Abstract

Tithonia diversifolia is a weed that can be used as a source of organic material in situ to support organic agriculture in a sustainable manner. The purpose of this paper is to introduce techniques to prepare sources of in situ organic material with Tithonia diversifolia weed plants in a sustainable manner. Tithonia diversifolia weeds contain high N and K nutrients up to 4.5% and can be pruned every 2 months with a large amount of biomass that can be used as a source of organic material in the form of green fertilizer or compost with good quality and enough available throughout the growing season. The preparation technique is done in two ways, namely by cultivating aisle and cultivating a garden circle. The results showed that the provision of Tithonia diversifolia in the form of compost was able to reduce the amount of Urea and KCl fertilizer as much as 50% of its needs with corn production of 6.68 tons / ha and soybean production of 1.80 tons / ha. Tithonia diversifolia is easy to grow anywhere with poor land conditions even with a fairly good level of adaptation.

Abstract

Regosol has low fertility, especially carbon (C), nitrogen (N), phosphorus (P), potassium (K) and other macro elements, but it can be potential for agriculture cultivation. Addition of straw compost and tithonia granule (Kojeto granule) with clay binder can improve chemical soil fertility. This study aimed to determine the composition of the Kojeto granule with a clay binder and to define the interaction between type of Kojeto granule and dosage of compost granule in the chemical characteristics of Regosol. This research was conducted in a wirehouse and soil laboratory, Andalas University. The experiment used a completely randomized factorial design, with two factors and three replications. The first factor was the ratio between compost composition and clay binder 9:1 and 8:2. The second factor was 4 levels of granule compost doses (0; 7,5; 15; 22,5 t ha-1). The results showed that the best composition ratio between Kojeto and clay binder on chemical properties was 9:1. The type of Kojeto 8:2 and dosage (22 t ha-1) had an interaction on Ca-dd (3.75 me 100 g-1). The single effect on the type compost granule at type 9:1 was parameter C-org (2.23%), and single effect on increasing the dosage of granule compost at a dose of 15 t ha-1 was C-org (2.30%), N-tot (0.27%), P-available (14,30 ppm), pH (5,80), and K-dd (0.62 me 100 g-1). The optimal recommended dose is 15 t ha-1.

Abstract

Soil acidity is the dominant factor in the phosphate amount, distribution of nutrients in the aggregate is important to supporting nutrient requirement and cycling. Furthermore, Al-P and Fe-P or Ca-P bonds trapped in soil minerals, also physically protected from loss due to associate with aggregates. Thus, the factual limitation of phosphorus becomes a topic, including various aggregate fractions changes and their effect on the slope. Soil samples were taken from 36 years old plantations consisting of 45 points with two depths (0 - 20 cm and 20 - 40 cm) on a various slope, soil samples fractionated into several aggregate fractions, namely micro (<250 µm), meso (250-2000 µm) and macro-aggregates (2,000-5,000 µm). For chemical analysis, soil pH was measured by pH meter, aluminium with the volumetric method, and P-available with Bray method. Based on the analysis, it is known that the P content in the meso aggregate is higher than P content in the macro aggregate ± 0.055 g m-2 for 0 - 20 cm ± 2.136 g m-2 for 20-40 cm depth, and ± 1.058 g m-2 for slope of 0-8% at 0-20 cm depth. In total, phosphate in the tea plantation area is very low.

Abstract

This study aims to identify the problems and develop rice agribusiness in Mentawai Islands from upstream to downstream and formulate appropriate policy recommendations to be implemented. The research location determined by purposive namely in the village Makalo and Malakopa District of South Pagai, Sikakap subdistrict Taikako Village, Village Saumanganya District of North Pagai, Bosua Village and Village Beriulou District of South Sipora, Village Rogdog and Madobag District of South Siberut. Respondents in this study were 30 farmers. Respondents farmers selected by simple random sampling method. The results showed that the majority of rice paddies new openings in six districts consist of peatlands with a depth varying from 0.4- > 2.0 meter, fields new openings that have been implemented in the Mentawai Islands in general can not be expected to result in maximum productivity due to problems of land suitability diverse. Farmers also do not take action appropriate technical culture starting from land preparation, seed selection, weeding, fertilizing and water management. Behaviorally agriculture, farmers in Mentawai Islands is not a society that blends with the culture of rice fields, it is because basically their agricultural base is dry land agriculture with farming patterns. This will certainly give a great challenge and not easy for the cultivation of rice in the Mentawai Islands.

Abstract

The application of true shallot seed cultivation technology with the planting spacing and number of seedlings per planting hole is expected to increase the productivity of shallots in Indonesia. The research was carried out at KP Sukarami-AIAT West Sumatra from January to June 2021. The aim of the study was to obtain recommendations for the appropriate planting spacing and number of seedlings per planting hole in increasing the growth and yield of true shallot seed in West Sumatra. The study used a 2-factor factorial design in a randomized block with 3 replications. The first factor is the planting spacing (JT), which consists of 3 types, namely: JT1 (10 cm x 10 cm), JT2 (10 cm x 15 cm), and JT3 (15 cm x 15 cm). The second factor is the number of seedlings per planting hole (JB) which consists of 5 types, namely: JB1 (1 seedling), JB2 (2 seedlings), JB3 (3 seedlings), and JB4 (4 seedlings). The results showed that there was not significant interaction between the planting spacing and the number of seedlings per planting hole on the yields of true shallot seed. The highly significant interaction was only found in the growth components and yield components. The best planting spacing is 10 cm x 10 cm and 10 cm x 15 cm, while the best number of seedlings is 1-2 seedlings per planting hole. It is recommended to use a planting spacing of 10 cm x 10 cm or 10 cm x 15 cm with 1-2 seedlings per planting hole in true shallot seed in the highlands of West Sumatra.

Abstract

Organic carbon contributes to increasing soil productivity. In determining the soil fertility indicators, soil organic carbon mapping is required to provide information and demonstrate the distribution of organic carbon. In this study, remote sensing method testing was carried out by comparing data between observations in the field with rice productivity estimation data using Landsat 8 imagery. The observation was conducted on paddy fields with an area of about 4,800.86 ha in the volcanic region of Mount Talang. This research used a survey method with a grid system of 1,000 x 1,000 m intervals with a soil depth of 0-20 cm and 20-40 cm. The parameters of the soil observations carried out were bulk density, pH, and organic carbon. The results showed that Mount Talang volcanic rice fields had an estimated soil organic carbon stock of ±6,426.118 tons. A weak correlation was obtained between organic carbon and the estimated value of paddy rice productivity (r  =0.024). Hence organic carbon in the study area could not be estimated with the value of lowland rice productivity.
