“…The number of per plant had significantly affected by both nitrogen levels and application methods, while the interaction affect was non-significant. The finding are correlated to [9] who stated the nitrogen enhance the vegetative and reproductive growth of canola. Days to first flowering response was significant in cases of nitrogen levels and application methods, while the effect was non-significantly in case of interaction.…”

Use of imbalance fertilizers and its application methods may cause reducing crops productivity. Therefore the proper level of fertilizers and appropriate methods is required to sustain the productivity of crops and soil fertility. Different levels of Nitrogen and its application methods were used to improve the canola productivity. A field experiment was conducted at University of Agriculture, Peshawar research farm in 2015-16. Randomized complete block design in split plot arrangement was applied with four replicates. Application methods (Broadcast method, rows one side placement, rows both side placement and rows between) were allotted to main plots and N levels (40, 70 and 90 kg ha-1) were allotted to subplots. Experimental results exhibit that all the parameter were significantly (p ≤ 0.05) different; maximum days to emergence (9), maximum number of plant m-2 (32), maximum days to first flowering (97), maximum grain pod-1 (28), maximum 1000 grain weight (3.2 g), maximum grain yield (985 kg ha-1) were noted at plot that fertilized with 70 kg ha-1 N along with both side placement of rows. It can be concluded that N at 70 kg ha-1 and both side placement of rows produce a higher yield and yield attributes of canola.

“…Treatment (T-3) (40S + 100N) resulted in maximum contents on protein, N. and S. Authors concluded that a balanced N and S supply should be maintained for both quantity and quality of oil of Brassica genotypes. Jan et al [ 75 ] evaluated the effects of N and S levels and their methods of application on quality parameters of canola ( B. napus L. cv. “Bulbul-98”) taking into account four levels of S (0, 20, 40, and 60 kg ha −1 ) and three levels of N (80, 120, and 160 kg ha −1 ) and a control treatment (with both nutrients at zero level) applied either as a sole dose at sowing, in two split applications (half each at sowing and leaf rosette stages) or three split applications (one third each at sowing, leaf rosette stage, and early flowering).…”

Mineral nutrients are the integral part of the agricultural systems. Among important plant nutrients, nitrogen (N) and sulphur (S) are known essential elements for growth, development, and various physiological functions in plants. Oleiferous brassicas (rapeseed and mustard) require higher amounts of S in addition to N for optimum growth and yield. Therefore, balancing S-N fertilization, optimization of nutrient replenishment, minimization of nutrient losses to the environment, and the concept of coordination in action between S and N could be a significant strategy for improvement of growth and productivity of oleiferous brassicas. Additionally, positive interaction between S and N has been reported to be beneficial for various aspects of oilseed brassicas. The current paper updates readers on the significance of N and S for the improvement of plant growth, development, and productivity in detail. In addition, S-N nutrition-mediated control of major plant antioxidant defense system components involved in the removal and/or metabolism of stress-induced/generated reactive oxygen species in plants (hence, the control of plant growth, development, and productivity) has been overviewed.

“…Plants in 2013 produced higher amounts of GSs than that in 2012, which corresponded to the higher amount of background S availability in soil in 2013. Sulphur application increased the total amount of GSs in turnip rape (Kim et al, 2002), rapeseed ( Jan et al, 2010;Asare and Scarisbrick, 1995;Josefsson, 1970;Šiaudinis and Butkutė, 2013;Withers and O'Donnell, 1994), and broccoli (Rangkadilok et al, 2004;Schonhof et al, 2007;Vallejo et al, 2003;Zhao et al, 1997). The mean monthly temperatures during the plant reproductive development stage ( July and August) at Canning in 2012 and 2013 were similar, so it was difficult to determine the temperature effects on the GS formation in the present study.…”

Camelina [Camelina sativa (L.) Crantz] is an alternative oil crop that has potential in aquaculture and food production. However, glucosinolates (GSs) in camelina seed and meal constrain their application in human and animal consumption. Glucosinolates are plant secondary metabolites commonly found in the Brassicaceae family. The aims of this study were to determine whether nitrogen (N) alone or in combination with sulphur (S) application affected GS concentration in camelina seeds, as well as whether different genotypes differed in GS concentrations. Our results showed that the application of 25 kg S ha−1 significantly increased GS content compared with 0 kg S ha−1. Applied N rates were negatively correlated with the amounts of total and individual GSs when no S was applied. The low GS content with high N rates was probably due to a dilution effect of S content. Applied N rates did not affect the amounts of total and individual GSs when 25 kg S ha−1 was applied. Seed protein content was negatively correlated with the total GSs depending on growing season and genotype when no S was applied. The cultivar, Calena, had the highest amount of GSs among five genotypes. The results indicated that GSs in camelina can be manipulated by cultural management practices including N and S application.
