UV-B radiation and EOD light (EOD) quality has both signaling and damaging effects based on the dosage and time of exposure. At highland areas UV-B decreases crop productivity and also light quality increase at high elevation area but EOD light quality effect was not researched based on altitude. Therefore, in the present study a field experiment was conducted to investigate the effects of UV-B...

Fusarium oxysporum JCM11502 expresses a denitrifying (nitrate (NO(3)(-))-respiring) mechanism and can thrive under oxygen (O(2)) limitation. The fungus reduces NO(3)(-) to nitrite at the initial step of denitrification. In this study, we cloned the gene coding NADH-NO(3)(-) reductase (NADH-Nar) (niaD) from F. oxysporum JCM11502. The niaD gene complemented the defective NO(3)(-) assimilation by ...

Cotton (Gossypium hirsutum L. var. ;Stoneville 213'), velvetleaf (Abutilon theophrasti Medic.), redroot pigweed (Amaranthus retroflexus L.), and hemp sesbania (Sesbania exaltata [Raf.] Cory) were grown in a controlled environment room at 31/25 C day/night temperature and three irradiances: 90, 320, and 750 mueinsteins meter(-2) second(-1). From total dry weights and leaf areas determined at int...

the aim of this study was to evaluate the effect of different potassium (k) and nitrogen (n) concentrations in nutrient solution and their interaction on growth and quality of tomato transplants. a full factorial experimental design was carried out with three potassium concentrations (1.5, 3 and 6 meql-1) and three nitrogen concentrations (1.5, 3 and 6 meql-1) for 27 days after seed germination...

The subject of this review is the impact of long-term changes in temperature on plant growth and its underlying components. The discussion highlights the extent to which thermal acclimation of metabolism is intrinsically linked to the plasticity of a range of biochemical and morphological traits. The fact that there is often a trade-off between temperature-mediated changes in net assimilation r...

to determine the effects of priming and planting density on improvement of morphological and physiological traits of the two hybrid corns sc (s.c. 704) under double cropping in sari, a split plot experiment as randomized complete block design with four replications was conducted in 2010. treatments included two densities of 80 and 100 thousand plants per hectare as the first factor and osmoprim...

In order to investigate the effect of sugarcane compost on consumption of nitrogenous fertilizers in corn fields, a research project was conducted according split plot experiment based on randomized complete block design with three replications along 2015 year. The main plot included different chemical nitrogenous fertilizer (Zero; control, 60 and 120 kg.ha-1 pure nitrogen from urea ...

During the rabi season of 2021, a field experiment was conducted in North Western plains Uttarakhand at Crop Research Centre, School Agriculture, Uttaranchal University, Dehradun to examine impact integrated nutrient management (INM) on lentil growth, yield, and economics (Lens culinaris Medik.). The laid Randomized Block Design with seven treatments i.e. T1 (Control, 100% RDF (Recommended Dose...

Background: Water is one of the factors limiting rice cultivation on raindrop land. The provision mycorrhizae can help absorption water in soil solum deeper. Besides, it also save use nitrogen and phosphor fertilizers water-choked conditions. This research aimed to optimize dosage phosphorus growth rainfed lowland applied mycorrhizae. Methods: was carried out from April July 2019 with entisol D...

Scaevola aemula is a popular ornamental crop cultivated as a bedding plant or for hanging baskets. We characterized gas exchange properties of S. aemula ‘New Wonder’ in response to photosynthetically active radiation (PAR), carbon dioxide concentration, and leaf temperature. Net CO2 assimilation rate (A) was responsive to CO2, exhibiting a saturation when intercellular CO2 concentration (Ci) wa...
