Production potential of summer sesame varieties in relation to dates of sowing under north Gujarat agro-climatic conditions

摘要

Effect of dates of sowing of sesame was seen at Sardarkrushinagar during 2007. Sesame crop sown on 15th February provided maximum net returns and B:C ratio (BCR) followed by 1st March sowing. Sesame variety Guj Til 2 gave maximum net profit and BCR. The proper time of sowing can have distinct effect on growth and eventually on yield of summer sesame. Some evidences indicated that sowing sesame on 12th February produced significantly higher seed and stalk yields with higher oil content as compared toearly sowing in January (Patil et a/., 1992). For exploitation of yield potential of the summer sesame, it is important to maintain optimum plant stand. Besides this, variety is another important factor for increasing productivity of the crop. There aremany varieties of sesame recommended for kharif season, but meager information is available on sesame varieties suitable for summer season in North Gujarat region. Keeping this in view, the present investigation was undertaken to identify the suitable varieties of sesame for summer season besides their optimum time of sowing.
