Abstract

The Field trials on sunlower crop were conducted in different in states of India during the year from 2006 to 2008.The RSFPD, Government of India, DADF provided all inputs to conduct the tirals in the area under their juridiction to evaluate the suitable varieties of sunlower, their sowing season, irrigations vs rainfed conditions of cultivation including other agronomic package of practices. Government of India has strong feed and fodder development organization. There are several centrally sponsered schems like estabishment of fodder banks, development of forage crops through biotechnology research, minikits distribution in the country. Central government distributed latest variety seeds in the country through eight RSFPDs. The sunflower is a multi-purpose crop and may be good source of animal feeds as a un-conventional feed resource. Sunlower can be grown with forage crops also. RSFPDs organized sunflower trials in different states to evaluate sunflower production in northern and southern parts of India. The varieties and hybrids released by AICRP (Sunflower) for different regions were selected for field trials. India has tropical and subtropical climate from south to north, respectively. Tamilnadu and Maharastra face the tropical while, Haryana, Punjab and Uttar Pradesh experience a sub-tropical type of climate having February and March as spring season in northen India. All India released varieties Morden, GAUSUF-15, TNAUSUF-7, DRSF-108 and DRSF-113 were grown at Pantnagar in Uttranchal. Vaiety TNAUSUF, DRSF-108 and DRSF-113 performed better with seed yield (1720.6/1860.8/1802.4 kg/ha) respectively in irrigated conditons in rabi season at pantnagar. Variety GAUSUF and TNAUSUF-7 produced higher seed yield (1210.9 and 1160.1 kg/ha) in rainfed situations in kharif at pantnagar. This yield was significantly higher as compare to irriated condition in rabi 2007-8. Data shows that oil content (40.3, 38.5%) was higher in the seeds of cultivar DRFS-108. Maximum plant hieght was recorded in variety DRSF 108 (161.9, 159.6 cm) and head diameter (16.2, 14.9 cm) was higher in the variety DRSF-108 and 16.1/15.9 in TNAUSUF-7.
