عنوان المقالة:تأثير مستويات مختلفة من السماد النتروجيني والفوسفاتي في النمو الخضري والمحتوى الكيميائي لنبات اليوكا . L aloifolia Yucc EFFECT DIFFERENT LEVELS OF NITROGEN AND PHOSPHATE FERTILIZER ON THE VEGETATIVE GRWOTH AND CHEMICAL CONTENT OF YUCCA ALOIFOLIA L.
The present study was carried out in laths house to study the effect of four
levels of fertilizer (0.0, 1.0, 1.5 and 2.0) g as ammonium sulphate (21% N) and
four levels of Phosphate fertilizer (0.0, 0.5, 1.0, 1.5) g as tri-super Phosphate (45%
P2O5) per pot diameter 30 cm, mixed with soil surface on the vegetative growth and
chemical content of Yucca aloifolia L. plants. The results refers that all studies
parameters affected significantly by Nitrogen fertilization and Phosphate
fertilization and the interaction between them on the concentration (2.0 gm/pot N
with 1.5 gm/pot P) which total increased on height stem and leave number and stem
diameter 13.44 cm and 11.61 leave and 2.98 cm in the end of study. While leaves
area of plant and percent of chlorophyll and Nitrogen and Phosphor 2577.88 cm2
and 60% and 5.37% and 0.77% respectively in the end of study.
