Abstract

The low production of shallots due to low productivity caused mainly by the not suitability of varieties, land and climate for optimal production. This research aims to study the response of varieties in mulch treatments and different of planting seasons to the productivity of shallots in the lowlands. The study was conducted in the lowlands, Tapin district, South Kalimantan at the rainy and dry season 2017. Three shallots varieties of Batu Ijo, Bauji and Bima Brebes were planted in the 2017 rainy season which were treated with plastic mulch and without mulch. The three varieties were planted again without mulch treatment in dry season 2017. The results showed that the average mulch treatment in the rainy season increased the productivity of shallots (8.02 t/ha) higher than without mulch (6.77 t/ha). In the treatment without mulch, the yield of Bauji variety (9.12 t/ha) was higher than Batu Ijo (7.10 t/ha) and Bima Brebes (4.08 t/ha) variety. The average productivity of shallots planted in the dry season was 12.37 t/ha higher than the rainy season 6.77 t/ha. Bauji variety was more adaptive to be planted in the rainy or dry season than Batu Ijo and Bima Brebes varieties in the lowlands.
