Abstract

Low soil fertility is the most important factor constraining corn (Zea mays L.) yield in marginal land due to soil acidity.  Corn cultivars with high nutrient efficiency and tolerance to soil acidity offer an alternative to solve the problem.  A Complex population had been formed by natural crossing among six cultivars/line expected to carry the nutrient efficiency character; Sukmaraga, Lamuru, Srikandi Kuning, Bisma, Bayu, and Toray and used as a genetic material in this study.  The objectives were (i) to evaluate the agronomic performance of complex population in marginal land under limited nutrient supply, (ii) to select the superior entries in each population for nutrient efficiency, and (iii) to identify the characters relate to yield (nutrient efficiency).  The selection of nutrient efficiency was based on the ear dry weight produced per plant (yield).  The experiment was conducted in marginal land at Agro Techno Park, Indralaya, South Sumatra in January to April 2008.  Randomized Complete Block Design with four replications was used.  The treatment was number of entries that grouped into six populations based on a female parent.  Plants were fertilized with Urea, SP-36, and KCl at 30% of standard rate.  Sukmaraga population had the best agronomic performance among six populations evaluated. The superior entries selected were top 10% of the total entries in each population with ear weight more than 150 g. All the characters (ear length and diameter, plant height, leaf chlorophyll, leaf numbers above the ear, and ear leaf area) related to yield (nutrient efficiency) but plant height is the only character measured before anthesis.  The results suggest that Sukmaraga population had use nutrient more efficiently than the other populations and plant height may be used as selection criterion in early screening large numbers of corn entries or lines for nutrient efficiency.        Key words:  Agronomic characters, corn, marginal land, nutrient efficiency

Abstract

ABSTRACTSubmergence tolerance is plant adaptation to anaerobic or hypoxia condition without significant damage.  Changes in morphophysiological characters of rice plant are often related to the plant adaptation to submergence stress.  Fertilization might affect  plant morphophysiological changes under submergence stress. The objective of this research was to study the effect of rice varieties and fertilizer application on the growth and morphophysiological changes under submergence stress. The experiment was arranged in factorial completely randomized block design with six replications. The first factor was rice varieties consisted of Inpara 5 (V1) and IR64 (V2), while the second factor was fertilizer application consisted of  without  fertilization (P0) and with fertilizer application (P1). Submergence stress was applied on 28 days old seedlings for 7 days.  The results showed that fertilizer application increased aerenchyma formation and plant N content of both IR64 and Inpara 5 varietes.  Inpara 5 variety had higher relative chlorophyll content, relative carbohydrate content, and relative plant dry weight thant IR64 variety at 7 days after submergence stress.    Keywords: fertilization, morphophysiology, submergence stress, tolerance

Abstract

ABSTRACT Changes in Point of Zero Charge and Negative Charge of Coal Fly Ash due to Chicken Manures Addition Fly ash, coal combustion residue of thermal power plants, has been regarded as a problematic solid waste all over the world. Due to the environmental problems created by large-scale fly ash generation, efforts are being made to recycle these materials, such as to improve soil fertility as an ameliorant. In the present study, the possibility to improving the status of point of zero charge (PZC) and negative charge in fly ash (FA) and chicken manure (CM) mixtures was investigated. Fly ash was mixed with chicken manure composition of 0, 25, 75, and 100 % FA (w/w basis) and incubated for 15, 30, 45, and 60 days. Treatments arranged in factorial completely randomized design with 3 replicates. The results showed that the compositions of FA-CM and incubation period significantly affect the status of TMN, negative charge, P sorption and available-P. The mix of 50% FA with 45 days incubation tend to have a lower PZC and P sorption and higher negative charge and P-available. This composition could be use as an amelioran to improve the soils chemical properties in terms to decrease PZC and increase negatif charge, and it is necessary for further research.   Keywords: chicken manure, coal fly ash, point of zero charge, negative charge

Abstract

Ketersediaan P tanaman yang rendah akibat tingginya jerapan P merupakan kendala utama pada Ultisol. Penelitian ini bertujuan untuk mempelajari pengaruh pemberian campuran abu terbang batubara-kotoran ayam (ATB-KA) terhadap perubahan jerapan dan ketersediaan P pada Ultisol. Perlakuan yang diterapkan pada percobaan ini meliputi dosis ATB-KA dengan komposisi 1:1 (b/b), yaitu 0, 15, 30,45, dan 50 ton ha-1, dan dosis pupuk P yang terdiri dari 0, 87, 174, 261, dan 348 kg P2O5 ha-1. Percobaan dilakukan menurut Rancangan Acak Lengkap Faktorial dengan 3 ulangan. Hasil penelitian ini menunjukkan bahwa dosis ATB-KA, pupuk P, dan interaksi keduanya berpengaruh sangat nyata terhadap nilai titik muatan nol (TMN), pH, dan muatan negatif tanah. Campuran ATB-KA dapat digunakan sebagai amelioran untuk meningkatkan pH tanah dan muatan negatif tanah. Pemberian campuran ATB-KA dosis 30 ton ha-1 dan pupuk P dosis 174 kg P2O5 ha-1 dapat meningkatkan muatan negatif tanah yang lebih baik dibanding kombinasi perlakuan yang lain. Jerapan P minimum (127,07 mg kg-1) dan P-tersedia maksimum (102,21 mg kg-1) diperoleh pada dosis ATB-KA sebesar 42,64 ton ha-1 dan pupuk P dosis 261 kg P2O5 ha-1.
