Abstract

Acid mineral soils are soils that have properties such as low pH, low cation exchange capacity, low base saturation, low organic C, high Al saturation and high phosphorus fixation. The technical problem with acid soils is the low level of soil fertility which affects plant productivity. The purpose of this study was to determine the dynamics of the microb population on acid soils. The soil used was two Typic Hapludults from Neglasari Jasinga Village, Bogor and Padasuka Maja Lebak Village with different levels of Al-dd saturation. Soil microb population included total microbes, total sulfate reducing bacteria and total Acidithiobacillus ferrooxidans. Acid soils from Jasinga and Lebak have soil conditions with acidic pH, low organic C content. For acid soils from Jasinga, the highest total of microbes was at a depth of 0-35 cm and the highest total of Acidithiobacillus ferrooxidans was at a depth of 0-35 cm. Whereas for acid soils from Lebak, the highest total of microbes was at a depth of 0-15 cm and the highest total of Acidithiobacillus ferrooxidans was at a depth of 15-40 cm. There was no population of sulfate-reducing bacteria in acid soils from Jasinga and Lebak.

Abstract

Red durian plants have the potential to be developed because they have high economic value. Red durian plants are propagated conventionally in two ways, namely through seeds and shoot grafts. Propagation using shoot graft creates a new problem for red durian farmers, namely a decrease in fruit production on the parent plant due to large amounts of scion. One alternative to the propagation of red durian seeds without damaging the parent plant can be done by using tissue culture techniques. The explants used in this study was durian callus. The callus was grown on B5 media treated with a plant growth regulator combination in the form of TDZ consisting of six treatments, namely 0, 0.4, 0.8, 1.2, 1.6 ppm and BA consisting of five treatment, namely 0, 0.3, 0.6, 0.9, 1.2 ppm. This research was conducted to determine the best dose of combination treatment of tidiazuron (TDZ) with BA in the formation of shoots from red durian callus through tissue culture. The results showed that at the age of 6 months after culture, red durian callus had a color change from yellow to green in the TDZ treatment 1.6 ppm + BA 1.2 ppm.

Abstract

This research was conducted to determine the effectiveness of  legin and straw mulch treatment on the growth and yield of black soybean plants. This research was conducted from June 2020 to September 2020, at Ngablak, Kemuning, Ngargoyoso, Karanganyar Regency with an altitude of 750 m above the sea. This study used a factorial method with randomized complete block design (RCBD) consisting of two factors. The first  factor is giving straw mulch E (E0 = without pulsing, E1 = with straw mulch). The second  factor is the various doses of legin H (H0 = without legin, H1 = 7,5 kg / g seeds, H2 = 15 g / kg seeds, H3 = 22,5 g / kg seeds). The data obtained were analized using analysis of variance followed by Duncan's multiple Range test (DMRT) at the 5% level. The results showed that the treatment of straw mulch (E) had a very significant effect on all parameter observed. The treatment of various doses of legin and the interaction between mulching and legin were not significantly effect  for the five parameters observed .Combination of E1H2 treatment (with straw and legin mulch at a dose of 15 g / kg of seed)had highest yield weight of dry biomassa per plant 36.42 g, weight of dry seed per plant 27.84 g and weight of dry seeds per plot 479.12 g. The treatment of E0H0 (without straw mulch and without legin) had the lowest yield to all parameter observed.
