Abstract
Although the productivity is very low, maize cultivation on Madura island still uses the local varieties. Considering this situation a field assessment was carried out in Larangan Slampar Village Tlanakan District Pamekasan Regency from May to August 2017. The study was aimed to determine the performance of several national hybrid maize varieties that especially released by the Indonesian Agency for Agricultural Research and Development (IAARD). The experiment was arranged in a randomized completely block design with three replications. The treatments were five superior varieties of the IAARD namely Bima 9, Bima 14, Bima 16, Bima 20, and HJ 21, and one local variety of Madura as a control. The result showed that new varieties tested especially Bima 9 and Bima 14 gave the best performance and significantly different to local variety in some agronomic parameters namely plant height, width and length of leaves and yield. Almost of all agronomic parameters had a positive correlation to the yield. The yield was increased up to 483.87% and the benefit up to 555,67 % than local variety. Based on this research and by the choosing of local farmers, both varieties were recommended as a specific location varieties in dry season planting time.

Abstract
The integration of rice and cow is one way to optimize the use of existing resources in farmers. This integration is mainly for farmers who have relatively narrow land (0.1 - 0.5 ha). In the bioindustry concept, the rice-cow farming system is primarily aimed at obtaining an ecological balance in one ecosystem because the agricultural system which does not take into account the principles of ecological balance is part of efforts to destroy natural resources and the environment. This paper will discuss the use of available resources in the location to integrated pest control (IPM) in the farming system of rice-cow in Lampung Province. These local resources can come from plants, microorganisms, animals etc. which together and integrated contribute to the application of IPM in rice cultivation. At paddy, Corine bacterium is often used to reduce infections from fungi and bacteria as in blas disease caused by Pyricularia sp. The use of local resources such as coryne bacterium frequency of 15 days can reduce blast disease approximately 45.82%, and crackle disease around 50.2%. The use of a combination of local resources such as corin, refugia and vegetable pesticides will be better able to suppress both pests and diseases on rice. The use of local resources will support the work of natural enemies on rice, and contributes to a sustainable agricultural system.

Abstract
Sorghum as a drought tolerant crop, its planting is directed to marginal dry land type agro-climate which is relatively hotter for the supply of alternative food for rice substitution. The food sorghum genotype was selected from a multilocation test of 15 accessions plus Numbu variety, local Lombok and local Flores, so that there were 18 accessions arranged according to the randomized block design with three replications as the main crop. Spacing of 75 cm x 20 cm (66,666 plants per ha), fertilized with 135 kg N, 45 kg P2O5 and 60 kg K2O per ha on the main crop. After the main crop has been harvested, relatively homogeneous shoots are kept as ratoon plants until harvest and are fertilized 1 time as much as 50% of the main crop fertilizing dose after the shoots begin to grow. The results showed that five sorghum genotypes in the ratoon cultivation system produced higher seeds than superior varieties of Numbu and were significantly higher than those of Flores and local Lombok. Sorghum genotypes that provide high profits from two seed harvests (main crop yields > 6 t / ha and sorghum rations > 5 t / ha) compared to three comparative varieties, especially Numbu, are genotypes No. 58-1 (Rp. 14,922,700); 86-1 (Rp. 13,954,200); 11-5 (Rp. 13,936,000); 113-1 (Rp. 13,905,000); and No. 103-1 (Rp. 13,006,800) while Numbu benefits Rp. 12,178,500 / ha. This is supported by higher genotype farming efficiency values, ranging from R/C of 2.36 - 2.53 and B/C of 1.36 - 1.53 and lower cost per kg ratio of Rp 790 - 846 / kg of temporary seeds Numbu value of R/C 2.26; B/C 1.26 and the cost/kg ratio of seeds is Rp 884.

This study was aim to know the performance and utilization of local sorghum in West Nusa Tenggara especially in Bima District. A collection of sorghum samples was performed on a population of sorghum farmers in both small and larger planting areas. Observations were made on the characteristics of plant and panicle. In addition, interviews were conducted on farmers using questionnaires to obtain data on harvested area, planting location, harvest time, and sorghum utilization. Qualitative data obtained were analyzed descriptively and presented in tables and figures, while quantitative data were analyzed using Annova test continued by BNJ/Tukey at 0.05 level of significant. There are six (6) local sorghum varieties whose appearance are very different from one another namely gando bura, gando keta, gando keta 2, latu kala, latu keta, and latu keta 2. Varieties had effect on plant height, diameter of stem, leaf size and panicle length. Apart from being distinguished by the color of the husk, they are also distinguished from the shape and presence of fur at the tip seed. Specifically gando bura variety has the ability producing until 12 tillers. Sorghum has been consumed by Bima community as a main food mixed with rice, as well as processed food such as dodol sorghum and sorghum porridge.
Citrus foot rot disease (Phytophthora spp.) control in Indonesia using good agricultural practices efforts green agroindustry
Authors: Dwiastuti Mutia Erti 
Published: June 2020

AbstractFoot Rot (Phytophthoraspp.) is an important disease in Indonesia and in the world. Around 35% of citrus plantations have been damaged by the complex of foot rot disease and Diplodia disease (Botryodiplodia theobromae), mainly in swamps and irrigated fields. The spread of the disease is fast, but the knowledge of citrus farmers is still limited, causing rapid death in production plants. This paper purpose is to provide an overview of the citrus root disease control from research studies supporting the efforts of Good Agricultural Practices in Indonesia. Usually farmers only rely on systemic pesticides to control disease, but it is not always successful. Control by means of healthy cultivation is highly recommended in supporting green agroindustry and saving nature. Integrated and rational control strategies, require knowledge of the ecology and epidemic of diseases ranging from seedlings to gardens. Propagule pathogens can survive in seeds, tree stumps, soil, even in alternative hosts. Therefore, to control the disease it must be directed not only to oranges but also to alternative hosts as well and to destroy pathogenic retention sites. The recommended integrated control strategy is to use disease-resistant plants, making sewers, garden sanitation, and optimal maintenance. This method is very effective and environmentally friendly.

AbstractThe types of pests that attack many soybean plants in South Sulawesi are armyworms, aphids, pod suckers and pod borer. This study aims to determine the level of pest attack and the use of insecticides at the farm level of soybeans. Inventory research on the intensity of major soybean attacks was carried out in 2016/2017 in many agroecosystems/vegetation spread across 3 districts, Wajo, Jeneponto, and Bulukumba Districts. The three districts are centers of soybean cultivation with diverse agroecosystems/vegetation. The results achieved showed that the intensity of the main soybean attack was highest in the monoculture vegetation (Wajo District), respectivelySpodoptera lituraarmyworm (45.65%), pod borer(Etienlla zinkenella)(31.26%), aphids (20.15% ), and pod suckers (26.13%). Whereas in the polyculture area of coconut + soybean plants (Bulukumba Regency), the rate of pest attacks were respectively: armyworm &S.litura(22.13%), pod borer,E. zinkenella(18.12%), aphis (10. 12%), and pod suckers (16.19%). In the polyculture area of palm + chilli + soybean (Jeneponto Regency), the rate of pest attacks were:S. lituraarmyworm pest (19.11%), pod borer (15.17%), aphids (14.28% ), and pod suckers (11.13%). The highest use of insecticides in monoculture agroecosystems (8.1 l ha−1per season) and the lowest in soybean + chilli + palm tree agroecosystems (1.5 l−1per season). Polyculture farming on soybeans will reduce the use of insecticides at the farm level, so as to create an environmentally friendly agricultural model compared to monoculture agroecosystem.

Published: June 2020

Abstract
Biodiversity is one measure of ecosystem balance, so that biodiversity is important to know the condition of the ecosystem in the fields. A high diversity index shows the high stability of the ecosystem because the food webs formed are more complex. The purpose of this study was to obtain information about the diversity of insects in the paddy ecosystem with ecological engineering and without ecological engineering. This research was conducted at the Experimental field of Tungro Disease Research Station, Lanrang Sidrap, South Sulawesi, Indonesia from June to August 2017 using the observation method by periodically observing each week starting at plants 2 weeks after planting. The design used a split-plot design consisting of 2 main plots, namely 1) Ecological Engineering Agroecosystem, using flowering plants (refugia) and pest control with andrometa which is a mixture of entomopathogenic fungus Metharizium anisopliae and bitter extract; 2) Conventional agroecosystems, without flowering plants and pest control using pesticides. The results show that the number of pests and natural enemies found in ecological engineering agroecosystem plots is higher than conventional plots. While the index value of pest diversity and natural enemies in both observation plots is classified as moderate. Therefore, the ecological engineering agroecosystem by planting refugia plants is needed to increase the number and types of arthropods of natural enemies.
