Abstract

Biostimulants plays an important role in the phytoremediation process of soil contaminated with hydrocarbon compounds. This experiment aims to determine the best treatment between N-fixing bacteria (BNF) and cow manure (CM) that can improve oil-polluted soil. The experiment was conducted in January-April 2019 at Kebun Percobaan Ciparanje Fakultas Pertanian Universitas Padjadjaran, Jatinangor, Sumedang, used a randomized block design method with four combinations (without BNF + without CM, Azotobacter sp. + without CM, without BNF + CM dose of 100% and Azotobacter sp. 4% + CM dose of 100%). The results showed there was not significant with control, except combination of without BNF + CM dose of 100% treatment could increase the population of Azotobacter sp. of 4.8 x 108 CFU/g, while Azotobacter sp. + without CM can increase the degradation of hydrocarbons and dry weight of ramie plants 0.1047 ppm/day and 40.433 g.

Abstract

Chili (Capsicum annum L) was one of the vegetable commodities that have a significant economic value. Farmland narrowed due to land conversion led to a shift of fertile agricultural lands into marginal lands such as saline land. This research aimed to determine respond of chili plant growth to salinity stress in Inceptisols. The experiment was conducted in August-October 2020 with located at Ciparanje Experimental field of Faculty of Agriculture, Padjadjaran University, Jatinangor District, Sumedang Regency. This research used randomized block design using four level treatment of NaCl concentration: 0 dS/m (a0), 2 dS/m (a1), 4 dS/m (a2), and 6 dS/m (a3). The result showed that there was no significant between treatment soil salinization of plant growth parameters like plant height and shoot root ratio but significant of number of leaves at 7 day after plant and canopy width at 28 day after plant on treatment salinization 6 dS/m.
