Abstract

In coal mine reclamation activities, topsoil is generally used as the top layer on the reclamation land surface and the primary material in the growing medium for reclamation plant seeds due to its abundant availability. Topsoil generally has a low fertility rate because the soil layers between horizons have been mixed. Improvement of topsoil quality can be performed by adding organic fertilizers. This study aimed to identify the effect of organic fertilizers, liquid complementary fertilizers (LCF), and their interactions on selected soil's chemical properties from the topsoil used as a seed growing medium. This study used a factorial completely randomized design (CRD) with two factors, consisting of organic fertilizer factors (guano phosphate, Subur Ijo, vermicompost) and LCF factors (IMO, liquid smoke, Vermiwash). The results showed that the independent treatment of organic fertilizers and LCF had a very significant effect on pH. The independent treatment of organic fertilizers had a very significant effect on organic C and Total K. Meanwhile, the interaction between the two treatments had a very significant effect on the Total N and Total P of the growing media. The addition of organic fertilizers and LCF can improve topsoil quality to be used as a medium for growing media.

Abstract

This research aimed to determine the response of growth and yield of cauliflower on giving bokashi chicken manure on peat soils. The research was conducted at Landasan Ulin Tengah Village, Liang Anggang Sub-district, Banjarbaru District. The implementation time is 5 months from July – November 2019. This research used a Completely Randomized Design (CRD) with single factor. The treatment factors were dosage of the bokashi chicken manure (B) with five levels of treatment (i.e  b0 = 0; b1 = 5; b2 = 10; b3 = 15; b4 = 20 t ha-1). Each treatment was repeated four times so that there were 20 units of trial. The variables observed are plant heigth, the number of leaves, flowering, fresh weight of plant and yield weight. The results showed that the treatment of bokashi chicken manure very significant affect the plant height parameters 20, 30, and 40 days, the number of leaves aged 30 and 40 days, flowering, fresh weight of plant and yield weight

Abstract

This research aimed to determine the effect and best dosage of rice hull ash on peat soils to growth and yieId of pakcoy. The research was conducted in September 2019 – November 2019 at the ExperimentaI Garden, AgricuIture FacuIty of Lambung Mangkurat University, Banjarbaru. This research used a CompIeteIy Randоmized Design (CRD), single factor. The treatment factors were dosage of the rice hull ash (A) with seven types of treatment, namely a0=0,a1=2,a2=4,a3=6,a4=8,a5=10,a6=12 (tons ha-1). Each treatment was repeated four times so that there were 28 units of trial. Parameters is observed the number of leaves, plant height, root canopy ratio, total fresh weight of plant, fresh weight of sale, and yield of pakcoy. The resuIts showed that the treatment of rice hull ash not significant affect the pIant height, number of Ieaves, root canopy ratio, totaI fresh weight of pIant, fresh weight of sale, root canopy ratio and yield of pakcoy

Abstract

This research was carried out from December to May 2018, at Greenhouse of Supervision and Certification of  Food Crops and Horticulture Banjarbaru. The objective of the study was to examine the effect of organic fertilizer type and dosage and to know the best dosage of each type of organic fertilizer on the physiological characteristics of shallots on ultisol soil. The experimental method is designed based on a two-factor nested design with Completely Randomized Compact Design (RAL) design. The first factor is the type of organic fertilizer (J) consisting of two levels namely cow dung (j1) and chicken manure (j2), the second factor is the organic fertilizer dosage nested in the organic fertilizer consisting of four levels of 10 t ha-1 (d1); 20 t ha-1 (d2); 30 t ha-1 (d3) and 40 t ha-1 (d4). Treatment was repeated 4 times, each experimental unit consisting of  3 polybags.  Observation variables were leaf N content, leaf chlorophyll content, the water content of bulbs and volatile oil content on bulbs. The results showed that the type and quantity of organic manure of cow dung and chicken manure had no significant effect on all observed variables. Limiting factors such as low light intensity are suspected to cause the type treatment and organic fertilizer dosage does not affect all observed variables. Light intensity and humidity during cultivation are incompatible with the requirements of shallots grow is also seen in the long period of vegetative shallots plant which is a manifestation of the plant's response to environmental conditions.
