Abstract

Gulma merupakan salah satu kendala utama dalam produksi padi sawah. Gulma menurunkan kualitas dan kuantitas hasil tanaman padi sawah sehingga gulma harus dikendalikan. Penelitian ini bertujuan untuk mengetahui efektivitas herbisida berbahan aktif etil pirazosulfuron 20% untuk mengendalikan gulma padi sawah. Percobaan dilaksanakan di SPLPP Fakultas Pertanian Universitas Padjadjaran Ciparay, Kecamatan Baleendah, Kabupaten Bandung, Jawa Barat pada bulan November 2018 sampai Maret 2019. Percobaan menggunakan Rancangan Acak Kelompok satu faktor dengan tujuh perlakuan dan empat ulangan. Percobaan terdiri atas lima perlakuan herbisida berbahan aktif etil pirazosulfuron 20% dengsan dosis 60; 80; 100; dan 120 g ha-1 , pembanding berupa herbisida formulasi lama dengan bahan aktif yang sama (80 g ha-1 ), pengendalian gulma manual dan tanpa pengendalian gulma. Hasil menunjukkan aplikasi herbisida berbahan aktif etil pirazosulfuron 20% dengan dosis 80 g ha-1 mampu menekan pertumbuhan gulmagulma Ludwigia octovalis, Marsilea crenata, Monochoria vaginali, Sphenoclea zeylanica, gulma teki Cyperus iria, gulma spesies lain dan gulma total, serta tidak menimbulkan fitotoksisitas terhadap tanaman padi.

Abstract

The rice cultivation systems commonly used by farmers are the transplanted (called ‘Tapin’) and the direct-seeded (called ‘Tabela’) system. The Tabela system has many advantages over the Tapin system but has a weakness: the increase in weed population due to water conditions during transplantation. Therefore, weed management is necessary to increase rice yields. One way to control weeds is by applying herbicides. Using a single active ingredient herbicide continuously increases the chances for weeds to develop resistance against these active ingredients. Therefore, mixing herbicides with different active ingredients can be an alternative to improve weed management. This study aims to determine the effect of weed control and cropping systems to suppress weeds and provide the highest growth and rice yield. The research was conducted at the Agricultural Training and Development Research Center (Sanggar Penelitian Latihan dan Pengembangan Pertanian [SPLPP]) of the Faculty of Agriculture, Universitas Padjadjaran, Ciparay, Bandung Regency. This research was designed as a separate plot design with ten treatments and three replications with the main plot of cropping system and subplots of weed control. Weed management treatments consisted of bensulfuron-methyl 12% and bispyribac-sodium 18%; penoxsulam 15 g/L and pretilachlor 385 g/L; cyhalofop-butyl 100 g/L; manual weeding; and untreated control. Results that showed significant differences were tested using Duncan's test (DMRT) with α = 5%. Results showed that the Tabela system combined with bensulfuron-methyl 12% and bispyribac-sodium 18% suppressed weed growth and provided good growth and rice yield.

Abstract

Weed control is essential for ensuring the diversity of weeds on agricultural land. A study was conducted in rice fields in Subang and Cianjur districts, where 24 fields were observed to have varying weed management approaches. The research employed descriptive methods, including surveys to identify weed types and destructive methods to analyze weed seed banks at different depths. The descriptive methods included surveys to identify weed types and destructive methods to analyze weed seed banks at different depths. Each district contained twelve rice fields that reflected diverse environmental conditions and weed control techniques, yet shared a similar age range of 1-5 weeks. The study examined the weed vegetation, community coefficients, weed diversity, weed dominance, and variations in seed banks at various depths. The results indicated that fields without herbicide-based weed control had a higher number of weed species than those using herbicides. Herbicide use effectively decreased weed populations, subsequently altering the seed bank composition. The dominant weeds in herbicide-treated fields were Cynodon dactylon, Pistia stratiotes, and Ludwigia adscendens, whereas Ludwigia adscendens, Cynodon dactylon, and Pistia stratiotes were dominant in fields without herbicides.
