Nthawi zambiri, mutatha kugwiritsa ntchito feteleza wa nayitrogeni, phosphorous ndi potaziyamu, nthawi zambiri amakhudzidwa ndi zinthu monga acidity ya nthaka, chinyezi cha nthaka ndi tizilombo tating'onoting'ono ta nthaka, ndipo zimakhazikika ndi kutsekedwa, zomwe zimachepetsa mphamvu ya feteleza. Feteleza wa foliar amatha kupewa izi ndikusintha feteleza bwino. Feteleza wa foliar amapopera mwachindunji pamasamba popanda kukhudzana ndi nthaka, kupewa zinthu zoipa monga kutsekemera kwa nthaka ndi leaching, kotero kuti kugwiritsa ntchito kwake kumakhala kwakukulu ndipo kuchuluka kwa feteleza kumatha kuchepetsedwa.

Kadyedwe kake kwa mbeuyo

Zomera zomwe zilibe michere m'thupi zimakhala ndi mphamvu zotha kuyamwa zakudya. Ngati mbewuyo imakula bwino ndipo michere imakhala yokwanira, imayamwa pang'ono mutapopera feteleza wa foliar; apo ayi, idzayamwa zambiri.

Kugwiritsiridwa ntchito ndi mlingo wa Indole-3-butyric acid makamaka zimatengera cholinga chake komanso mtundu wa mbewu yomwe mukufuna. Zotsatirazi ndizomwe zimagwiritsidwa ntchito komanso mlingo wa Indole-3-butyric acid polimbikitsa mizu ya zomera:

Kupopera mbewu mankhwalawa masamba kukuyenera kusiyanasiyana malinga ndi masamba

⑴ masamba amasamba. Mwachitsanzo, kabichi, sipinachi, thumba la abusa, ndi zina zotero zimafuna nayitrogeni wambiri. Kupopera mbewu mankhwalawa ayenera makamaka urea ndi ammonium sulphate. Kupopera mbewu mankhwalawa ndende urea ayenera 1-2%, ndi ammonium sulphate ayenera 1.5%. Utsi 2-4 pa nyengo, makamaka kumayambiriro kwa kukula.
