Abstract

Dalam upaya meningkatkan kualitas sifat fisik, kimia, biologi tanah serta peningkatan produktivitas tanaman, sebaiknya dipilih bahan pembenah dari bahan yang sulit terdekomposisi agar dapat bertahan lama dalam tanah. Salah satu bahan yang memenuhi sifat tersebut adalah biochar, yaitu padatan kaya kandungan karbon yang merupakan hasil konversi dari biomas melalui proses phirolisis. Biochar memiliki keunggulan lebih resisten terhadap pelapukan di banding dengan bahan organik hasil dekomposisi, sehingga mampu memulihkan lahan-lahan pertanian yang terdegradasi. Tujuan dilakukan penulisan ini yaitu untuk mengetahui sifat dan karakteristik biochar, pengaruh biochar terhadap kualitas tanah dan produktivitas tanaman kedelai di lahan kering. Penulisan artikel ini dilakukan metode deskriptif, dimana teknik pengambilan data (literatur) didapatkan melalui buku, artikel, ataupun jurnal ilmiah dari penelitian-penelitian sebelumnya. Teknik pengumpulan data dilakukan dengan mengidentifikasi wacana, artikel, makalah, internet dan buku-buku, atau informasi lainnya yang sekiranya berhubungan dengan tujuan topik ini.

Abstract

The yield of tomato plants in dryland areas has been suboptimal due to environmental constraints such as poor soil health and high sunlight intensity. Appropriate agronomic modifications are necessary to improve crop yields while maintaining soil health. This study investigated the impact of various agronomic modification treatments on the growth and yield of tomato plants in dryland regions. The experiment was conducted in Gumantar Village, North Lombok Regency, during the dry season from June to August 2023. The agronomic modifications included a seaweed biochar treatment at a rate of 10 tons per hectare and 45% shading, with a control group that had no modifications. Three treatments were tested on two varieties of tomato plants: hybrid and local superior. The treatments were organized with four replications in a randomized complete block design with split plots, where agronomic modifications served as the main plots and the tomato varieties as the subplots. The results indicated that the interaction of agronomic modifications and plant varieties impacted the growth of tomato plants and various environmental factors. The hybrid variety under shading treatment exhibited the best growth. Additionally, this hybrid variety produced 59.6% more fruit than the local superior variety, yielding an average of 66 fruits and weighing 3.00 kg per plant. This study suggests that incorporating agronomic modifications, such as biochar treatment and selecting the appropriate variety, can enhance tomato yields in dryland areas.
