Dhan (Rice) Bharat ki sabse mahatvapurn aur purani faslon me se ek hai. Yeh humare khane ka main hissa hai aur desh ke lakhs kisanon ke liye aaj bhi rozgaar aur aay ka mukhya srot hai. Agar dhan ki kheti scientific aur sudhare hue tareeke se ki jaye, to kisan kam mehnat me zyada upaj aur achha munafa kama sakte hain.

Dhan Ki Kheti Ke Liye Upyukt Mausam

Dhan ek garmi aur nami pasand crop hai. Iske liye monsoon season sabse accha hota hai.

• Temperature: 20°C se 35°C beech ka taapmaan dhan ke liye ideal hai.
• Rainfall: 100–150 cm barish is fasal ke liye perfect hoti hai.
• Sunlight: Poore din me 4–5 ghante ki direct dhoop bahut zaruri hai.

Agar irrigation facility available ho, to dhan ko saal bhar bhi ugaya ja sakta hai jaise Rabi aur Summer crops.

Dhan Ki Kheti Ke Liye Upyukt Mitti

Dhan ke liye chikni aur paani rukhne wali mitti sabse acchi mani jati hai.

• Clayey loam soil ya alluvial soil is crop ke liye best hoti hai.
• pH level: 5.5 se 7.0 tak hona chahiye.
• Mitti me paani rukna chahiye, kyunki dhan ke paudhe ko lagataar nami chahiye hoti hai.

Kheti se pehle zameen me goobar ki khaad ya compost milane se upaj aur mitti ki fertility badhti hai.

Beej Ka Chayan aur Taiyaari

Achhi upaj ke liye beej ka selection sabse important step hai.

1. Beej ki matra: Ek hectare ke liye 30–40 kg beej kaafi hota hai.
2. Beej ka ilaj: Beej ko 24 ghante paani me bhigo kar, fir fungicide (jaise Bavistin) se treat karna chahiye.
3. Beej ki variety: Apne area ke mutabik improved varieties jaise PR-114, IR-64, Sarjoo-52, ya Pusa Basmati chun sakte ho.
4. Nursery preparation: Beej pehle nursery me boya jata hai, jahan se 20–25 din me paudhe transplant karne layak ho jate hain.

Khet Ki Taiyaari aur Paudha Ropan

• Khet ko 2–3 baar hal chalakar achhe se leveled kar lo.
• Paudhe lagane se pehle field me paani bhar do taaki puddling (mitti ko slushy banana) ho jaye.
• 20–25 din purane paudhe transplant karo.
• Spacing: Line se line 20–25 cm aur plant se plant 15–20 cm doori rakhni chahiye.
• Transplant karte waqt field me halka paani hona chahiye.

Sinchai (Irrigation) Ka Management

Dhan ke paudhe ko lagataar paani chahiye hota hai, lekin paani ka atirikt jamaav nuksaandeyak ho sakta hai.

• Transplanting ke turant baad pehli sinchai karo.
• Phir har 7–10 din me sinchai karte raho.
• Flowering aur grain-filling stage par paani ki kami bilkul na hone do.
• Katayi se 15 din pehle paani nikal do taaki field dry ho jaye.

Aajkal drainage aur alternate wetting-drying system ka istemal karke paani ki bachat bhi ki ja sakti hai.

Khaad aur Poshan Prabandhan

Zyada upaj ke liye balanced nutrition zaruri hai.

• Organic manure: 10–15 ton goobar ki khaad per hectare.
• Fertilizer dose: 100 kg Nitrogen, 50 kg Phosphorus aur 50 kg Potash per hectare.
• Nitrogen ko 3 parts me do – ek transplanting ke baad, ek tillering stage par aur ek flowering ke time.
• Zinc deficiency ke liye 25 kg Zinc Sulphate per hectare apply karo.

Isse dhan ke paudhe healthy rahenge aur grains bhare hue milenge.

Rog aur Keet Prabandhan

Dhan ki fasal me kai tarah ke rog aur keet lagte hain, jaise:

• Stem borer: Paudhe ke andar ghus kar nuksaan karta hai. Neem oil spray ya Chlorpyrifos se control karo.
• Brown Leaf Spot: Is rog me patton par daag ban jate hain. Mancozeb spray karo.
• Bacterial Leaf Blight: Copper oxychloride spray se control hota hai.
• Weeds (ghas-phus): Transplanting ke 20 din baad Butachlor ya Pendimethalin spray karna faydemand hai.

Faslon Ki Dekhrekh aur Upaj Badhane Ke Tips

1. Time-to-time weeding aur hoeing karo taaki nutrients sirf paudhon ko milen.
2. Field me bird perches lagao taaki natural pest control ho.
3. SRI (System of Rice Intensification) method apnao – isse kam paani me zyada upaj milti hai.
4. Organic methods jaise vermicompost aur biofertilizers ka use karna long-term me profitable hota hai.

Katayi aur Upaj

• Dhan ki fasal 110–140 din me ready ho jati hai (variety ke hisab se).
• Jab grains hard ho jayein aur 80–85% spikelets yellow ho jayein tab katayi karein.
• Harvesting ke baad dhan ko 12–14% moisture par sookha lena chahiye.
• Average upaj: 50–70 quintal per hectare, lekin improved varieties aur proper management se 90 quintal tak mil sakti hai.

Lagat aur Munafa

• Cost of cultivation: ₹30,000 – ₹45,000 per hectare (depends on irrigation aur fertilizer use).
• Income: ₹80,000 – ₹1,20,000 per hectare tak asani se ho sakta hai.
• Agar basmati ya hybrid variety ugai jaye, to profit aur bhi badh jata hai.

Conclusion

Dhan ki kheti ek traditional aur profitable fasal hai, jo har kisaan ke liye steady income ka source ban sakti hai. Bas kuch basic cheezon ka dhyan rakho — sahi beej ka selection, paani ka proper management, aur timely rog control.

Agar modern methods jaise SRI technique, organic inputs aur drip irrigation apnaye jayein, to dhan ki upaj aur quality dono badh jati hai.

Isliye aaj ke smart kisan ke liye dhan ki kheti sirf rozi-roti ka zariya nahi, balki ek smart agribusiness opportunity bhi hai.
