Technical information can also be obtained at the OMAF Field Crops Webpage at http://www.gov.on.ca/OMAFRA/english/crops/index.html . Referenced OMAF Publications include Publication 811 Agronomy Guide for Field Crops ($20), 812 Field Crop Protection Guide ($10), 75 Guide to Weed Control ($10), and 505 Ontario Weeds ($15). These can be obtained from your OMAF Resource Centre, or by calling the Publications Office at 888-466-2372. Corn Most of the corn crop across the province looks good. Nitrogen application should be complete and the window for weed control has essentially passed. The management window for this season’s corn crop has all but passed. On average crop heat unit accumulation across the province is near normal and the stage of much of the crop is in the expected V8-10 stage with 9-12 leaves emerged and bent over for this date. For London Ontario the 30 year normal CHU accumulation is 861 and presently in 2005, 869 have been recorded. Areas east and north are averaging ~ 50 CHU’s behind normal which is good considering the weather conditions experienced in May. Rainfall has been spotty but in general soil moisture is holding up well. The crop is entering the period of rapid growth. Forages Unpredicted rainfall caught a lot of recently cut hay in the swath but the recent rains have benefited regrowth in previously harvested fields.

32. Introduction - Agronomy Division Research in the special crops Lab focus on medicinal herbs, fiber crops, Timedependent dynamic models of taro harvest index (HI) were established. http://www.tari.gov.tw/ARI_E/Introduction_AD.htm

HOME INTRODUCTION Agronomy Division v Rice Breeding for high quality of japonica rice and conservation of rice genetic resources are major tasks for the rice program with an emphasis in high grain quality, diseases, insect pests, lodging resistance, and high yield characters. Tainung Nos. 67, 69, 71 and Tainung Sen Waxy No. 2 are the four important varieties registered by ARI. Tainung No. 67 released in 1978 and once occupied more than 75% of total rice acreage, is still very popular in Taiwan. A new variety Tainung No. 71, a taro-scented japonica rice with good grain and eating quality, is well accepted and growth with more than ten thousand hectares bringing in more than eight hundred million dollars extra benefits to the farmers. Rice Tainung No 71 (Yihchaun Aromatic Rice)¡GA middle plant height variety with good plant type and moderate resistance to many pests. The milled rice is short and round in shape, good appearance and excellent eating quality with taro-like fragrance. Yihchaun aromatic rice.
