Kutunza Shamba

Sehemu hii tutazungumzia jinsi ya kutunza shamba la mahindi ambapo tutagusia mambo makuu manne (4) ambayo ni; nyasi na magugu shambani, mbolea, wadudu shambani, pamoja na matumizi ya kemikali shambani. Mambo haya manne yamefafanuliwa zaidi hapa chini.

Phosphorous Deficiency

Wadudu:

Dalili: 1. Majani kuwa ya zambarau au mekundu mapema 2. Ncha za majani kufa na kubadilika kuwa na rangi ya kahawia iliyokolea 3. Masikio ya mhindi kwenye mahindi yaliyoathirika yanakuwa madogo na mara nyingi hupinda na kuwa na mistari ya punje za mahindi ambayo haifanani

Kumbuka: 1. Hutokea pale ambapo kuna baridi, kuna majimaji mengi au kuna ukavu mwingi, kupenya kusiko sawa kwa mizizi ya mahindi kwenye udongo ulioshikamana sana na mizizi kuathiriwa na wadudu, zana za kilimo au kemikali za shamba 2. Tumia mbolea za kuweka kwenya mashina (Nitrogen, Phosphorus, na Potassium) katika kiwango kinachoshauriwa (400kg/ha)
