The main factor affecting fruit quality and post-harvest loss in kiwifruits is improper tree nutrition. In this study, fruits were harvested from 24 different orchards in the east of Guilan province when the total soluble solid content of the fruit was 6.2°. percent the fruts was. Fruits’ mineral content such as nitrogen, phosphorus, potassium, calcium and magnesium, the mineral elements ratios...
To investigate the effect of plant residues in increment of soil organic matter and nitrogen, a randomized complete block design (RBCD) with 4 replications using 10 different plant species was carried out in 2009. The studied plants belonged to three families including Gramineae (Sorghum bicolor, Panicum miliaceum and Avena sativa), Brasicaceae (Eruca sativa) and Leguminoseae (Trifolium pratens...
Abiotic nitrogen reduction (ANR) in hydrothermal systems has been long considered as the most likely mechanism to transform N2, the dominant N species on the pre-life Earth’s surface, into NH4+, an essential compound for abiotic synthesis of large organic molecules facilitating the emergence of life in the early oceans [1]. Mineral-induced ANR process has been demonstrated by laboratory experim...
Effects of bio-nitrogen fertilizer (bio-N), as a partial alternative to mineral-nitrogen fertilizer (mineral-N), on growth, yield and yield quality of broccoli plants were investigated. Bio-N was applied at 1, 2 or 3 doses in combination with 65% of the recommended dose of mineral-N (bio-N1, bio-N2 or bio-N3 + 2⁄3mineral-N). However, 100% of the recommended dose of mineralN was applied as a con...
Introduction Conclusions References
Nitrogen use efficiency and life cycle of root nodules in alfalfa after different mineral fertilization and soil cultivation practices were studied. Field trial was conducted in the Institute of Forage Crops, Pleven, Bulgaria on leached chernozem subsoil type and no irrigation. The next treatments were tested: i) for fertilization as follows: N0P0K0 (control); N60P100K80 (an accepted technology...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
Effects of different coagulant enzymes used on quality of traditional Örgü cheese (Braided cheese)
In this study, Örgü cheese has been produced by using different coagulating enzymes (calf rennet, microbial enzymes, recombinant chymosin). The effects of different coagulating enzymes which are used on the characteristic of mineral material and cheese has been observed during 90 days ripening time. Mineral material contents of Örgü cheese have been determined with ICP-OES (inductively coupled ...
From preliminary studies of the feeding value for mediumwool Merino wethers of various samples of sorghum silage, the following points emerge : 1. Mature silage, in addition to being moderately unpalatable, had a low level of digestible protein, a variable digestible crude fibre and a high mineral content. In spite of the latter, most sheep had negative mineral balances. A feature of the ash co...
Symbioses are modelled as evolutionarily and ecologically variable with fitness outcomes for hosts shifting on a continuum from mutualism to parasitism. In a classic example, rhizobia fix atmospheric nitrogen for legume hosts in exchange for photosynthetic carbon. Rhizobial infection often enhances legume growth, but hosts also incur interaction costs because of root tissues and or metabolites ...
