Gibberellic Acid GA3 ndi hormone yofunikira yomwe imatha kulimbikitsa kumera kwa mbewu. Gibberellic Acid GA3 yapezeka kuti imayambitsa jini mumbewu, zomwe zimapangitsa kuti njere zikhale zosavuta kumera pansi pa kutentha, chinyezi komanso kuwala koyenera. Kuphatikiza apo, Gibberellic Acid GA3 imathanso kukana zovuta pamlingo wina ndikuwonjezera kupulumuka kwa mbewu.

Pali mitundu yambiri ya feteleza wa masamba. Malingana ndi zotsatira zake ndi ntchito, feteleza wa masamba akhoza kufotokozedwa mwachidule m'magulu anayi: zakudya, zowongolera, zachilengedwe ndi zowonjezereka.

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.
