Judul: Respon Tanaman Jagung terhadap Kombinasi Pupuk Organik, Konvensional, Slow Release dan Waktu Pemberian pada Tanah Latosol Dramaga
Abstrak: One of the ways to improve the maize production is by effective and efficient fertilization. Improvement of the fertilizer efficiency is implemented by combination of organic, conventional and slow release fertilizer. The objective of this study was to examine the effect of a combination of organic fertilizer, conventional fertilizer, slow release fertilizer and time of application on the growth, nutrient content and production. The rates of organic fertilizer were without organik fertilizer (O0) and 2,5 ton/ha organic fertilizer (O1). The rates of conventional fertilizer were 50% of recommended rate (S1) and 100% of recommended rate (S2). The rates of slow release fertilizer were 1tablet/plant (P1), 2tablet/plant (P2) and 3 tablets/plant (P3) and the rate of application time were at 10 days after planting (T1) and application at 10 days after planting and 30 days after planting (T2). The results showed that the effect of single treatment, combination of the two and three treatments of organic fertilizer, conventional and slow release were significantly higher on the growth, nutrient content and crop production. The effect of four combinations namely organic fertilizer, conventional, slow release and application time was not significantly different on growth, nutrient content, and production. The highest production of dry grain obtained by combination of organic fertilizer, conventional fertilizer with 100% recommendation rate and slow release fertilizer with 3 tablets/plant with one application time (O1S2P3T1) namely 7.28 ton/ha. The production of dry grain on combination of organic fertilizer, conventional fertilizer with 50% of recommendation rate and slow release fertilizer with 3 tablet/plant with one application time (O1S1P3T1) as similiar to O1S2P3T1 namely 7.20 ton/ha. Based on the production of dry grain, application of slow release fertilizer with 3 tablet/plant reduced 50% of the conventional fertilizer use.

Judul: Pengaruh pengolahan tanah dan pemberian bahan organik terhadap beberapa sifat fisik tanah dan produksi jagung manis (Zea mays saccharata) pada latosol Jampang Tengah Sukabumi
Abstrak: Penelitian ini dilakukan di lahan milik Kelompok Tani Sadagori di Kampung Nangela, Kecamatan Jampang Tengah, Kabupaten Sukabumi. Penelitian ini bertujuan untuk mengetahui pengaruh pengolahan tanah dan pemberian bahan organik terhadap beberapa sifat fisik tanah dan produksi jagung manis. Penelitian ini dilakukan dengan memberikan perlakuan yang terdiri dari 4 jenis pengolahan tanah dan 3 taraf pemberian bahan organik. Keempat jenis pengolahan tanah tersebut yaitu 1) tanpa pengolahan tanah (PO); 2) pengolahan minimum (P1) yaitu pengolahan tanah selebar 20 cm di kanan-kiri baris tanaman sedalam 20 cm dengan pencangkulan; 3) pengolahan tanah 20 cm yaitu pengolahan tanah dengan pencangkulan sampai kedalaman 20 cm pada seluruh permukaan tanah; dan 4) pengolahan tanah intensif (P3) yaitu pengolahan tanah sedalam 20 cm lalu digemburkan dengan mencangkul beberapa kali. Ketiga taraf pemberian bahan organik adalah: 1) 0 ton/ha (K1), 2) 15 ton/ha (K2), dan 3) 30 ton/ha (K3). Pemberian bahan organik berupa kotoran domba yang telah matang (kering) dilakukan dengan ..dst
