<p>Bawang merah termasuk sayuran bumbu yang dibutuhkan oleh masyarakat dan harganya bersifat fluktuatif sehingga diperlukan kecukupan produksi untuk mendukung kestabilan harga. Kecukupan produksi dapat tercapai melalui pemanfaatan lahan marjinal seperti Ultisol yang masih luas dan perbaikan teknik budidaya, di antaranya melalui aplikasi pupuk Mikotricho. Tujuan penelitian adalah mengkaji pupuk Mikotricho dengan pengurangan dosis N-P-K terhadap pertumbuhan dan hasil bawang merah. Penelitian berupa percobaan lapang di lahan Ultisol menggunakan Rancangan Acak Kelompok Lengkap faktorial dengan tiga ulangan. Faktor pertama, dosis pupuk Mikotricho, yaitu 10 g, 30 g, dan 50 g/tanaman, faktor kedua, pengurangan dosis N-P-K berupa Urea, SP-36, KCl, dan ZA, yaitu 0, 25%, dan 50% dari rekomendasi. Hasil penelitian menunjukkan, aplikasi pupuk Mikotricho meningkatkan jumlah daun (11,4%) dan bobot tanaman segar (49,1%) bawang merah secara linier positif dengan dosis terbaik 50 g/tanaman. Hasil umbi/rumpun dan per petak efektif (0,64 m2) dosis pupuk Mikotricho, 10 g, 30 g, dan 50 g/tanaman tidak berbeda. Pengurangan dosis N-P-K dari rekomendasi berpengaruh terhadap jumlah anakan dan bobot segar tanaman bawang merah dengan efek linier negatif, namun pengurangan 25% dosis N-P-K dapat dipilih. Pengaruh interaksi pupuk Mikotricho dengan pengurangan dosis N-P-K terjadi pada kehijauan daun dan luas daun. Pemberian pupuk Mikotricho dosis 10 g hingga 30 g/tanaman dengan pengurangan dosis N-P-K 25% hingga 50% dari rekomendasi meningkatkan kehijauan daun dan luas daun bawang merah. Implikasi dari penelitian ini adalah diperlukan sosialisasi pemanfaatan pupuk Mikotricho pada budidaya tanaman bawang merah atau tanaman sayuran lain untuk mengurangi pemakaian pupuk sintetik dan perlu dukungan industri pembuatan pupuk Mikotricho.</p><p><strong>Keywords</strong></p><p>Mikoriza; <em>Trichoderma</em>; N-P-K; Bawang merah; Lahan marginal</p><p><strong>Abstract</strong></p><p>Shallots are a spice vegetable needed by the community.

`Jupiter' and `Verdel' bell pepper (Capsicum annuum L.) transplants set to the depth of cotyledon leaves or to the first true leaf yielded more fruit than transplants set to the top of the rootball. Increased yields and early stand establishment criteria (number of leaves, leaf area, plant weight, and plant height) suggest that planting pepper transplants deeper than is now common is commercially beneficial in Florida. Deeper plantings may place pepper roots in a cooler environment and reduce fluctuations in soil temperature. Moderated soil temperature, in conjunction with earlier fertilizer and water acquisition, may give deeper-planted pepper plants a competitive edge in growth.

Aims: This study aimed to optimize the levels of gibberellic acid (GA3) and plant spacing on growth and yield of lettuce. Study Design: The experiment was laid out in Randomized Complete Block Design with three replications. Place and Duration of Study: Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka-1207, from November 2013 to January 2014. Methodology: The experiment consisted of two factors. Factor A- two levels of gibberellic acid (GA3,) application, viz. G1= 25 ppm and G2= 50 ppm in relation to a control G0 and factor B- four plant spacing viz. S1=15cm x 15cm, S2=20 cm x 20 cm, S3=25 cm x 25 cm and S4=30 cm x 30 cm. GA3 was applied twice as a foliar application by hand sprayer at 20 and 30 days after sowing. First, second and final harvesting was done at 25, 35 and 45 days after sowing respectively. Results: The growth and yield characters of lettuce showed significant variation for different levels of GA3 and plant spacing. Among GA3 levels, 25 ppm GA3 produced the maximum number of leaves (15.6), leaf area (283.9 cm2), fresh weight (91.6 g plant-1), dry weight (11.8 g plant-1), fresh yield (1794 g plot-1) and gross yield (12 t ha-1) at final harvesting compared to control where GA3 was not used. Under plant spacing, highest plant height (17.5 cm), leaf area (281.1 cm2), fresh weight (99.1 g plant-1) and dry weight (12.1 g plant-1) was revealed from wider spacing 30 cm x 30 cm followed by optimum spacing 25cm x 25cm. Meanwhile, closure spacing 15 cm x 15 cm showed maximum fresh yield (1710 g plant-1) and gross yield (15.5 t ha-1) due to higher plant density at final harvesting. Besides, lower chlorophyll content (0.43%) and the highest number of leaves (16.2) was found from 25 cm x 25 cm at final harvesting. So, optimum spacing 25 cm x 25 cm would be more suitable considering different points of view. Moreover, the treatment combinations 25 ppm GA3 with 25 cm x 25 cm exhibited highest benefit-cost ratio (2.04) than other treatments. Conclusions: It is concluded that the combinations 25 ppm GA3 application with 25cm x 25cm spacing would be optimum for better growth and yield of lettuce
