Abstract

Current research was conducted with the objectives to identify the utmost traits that may be beneficial for the higher productivity of the grains on high protein content genotypes lines by path coefficient. Path coefficient can define coefficient correlation directly and indirectly to gain information about nature relationship between yield component and protein content to grain yield. Research material consisted of 61 selected plants from G39×Ciherang and 66 selected plants from Mentik Wangi×G39 at F4 generation. Plants were planted in Banyumas in May 2011. Number of panicles per plant, panicle length, 1000 g of grain weight, percentage of filled grain per panicle, protein content, and grain yield were correlated by using Pearson correlation and were followed by path coefficient. Number of panicles per plant, panicle length, 1000 g of grain weight, percentage filled grain per panicle, and protein content were used as dependent variable, while grain yield was used as independent variable. The result showed that protein content in both populations was not correlated with all yield components. The numbers of panicles, followed by panicle length, had highest positive direct effect to yield. The number of panicle was a positive mediator variable to yield from another variable.Keywords: correlation, direct effect, indirect effect, mediator variable, path analysis

Abstract

Physical characteristicsare among soil propertiesaffecting the susceptibility to erosion.  Determination of physical characteristics of Ultisol was aimed to evaluate the dynamics of soil properties as well asthe impact on soil erosion and runoff (RO) during soybean cultivation in wet tropical area.  Soybean was planted within erosion plots (18 m2)  at 25% slope in UltisolLimauManis (having > 5000 mm annual rainfall).   Soil samples for physical properties (soil texture, bulk density, total pore, permeability, aggregate stability,and organic carbon) as well as amount of RO and soil loss were analyzed at 5 different times (stages) during the cultivation.  The results showed that there was fluctuation in physical properties of Ultisol during the cultivation. Likewise, the amount of runoff and soil loss also changed during the study.  Among the physical properties analyzed, the aggregate stability index of the soil highly correlated to the amount of RO (R2=0.73) and soil loss (R2=0.94).  Amount of RO and soil loss was controlled by soybean development at the average rainfall intensity ≤ 36 mm/day, but not at rainfall intensity >36 mm/day.  It is suggested not to open heavily clayey-low OC soils for seasonal crop farming during rainy season in wet tropical area. Keywords: soil physical properties, Ultisol, erosion,runoff, soybean cultivation

Abstract

The study was addressed to investigating the effect of cow manure application rate on organic rice growth and yield in the first cropping season. The study was conducted from January to April 2012 in Blora, Central Java, Indonesia. The experiment was arranged in Randomized Complete Block Design, consisting of four treatments and four replications. There were two types of control treatments i.e. organic fertilizer treatments (statistically analyzed) and conventional fertilizer (not statistically analyzed). The treatments were corn biomass, corn biomass+cow manure (7.5 tons ha-1), corn biomass+cow manure (10 tons ha-1) and cow manure (10 tons ha-1) with square spacing of 20 cm x 20 cm. The organic control treatments were corn biomass+sheep manure (7.5 tons ha-1) with spacing of 20 cm x 20 cm and corn biomass+cow manure (7.5 tons ha-1) with double-row spacing of 40 cm x 25 cm x 15 cm. For every treatment, the rate of corn biomass was 3 tons ha-1. All organic treatments were also added with 3 tons rice hull ash ha-1. The application of cow manure (10 tons ha-1) with square spacing or corn biomass+cow manure (7.5 tons ha-1) with double-row spacing resulted in better performance than those of other treatments.Keywords: corn biomass, grumosol, organic farming, rice hull ash, sheep manure

Abstract

An experiment in greenhouse was conducted to study the effect of biochar and fertilizer potassium against leaching and uptake of potassium on the growth of maize during the two cropping seasons. In the experiment, a randomized block design with seven treatments and three-time replication was applied, namely control (without biochar and KCl), biochar (30 t ha-1) with various doses of potassium fertilizer (0, 50, 100, 150 and 200 kg KCl ha-1) and potassium fertilizer treatment of 200 kg KCl ha-1 without biochar. The first planting used 90 kg N ha-1 basic fertilizer and 100 kg P2O5 ha-1, while the second planting fertilizer was added with 90 kg N ha-1. The results showed that biochar containing potassium was soluble and leached. The amount of potassium leached from the soil given the biochar 30 t ha-1 did not differ from that given 200 kg KCl ha-1. The amount of potassium leached was not different, ranging from 439-449 mg l-1 in the first growing season (MT I) and 16-23 mg l-1 in the second growing season (MT II) at various doses of KCl with biochar.Keywords: biochar, leaching, potassium, uptake

Abstract

Efforts to increase rice production through genetic improvement are often limited by the availability of natural diversity. That natural diversity can be improved through induced mutation. Selected characters can be observed since the germination phases, which may also indicate the plants survival under field conditions. Experimental design was arranged in split plot, with cultivars as main plot and mutagen doses as sub plot. The experiment consisted of 36 treatment combinations, with each treatment consisting of 10 replications. Data were recorded on percentage of first count, final count and germination rate. The data were analyzed using F-test by SAS 9.0 and mean separation was carried out by employing DMRT at 95 % (α = 5 %) of confidence level. The results showed that the best cultivar response for germination traits was Inpari 13, the best mutagen to build cultivar for germination traits was Gamma 150 Gy, and the best combination between cultivar and mutagen for germination traits was Inpago Unsoed 1 that was treated with Gamma 150 Gy. Keywords: gamma irradiation, germination, rice, sodium azide

Abstract

The purpose of this study was to examine the methods of intermittent irrigation and cutting height on growth and yield of ratoon rice (Oryza sativa L.). The research was conducted on alluvial soil in Malang, ca. 507 m above sea level (asl), by using split plot design. The main plot was without flooding interval of rice field i.e.0 (full flooding), 2, 4 and 6 days. The sub plot was ratoon height i.e. 0-5 cm, 10-15 cm and 20-25 cm. The result showed that there was no significant interaction between without flooding intervals and cutting height. The result of grilled dry spikelet weight of the first crop was 5.78 t ha-1.The result of second crop showed that the treatment of 0 day (full flooding) gave the highest yield (3.12 t ha-1), decreased of 46% from the first crop.The rice crop which was ratooned of 0-5 cm in height resulted the highest yield (2.95 t ha-1), decreased of 49% from the first crop.Keywords: intermittent irrigation, rice (Oryza sativa L.), ratoon, flooding

Abstract

An understanding of the structure of the soil food web is critical in determining the practices of soil fertility management based on the biological processes in tropical agricultural regions. The objectives of the study were to assess the variation in trophic level biomass and to analyze the dynamics of the energy channels on the increasing age of cocoa plantation. The characteristics of soil food web structure in smallholder cocoa plantation aged 4, 5, 7, 10, and 16 years were analyzed. The results showed that only biomass at the third trophic level increased with plantation age, but not for the biomass at the lower trophic levels. Biomass in all energy channels did not increased as well along with plantation age. We concluded that variation in the soil food web structure was more influenced by biotic factors of macro-arthropods group, such as facilitation, recolonization capabilities and accessibility in the soil habitat of smallholder cocoa plantation. Keyword: biomass, biotic, energy channel, trophic level.

Abstract

There are many clones grown in Indonesia tea plantations. The latest clones were released around 1990. The new promising clones have been bred through crossing among selected clones in Pagilaran tea plantation. The experiment aimed to select high yield and stable clone. Nine clones were grown in Kayulandak (1300 m asl) and Andongsili (1100 m asl) in Randomized Completely Block Design with three replications. The data of fresh weight per plot in 2007, 2008, 2009, 2011, 2012 were recorded. Eberhart & Russell (1966) and GGE Biplot analysis method was applied for data analyzing. The result showed that all of clones were stable over years in each location except for PGL1 and PGL3 in Andongsili and PGL15 in Kayulandak based on Eberhart & Russell analysis. Significant regression coefficient (1.18) of PGL3 implied that PGL3 was high in yield and responsive. GGE biplot analysis indicated no ideal genotype for each location. PGL10, PGL3, PGL4 and PGL 12 were recommended for Kayulandak, while PGL3 and PGL12 clones were suitable for Andongsili. Both analysis of Eberhart & Russell and GGE biplot showed PGL3 and PGL12 as ideal clone, while PGL10, PGL4, and PGL 15 clone were desireable clones.Keywords : Eberhart and Russell, GGE Biplot, tea clones, yield stability

Abstract

Field experiment was conducted in 2005 and 2006 to study response of extra-early maize variety (95TZEE-Y1) to rates of NPK (0, 40:20:20, 80:40:40 and 120:60:60 kg N:P2O5:K2O ha-1) and residual FYM (0, 5, 10 and 15 t ha-1 applied to chilli pepper the previous season) in the semi-arid zone of Nigeria.  Randomized complete block design with three replicates was used.  Higher values for soil physical and chemical properties were obtained in plots supplied with manure the previous season with soil from 2006 experiment more fertile than for the first year, hence produced 21% more grain yield. All the applied NPK rates in 2005 and except 40:20:20 ha1 in 2006 had resulted in early maize crop as compared to control.  Husked and de-husked cob and 100-grain weights and grain yield/ha were higher at 120:60:60 kg NPK ha-1.  Maize grown in plot supplied with 15 t FYM ha1 the previous year matured earlier.  Cobs and 100-grain weights and grain yield were highest in plot supplied with 10 t FYM ha1.  The 10t FYM ha-1 had 69% and 68% more grain yield than the control in 2005 and 2006, respectively.  Highest maize yield was obtained at 120:60:60 kg NPK ha-1 or 10t FYM ha-1.  All the parameters measured significantly and positively related to each other when the two years data were combined.
