Abstract

This study aims to determine the effect of humic acid and micro compound fertilizer on soil microbial populations and yields of Inpago10 varieties of upland rice in coastal areas. This research was conducted from August to December 2021 in Beringin Jaya village, Muara Bangkahulu District, and analysis of soil and plant samples at the Soil Science Laboratory, Faculty of Agriculture, University of Bengkulu. This study was prepared using a randomized complete block design (RCBD) with 2 factors.The first factor is the dose of humic acid which consists of 3 levels, namely 0 L ha-1 , 8 L ha-1, and 16 L ha-1. The second factor is a compound micro fertilizer consisting of 2 levels, namely 0 g ha-1 and 70 g ha-1. Each treatment was repeated 4 times, resulting in 24 experimental units. Observation variables include C-organic (%), respiration, total microbial population, pH KCl, pH H2O, plant height (cm), the number of grains per panicle, plant dry weight (g), root dry weight (g), and weight per plot (g plot-1). The Data were analyzed using variance analysis and extended with DMRT at the level of 5%. The results showed that the application of humic acid was able to stimulate the population of soil microorganisms by 38.91% and the addition of micro compound fertilizer was able to increase the yield of weight per plot by 26.69%.

Abstract

Sugarcane is the major crop of district Charsadda-Pakistan and weeds infestation is the most problematic factor responsible for low yield in sugarcane. For the purpose a field experiment was conducted to find out the important and most problematic weeds of Sugarcane crop using quadrate method in different sugarcane fields at DistrictCharsadda, Khyber Pakhtunkhwa, Pakistan. The data was collected during summer season,2021. Based on spatial data it is concluded that Cyperus rotundus L., Parthenium hysterophorus L., Trianthema portulacastrum L., Euphorbia helioscopia  L., Convolvulus arvensis  L., Brachianreptans (L.)., Amaranthus viridusL., Physalis minima  L., Dactydocteniumaegyptium(L)., Amaranthus spinosusL., Portulaca  oleracea  L.,CynodondactylonL. and  Solanum nigrum  L., were the most abundant weeds of the studied fields. The relative weed densities (%) and relative frequencies (%) of all these weeds were calculated to quantify their importance values in descending order of their percentages as following: P.hysterophorus, T.portulacasrum, C.rotundus,  E. helioscopia. C. arvensis, B.reptans, A.viridus, and S. nigrum. Similarly, the highest (35.1%) importance value recorded for C. rotundus and declared the most competitive weed of sugarcane at district Charsadda. The control of C. rotundus recommended for the farmers of the area for the outmost yield of sugarcane.

Abstract

Coal mining in Indonesia is generally carried out by open-pit mines so which impacts the decline of environmental quality degradation and damage to the soil’s physical properties. One of the steps taken by PT Bukit Asam Tbk to solve this problem is to carry out land reclamation by using eucalyptus plants. This study aims to of the revegetation age of eucalyptus plants on changes in the soil’s physical properties of post-coal mines. This research was carried out from October to December 2021 on post-coal mining land after the revegetation of eucalyptus plants for 3 years, 5 years, and 10 years in Pit Banko Barat, PT Bukit Asam Tbk. At the research location measurements and sampling were taken and followed by analysis at the Soil Science Laboratory, Bengkulu University. The data obtained were analyzed by descriptive statistics and normality test then continued analysis of variance and BNT test. The results showed that the age of eucalyptus plants has a significant effect and can improve soil density and root penetration at the age 5 and 10 years in post-coal mining land. The soil’s physical quality showed that soil bulk density, particle density, liquid limit, root penetration, groundwater level, as well as increased porosity and C-organic. It has the same texture that is clay and some changes in the blocky structure to be granular.

Abstract

The aims of this study were 1) to find optimum dose of bokashi applied for cabbage growth based on the improvement of the total soil aggregate stability, soil moisture content, soil pH, 2) to find soil tillage method for optimum growth of cabbage based on the improvement of the total soil aggregate stability, soil moisture content, soil pH, , and (3) to find interaction between dose of bokashi applied and soil tillage method for the optimum growth of cabbage. This research was conducted from March to June, 2020 in Muara Bangkahulu sub-district, Bengkulu City. The research location lies on ± 500 m above sea level with soil type of Ultisol. The research used Split plot design with 3 replications. The main plot was 3 soil tillage methods involved no tillage, minimum tillage (1 time hoe tillage), and intensive tillage (2 time hoe with 1 time rake), and the sub plot consist of 4 doses of bokashi involved 0 ton ha-1, 5 tons ha-1, (2,81 kg plot-1), 10 tons ha-1, (3,75 kg plot-1), and 15 tons ha-1 (5,62 kg plot-1). The research resulted there was interaction between the soil tillage method and the bokashi applied on the improvement on the total soil aggregate stability. An increasing dose of bokashi applied on all soil tillage treatments was followed by the increasing the total soil aggregate stability. Minimum- and intensive soil tillage methods gave better growth of cabbage in form of the plant height and the leaf number than no tillage to the cabbage growth. Bokashi applied with doses of 10 tons ha-1 and 15 tons ha-1 improved soil pH, soil moisture content, and the cabbage growth.

Abstract

Cultivation problems on marginal Ultisol involved low soil organic matter content, low water holding capacity and low soil aggregate stability. These constraints determined cabbage growth because of root crop development limited and plant nutrient uptake inhibited. Application of chicken manure could overcome the marginal constraints through improving soil aggregate stability and soil moisture content on the marginal Ultisol as well as the cabbage growth increased. The purpose of this study was to evaluate the soil aggregate stability and soil moisture in Ultisol as affected by the chicken manure applied and the cabbage growth improvement. This study was conducted from December to February, 2021 at Agriculture Station, Faculty of Agriculture, University of Bengkulu lying on ±100 m above sea level. The experiment design used was Completely Random Block Design (CRBD) with the chicken manure applied involved 5 doses; 7.5 tons ha-1, 15 tons ha-1, 22,5 tons ha-1, 30 tons ha-1, and without the manure as a control treatment. From the variance analysis (ANAVA) in the level of 5%, the chicken manure applied was significantly influence the improvement of soil aggregate stability and soil moisture content as well as the cabbage growth. With Duncan Multiple Range Test (DMRT), the dose of 7.5 tons ha-1 gave the highest value of the soil aggregate and soil moisture improvement. Furthermore, the chicken manure application of 7.5 tons ha-1 improved significantly the cabbage stem diameter at the age of 15 days, 30 days, and 45 DAP. The 7.5 tons ha-1 manure applied also gave significantly a number of leaves at the age of 15 days and 30 DAP. The height of plant was significantly influenced when the cabbage growth 15 DAP with 15 tons ha-1. In short, the chicken manure applied with 7.5 tons ha-1 gave the soil aggregate stability, the soil moisture, and cabbage growth improvement.
