Abstract

A study has been conducted on the crop-livestock integration innovation using palm oil by-products technology to support beef cattle production in 2014. The collected data consisted of (i) Socio-economic aspects, (ii) The body weight gain of cattle, and (iii) Palm oil production. These data were taken from Sri Langgeng farmers group (13 respondents) in Dharmasraya district and Tanjung Keramat farmers group (10 respondents) in West Pasaman district. The results of the socio economic aspects showed; the  average age of farmers was 39 years old, owned palm oil plantation of 2,2 and, 4,1 ha, and owned of 4.2 and 6.2 head of cattle in Tanjung Keramat and Sri Langgeng respectively. The average monthly income was Rp 1.63 million and about Rp 1.05 million derived from livestock contribution in Tanjung Keramat, and Rp 1.65 million and about Rp 1.71 million derived from livestock contribution in Sri Langgeng. Feeding a supplement of palm oil by-products increased cattle growth by about 0.14 and 0.09 kg/head/day at Sri Langgeng and Tanjung Keramat respectively. In contrast, the animals in a control treatment experienced body weight losses of -0.17 and -0.11 kg/head/day. The application of organic fertilizer from cattle manure, above the inorganic fertilizer, increased the palm oil fruit by 39.4% and 48.4%. The research proved that there is an opportunity to accelerate the adoption process of crop-livestock integration in palm oil plantation areas in West Sumatra.

Abstract

The development of the Ketapang Integrated Livestock Area (KPTK) in Linge Sub-district, Central Aceh District is one of the implementation of local poverty alleviation policies initiated by Central Aceh District Government. This study aims to determine the implementation of KPTK development as an effort to alleviate poverty in Central Aceh District. This research used survey method with data collection in the form of field observation, in-depth interview, and focus group discussion. Data were analysed using descriptive qualitative. This study found that KPTK development has become a commitment to poverty alleviation. This is found in the central Aceh district development planning system. However, in the implementation there are several obstacles to its development, namely: (1) no synchronization of activities/ programs among related sectors; (2) from a technical point of view, some physical facilities such as roads, bridges and housing and settlement enclosures have been damaged and cannot be used anymore.

Abstract

Arbuscular Mycorrhizal Fungi (AMF) can help plants by improving the uptake of low P availability acidsoils. Organic fertilizers can effect the physical, chemical and biological soil. The purpose of this research is tostudy and determine the effect of AMF and organic fertilizer on increasing yield and nutritional value of kumpaigrass in red-yellow podzolic acid soils. The study design used a completely randomized 5 x 3 factorial pattern andrepeat three times. Two factors as treatment: AMF and organic fertilizer. AMF usage consisted of three levels:control (0 g/pot), AMF (10 g/pot) and AMF (20 g/pot). The organic fertilizer usage consisteds of five levels:control (0 %), manure (50 %), manure (100 %), compost (50 %) and compost (100 %). Variables measuredincluded the width of leaves, plant length, number of tillers, the yield of forage dry matter, crude protein,phosphorus, dry matter and organic matter digestibility. The results showed that the AMF and organic fertilizer hada highly significant (P<0.01) effect for all observed variables. The interaction AMF and organic fertilizers hadsignificant effect on crude protein, phosphorus and organic matter digestibility.

Abstract

At Present our Planet is grappling with disastrous consequences of man-made environmental problems such as industrialization, urbanization, over-exploitation of natural resources, disruption of natural ecological balances, destruction of a multitude of animal and plant species for economic reasons, etc. It is observed that most of our environmental problems are manifestations of our developmental activities. Although there is no dearth of legislations on environmental protection in India, it is clearly evident that the enforcement of these legislations has been far from satisfactory. The present study tries to establish education as a useful tool for environmental conservation and sustainable development, ensuring clean air to breathe, safe drinking water and adequate supplies of clean renewable energy. This paper is mostly based on secondary data from books, research articles, periodicals and websites. It discusses the role of teacher and school in the protection of environment and promotion of sustainable development by bringing awareness on the efficient and responsible usage of the natural resources namely air, water, land, soil, forests, rivers, oceans etc. It tries to expound the ways and means to sensitize students and make them environment conscious in order to build a vibrant, healthy and pollution free India as future citizens.

Abstract

Symbiotic relationships between arbuscular mycorrhizal fungi (AMF) and plants can increase the capacity of plants to absorb nutrients and water from the soil by exploring micropores not accessible to plant roots. The arbuscular mycorrhizal symbiosis between plants and soil fungi improves phosphorus and nitrogen acquisition under limiting conditions. Recent discoveries indicate that AMF hyphae containing glomalin as glycoproteins and function unitinge the soil particles to form stable soil aggregates. Glomalin acts as an adhesive (glue) produced by AMF symbiosis with the host plant. The AMF is capable of taking nitrogen and other nutrients from a source of organic materials to produce glomalin which is transferred to the host plant. The study was conducted using nitrogen from forage materials of Tithonia (Tithonia difersifolia) which the AMF needs to produce glomalin. This study assess the need for organic N by AMF to the mycorrhizal growth effect and its effects on glomalin. The study use sterile medium sand and zeolite mixture (w/w 1:1) in pot culture experiments with the corn as the host. For treatments using N derived from Tithonia are five doses, namely 0, 10, 20, 30, and 40 mg of N Tithonia each pot. At  the time of planting, the corn roots inoculated with AMF spores of the two species, namely Glomus luteum and Glomus versiforme. We show that a positive mycorrhizal growth response (MGR) was observed only in the dose of range 20 to 30 mg N. This response did not appear to be affected by high nitrogen supply. Our results also show that in Glomus luteum at the dose of 20 mg N produce glomalin highest, namely 2.60 mg.g-1 in the planting medium. Glomus versiforme has produced glomalin is 2.38 mg.g-1 at the dose of 30 mg N. The AMF species did not significantly affect the results of glomalin, while the use of N from forage materials of Tithonia significantly influenced the production of glomalin.

Abstract

The regional approach in agricultural development has only been limited to the concept and has not been implemented in real terms. Various forms and models of agricultural development policy using the regional approach cannot prove that the indicators of regional approach have existed and been applied in agricultural areas. The development of agriculture so far has only been sectoral. This indicates that the concept of agricultural development through regional approach has not been implemented in real condition. In development through regional approach, the synergies among sectors and among economic activities are compulsory. The production central area (PCA) approach is one of the agricultural development approaches based on regional economic development theory. This research aimed to assess how area production center as a model of agricultural development that had considered regional concept, could be success in developing regions. The respondents were layer hen breeders residing in PCA location and Non PCA (50 respondents each).The study reveals that the value of agglomeration profits of large scale economies (SEI), localization economies (LEI), capital and labor showed positive and significant effects on layer hen production at PCA location. To further increase commodity production in PCA, the agglomeration profits as a regional approach variables should be part of the PCA analysis to improve productivity, efficiency and provide added value for farmers/breeders.

Abstract

In modern cultivation processes indiscriminate use of pesticides and fertilizers, has led to substantialpollution of soil, air and water. So, there is an urgent need to solve the problem. Rhizobacteria are bacteria thatcolonize plant roots, and these bacteria are known to stimulate growth and thereby reduce incidence of plantdisease by direct and indirect mechanisms. A total of 136 rhizobacteria isolates were isolated from differentrhizosphere soils in central areas of production of onions in Indonesia. These isolates were screened for theircapability to enhance growth and protect onions against bacterial leaf blight disease-caused by Xanthomonasaxonopodis pv.allii. The results showed that ten isolates can enhance growth and protect onions against bacterialleaf blight diseases. Five isolates were isolated from West Sumatra, four isolates from Java and one isolated from North Sumatra. All isolates produced indol-3-acetic acid with different concentrations. Molecular identification of ten isolates belong to Bacillus sp, Pseudomonas sp, Stenotrophomonas sp and Serratia sp.

Abstract

This study aims to assess the performance of farming practices of Lampai Kuning rice as an improved variety. Data were collected using survey method that relied upon primary data generated during the 2016/2017 production season. Data were collected through the use of a set of structured questionnaire administered on thirty farmers in Nagari Aie Angek, Sijunjung Regency. Stata version 12 was used to test the stochastic frontier model to measure the efficiency of Lampai Kuning rice.The results showed that the use of manure and Urea had negative effect on the Lampai Kuning rice, while the use of NPK had positive effect. The level of technical efficiency of Lampai Kuning rice was very low at the 0,55 level. The study reveals that large land size led to high Lampai Kuning rice production. Farmers could double their rice production by using factor of production appropriately.

Abstract

At the end of 2015, this study has been conducted to describe the planning; process; and evaluation of collaborative training using a comparative approach, 220 and 44 beef cattle farmers participated as informant in both types of - collaborative and non-collaborative training respectively. Fifteen informants representing stakeholder provided primary data. Both primary and secondary data were analyzed by using qualitative and quantitative approaches. The results showed that planning was based on an effort to accomplish the discrepancy of cattle farmer technical competency to perform breeding program. Process of conducting collaborative training focused on group management and keeping beef cattle. In non-collaborative training was on recording technics to prepare the issue of breeding cattle certificate. Collaborative training was assisted by a number of stakeholder facilitators, but, non-collaborative training was carried out by facilitators from an institution. Improvement of farmer technical competency has shown by adding of 58.41 % of cattle population, although there was an increasing of participant cognitive domain by 43.53 % at collaborative training. The recommendation advised that management and keeping cattle technical competency are continiously acquired for the half of groups (54.5%), while recording improvement should be taken into account at all groups (100 %).
