in order to investigate lentil response to application times and amounts of zinc, an experiment was arranged as factorial based on randomized complete block design with four replications on farm research of gonbad higher education center during 2008-2009. treatments were application times (before flowering and beginning of pod setting) and application rates (0, 0.5, 1, 1.5 and 2 liter per hecta...
This experiment was conducted to determine the effects of time and rate of nitrogen fertilizer (urea) application on yield and yield components and quality of sunflower (Helianthus annuus L. )cv.Euroflor. A field experiment was carried out at College of Agriculture, Shiraz University during Summer 2009. The experimental design was a factorial based on a randomized complete block design with 3 ...
Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...
background: bio-stimulators as biological substances stimulate metabolism and metabolic processes, which can be increase plants yield and secondary metabolites content. objective: the aim is to introduce bio-stimulators as bioactive amino acid compounds to increase yield and help to sustainable agriculture. methods: this experiment was conducted at acecr on the base of randomized complete block...
In order to recognize the soybean tolerant genotypes, a greenhouse as factorial experiment was conducted in form of randomized complete block design with three repetition in 2017 in Damavand. The first factor contained 15 soybean genotypes and second factor included two levels of normal irrigation and irrigation disruption in time of podding. The traits included plant height, reproductive ...
In order to evaluate cold tolerance of twenty barley genotypes under field conditions, an experiment was carried out in a randomized complete block design at 3 sowing dates of October 5, November 5, and December 5 in Saatlu Agricultural Research Station, West Azarbaijan, Iran, during 2010-11 seasons. Also, another experiment was conducted on the same genotypes based on a completely randomized d...
Tillage methods are among the most successful factors in agriculture that have a significant impact on the quality and quantity of agronomic plants. To evaluate different tillage methods and urea fertilizer with nitrapyrin on total chlorophyll content, grain protein, yield, and yield components of two barley (Hordeum vulgare L.) cultivars, an experiment was conducted as split factorial in the r...
in order to study the influence of municipal waste compost and chemical fertilizer on yield and yield components in maize (zea mays l.) an experiment was conducted at research farm of sari agricultural sciences and natural resources university during 2007. the experiment was arranged in split plots based on complete randomized block design with two factors and three replications. main plot incl...
In this study, the effects of nitrogen fertilizer and plant growth regulator (ethephon) application on leaf chlorophyl, stem height and diameter, stalk yield, total sugar and bioethanol of sweet sorghum were determined. Four nitrogen treatments 0, 100, 200 and 300 Kg Urea ha-1 and four ethephon concentrations 0, 800, 1000, and 1200 ppm were applied on sweet sorghum in a split plot on randomized...
in order to evaluate the effects of nitrogen fertilizer on yield, yield components and dry matter remobilization of different rice genotypes, a field experiment was carried out at the farm of ramin agricultural and natural resources university (ahwaz/iran) during 2007. experiment was arranged in a split plot based on randomized complete block design with three replications. four nitrogen fertil...
