Abstract

Moelyohadi et al., 2012. The Use of  Various Types of Biofertilizers on Cultivation of  Nutrient Efficient Corn Genotypes(Zea mays L.  in Marginal Dry Land. JLSO 1(1):31-39.The study aimed at  obtaining nutrient efficient corn genotypes that give the best response to various types of biological fertilizers at low-level doses of chemical fertilizer in marginal drylands. This study was conducted in the field trials of Agro Techno Park (ATP), the Ministry of Research and Technology, South Sumatra from May to September 2011. The experimental design used was SplitPlotdesign  with three replications. The main plot treatments consisted of: (H0): without biofertilizer, (H1): biofertilizer:-mycorrhizae and (H2): BPF biological fertilizers. Subplot treatments, consisting of three corn genotypes for the selection of efficient nutrient properties, are genotypes  B-41 (G1), L-164 (G2), S-194 (G3)  and onehybrid variety:BISI-816 (G4) as agenotypecomparator. Alltreatmentunitswere givenlow dosesof chemicalfertilizerthat is 50% of theATPstandarddose(200kgUrea, SP-36 50kgand 25kgKClha-1).  The results showed that mycorrhizal fertilizer produced the highest corn production, which is 6.08 ton dry seed / acre and genotype B-41 shows a more adaptive growth in marginal dry land with a production  of 7.27 tons of dry  seed /acre  and the combined treatment of mycorrhizal fertilizer and genotype B-41 gave the highest production  of 8.57 tons of dry seed / acre

Abstract

This study aimed to study the growth and yield of maize crop nutrient  efficient  selection against  the  combination of different types of organic fertilizers and bio-fertilizers at low dose levels of chemical fertilizer on marginal dry land for the development of technological innovation fertilization on maize crops to reduce the use of chemical fertilizer on marginal dry land. This study was conducted in the field trials of Agro Techno Park (ATP), the Ministry of Research and Technology, South Sumatra from  January  to May  2012.   The experimental design used was SplitPlotdesign with three replications.   . The main plot treatment was dose levels of chemical fertilizer consists of : P1 = 50 % standard dose of ATP ( 200 kg urea , 50 kg SP36 and 25 kg KCl/ha ) and P2 = 25 % standard dose of ATP ( 100 kg urea , 25 kg SP36 KCl and 1.25 kg/ha) . treatment subplot , is the combined delivery of this type of organic fertilizer + biofertilizer types , comprising : KHO = control ( without organic fertilizer + biofertilizer ) , KH1 = composted cow manure + mycorrhiza , KH2 = composted cow manure + bacterial phosphate solvent , KH3 = composted chicken manure + biological mycorrhizae , KH4 = composted chicken manure + bacterial phosphate solvent , KH5 = compost straw corn + mycorrhizae , KH6= composted maize straw + bacteria phosphate solvent , KH7 = compost Legume cover crop ( LCC ) + Mycorrhiza and compost KH 8= legume cover crop (LCC) + solvent bacteria Phosphate.  The results showed that chicken manure compost fertilizer + fertilizer mycorrhizal give the best effect on the growth and yield of dryland corn yields marginal with an average of 9.70 tons of dry cobs/ha and the combined treatment of chemical fertilizer at 50 % level and composting chicken manure + mycorrhizal give the best effect on the growth and yield of maize in marginal dry land , with an average yield reached 10.51 tons of dry seed/acre.
