Abstract

Hasil jagung manis di Indonesia per hektarnya masih rendah. Untuk mendapatkan hasil yang maksimal, maka selain pupuk anorganik, tanaman jagung manis membutuhkan pupuk organik. Salah satu sumber pupuk organik adalah pupuk kandang kambing karena kambing merupakan bagian integral dari sistem usahatani yang diterapkan di pedesaan. Kandungan hara yang rendah dari pupuk kandang kambing menyebabkan kebutuhan per hektarnya menjadi sangat banyak dan kesulitan dalam penggadaannya. Untuk itu perlu dilakukan pengkayaan dengan menggunakan batuan fosfat, dan zeolit.  Sementara itu, nilai estetika pupuk organik diatasi dengan membentuk pupuk granul. Percobaan pengujiaan efektivitas pupuk organik di lapangan dengan menggunakan Rancangan Acak Kelompok (RAK) faktor tunggal dan diulang 3 kali. Hasil penelitian menunjukkan bahwa pengkayaan pupuk kandang kambing dengan BFA atau Zeolit dapat meningkat nilai pH, kadar C-organik dan bahan organik tanah. Zeolit meningkatkan pertumbuhan tanaman Jagung Manis pada parameter tinggi tanaman dan jumlah daun, sedangkan BFA meningkatkan diameter daun. Takaran Zeolit 4,5% dapat menghasilkan berat dan panjang tongkol paling tinggi dibandingkan perlakuan lainnya. Kata kunci: BFA, Jagung manis, pupuk organik, zeolite.

Abstract

Profitable crop production starts with a weed control program that includes pre-emergence herbicides to deliver long-lasting, residual weed control. Pre-emergence herbicides are applied to prevent the germination of weed seeds. The study was conducted to determine the effect of acetic acid as a pre-emergence herbicide on maize germination. Pots experiment was conducted on August until September 2012. The experimental design used was Completely Randomized Design (CRD) single factor in four replicates. The application of pre-emergence acetic acid at several concentration, i.e. control (no acetic acid) 0%, 10% acetic acid and 20% acetic acid. The result showed that the pre-emergence aplication at 10% and 20% of the glacial acetic acid solution lowered pH were 5,12 and 5,43 respectively at one week after application, so that inhibited maize germination. No shoots and roots were grew. This was due to the increase of electrical conductivity (EC) or electrolyte leakage caused by the high permeability of the damaged membrane of seed. The EC of control treatment was 11?S/cm g, compared to 10 and 20% treatment of acetic acid were 36 ?S / cm g and 55 ?S / cm g EC respectively. Increasing concentration of acetic acid caused the higher of protein content leaked, i.e. 7,95%, 7,32% and 7,03% respectively for without acetic acid treatment, 10% and 20% acetic acid. Acetic acid also inhibited respiration rate of maize seed, where the higher concentration of acetic acid produced the lower respiration rate, i.e. 31.63 mg/g/hour, 12.38 mg/g/hour and 2,75 mg/g/hour respectively for without acetic acid treatment, 10% and 20% acetic acid.

Abstract

Peatland in Indonesia has a potential for maize cultivation, but it has constraints that low of soil pH and of nutrient availability. Use of ameliorants from coastal sediment and salted fish waste was an alternative to improve peatlands productivity and maize yields. Objective of the study was to examine effects of coastal sediment and salted fish waste on growth and yield of maize at three kinds of soil of peatlands of Kubu Raya, West Kalimantan. This research was conducted  in  field  using  Inter-area analysis  design.  The  first  factor  was  combination  of  each ameliorants  which consisted of 5 levels, namely: 1) treatment under farmer custom at the sites (control); 2) coastal sediment of 20 Mg ha-1 + 0.75 Mg of salted fish waste ha-1; 3) coastal sediment of 40 Mg ha-1 + 1.5 Mg of salted fish waste ha-1, 4) coastal sediment of 60 Mg ha-1 + 2.25 Mg of salted fish waste  ha-1. The second factor was soil types which consisted of three levels, namely: Typic Haplohemists, Typic Sulfisaprists and Typic Haplosaprists. Each treatment was repeated 5 times. The results showed that combination of 40 Mg ha-1 of coastal sediment and 1.5 Mg ha-1 of salted fish waste was the best combination for all soil type. It increased plant height (33% - 44%), shoot dry weight (74% - 75%), number of seeds per cob (31% -110%), weight of 100 seeds (58% -71%) and dry grain weight per plant (136 % -160 %) at each soil. The highest yield was found in soil of Typic Haplosaprists (219.54 g), followed by Typic Sulfisaprists (210.72 g) and Typic Haplohemists (208.82 g).Keywords: Coastal sediment, maize, peat soils, salted fish waste [How to Cite: Denah S, BH Sunarminto, D Shiddieq and D Indradewa. 2014.

Abstract

Phytophthora capsiciis a causal agent for footrot disease in pepper and classified as a soil-borne pathogen. The inoculums of P. capsici in the soilis difficultto detect. The dynamics of P. capsici population in the soil is frequently and rapidly fluctuates and hard to detect, causing the pathogen to produce disease rapidly. The aimsof this research were todetect the pathogen P.capsici using black pepper leaf baiting and to quantify the inoculum of the pathogen P.capsici in the soil belonging to several disease intensities of the black pepper foot rot in the field. The first experiment: detecting the pathogen P. capsici using black pepper leaf baiting in the soil artificially infested using several sporangia, anda second experiment: quantification of propagul of the P.capsici in various categories of intensity on the black pepper foot rot disease in the field. The research results showed that the black pepper leaf baiting could be used to detect the existence of the propagul of P.capsiciin the soil artificially infested in various densities of sporangia.  The increase in disease intensity occurred in parallel with the greater density of P. capsici inocula in soil. The density of P. capsici inocula in the soil tended to decline when the disease intensity reached the highest level.

Abstract

The growth and yield of plants are mainly a function of the quantity of fertilizer and water. In coastal sandy soil, nutrient losses and dry soils are seriously problems. The objective of the research was to study effect of zeolite and hucalci concentrations as NPK coating materials on NPK qualities i.e. water adsorption and release of N, P and K. The research used a coastal sandy soil as media. It was conducted in a laboratory of Soil Science Department, Gadjah Mada University from July to August 2009. Experimental design used was a factorial in a completely randomized design. The first factor was hucalci concentration, consisted of 10% (H1), 20% (H2), and 30% (H3). The second factor was zeolite concentration, consisted of 25% (Z1), 50% (Z2), 75% (Z3), and 100% (Z4). NPK fertilizer (without coating) used as a control. The results showed that hucalci and zeolite had a capability to increase water adsorption and to retard the release of N, P, K. The coated NPK with hucalci 30% and zeolite 100% had the highest quality in water absorption, water retention and release of nutrients.Keywords: Coastal sandy soil, humic-calcium, NPK fertilizer, zeolite
