Abstract

One of the main problems in rice cultivation is the difficulty of controlling bondol bird (Lonchura punctulata) pest attacks. Bird pest is one of the main enemies of farmers that can reduce crop production. Increasing bird populations cause crop yields to decline. So that one way that can be used in repelling bird pests is by giving pesticides from garlic extract. Allicin is a compound that gives garlic its distinctive smell which repels bird pests. This study aims to determine the effect of the provision of plant-based pesticides from garlic extract in repelling rice-eating bird pests. This research was conducted in Tonasa Village, Takalar District, South Sulawesi, Indonesia. Research implementation methods include the manufacture and testing of pesticides liquid extracts of garlic and application in the field by spraying, this spraying is carried out in the morning, afternoon, and evening before making the observations. Observation parameters use the method of comparing initial observations and final observations observed in the morning, afternoon and evening (comparison method) by conducting initial data collection (without using pesticides) and final data collection (after spraying pesticides), the average number of groups of birds that attack 1 Ha of rice fields. The results obtained on average indicate quite a lot of attacks in a day, especially in the morning. After the use of the automatic repellent method the attacks of bondol bird groups tend to decrease where in the morning ratio of 20 to 33 decreases to 5 to 13 attacks, while the ratio of daytime 8 to 15 decreases to 3 to 7 attacks and the ratio of the evening 19 to 33 decreases to 6 to 12 bird group attacks. So that the administration of garlic extract pesticides is effective in reducing bird pest attacks.

Abstract

Pengembangan tanaman jagung toleran N rendah memerlukan seleksi genotipe pada kondisi pemupukan N rendah. Penelitian ini bertujuan untuk mengidentifikasi genotipe jagung hibrida (Zea mays L.) pada kondisi cekaman nitrogen rendah. Penelitian dilaksanakan di Kebun Percobaan Balai Penelitian Tanaman Serealia, Kecamatan Bajeng, Kabupaten Gowa, Provinsi Sulawesi Selatan, berlangsung dari Agustus hingga November 2019. Penelitian ini disusun dalam Rancangan Petak Terpisah dengan petak utama adalah dosis nitrogen (0 kg N/ha, 100 kg N/ha, 200 kg N/ha) sedangkan anak petak adalah genotipe jagung hibrida yang terdiri dari 5 genotipe dan 3 varietas pembanding (Nasa 29, Bisi 18, dan Jakarin 1). Hasil penelitian menunjukkan bahwa terdapat 3 genotipe yang toleran terhadap cekaman nitrogen rendah khususnya pada perlakuan dosis nitrogen 100 kg N/ha yaitu genotipe AVLN 122-2 × AVLN 124-9 (g1), AVLN 122-2 × AVLN 100-1 (g2), dan AVLN 118-7 × AVLN 124-9 (g3).
