Alfisol merupakan jenis tanah dengan kesuburan rendah, namun memiliki potensi untuk perluasan lahan bagi budidaya tanaman kedelai edamame. Aplikasi biochar dan vermikompos digunakan untuk memperbaiki nutrisi tanah dan mensuplai unsur hara pada tanah Alfisol. Penelitian bertujuan untuk mengetahui pengaruh aplikasi biochar dan vermikompos terhadap serapan nitrogen dan fosfor, serta hasil tanaman kedelai edamame (Glycine max (L.) Merrill) pada tanah Alfisol. Penelitian dilaksanakan pada bulan Agustus sampai Desember 2019 di kebun percobaan dan Laboratorium Agronomi dan Hortikultura, Fakultas Pertanian, Universitas Jenderal Soedirman. Penelitian menggunakan rancangan faktorial terdiri dari 2 faktor. Faktor I adalah aplikasi biochar, terdiri dari empat taraf yaitu B0: tanpa biochar, B1: 10 t/ha, B2: 20 t/ha, B3: 30 t/ha. Faktor II adalah aplikasi vermikompos, terdiri dari 3 taraf yaitu V0: tanpa vermikompos, V1: 10 t/ha, V2: 20 t/ha. Variabel yang diamati adalah sifat kimia tanah awal, kadar N dan P tersedia, laju pertumbuhan tanaman (LPT), laju asimilasi bersih (LAB), bobot polong segar per tanaman, jumlah polong per tanaman, serta analisis kadar N dan P jaringan tanaman. Hasil penelitian menunjukkan bahwa dosis biochar hingga 30 t/ha tidak meningkatkan serapan nitrogen, fosfor, dan hasil tanaman, sedangkan vermikompos hingga 20 t/ha meningkatkan kadar P jaringan, P tersedia, dan hasil tanaman, tetapi tidak meningkatkan kadar N jaringan, N tersedia, LPT, dan LAB. Hasil tertinggi diperoleh pada aplikasi biochar 30 t/ha dan 20 t/ha vermikompos. Tidak terdapat interaksi antara vermikompos dengan biochar terhadap pertumbuhan dan hasil tanaman, sehingga dapat diaplikasikan secara secara tunggal.

This study that was carried out in paddy fields on Paguyangan Highway in Paguyangan Village, Paguyangan District, Brebes Regency, was aimed to find out the effect of the road incline position, the distance between road and rice field toward the lead content and rice productivity. The study used a survey method namely purposive random sampling with two factors. The first factor was the incline position consisting of three slope levels, i.e. the beginning of the ramp (T1) with an altitude of 300 m above sea level (m asl), and a slope of 3.4º, the mid ramps (T2) with an altitude of 315 m asl and slope of 15.84º, and the end of the ramp (T3) with an altitude of 330 m asl and a slope of 8.7º. The second factor was the distance of sampling points from road i.e. 15 m (J1), 35 m (J2) and 55 m (J3). The measured variables were lead contents in rice and soil, as well as, the yield of rice. The results showed that the difference in incline position and distance between roads toward plants did not significantly affect lead content in rice, lead content the soil, and rice productivity on paddy fields around Paguyangan Highway, Paguyangan Village, Brebes Regency, although the lead contents in rice and in the soils were above the specified threshold.

Peningkatan produksi padi lahan kering dapat dilakukan dengan sistem tumpang sari dan pemanfaatan asap cair tempurung kelapa. Penelitian ini bertujuan untuk mengetahui pengaruh tumpangsari padi gogo-rumput dengan aplikasi asap cair tempurung kelapa terhadap karakter pertumbuhan, fisiologis, dan hasil padi gogo serta tingkat serangan hama dan patogen pada kondisi kekeringan. Penelitian menggunakan rancangan petak petak terbagi dengan tiga ulangan. Petak utama terdiri atas varietas padi gogo; Situ Bagendit, Inpago Unsoed 1 dan Situ Patenggang. Anak petak merupakan konsentrasi asap cair tempurung kelapa yaitu tanpa aplikasi, konsentrasi 1:100 dan konsentrasi 1:200. Anak-anak petak terdiri atas tanpa rumput, rumput gajah, sereh dan rumput gajah+sereh. Variabel yang diamati meliputi tinggi tanaman, jumlah dan luas daun, jumlah anakan, kandungan prolin, kadar klorofil a dan b, jumlah gabah isi, bobot gabah petak efektif, bobot gabah ha-1, indeks panen, serta intensitas serangan hama dan patogen. Hasil menunjukkan bahwa padi gogo yang ditanam pada kondisi kekeringan dengan penanaman rumput dan aplikasi asap cair tempurung kelapa belum mampu menghasilkan produksi yang optimal. Tumpangsari padi gogo-sereh lebih memberikan dampak terhadap karakter pertumbuhan dan hasil padi gogo dibandingkan dengan aplikasi asap cair tempurung kelapa. Secara umum, hasil padi gogo < 1 t ha-1, namun varietas Situ Patenggang menunjukan hasil lebih baik dibandingkan varietas lainnya. Intensitas serangan walang sangit lebih rendah pada sistem tumpangsari padi gogo varietas Situ Patenggang-sereh. ABSTRACTRice production in the upland can be increased by multiple cropping system and coconut shell wood vinegar application. The objectives of this study was to know the effects of intercropped rice–grass with application of coconut shell wood vinegar on characters of growth, physiological, and yield of upland rice as well as intensity of pest and disease under drought condition. Split split plot design with main plot of upland rice varieties i.e. Situ Bagendit, Inpago Unsoed 1 and Situ Patenggang, sub plot consist of coconut shell wood vinegar concentration i.e. 0, 1:100 and 1:200, sub sub-plot of rice–grass intercropped i.e. no grass, Pennisetum purpureum, lemongrass and Pennisetum purpureum+lemongrass were tested with three replications. Observed variables were plant height, leaf number, leaf area, number of tillers, contents of proline, chlorophyll a and b, weight of grain in effective plot, weight of grain ha-1, harvest index and intensity of pest and disease. The results showed that rice-grass intercropped and application of coconut shell wood vinegar in drought condition has not been able to produce the optimal production. Under drought condition, intercropped rice-grass had significantly impact on the character of growth and yield of the upland rice. Generally, all upland rice varieties gained low yield (<1 t ha-1), but Situ Patenggang variety showed higher yield than other varieties and low intensity of brownhopper attack as well as in rice-lemongrass intercropped.
