The analysis of production function and farm marketing efficiency of pineapple (Ananas comosus L Merr) in South Sumatera Province, Indonesia

This study was based on input and output obtained from 200 random samples of pineapple farm in South Sumatera Province. The major objective of the study is to analyze the input allocation of pineapple farm from six angles: cultivated area, seed, man power, chemical fertilizer (Urea, TSP, and KCL), manure, and insecticide. The result of Cobb Douglas production function approach indicated that, inputs had not been used...

Productivity and economic analysis of sunflower/maize crop rotation under different levels of salinity and nitrogen

This study aimed to assess the effect of salinity of irrigation water and nitrogen fertilization on yield and oil production of sunflower, cv. BRS 324, and yield of maize hybrid AG1051, as well as economic analysis of crop rotation (sunflower/maize). The experimental was laid out in a randomized complete block design in split plot with five replications, the plots were formed by five levels of electrical conductivity of...

In silico identification of putative expressed sequence tag (EST)-simple sequence repeats (SSRs) markers of resistance to Meloidogyne spp. in common bean

Expressed sequences are important sources in the development of functional heterologous microsatellite markers in phylogenetic related groups, that is, soybean and commom bean. The objective of this work was to identify and characterize expressed sequence tag (EST)-simple sequence repeats (SSRs) in silico candidates of resistance to Meloidogyne spp. in common bean. Seven DNA sequences from soybean associated with...

Poultry manure influenced growth, yield and nutritional quality of containerized aromatic pepper (Capsicum annuum L., var ‘Nsukka Yellow’)

‘Nsukka Yellow’ pepper is an aromatic pepper (Capsicum annuum) grown in specific rural locales in southeastern Nigeria. Ripe fruits are predominantly yellow and are exported to Nigerian cities where they command premium price. The need to develop appropriate technologies for adaptation and cultivation of ‘Nsukka Yellow’ pepper in cities where there are scarcity of agricultural lands motivated...

Sources of phosphorus for the establishment of palisade grass (Urochloa brizantha (Hochst. ex A. Rich.) R.D Webster)

In Brazil, about 80% of the 60 million hectares of pasture are in some state of degradation. Among the causes of this degradation is the lack of investment in liming and fertilization at the time of planting. Phosphorus is especially critical because it stimulates root growth in the establishment phase of forage growth. The objective of the study was to evaluate different sources of phosphorus in the formation of...

Fractal analysis in the description of soil particle-size distribution under different land-use patterns in Southern Amazonas State, Brazil

Understanding the variability of soil properties is crucial to identify areas susceptible to physical degradation. The soil degradation is often determined by the current state of the soil structure, that is, the aggregate size distribution. Therefore, this article suggested evaluating aggregate sizes’ distribution by using the fractal theory. The goals were: (i) to calculate the fractal mass dimension of soil...

Propolis extract coated in “Pera” orange fruits: An alternative to cold storage

Orange (Citrus sinensis) is a non-climacteric fruit that can be stored for long periods. However, the development of physiological and phytopathological disorders limits its postharvest storage. The objective of this study was to evaluate the effects of coating orange with propolis extract on the physicochemical characteristics of the ‘Pera’ orange during storage under ambient temperature. The fruits were...

Rooting of African mahogany (Khaya senegalensis A. Juss.) leafy stem cuttings under different concentrations of indole-3-butyric acid

Vegetative propagation were studied in order to implement Khaya senegalensis A. Juss. wood production, conservation and genetic improvement programs. The objective of this research work was to establish the requirement as well the appropriated concentration of indolbutiric acid (IBA) in the K. senegalensis leafy stem cuttings to produce new plants. The basal end of the leafy stem cuttings were immersed, at first...

Effect of Vitex agnus-castus on in vitro digestibility in ruminant

The objective of this study was to evaluate the effects of different levels of Fructus agni-casti (FAC) on in vitro gas production (GP), organic matter digestibility (OMD) and net energy lactation (NEL) using an in vitro gas-production method. Two rumen-fistulated sheep were used in the experiment. The sheep were fed 60% alfalfa hay and 40% concentrate feed twice daily. Five different levels of FAC were added to the...
