Technology of microbial utilization to accelerate the oxidation of pyrite followed by leaching (bioleaching) has the potential to resolve problems in land management of actual acid sulphate soil. The research aims to obtain a bioleaching technology package that can improve the productivity of the actual acid sulfate soil. The experiment was conducted on tidal swamp land that has soil type of actual acid sulfate at Wana Raya sub-district, district Batola, South Kalimantan, in July - November, 2014. The study was designed by using strip plot with three replications. The treatment consisted of two factors, namely application of an oxidizing microbial pyrite and leaching amount (intensity). The main plot consisted of (P0) without leacing (naturally), (P1) six times leaching , (P2) eight times leaching, and (P3) 12 times leaching. Subplot consisted of (M0) without oxidizing microbial pyrite, (M1) with oxidizing microbial plant used in this study is Inpara 3 of rice variety. Observations were made on soil pH, oxidizing bacteria pyrite, growth of rice plants (plant height and number of tillers) and rice yield. The results showed that the main problem of actual acid sulfate land studied is a high soil acidity (pH of 3.44). Influ-ence of leaching was greater than microbial application on crop yields. Application of the pyrite oxidizing bacterial and leaching eight times gave the best influence on the growth and yield of rice plants.

Accumulator Plant

Silicon (Si) is one of the important things for rice growth. The importance of Si relates to increased rice yield, increased resistance to disease and resistance to falling. The rice is an accumulator plant of Si which requires Si for its growth. However, the Si in soil is continually decreased therefore the additional Si is needed intothe soil. Trass is one of the natural materials containing Ca and Si, therefore it can be used as a Si fertilizer. This study aims to determine levels of soil Si, straw, husk, and growth in rice. This research consisted of three types of soil, Oxisol, Inceptisol and Vertisol as the main plot and 7 doses of burnt fuel namely 0 (D0); 1.25 (D1); 2.5 (D2); 3.75 (D3); 5 (D4); 7.5 (D5); 10 (D6) g kg-1 of soil as subplots. The treatment which is using in this research is a combination of the two factors and repeated 3 times 63 unit experiments were obtained. The results showed the Trass significant concerning to Si in the husk and Si of the soil. Vertisol gives the highest number of panicles of 27 and Si in the straw of 12.75 mg kg-1.

Okra (Abelmoschus esculantus) L. Moench), is an important vegetable that grows in the tropical and sub-tropical parts of the world. Okra plants contain very high nutritional value (at 100 g of young okra fruit containing 35 g of calories, 89.6 g of water, 6.4 g of carbohydrates, 1.9 g of protein, 0.4 g of fat, 1.2 g of fiber, 0 , 7 g of minerals). In Indonesia, okra plants have not been widely cultivated and the cultivation method has not used the right technology, so it is necessary to examine the proper cultivation methods of Okra. This study aims to determine the EC value of the most optimal nutrient solution and the effect of the type of planting media that is best on the growth and yield of okra plants. The research was carried out in plastic houses located in Pondok, Karangbendo, Banguntapan, Bantul, Yogyakarta in May to August 2018. Experiments using polybag with a Complete Randomized Block Design (RAKL) Split Plot two factors were repeated 3 times. The first factor as the main plot is the EC value of nutrient solution (C1: EC value 1.5 mS / cm, C2: EC value 2 mS / cm, C3: EC value 2.5 mS / cm) and the second factor as sub plot is type planting media (M1: Husk charcoal, M2: Sand Malang, M3: Husk charcoal + Cocopeat (1:1). The results showed that there was no interaction between the treatment of giving various EC values of nutrient solution and type of planting media. The treatment of various EC values of nutrient solution and type of planting media significantly affected the parameters of plant height growth, leaf area, root volume, flowering age, stem diameter, parameters of total fruit yield per plant, fresh weight per fruit, total fruit weight per plant, fruit weight per Ha. The treatment of giving EC values of 2.0 mS / cm showed suitable results for the growth and yield of okra plants. The treatment of the type of husk charcoal growing media showed suitable results for the growth and yield of okra plants.Keywords: Okra Plant, Substrate Hydroponic, Planting Media, Solution EC Value

The objective of the experiment was to determine effects of Brassinosteroid (BRs) concentrations on growth, development and yield of Jasmine 85 rice cultivar under salinity conditions at panicle initiation stage. The experiment was laid out in a completely randomized design with three replications and consisted of two factors. The first factor comprised three salinity concentrations: 0‰ (control), 2‰ and 4‰ and the second factor had three concentrations of BRs: 0 ppm (control), 2 ppm and 4 ppm. The results showed that under non-saline conditions, the control rice plants sprayed with BRs at a concentration of 2 ppm had the highest values of root length (33.39 cm), leaf area (42.41 cm2), proportion of firm seeds (72.20%), weight of 1000 seeds (28.14 g) and yield (725.55 g/barrel). At the salinity level of 4‰, rice plants sprayed with BRs at a concentration of 2 ppm demonstrated the highest levels of APX and CAT enzymes. Briefly, rice plants grown under higher salinity levels had decreased growth and yield. Spraying BRs helped improve growth and yield parameters of rice under high salinity conditions.

Short term hardening before transplanting may enhance the defence mechanism of rice seedlings against any stress during their establishment and contribute d to enhanced growth and yield. Thus, this study was conducted involving one local inbred (Pajam), one popular high yielding (BRRI dhan53) and one hybrid (BRRI hybrid dhan4) rice variety. The experiment was laid out in randomized complete block design with two factors. Seedlings were transplanted directly to the main field as a control treatment and/or subjected to four different hardenings like seedlings storage in shade, open field under sunlight, float in water and cold air in refrigerator before transplantation. Hybrid variety out yielded both the local and inbred varieties due to their highest effective tillers, longer panicle length and 1000-grain weight. Pre-hardening of seedlings in open field under sunlight conditions enhanced the yield attributes and ultimate yield of rice compare to others. The best combination was pre-hardening seedlings in open field conditions with hybrid cultivar regarding to the yield attributes and final yields. It is suggested that hybrid variety and prehardening of seedlings before transplantation to the main field could be increase the rice yield productionsBangladesh Agron. J. 2016, 19(1): 87-97
