Kam paani, majboot fasal: beej ki chhanti
Is saal kai jagah baarish bahut kam hui. Kya koi fasal aisi hai jo kam paani mein bhi khadi reh sake?
Socho pehle… phir dekho jawab
Haan! Bajra aur jowar jaisi faslein kam paani mein bhi ug jaati hain. Aur kisan saal-dar-saal un paudhon ke beej bachaate hain jo sookhe mein bhi tike rahe.
Har paudha thoda alag hota hai, jaise har bachcha alag hai. Sookhe saal mein kuch paudhe murjha jaate hain, kuch tike rehte hain.
Kyun beej chunna kaam karta hai? Kyunki paudhe apni khoobiyan beej ke zariye apne 'bachchon' ko dete hain. Majboot paudhe ke beej se aksar majboot paudha ugta hai. Isliye kisan aur scientists sabse achhe paudhon ke beej chunte hain.
Andhra Pradesh mein is saal June se August tak aadhe se bhi kam baarish hui, aur aadhe se zyada ilaakon mein sookha ghoshit hua. Aise samay mein kam paani wali fasal aur achhe beej kisanon ki badi madad karte hain.
