gehun ki pehli sinchai kab kare: CRI stage ki samajh
Rabi season mein gehun ki pehli sinchai bahut mahatvapurn hoti hai kyunki isse plant ki root development aur tillering par seedha asar padta hai. gehun ki pehli sinchai kab kare ka jawab aapko ICAR ki advisory se milta hai, jo kehte hai ki irrigated wheat ke liye pehla paani 18‑20 din ke CRI (Critical Root Initiation) stage par dena chahiye ICAR RABI Advisory.
CRI stage kya hota hai aur kyun zaroori hai?
CRI stage ka matlab hai Critical Root Initiation, jab seed germination ke baad 18‑20 DAS (Days After Sowing) tak jadain sabse tezi se badhti hain. Is stage mein paani dene se:
- Root depth badhti hai, jo baad ke sukh ke samay paani ki uplabdhata ko maintain karta hai.
- Tillering (kallan) ka process tezi se hota hai, jo aage ke yield ko directly influence karta hai.
- Plant stress kam hota hai, isliye disease resistance bhi improve hoti hai.
2026 ke Rabi wheat ke liye recommended irrigation schedule
ICAR ke hisaab se, agar aapke paas 4 irrigations ki suvidha hai to aapko yeh schedule follow karna chahiye:
- First irrigation: 22 DAS (CRI stage) – yahi pehli sinchai ka samay hai.
- Second irrigation: 45 DAS (tillering stage).
- Third irrigation: 85 DAS (spike formation ya flowering stage).
- Fourth irrigation: 105 DAS (grain filling stage).
Late sown wheat ke liye pehli sinchai 28‑30 DAS tak delay ho sakti hai, lekin phir bhi CRI stage ko miss nahi karna chahiye ICAR guidance.
Rainfed vs irrigated wheat: pehli sinchai ka farq
Rainfed wheat ko pehli bar soil ki residual moisture se hi lagbhag 10‑15 October tak sow karna chahiye, lekin jab tak paani ki supply ho, tab bhi CRI stage par paani dena faydemand hota hai. Irrigated wheat ke liye first irrigation ka timing bahut strict hota hai, kyunki poora crop almost entirely irrigated hota hai FAO India 2026 outlook.
Practical tips for first irrigation
1. Soil moisture check: Hand trowel se 10‑15 cm tak soil ko check karein; agar dry ho to turant paani dein.
2. Water amount: 20‑25 mm water uniformly apply karein, taaki sabhi plants ko equal moisture mile.
3. Timing: Subah ke 6‑8 baje ya shaam ke 5‑7 baje irrigation karna behtar hota hai, kyunki evaporation kam hoti hai.
4. NEER timer ka istemal: KrishiVerse ka NEER timer aapko exact DAS ke hisaab se irrigation alerts dega, isse aap CRI stage miss nahi karenge. KrishiVerse NEER timer
What if water is scarce?
Jab paani ki kami ho, ICAR kehta hai ki agar sirf ek irrigation ka mauka ho to use 40‑42 DAS par dena chahiye, jo ki CRI ke baad thoda late stage hai lekin phir bhi yield loss ko minimize karta hai ICAR recommendation. Aise situation mein:
- Mulching se soil moisture retain karein.
- Deficit irrigation techniques adopt karein, jaise ki 15‑20 din ka interval NITI guidelines.
Aksar Pooche Jaane Wale Sawal (FAQ)
Q: Gehun ki pehli sinchai kab karni chahiye agar maine November 5 ko beej boya?
A: Agar aapne early November mein sow kiya hai to pehli sinchai 22‑25 DAS, yaani roughly 25‑30 November ko deni chahiye, jo CRI stage ke andar aata hai.
Q: Late sowing (December 10) par pehli sinchai ka samay kya hoga?
A: Late sowing ke liye first irrigation 28‑30 DAS tak delay ho sakti hai, lekin fir bhi CRI stage ko target karna zaroori hai.
Q: Agar sirf ek hi irrigation ka mauka milta hai to use kab dena chahiye?
A: Sirf ek irrigation ke liye 40‑42 DAS par paani dena behtar hota hai, taaki plant ke critical growth phase ko support mil sake.
Q: NEER timer kaise madad karta hai?
A: NEER timer aapke sowing date ko record karta hai aur DAS ke hisaab se alerts bhejta hai, isse aap CRI stage miss nahi karte.
Q: Rainfed wheat ke liye pehli sinchai ki zaroorat hoti hai ya nahi?
A: Rainfed wheat ko residual soil moisture se start kiya jata hai, lekin jab tak paani available ho, CRI stage par supplemental irrigation dena faydemand hota hai.
