“…Regarding the number of panicle m -2 , the highest weight for produced the number of panicle m -2 when weeds were controlled by Saturn 2 l fed -1 + Inpul 20 g fed -1 and Saturn 2 l All the applied herbicide treatments showed great increases in rice grain yield as compared to the unweeded check plots in both seasons, because herbicides combination can control most of grassy, broadleaf and sedges weeds. Similar findings were reported by Tagour et al (2016) and Ghalwash et al (2019).…”

Two field experiments were conducted in Gemmeiza Agric. Res. Station, Gharbia Governorate, Egypt, during 2017 and 2018 summer seasons to study the effect of interaction between three planting methods (broadcasting, dibbling and transplanting) and eight weed control treatments (Saturn 50% at the rate of 1.0 L fed -1 , Saturn at rate of 2.0 L fed -1 , Saturn at rate of 1.0 L fed -1 + Basagran at rate of 1.5 l fed -1 , Saturn at rate of 2.0 l fed -1 + Basagran at rate of 1.5 L fed -1 , Saturn at rate of 1.0 l fed -1 + Inpul at rate of 20 g fed -1 , Saturn at rate of 2.0 l fed -1 + Inpul at rate of 20 g fed -1 , Hand weeding twice, and unweeded check) on weed species susceptibility to herbicides and rice productivity. A split plot design with four replicates was used , planting methods were assigned in the main plots and weed control treatments were distributed randomly in sub plots. The results revealed that transplanting and dibbling methods reduced the dry weight of total weeds at 65 days after planting (DAP) by (33.4 and 13.8%) and (33.6 and 12.5 %) in the two seasons, respectively, as compared with broadcasting method. The same trend occurred in the econd survey at 85 DAP. The transplanting and dibbling methods significantly increased rice yield by (16.32 and 6.75%) and (15.22 and 6.31%) in both seasons as compared with broadcasting method. Herbicidal combinations of (Saturn 2.0 Lfed -1 + Inpul 20 g fed - 1), (Saturn 2.0 Lfed -1 + Basagran 1.5 lfed -1 ), (Saturn 1.0 l fed -1 + Inpul 20 g fed -1 ), (Saturn 1.0 l fed -1 + Basagran 1.5 l fed -1 ) and hand weeding twice decreased dry weight of total weeds by 88.6, 86.6, 84.2, 82.4 and 79.0 %, in the first season at 65 DAP respectively as compared to the unweeded check, these results had the same trend in the second survey and second season. On the other hand, increased straw yield by (46.7, 46.5, 37.9, 37.8 and 29.0%) and grain yield by (51.0, 51.1, 40.2, 40.3, and 33.4 %), respectively, in the first season. The interaction between planting methods and weed control treatments were statistically significant on dry weight of total weeds. Transplanting and dibbling methods were superior by (27.6 and 11.4%) and (29.2 and 8.5%), respectively as compared with broadcasting method under unweeded check conditions in the two seasons. The best interaction between planting methods (transplanting and dibbling) with combination for weed control (Saturn 2.0 l fed -1 + Inpul 20 g fed -1 ), (Saturn 2.0 l fed -1 + Basagran 1.5 l fed -1 ) which decreased the dry weight of total weeds by 92.6 and 89.6 % at 65 DAP, as compared to unweeded check of broadcast, and increased the grains yield about 67.5 and 65.5 % as compared to unweeded check of broadcast method. The perivous results showed that weed stress was lower on rice yield under transplanting or dibbling methods than broadcasting method, due to the elimination of weed competition by these herbicide combinations . It is recommended to expand rice planting by broadcasting method and avoid the problem of well-trained labor and their ...

“…and (hand weeding twice) increased grain yield by 43.97, 59.1and 30.2 %, respectively as compared to the untreated check. Economic feasibility study of various weed management package results clearly can be grow rice under broadcasting method (Tagour et al, 2016).…”

Gulma adalah kendala biotik utama yang dapat mengakibatkan penurunan hasil gabah pada padi sawah. Teknik pengendalian secara kimia memberikan pengaruh yang cepat serta biaya yang lebih rendah sehingga lebih efektif. Penelitian ini bertujuan untuk mencari dosis herbisida campuran yang efektif dalam menekan pertumbuhan gulma sehingga meningkatkan pertumbuhan dan hasil tanaman padi sawah. Penelitian ini dilaksanakan pada bulan Agustus-Desember 2021 di Desa Ciluncat, Kecamatan Cangkuang, Kabupaten Bandung, Jawa Barat. Penelitian ini menggunakan Rancangan Acak Kelompok dengan 7 perlakuan dan 4 ulangan. Perlakuan terdiri dari; 5 dosis herbisida campuran Penoksulam 15 g/l + Pretilaklor 385 g/l (dengan dosis 1,00 l/ha, 1,50 l/ha, 2,00 l/ha, 2,50 l/ha, 3,00 l/ha), penyiangan manual, dan kontrol (tanpa penyiangan dan tanpa herbisida). Hasil penelitian menunjukkan bahwa herbisida campuran Penoksulam 15 g/l + Pretilaklor 385 g/l pada dosis 1,00 l/ha sampai dengan 3,00 l/ha efektif dalam menekan pertumbuhan gulma dominan Ludwigia octovalvis, Cyperus difformis, Fimbristylis miliacea, Ammania coccinea, Monochoria vaginalis, gulma lain, dan gulma total hingga 6 MSA serta tidak meracuni tanaman padi sawah. Seluruh dosis herbisida campuran menunjukkan pengaruh nyata terhadap tinggi tanaman pada 3 MSA, jumlah anakan pada 3 MSA dan 6 MSA, jumlah malai per rumpun, dan berat gabah kering giling sedangkan tinggi tanaman pada 6 MSA, jumlah bulir per malai, serta bobot 1000 butir tidak menunjukkan pengaruh yang nyata.
