Abstract

To increase shallot productivity, it is necessary to apply true shallot seed (TSS) cultivation technology. This study aimed to determine the suitable method of application and dosage manure in increasing the bulb yield of true shallot seed. The research was conducted at the Experimental Garden of Sukarami AIAT, West Sumatera (altitude 1000 m above sea level and soil type Andosol). The research arranged using a Split Plot Design in randomized blocks, each with 3 replications. Main plot treatment (A) is a application method of manure which consists of 2 types, namely: A1 (given in a spread) and A2 (given in the planting hole). While the treatment of subplots (B) was the dosage of cow manure consisting of 6 types, namely: B1 (0 t/ha), B2 (5 t/ha), B3 (10 t/ha), B4 (15 t/ha), B5 (20 t/ha) and B6 (25 t/ha).  The seeds of the Lokananta variety were six weeks after sowing, planted at a spacing of 10x10 cm, 1 seedling/planting hole, on a plot measuring 5x1 m. The results showed that there were highly significant interactions were only found in bulb weight per clump and bulb diameter. The highest dry bulb yield was obtained at a dosage of 15-25 t/ha of manure. In order to make farming activities more efficient, it is recommended to use 15 t/ha of cow manure with the application method by spreading or in planting holes in the cultivation of true shallot seed in West Sumatera.

Abstract

Edamame has been known as a vegetable soybean that is highly nutritious and has become popular in Indonesia. As for other crops, soybean cannot avoid the presence of weedy plants in the field. The study reported here aimed at determining the effect of tillage on weed and the growth and yield of soybean for edamame production. A randomized completely block design (RCBD) with three repetitions was used for the three tillage systems (zero, reduced, and conventional tillage). Data of soybean growth and yield component were collected and analysed with analysis of variance and mean separation of DNMRT at 5% level. Results show that most growth and yield parameter components (plant height, number of primary branches, number of leaves, number of pods per plant, pod weight per plant, number of seeds per plant, and yield) were highest in favor of reduced tillage system. The highest yield of edamame soybean (13.50 ton ha-1) was observed in the treatment group of reduced tillage and the effect was similar to that of conventional tillage (13.29 ton ha-1). Reduced and conventional tillage resulted in the emergence of new weed species such as Digitaria sanguinalis and Synedrella nodiflora with the total SDR value for all treatment groups of 54.38% and 37.74%, respectively. In contrast, the application of herbicide glyphosate prior to land cultivation has completely controlled Napier grass (Pennisetum purpureum Schumach.) and rough Mexican clover (Richardia scabra L.).

Abstract

One of the limiting conditions for shallot plants to grow optimally is dry land conditions. Indigenous AMF application is one way to overcome this condition. This study aimed to determine the effect of indigenous AMF application on the morpho-physiological characters of two shallot varieties which are sensitive and tolerant to drought stress conditions. The study was carried out for 6 months on a wirehouse and laboratory scale. The Experiment used a completely randomized design with two factors. The first factor was varieties of shallots, i.e. Brebes (Sensitive) and Kuning (Tolerant) varieties of shallots. The second factor was the application of indigenous AMF which consisted of 5 levels i.e. Glomus sp1, Glomus sp2, Glomus sp3, a mixed those three isolates and control treatment (without application of AMF). The morpho-physiological observation parameters included header dry weight, root weight, and leaf proline content. From the observations, it can be concluded that under stressed conditions, the leaf proline content of the sensitive variety accumulated higher in the header than the tolerant variety, because the tolerant variety was better able to produce higher root and header weights when adapting than the sensitive. AMF inoculation did not show significant differences with the treatment without AMF inoculation on leaf proline. However, there was a tendency that inoculation of a mix of AMF isolates (Glomus sp1+Glomus sp2+ Glomus sp3) decrease the proline content in the leaves, both in sensitive and tolerant varieties so that plants are more resistant to drought stress.

Abstract

Dry gambier extract obtained from gambier plants contains tannins at relatively low levels. Tannins can be obtained by extracting dry gambier using water to achieve high yields within a relatively short processing time. This study aims to analyze the interaction between extraction time and microwave power in the tannin extraction process from gambier using the microwave-assisted extraction (MAE) method to maximize tannin yield.  The research method employed was a factorial design (AxB). Factor A was extraction time, consisting of five treatments (1; 2; 3; 4; and 5 minutes) and factor B was microwave power, consisting of five variations (180W; 300W; 450W; 600W and 850W). The results showed that the gambier extraction process using MAE demonstrated an interaction between extraction time and microwave power on the yield produced, but not on the tannin content. The most optimal temperature and power that can be used is 4 minutes at 600W microwave power with a yield of 44.66%. The treatment of temperature and microwave power in the gambier extraction process showed a significant interaction with the extract yield.
