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.

This work was carried out during the two autumn seasons of 2015 and 2016 at Ghazala Experimental Farm, Fac. Agric., Zagazig University to study the effect of mineral nitrogen fertilizer levels (15, 25 and 35 kgN/fad.) and lithovit levels (0, 2, 4 and 6 g/l) as well as the interaction between them on growth, seed yield and anatomical traits of cowpea plants grown in clay soil. Fertilizing cowpea plants with mineral N at 35 kg/fad., increased plant height and number of both leaves and branches/plant, total dry weight/plant, as well as seed yield/fad., and N, P, K, total carbohydrates and total protein in seeds. Whereas N at 25 kg/fad., increased dry weight of leaves and branches/plant as well as N,P and K uptake in leaves and branches compated with low used level of 15 kg N/ faddan. Spraying cowpea plants with lithovit at 6g/l induced all previous characters as well as N, P and K uptake in leaves and branches. The interaction between N at 25 kg/fad., and lithovit at 6 g/l increased plant height, number of both leaves and branches/plant, total dry weight/plant, N,P and K uptake by leaves and branches, seed yield/fad., and N, P, K total protein in seeds. As for the effect of N levels and foliar application with lithovit on anatomical structure of vegetative organs of cowpea, it could be stated that 25 kg mineral nitrogen appeared a decrease in the main stem diameter, thickness of cortex, fiber, phloem, xylem and pith diameter, number of vascular bundle and diameter of vessel compared with high level of 35 kg N/fad., whereas the same level of N and lithovit at 6 g/l showed an increase in all previous characters except fiber thickness. Application of 25 kg mineral N/fad., caused in reduction in midvein, lamina of leaflet blades, palisade and spongy tissue thickness and dimensions of midvein bundle compared with high level of 35 kg N/fad., but the same level of N and lithovit reflected an increase in thickness of midvein region, width of midvein bundle, number of vessels/ midvein bundle and average diameter of vessel, but decreased the thickness of leaf lamina.

The present work was carried out in Vegetable Private Farm at Al-Mothalath Village, Abou- Hamad Distrect, Sharkia Governorate during two successive summer seasons of 2014 and 2015, to study the effect of plant spacing (20, 30, 40 and 50 cm) and apical bud pinching (ABP) stages (ABP at the 4th node, the 6th node, 8th node and without ABP) on growth and productivity of okra cv Balady Ahmar under sand loam soil conditions and using surface irrigation system. Obtained results could be summarized as follow: Plant height and total green pods yield/fad., increased with the closest plant spacing (20 cm), whereas number of branches/ plant and leaf area, dry weight of leaves and total dry weight/plant, number of green pods/plant and green pod yield/ plant were increased with the widest plant spacing (50 cm). Number of leaves/ plant was increased with 40 cm plant spacing. The longest plants were recorded with the control treatment (without ABP), whereas ABP at the 4th node increased number of leaves/plant, dry weight of leaves and total dry weight/ plant and ABP at the 8th node increased number of branches/plant. On the other side, apical bud pinching at the 6th node (ABP at 35 days after seed sowing) increased number of green pods yield/plant, green pod yield/plant and total green pod yield/faddan. The interaction between plant spacing at 30 cm and ABP at the 6th node, increased number of leaves/plant, whereas the interaction between plant spacing at 50 cm and ABP at the 6th node increased number of branches / plant, dry weight of leaves and total dry weight/ plant, number of green pods / plant, green pod yield / plant in both seasons. The narrow plant spacing (20 cm) and ABP at the 6th node increased total green pod yield/faddan. [ABSTRACT FROM AUTHOR]
