Tomates bio, guide de culture<\/h1>\n

\"Semences<\/p>\n

Lev\u00e9e<\/strong> : en 5-11 j en sol \u00e0 20\u00b0C (optimum entre 18-20\u00b0C le jour et 15\u00b0C la nuit).<\/p>\n

Nbre de graines\/g<\/strong> : 250-350.<\/p>\n

PMG<\/strong> : 3-4 g.<\/p>\n

Densit\u00e9 de plantation<\/strong> :
\nEn plein champ : 45×100 cm soit 18000 plants\/ha.
\nSous-abri : 45×90 cm soit 25000 plants\/ha.
\nPlein champ non-tuteur\u00e9 : 55×160 cm soit 13000 plants\/ha.<\/p>\n

Dates de semis et de r\u00e9colte<\/strong> :
\nAbri froid :
\nSemis<\/strong> de f\u00e9vrier \u00e0 mi-mars. R\u00e9colte<\/strong> : d\u00e8s juin.<\/span><\/p>\n

Plein champ :
\nSemis<\/strong> de mars \u00e0 mai. R\u00e9colte<\/strong> : juillet \u00e0 octobre.<\/span><\/p>\n

R\u00e9colte<\/strong> : environ 60 jours apr\u00e8s plantation et se prolonge jusqu’au d\u00e9but de l’automne.<\/p>\n

Besoin en NPK<\/strong> : N : 200 U, P : 100 U, K : 300 U\/ha.<\/p>\n

Apport<\/strong> : 20 \u00e0 30 t\/ha de fumier m\u00fbr ou 5 t\/ha de produit du commerce.<\/p>\n

Les tomates sont class\u00e9es en plusieurs calibres<\/strong> : 40 \u00e0 47 mm, 47 \u00e0 57 mm, 57 \u00e0 67 mm, 67 \u00e0 80 mm, >82 mm.<\/p>\n

Rendement th\u00e9orique<\/strong> : de 8 \u00e0 15 kg\/m\u00b2 en fonction de la vari\u00e9t\u00e9 et de la saison.<\/p>\n

Stockage<\/strong> : pour les vari\u00e9t\u00e9s anciennes, afin d\u2019\u00e9viter que les tomates se fendent, rangez-les collet \u00e0 l\u2019envers (vers le bas).<\/p>\n

\"Agrosemens,<\/p>\n

 <\/p>\n

Pratique culturale<\/h1>\n

La tomate appartient \u00e0 la famille des solanac\u00e9es.<\/strong> Originaire des pays tropicaux et des contreforts des Andes (Am\u00e9rique du Sud), la tomate n\u2019est produite que depuis 150 ans pour la consommation de ses fruits. Semez en mottes de 4×4\u00a0cm compos\u00e9es de terre humide et riche en humus. 8 semaines apr\u00e8s, repiquez les plantons en les enterrant de 10 cm en dessous du collet. Vous lui choisirez une exposition ensoleill\u00e9e, car elle affectionne la lumi\u00e8re et la chaleur.<\/strong> Vous favoriserez ainsi le d\u00e9veloppement de racines secondaires, dites adventives.<\/p>\n

Suivant les vari\u00e9t\u00e9s vous installerez des tuteurs avant m\u00eame la plantation. La tomate pr\u00e9f\u00e8re les terres l\u00e9g\u00e8res, meubles et fra\u00eeches<\/strong>. Un sol riche en terreau donne les plus beaux fruits : fumez donc votre terre en automne. Des arrosages r\u00e9guliers \u00e9vitent la coulure des fleurs, puis apr\u00e8s nouaison, l\u2019\u00e9clatement des fruits<\/strong>. Pensez-y ! Suivant les vari\u00e9t\u00e9s \u00e0 croissance d\u00e9termin\u00e9e ou ind\u00e9termin\u00e9e vous pourrez \u00e9liminer par une taille les tiges secondaires ou gourmands se formant entre l\u2019aisselle d\u2019une feuille et la tige principale.<\/p>\n

Les vari\u00e9t\u00e9s \u00e0 croissance d\u00e9termin\u00e9e \u00e9mettent seulement 4 ou 5 bouquets floraux. La s\u00e8ve va donc essentiellement dans ces 4 \u00e0 5 grappes et pas dans le feuillage. 8 \u00e0 10 semaines apr\u00e8s la plantation vous r\u00e9colterez des fruits jusqu\u2019aux premi\u00e8res gel\u00e9es.<\/p>\n

En cultures associ\u00e9es, afin d\u2019\u00e9viter la transmission de virus \u00e9ventuels, ne plantez pas de tomates \u00e0 c\u00f4t\u00e9 des l\u00e9gumineuses<\/strong> (haricots et pois), des choux rouges et des fenouils. Sa culture est \u00abam\u00e9lior\u00e9e\u00bb par le compagnonnage de plants d’aneth, de basilic, de menthe ou de souci.<\/strong><\/p>\n

Afin d\u2019\u00e9viter la transmission de maladies cryptogamiques (champignons) vous pouvez effeuiller le bas des pieds, avant la maturit\u00e9 du premier bouquet et puis tous les 15 jours.<\/strong> Pour lutter contre les n\u00e9ma- todes plantez entre vos tomates des \u0153illets d\u2019Inde et du basilic. En culture sous abri, l’introduction de ruche de bourdons permet d’assurer la pollinisation des fleurs.<\/p>\n
