Wax wakhti badan oo waraabinta ah ma macno samaynayo haddii aysan ahayn jadwal sax ah. Beero badan ayaa biyo aad u badan ku ridda ama lumiya xilliga muhiimka ah ee dhirta. Jadwal saxan wuxuu kor u qaadaa wax-soosaarka 25–40% iyada oo isticmaala isla qadarka biyaha. Watering at the wrong time wastes water and stunts crops. Most farms over-irrigate at the wrong stage and under-irrigate at critical growth windows. A proper schedule lifts yields 25–40% with the same total water. الري في الوقت الخاطئ يهدر الماء ويضرّ المحاصيل. الجدولة الصحيحة ترفع الإنتاج 25–40% بنفس كمية الماء. Kumwagilia kwa wakati usio sahihi hupoteza maji.
Saddexda Su'aalood ee Muhiimka ahThe Three Key Questionsالأسئلة الثلاثة الأساسيةMaswali Matatu Muhimu

Tijaabi gacanta: hadii ciidda 30 cm hoose ay qalalan tahay, waraabi.When? — When plants have used 50% of the soil's available water. Hand-test: if soil at 30 cm depth is dry to the touch, irrigate.متى؟ — عندما تستهلك النباتات 50% من ماء التربة. اختبر باليد.Lini? — Mimea ikitumia 50% ya maji ya udongo.

- Sidee? — Drip, sprinkler, ama furrow. Habka kasta wuxuu leeyahay xaqiijin gaar ah.How? — Drip, sprinkler, or furrow — each method has its own efficiency.كيف؟ — تنقيط أو رش أو غمر.Vipi? — Drip, sprinkler, au mifereji.
Baahida Biyaha ee Dalagga (ETc)Crop Water Need (ETc)احتياج المحصول للماءMahitaji ya Maji
ETc waa biyaha ay dhirtu isticmaasho maalintii. Waxay ku xidhan tahay: cimilada (heerkulka, qoyaanka, dabaysha), xilliga koritaanka, iyo nooca dalagga (Kc factor). Tusaale: yaanyada xilliga ubaxa, ETc = 6 mm/maalin. Dhul 1 hektar = 60 m³ biyo maalintii. ETc is daily crop water use. It depends on climate (temperature, humidity, wind), growth stage, and crop type (Kc factor). Example: tomatoes at flowering, ETc = 6 mm/day. One hectare = 60 m³ water/day. ETc هو استهلاك المحصول اليومي للماء. مثال: طماطم بالإزهار = 6 ملم/يوم = 60 م³/هكتار يومياً. ETc ni matumizi ya maji ya zao kwa siku.
Xilliyada Muhiimka ah ee DalaggaCritical Growth Stagesمراحل النمو الحرجةHatua za Ukuaji
Marka biyaha la dhameeyo xilligan, wax-soosaarku waxaa lagu khasaaray 30–60% — xitaa hadii wax-soosaarku xilliyada kale uu fiicnaa: Water stress at these stages cuts yield 30–60% — even if other stages were well watered: إجهاد المياه في هذه المراحل يقلل الإنتاج 30–60%: Ukosefu wa maji katika hatua hizi hupunguza mavuno 30–60%:
- Galleyda — xilliga ubaxa iyo balaadhaynta ifrale (silking + grain fill).Maize — silking and grain fill.الذرة — التزهير وامتلاء الحبوب.Mahindi — kutoa miche na kujaza nafaka.
- Yaanyada — xilliga ubaxa iyo koritaanka miraha.Tomato — flowering and fruit set.الطماطم — التزهير وعقد الثمار.Nyanya — kutoa maua na kuzaa.
- Basasha — xilliga bulbka kororsiga.Onion — bulb formation.البصل — تكوين البصلة.Vitunguu — kutengeneza vitunguu.
- Bariiska — xilliga ubaxa (panicle initiation).Rice — panicle initiation.الأرز — بدء السنابل.Mchele — kuanza panicle.

1) Hab gacanta: Qaad ciid 30 cm hoose. Marka aad gacanta lagu gargooyo: way isku qaban tahay → biyo kaafi ah; way kala daadan → biyo waraabi. 2) Tensiometer: qalab muujiya cadaadiska biyaha ciidda. Ku saari ciidda 20–40 cm; marka muujiyaha hoosaada 30–50 kPa, waa wakhtigii waraabinta. 3) Saadaalka cimilada + ETc: Adigoo isticmaalaya FAO CropWat ama mobile app, xisaab biyaha la rabo asbuuc kasta. 1) Hand-feel method: Take soil from 30 cm depth. If it holds shape, moisture is sufficient; if it crumbles, irrigate. 2) Tensiometer: measures soil water tension at 20–40 cm depth; irrigate at 30–50 kPa. 3) Weather forecast + ETc: use FAO CropWat or a mobile app to plan weekly water need. 1) باليد: فحص التربة 30 سم. 2) Tensiometer: اروِ عند 30–50 kPa. 3) التوقعات + ETc: استخدم CropWat. 1) Kwa mkono. 2) Tensiometer. 3) Utabiri + ETc kwa CropWat.
Wakhtiga MaalintaTime of Dayوقت اليومWakati wa Siku
Aroor hore (5–9 saac) ama fiidkii dambe (16:00–19:00). Wakhtigan, uumiga (evaporation) waa hoose, oo dabayshu waa fudud. Iska ilaali waraabinta duhurka iyo habeenkii dambe (sababtoo ah caleemaha qoyaan habeenkii waxay keenaan fungaska). Early morning (5–9 AM) or late afternoon (4–7 PM) are best. Evaporation is low and wind is calm. Avoid midday (water loss) and late night (wet leaves invite fungus). الصباح الباكر أو العصر. تجنب الظهر والليل. Asubuhi mapema au jioni. Epuka mchana na usiku.
Khaladaadka Caadiga ahCommon Mistakesالأخطاء الشائعةMakosa
- Waraabin maalin kasta wax yar — keenta xididada gaaban iyo dhir daciif ah.Watering a little every day — produces shallow roots and weak plants.قليل يومياً = جذور ضحلة.Kidogo kila siku = mizizi mifupi.
- Iska indho-tirin saadaasha roobka — waxaad bixisaa biyo bilaash ah maalin yar ka dib roobka.Ignoring rain forecasts — wastes water just before rainfall.تجاهل التوقعات يهدر الماء.Kupuuza utabiri.
- Hal jadwal oo loo isticmaalo dhammaan dalagga — yaanyada iyo qamadiga ma laha baahi isku mid ah.One schedule for all crops — tomato and wheat have very different needs.جدول واحد لكل المحاصيل خطأ.Ratiba moja kwa mazao yote.
