Abstract

Many ways can be done in an effort to increase the production of shallots, such as regulating the right dosage of fertilization, regulating the optimum spacing, proper irrigation, good pest, and disease control and choosing varieties that have high production potential. There are several varieties that are often cultivated by farmers in West Nusa Tenggara, namely Keta Monca varieties from Bima, Brebes varieties originating from Central Java, Super Filip varieties and Vietnamese varieties. Technological innovations by trying out several superior varieties of shallots also need to be socialized to the community by conducting community service activities in an effort to implement a culture system that is environmentally friendly, sustainable and can improve crop yields. This community service activity was carried out in Seteluk Village, Batulayar District, West Lombok Regency, which is a shallot producing area. The method used in carrying out community service is a training method that is continued with practical work in the field by conducting demonstrations and active participatory action research. To see the results of community service an evaluation was conducted which included: average plant height, tuber yield per plot, attendance and participation of participants in adopting the applied technology, and discussion during the extension. The results of the demonstration plot of mycorrhizal biofertilizer application on four shallot varieties showed that the Keta Monca variety originating from Bima gave the best growth and yield and was suitable for planting in the lowlands. The presence and participation of farmers during community service was very enthusiastic about the delivery of extension materials. The participants' understanding of the material provided was very good, as seen from the number of participants who asked questions and the relevance of the questions posed by the participants in accordance with the extension material delivered.

Abstract

The fate of glyphosate in soil and water is dependent on the properties of glyphosate and its envoronement. Behaviour of glyphosate in soil, sediment and water is strongly influenced the way by which it can be adsorbed by soils, sediments, and suspended material in water. The role of soil organic matter, clay mineral, and amorphous minerals on the adsorption of glyphosate depends primarily on the nature and properties of the soil itself and the properties of glyphosate. Environmental factors have some influence on sorption and degradation of glyphosate. Glyphosate is rapidly inactivated in soil, is in part due to adsorption. Some soil properties have been identified strongly influence adsorption of glyphosate, such as clay minerals, composition of cations in exchangeable site of clay and organic matter, unoccupied phosphate adsorption site, degree of humification, and soil pH. Adsorption limits the availability of glyposate for microbial degradation. The sorbed glyphosate is not directly available to microorganisms in soil. Evidence also suggests that not only a strongly sorbed compound such as paraquat but also weakly sorbed compounds such as flumetsulam and picloram can persist for long periods when they are sorbed by soil constituents. This suggests that the interaction between sorption and biodegradation should be considered in predicting the fate of pesticides in soils and sediments.
