Controlling Growth of Sanchezia Plant by Foliar Application of Micronutrients and Paclobutrazol
Amaal
Heikal
A POT EXPERIMENT was carried out to evaluate the effect of foliar application of micronutrients mixtures and paclobutrazol on controlling growth of sanchezia plants. The experimental treatments were laid out in a split plot arrangement using a randomized complete block design. Micronutrients mixtures of Zn + Mn + Fe+ B at 50 (C1), 100 (C2) and 150 (C3) ppm of each element were assigned to main plot, while paclobutrazoltreatments; 8, 16, and 24 mgL-1 were allocate to sup-plot. Spraying plants with tap water represent control treatments. Foliar application of micronutrients at the level of C2 significantlyenhanced plant growth in terms of plant height, stem diameter, root length, leaf area, number of leaves and inflorescences, fresh and dry matter of leaves, shoots, inflorescences and roots. Total chlorophyll, total carbohydrates, Fe, Zn, Mn and B contents of leaves increased in plants sprayed with micronutrients. The most visible effect of paclobutrazol is the decrease in all studied growth traits. Severe retardation of plant growth was evident at 24 mg a.i.L-1 of paclobutrazol. Foliar application of paclobutrazol enhanced total chlorophyll content up to 16 mg L-1. Plant height, stem diameter and root length linearly decrease with the paclobutrazol concentrations. Application of paclobutrazol at the level of 16 mg L-1 markedly increased total carbohydrates and mineral contents of leaves. The significance interaction between micronutrients and paclobutrazol, especially for plant height and leaf area increase the diversity of potted plants grown for the ornamental plants market.

THE RESPONSE of “Murcott” mandarintrees grown on salt affected soil to different amendments that alleviate salinity stress was studied. The present study was carried out in a privateorchard locatedat“El-Adlia Association”, El-Sharqia Governorate, Egypt, duringtwo successive seasons (20142015/ and 20162017/). Nine different treatments were used as follow: Potassium silicate (PSat500 and 1000ppm), Magnetite (Mag) at a rate of 58 kg/ fed/year, Mag+ PSat 500, Mag+PSat 1000, Unisaleat a rate of 7.9 L/fed., Unisale+PSat500, andUnisale+PS at1000ppmbeside control (Uniform fertilizer program). These different treatments mitigated salinity stress and increased root distribution, photosynthetic pigments, leaves minerals contents, fruit yield and quality of Murcott trees compared with control. The highest yield was obtained by Unisale followed in descending order by PS at 500 ppm and Magnetite treatment. Prolineaccumulation in fresh leaves, soil pH and EC at the end of the two seasons also wererecorded.

SUSTAINABLE agricultural development need to provide alternatives of mineral fertilizers to produce safe food for humans, maintain of soil fertility and preserve of environment from pollution. Field experiment was conducted at the site of Vegetable Research Departments, Horticulture Research Institutein Giza Governorate, Egypt, to study possibility of using compost and vermicompost (compost of earthworm) as substitutes partial or fully for mineral fertilizers used in the production of green beans. The beanseeds (cv. Paulista) were sown in clay soil duringthe summer season of 2016 and 2017. Treatments of compost and vermicompost individually orin combination with or without adding 50% of recommended dose of mineral fertilizers,were investigated on bean plants. The effects of these treatments on the growth and yield of green beans were compared tofull recommendeddose of mineral fertilizers as control. All treatments of compost and vermicompostwithout mineral fertilizers decreased all the vegetative properties of bean plants. Compost and vermicompost singly or in combination + 50% mineral fertilizers were not showed any significant differences compared to 100% mineral fertilizers. The treatments of 100% mineral fertilizers and 50% mineral fertilizers + vermicompost sole or combined with compost gave the highest early and total yield compared to other treatments.Applyingcompost and vermicompostwith or without mineral fertilizers, decreased nitrate content of bean pods. This study suggested possibilityfor using compost and vermicompost to reduce the amount of mineral fertilizers to produce good yield,healthyand safe of green beans.

THE main objective of this study was to produce safe and clean garlic crop.This study was carried out during 2014/2015 and 2015/2016 seasons at El-Kassasein region, Ismailia, Egypt, to investigate the effect of mineral NP fertilizers, biofertilizers and biochar on two garlic cultivars production grown in sandy soil conditions.Sids 40 cultivar recorded the highest neck and bulbdiameters, dry weight of plant parts, marketable and total yields/feddan, N and total protein contents in the bulbs. Fertilization of garlic with 75% NP + 3kg Nitrobein (Nr) + 2kg Phosphorein (Pr) + 3m3 biochar/fed.increased all plant growth characters and yields of grades 1 and 2, marketable, exportable and total/fed., while, with 50% NP + 3m3 biochar/fed.gave the lowest bulb nitrate content. Fertilizing the two cultivars with 75% NP + 3kg Nr + 2kg Pr + 3m3 biochar/fed.increased dry weights of plant parts, as well as yields and its components. Fertilizing Balady plants with 100 or 75% NP + 3kg Nr+ 2kg Pr + 3m3 biochar/fed. gave the highest net returns, followed by Sids 40 with 100% NP + 3kg Nr + 2kg Pr/fed., or with 100% NP + 3kg Nr + 2kg Pr + 3m3 biochar/fed. It could be concluded that fertilization of garlic plants with 100 or 75% NP + 3kg Nr + 2kg Pr+ 3m3 biochar/fed. can improve plant growth, yields and its components with a good bulb quality. Treated garlic plants with biochar positively enhanced plant growth, productivity, and bulb quality. Using previous treatments could reduce the costs, increase net return of garlic production and keep the environment out of pollution.

THIS INVESTIGATION was conducted during the successive seasons (2014& 2015) in a private vineyard located at Menshiat Abdel Nabi village, Aga, Dakahlia Governorate, Egypt. The chosen vines were seven years old, planted in a clay soil, spaced at2×2.5 meters apart and irrigated by flood system. Flame seedless was spur pruned by leaving 7 spurs with two eyes on each cardon, the total load was 56 buds under pergolla trellis system, while Thompson seedless was cane pruned by leaving 6 cans with 12 buds/cane with 6 renewal spurs with two buds for each, the total bud load was 84 buds under double T trellis system. All intercropped peas and clover received cultural managements as recommended by the Egyptian Ministry of Agriculture. The obtained results reveal that intercropping of Thompson seedless and Flame seedless grapevines the used intercropped crops increased N, K and organic matter (O. M) in the soil, which enhanced vines nutritional status, increased total microbial count, vegetative growth, yield and berry quality. Intercropping with peas plants which increased shoot length, leaf area and N and K in the leaves as well as yield per vine, TSS content and total sugars, while reduced the total acidity in berries and increased total microbial count, dehydrogenase and phosphatase enzymes activity in the rhizosphere. In addition, the economic study indicated that intercropping Thompson seedless and Flame with peas gave higher net profit/ Fadden followed by intercropping Thompson seedless and flame seedless with clover crop.

THE PRESENT study was carried out during the two summer seasons of 2016 and 2017 to study the effect of biochar application rates (0, 1.25, 2.5 and 5 m3/feddan (fed.) = 4200 m2) on productivity and tubers quality of three potato cultivars i.e., Accent, Cara and Spunta grown under sandy soil conditions. Cara and Spunta cultivars recorded the highest values of morphological traits, leaf content of Ca, Mn and Cu, as well as tuber yield and quality. Cara cultivar recorded the maximum dry weight of different plant parts, while Spunta cv. recorded the highest values of photosynthetic pigments concentrations in the leaf tissues and the highest tuber starch content. Accent cv. recoded the lowest values of the last mentioned parameters and the lowest tuber nitrate content. Plant growth, leaf photosynthetic pigments and minerals content (N, P, K, Ca, Fe, Zn, Mn, and Cu), yield and its components, as well as tuber quality were significantly increased with increasing biochar application rates up to 5 m3/fed. Treated the three tested potato cultivars plants with different application rates of biochar increased plant growth, leaf photosynthetic pigments, minerals content and tuber yield and its components, compared to those untreated with biochar. Adding biochar at rates of 2.5 or 5 m3/fed. to the three tested potato cultivars Considerably gave the lowest values of leaf nitrate content. Treating Cara cultivars with biochar at rate of 5 m3/fed. gave the highest values of gross and net return, as well as benefits ratio, followed by adding 5 m3/fed. to Spunta plants. Finally, adding biochar to potato plants grown in sandy soil conditions obviously improves potato plant growth, plant chemical compositions, tuber yield and its components, with good tubers quality and increasing net return of potato production and keeps the environment less polluted.

THIS STUDY was carried out during two successive 2016 and 2017 experimental seasons on Flame seedless grapevine grown in private vineyard located in Sohag Governorate, Egypt. It’s were carefully selected as being healthy vines, uniform as possible in their vigour and size to study the effect of foliar spray with rocket oil. Flame seedless is one of the most popular different cultivars of table grapes in Egypt, is dependent upon its desirable appearance. Improving the growth and productivity of this crop by many ways i.e. fertilization, plant hormone, and plant extracts spray application. Flame seedless grapevine treated one, two or three sprays of rocket oil at 0.0125, 0.025, 0.05 and 0.1 %( at the beginning of growth, before bloom and after bloom). Growths, nutritional status, yield and berries qualities in response to rocket oil treatments were investigated. Using rocket oil once, twice or three times at 0.0125 to 0.1% effectively enhanced main shoot length, leaf surface area, leaf mineral content(N, P& K), yield as well as physical and chemical characteristics of berries comparing with the control treatment. Improving on these parameters were increased when increasing rocket oil concentrations and number of times spray. Performing three sprays with rocket oil at 0.1 % gave the highest values with regard to yield and fruit quality of Flame seedless grapevines.

WATER SHORTAGE problem in Egypt is continuously increasing and it is prospected to reach the threshold level of less than 500 m3/year/capita which so-called water scarcity limit. Therefore, the present study was carried out to use alternative irrigation technique I1 (traditional irrigation like to practice by local farmers in the studied area), I2 (irrigation furrow and left furrow with a fixed shape during the growing season) and I3 (irrigation furrow and left furrow with an alternative shape during the growing season) on Lawsonia alba Lam plants and were applied foliar sprayed by potassium, micronutrients and humic liquid fertilizer. Despite, all growth was enhanced under I1, chemical characteristics of henna plants were significantly increased by using I3. The lowest values of applied irrigation water (AW) and water consumptive use (CU) were recorded under irrigation treatment I3 (3397.09 and 3410.32 m3/ fed) and (2001.95 and 2020.49 m3/fed) in the two seasons, respectively. Spraying plants with micronutrients only and micronutrients combined with potassium and humic observed highly growth characters, chemical criteria and the main component in most cases which increasing the leaves yield /fed for about 35.16%, lawsone yield/plant 43.37% and tannins yield/plant 35.64%, respectively when compared to non-sprayed plants. The deficit irrigated (I3) spraying with micronutrients, potassium, and humic liquid fertilizer produced higher water productivity (WP) and productivity of irrigation water (PIW) in comparison to other irrigation treatments for both yields of leaves and lawsone. The decrease of AW in the treatment I3 saving about 25.47% of water in the growing season.
