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.

Abstract

Aminah IS, Moelyadi Y, Rosmiah R. 2019. Application of organic fertilizer enhanced with bio fertilizer in growth and production of maize in tidal swamp. In: Herlinda S et al. (Eds), Prosiding Nasiobal lahan Suboptimal 2-019, Palembang 4–5 September 2019. pp 330-337. Palembang: Unsri Press. Organic fertilizers have the ability to increase soil fertility both physically, chemically and biologically, on the other hand the content of organic matter is not enough to meet nutrient requirements for plants, so it is necessary to add biological fertilizers containing bacteria that can help provide nutrients. This study aims to determine the types of organic fertilizers enriched with biological fertilizers with different concentrations in corn plants (Zea mays L.) in tidal land. This research has been carried out on the ground of farmers in Purwosari Village, Tanjung Lago Subdistrict, Banyuasin Regency, South Sumatra Province held from May to August 2018. The research method uses Split Plot Design with 12 treatment combinations and 3 replications. The treatments are as follows: Organic fertilizer (K), K1=chicken manure compost, K2=Cow compost, K3=Rice Straw Compost, and Biological Fertilizer Dosage, H0=No Biofertilizer, H1= 10ml/litter, H2= 15 ml/litter, H3=20 ml/litter. The variables observed in this study were plant height (cm), number of leaves (strands), leaf area (cm), root length (cm) and dry weight of plants (g). The results showed that the combination of the treatment of chicken manure compost and 20 ml/liter biofertilizer doses gave the highest yield with an average yield of 5.58 kg/plot or equivalent to 7.3 tons/ha of  corn shelling.Keywords: biological fertilizer, corn, organic fertilizer
