Abstract
National soybean consumption in 2018 was not in balance with its production. One of factors affecting soybean production is location-specific improved varieties utilization. The research aimed to identify farmers’ considerations in responding improved soybean varieties and prospective lines. The research was conducted in KP Taman Bogo, East Lampung and BP3T at Tambak Ulang, South Kalimantan. Data collected presented into tables. A descriptive analysis used by calculating means and percentage value. The results showed that crop height, seed shape, drought resistance, and fall resistance were the dominant considerations for East Lampung farmers. South Kalimantan farmers chose growth type, flowering age, harvest age, pod color, non-breaking pod, leaf shape, seed color, wilting symptoms, pests and diseases resistance, fall resistance, and ease of sale variables. Of the ten lines and four Iletri’s improved soybean varieties, East Lampung farmers chose Grobogan for crop phisycal performance as priority I (37.9%) and II Tgm/933 (24,2%); while South Kalimantan farmers chose Tanggamus (23.3%), Tgm/Anj-910 (26,7%) and Tgm/Anj-933 lines (30%). For seed characteristics, 51.7% of East Lampung farmers chose Grobogan as priority I, while South Kalimantan farmers chose Tgm/Anj-931 line (30.0%). It is expected that by selecting location-specific improved varieties, farmers can increase soybean production, thereby increasing their income.
Highlights
National soybean consumption in Indonesia in 2016 reached 2.85 tons while its production was only 860 hundred tons
The research was conducted in KP Taman Bogo, East Lampung and Indonesian Agency of Integrated Agricultural Research and Development or BP3T at Tambak Ulang, Tanah Laut, South Kalimantan
Ten prospective lines of soybean, namely: (1) Tgm/Anj-933, (2) Tgm/Anj-931, (3) Tgm/Anj-910, (4) Tgm/Anj-932, (5) Tgm/Anj-909, (6) Tgm/Anj-991, (7) Tgm/Anj-957, (8) Tgm/Anj-908, (9) Tgm/Anj-995, (10) Tgm/Anj-919, and four improved soybean varieties, namely: (11) Tanggamus, (12) Anjasmoro, (13) Wilis, and (14) Grobogan were introduced to respondent farmers to be evaluated for soybean seeds preference
Summary
National soybean consumption in Indonesia in 2016 reached 2.85 tons while its production was only 860 hundred tons. The national soybean balance sheet experienced a deficit of 1.99 million tons. The national soybean consumption in 2018 reached 3.05 million tons, which was not in balance with national soybean production of 864 thousand tons, a deficit of 2.19 million tons. The demand on soybean is escalating in 2021 to around 2.6 million tons and causing an increase of deficit into 2.24 million tons [1]. Acidic dry-land has the potential for agricultural expansion in terms of soybean cropping. This land is widely spread throughout Indonesia apart from Java, including Sumatera, Kalimantan, Sulawesi, Maluku, and Papua [2]. Climate and precipitation that are vary causes the land to become acid due to intensive leaching [5]
