The experiment was conducted in the Abi Al-Khaseeb orchard, Basrah, Iraq during the 2019 season, on date palm (Hillawi cv.). The effect of foliar nano-fertilizer on the response of the growth and fruit ripening rate was amid. Adding nano-fertilizer to the annual date palm fertilization program improved growth and increased production. A comparison of foliar NPK (1, 2 g L-1) as nano-fertilizer and traditional fertilizer, and combined, was applied. The results revealed that the treatment of foliar traditional and nano-fertilizers together increased the weight of fruit and bunches, water content, indoleacetic acid, and gibberellic acid relative to other treatments. Nano-fertilizers (1g L -1) led to an increase in fruit ripening rate, dry mass, and total soluble solids, activity of the enzymes peroxidase, and superoxide dismutase, and abscisic acid content. The leaflet protein expression shows that the appearance of protein bands 1 to 5 and 6 was up-regulated by control and traditional fertilizer. Whereas the protein bands 6 and 7 were down-controlled under nano-fertilizer. Hierarchical cluster analysis of proteins in the leaf in response to traditional and nano-fertilizer showed two distinct clusters. The use of nano-fertilizer individually leads to the acceleration of fruit ripening. while the production fruit that is increased using foliar nano-fertilizer with traditional fertilizer.

<p>Secondary metabolites from <em>Mikania micrantha</em> could be expected to control barnyardgrass (<em>Echinochloa crus-galli</em>) characteristics and have an effect on lowland rice. This research was aimed to screening of secondary metabolites in <em>M. micrantha</em> extract, obtaining the greater extract concentration in suppressing the barnyardgrass growth, and determine the impact on the lowland rice characteristics. This method used was Randomized Completely Block Design in non-factorial within the concentration rates of <em>M. micrantha</em> extract using ethanol 96% (0%; 20%; 40%; 60%; 80%; 100%, and herbicide 2,4-D dimethylamine at the dose of 1 l ha^-1 as a comparison). Lowland rice and barnyardgrass characteristics were analyzed using F-test and followed by DMRT at 5% with SPSS software. The result showed that <em>M. micrantha</em> had secondary metabolites include alkaloids, flavonoids, and tannins. The concentration at 20 to 100% significantly decreased the fresh- and dry-weight of barnyardgrass with the highest suppressing found in 60% concentration by 65.91% and 67.92%, respectively compared to un-sprayed. The concentrations at 20% and 60% were classified as inhibiting the growth biomass of barnyardgrass. The concentrations at 20%, 60%, and 80% can still encourage the tillers growth of lowland rice. An extract concentration of <em>M. micrantha</em> at 20% can be applied to inhibit the growth of barnyardgrass biomass and stimulate the lowland rice tillers.</p>

Pendekatan atau metode untuk mengevaluasi potensi sumber daya lahan merupakan cara evaluasi lahan. Nilai produksi yang diharapkan yang mungkin diperoleh, serta informasi dan/atau arah penggunaan lahan yang diperlukan, akan diberikan oleh hasil evaluasi lahan. Evaluasi karakteristik tingkat kesesuaian lahan pada kawasan dilakukan untuk menganalisis upaya perbaikan yang ditujukan untuk meningkatkan produktivitas dan menghasilkan peta kesesuaian lahan aktual dan kesesuaian lahan potensial komoditas unggulan di kecamatan tersebut. Penggunaan lahan di Kecamatan Kualuh Selatan perlu didukung dengan informasi kesesuaian lahan Metode survei yang digunakan Satuan lahan berdasarkan peta lahan, kemiringan lereng, elevasi, dan tutupan lahan Proses membandingkan (matching) adalah metode analisis. Hasil penelitian menunjukkan bahwa tingkat kesesuaian lahan untuk tanaman pisang Kondisi lahan aktual menjadi Potensial yang sesuai dibudidayakan di Kecamatan Kualuh Selatan untuk tanaman pisang adalah faktor pembatas ketersediaan hara (na), rejim suhu (tc), media perakaran (rc), retensi hara (nr) dan bahaya erosi (eh). Usaha perbaikan yang dapat dilakukan yaitu pembuatan drainase, pengapuran CaCO3, pemberian bahan organic, pembuatan teras atau menanam sejajar dengan kontur dan pemupukan. Rejim suhu tidak dapat dilakukan usaha perbaikan.

Penelitian bertujuan untuk mengevaluasi pertumbuhan dan hasil Kailan dalam beberapa kombinasi jenis dan dosis pemberian bokashi. Penelitian ini dilaksanakan di kebun percobaan Growth Centre LLDIKTI-1 dengan ketinggian tempat± 25 mdpl pada bulan Nopember 2017 hingga Januari 2018 dengan menggunakan rancangan acak kelompok non faktorial yang terdiri dari 16 taraf perlakuan. Masing-masing perlakuan adalah B0: kontrol, B1: 150 gram bokashi jerami/polibeg, B2: 200 gram bokashi jerami/polibeg, B3: 250 gram bokashi jerami/polibeg, B4: 150 gram bokashi kotoran sapi/polibeg, B5: 150 gram bokashi kotoran sapi + 150 gram bokashi jerami/polybag, B6: 150 gram bokashi kotoran sapi+200 gram bokashi jerami/polibeg, B7: 150 gram bokashi kotoran sapi+250 gram bokashi jerami/polibeg, B8:300 gram bokashi kotoran sapi/polibeg, B9: 300 gram bokashi kotoran sapi+150 gram bokashi jerami/polibeg, B10: 300 gram bokashi kotoran sapi +200 gram bokashi jerami/polibeg, B11: 300 gram bokashi kotoran sapi + 250 gram bokashi jerami/polibeg, B12: 450 gram bokashi kotoran sapi/polibeg, B13: 450 gram bokashi kotoran sapi+150 gram bokashi jerami 150/ polibeg, B14: 450 gram bokashi kotoran sapi+200 gram bokashi jerami/polibeg, B15: 450 gram bokashi kotoran sapi+250 gram bokashi jerami/polibeg. Parameter pengamatan meliputi tinggi tanaman, jumlah daun, jumlah klorofil, luas daun, diameter batang dan bobot basah tumbuhan. Hasil penelitian menunjukkan bahwa pemberian bokashi kotoran sapi dan bokashi jerami padi mempengaruhi pertumbuhan dan hasil Kailan. Kombinasi terbaik terdapat pada perlakuan B5 (150 gram bokashi kotoran sapi+150 gram bokashi jerami/polibeg) dengan bobot basah (hasil) Kailan tertinggi yaitu 34,91 gram/tanaman.
