in this research for study the effects of nitrogen fertilizer on yield and yield components of current rice cultivars was an experiment as factorial in rcbd with three replications where conducted during 2009 year in two locations (rice research institute, rasht, and rudsar, east of guilan). factors were cultivars (khazar, ali kazemi and hashemi), and nitrogen fertilizer levels (0, 30, 60, and ...
In order to assess the effects of different pesticides on nutrient levels of rice, three pesticides (Diazinon, Tricyclazole and Butachlor) which are commonly used in paddy fields in Iran were selected in a randomized complete block with 3 replicates in field condition. The result indicated that the impact of different pesticides on total protein and nitrogen, phosphorus and potassium ...
Including food production in non-food systems, such as rubber plantations and biofuel or bioenergy crops, may contribute to household food security. We evaluated the potential for planting rice, mungbean, rice cultivar mixtures, and rice intercropped with mungbean in young rubber plantations in experiments in the Arakan Valley of Mindanao in the Philippines. Rice mixtures consisted of two- or t...
Silicon is as an essential element for crops and an important food source for the growth of rice plant. If no adequate replacement for this element, plants are faced with a shortage of silicon causing serious eating disorder and instability in plant resistance to pests. This research was done to investigate the effect of silicon on growth, yield and tolerance to rice stem borer in Tarom Hashemi...
In order to physiological and biochemical evaluation of seventh generation of rice mutant tolerant lines under salinity stress, an experiment was carried out as split plot arranged in a Completely Randomized Design with four replications. Main factor of experiment includes three levels of salt stress (0, 45, 75 mmol/l) and sub factor include 5 local rice mutant lines contain Tarom Hashemi 1, Ta...
Since more than 75% of the rice fields in Iran are located in the Northern provinces i.e. Mazandaran, Guilan, and Golestan identifying the crop water requirement of rice fields is essential for water resources planning in the Northern provinces. The objective of this research was to ascertain the crop water requirement of two rice cultivars namely Hashemi and Khazar in Guilan province during...
As one of the most important crops, rice provides the major food for more than half of the world population. However, its production is limited by many environmental factors, among which high temperature stress (HS) frequently occurs during anthesis and reduces its spikelet fertility. To explore the mechanism of HS tolerance in rice, we conducted a comparative proteomics analysis on the anthers...
The objective of this study was to determine the effects of water regime/soil condition (continuous flooding, saturated, and aerobic), cultivar ('Cocodrie' and 'Rondo'), and soil texture (clay and sandy loam) on rice grain yield, yield components and water productivity using a greenhouse trial. Rice grain yield was significantly affected by soil texture and the interaction between water regime ...
The present study sought to compare the effect of seed priming by hydropriming, ascorbate and calcium chloride (CaCl2) versus different concentrations of silver nanoparticles on two Iranian rice cultivars (Hashemi and Shiroodi) under drought stress. The experimental design, which was factorial, was completely randomized. The first factor was control (without priming), hydro-priming, 20 mg.L-1 c...
Mutagenesis has been one of the important sources of genetic diversity and Plant mutants can be important bio-resources for crop breeding and functional genomics studies. Breeding conventional methods for generating of genetic variability are of low efficiency. We showed that treatment of seeds of rice(Hashemi cultivar) with 0.8% EMS for 8 h caused visible phenotypic variations on M2 rice mutan...
