Investigation of different levels micro nutrients on tomato in ...

Use of greenhouse cultures accompanied by new techniques such as soilless or hydroponic culture on the one hand improves suitable control of plants nutrition and on the other hand it has created a great progress in greenhouse productions. In order to greenhouse tomato cultivar of Hamra was cultured in a hydroponic system and effect of micronutrients different levels was studied on it. The experiment design was as randomized complete block with five treatments and four replications. Experimental treatments were included: Lack of micronutrients application, Full application of sulfate manganese (4.06 mg/lit), Full application of sulfate zinc (4.42 mg/lit), 50% sulfate manganese (2.03 mg/lit) + 50% sulfate zinc (2.21 mg/lit) and Full application of sulfate manganese + Full application of sulfate zinc. The results showed that the highest fresh fruit yield, fruit dry matter percentage and content of Mn and Zn in fruit obtained from full application Mn, Zn and Mn + Zn. However micronutrients different levels had significantly effect on content of nitrogen, but they haven’t significantly effect on fruit size of tomato. Key words: Micronutrients, Tomato, Hydroponic culture, Yield.

Manganese deficiency, Tomato Iron deficiency ... - Pure Hydroponics

pH Management of Hydroponics Solutions A question often asked is what is the best pH for a particular crop nutrient solution. The answers given in many texts, and often by advisers to growers, are frequently based on misunderstood information. Many refer to the availability of nutrients to plants at different pHʼs based on research by Troug (1946) [Proc. Soil Sci. Soc. Am., 11:305-308] even using graphic illustrations of his findings in one form or another, generally showing a bar graph with wide portions in the pH area where the element is most widely available to the plant. I have seen similar representations said to show the availability of trace elements in a hydroponics solution. This graphic representation of availability of trace, and sometimes the major elements, only applies to plants being grown in mineral (clay based) soils. It is not relevant to hydroponics solutions.As plants use nutrients their roots release bicarbonate that raises the pH of nutrient solutions. By the early 1990ʼs I had observed that the published and advised pH at which crops were grown did not correspond to my observations. At the time phosphoric acid was being used to routinely acidify hydroponics solutions and was causing imbalances in nutrient solutions and blockages due to precipitates. It made sense to replace the phosphoric acid entirely with nitric acid which could, by monitoring pH, be added at a rate related to plant use replacing Nitrogen (N) used in growth periods and so maintain a better balanced solution free of unwanted precipitates.

Nitrogen is the most predominantly consumed nutrient among all the macro and micro elements required for plant growth. Nitrogenous fertilizers can be provided by soil application, fertigation or foliar application. In foliar process, concentration of nitrogen varies from 100ppm to 250ppm according to the needs of the plant.

Selanjutnya textbook dijelaskan sebagai “a book giving instruction in a subject used especially in schools” (Crowther, 1995: 1234) yang dapat diterjemahkan bahwa buku teks adalah buku yang memberikan petunjuk dalam sebuah pelajaran khususnya di sekolah. Buku teks adalah buku pelajaran dalam bidang studi tertentu, yang merupakan buku standar, yang disusun oleh para pakar dalam bidang itu untuk maksud-maksud dan tujuan instruksional, yang diperlengkapi dengan saranasarana pengajaran yang serasi dan mudah dipahami oleh para pemakainya di sekolah-sekolah dan perguruan tinggi sehingga dapat menunjang sesuatu program pengajaran (Tarigan dan Tarigan, 1986: 13). Berdasar pendapat tersebut, buku teks digunakan untuk mata pelajaran tertentu. Penggunaan buku teks tersebut didasarkan pada tujuan pembelajaran yang mengacu pada kurikulum. Selain menggunakan buku teks, pengajar dapat menggunakan sarana-sarana ataupun teknik yang sesuai dengan tujuan yang sudah dibuat sebelumnya. Penggunaan yang memadukan buku teks, teknik serta sarana lain ditujukan untuk mempermudah pemakai buku teks terutama peserta didik dalam memahami materi.

How To Prevent Head Gasket Failures Caused By ... - Federal-Mogul

Detonation (also called "spark knock") is an erratic form of combustion that can cause head gasket failure as well as other engine damage. Detonation occurs when excessive heat and pressure in the combustion chamber cause the air/fuel mixture to auto-ignite. This produces multiple flame fronts within the combustion chamber instead of a single flame kernel. When these multiple flames collide, they do so with explosive force that produces a sudden rise in cylinder pressure accompanied by a sharp metallic pinging or knocking noise. The hammer-like shock waves created by detonation subject the head gasket, piston, rings, spark plug and rod bearings to severe overloading. Mild or occasional detonation can occur in almost any engine and usually causes no harm. But prolonged or heavy detonation can be very damaging. So if you hear knocking or pinging when accelerating or lugging your engine, you probably have a detonation problem. 1. Try a higher octane fuel. The octane rating of a given grade of gasoline is a measure of its detonation resistance. The higher the octane number, the better able the fuel is to resist detonation. Most engines in good condition will run fine on regular grade 87 octane fuel. But engines with high compression ratios (over 9:1), turbochargers, superchargers, or with accumulated carbon deposits in the combustion chamber may require 89 or higher octane fuel. How a vehicle is used can also affect its octane requirements. If a vehicle is used for towing or some other application where the engine is forced to work hard under load, a higher octane fuel may be necessary to prevent detonation. If switching to a higher octane fuel fails to eliminate a persistent detonation problem, it probably means something else is amiss. Anything that increases normal combustion temperatures or pressures, leans out the air/fuel mixture, or causes the engine to run hotter than normal can cause detonation. 2. Check for loss of EGR. The Exhaust Gas Recirculation (EGR) system is one of the engine's primary emission controls. Its purpose is to reduce oxides of nitrogen (NOX) pollution in the exhaust. It does this by "leaking" (recirculating) small amounts of exhaust into the intake manifold through the EGR valve. Though the gases are hot, they actually have a cooling effect on combustion temperatures by diluting the air/fuel mixture slightly. Lowering the combustion temperature reduces the formation of NOX as well as the octane requirements of the engine.
