Abstract

Trees outside Forest (TOF) are trees, shrubs, bushes including palms that are found in the Food and Agriculture Organization (FAO) other land classification that can be agricultural, urban, or non-agricultural/urban. TOF provide various services and functions that are neither well documented nor given enough attention, hence the need to identify and assess them in agriculture and urban areas outside Mt. Makiling. A SPOT satellite image (2010) covering the Cambantoc, Molawin-Dampalit, and Tigbi subwatersheds of Mt. Makiling was used in the supervised classification of forests, lakes, agriculture, and urban areas. Areas that qualify as other lands were extracted using the classified land types as guides in GIS vector format. Using Google Earth imagery, other lands were digitized and assessed following the FAO decision tree algorithm for TOF and field checking was conducted to validate the tree height in the TOF criteria. Based on the GIS and field assessment, Tigbi and Molawin-Dampalit were found to have TOF on urban land that are mostly fruit trees cultivated for food, landscaping while Cambantoc has TOF on agricultural land and TOF on non-agricultural/urban that are used as farm windbreaks. Findings suggested that TOF contributed to the tree canopy cover in Makiling subwatersheds. Assessment of TOF can be used to account for the ecosystem services it provides which complement those that come from forests and other wooded lands. FAO also recognizes the importance of TOF for local and national food security. TOF, especially fruit trees, are important source of food products for the people.

Abstract

Water is the most precious commodity that human being wanted, nowadays water is depleting due to several human interventions. In Kerala state, even though high rainfall is received, still water scarcity is faced during summer and soil erosion is higher. This watershed area is prone to water scarcity during the summer season and stream network become dry during that period. This clearly indicates that human interventions and unscientific agricultural activities may be the result. In this, study GIS and RS technologies are used to find and map the Soil and water conservation priority zones, also several action Plans where proposed. SOI Topo sheet were used to digitize the contours and DEM was created using that with ArcGIS 10.2.2 software. LULC maps were digitized from satellite image and using other parameters and suitable weight values, the weighted overlay was done to find out the Priority Zones. Cadastral Plot boundaries were overlaid for plot-wise priority zones and several conservation methods like gully plugin, check dams, vegetation bund etc. were proposed.

Abstract

Maize is produced in diverse environmental conditions in Nepal. National Maize Research Program regularly tests maize genotypes for their grain yield stability in highly diverse environments. The objective of this paper is to estimate grain yield stability of quality protein maize genotypes across different environments. Two quality protein maize genotypes namely Poshilo Makai-1 and S99TLYQ-HG-B along with Farmer’s variety were tested at nine different locations of Nepal in four consecutive years before 2013 under farmer’s fields. Alpha-lattice design with two replications was used. The results of these studies revealed that S99TLYQ-HG-B was more stable followed by Poshilo Makai-1 as compare to Farmer’s variety. The overall higher mean grain yield and regression coefficient (b) near to unity showed that S99TLYQ-HG-B is the most adaptive genotype across the tested environments. However, more than unity regression coefficient (b) indicates that Poshilo Makai-1 could be the recommended variety for better environments under farmers’ management.

Abstract

This case demonstrates the potential of addressing small scale fisheries management through participatory action research (PAR) in one of the CRP 1.3/AAS sites in the Philippines. Following the iterative process of PAR, a series of focus group discussions (FGDs) to reflect on the issues and concerns of small scale fishermen (SSF) in Barangay Binitinan, Balingasag, Misamis Oriental, Philippines was carried out from February to May, 2014. This was followed by the conduct of consultative workshop among stakeholders in SSF in June 2014, the main objective of which was to develop a collective action plan for the management of said resource. The FGDs employed facilitated iteration and reflection of issues affecting various groups of small scale fishing community, while the Consultative Workshop among stakeholders used the appreciation-influence-control model of participatory stakeholder engagement (Ratner 2011).Consequently, various stakeholders of small scale fisheries begin to understand, appreciate and take actions together. A feeling of trust and confidence among them begin to develop which enabled them to craft a collective action plan on sustainable management and governance of municipal waters and fisheries resources. Aside from these outcomes, these processes led to the admission of “sahid” (beach seine) operators that they are indeed using illegal gear, that their gear would be replaced by the legal one by the Bureau of Fisheries and Aquatic Resources (BFAR), that the Law Enforcers would implement the Law and the small scale fishermen would abide the rules and would be apprehended by Law Enforcers once they violate the rules and the LGUs asking stakeholders to feedback the amendments necessary to make municipal ordinances well fitted to them. Another major outcome of these processes was the identification of research topics which the stakeholders identified to be necessary so that science-based productivity and governance decisions can be put in place. All of these activities fall within the PAR processes.

Abstract

The behavior of the farmers to using the fertilizer could be influenced by some factors. The factors such as social environment, culture, agriculture differentiate the way of using intensity the fertilizer. That behavior can also be different to what fertilizer the farmers use. The study aims to identify and analyze the behavior of farmers in using intensity of the liquid fertilizer products. The research was conducted by using a survey approach through interviews and questions (questionnaire) to 100 respondents of onion farmers in Brebes District Central Java on April until May 2015. Factors affecting the using intensity were analyzed by using multiple linear regression analysis. As the result shows in this study show that the using intensity of the liquid fertilizer is influenced by the income, the experience in planting the onions, how large the land, the productivity of the onion, the cultivating season, the recommendations from other farmers, field trials, and recommendations from the fertilizer store. The implication of the study is the farmers behavior to using the fertilizer is not only influenced of rational factors but also influenced by psychosocial factors. Government efforts to educate farmers about the benefits and risks to using liquid fertilizer need involves both aspects.

Abstract

The present study was carried out at the Agriculture research field, Patuakhali Science And Technology University(PSTU), Patuakhali, from March, 2015 to April, 2016 to explore the domestication potential and to evaluate the rooting performance of Flacourtia indica (katabohori), a wild fruit species in Bangladesh, through clonal propagation by stem cutting under 3 different doses of rooting hormone IBA (Indole Buetaric Acid) and planted in the perforated plastic tray filled with coarse sand and gravel placed in the non-mist propagator. The experiment was laid out following a Randomized Complete Block Design (RCBD) with 4 treatments and 4 replications (blocks). The treatments were T0= control, T1 = 0.2% IBA, T2 = 0.4% IBA, T3 = 0.8% IBA. The rooting ability of cuttings was significantly influenced by the application of IBA. The results showed that the highest rooting percentage (100) and maximum root number (8) of Flacourtia indica stem cuttings were obtained from the cuttings treated with 0.4% IBA followed by 0.2% IBA where as the longest root length (8.998 cm) was recorded with 0.2% IBA followed by 0.4% IBA. Survival percentage of the cutlings (the rooted cuttings) after 3 months of transferring them into poly bags was also significantly enhanced by exogenous rooting hormone (IBA) application. The highest survival percentage (84.5 %) was for the cuttings treated with 0.4% IBA followed by 0.2% IBA (71%). The similar trend was also observed for average cutling height and number of leaf. Findings of the present study reveal that the plant species is highly amenable for clonal propagation by stem cuttings using low-cost non-mist propagator. Considering both rooting percentage and root number, 0.4% IBA treatment of stem cuttings may be recommended for mass production of quality planting stocks for the domestication of the species in homestead agroforestry or in fruit orchards to provide edible fruit to rural poor people of natural disaster vulnerable Bangladesh.

Abstract

Many researchhavefound thatthe use of zero energy coolchamber (ZECC) extend the shelf life of stored fruits and vegetables. There is a lack of study conducted in Indonesia about the use of ZECC to keep mangos after harvesting though. The present study, therefore, was aimed to understand the quality and storability of stored mangos in ZECC. Three different storage containers, a ZECC, ambient, and refrigerator with different average RH and temperature, were used to place selected ripe mangos (Mangifera indica L) that were manually harvested from farmers’ field nearby. The ZECC was set up at the residential complex for lecturer of Hasanuddin University as the experiment site. Results showed that mangos inside ZECC were acceptable until eleven days of storage after considering both quality and sensory evaluation. The result suggests that ZECC can maintain mango’s quality and extend its shelf life, which reveals that ZECC seems promisingfor commercial application

Abstract

The trend of rice productivity and its stability in Badung Regency are presented in this study. The area is a tourism-based economy without leaving the role of rice production to feed the people.  Time series data were collected from five sub districts covering 53 villages during 2008-2016 due to the completeness of the data. Variability of the data was observed from the coefficient of variance (C.V.) to decide rice productivity stability. This study also observed correlation between rainfall and rice productivity in the area. Result of the study shows that rice productivity trend in Badung Regency tend to decline during nine years of observation especially in 2014-2016. Three sub-districts had stable condition, while two sub-districts in tourism area contributed to the decline of this matter. Analysis using bi-plot revealed that there is no significant correlation between rainfall in sub-district and rice productivity, implying that water is available throughout the year.  In terms of stability, majority of villages (69.81%) had stable condition of rice productivity ranging from middle and high category. Other 30.19% villages were categorized as unstable ranging from low to high productivity. This condition showed that Badung Regency were able to maintain stability of rice productivity during nine years of observation. Implication of this study is to pay more attention to two sub districts in tourism area to improve their rice productivity such as implementation of good agricultural practices.

Abstract

The study was conducted to determine the effect of weed management level on the abundance of insect natural enemies in cabbage fields. Two levels of weed management were applied in the field, namely with and without herbicide application in two growers’ cabbage fields in Malino, South Sulawesi, Indonesia. Results demonstrated that insect natural enemies were more abundant in the field without herbicide application than those in the field with herbicide application. Five species of predatory insect species were collected from both fields, anmely Solenopsis sp., Ophionea sp., Euborellia sp., Cicindella sp., and Paederus fuscipes. The herbicide and its surroundings were kept weed-free during the growing season. Four most abundant weed species were found in the field without herbicide treatment including Nasturtium indicum (Brassicaceae), Galinsoga parviflora (Asteraceae), Ageratum conyzoides (Asteraceae) and Cleome rutidospema (Capparidaceae).

Abstract

Pest control by using chemical pesticides continuously can harm the environment. Therefore it is necessary to look for environmentally friendly technologies, one of which is the use of entomopathogenic fungi such as Metarhizium anisopliae. The alternative media should be easy to obtain and has a good shelf life so the growth of M. anisopliae   should be optimum. This research aimed to obtain alternative media that provide the best growth and development at each different shelf-life. The research method used was an experimental method using a Completely Randomized Design (CRD) Factorial and it was repeated 4 times. The media factors were from PDA, bran, green beans, and maize. The shelf-life factors were at 21 and 42 days old (d-old). The diameter on maize media gave the highest diameter value of 8.57 cm at 42 d-old. Green bean media gave the best spore density results of 2.08×107. Whereas the germination capacity of the media ranged from 63.94% to 94.23%. Germination showed no significant difference at 21 and 42 d-old. Therefore, green beans and maize media were effectively used for propagation of M. anisopliae   as a substitute for synthetic media.
