The article describes a new method to assess the response-ability of 4 chili pepper F1 species: Chanh Nong, Chanh Phong, Mui Ten Do, and EV258 based on the different concentrations of NaCl or CaCl2 (0, 50, 100, 200, and 300 mM). This experiment was conducted in invitro and greenhouse conditions within 12 weeks by investigated the growth and developmental parameters. Our experiment showed that salt stress caused a decrease in all indicators at higher salt concentrations. Typically, at 200 mM salt level, 100% Chanh Phong seeds germinated while less germination was found in Mui Ten Do genotype (89%), following EV258 genotype (72%) and Chanh Nong genotype (61%), respectively. While at 300 mM salt level, this rate significantly decreased the germination rate of Chanh Nong genotype (50%) and increased the period of germination from 6 to 9 days compared to the control treatment. Similarly, growth parameters such as plant height, number of leaves, number of branches, number of flowers, and leaf area also decrease as increasing salinity; however, total phenolic compound and antioxidant activity increased. New research results indicated that the Chanh Phong genotype is potentially considered a salt-tolerant stress plant and can be used for chili pepper cultivation under climate change conditions, especially on saline lands.

This study was carried out in the nursery of Department of Horticulture and Landscape Design, College of Agriculture, University of Basrah during 2018 growing season. Completely randomized blocks design (C.R.B.D.)  was used to investigate the effect of different concentrations of super swing (0, 0.5 and 1) g.l-1 and whey (0, 50 and 75) % and their interactions to enhance the growth parameters and chemical characteristics of Sour orange transplants. The results showed a significant increase in most of the measured growth parameters of transplants treated with high concentration of foliar spraying to both fertilizers. Application of super swing at 1 g.l-1 with whey at 75% together significantly increased the height of plant, the number of leaves, leaf area, the diameter of stem, number of flowers, the leaves content of both nitrogen and potassium, percentage of dry matter, and content of chlorophyll. Whereas, control treatment was significantly increased the water content compared to other treatments. Addition of growth-enhancing compounds such as super swing and whey extract to the plant can improve the metabolic performance and enhances the plant's ability to absorb nutrients from the soil.

Abstract Root rot and wilt disease complex was detected in several fig (Ficus carica L.), grapevine (Vitis vinifera L.), and pomegranate (Punica granatum L.) transplants in nurseries and new orchards of the El-Kharga, Baris, Balate, El-Dakhla, and El-Farafrah districts, of the New Valley governorate, Egypt. The percentage of root rot/wilt incidence and severity on fig, grapevine, and pomegranate transplants in the surveyed districts differed. The average percentages of root rot/wilt incidence and severity, in the surveyed districts, were 41.26, 31.42% in fig, 38.2, 29.5% in grapevine, and 32.1, 23.7% in pomegranate transplants, respectively. The most frequently isolated fungi from rotted roots of fig, grapevine, and pomegranate transplants were Fusarium oxysporum, Rhizoctonia solani, and Macrophomena phaseolina. In pathogenicity tests, all the tested fungi were pathogenic to fig, grapevine, and pomegranate transplants. Under laboratory conditions, all of the following tested bio-agents: Azotobacter sp., Bacillus cereus, B. megaterium, and B. subtilis, were able to inhibit growth of the causal pathogens to different degrees. The effect of these bio-agents individually and/or mixed, when used as a soil drench treatment, were varied in reducing the incidence and severity of root rot/wilt diseases in fig, grapevine, and pomegranate transplants under greenhouse conditions. The mixed bio-agents gave the highest protection against root rot/wilt diseases compared with the individually used of bio-agents. All treatments significantly increased plant height, number of leaves/transplant, leaf area, fresh and dry weight/transplant compared with the control treatment.

Field trials were conducted during 2011 and 2012 cropping seasons at the Teaching and Research Farm of Federal College of Horticulture Dadinkowa in Sudan savanna agro-ecological zone of Nigeria. The objectives of the trial were; to determine the effects of farmyard manure and integrated weed management on okra growth. The treatments were laid out in a split-plot design with farmyard manure rates occupying the main plots; while integrated weed management rates were allocated to the sub-plots and replicated three times. Farmyard manure was applied to affected plots a week before sowing okra, while pendimethalin 500 EC was applied pre-emergence at the rate of 2.5 kg a.i. ha-1 immediately after sowing. Results revealed that the effects of farmyard manure and integrated weed management were significant on plant height (P≤5%), number of leaves plant-1, number of branches plant-1 and leaf area plant-1. It was observed that the control treatments of no farmyard manure applied and no weed control significantly gave lower means on okra growth parameters, while application of 4 t ha-1 of farmyard manure and weeding once at 2 + 4 + 6 + 8 WAS together with 2.5 kg a.i. ha-1 of pendimethalin 500 EC significantly gave higher means on the same traits, as well as integrated weed management.

Smoke Water

The ecologic significance of smoke-related seed germination is now well recognized. Consequently, smoke solutions and a pure butenolide, the active compound from smoke that stimulates germination of a number of plant species, show great potential for enhancing the growth of vegetable crops. Achieving maximum production and better and faster growth of the seedlings has always been a priority for vegetable growers. This study therefore highlights the effects of foliar application of smoke-water and a butenolide on seedling growth of okra [Abelmoschus esculentus (L.) Moench] and tomato (Lycopersicon esculentum Mill.). Treating okra seedlings with smoke-water (1:500 v/v) showed a significant (P < 0.05) increase in shoot/root length, shoot fresh/dry weight, number of leaves, total leaf area, and stem thickness compared with the control treatment. Treatment of okra seedlings with smoke-water significantly (P < 0.05) increased the absolute growth rate (AGR) per week. However, the seedling vigor index (SVI) did not improve as a result of no change in root fresh weight. On the other hand, foliar application of smoke-water and butenolide showed a pronounced effect on the seedling growth of tomato. Most of the growth parameters examined for both the treatments were significantly (P < 0.05) increased, resulting in a significantly (P < 0.05) higher SVI and AGR than the control. This study indicates that the foliar application of smoke-water or butenolide may be a useful and inexpensive technique for enhancing seedling growth of vegetable crops.

The elevated levels of copper and <em>myo</em>-inositol in the MS medium were demonstrated to enhance culture growth and morphogenetic response of apple and pear explants. The results revealed that the highest number of branches per explant (2.80) for apple was obtained from the levels of 0.0+ 100 and 0.050+400 mg/l of both copper and <em>myo</em>-inositol, respectively (C1M2 and C4M4), while for pear 3.40 branches per explant were achieved from the same treatment. The mean length of branches was significantly lower in the case of the control treatment (the absence of copper and inositol). The highest number of leaves per explant (29.73 and 29.80) for both apple and pear, respectively, was recorded for treatment C4M4 (0.050+ 400 mg/l of both copper and <em>myo</em>-inositol, respectively. At the rooting stage, the elevated levels of copper and <em>myo</em>-inositol were very effective in stimulating root formation in both apple and pear shoots. The highest number of roots in apple (2.00 roots/ explant) was achieved while using 0.100+ 800 (C5M5) of both copper and <em>myo</em>-inositol, whereas the highest number of roots for pear (3.17 roots/ explant) was recorded for C6M6 (0.200+ 1600). The highest mean length of roots for apple reached 1.23 cm in treatment C3M3 and 1.10 cm for pear in treatment C6M6. These data suggest that the higher levels of copper and <em>myo</em>-inositol enabled shoot and root formation in the explants, and it might be necessary to use higher levels of these two medium components in order to enhance morphogenetic potential of explants.

The experiment was conducted at the Agricultural Research Field of International University of Business Agriculture and Technology, Dhaka during the period from August to October 2020 to investigate the response of different doses of nitrogen fertilizer on the growth and yield of Kangkong (Ipomoea reptans poir). The experiment consisted of four nitrogen fertilizer levels viz. T0: no fertilizer, T1: 60 kg nitrogen fertilizer, T2: 80 kg nitrogen fertilizer, and T3: 100 kg nitrogen fertilizer per hectare. The result revealed that plant height, number of leaves per plant, number of branches per plant, fresh weight per plant, dry weight per plant, root length per plant, fresh weight of root per plant, dry weight of root per plant, yield per plot and yield per hectare grown under different doses of nitrogen fertilizer viz. control (T0), 60 kg N per hectare (T1), 80 kg N per hectare (T2), showed significant reduction than those grown in 100 kg N per hectare (T3). The experiment was conducted following Randomized Complete Block Design (RCBD) with four replications. The application of different doses of nitrogen significantly influences the growth and yield of Kangkong. The maximum plant height, number of leaves, number of branches, fresh weight per plant, root length was obtained from T3 treatment while the minimum was found from the control treatment (T0) at 60 days after sowing. The highest yield (17.87 t/ha) was performed from the treatment T3 and the lowest yield (11.83t/ha) was obtained from the control treatment where no nitrogen was used.
