Tanaman kopi seringkali dibudidayakan di areal hutan, dimana terdapat tanaman tahunan seperti pepohonan yang terus tumbuh sehingga menurunkan intensitas cahaya yang jatuh ke tanaman kopi. Hal ini menjadi masalah bagi pertumbuhan dan perkembangan tanaman kopi yang dinaungi pohon tersebut. Penelitian ini bertujuan untuk menguji fisiologis dan agronomis dua kultivar kopi dalam intensitas naungan yang berbeda untuk mendapatkan informasi kultivar kopi yang terbaik. Percobaan dilaksanakan dari bulan Maret hingga Juni 2020 di Kebun Percobaan Ciparanje, Fakultas Pertanian, Universitas Padjadjaran, Jatinangor, Sumedang, Jawa Barat. Percobaan menggunakan Rancangan Petak Terbagi (Split plot) dengan dua faktor dan diulang sebanyak tiga kali. Taraf dari main …

Tanaman raps (Brassica napus L.) adalah tanaman penghasil minyak utama di negara dengan iklim dingin seperti di Jerman. Minyak raps (Brassica napus L.) digunakan untuk bahan pangan, biodiesel, dan sebagai pakan ternak. Kandungan minyaknya bisa mencapai 33 – 48%. Tanaman minyak seperti kedelai (Glycine max), raps (Brassica napus L.), bunga matahari (Helianthus annuus) pada umumnya menyimpan kandungan minyaknya dalam suatu organela penyimpanan dikenal dengan ‘oil body’ yang mempunyai diameter antara 0,6 hingga 2,0 µm, tergantung dari spesies tanaman. Peningkatan kandungan minyak merupakan salah satu target pemuliaan di banyak tanaman minyak, termasuk di raps. Tulisan ini menceritakan tentang isolasi ‘oil body’ …

Jurnal Kultivasi
Keberadaan gulma pada pembibitan kelapa sawit dapat menurunkan kualitas bibit. Pengendalian gulma di pembibitan awal harus dilakukan secara dengan tangan (hand weeding), karena bibit dapat mati akibat aplikasi herbisida. Aplikasi bioherbisida saliara (Lantana camara) pada bibit kelapa sawit (Elaeis guineensis Jacq.) dapat menjadi alternatif pengendalian gulma yang ramah lingkungan dan mengurangi tenaga kerja. Penelitian ini dilaksanakan di Kebun Percobaan 1 Politeknik CWE, pada November 2019 sampai Februari 2020. Percobaan disusun dalam Rancangan Acak Kelompok, dengan perlakuan: kontrol (tanpa aplikasi bioherbisida), Ekstrak Lantana camara 1%, 2%, dan 3%. Setiap perlakuan diulangi sebanyak tiga kali. Hasil penelitian menunjukkan bahwa Bioherbisida Lantana camara …

Two challenges that the global wheat industry is facing are a lowering nitrogen-use efficiency (NUE) and an increase in the reporting of wheat-protein related health issues. Sulphur deficiencies in soil has also been reported as a global issue. The current study used large-scale field and glasshouse experiments to investigate the sulphur fertilization impacts on sulphur deficient soil. Here we show that sulphur addition increased NUE by more than 20% through regulating glutamine synthetase. Alleviating the soil sulphur deficiency highly significantly reduced the amount of gliadin proteins indicating that soil sulphur levels may be related to the biosynthesis of proteins involved …

Cover crops are considered an integral component of agroecosystems because of their positive impacts on biotic and abiotic indicators of soil health. At present, we know little about the impact of cover crop types and diversity on the organic carbon (OC) contents of different soil aggregate-size classes. In this study, we investigated the effect of cover plant diversity on OC contents of different soil aggregates, such as macro- (<2000–500 µm), meso- (<500–250 µm), and micro-aggregates (<250 µm). Our experiment included a total of 12 experimental treatments in triplicate; six different monoculture treatments such as chickling vetch (Vicia villosa), crimson clover (Trifolium incarnatum), hairy vetch (Vicia villosa), field peas (Pisum sativum), oilseed radish (Raphanus sativus), and mighty mustard (Brassica juncea), and their three- and six-species mixture treatments, including one unplanted control treatment. We performed this experiment usingdeep pots that contained soil collected from a corn-soybean rotation field. At vegetative maturity of cover plants (about 70 days), we took soil samples, and the soil aggregate-size classes were separated by the dry sieving. We hypothesized that cover crop type and diversity will improve OC contents of different soil aggregate-size classes. We found that cover plant species richness weakly positively increased OC contents of soil macro-aggregates (p = 0.056), whereas other aggregate-size classes did not respond to cover crop diversity gradient. Similarly, the OC contents of macroaggregates varied significantly (p = 0.013) under cover crop treatments, though neither monoculture nor mixture treatments showed significantly higher OC contents than the control treatment in this short-term experiment. Interestingly, the inclusion of hairy vetch and oilseed radish increased and decreased the OC contents of macro- and micro-aggregates, respectively. Moreover, we found a positive correlation between shoot biomass and OC contents of macroaggregates. Overall, our results suggest that species-rich rather than -poor communities may improve OC contents of soil macroaggregates, which constitute a major portion of soil systems, and are also considered as important indicators of soil functions.
