Abstract Temperature hike, moderate to severe water stress, land suitability and choice of suitable varieties, changes in sowing and harvesting dates are major limiting factors of wheat productivity in Vindhya Plateau Zone. In order to assess the site specific performance of wheat cultivars with improved production technologies, Krishi Vigyan Kendra Sagar conducted 31 farmers’ participatory trials during 2008–09 to 2012–13 at different locations of limited irrigated areas. The improved limited irrigated wheat cultivars viz. JW 3020, JW 3211, HI1531 and JW 3173 with recommended practices i.e. seed rate, seed treatment, line sowing, recommended dose of fertilizers and proper weed management were comprised. The control plots were farmers practices (use of old variety C-306 and poor crop management practices). The findings of the experiment revealed that there was a technological gap between recommended and existing practices. All the wheat varieties i.e. JW 3020, JW 3211, HI 1531 and JW 3173 performed very well in all the locations as compare to farmers practice. The wheat varieties yielded 23.30 q/ha marketable yield over farmers practice (17.40q/ha). Increase in yield between wheat cultivars was ranging 23.08–47.98 per cent with a mean per cent increase of 31.62 as compared to traditional farming practices. This huge variation in yield was due to changes in weather, differences in land fertility in an area wise and differences in farmers’ practices in different area. The average net profitability of worth Rs 22173.00/ha with benefit cost ratio 3.23 was recorded in assessed plots, while Rs 15410.00/ha with benefit cost ratio of 2.68 were obtained in existing practices. The suitable wheat varieties with recommended technologies showed a significant increase in yield over farmers practice and higher income too.
