“…Based on the above, it is believed that ecological indicators such as edaphic fauna of these locations may be affecting the production response of the crops. Edaphic fauna is already known to act on organic matter decomposition, nutrient cycling, litter fragmentation and gallery opening, performing numerous ecosystem functions under different soil management systems Bender and Van Der Heijden, 2015;Choudhary et al, 2018;Pompeo et al, 2017), as well as unquestionable usefulness as indicators, usually easy to collect in the field and identify Choudhary et al, 2018;Favero et al, 2011).…”

This study aimed to evaluate the relationship of edaphic fauna under a no-tillage system with different levels of soybean productivity [High (NTH), Medium (NTM) and Low (NTL)] in the west of Santa Catarina (Brazil), identifying which chemical and physical variables most affect them, and the best indicators that can be used. Native forest (NF) areas were used as a reference. A total of 207 samples of soil fauna were collected by soil monolith and pitfall trap methods over two years of evaluation in four municipalities. Based on edaphic fauna data, Shannon-Wiener (H'), Pielou (J), Dominance (D), Margalef and Fisher Alpha (α) indices were generated, in addition to the average richness and abundance. Data from NTs were submitted to analysis of variance and compared by Tukey's test (p > 0.05). The NF was used as a reference and compared with the agriculture system by Dunnett test (p > 0.05), and regressions between soybean productivity and diversity indices. The H', Margalef, α indices, and average richness for soil fauna sampled by soil monoliths followed the productivity gradient NTH > NTM > NTL, showing a positive correlation with the increase of soybean productivity. NTH has a diversity index similar to that of NF. Soybean productivity is affected by the richness and diversity of edaphic fauna, but abundance was not sensitive in predicting treatments under no-tillage; Fisher's alpha index was more sensitive in treatment separation with soil monoliths. The environmental variables aluminum, organic matter, phosphorus, potassium and penetration resistance affect the fauna edaphic.

“…Biological soil processes are enhanced and maintained through the use of multifunctional cover crops and a higher degree of crop diversification (Séguy et al, 2006;Palm et al, 2014;Rabenarivo et al, 2014). The cover crops grown in between crop cycles provide a continuous flow of fresh organic matter increasing soil organic C and N concentrations (Hok et al, 2015;Sá et al, 2015;Patra et al, 2019) while they also enhance soil biodiversity (Lienhard et al, 2013a, b;Choudhary et al, 2018;Jiang et al, 2018). The effects of DMC on the abundance and diversity of soil microbial communities' benefit, in turn the plant's development, and thus yield (Hungria et al, 2009;Palm et al, 2014;Lienhard et al, 2014).…”

Rice production in Southeast Asia is significantly affected by root-parasitic nematodes (RPN). The Green Revolution has encouraged new agricultural practices (e.g. intensive monoculture, high yielding rice variety) to respond to the high rice demand; however, these methods have promoted the spread of these pests. The recent banning of chemical nematicides resulted in a need for alternative sustainable control strategies. In the present study, we assessed the effects of a direct-seeding mulch-based cropping system (DMC) vs conventional plough-based tillages (CT) on soil properties, rice yield and RPN communities during a two-year trial in Cambodia. Our results show that on average the population densities of RPN were significantly higher in DMC than in CT. Molecular identification revealed only two RPN species associated with roots: Meloidogyne graminicola, not previously reported from Cambodia, was predominant and was present throughout the plant's development, whereas Hirschmanniella mucronata was only found at the tillering and milky stages. We conclude that DMC had a significant positive impact on rice yield, despite higher RPN short-term pressure. In order to increase the efficiency of such cropping systems, further studies and an evaluation of the long-term relationships between DMC, the nature of cover crops used, the soil biota including RPN, and rice yield should be conducted.

“…ISSN: 2278-3075, Volume-9 Issue-3S, January 2020 seed dryland agriculture commodities are entirely decreased. Dryland agriculture production decline caused by many things such as the presence of invasive plants or plant pests, soil fertility, crop rotation, cropping, maintenance, quality seeds, fertilizer, and land area [22][23][24]. Based on the results of Fuel (2004) existence of invasive plants or invasive plants became one of the factors causing the decline in agricultural production.…”

The existence of invasive alien species (IAS) in an ecosystem has become a global issue that continues to be discussed. Invasive plants led to the dominance of the crop in the fulfillment of competition for nutrients, water, light, and pollinated by pollinators. In Indonesia there are 27 IAS that is very dangerous and threatens the stability of the ecosystem. The introduction of IAS in Indonesia generally lowers production reached 20%, 1 individual IAS in the area of 0.1 m2 can reduce 57% of agricultural production. This aims to determine the introduction of IAS and its impact on agricultural. The method used is the analysis of vegetation, a literature review of national and international journals and complemented by interviews was conducted in June-October 2018 in Pacitan, East Java. Based on the research known biodiversity in the study site was (2.99) and Evenness medium (e '= 0.41) with the third-highest family Compositae (IVIs = 53.1), Poaceae (IVIs = 41.16), and Amaranthaceae (IVIs = 23.97). Cyperaceae and Compositae is the most dominant and is found throughout the agricultural types in the sites. Compositae is dominating (IVIs = 53.1). Alternanthera sessilis (IVIs = 23.97), Cyanthillium cinereum (IVIs = 1.45), and Ecinochloa colona (IVIs = 12.33). Based on the concept of IAS disturbance caused interference in terms of the type, intensity, spatial reach, frequency, and other factors are interspecific. According to the concept of disturbance the solution is control the growth and spread of IAS to save the ecosystem and agriculture sustainability.
