$Book of Plants-$
Botany
Al-Dinawari is considered the founder of Arabic botany for his Kitab al-Nabat (Book of Plants), which consisted of six volumes. Only the third and fifth volumes have survived, though the sixth volume has partly been reconstructed based on citations from later works. In the surviving portions of his works, 637 plants are described from the letters sin to ya. He describes the phases of plant growth and the production of flowers and fruit.
Many of the Muslim early botanical works are lost, such as that of al-Shaybani (d.820), Ibn al-Arabi (d.844), Al-Bahili (d.845) and Ibn as-Sikkit (d.857), however, their works, are extensively quoted in later books by Abu Hanifa Al-Dinawari.

Parts of al-Dinawari's Book of Plants deals with the applications of Islamic astronomy and meteorology to agriculture. It describes the astronomical and meteorological character of the sky, the planets and constellations, the sun and moon, the lunar phases indicating seasons and rain, the anwa (heavenly bodies of rain) and atmospheric phenomena such as winds, thunder, lightning, snow, floods, valleys, rivers, lakes, wells and other sources of water.
$Earth sciences$
Parts of al-Dinawari's Book of Plants deals with the Earth sciences in the context of agriculture. He considers the Earth, stone and sands, and describes different types of ground, indicating which types are more convenient for plants and the qualities and properties of good ground.[1]
