The Role of Multidimensional Perceived Value, Trust and Commitment to Achieve Collaboration in West Java Agribusiness
by Niken Larasati, Mustika Sufiati Purwanegara, Fitri Aprilianty
Abstract: Indonesia has 35.7 million people who work in the agricultural sector, and most of the poverty in rural areas happens to farmers. Because farmers are the main actor in the agriculture business, there is a need to engage them in a business process through collaborative actions with all actors. One way to build a successful relationship is through perceived value, trust and commitment. While these variables are needed to stimulate a relational bond, farmers could not trust their partners because of past experience. This research aims to obtain the trust dimension from farmers and partners and to know the influence of perceived value, trust and commitment on farmers to collaborate with their partners. An exploratory sequential mixed method design was conducted. The results showed farmers could trust their partners as long as they provide clear information, important information and held accountable about the promised result. Emotional value was the only factor that had a positive effect on trust, while functional value and emotional value were factors that triggered farmers to have a commitment with their partners. Trust can affect the commitment of farmers to their partners. Both trust and commitment were tested to know their effect on collaboration. Only commitment had a positive relationship with collaboration.

PRICE TRANSMISSION: THE CASE OF UK AND USA BROILER MARKETS
by Hannah Rose, Dimitrios Paparas, Ourania Tremma, Luis De Aguiar
Abstract: The worlds poultry market has become increasingly dominated by a small number of large, highly integrated businesses, and an even smaller number of major retail outlets. The primary aim of this study is to identify whether price transmission asymmetry is present within the UK and the USA broiler market chains as an indicator of market efficiency. rnUnderstanding the market efficiency of these markets would allow policy makers to ensure that the current policies in place are working. rnResults from the error correction model found that the UK retailer price recovers at a rate of 16% per month, whilst the USA retailer prices returning at 15% per month rate. Granger causality results found that both countries have a bidirectional causality. Results from the threshold autoregressive model also show that no long run asymmetry is present within the value chains suggesting that the market is efficient. rn

Understanding the models of Indian Fruits & Vegetables supply chains A case study approach
by Arshinder Kaur, BALAJI MANOHARAN
Abstract: The purpose of this paper is to study the different supply chain models that exist in Indian perishable fresh produce supply chain. It explores the roles of different entities in various types of supply chains and to understand the issues and challenges in agri-fresh produce supply chains by interviewing these entities. A case study approach, using qualitative methods was used to study and analyse the perishable fresh produce supply chains that exist in a typical Indian metro city. It is found that supply chain members set their margins arbitrarily which leads to extreme double marginalisation at each interface of the supply chain. In government supported supply chain, which comprises of farmer markets (called as Uzhavar Sandhai), producers face a primary challenge of the location of such markets. Fruits and vegetable (F&V) supply chains differ from other supply chains by various factors including food perishability, food quality and food security where responsiveness and efficiency of the supply chain are equally important. The developing countries like India are struggling to manage the inefficiencies in domestic F&V supply chains, which result in massive wastage. It is important to study the inefficiency at each driver of F&V supply chain which results in poor performance of F&V supply chains. The study investigates the F&V supply chains with lessons for developing economies. Insights are very useful not only for the F&V supply chain stakeholders but also for policymakers in structuring efficient and responsive supply chains. Specifically, the case study approach makes it an original contribution to the theoretical and practical knowledge of F&V supply chains in Indian context by gathering viewpoints of all entities.

Role of Climate Smart Agriculture in Promoting Sustainable Agriculture: A systematic literature review
by Md Nazirul Islam Sarker, Min Wu, G.M. Monirul Alam, Md Saiful Islam
Abstract: In the face of global environmental change, the notion of Climate Smart Agriculture (CSA) has emerged as an approach which can contribute to increase agricultural production and income of poor households. This paper explores the suitability of adopting CSA practices for promoting sustainable agriculture in order to attain global food and nutritional security. It also explores the links among the components of CSA (productivity, adaptation and mitigation) and their contribution to achieving the goal of sustainable agricultural development. Despite the potential of CSA to attain sustainable agriculture, poor connections exist among the components of CSA at the field level. More importantly, the concept is sometimes poorly understood by various levels of stakeholders. In order to attain a better future, it is crucial to disseminate CSA approaches to field level by including them in academic syllabi, seminars, symposiums, and research.

Modelling the Effect of Some Operational Parameters on Grain Loss in Mechanised Rice Harvesting: A Case Study in Malaysian Paddy Fields
by Nor Azi Asminda Johari, Darius El Pebrian, SHAMILAH AHMAD MOKHTOR, Rohaida Mohammad, Amir Hamzah Ahmad
Abstract: Excessive grain loss is still a persistence problem in mechanised rice harvesting using combine harvester in Malaysian paddy fields. Therefore, this study was conducted to develop a model for predicting the effect of some operational parameters on grain loss during mechanised harvesting operation. Three operational parameters that always associated with grain loss were measured through direct field measurements on the daily harvesting operations in the sampled rice granaries. The measured parameters included field speed of combine harvester, grain moisture, and soil moisture contents. Regression and correlation analyses were employed to develop the model estimation. The results of the predictive model exposed the fitted model with a strong relationship between associated variables and established the measured parameters to determine the grain loss. The findings would be beneficial in assisting the rice farmers to predict grain loss during harvesting and minimise excessive grain loss in mechanised harvesting operations in Malaysia.
Keywords: Mechanised harvesting; grain loss; combine harvester.
Linear Programming Model for Vegetable Crop Rotation Planning; A Case Study
by Anggita Kharisma, Tomy Perdana
Abstract: This study developed a Mix Integer Linear Programming models for crop production planning. The model encompasses the crop rotation of 4 vegetables as product diversification to fulfill supermarket demand. A production system at one of the farmer groups located in West Java, Indonesia has opted as a case study. The approach of the decision was determined upon the consideration of vegetable botanical family, crop rotation issue, total available land which exceeds the demand, and total interval time for harvesting each of the commodity. The decision has been made into a weekly scheduling plan for over a year with three combinations of crop rotation scheduling which are (1) the combination of tomato and baby kenya bean (2) the combination of carrot and baby kenya bean, and (3) the combination of potato and kenya bean. This model generates a schedule based on plot and the combination of the rotation as a tool for a coordinator of the farmers' group to minimize the excess production and optimize the schedule for crop rotation. This study proposes optimization for land utilization and the right stock for farmers within a year with maximizing profit target.

Evaluation of arbuscular mycorrhiza inoculation potential for sustainable production of aerobic rice var. MR1A
by Rosina Baadu, Shamsiah Abdullah, Hendry Joseph
Abstract: A pot culture experiment was carried out to evaluate the effect of different mycorrhiza inoculants and phosphate fertiliser application on the growth and nutrient uptake of aerobic rice, Oryza sativa L. var. MR1A. The contribution of mycorrhizae has been well acknowledged in sustainable agriculture. Mycorrhizae can influence the key ecosystem process of soil aggregation, act as an acquisition of soil nutrient absorption to improve the plant growth via their hyphae and alter the morphology of a root system by forming more branches and adventitious roots that functionally extend the root system of the plant. Three different treatments of mycorrhiza applied were Glomus mosseae, commercial mycorrhiza, and co-inoculation of both treatments. Two phosphorus application levels of 0 and 300 mgkg-1 were added to investigate the influence of inoculations on the nutrient uptake by the plant. All the treatments were designed as a randomised block. The results of aerobic rice co-inoculated with G. mosseae and commercial mycorrhiza in the presence of P fertiliser exhibited a significant difference in height (135.85

by Ratnmala Bhimanpallewar, Manda Rama Narasingarao
Abstract: In recent years, agriculture solutions using robotics and the Internet of things (IoT) technology provided advanced agricultural support for farmers to produce food products with the highest yields. However, a lack of effective and efficient agricultural device has resulted in the wide adoption of this IoT technique recently. This study presents an automatic seeding and fertilizer micro-dosing robot for farmers to achieve precision farming. The automatic robotic device for seed planting and micro-dosing of fertilizer is adapted to plant various types of seed and particularly well adapted to the plant seeds with micro-dosing fertilizer. The new option controls the number of seeds and quantifies the fertilizer quantity at each dropping point. It is also able to control the distance between each dropping point. This study has implemented the proof-of-concept prototype by the IoT system to demonstrate the feasibility of the agricultural outcomes. The experiments performed in the real-world environment which showed the effectiveness and efficiency of the device under different conditions.

Effect of Antimicrobial Activity from Fermented Mature Coconut Water to Sheath Brown Rot of Rice Disease
by Mohd Zafri Ab Wahab, Nurul Basyeroh Hasan, Fatin Amirah Bakhari, Intan Sakinah Mohd Anuar, Zaiton Sapak
Abstract: Rotting of grains or sheaths caused by Pseudomonas fuscovaginae is common for mature plants and grains of seedlings. This study explored the effect of antimicrobial activity from fermented mature coconut water to understand better a certain kind of rotting in sheaths of rice plants screened against the pathogen. Fermented matured coconut water was extracted with methanol solvent demonstrated the highest activity with 20.02 mm of inhibition followed by water solvent with 10.10 mm of inhibition. Both negative controls for methanol and water-based extracts showed no inhibition activities towards the pathogen. Methanol extraction was then determined for minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC). The finding indicated that 20% (v/v) concentration was recorded as MIC and 30% (v/v) concentration as MBC for this pathogen to reduce the disease lesion length significantly (P<0.05). The findings from this study will be useful for agriculture related agencies in controlling the disease for a higher productivity of rice production.

Characterisation of humic acids in fen peat
by Janis Krumins, Maris Klavins, Raimonds Krukovskis
Abstract: Fens store significant amounts of organic matter and thus are of high importance from the perspective of the organic carbon biogeochemical cycle. Fen peat comprises moderately to highly decomposed higher plant remains with relatively high mineral matter content. Humic acids form the major part of fen peat organic matter; they are also the most refractory and recalcitrant natural substances to degradation, and thus they contain essential information regarding mire and peat development over large periods of time as well as the organic carbon biogeochemical cycle. Moreover, humic substances in fen peat are a prospective resource for applications in agriculture and other sectors. The aim of this study was to comparatively study properties of humic acids isolated from fen peat of varied botanical compositions and origins and to compare the impact of the precursor biological material on properties of the humification process and the resulting humic acids. The formation of humic acids of varied origins show similarities; however, at the same time, differences can be found in the further development of humic acids, depending on the environment in which they are present.

Agro-Tech Ontology (ATO): A Solution for Accelerating Agricultural Productivity in the State of Rajasthan, India
by Sapna Newar, Gordhan Saini, Vaishali Singh
Abstract: Development of agriculture and reducing gaps between regions with regard to the efficiency of the agricultural system requires a deeper understanding of regional disparities. In this paper, we examine inter-district disparities in agricultural development in terms of labour Productivity. The role of selected indicators related to agricultural productivity, mechanization, technological aspects are analysed. We use historical data of 33 districts of Rajasthan from 1990 to 2014. The study reveals that the labour productivity is highly influenced by use of modern agricultural inputs. The paper discussed the problems associated with agriculture development in the state. We have examined a worsening land-labour ratio in the underdeveloped districts due to increasing population pressure on cultivated land. Along with increasing number of agriculture workers the use of other agricultural inputs like total cropped area, total irrigated area, cropping intensity and rainfall showed a downward trend in underdeveloped districts. A deeper analysis revealed that the proper and timely dissemination of information relevant to the context of agriculture workers is very important. The study proposes an Agro-Tech Ontology (ATO) to disseminate the required information to the agriculture workers in Rajasthan. Policy implications are discussed.
Keywords: Labour Productivity; Agriculture Productivity; Agro-tech Ontology (ATO); Agriculture workers; Regional Disparities; Inter-district Disparities.
The Use of Yogurt bacteria in Increasing the Growth Performance of Diseased Paddy
by Nadia Salim, Siti Sarah Jumali
Abstract: There is no report on the use of the yogurt bacteria Lactobacillus bulgaricus as a plant growth promoter, especially in increasing the growth performance of paddy. Lactobacillus bulgaricus is a widely used lactic acid bacterium in making yogurt for commercial consumption due to its probiotic properties. Some Lactobacillus spp such as Lactobacillus casei and Lactobacillus plantarum are used in effective microorganisms in fertilizers to promote better growth performance in plants while reducing bacterial infection. With this background, in this study, the effects of L. bulgaricus isolated from yakult on the growth performance of Bacterial Leaf Blight (BLB) diseased paddy were investigated. The applications used on the Bacterial Leaf Blight (BLB) to the diseased paddy were 103 cfu (Treatment 1), 104 cfu (Treatment 2), 105 cfu (Treatment 3) and 106 cfu (Treatment 4). According to the t-test performed, it is established that L. bulgaricus imposes a significant increase in plant height and reducing chlorophyll content while insignificant in reducing leaf infection. This study widens the scope of study of yogurt bacteria on diseased paddy to find further causes of chlorophyll content in promoting the growth of paddy.
