Invloed van blaarvoeding op blominduksie en differensiasie van pekanneute
Deur Deon Claassen, Hortoloog, Agri Technovation Opbrengs bepaal deur die graad van alternerende drag asook blom- en neutafspening: Een van die grootste uitdagings wat pekanneut- produsente in die gesig staar, is die gewas se geneigdheid tot alternerende drag. Alterne-rende drag by pekanneute word gewoonlik gekenmerk deur een seisoen met baie swaar drag (’n sogenaamde aanjaar), gevolg […]

Hoe om jou opbrengs-raaisels te ontsyfer
Deur Carl van HeerdenHoof Landboukundige: GroenteAgri Technovation As die wêreldwye vraag na gewasse so vinnig styg as wat sommige kenners voorspel, sal die oesopbrengs in die volgende paar dekades vinniger moet styg. Beter tegnologieë sal ’n deurslaggewende rol speel om opbrengste te verhoog, terwyl omgewingsimpakte tot die minimum beperk moet word. In die besonder sal presisie-landboutegnologieë ’n […]
