Mojosari Village, Puger Sub-district, is the largest watermelon center in Jember Regency. In 2017, the total harvested area reached 900 Ha and productivity reached 290.72 kW / Ha. The problem that often arises in watermelon cultivation is the attack of plant pests. Pests that often attack watermelons include caterpillars, whitefly, fruit flies, and thrips. Pest control that is often used by farmers is sprayed with chemical pesticides. The spraying of chemical pesticides began to be complained about by farmers because they were not able to control pests, this was probably because the pests were already resistant to pesticides. The decline in watermelon quality is also caused by soil conditions that have begun to decrease in nutrient content, due to the use of excessive chemical fertilizers. Farmers become dependent on chemical pesticides and chemical fertilizers in watermelon cultivation. Therefore, it is necessary to educate farmers to reduce the use of excessive chemical pesticides and fertilizers. One alternative is to use environmentally friendly biological control agents. The result of this activity is that farmers can reproduce biological agents, namely the fungus Metarhizium anisopliae, Beauveria bassiana, Trichoderma, entomopathogenic nematodes, and make organic fertilizers. Farmers can produce biological agents and apply them to watermelon fields. The resulting watermelon is more durable to store and does not rot easily after harvest.

Chemical fertilizers are important inputs in agricultural production. They not only increase crop yield but also bring many negative effects, such as agricultural non-point source pollution. Therefore, a scientific understanding of the regional differences in chemical fertilizer application and its environmental risks is of significance to promote China’s agricultural development. In this study, we analyzed the spatiotemporal pattern of chemical fertilizer application intensity (CFAI) in China since 2000, evaluated the environmental risks of provincial CFAI, and investigated the internal mechanism behind them. The results showed that the total amount and intensity of chemical fertilizer application in China from 2000 to 2019 presented a trend of increasing first and then decreasing. In 2000 and 2019, provincial CFAI in eastern China was generally higher than that in central and western China, and the environmental risks of provincial CFAI were spatially characterized by “high in the north and low in the south”. Factors such as poor soil conditions, unreasonable farming structure and backward fertilization methods are the main reasons for the continuous increase in the total amount and intensity of chemical fertilizer application, while the construction of ecological civilization and the transformation of society and economy are the main reasons for their decline. Finally, measures such as targeted fertilization, adjusting the use structure of chemical fertilizers, improving fertilization methods and replacing chemical fertilizers with organic fertilizers are proposed to promote the quantity reduction and efficiency increase of chemical fertilizer application in China.

The Ministry of Agriculture through the Agricultural Quarantine Agency (2019) stated that Robusta coffee has contributed 41% of the country's foreign exchange, with an average export frequency of 102 times per month, and will continue to increase. In connection with the growth in export volume of robusta coffee, coffee farmers need additional substances for the soil in the form of nutrients to be able to meet the soil nutrient needs for coffee from planting to harvest. Organic fertilizer in liquid form is one type of fertilizer that can be an option, in addition to facilitating nutrient absorption. This study aims to determine the response of various liquid organic fertilizers at certain concentrations to the vegetative growth of robusta coffee. The content of C-organic and total Nitogen in the soil which has been given the addition of gamal liquid organic fertilizer and tofu wastewater with the addition of citronella can provide a very significant difference in the vegetative growth of robusta coffee plants at the age of 60 HSP at plant height, and 90 HSP in diameter. stem and number of leaves (strands). Based on the results of laboratory tests carried out, it was also known that the macro and micro nutrient content in the soil with the addition of poc of tofu wastewater which was given citronella had a good content compared to the control and soil conditions with the addition of gamal liquid organic fertilizer.

Mite Mortality

There is an urgent need to develop biological control methods against the eriophyoid mite, Phyllocoptes gracilis, which causes significant losses in organic raspberry production in Europe. The use of entomopathogenic fungi (EF) is a sustainable alternative to conventional chemical pesticides, reducing the risks of pesticide resistance and other negative environmental impacts of agriculture. The objective of this study was to assess the pathogenicity of three strains of EF, two of Beauveria bassiana and one of Metarhizium anisopliae, on P. gracilis under laboratory conditions. Fungal spore suspensions (1 × 107 spores per mL) were sprayed on detached leaves infested with P. gracilis. Treated mites were kept under controlled conditions (25 ± 3 °C, 72 ± 10% relative humidity and photoperiod of 16:8 (light/dark)) and mite mortality was assessed three, five and seven days after inoculation. At all three measurement points (days after inoculation), the mortality of P. gracilis was highest for B. bassiana strain BB 1.1 and M. anisopliae strain MA 10.1. Our data demonstrate that EFs are promising candidates for the development of biological control agents against P. gracilis in raspberry crops.

15N Abundance

Natural nitrogen isotope abundance (δ15N) has been suggested as a potential indicator for discriminating organic vegetables from their conventional counterparts. However, little is known about the δ15N characteristic of cauliflower (Brassica oleracea L. var. botrytis) under organic production and how the application of chemical fertilizers could affect this characteristic. In this study, δ15N characteristics of cauliflower (including the intra-plant δ15N characteristic) and soil under different fertilization treatments were investigated under field conditions. Five treatments were laid out: control, chemical fertilizers (F4M0), organic fertilizer (F0M4), and chemical fertilizer in combination with organic fertilizer at the ratio of 3:1 (F3M1) and 1:3 (F1M3). Results showed that plant δ15N was positively correlated with fertilizer δ15N and plant root/flower was more sensitive to changes of fertilizer δ15N and soil δ15N than leaf/stem. Distribution of δ15N in different plant parts (especially in flower and leaf) was significantly changed when organic fertilizers were partially or totally substituted by chemical fertilizers, suggesting a comparison of flower δ15N and leaf δ15N might be applicable for the organic identification of marketed cauliflowers. Our results provide fundamental data for the soil- and fertilizer-specific crop δ15N database and indicate that the intra-plant δ15N characteristic could be helpful for organic cauliflower identification.

Fertilization is an action in plant care. Fertilization provides additional nutrients for the soil. Fertilization has a large influence on plant growth and production. Fertilization consists of organic and inorganic fertilizers. Both of these fertilizers must be balanced so that the nutrient content can be maintained properly. The use of fertilizers an organic fertilizer that is widely used, but the use of chemical fertilizers on an ongoing basis will reduce the level of soil fertility. This must be balanced with organic fertilizer. One of the organic fertilizer is guano fertilizer. This fertilizer is fertilizer made from animal waste, namely bats. This fertilizer has a very good content including nitrogen, phosphorus, and potassium. Knowledgethis fertilizer will still be low, so that an introduction and practice about guano fertilizer is needed. Therefore a community service activity was carried out on the development of the manufacture of guano fertilizer. Guano fertilizer development is carried out in the form of granules (granules). The targets of this service are vocational students who are related to agriculture. Vocational students are selected as the young generation to know about organic fertilizers and are able to contribute to the implementation of the agricultural industry. Community service activities were carried out with a presentation of the theory and practice of making guano fertilizer. As a result of this activity, students learned about organic fertilizer, namely guano fertilizer and its contents, nutrient content in the soil, balance in maintaining nutrient content in the soil, the practice of making guano fertilizer, and the creation of granule form from guano fertilizer.

The Tropics

As a consequence of global warming, rainfall is expected to increase in several regions around the world. This, together with poor soil drainage, will result in waterlogged soil conditions. <em>Brachiaria</em> grasses are widely sown in the tropics and, these grasses confront seasonal waterlogged conditions. Several studies have indicated that an increase in nutrient availability could reduce the negative impact of waterlogging. Therefore, an outdoor study was conducted to evaluate the responses of two <em>Brachiaria</em> sp. grasses with contrasting tolerances to waterlogging, <em>B. ruziziensis </em>(sensitive) and <em>B. humidicola</em> (tolerant), with two soil fertility levels. The genotypes were grown with two different soil fertilization levels (high and low) and under well-drained or waterlogged soil conditions for 15 days. The biomass production, chlorophyll content, photosynthetic efficiency, and macro- (N, P, K, Ca, Mg and S) and micronutrient (Fe, Mn, Cu, Zn and B) contents in the shoot tissue were determined. Significant differences in the nutrient content of the genotypes and treatments were found. An increase of redoximorphic elements (Fe and Mn) in the soil solution occurred with the waterlogging. The greater tolerance of <em>B. humidicola</em> to waterlogged conditions might be due to an efficient root system that is able to acquire nutrients (N, P, K) and potentially exclude phytotoxic elements (Fe and Mn) under waterlogged conditions.  A high nutrient availability in the waterlogged soils did not result in an improved tolerance for <em>B. ruziziensis</em>. The greater growth impairment seen in the <em>B. ruziziensis</em> with high soil fertility and waterlogging (as opposed to low soil fertility and waterlogging) was possibly due to an increased concentration of redoximorphic elements under these conditions.
