The Level of Social Capital And Its Effect on The Participation of Farmers on Goat Livestock Business Development In Jeneponto Regency South Sulawesi Province-Indonesia

Tanri Giling Rasyid., ST.Rohani, Muhammad Aminawar, Muhammad Darwis

Abstract the criteria for livestock business development determined by Jeneponto Regency Head are able to contribute significantly or potentially high to goat production. In goat farming business, goat farmers are usually joined in groups. One of the factors that influence the development of a group is the social capital and the level of participation within the group itself. This study aims to (1) describe the level of social capital of goat breeders; (2) to describe the participation of goat breeders; and (3) analyze the influence of social capital with goat breeder participation level in Jeneponto Regency. The method used in this research is descriptive research. From 11 districts in Jeneponto Regency, 3 districts have the largest number of goats, Tamalatea district (32,516 tails), Bontoramba district (19,336 tails), Kelara district (15,873 tails) (BPS Jeneponto, 2016). From each district, 25 farmers were chosen as the respondent or the sample farmer so that the totals were elected 75 goat farmers. The sampling technique was done randomly simple. The research data collected cover the characteristics of social capital of farmers (trust, network, and social norm). The results showed that (1) the level of social capital in the goat breeder group in Jeneponto Regency is still low from all aspects of social capital ie manual trust, reciprocity, and networking; (2) goat breeder participation rate in Jeneponto Regency is in high category; and (3) social capital significantly affect the participation of goat farmers in Jeneponto Regency.

Effect of Green Synthesized Magnetite (Fe3O4) Nanoparticles on the Green Peach Aphid Myzus persicae Sulzer (Homoptera: Aphididea) Longevity and Fecundity

Hassan M. Asoufi, Tawfiq M. Al-Antary, Akl M. Awwad

Abstract In this study, the efficacy of green synthesized magnetite Fe3O4 nanoparticles against the green peach aphid longevity and fecundity was evaluated under lab conditions. The green peach aphid was reared on pepper plant in growth chamber for 10 generations. The LC50 of synthesized magnetite nanoparticles was determined on the early and late nymphal instars of the green peach aphid after 24 hr. The effect of different concentrations of green synthesized magnetite nanoparticles against the green peach aphid longevity and fecundity was evaluated for three subsequent generations using one day old nymphal instar from surviving adult of those treated with LC50 concentrations of Fe2O3NPs and still alive after 48 hrs was investigated. The result obtained from this study revealed that the potential of magnetite nanoparticles against early and late nymphal instars of the green peach aphid, LC50 was 220 and 500 ppm, respectively. Magnetite nanoparticles showed significant decrease in longevity and fecundity of the green peach aphid. Results of this study provide promising new nanoparticles; magnetite
which may be useful in the management of the green peach aphid and environmentally safe.

Edaphic Relationships Among Tree Species in the Kapur (Dryobalanops aromatica Gaertn.f.) Forests of Peninsular Malaysia

Nik Norafida, N.A., Nizam, M.S., Wan Juliana, W.A. & Faezah, P.

Abstract Environmental controls which are dependent on the soil are known as edaphic factors. Variations in soils supply as a medium in plant growth may lead to restrictions in the functioning and distribution of organisms and hence influence the structure of whole ecosystem. The edaphic essentials for plant growth are dependent on the physical and chemical characteristics of soils. A study was conducted at three “Kapur” forests in Peninsular Malaysia, to determine association between the tree communities and soil properties. Tree inventory and soil sampling were carried out in 30 plots (50 m × 20m each) established within the three forests, namely, the Bukit Bauk Forest Reserve (BBFR) in Terengganu, Lesong Forest Reserve (LFR) in Pahang, and Kluang Forest Reserve (KFR) in Johor. All trees with diameter at breast height (dbh) of 5 cm and above were measured, tagged and identified, whilst soil samples were analysed for texture, pH, base cations, available nutrients (that included of Mg, P and K) and inorganic nitrogen (ammonium-N and nitrate-N).The most commonly occurring species came from the family Euphorbiaceae, followed by the families Myrtaceae and Lauraceae. Density-wise, Dipterocarpaceae and Dryobalanops aromatica recorded the highest density at family and species levels, respectively. The most important species based on the highest important value index (IVi) was Dryobalanops aromatica (Kapur) with index values of more than 15%. Soil analyses showed that the soil texture was dominated by sandy clay loam, and the percentages organic matter content at all sites were low with mean percentages in the range of 4.69-6.06%. In general, the soils of the study sites were acidic, whilst available nutrients occurred in the range of low to high concentrations. Canonical Correspondence Analysis (CCA) showed a low species-environment correlation. Nevertheless, the CCA species ordination diagram showed that several tree species appeared to be closely associated with soil factors such as pH, inorganic nitrogen and available nutrients of Mg, K and P, thus, indicating the role of soil factors in influencing floristic distribution patterns of vegetation communities in the Kapur forest habitats.

Response of Maize to Integrated Nitrogen Management and Its Application Time

Talha Jan, Nangial Khan, Farooq Nawaz, Mehran Ali, Salman Ali and Junaid Ahmad

Abstract Integrated nitrogen management and its application at suitable time is critical for increased soil productivity and crop sustainability. The objective of the current study was to evaluate the effect of crop residues, its application time and suitable application stage for nitrogen fertilization on yield of maize (Zea may L.) The experiment was conducted during summer 2014and experimental design was randomized complete block (RCB) design having four replications. Cereal and legume residues at the rate of 5 t ha-1 each were applied at three different stages, i.e. 15 days before sowing, 7 days before sowing and at sowing while fertilizer nitrogen was applied at the rate of 100 kg ha-1in full and split doses at various growth stages (sowing and V6 stages). The results showed that legume residues resulted in higher grains ear-1 (298), 1000 grains weight (204 g) and grain yield (2290 kg ha-1). Among nitrogen application stages, split application resulted in maximum ears plant-1 (0.87), grains ear-1 1000 GW (208 g), stover yield (8269 kg ha-1) and grain yield (2414 kg ha-1). Results presented that cereal residues and full dose of nitrogen at any stage performed poorly and resulted in least values of these parameters. It is concluded that legume residues at the rate of 5 t ha-1 along with the split application of nitrogen at the rate of 120 kg ha-1 maximized the productivity of maize.
