\u00cen domeniul agriculturii, urm\u0103rirea randamentului optim al culturilor este o provocare perpetu\u0103 pentru fermierii din \u00eentreaga lume. De\u0219i \u00een\u021belepciunea conven\u021bional\u0103 atribuie adesea pierderile de randament unor factori evidenti \u0219i condi\u021biilor meteorologice nefavorabile, exist\u0103 un fenomen mai subtil \u0219i mai evaziv, cunoscut sub numele de Pierdere Fantom\u0103 a Randamentului.<\/p>\n

Se refer\u0103 la reducerea inexplicabil\u0103 a randamentului culturilor, care nu poate fi atribuit\u0103 direct factorilor conven\u021bionali precum d\u0103un\u0103torii, bolile sau condi\u021biile meteorologice nefavorabile. Spre deosebire de amenin\u021b\u0103rile evidente care se manifest\u0103 vizibil, aceasta opereaz\u0103 sub suprafa\u021b\u0103, adesea sc\u0103p\u00e2nd de la detectare p\u00e2n\u0103 c\u00e2nd impactul s\u0103u devine evident \u00een timpul recolt\u0103rii.<\/p>\n

Conform unui raport al Organiza\u021biei pentru Alimenta\u021bie \u0219i Agricultur\u0103 (FAO), se estimeaz\u0103 c\u0103 30% din produc\u021bia agricol\u0103 global\u0103 se pierd \u00een fiecare an din cauza diver\u0219ilor factori, inclusiv acesta.<\/p>\n

Acest fenomen pune la \u00eendoial\u0103 \u00een\u021belegerea conven\u021bional\u0103 a limitelor de randament \u0219i impune o examinare mai nuan\u021bat\u0103 a ecosistemului agricol. Prin urmare, \u00een\u021belegerea sa este crucial\u0103 pentru fermieri \u0219i agronomi, deoarece scoate la iveal\u0103 factori care pot trece neobserva\u021bi, dar exercit\u0103 o influen\u021b\u0103 substan\u021bial\u0103 asupra randamentelor culturilor.<\/p>\n

Prin recunoa\u0219terea \u0219i abordarea acestor elemente ascunse, practicile agricole pot fi rafinate, iar productivitatea general\u0103 poate fi \u00eembun\u0103t\u0103\u021bit\u0103.<\/p>\n

Pierderea fantom\u0103 a randamentului la porumb<\/h2>\n

Porumbul, una dintre cele mai importante culturi din lume, joac\u0103 un rol esen\u021bial \u00een produc\u021bia alimentar\u0103 global\u0103. Cu toate acestea, fermierii se confrunt\u0103 cu numeroase provoc\u0103ri \u00een optimizarea randamentelor de porumb, un factor semnificativ fiind pierderea necontrolat\u0103 a randamentului.<\/p>\n

Este vorba despre pierderea randamentului poten\u021bial care apare atunci c\u00e2nd porumbul este l\u0103sat s\u0103 se usuce natural pe c\u00e2mp dup\u0103 un anumit punct. Se \u00eent\u00e2mpl\u0103 deoarece boabele de porumb continu\u0103 s\u0103 respire \u0219i s\u0103 piard\u0103 \u00een greutate pe m\u0103sur\u0103 ce se usuc\u0103, reduc\u00e2ndu-\u0219i masa \u0219i calitatea. Nu este vizibil cu ochiul liber, dar poate avea un impact semnificativ asupra profiturilor dumneavoastr\u0103.<\/p>\n

\"Pierderea<\/p>\n

Potrivit lui Eric Frank, un seedman de la Channel Seedman din Frankfort, Indiana, este vorba de \u201co sc\u0103dere a randamentului care se \u00eent\u00e2mpl\u0103 la porumb atunci c\u00e2nd nu \u00eencepe\u021bi recoltarea mai devreme. Se \u00eent\u00e2mpl\u0103 deoarece permite\u021bi culturii s\u0103 se usuce \u00een mod natural p\u00e2n\u0103 la un anumit punct \u00eenainte de recoltare. C\u00e2nd pierde at\u00e2t de mult\u0103 umiditate \u00een c\u00e2mp, practic se canibalizeaz\u0103 pu\u021bin.\u201d<\/p>\n

Cum contribuie respira\u021bia nucleului la aceasta?<\/h2>\n

Acest lucru se \u00eent\u00e2mpl\u0103 deoarece boabele sunt \u00eenc\u0103 vii dup\u0103 ce au atins stratul negru \u0219i continu\u0103 s\u0103 respire \u0219i s\u0103 consume zaharurile \u0219i amidonul stocate. Aceast\u0103 activitate metabolic\u0103 reduce masa boabelor \u0219i scade greutatea lor specific\u0103 \u0219i calitatea.<\/p>\n

Respira\u021bia boabelor este procesul prin care boabele folosesc oxigen \u0219i glucoz\u0103 pentru a produce energie, dioxid de carbon \u0219i ap\u0103. Este o activitate metabolic\u0103 normal\u0103 care are loc pe parcursul etapelor de dezvoltare \u0219i maturare a boabelor.<\/p>\n

\"Cum<\/p>\n

Totu\u0219i, respira\u021bia bobului nu se opre\u0219te la maturitatea fiziologic\u0103, c\u00e2nd se formeaz\u0103 stratul negru la v\u00e2rful bobului. Boabele r\u0103m\u00e2n vii p\u00e2n\u0103 c\u00e2nd sunt uscate p\u00e2n\u0103 la un nivel de umiditate suficient de sc\u0103zut (\u00een jur de 15%) pentru a fi ucise. \u00cen aceast\u0103 perioad\u0103, bobul continu\u0103 s\u0103 respire \u0219i s\u0103 piard\u0103 substan\u021b\u0103 uscat\u0103.<\/p>\n

C\u00e2t randament po\u021bi pierde din cauza asta?<\/h2>\n

Aceasta depinde de mai mul\u021bi factori, cum ar fi hibridul, vremea, tipul de sol \u0219i momentul recolt\u0103rii. Cu toate acestea, unele studii au ar\u0103tat c\u0103 poate varia de la 5 la 15 bu\u0219eli pe acru sau mai mult.<\/p>\n

De exemplu, \u00een 2020, agronomul de teren Missy Bauer de la Farm Journal a efectuat o parcel\u0103 de testare \u00eentr-un c\u00e2mp irigat cu un hibrid. Ea a recoltat o parte din c\u00e2mp pe 23 septembrie, c\u00e2nd nivelul de umiditate era de 27,9%, iar restul c\u00e2mpului pe 30 octombrie, c\u00e2nd nivelul de umiditate era de 18,4%. Ea a constatat c\u0103 recolta timpurie a produs cu 15,6 bushels pe acru mai mult dec\u00e2t recolta t\u00e2rzie, la 214,2 fa\u021b\u0103 de 198,6 bushels pe acru.<\/p>\n

\"C\u00e2t<\/p>\n

Totu\u0219i, o regul\u0103 general\u0103 este c\u0103 \u00eencepe s\u0103 apar\u0103 atunci c\u00e2nd umiditatea porumbului scade sub 13% - 16%. Conform unor studii, poate varia de la 0,5% la 1,6% per punct de umiditate sub 15%. Aceasta \u00eenseamn\u0103 c\u0103 un fermier care recolteaz\u0103 porumb la o umiditate de 12% \u00een loc de 15% ar putea pierde p\u00e2n\u0103 la 4,8% de randament doar din aceast\u0103 cauz\u0103.<\/p>\n

Unele studii ulterioare au raportat pierderi de randament cuprinse \u00eentre 5 \u0219i 15 bu\u0219eli pe acru, cu date de recoltare mai t\u00e2rzii. De exemplu, un studiu de cinci ani realizat \u00een Nebraska a constatat c\u0103 randamentul a sc\u0103zut \u00een medie cu 9,1 bu\u0219eli pe acru odat\u0103 cu recoltarea mai t\u00e2rzie, indiferent de modificarea umidit\u0103\u021bii boabelor sau de durata de timp dintre datele de recoltare. \u00cen mod similar, un studiu realizat \u00een Michigan a ar\u0103tat un avantaj mediu de randament de 8,9 bu\u0219eli pe acru pentru o recoltare mai timpurie.<\/p>\n

Cum s\u0103 o m\u0103sori?<\/strong><\/p>\n

Cea mai bun\u0103 metod\u0103 de a m\u0103sura acest lucru este de a compara randamentele porumbului recoltat la diferite niveluri de umiditate \u00een acela\u0219i c\u00e2mp. Acest lucru se poate face prin recoltarea unei por\u021biuni din c\u00e2mp devreme, c\u00e2nd porumbul este \u00eenc\u0103 umed (\u00een jur de 25% p\u00e2n\u0103 la 30% umiditate), \u0219i a unei alte por\u021biuni mai t\u00e2rziu, c\u00e2nd porumbul este uscat (\u00een jur de 15% sau mai pu\u021bin).<\/p>\n

Diferen\u021ba de randament dintre cele dou\u0103 por\u021bii reprezint\u0103 pierderea care a avut loc pe c\u00e2mp. De exemplu, dac\u0103 porumbul recoltat timpuriu a produs 200 bu\/acru, iar porumbul recoltat t\u00e2rziu a produs 190 bu\/acru, atunci pierderea de randament va fi de 10 bu\/acru sau 5%.<\/p>\n

Factorii care contribuie la pierderea randamentului fantom\u0103<\/h2>\n

Iat\u0103 c\u00e2\u021biva dintre factorii ascun\u0219i sau mai pu\u021bin evidenti care contribuie la pierderea randamentului:<\/p>\n

1. Dimensiunea \u0219i forma miezului:<\/strong> Hibrizii moderni de porumb au boabe mai mari \u0219i mai ad\u00e2nci dec\u00e2t cei mai vechi, ceea ce \u00eenseamn\u0103 c\u0103 au mai mult\u0103 mas\u0103 de pierdut \u00een timpul respira\u021biei.<\/p>\n

Potrivit agronomului de teren Missy Bauer de la Farm Journal, boabele de ast\u0103zi au \u00een medie \u00eentre 70.000 \u0219i 76.000 pe bushel, comparativ cu 90.000 \u00een trecut. Aceasta \u00eenseamn\u0103 c\u0103 fiecare boab\u0103 are un impact mai mare asupra randamentului final \u0219i c\u0103 acesta poate fi mai semnificativ cu genetica mai nou\u0103.<\/p>\n

2. Con\u021binutul de umiditate al boabelor:<\/strong> Con\u021binutul de umiditate al boabelor determin\u0103 c\u00e2t\u0103 ap\u0103 pot pierde \u00een timpul respira\u021biei. Cu c\u00e2t con\u021binutul de umiditate este mai mare, cu at\u00e2t rata de respira\u021bie este mai mare \u0219i poten\u021bialul de pierdere a randamentului.<\/p>\n

Potrivit specialistului \u00een semin\u021be de la Channel 3, Eric Frank, problema \u00eencepe s\u0103 apar\u0103 atunci c\u00e2nd umiditatea boabelor scade sub 16%. El recomand\u0103 recoltarea porumbului cu o umiditate cuprins\u0103 \u00eentre 20% \u0219i 25% pentru a evita pierderea excesiv\u0103 \u00een greutate \u0219i calitate pe c\u00e2mp.<\/p>\n

3. Condi\u021bii meteorologice:<\/strong> Condi\u021biile meteorologice din perioada de uscare pot afecta rata de respira\u021bie \u0219i pierderile de randament. Temperaturile ridicate, umiditatea sc\u0103zut\u0103, v\u00e2ntul \u0219i lumina soarelui pot cre\u0219te evaporarea apei din boabe \u0219i pot accelera pierderea \u00een greutate.<\/p>\n

\"Factorii<\/p>\n

\u00cen schimb, temperaturile sc\u0103zute, umiditatea ridicat\u0103, ploaia \u0219i norii pot \u00eencetini procesele de evaporare \u0219i respira\u021bie \u0219i pot reduce pierderile de randament. Cu toate acestea, aceste condi\u021bii pot cre\u0219te \u0219i riscul de mucegai, boli \u0219i daune provocate de insecte, ceea ce poate reduce \u0219i randamentul \u0219i calitatea porumbului.<\/p>\n

4. Momentul recolt\u0103rii:<\/strong> Momentul recolt\u0103rii este un factor crucial care determin\u0103 c\u00e2t de mult apare \u00eentr-o cultur\u0103 de porumb. Recoltarea prea devreme poate duce la costuri ridicate de uscare \u0219i la o greutate specific\u0103 mai mic\u0103, \u00een timp ce recoltarea prea t\u00e2rzie poate duce la pierderi excesive \u0219i la o calitate mai sc\u0103zut\u0103 a boabelor.<\/p>\n

Momentul optim de recoltare depinde de mai mul\u021bi factori, cum ar fi maturitatea hibridelor, reducerile la silozurile de cereale, prognoza meteo, condi\u021biile de pe teren \u0219i disponibilitatea echipamentelor. Frank \u00eei sf\u0103tuie\u0219te pe fermieri s\u0103 \u00ee\u0219i monitorizeze \u00eendeaproape terenurile \u0219i s\u0103 \u00ee\u0219i ajusteze planurile de recoltare \u00een consecin\u021b\u0103.<\/p>\n

\u00centre timp, fermierii se pot confrunta cu condi\u021bii nefavorabile care le \u00eent\u00e2rzie sau le \u00eentrerup planurile de recoltare, cum ar fi ploaia, grindina, \u00eenghe\u021bul sau z\u0103pada. Aceste evenimente pot deteriora integritatea tulpinii \u0219i pot cre\u0219te riscul de c\u0103dere a \u0219tiftului, c\u0103dere a \u0219tiftului sau infec\u021bie cu mucegai, ceea ce poate reduce \u0219i mai mult randamentul \u0219i calitatea porumbului.<\/p>\n

Cum s\u0103 o evit\u0103m sau s\u0103 o reducem? Recoltarea timpurie!<\/h2>\n

Cea mai bun\u0103 modalitate de a evita pierderile este recoltarea porumbului la nivelul optim de umiditate \u0219i utilizarea metodelor de uscare controlat\u0103. Recoltarea porumbului la un nivel de umiditate mai ridicat (\u00een jur de 20% - 25%) poate ajuta la p\u0103strarea greut\u0103\u021bii \u0219i calit\u0103\u021bii boabelor, precum \u0219i la reducerea pierderilor pe c\u00e2mp cauzate de c\u0103derea \u0219tiule\u021bilor, c\u0103derea tulpinilor, deteriorarea insectelor, cre\u0219terea mucegaiului \u0219i contaminarea cu micotoxine.<\/p>\n

Cu toate acestea, recoltarea porumbului umed necesit\u0103 \u0219i instala\u021bii adecvate de uscare \u0219i depozitare pentru a preveni alterarea \u0219i deteriorarea calit\u0103\u021bii. Metodele de uscare controlat\u0103, cum ar fi uscarea natural\u0103 cu aer sau uscarea la temperatur\u0103 sc\u0103zut\u0103, pot ajuta la reducerea deterior\u0103rii \u0219i contrac\u021biei boabelor \u00een timpul procesului de uscare.<\/p>\n

\"Cum<\/p>\n

\u00cen plus, fermierii ar trebui s\u0103 ia \u00een considerare factorii economici implica\u021bi \u00een recoltarea porumbului umed fa\u021b\u0103 de porumbul uscat. Ace\u0219tia includ reduceri sau prime la silozurile de cereale pentru con\u021binutul de umiditate, costurile sau economiile de uscare, costurile sau economiile de depozitare \u0219i poten\u021bialele pierderi sau c\u00e2\u0219tiguri de randament sau calitate.<\/p>\n

Prin evaluarea acestor factori \u0219i utiliz\u00e2nd date fiabile din propriile c\u00e2mpuri sau din surse locale, fermierii pot lua decizii informate cu privire la momentul recolt\u0103rii porumbului \u0219i la modul de uscare eficient\u0103 \u0219i efectiv\u0103.<\/p>\n

O alt\u0103 modalitate este alegerea hibrizilor care au o bun\u0103 rezisten\u021b\u0103 la boli \u0219i d\u0103un\u0103tori care pot afecta rezisten\u021ba tulpinii \u0219i reten\u021bia \u0219tiule\u021bilor. De asemenea, pute\u021bi utiliza practici agronomice care promoveaz\u0103 cre\u0219terea \u0219i dezvoltarea s\u0103n\u0103toas\u0103 a plantelor, cum ar fi fertilizarea adecvat\u0103, controlul buruienilor, irigarea \u0219i gestionarea d\u0103un\u0103torilor.<\/p>\n

Poate PYL afecta \u0219i alte culturi?<\/h2>\n

Da, poate afecta diferite culturi, dar nu pe toate \u00een acela\u0219i mod. Poate d\u0103una culturilor cu un con\u021binut ridicat de umiditate atunci c\u00e2nd sunt complet dezvoltate \u0219i au nevoie de ceva timp pentru a se usca pe c\u00e2mp. Cu toate acestea, unele culturi sunt mai expuse riscului dec\u00e2t altele, \u00een func\u021bie de semin\u021bele lor, de modul \u00een care sunt... respira<\/span>, \u0219i mediul \u00eenconjur\u0103tor.<\/p>\n

Lua\u021bi soia, de exemplu. Este mai pu\u021bin probabil s\u0103 aib\u0103 o problem\u0103 major\u0103 de PYL \u00een compara\u021bie cu porumbul. Acest lucru se datoreaz\u0103 faptului c\u0103 soia are un con\u021binut de umiditate mai mic atunci c\u00e2nd este gata de recoltare (aproximativ 50% comparativ cu 70% pentru porumb) \u0219i se usuc\u0103 mai repede pe c\u00e2mp (aproximativ 10 zile comparativ cu 30 de zile pentru porumb).<\/p>\n

Totu\u0219i, dac\u0103 soia nu este recoltat\u0103 p\u00e2n\u0103 c\u00e2nd nu are un con\u021binut de umiditate mai mare de 13%, aceasta poate totu\u0219i pierde \u00een greutate \u0219i calitate din cauza respira\u021biei, destr\u0103m\u0103rii sau infect\u0103rii cu ciuperci.<\/p>\n

Gr\u00e2ul, pe de alt\u0103 parte, este mai expus riscului dec\u00e2t soia. Acest lucru se datoreaz\u0103 faptului c\u0103 gr\u00e2ul are un con\u021binut de umiditate mai mare la momentul recolt\u0103rii (aproximativ 60% comparativ cu 50% pentru soia) \u0219i dureaz\u0103 mai mult s\u0103 se usuce pe c\u00e2mp (aproximativ 20 de zile comparativ cu 10 zile pentru soia).<\/p>\n

Gr\u00e2ul poate pierde p\u00e2n\u0103 la 10% din greutatea sa dac\u0103 nu este recoltat p\u00e2n\u0103 c\u00e2nd nu are un con\u021binut de umiditate mai mare de 14%, din cauza respira\u021biei, destr\u0103m\u0103rii, \u00eencol\u021birii sau bolilor.<\/p>\n

Alte culturi precum orzul, ov\u0103zul, secara, sorgul, floarea-soarelui, canola \u0219i lucerna pot suferi, de asemenea, de PYL. C\u00e2t de mult sunt afectate depinde de compozi\u021bia culturii, de gene, de modul \u00een care este \u00eengrijit\u0103 \u0219i de vreme. De aceea este esen\u021bial ca fermierii s\u0103 urm\u0103reasc\u0103 nivelul de umiditate al culturilor lor \u0219i s\u0103 le recolteze \u00een cel mai bun moment pentru a evita pierderile inutile.<\/p>\n
