Rice yields under conventional techniques are very low without high doses of commercial fertilizer application, while intercropping with legumes can increase yields. This research aimed to examine the effect of relay-planting peanut between rice rows of different patterns on yield of red rice in aerobic irrigation systems, by conducting a field experiment designed according to Split Plot design with two treatment factors, i.e. intercropping as main plots (T0= without; T1= intercropping with peanuts), and rice row patterns as sub-plots (P1= normal or single-row; P2= double-row; P3= triple-row). In T1, one row of peanut was relay-planted (additive series) between single, double, or triple rows of red rice plants three weeks after seeding red rice on raised-beds. Results indicated that additive intercropping with peanut significantly increased clump size, dry straw weight, filled panicle number, panicle length, total biomass, filled grain number, grain yield per clump, and harvest index, and reduced percentage of unfilled grains of red rice , while patterns of rice rows only affected dry straw weight, percentage of panicle number, and weight of 100 grains. However, there were significant interactions between the treatment factors on dry straw weight and percentage of panicle number, which under single-row, they were low in monocropping but high and no differences between row patterns in intercropping system. Similarly, grain yield was lower in single or double row than triple row pattern under monocropping but significantly higher and no differences between row patterns under intercropping, indicating the highest benefits of intercropping under single row pattern.

Di lahan sawah, petani umumnya menanam tanaman palawija termasuk tanaman jagung pada musim kemarau setelah padi sawah, ketika ketersediaan air irigasi tidak cukup untuk tanam padi. Penelitian ini bertujuan untuk mengetahui pengaruh teknik budidaya padi antara sistem konvensional dan sistem irigasi aerobik pada bedeng tumpangsari dengan kacang tanah terhadap pertumbuhan dan komponen hasil tanaman jagung ketan varietas lokal Bima, yang ditugal langsung pasca padi tanpa olah tanah. Percobaan dilaksanakan di lahan sawah Desa Beleke, Kecamatan Gerung, Lombok Barat, dari bulan September sampai Desember 2018, yang ditata menurut Rancangan Split Plot dengan tiga blok (ulangan) dan dua faktor perlakuan. Faktor petak utama adalah teknik budidaya padi beras merah (T1= konvensional; T2= sistem aerobik tumpangsari dengan kacang tanah yang ditanam-sisip antar barisan padi), dan faktor anak petak adalah pola barisan padi beras merah (B1= barisan normal atau single row; B2= barisan kembar atau double row; B3= barisan triple row). Hasil penelitian menunjukkan bahwa teknik budidaya padi berpengaruh nyata terhadap pertumbuhan dan komponen hasil tanaman jagung ketan, yaitu lebih tinggi jika ditanam pasca padi sistem aerobik tumpangsari dengan kacang tanah dibandingkan dengan pasca padi kovensional. Pola barisan padi pada umumnya tidak berpengaruh terhadap komponen hasil tanaman jagung ketan, namun terdapat interaksi yang signifikan antara kedua faktor perlakuan penanaman padi beras merah terhadap panjang tongkol dan berat biji pipilan kering per tanaman jagung ketan pasca padi beras merah. Hasil biji jagung ketan tertinggi pada barisan double-row (183,2 g/tanaman) atau single-row (164,1 g/tanaman) jika ditugal langsung pasca padi sistem aerobik tumpangsari dengan kacang tanah, sedangkan jika pasca padi konvensional, hasil biji tertinggi pada pola barisan triple-row (58,4 g/tanaman).
