Effect of Sulphur on Productivity of Soybean in Front Line Demonstrations in the Indore District of Madhya Pradesh, India

The soybean is the important crop of Madhya Pradesh. The unbalanced uses of fertilizer have deteriorated the productivity of soybean in the region. The poor productivity of soybean is mainly due to imbalanced application of nutrients and use of traditional varieties. Sulphur is an essential plant nutrient for crop production. For oil crop producers, S fertilization is especially important because oil crops require more S than cereal crops. In view of this, twenty front line demonstrations (FLD) on soybean conducted by Krishi Vigyan Kendra, Indore during 2016-17 and 2017-18 to know the yield gaps between FLD’s and farmer’s field, extent of technology adoption. Results indicated under the improved practice soybean seed yield recorded was in range of 17.57 to 13.14 q/ha (average 15.98 q/ha) by improved package of practices over existing farmers practices. On average basis the technology gap of all the twenty demonstration was recorded of 6.32 q/ha. An extension gap ranging from 2.14 to 2.47 q/ha was found between FLDs demonstration and farmers practices. The average technology index was 31.60% for both the year. The result of economic analysis of soybean production revealed that front line demonstration recorded higher gross return Rs. 51,523 and net return Rs.27 421 with higher benefit cost ratio of 2.14.
