Fertilization of soybean with zinc (Zn) had received considerable attention in recent years due to world-wide spread its deficiency soils and also malnutrition infants children’s. Soybean is high nutrient exhausting crop but sensitive soil. Application Zn fertilizers could be a viable option fulfil this promote yield growth parameters. This experiment was conducted at Jawaharlal Nehru Krishi Vi...
Ginkgo biloba L. is one of the most extensively planted and productive commercial species in temperate areas around the world, but slow-growth is the most limiting factor for its utilization. Fertilization is one of the key technologies for high quality and high forest yield. To better understand the impacts of fertilization on Ginkgo productivity, the effects of fertilization treatments (singl...
This study is about an improved high-quality light-emitting diode (LED) converter for a T8 LED tube. The separated into the AC driving circuit and DC circuit. Also, tube was applied with output ripple eliminator optical performance. are assembled at end of in G13 base dummy, respectively, located on PCB. proposed founded SSBB (single-stage buck-boost) topology designed 10 W operation 600 mm lig...
Recent human population increase has been enabled by a massive expansion of global agricultural production. A key component of this "Green Revolution" has been application of inorganic fertilizers to produce and maintain high crop yields. However, the long-term sustainability of these practices is unclear given the eutrophying effects of fertilizer runoff as well as the reliance of fertilizer p...
Fertilizer application is a common anthropogenic alteration to terrestrial systems. Increased nutrient input can impact soil microbial diversity or function directly through altered soil environments, or indirectly through plant-microbe feedbacks, with potentially important effects on ecologically-important plant-associated mutualists. We investigated the impacts of plant fertilizer, containing...
This study was conducted to determine the efficacy of using enhanced efficiency fertilizer (EEFs) products compared to urea to improve fertilizer nitrogen use efficiency (FNUE) in forest plantations. All fertilizer treatments were labeled with 15N (0.5 atom percent) and applied to 100 m2 circular plots at 12 loblolly pine stands (Pinus taeda L.) across the southeastern United States. Total fert...
AIMS The recent increases in food prices caused by the corresponding increases in fertilizer costs have highlighted the demand for reducing the overuse of fertilizers in industrial agriculture. There has been increasing interest in developing plant root-targeted delivery (RTD) of fertilizers in order to address the problem of inefficient fertilizer use. The aim of this study is to develop a low...
1 Why don’t farmers use fertilizers: 2 Evidence from Field Experiments in Western Kenya 3 (PRELIMINARY AND INCOMPLETE) 4 April 29, 2006 5 6 Esther Duflo, Michael Kremer and Jonathan Robinson 7 8 9 Abstract 10 11 This paper reports on randomized field experiments set up to investigate 12 various reasons for the low usage of fertilizer in Western Kenya. 13 Demonstration plots set up on farmer’s f...
The study on linseed aimed to investigate the effectiveness of fertilizer and organic spray banana pseudostem sap or vermiwash yield, quality, uptake economics crop was conducted at College Farm, N. M. Agriculture, Navsari Agricultural University, during rabi season 2019-20. experiment laid out in Randomized Block Design with four replicates. experimental field fairly leveled uniform. treatment...
15N-labeled fertilizer was applied to Sorghum at different rates (0, 100 kg N.ha -1 ) to 1m2 microplots and with two kind of water (well water “WW” and treated wastewater “TWW”) to Sorghum grown in field during 1997 and 1999. Increases in DM production, N uptake and 15 NRF were observed with TWW. About 17% and 36% of the 15Nfertilizer were recovered in the crop with TWW in 1997 and 1999, respec...
