Vihenge
Wakati kutimiza mahitaji ya chakula ya idadi inayoongezeka bado ni wasiwasi mkubwa ulimwenguni, zaidi ya theluthi moja ya chakula hupotea au kupotea katika shughuli za mavuno. Kupunguza upotezaji wa mavuno, haswa katika nchi zinazoendelea, inaweza kuwa suluhisho endelevu la kuongeza upatikanaji wa chakula, kupunguza shinikizo kwa maliasili, kuondoa njaa na kuboresha wakulima & rsquo; maisha. Mazao ya nafaka ni msingi wa chakula kikuu katika mataifa mengi yanayoendelea, na hushughulikia upotezaji mkubwa wa mavuno kwa msingi wa kalori kati ya bidhaa zote za kilimo. Kiasi cha 50% & ndash; 60% ya nafaka zinaweza kupotea wakati wa hatua ya kuhifadhi kwa sababu tu ya ukosefu wa ufanisi wa kiufundi. Matumizi ya njia za kuhifadhi kisayansi zinaweza kupunguza hasara hizi hadi 1% & ndash; 2%.
- Kupunguza Upotezaji wa Mavuno ya Wavu, Vyakula, 2017
Hasara za mavuno zinaweza kuepukwa sana. Utafiti wa wakulima ulionyesha kuwa kwa asilimia 44 ya wahojiwa kuepukwa kwa upotevu wa nafaka imekuwa mabadiliko mazuri zaidi yaliyoletwa na kuletwa kwa silos. Matumizi ya silika imesaidia kuongeza usalama wa chakula kwa siku 30 & ndash; siku 35 kwa mwaka.
Mmiliki wa silo anaweza kuokoa zaidi au kupata zaidi. Mara tu baada ya mavuno, wakati usambazaji ni mkubwa katika masoko ya ndani na vile vile mijini, bei ya mahindi ni ya chini kabisa. Walakini, mtu yeyote ambaye anaweza kuhifadhi mahindi kwa usalama kwa miezi michache kabla ya kuuza anaweza kutegemea bei ya juu, au kinyume chake akiba kwa kutolazimika kununua wakati bei ya soko iko juu. Wakati wa mavuno, kati ya Novemba na Februari, karibu asilimia 80 ya wakulima huuza mahindi yao badala ya kuyahifadhi kwenye silo. Katika kipindi muhimu kabla ya mavuno yajayo, kati ya Machi na Julai, hali hiyo imebadilishwa, na asilimia 73 inauza mahindi tu yaliyohifadhiwa kwenye silo.

- Abstract, Toxins, 2017 Fusarium fungi are common plant pathogens causing several plant diseases. The presence of these molds in plants exposes crops to toxic secondary metabolites called Fusarium mycotoxins. The most studied Fusarium mycotoxins include fumonisins, zearalenone, and trichothecenes....
