Meher kuch moong raat bhar bhigokar geeli rui par rakhti hai. Do din mein chhote safed ankur jhaankte hain. Beej ankurit (germinate) ho gaya: naya paudha banna shuru ho gaya.

Beej ko ankurit hone ke liye kya chahiye? Meher chaar plate lagaati hai, ek baar mein ek cheez badalkar: sookhi rui (paani nahi), ubale-thande paani mein dube beej (hawa nahi), fridge mein beej (thanda), aur ek mein paani, hawa aur garmi.

Sirf aakhri plate mein ankur aate hain. Beej ko ankurit hone ke liye paani, hawa aur garmi chahiye. Shuru karne ke liye mitti ya roshni nahi chahiye: unke andar khaana jama hota hai. Ugne ke baad chhote paudhe ko badhte rehne ke liye dhoop aur mitti chahiye.

Kisaan beej tab kyun bote hain jab mitti nam ho aur mausam garam, bahut thande sookhe mausam mein kyun nahi?
