1: 2 for garlic and 75 kg K2O/feddan.

A filed experiment was carried out at a private farm located at Qaha District, Qalubayia governorate, Egypt, during the two successive summer seasons of 2018 and 2019 to evaluate growth and productivity of seven new dry bean genotypes (DB-2-435, DB-5-485, DB-5-486, DB-5-487, DB-5-489, DB-7-4 and DB-7-31) in additional to three commercial cultivars (Giza 3, Giza 6 and Nebraska) under different plant densities, i.e., 5 cm one row, 10 cm one row, 5 cm 2 rows and 10 cm 2 rows/ridge. These treatments were arranged in a split plot in a randomized complete block design with three replications. Plant densities were randomly distributed in the main plot and genotypes were randomly arranged in the sub plot. As average two seasons, sowing seeds of genotypes DB-5-485, DB-5-487, DB-5-489 at 10 cm on one side increased number of branches/plant, leaf area/plant, dry weight/plant and total chlorophyll in leaf tissues, followed by the interaction between sowing at 10 cm on one side and Nebraska cultivar regarding total chlorophyll in both seasons. In general, the interaction between sowing at 10 cm on one side and Nebraska cultivar or genotype DB-5-485 increased number of seeds/pod, yield/plant in both seasons. Respecting total yield, the interaction between sowing at 5 or 10 cm on two sides and Nebraska cultivar or the genotype DB5-485 gave the highest values of total yield /fed., however, the interaction between sowing at 5 cm on one row and DB-5-486 genotype gave the lowest total yield/fed. (0.781 ton/fed.) as average of two seasons. [ABSTRACT FROM AUTHOR]

Pots experiment was designed in two summer successive seasons of 2017 and 2018 at the wire house of the Agric. Bot. Dept., Fac. Agric. Zagazig Univ., Sharkia Governorate, Egypt. Common bean plants cv. Giza 3 were foliar sprayed with different concentrations of humic acid, proline, naphthalene acetic acid and distilled water (as a control) under sea water salinity levels, i.e. 1000, 2000 and 3000 ppm and tap water (500 ppm) as a control, to examine its effects on growth, photosynthetic pigments, proline content, yield and leaf anatomy of common bean plants. Results revealed that most studied traits, i.e., plant height, number of leaves/plant, leaf area, fresh weight of roots, stems and leaves, photosynthetic pigments (chlorophyll a, chlorophyll b, chlorophyll a+b and carotenoids) and yield expressed as number of pods/plant, number of seeds/pod, number of seeds/ plant, 100-seed weight and length of pod as well as leaf anatomical parameters. Most aforementioned features were significantly decreased with increasing sea water levels up to the highest level (3000 ppm) comparison with control (tap water). On the contrary, proline content in leaves was increased with increasing salinity levels up to 3000 ppm. On the other hand, spraying common bean plants with humic acid at 2 and 4g/L, proline at 50 and 100 ppm and naphthalene acetic acid at 25 and 50 ppm had a positive significant effect in most studied traits compared to control (distilled water). In general, the most favorable treatments were foliar spray common bean plants with humic acid at 2g/L followed by proline at 100 ppm then naphthalene acetic acid at 25 ppm, respectively compared to control (distilled water). It could be concluded that spraying of humic acid, proline and naphthalene acetic acid mitigate the harmful effect of sea water salinity on common bean plants and the best treatment was interaction between irrigation with tap water or sea water at 1000 ppm and spraying by humic acid at 2 g/L.
