The Soybean Processors Association of India today lowered the country soybean output estimate for 2017-18 (Oct-Sep) to 8.35 mln tn from 9.15 mln tn pegged earlier. The association has revised its estimate downwards due to lower production in key growing regions of Madhya Pradesh, Maharashtra and Rajasthan. Soybean output in Madhya Pradesh, the largest grower, was pegged at 4.2 mln tn in 2017-18, down from 5.4 mln tn in the previous year. Production is also seen lower at 2.9 mln tn in Maharashtra, against 3.6 mln tn last year, it said. The oilseed production in Rajasthan was pegged at 750,000 tn, down from 981,000 tn. Soymeal exports in 2017-2018 have been pegged at 1.3 mln tn, down from 2.0 mln tn last year. The estimated soybean arrival by January at 5.3 mln tn against 4.3 mln tn a year ago while stocks with farmers, plants and traders were seen at 4.5 mln tn.
