“…A adequada oferta de nutrientes reflete em maior desenvolvimento dos órgãos vegetativos e reprodutivos, uma vez que essas substâncias fazem parte do complexo sistema fisiológico das plantas e seus processos, tais como a fotossíntese, produção de proteínas, ativação de enzimas, divisão e expansão celular, entre outros (Taiz et al, 2017). Para plantas de Zinnia elegans, observa-se resposta positiva no desenvolvimento vegetativo e na qualidade das flores com a utilização de fertilizantes minerais e orgânicos (Chattopadhyay, 2014;Elhindi et al, 2016;Mladenović et al, 2015;Sultana et al, 2015), aumentando seu valor de comercialização.…”

O estudo objetivou avaliar a produção de mini plantas de Zinnia elegans em substratos com diferentes concentrações de composto a base de resíduo de agroindústria. Para a condução do experimento, utilizou-se delineamento inteiramente casualizado, com nove repetições. Os tratamentos foram compostos por cinco diferentes concentrações de substrato Ecosolo® (0, 25, 50, 75 e 100%), em que se realizou o cultivo de Zinnia elegans. Foram avaliadas as características de altura de planta, diâmetro do colo, número de folhas, diâmetro de flor e número de pétalas. Com exceção do número de folhas, todas as variáveis foram incrementadas linearmente, conforme foi elevada a participação do Ecosolo® na formação do substrato. Desta maneira, concluiu-se que o Ecosolo® substitui parcialmente ou totalmente o substrato turfoso na produção de mini plantas de Z. elegans, incrementando as características biométricas conforme se elevam as concentrações do produto.

“…Drip irrigated and/or fertigated tomatoes increased water use efficiency by 25 and 17% relative to nonirrigated tomatoes for the light and the heavy soils, respectively, drip and fertigation increased P and N use efficiency for both soil types (Phogat et al 2013). Subsurface drip irrigation system was found to be more efficient than surface drip irrigation system to obtain maximum yield accompanied by the highest nutrients concentration in zinnia plants and soil fertility after harvest (Elhindi et al 2015). Shingade et al (2012) found that fertilization treatments saved 60.68 % of irrigation water and 20 to 40 % nutrients over surface irrigation system.…”

Onion is the most widely-used flavoring vegetable in the world. And it is an important export crop in Egypt about 17%  529.631Tg., from total annually production. Scarcity of water resources in Egypt (arid and sigemi-arid regions) threatening food security. As well as, it is a limiting factor in agriculture expansion. So, maximizing irrigation water productivity by right combination of water and nutrients, and the method of fertilizer application through field water management practices (modern irrigation techniques, and fertigation) in irrigated crops, are a pre requisite for higher yields and good quality production. On the other hand it is very important to overcome water shortage and encourage environment preservation, particularly in sandy soils. Field experiment was conducted during 2016 /2017 season in private farm at Alexandria Cairo desert road, El-Behiara governorate. To study the effect of fertigation technique on some physical onion yield (quantity) i.e., bulb diameter "d1 and d2" (cm)., bulb mass "Bm" (g), bulb actual volume "Bv" (cm 3), moisture content "MC" (%), and bulb yield "BY" (Mg fed-1)., through three emitters type, i.e., on line OT4 (I1), built in drip line GR 16 (I2) and built in drip line antiroots (I3), to obtain maximum irrigation water productivity, highest fertilizer effective, promoting yield quantity and quality and preservating environment of hyper mismanagement of water and fertilizer. Generally, results showed that using (I3) treatment recorded higher values compared with (I1) and (I2) treatments. Where, results indicated that, bulb yield "BY" (Mg fed-1) values increased about 8.32 and 2.77%., by using (I3), compared with (I1), and (I2). Also, using (I3) lead to increased irrigation water productivity "IWP" (kg m-3) about 66.1 and 33.2%., compared with using (I1), and (I2). In addition, it could be seen that bulb mass "Bm" (g), was increased by 60.77 and 14.39 %, when using (I3) compared with (I1) and (I2).

“…Also, Xu and Leskovar (2014) on cabbage showed that 75% ETc irrigation had little influence on photosynthetic rate but it temporarily increased chlorophyll and carotenoids content and reduced stomata conductance. Elhindi et al (2016) demonstrated that salt stress impacted adversely the relative content of leaf water and the plant chlorophyll content, while it increased the electrolyte leakage of coriander plant.…”

A strip-plot experiment was carried out during the two winter seasons of 2018/2019 and 2019/2020 at a private farm located in Demiana village, Belqas District, Dakahlia Governorate, Egypt. This study aimed to investigate the impact irrigation water levels and some potassium forms on garlic (cv. Balady) vegetative growth, water relations and leaves pigments, bulbs physical and chemical quality as well as yield and its components. Irrigation water level treatments were 50%, 75% and 100% full irrigation and different potassium forms (without, potassium citrate, potassium nitrate and potassium thiosulfate) at concentration of 1000 ppm as foliar spray. Results showed that all studied traits of garlic were significantly decreased with water irrigation deficit except electorate leakage, leaves and cloves dry matter, net ratio percentage, water use efficiency for fresh and cured yield and loss weight percent were improved. The highest values of all characters were achieved by potassium thiosulfate. However, the best values for leaves and cloves dry matter and loss weight percentage exhibited by potassium citrate. In addition, the most promising results were obtained from garlic plants treated with potassium thiosulfate interacted with full irrigation treatment which followed by the interaction treatment of full irrigation level with potassium citrate. It can be recommend treating garlic plants with potassium thiosulfate (1000 ppm) to improve yield and water use efficiency. As well as, potassium citrate (1000 ppm) to increase cloves dry matter and eliminate weight loss of cured yield of garlic bulbs under different irrigation levels.
