.in order to investigate the effects of plant growth promoting rhizobacteria and nitrogen fertilizer on morphological traits of german chamomile (matricaria chamomilla l.), a field experiment was carried out as factorial based on randomized complete block design with three replications in research farm of the faculty of agriculture, university of tabriz, iran, during 2007-2008. factors were ino...

One of the challenges harnessing higher productivity levels and sustainability agriculture related to N fertilization is in expanding soil N2O emissions, which has become a serious issue recent years. Recent studies suggest that biochar may be solution this problem, but there still knowledge gap application rates its reapplication Central Europe; therefore, study, we investigated effect (initia...

Understanding the combined effects of sowing patterns and nitrogen (N) management strategies on crop productivity, environmental costs, economic benefits is important to ensuring sustainable development dryland agriculture. Thus, we conducted a three-year field experiment explore two spring maize (FS, flat sowing; RFPM, ridge furrow plastic film mulching) four N (N0, no fertilizer; N1, normal u...

In order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the College of Agriculture, Shiraz University, Shiraz, Iran during 2010 and 2011 growing seasons. Two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included...

In wheat production, improving resource utilization and grain yield is the goal researcher have been pursuing. This study aimed to investigate if a regulated nitrogen (N) selenium (Se) fertilizer management could increase N use efficiency (NUE). reports effects of three application levels (N0: 0 kg ha−1, N1: 180 N2: 270 ha−1) combination Se (Se0: g Se1: 450 Se2: 900 on metabolism, NUE in 2020–2...

This study was conducted during 2008-2009 to investigate the influence of different organic nutrient combinations on yields and quality of strawberry cv. Kurdistan in Iran. The experiment comprised of five organic nutrient treatment combinations including the recommended dose of N, P and K through chemical fertilizer as control. Treatment N2 (manure+Azotobacter+ woodash+phosphorus solubilizing ...

Land-use and agricultural practices affect the soil microbial carbon (C) and nitrogen (N) turnover and hence the biosphere-atmosphere exchange of greenhouse gasses (GHG), namely N2O, CH4 and CO2. In view of the global importance of irrigated agriculture, it is crucial to understand how and to which extent this land-use system interferes with the terrestrial N and C cycles and contributes to the...

The aims of this study were: (1) to determine the response growth and yield purple eggplant variety Yufita F1 application Mutiara NPK fertilizers KayaBio biological their interactions (2) obtain appropriate doses fertilizer produce good variety. This research was conducted from March June 2020 at Experimental Garden East Kalimantan Institute for Agricultural Research Technology, Jalan Gunung Li...

Nitrous oxide (N2O) is one of the key greenhouse and ozone (O3) depleting gas, constituting 7% of the anthropogenic greenhouse effect. On a molecular basis, N2O has 310 and 16 times higher global warming potential than that of CO2 and CH4 respectively over a 100-year period. To develop mitigation tools for N2O emissions, it is imperative to understand the processes of nitrogen (N) transformatio...

Plant growth is directly dependent upon an adequate supply of fixed nitrogen. Water and fixed nitrogen are the most common limiting factors for plant growth.There is an abundance of nitrogen in the atmosphere, but it is in the form of the relatively inert gas, N2, and this must be converted chemically or biologically into a more active form before plants can utilize it. Chemical fixation most c...
