How To Apply Chemical Fertilizers To Sunflowers
In addition, Goel. Helianthus annuus,.) at South Valley Area. Biofertilizers are the formulation of living microorganisms, which are able to fix atmospheric nitrogen and convert insoluble phosphorus to available one for the use of plants. The effect of biofertilizers on phosphorus percentage showed that no differences was found between the control and the same treatment plus biofertilizers, while highly significant increase in total P content of sunflower plants was recorded with all biofertilizers treatments plus 100 chemical fertilizer ( Table. (2006), who stated that in Helianthus annuus var.

Only the BL and MF treatments showed 1,000 seed weight values statistically higher than the control treatment, considering both plants without and with mycorrhization ( Table 3 ). T4 NPK (75 of full dose) vermicompost (2.5 t ha1). Figure 3 shows the values of relative mycorrhizal dependency (RMD) of the sunflower plants as a function of the treatment studied. The lower values of LWR of plants fertilized with LB, CU, and MF compared to the control indicate that sunflower plants under fertilization showed more efficient export of the material produced in the leaves to other organs of the plant, which is a favorable phenomenon. The total amount is more important than the percentage and the solution volume. Some climate factors were collected and analyzed.
LB: liquid biofertilizer, CU: cow urine, MF: mineral fertilizer, and C: unfertilized treatment - control.

This increase was also observed for the values of stem diameter; however, significant differences only occurred 95 days after sowing ( Figure 1b ).
Higher values of LA were observed in the MF, LB, and CU treatments (17.32,.07, and.54 dm2/plant, respectively which were significantly higher than in the control treatment (6.55 dm2/plant).
The Multi-KB can be combined with any pesticide/fungicide needed at this timing.
(1995), also working with sunflower, found that the RGR was high at the beginning of the cycle and reduced to zero at physiological maturity, due to gradual growth of tissues such as flowers and fruits. However, in plants with AMF, LWR values were significantly higher in the control treatment compared to the LB, CU, and MF treatments only as of 65 days after seeding. Growth parameters Figure 1a and 1b shows the data of plant height and stem diameter at different times during the sunflower plant cycle. Fasciculatum AMF in these treatments, compared to plants without mycorrhization ( Table 3 resulting in significantly higher levels of P and K in shoot dry matter. Fasciculatum, and from.0 (control) to 107.1 g/plant (MF) in plants with mycorrhization.
At present we are using chemical fertilizers in great quantities to compensate the deficiency of nutrients in soil 93 cmolc kg1 treatments, compared to the other treatments studied. Although the LB and CU treatments have lower levels.
Treatment combinations and design of experimental field The treatments used were as follows: T1 Full recommended dose of chemical fertilizers (100:50:50, that is 100 kg ha1 N:50 kg ha1 P:50 kg ha1 K). All the detailed pre and post-harvesting soil characteristics of this experiment were previously discussed in our published article ( Mondal., 2015 ). Soil EC is considered low; however, treatments with LB and CU increased EC by 600 and 680, respectively, compared to the control treatment due to the input of nutrients added by liquid biofertilizer and cow urine ( Table 1 ) in soil without the inoculation. There was a gradual increase in LA with increased time under cultivation, with maximum values at 95 days after sowing, in all treatments ( Figure 1d ).
