Application of different fertilizers on morphological traits of dill (Anethum graveolens L.)

Abstract

BackgroundThe aim of this study was to evaluate the effects of nitroxin biofertilizer and chemical fertilizer on the growth, yield, and essential oil composition of dill. The experiment was conducted under field condition in randomized complete block design with three replications and two factors.ResultsThe first factor was the concentrations of nitroxin biofertilizer (0%, 50%, and 100%) of the recommended amount (1 l of biological fertilizer for 30 kg of seed). The second factor was the following chemical fertilizer treatments: no fertilizer (control) and 50 and 100 kg ha−1 urea along with 300 kg ha−1 ammonium phosphate. Different characteristics such as plant height, number of umbel per plant, number of umbellet per umbel, number of grain per umbellet, 1,000 seed weight, grain yield, biological yield, and oil percentage were recorded. According to the results, the highest height, biological yield, and grain yield components (except harvest index) were obtained on biological fertilizer. The results showed the highest essential oil content detected in biological fertilizer and chemical fertilizer. Identification of essential oil composition showed that the content of carvone increased with the application of biofertilizers and chemical fertilizers. The results indicated that the application of biofertilizers enhanced yield and other plant criteria in this plant.ConclusionsGenerally, it seems that the use of biofertilizers or combinations of biofertilizer and chemical fertilizer could improve dill performance in addition to reduction of environmental pollution.

Effects of drying temperature and ethanol concentration on bipolar switching characteristics of natural Aloe vera-based memory devices

“…All samples exhibit a broad absorption band centered at 3424 cm À1 , which is due to the stretching of -OH groups, a characteristic of carbohydrate monomers including mannose and uronic acid. [50][51][52][53][54][55] The absorption band at 2922 cm À1 can be assigned to the symmetrical and asymmetrical C-H stretching of aliphatic -CH and -CH 2 groups. The absorption band at 1743 cm À1 is characteristic of CQO stretching, indicating the presence of carbonyl groups in the Aloe vera samples.…”

Combined bio-chemical fertilizers ameliorate agro-biochemical attributes of black cumin (Nigella sativa L.)

“…The chain-breaking has a correlation with the amount of antioxidants that are boosted by biofertilizers. Therefore, the measurement of these parameters together can be an interesting way to estimate the antioxidant capacity of a compound 74 .…”

A Modified Polysaccharide‐Based Hydrogel for Enhanced Osteogenic Maturation and Mineralization Independent of Differentiation Factors

“…The prominent peak at 1725 cm −1 corresponds to carboxylic acid and indicates incorporation of AA onto TKP‐backbone at 1:20 mole ratio. The 1420 cm −1 peak corresponds to symmetric stretches of COO – indicating the incorporation of AA on to TKP‐backbone . Further, increase in intensity of alkyl stretching frequency at 2928 cm −1 can be attributed to the increase in grafting percentage into TKP‐backbone with increasing mole ratio of AA.…”
