Abstract

Jack bean (Canavalia ensiformis), Indonesian local bean, has a high content of protein and great potential either for substituting or overcoming the shortage of imported soybean in tofu production. However, an appropriate coagulant in a proper amount is needed to make tofu with acceptable characteristics. This study set out to investigate the appropriate type and concentration of coagulant. The experiment was carried out by using GDL (glucono delta lactone) and nigari as coagulants with concentration levels of 0.25; 0.5; 0.75 and 1%. Some quality parameters such as yield, color, texture (hardness, cohesiveness, chewiness, springiness), and microscopic structure of tofu were observed. Consumer preference tests on aroma, color, taste, texture, and overall acceptability were directed to determine tofu with the best characteristics. The result showed nigari at concentration level 0.75% delivered the most preferred tofu for consumers.

Abstract

Differences in location and rhizosphere cause differences in species diversity and population of Arbuscular Mycorrhizal Fungi (AMF). In addition, not all AMF have the same morphological and physiological characteristics, therefore it is very important to know their identity. This study aims to determine the presence and number of spores as well as to determine the morphological characteristics of AMF originating from the rhizosphere of several horticultural crops in the agricultural land of Payakumbuh State Agricultural Polytechnic. The method used in this research is descriptive exploratory method by means of purposive sampling for soil sampling. While the stages of this research include: taking and collecting data in the field, determining the point of location for soil sampling, taking soil samples, analyzing soil properties in the laboratory, isolating AMF spores and identifying AMF spores morphologically. The conclusions of this study are 1) The population of AMF spores in horticultural land is high. The highest spore population was found in soil samples of the root area of shallot plants (556 spores per 10 g of soil), while the lowest number of spores was in soil samples of eggplant root areas (271 spores per 10 g of soil), 2) AMF exploration in several horticultural crops in the agricultural land of the Payakumbuh State Agricultural Polytechnic, based on morphological identification (shape, color and size), the AMF found consisted of three genera, namely Glomus sp, Gigaspora sp, and Scutelospora sp.

Abstract

Cotton is the largest industrial sector in Pakistan. However, due to bad traditional practices and use of high amount pesticides, the whole industry lost about 10-15% of cotton. For reasons of socioeconomic and environmental harm, the Better Cotton Initiative (BCI) launched "Better Cotton" in Pakistan. Better cotton production is a more environmentally friendly alternative to traditional cotton due to its efficient resource utilization and lower environmental externalities. CABI encourages farmers to implement better cotton production principles and criteria, use better cotton standard system and good agricultural practices (GAP), and provide participatory training for small, medium and large-sized farmers and farm workers in their "learning groups" and medium-sized farmers' fields. The aim of this short communication article is to put together a concise review of Better Cotton production. In this short communication we briefly present the history, importance, aim, distribution and principles of Better Cotton Initiative.

Abstract

Currently, basal stem rot disease incident in oil palm caused by the Ganoderma sp. increasing rapidly. Arbuscular mycorrhizal fungi (AMF) are one of the types of mycorrhizae that are useful for plants as they can increase plant growth and resistance to disease. Therefore, this study aimed to determine whether the application of AMF to oil palm seedlings was able to increase the growth and resistance of oil palm seedlings against Ganoderma sp. The study used a factorial treatment design (4x2) with 5 replications arranged according to a completely randomized block design. The first factor was the type of AMF, namely without AMF (m0), Glomus sp. (m1), Entrophospora sp. (m2), and a mixture of Glomus sp. with Entrophospora sp. (m3). The second factor was soil from the oil palm rhizosphere that was attacked by Ganoderma sp., namely sterilized soil (g0) and unsterilized soil (g1). The data obtained were analyzed using analysis of variance and the mean separation was tested using the Least Significant Difference test at the 5% level. The results showed that all AMF treatments (m1, m2, and m3) increased the growth of oil palm seedlings compared to controls. Ganoderma sp. present in the planting medium has not inhibited the growth of oil palm seedlings (both control and those applied with AMF) as there is no Ganoderma sp. infection in the roots of oil palm seedlings observed at the end of the study (5 months after planting)

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

Quicklime is a widely used industrial chemical and its characteristics may be affected by the limestone characteristics and calcination temperature. The present study investigated the quicklime characteristics obtained from limestone after calcination at different temperatures (800, 900, and 1000 ℃) from six geological-different mines in West Sumatera, Indonesia. X-ray fluorescence (XRF) analysis was performed to characterize the elemental compositions in limestone and quicklime. The stoichiometric evaluation was examined to compare the obtained carbon dioxide (CO2) from experimental and theoretical results during calcination. Based on elemental composition from XRF analysis, all the investigated limestones are very pure limestones, with impurities of less than 1%. The level of calcium oxide (CaO) after calcination at 1000℃ increased to more than 90% for all investigated limestone. The obtained CaO and CO2 mass after calcination at 1000℃ for 5 h were more than 70 and 60 grams, respectively. However, the experimental results on CaO and CO2 mass were 5–12% less than theoretical mass, reflecting the partial decomposition of calcium carbonate during the calcination process.

Abstract

In Nepal, underutilized crops are the crop species which have high potential for food, nutrition, dietary and culinary diversification but are less prioritized in formal research, education, extension and development. Analysis of the trend of production and trade helps to formulate and prioritize governing policies for the development of the underutilized crops in Nepal. Analyzing this need, This study aims to reveal the production and trade scenario of major underutilized crops of Nepal; mainly Finger millet, Buckwheat and Barley over the years. Secondary data collected from Food and Agriculture Organization Corporate Statistical Database (FAOSTAT), Ministry of Agriculture and Livestock Development (MoALD), Department of Customs and relevant articles were used for the study and to analyze the ongoing trend, simple linear regression model was used. Collected and analyzed data revealed that, production area of millet is decreasing. However, the production quantity is increasing mainly because of the increased productivity. Though the production is increasing, the import of millet is also high. Increased consumption of local liquor products made from millet followed by diversified food product consumption have seems to conduced the increased demand. The production area of buckwheat found steady over a decade, however, the production and productivity is increasing. The production area and productivity of barley is decreasing while the import of barley is increasing from 2013/14 with the sudden fall in 2019/20. The sudden decrease in import in 2019/20 was due to trade restriction due to Covid situation. But now the demand of these underutilized crops is increasing year after year, and this will continue in forthcoming years also, mainly because of raise in awareness about the health and nutritional benefits. To reduce the ballooning trade deficit of these crops in near future, along with productivity, effective area expansion policies and programs should be formulated and implemented from all three tiers of government.

Abstract

Forests, traditional gardens and green spaces play an important role in regulating the water flow of an area. Along with the high demand for land in Bali for agriculture and tourism, many forest areas have been converted into hotels and settlements. Forest conversion has caused many problems such as erosion, soil fertility decreased, flora fauna extinction, floods, drought, global warming and the disturbing watershed, especially rivers for springs. The purpose of this study is the development of watershed conservation in Bali based on traditional agroforestry. The method that used is vegetation analysis. Calculation of the erosion amount using the USLE formula. Sampling was done by ten plots. The results showed that traditional agroforestry vegetation consisted of vertical and horizontal structures. The characteristic of traditional agroforestry is that dominant plants are distributed irregularly, thus creating a miniature structure like a forest. The vertical structure consists of trees, horizontal structure filled with species of garden plants and agriculture. Trees have roots spread intensively in the soil and reduce nutrient leaching. Land cover by vegetation protects the soil and erosion. The agroforestry has a role as an act of soil and water conservation. Traditional agroforestry land cover has a relatively low C coefficient (0.05-0.25) compared to other lands. The level of erosion hazard is low and moderate. Average erosion value of 55.01 t.ha-1.yr-1. This indicates that traditional agroforestry makes the soil have a higher ability to absorb water, thereby reducing surface runoff. Likewise, organic material that improves the water content capacity. In addition, water quality can be improved through the humus filter function. During a long dry season, there is a drought due to low rainfall, but rivers and springs were able to supply water for the peoples daily needs. This condition occurs because of the tree retentions in traditional gardens. Conservation actions need to be taken, namely maintaining trees vegetation, increasing reforestation, bench terraces use, mounds and mulch use. This condition also places traditional agroforestry as a sustainable land management system.
