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.

The saw-toothed grain beetle, Oryzaephilus surinamensis (L.) is an important pest of many stored product foods. The effect of insect infestation on four various of whole food kinds as semi-dry date, dry date fruits, white sesame and reddish yellow sesame seeds as well as four food kinds of crushed seeds (chickpea, corn, rice and groundnut) as compared with standard diet (wheat flour, crushed wheat and dry yeast powder at 5:5:1, respectively) was investigated in the laboratory of Plant Protection Department, Faculty of Agriculture, Zagazig University, Egypt. Insect parameters on the tested food kinds as regards to resistance were duration of developmental stages, number of F1 progeny, growth index and weight loss (%) after one month of storage. All tested parameters were significantly affected by food kinds except the duration of pupal stage in whole foods. The shortest mean insect complete developmental period was 19.85 days on standard diet, while the longest one was 29.18 days on whole reddish yellow sesame seeds and 35.05 days on crushed groundnut. Values of the growth index (GI) increased from 3.22 to 3.76 on whole reddish yellow sesame seeds and crushed chickpea, respectively compared to 4.64 on standard diet. The wet weight loss (%) ranged from 0.50 and 0.67% in whole sesame seeds (white and reddish yellow) and crushed groundnut, suscessively compared to11.17% in standard diet. The relative wet weight loss (%) in whole seeds reached its minimum (1.94%) in each of whole white and reddish yellow sesame seeds and reached its maximum (43.23%) in standard diet, while in crushed foods, the lowest value was 3.16% in crushed groundnut as compared with the standard diet which recorded the highest percent 52.76%. All tested foods either whole or crushed were infested with O. surinamensis and no completely immune food was found free from the insect infestation but the insect preferred crushed foods and some foods than another.

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.

This investigation was conducted at the, Experimental Farm, Faculty of Agriculture, Zagazig University, Sharkia Governorate, Egypt during 2016 and 2017 summer seasons to study the growth and forage yield of Pearl millet. The experiment was arranged in a split plot design with three replications. The treatments consisted of two cutting dates [early at 56 days after sowing (DAS), and late at 63 DAS for the 1st cut, and after 35 and 42 days from the 1st and 2nd cuts for the 2nd and 3rd cuts] respectively and three nitrogen (N) fertilizer levels viz. 15, 30 and 45 kg N/fad./cut. The results indicated that late cutting date significantly produced the highest growth values for each of plant height (238.2 cm), leaf area/plant (4970.2 cm2) and fresh forage weight (164.9 (g)/plant). Also, the highest fresh and dry forage yields (16.88 and 3.541 ton/fad), the highest total fresh seasonal yield (TFSY) and total dry seasonal yield (TDSY) 37.98 and 7.11 ton/fad., were as well recorded by late cutting in both seasons. Apparently, the highest obtained value of each studied growth traits and the forage yield during both growing seasons was achieved by increasing N fertilizer level up to the highest amount (45 kg N/fad./cut), followed by 30 and 15 kg N/fad./cut, respectively. The significant interaction effect between the two studied factors on forage yield indicated that the highest (TDSY) (7.607 ton/fad.) of pearl millet was obtainable at late cutting date under application of 45 kg N/fad./ cut. The results of the present study has concluded that, cutting at 63 DAS followed by 42 and 35 days interval for next cuts (three cuts) with application of 45 kg N/fad./cut is optimum for better growth and yield performance in pearl millet cultivar “Shandaweel 1” under the agro-climatic conditions of Sharkia Governorate in Egypt and similar areas.

The current study was conducted in order to assess nutritional knowledge and food behavior of osteoporosis among women in Sharkia Governorate, Egypt. Sources of information about osteoporosis and dietary intake of participants were also evaluated. This research was a descriptiveanalytical study. Data was collected using a questionnaire that was distributed to 300 women from Sharkia Governorate (150 healthy women and 150 patients diagnosed with osteoporosis). Results estimated that the most of healthy women (39.33%) were between 24 < 40 years old. While (38.70%) were between 40 - 55 years old in patients. The highest percentage of educational level for healthy women was 44% (secondary school), whereas, in patients was 43.3% (bachelor). The largest proportion of healthy women and patients had family income from 2000 < 4000 LE per month. 66% of healthy women hadn't relative suffering from osteoporosis. 48% of patients had fractions. Also, the results indicated that there were statistically significant differences in healthy women and patients and their age, education, job, marital status, history of osteoporosis in the family, menstruation, fractures, calcium and vitamin D supplements and physical exercises. Television appear to play the main role for osteoporosis information for respondents. The highest percentage of participants had average level of general knowledge, knowledge of rick factors and knowledge of protective factors about osteoporosis. The majority of healthy women and patients (68 and 71.3%), respectively, had average level about food behavior. There were statically significant differences between participants (healthy women and patients) and levels of knowledge about general knowledge, protective factors and total knowledge for osteoporosis. Most of respondents who had average level of knowledge have high education level. Healthy women (30.3%) and patients (45.5%) who had average level of knowledge have fractures and this association is statically significant. The results showed that most of participants who had average level of food behavior, were from average level of total knowledge about osteoporosis and this association is statically significant. The results illustrated that the highest percentage of patients took less than recommended dietary allowance of macronutrients and micronutrients which are important to prevent osteoporosis. It can be concluded that the most of subjects had average level of knowledge and food behavior about osteoporosis, while, low percentage had high level. Therefore, the recommendions are the use of television programs to raise awareness for all people about the prevention of osteoporosis, more effort from doctors and healthcare providers to inform patients about preventing and treating from osteoporosis and attention the government to this subject in its health policies and make more efforts to inform people especially women about osteoporosis.

This work was carried out at Ghazala Experimental Farm, Fac. Agric., Zagazig Univ., Egypt, during the two successive winter seasons of 2015/2016 and 2016/2017, to estimates the genetic parameters for Balady cabbage, using North Carolina Mating Design II. Ten selected plants were used for this study (five as males and other five as females) from Balady cabbage population. Results of this study showed insignificant mean squares for male × female interaction for all the studied traits, except that for stem diameter, leaf width, wrapper leaves weight per plant and head height, which were highly significant. Estimations of additive variance (σ2A) were higher than dominance variance (σ2D) for stem diameter, leaf width, head height, head diameter and head weight per plant (yield), indicate the important of additive gene action in the inheritance of these traits. Nevertheless, σ2D was higher than σ2A for stem height from wrapper leaves to head, leaf length, and wrapper leaf number and weight per plant, so that the dominance was played very important role in the inheritance of these traits. The heritability in broad-sense ranged from -4.30% for stem height up to wrapper leaves to 83.80% for leaf width. While, narrow-sense of heritability ranged from -2.10% for stem height up to wrapper leaves to 97.35% for head height. [ABSTRACT FROM AUTHOR]

This study was carried out in the Experimental Farm, Fac. Agric., Zagazig Univ., Sharkia Governorate, Egypt, during 2015 and 2016 seasons to find out the effect of irrigation intervals (10 and 16 days) under four bio and mineral fertilization treatments on physiological, anatomical features, growth and yield of yellow maize cultivar single cross 168. The combined analysis detected significant decrease in maize leaf photosynthetic pigments, photochemical activity, histological features, growth and most yield attributes of maize due to prolonging the irrigation interval to 16 days except each of plant height, ear leaf area, ear length and diameter, number of rows per ear and number of grains per ear which were not significantly affected by irrigation interval. The bio and mineral fertilization treatments caused significant effects on all previous traits. Combined application of biofertilizers with 60 or 80% of the recommended levels of NP gave significant increments in values of leaf photosynthetic pigments, photochemical activity, histological features, growth and yield attributes of maize except both plant height and number of rows per ear which were not significantly affected by fertilization treatments. The interactions between the studied factors had significant effects on some growth and yield attributes. These results are quite interesting as they refers to a complementary positive role between biofertization, mineral NP fertilization and soil moisture content and hence help in minimizing the use of mineral NP fertilizers beyond to 40%. Cerealin + Phosphorein + 60% NP under 16-days irrigation interval treatment can be suggested as a recommended treatment to obtain a promising maize grain yield, saving irrigation water and to minimize soil pollution.
