<p><strong>Abstrak.</strong> Biochar merupakan material baru yang diteliti secara intensif dalam waktu sepuluh tahun terakhir di berbagai penjuru dunia. Hal ini dipicu oleh fakta bahwa tanah-tanah Terra Preta di wilayah Amazon, Amerika Selatan, dikenal sangat subur karena mengandung arang yang dibentuk dari pembakaran minim oksigen (pirolisis) ribuan tahun yang lalu. Dalam kondisi kemajuan teknologi seperti sekarang ini para peneliti mencoba untuk meniru dalam memperoleh material serupa yang kemudian dikenal secara luas dengan istilah biochar dan menguji manfaatnya terutama untuk perbaikan kondisi tanah agar menghasilkan pertumbuhan dan produksi tanaman yang lebih baik, sekaligus mampu menjadi penghambat lepasnya karbon ke atmosfir (carbon sequestering). Sebagai sebuah topik riset yang baru tentu saja dapat dipahami bahwa hal tersebut menimbulkan pro- dan kontra, khususnya yang menyangkut manfaat positif secara luas. Pihak yang pro mendasarkannya pada banyak bukti tentang manfaat aplikasi biochar terhadap pertumbuhan dan produksi tanaman seperti halnya juga terhadap sifat-sifat tanah. Sebaliknya yang kontra menekankan terbatasnya data yang tersedia sejauh ini dan adanya ketidak-konsistenan hasil yang dilaporkan. Ulasan berikut ini mencoba untuk melihat dari dua sudut tersebut untuk memberikan gambaran yang sebenarnya bagi para calon peminat riset dan/atau pengguna biochar untuk kepentingan perbaikan kesehatan dan produktivitas tanah. Pada akhir diskusi disampaikan perlunya persyaratan mutu biochar untuk memperoleh hasil yang dapat diperbandingkan.</p><p><em><strong>Abstract.</strong> Biochar is a new material researched intensively within the last ten years in various parts of the world. This is fuelled by the fact that the lands of Terra Preta in the Amazon region of South America is known to be very fertile because it contains charcoal that was formed from the minimum oxygen combustion (pyrolysis) at times thousands of years ago. Under the conditions of technological advances like nowadays, researchers tried to replicate it in obtaining similar material which was then widely known by the term biochar and test its usefulness mainly to improved soil conditions in order to generate growth and better crop production and the same time capable of being a barrier to the release of carbon into the atmosphere (carbon sequestering). As a new research topic, it is understandable that it raises pros and cons, especially on its benefits. The pro-side emphasized on the proven beneficial application of biochar to improve growth and yield of crops as well as on soil properties. Others, rised the controversy focused on the limited data reported and somewhat inconsistency on the results. The following review is trying to look at it from the two angles to give the real picture for the prospective applicants of biochar such as researchers and users of biochar for the benefit of improving health and productivity of the soil. At the end of the discussion it is given the necessity for quality standard of biochar to obtain comparable results.</em></p><p> </p>

Okra or Lady’s finger, botanically known as Abelmoschus esculentus (L.) Moench, is a tropical and sub-tropical indigenous vegetable crop commonly grown for its fibrous, slimy, and nutritious fruits and consumed by all classes of population. It has also several medicinal and economic values. Despite its many uses and potential value, its importance is under estimated, under-utilized, and considered a minor crop and little attention was paid to its improvement. The study was conducted to evaluate the effects of different planting densities and mulching materials on the growth and yield of okra grown in slightly sloping area in the marginal uplands in Sta. Rita, Samar, Philippines. A split-plot experiment was set up with planting density as main plot and the different mulching materials as the sub-plot which were: unmulched or bare soil, rice straw, rice hull, hagonoy and plastic mulch. Planting density did not significantly affect the growth and yield of okra. Regardless ofthe mulching materials used, mulched plants were taller and yielded higher compared to unmulched plants. Moreover, the use of plastic mulch resulted to the highest total fruit yield. The results indicate the potential of mulching in increasing yield and thus profitability of okra production under marginal upland conditions.

And Chemical Properties

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.

Investigating the effect of urea and nano-nitrogen fertigation and foliar application of nano B and Mo on growth and yield of potato Solanum tuberosum L. [Rivera-A]. The study was conducted in a private farm located in the Al-Taleah area - Babylon governorate. The experiment consisted of (12) treatments consisting of separated fertigation of nano nitrogen (25% N) and urea (46% N), single treatments of leaf spraying of nano Mo (5%), Nano B (9%), nano-binary combinations (Mo+B) and (U+ Nano Mo), (U+Nano B), Nano (N+Mo), Nano (N+B), and tricombination treatments of (U+Mo+B), Nano (N+Mo+B) additional to the control treatment. Randomize Complete Block Design (RCBD) and one way simple experiment with three replicates. Fertilizers were applied at levels of 40 liters h-1 of Nano-N fertilizer (25% N) and 300 kg h-1 urea fertilizer (46% N). They were sprayed early in the morning after (40) days after planting four times. Two weeks is the period between an application and another according to the recommendation of (1) kg  h-1 nano-fertilizer of (B) and (500) g h-1 of  Mo. Fertilizers were injected and sprayed at (10, 20, 30 and 40)% of the total amount of the fertilizer were applied as the first, second, third and fourth applications, respectively. Some growth traits were tested including the chlorophyll content in the leaves, the total dry vegetative yild, the soft tubers yield, and the biological yield, proteins and ascorbic acid yield compared to the control (spray water only). The results of the Duncan test showed a significant increase in most of the studied traits of nano-tricombination (N+Mo+B) in the fresh tubers yield,  dry vegetative yield  , the biological yield, starch yield ,the total protein and ascorbic yield (37.53, 1.799, 8.138,4.152 , 481.3and 653.8 meg ha-1) respectively .compare to control (21.58 , 0.890, 4.463  ,2.323 , 366.1 and 215.5 meg ha-1) respectively.
