Agronomic and physiological assessment of nitrogen use, uptake and acquisition in sunflower
A field experiment was conducted to study the effects of N fertilization on uptake,accumulation/remobilization, use efficiency and yield of sunflower grown in alluvial plains ofnorthwestern India comprising four hybrids (PSH 996, PAC 3789, PSH 569 and SH 3322)and five N levels (Control, 40, 80, 100 and 120 kg N ha-1) in split-plot design with threereplications. Increased N fertilizer rates sign...
متن کاملeffect of micronutrient fertilizers on sunflower growth and yield in drought stress condition
sunflower (helianthus annus l.) is the most important between oil plants in iran. the objective of this study was to evaluate the effects of micronutrients application on the sunflower yield under drought stress. this experiment was carried out at golmakan agriculture research station (iran) in 2005 that using a split plot randomized complete block design with four replications. irrigation was ...
متن کاملAssessment of cadmium uptake and nutrient content in sunflower plants grown under Cd stress
Sunflower plants were grown on soil contaminated with several levels of Cd (from 0.3 to 15 mg Cd kg/soil). Cd and nutrient (Cu, Zn, Fe, Ca, K, Mg) contents were evaluated in root and aboveground biomass during the vegetative growth period (from the emergence of the cotyledon leaves to the flower bud phase). An overall increase of Cd content was found in the plants during the growing cycle. Sign...
متن کاملZinc and Boron Fertility to Optimize Physiological Parameters, Nutrient Uptake and Seed Yield of Sunflower
Field research was conducted at Students Farm, Sindh Agriculture University, Tandojam, Pakistan, during 2005 and 2006. The sunflower variety HO-1 was treated with 0-0, 101.5, 10-2, 15 -1.5, 15-2.0, 201.5 and 202.0 Zn-B kg ha. A basal dose of N, P, and K was applied at the rates of 90, 45 and 45 kg ha respectively across Zn-B treatments. The increase in Zn and B fertility from 10-1.5 to 20-2 kg ...
متن کاملΜetal Uptake by Sunflower (Helianthus annuus) Irrigated with Water Polluted with Chromium and Nickel
The water aquifers of the regions of Asopos River in Viotia and Messapia in Evia (Greece) have been contaminated with hexavalent chromium (Cr (VI)) and bivalent nickel (Ni (II)). Given that these areas are the two biggest tuber producing regions of Greece, in our previous work, the cross-contamination of the food chain with these two heavy metals was quantified. In the present study, the potent...
