Tema: Oestyd AGRICULTURAL Tips for Autumn and Early Winter 2019 Late rain this season and late planting, will result in a late harvesting. The first frost, which usually occurs from around 5 April, could already have occurred in certain places.  By Petrus van Staden Senwes Senior Agronomist and Boet van Zyl Senwes Senior Agricultural Economist T WHEAT he rain needed for summer planting came relatively late and certain districts could not plant summer crops. The good rain which occurred from mid-Jan- uary, improved soil water content to the extent that the soil profile is water-filled. All these factors result in producers look- ing differently at wheat for the winter. Should own seed be retained for wheat planting, it is important to afford special attention to the factors which ensure good plant density. Seed must be sifted, followed by a seed treatment. Take the preliminary tillage and management pro- gramme with safety periods into account. Planter technology must be at an optimum level. COVER CROPS Should it have been possible to plant maize or sunflower at a late stage, the normal quantity of plant residue should be available as protection against wind erosion. If not, the planting of wheat as a 10 SENWES SCENARIO | AUTUMN 2019 cash crop and/or cover crops for feed or prevention of wind erosion, are strongly recommended. Available technology offers a range of crops, cultivars and mixes, which can be used for specific purposes, for example: • To prevent wind erosion - choose a cultivar which is a fast and tall grower. It should be sprayed at the height of 50 cm. • As source of winter feed for cattle or sheep. Enough material can be left to prevent wind erosion should effective management practices be applied. • In a rotation system it is part of con- servation agriculture. The long-term advantages for soil health should be utilised. It has a regenerative effect in the soil which could buffer physiolog- ical stress resulting from fluctuating climate conditions. CATTLE The relatively late rain could result in a difficult winter, even for extensive cattle farmers, and the following should be attended to. • Provide a good protein lick as soon as the first frost occurs. • Water troughs should always be clean, particularly when crop residue is uti- lised. The grain in the water creates a fermentation process, which results in an unpleasant taste. • Should winter grazing be problematic as far as volume is concerned, get rid of old and surplus cattle timeous- ly. A few rand less at this stage is worth more than a hide in September/ October. Manage your cash flow and take care of your core herd. • Sell all young and growing animals if you are already experiencing a feed problem and should there be no feed reserves for the winter. • Should crop residue be used as graz- ing, use the time to do maintenance to fences and water supply points. FOR THE MAIZE FARMER WITH A CATTLE COMPONENT: The season is characterised by late planting and the occurrence of hail. Maize which was damaged by hail or the occurrence of frost before having reached physiological maturity, can be utilised by cutting it for silage purposes or by being used as grazing. Take the directions for the handling and utilisation of such plant material into account to ensure success. Should it not be possible to use it in an own cattle component, it could be sold.
