Penelitian bertujuan untuk mengetahui pengaruh ketinggian tempat dan sistem tanam terhadap kelimpahan gulma padi sawah pergolongan di kabupaten Garut dengan menggunakan metode survai yang dilakukan pada dua ketinggian (T) yaitu t1 dataran rendah dan t2 dataran tinggi pada dua sistem tanam (S) yaitu; s1 sistem tanam Sistem of Rice Intensification (S.R.I) dan s2 sistem tanam konvesional. masing- masing diulang 6 kali. data yang diperoleh kemudian dianalisis dengan mengunakan ANOVA dan jika terjadi pengaruh nyata dilakukan uji lanjut LSD pada taraf 5%. Hasil penelitian diketahui terjadi interaksi antara ketinggian tempat dan sistem tanam terhadap kelimpahan gulma padi sawah, pada kelimpahan spesies gulma golongan berdaun lebar, spesies gulma golongan berdaun sempit, populasi gulma berdaun sempit. Kombinasi dataran rendah dan sistem tanam konvensional (t1s2) nenunjukkan rata-rata spesies gulma tertingi, kombinasi dataran tinggi dan sistem tanam konvensional (t2s2) menunjukkan rata-rata golongan gulma berdaun sempit tertinggi dan kombinasi dataran rendah dan sistem tanam S.R.I (t1s1) menunjukkan rata-rata populasi golongan gulma berdaun sempit tertinggi. Kata Kunci : gulma, kelimpahan, ketinggian, padi sawah, sistem tanam,
ABSTRACT
This study aims to determine the effect of altitude and planting system on the abundance of paddy rice weeds in Garut district by using a survey method carried out at two altitudes (T), namely t1 lowland and t2 highland in two cropping systems (S), namely; s1 cropping System of Rice Intensification (S.R.I) and s2 conventional cropping system. each repeated 6 times. The data obtained were then analyzed using ANOVA and if there was a significant effect, the LSD continued test was carried out at the 5% level. The results showed that there was an interaction between altitude and planting system on the abundance of lowland rice weeds, the abundance of broadleaf weed species, narrow leaf weed species, and narrow leaf weed populations. The combination of lowland and conventional cropping systems (t1s2) shows the highest average weed species, the combination of upland and conventional cropping systems (t2s2) shows the average of the highest narrow-leaf weeds and the combination of lowland and SRI cropping systems (t1s1) shows average -the highest average population of narrow-leaved weeds.
