Inceptisols umumnya memiliki tingkat kesuburan tanah rendah sampai sedang. Upaya peningkatan ketersediaan hara tanah Inceptisol dengan pupuk anorganik NPK perlu diimbangi dengan aplikasi pupuk hayati dan amelioran organik. Percobaan ini bertujuan untuk mengurangi dosis pupuk NPK dengan menggunakan pupuk hayati dan amelioran organik serta meningkatkan hasil tanaman jagung. Percobaan dilakukan di Pasir Banteng, Kabupaten Sumedang. Penelitian menggunakan RAK faktorial. Pupuk hayati dengan amelioran organik sebagai faktor pertama sebanyak empat taraf: tanpa pupuk hayati dan amelioran (kontrol), diberi pupuk hayati, amelioran organik, dan gabungan keduanya. Faktor kedua yaitu dosis pupuk NPK empat taraf: 100%, 80%, 60%, 40% NPK dosis anjuran. Dilakukan tiga kali ulangan. Hasil penelitian menunjukkan terdapat interaksi antara pupuk hayati, amelioran organik, dengan pupuk NPK terhadap tinggi tanaman, N-total tanah, bobot tongkol berkelobot dan tanpa kelobot. Pemberian pupuk hayati dan amelioran disertai pupuk NPK 100% dan yang tanpa diberi amelioran menghasilkan bobot tongkol tanpa kelobot sebesar 1.089 g dan 1.064 g per tanaman. Pemberian pupuk hayati dengan amelioran dan pemberian pupuk NPK 100% menghasilkan bobot pipilan per tanaman 526,08 g dan 539,08 g. Aplikasi pupuk hayati dan amelioran organik belum mampu mengurangi dosis penggunaan pupuk NPK pada Inceptisols asal Pasir Banteng. Inceptisols generally have low to moderate soil fertility. The effort to increase the nutrients availability in Inceptisol through the application of NPK fertilizers need to be balanced with biofertilizers and organic ameliorants. This experiment aimed to reduce the dose of NPK fertilizer by using biofertilizers and organic ameliorants and to increase maizeyields. The experiment was conducted in Pasir Banteng, Sumedang Regency. The factorial RBD was used. The biofertilizer with organic ameliorant as the first factor: no biofertilizer and no ameliorant (control), biofertilizer, organic ameliorant, and combination of both. The second factor was dose of NPK fertilizer: 100%, 80%, 60%, 40% of recommended NPK dose. It was repeated three times. The results showed that there was interaction between biofertilizer, organic ameliorants, with NPK fertilizers on plant height, N-total soil, weight of cobs with and without husk. The application of biofertilizer and ameliorant with 100% NPK fertilizer and without ameliorant were 1,089 g and 1,064 g of cobs without husks, respectively. The application of biofertilizer with ameliorant and 100% NPK fertilizer had a grain weight of 526.08 g and 539.08 g, respectively. The application of biofertilizers and organic ameliorants has not been able to reduce the dose of NPK fertilizer on Inceptisols from Pasir Banteng.

New wetlands field generally has low productivity, so a technology is needed for improve productivity. New Superior Variety (NSV) is a technology that is considered easy to be adopted by farmers, so knowing a NSV that is able to adapt to the characteristics and conditions of new wetlands field is a must. The study of adaptive NSV on new wetlands field in Boven Digoel Regency is still limited so that the NSV recommendation for farmers is also still limited. The purpose of this study was to examine the growth and production of new superior varieties on the new wetlands fields in Boven Digoel Regency. The study was conducted on new wetlands in Asiki Village, Jair District during April-August 2019. Randomized Complete Block Design was employed with 3 replications using Inpari 36, Inpari 37, Inpago Rindang 1, Inpago Rindang 2 dan Inpara 8. The results showed different varieties perform different agronomy characters observed (plant height, number of tillers, panicle length, number of grains per panicle, filled grain, per panicle, empty grain per panicle and 1000 grain weight). Inpari 37 produced 5.3 ton/ha Dried Unhulled Rice, the highest production compared to other varieties, so that it could potentially be developed in Boven Digoel’s new wetlands field. Productivity may still be increased by improving soil fertility conditions.

ABSTRACTTalas banana (Musa paradisiaca var. sapientum L.) has a high economic value. However, because of slowly breeding, a quick way of propagation: i.e. in vitro is required.Peatlands inSouth Kalimantan are quite large and has potential to be used for planting area of Talas banana. The acclimatization of seedlings planted on the peatsrequires more fertilizers, considering the low nutrient content of the peats. This study aims to determine the chicken manure and nitrogen-phosphor-potassium (NPK) fertilizer on the growth of Talasbanana acclimatized in peatlands. This study applied a randomized block design (RBD) factorial: (1) the amount of chicken manure (K), namely: k1 = 5 t ha-1; k2 = 10 t ha-1; k3 = 15 t ha-1; k4 = 20 t ha-1, and (2) the amount of NPK fertilizers (P), namely: p1 = 200 kg ha-1; p2 = 250 kg ha-1; p3 = 300 kg ha-1. Therefore, 12 treatments. DITAMBAHKAN TERDAPAT 12 PERLAKUAN. All treatments have 3 replicates. The results of the experiment showed that there was no interaction between doses of chicken manure with NPK. The amount of chicken manure 5 t ha-1 resulted in the highest increment of plant height observed at 2nd, 4th, 6th, 8th, 10th and 12thweek after planting, increment of stem diameter, addition of leaf number, width and length of leaves.The results of experiment also revealed that the best increment of plant height observed at 8th week after planting and stem diameter observed at 4th week after planting was obtained by 250 kg ha-1of NPK fertilizer application.

Hybrid rice has genetic traits such as sturdy stems, long and bushy dwarfs, short lifespan of 110-145 days, has large number of tillers, and leaves are dark green. Productivity of hybrid rice reached 6-12 tons-1ha. To obtain maximum production, hybrid rice varieties should be planted on fertile land, nutrients must be available, adequate irrigation, integrated pest management, and crop management should be done well. Efforts that can be done is to provide a balanced fertilizer, one with the use of appropriate doses of NPK fertilizer. The research was conducted in Gedangan Village, Grogol District, Sukoharjo Regency in May to August 2017 using Randomized Complete Block Design (RCBD) design with 2 factors of treatment, is the dosage of NPK fertilizer and rice varieties and replicates 4 times. The results showed that the treatment of various doses of NPK fertilizers and rice varieties increased the results of all observation variables, except in the variable of plant height and yield per harvest. While the interaction between the two treatments almost increased the results of all observation variables except for plant height and yield per harvest.
