For information and descriptions of recommended, commercially available varieties, growers are referred to the variety guides produced annually by Cotton Seed Distributors Ltd... Once purchased, a grower can maintain seed of a variety with Plant Breeder's Rights (PBR) protection... The area of cotton planted under irrigation should be determined by: the ability to complete an irrigation cycle every 7-10 days during peak flowering of the crop the total amount of water available, as moisture stress has a large effect on yield...

Take home message Low temperatures and frost caused losses up to 100% in many 2009 chickpea crops Chickpeas won't hold a pod until average daily temperature reaches15C Temperature records in the canopy can explain why flowers and pods abort Plant at the optimum time to maximize WUE and yield and minimise frost damage.. The low temperature effects on chickpea reproduction were exacerbated by frosts on 28 Sep and (in some places) 8 Oct 09... Conclusions Low temperatures and frost caused losses up 100% in many 2009 chickpea crops Chickpeas don't form fertile flowers and keep pods until average daily temperature reaches15C Temperature readings, preferably collected in the canopy, can be used to explain why flowers and pods abort Planting at the optimum time maximises WUE and yield and can minimise frost damage..

The chance of a La Ni a developing in 2007 is thought to be higher than the long-term average, which is about one in five, or 20 per cent... La Ni a events tend to follow El Ni os; the 2006-07 El Ni o weakened somewhat earlier than normal giving time for a La Ni a to begin developing during the critical March to June period; and a large pool of cold sub-surface water remains in the central to eastern tropical Pacific Ocean and is starting to affect surface temperatures in the region... BOM climate meteorologist Grant Beard says that although central to eastern Pacific sea-surface temperatures have remained close to average during March, following the rapid cooling that took place during January and February, the remaining large pool of cold sub-surface water could indicate a La Ni a event...

Optimising Corn population to maximise the potential returns for supplementary irrigation.. Net return was calculated as the gross return (price by yield) minus the growing season variable costs (full list of costs in Appendix 2)... Net return for Hycorn 345 IT was maximised at 50 000 plants/ha screenings were not calculated into the yield...
