Abstract

Desa Sukarame memerupakan bagian dari Kecamatan Leles, Kabupaten Garut. Desa ini berada di dataran medium (697 mdpl) dan memiliki luas wilayah yaitu 374,3 ha, yang terdiri dari tanah sawah 92 Ha, tanah kering 224 Ha dan tanah perkebunan 5 Ha. Jumlah penduduk Desa Sukarame sebanyak 6.169 jiwa dan mayoritas adalah sebagai buruh tani. Petani di Desa Sukarame umumnya bertanam tanaman padi sawah dan tanaman jagung sebagai tanaman utama. Pola tanam yang biasa dilakukan di Desa Sukarame adalah Padi-padi-jagung. Sistim tanam tanaman jagung adalah secara konvensional yaitu persiapan tanah, pencangkulan tanah dua kali kemudian penanaman. Sistim penanaman ini memerlukan tenaga kerja dan upah yang tinggi, sehingga pendapatan petani jadi berkurang. Sistim penanaman pada tanaman padi sawah dan tanaman jagung di Desa Sukarame adalah secara konvensional yaitu masih menggunakan pupuk anorganik. Penggunaan pupuk organic atau kompos belum banyak digunakan para petani di Desa Sukarame, walaupun bahan pembuatan pupuk organic seperti limbah rumah tangga, limbah pertanian dan peternakan banyak tersedia di wilayah Desa Sukarame. Penggunaan pupuk organic atau kompos selain bisa menyuburkan tanah dalam jangka panjang juga bisa mengurangi biaya produksi. Pembuatan pupuk organik yang berasal dari limbah pertanian, rumah tangga dan kotoran ternak ini belum banyak dikenal di Desa Sukarame. Pelatiahan yang telah dilaksanakan telah memiliki dampak sebagai berikut: (1) Pengetahuan dan ketrampilan petani khususnya peserta kegiatan bertambah dengan adanya penyuluhan dan pelatihan pembuatan pupuk organic atau kompos yang baik dan benar. (2) Masyarakat sasaran bertambah pengetahuannya tentang pentingnya menjaga kesuburan tanah dengan mengurangi penggunaan pupuk kimia. (3) Masyarakat tani tanggap dan termotivasi untuk mengurangi penggunaan pupuk kimia dan mulai menggunakan pupuk kompos, karena penggunaan pupuk kompos dalam jangka Panjang bisa menyuburkan tanah.

Abstract

The transgenic corn variety, NK 603, which contains a gene called CP4 EPSPS (5-enolpyruvyl shikimate-3-phosphate synthase) which makes the corn plants tolerant to the glyphosate herbicide, on the other hand conventional corn varieties are sensitive to glyphosate. It was required to test the chlorosis and burn-down effect both in transgenic and conventional corn varieties due to glyphosate. The experiment was conducted to quantify the burn-down effects and chlorosis due to the application of herbicide glyphosate potassium 660 g L⁻¹ on two varieties of corn at the Agriculture Faculty Research Station of Padjadjaran University, West Java, Indonesia, from December 2015 to April 2016. The experiment was arranged in randomized block design with 20 treatments and each treatment replicated twice. At 15 days and 20 days after planting, five transgenic corn varieties (C 7 RR, 979 RR, 77 RR, 85 RR and 95 RR) and five conventional corn varieties (C 7, 979, 77, 85 and 95) were applied with herbicide glyphosate potassium 660 g L⁻¹ at a dose of 2 L ha⁻¹. The results showed that the herbicide was effective to control the weed in both transgenic and conventional corn varieties. The transgenic corn variety exhibited smaller percentages of chlorosis (0–20%) and no burn-down effect was observed following applications of glyphosate potassium 660 g L⁻¹. On the other hand, chlorosis and burn-down effects were found on all conventional corn varieties. The yield of transgenic corn varieties was higher than those of the conventional corn varieties.

Abstract

Glyphosate is a non-selective systemic herbicide that has been widely used to control weeds by local corn farmers in South Sulawesi and Lampung Provinces of Indonesia. However, some corn farmers in these two regions were considered that glyphosate herbicide at the standard field dose no longer effective against goosegrass (Eleusine indica). To confirms the level of its resistance to glyphosate, seeds of E. indica suspected to be glyphosate-resistant were collected from corn fields in Soppeng Regency-South Sulawesi and South Lampung Regency-Lampung (designated as GR-1 and GR-2 respectively), along with a known susceptible biotype from Sumedang Regency-West Java (GS) as a comparison. By using whole-plant pot assay method in a greenhouse at the Ciparanje. A range of seven glyphosate concentrations was applied to the seedlings at the Experimental Farm, representing 0, 0.25, 0.5, 1, 2, 4, and 8 x the standard field rate. Dose–response experiment showed that GR-1 and GR-2 biotypes has a low levels resistance to glyphosate (2.57 and 2.96 folds of each) compared to susceptible biotype (GS). Sequencing results confirmed the Pro-106-Ser mutation in the EPSPS genes of the resistant biotypes. This specific amino acid substitution is among the most frequently documented mechanisms of resistance in weed species. Therefore, the shared mutation in the GR-1 and GR-2 biotypes likely confers this resistance. These findings serve as an early warning for corn farmers to manage and prevent further spread of E. indica glyphosate-resistant biotypes.
