EFFECT OF PARENTAL NUTRIENT MANAGEMENT ON SEED GERMINABILITY OF TURNIP

To study the effects of fertilization of turnip (Brassica rap L.) plants with organic, biological, and chemical fertilizers on the produced seed germinability and seedling quality of turnip,a laboratory experimentwas conducted. First a field experiment was conducted with 15 different fertilizer treatments then produced seeds in each plot were used for laboratory experiment.The results showed that integration application of vermicompost, biological fertilizer and 25% of the required chemical fertilizer produced the best results in terms of seed germination percentage and seedling vigor. The quality of the seeds produced in this treatment was far higher than those produced in non-fertilized control plots or any other fertilization treatment. The results showed the combination of organic and biological fertilizers can lead to lowering the need of chemical fertilizers while improving the seed quality in turnip.
