title: A mechanistic study of plant and microbial controls over R* for nitrogen in an annual grassland

description: Differences in species’ abilities to capture resources can drive competitive hierarchies, successional dynamics, community diversity, and invasions. To investigate mechanisms of resource competition within a nitrogen (N) limited California grassland community, we established a manipulative experiment using an R* framework. R* theory holds that better competitors within a N limited community should better depress available N in monoculture plots and obtain higher abundance in mixture plots. We asked whether (1) plant uptake or (2) plant species influences on microbial dynamics were the primary drivers of available soil N levels in this system where N structures plant communities. To disentangle the relative roles of plant uptake and microbially-mediated processes in resource competition, we quantified soil N dynamics as well as N pools in plant and microbial biomass in monoculture plots of 11 native or exotic annual grassland plants over one growing season. We found a negative correlation between plant N content and soil dissolved inorganic nitrogen (DIN, our measure of R*), suggesting that plant uptake drives R*. In contrast we found no relationship between microbial biomass N or potential net N mineralization and DIN. We conclude that while plant-microbial interactions may have altered the overall quantity of N that plants take up, the relationship between species’ abundance and available N in monoculture was largely driven by plant N uptake in this first year of growth. We speculate that litter-mediated interactions between plants and microbes may play a larger role over longer timescales as they do in perennial communities.

title: Household and farm attributes affecting adoption of smallholder timber management practices by tree growers in Gunungkidul region, Indonesia

description: This dataset was moved to: https://doi.org/10.34725/DVN/25244Farm household characteristics determine the success of programs promoting agroforestry systems and practices. This paper reports household and farm factors affecting the adoption of timber management practices by smallholders in the Gunungkidul region, Central Java, Indonesia. The research used three logistic regression analysis models - based on each household and farm characteristic, and a composite of both together - to identify the key factors influencing farmers' adoption and management decisions, and their relative importance. A sample of 152 farmers who managed their trees primarily for timber production was compared to a sample of 115 farmers with similar socio-economic characteristics who did not. The household condition and composite models identified both on-farm and off-farm gross incomes as significant factors affecting farmers' decisions to manage timber trees. The models confirmed that farmers with larger farms, and with higher on- and off-farm incomes, were more likely to manage their trees for timber production. These results have implications for extension programs that promote adoption of commercial timber management by smallholders in the case study and similar regions.

title: Intensifying Vegetable Production in Smallholder Agroforestry Systems in West Java

description: This dataset was moved to: https://doi.org/10.34725/DVN/25258Most smallholder farmers in Indonesia cultivate both annual and perennial crops on farms of limited size, frequently 1 ha or less. Traditionally, these systems evolved to produce agricultural and tree products for home consumption, with the surplus being sold locally. The development of infrastructure and market economies has opened commercial opportunities for smallholder farmers. However, many smallholders still face challenges related to crop production and marketing: landholdings do not reflect economies of scale; suboptimal management practices produce commodities that do not meet market specifications; and farmers have limited understanding of market information and marketing channels. Additionally, farmers lack access to professional assistance that could enable them to enhance their production and marketing capacity. Working with communities in West Java, the authors implemented a number of studies to identify how vegetable production could be intensified in smallholder agroforestry systems where additional land for agricultural expansion did not exist. Baseline studies and rapid market appraisal were conducted to identify existing conditions and possible opportunities. Focus group discussions were held to identify smallholdersÂ and tradersÂ interest in expanding smallholder vegetable production and marketing. Understory vegetable production trials were con ducted under three light intensity levels representative of common agroforestry systems. A cross-visit was held to provide exposure and intensive capacity building to smallholders regarding market-oriented production of select vegetable commodities. A consumer preference study was implemented to inform smallholders and traders regarding market prospects. Findings indicate that opportunities exist for smallholders to intensify production and marketing of vegetables in their existing agroforestry systems. However, to take full advantage of those opportunities, smallholder farmers would require technical, marketing, and material assistance.

title: Replication data for: The "model farmer" extension approach revisited: Are expert farmers effective innovators and disseminators?

description: This dataset was moved to: https://doi.org/10.34725/DVN/25729How farmers can better access knowledge and technology for improving agricultural productivity is a key challenge, particularly given the growing complexity of agriculture and the decline of publicly funded extension systems. Extension programmes often make use of farmer to farmer extension and choose âmodel farmersâ, also called âmasterâ, âleadâ or âexpertâ farmers, to host demonstrations and train their fellow farmers on improved agricultural practices and innovations. Chosen on the basis of their expertise, model farmers are also assumed to be effective innovators and disseminators, but are they? This study sought to answer this question by examining a sample of 126 adopters of fast-growing leguminous fodder shrubs for feeding dairy cows and goats in Kenya. Criteria were established to rate farmers on their expertise as farmers, disseminators and innovators. Farmers were interviewed, indices were drawn up, and farmers were rated on the three categories. Forty-eight farmers were found to be expert farmers, 46 were expert innovators and 44 were expert disseminators. Forty-eight did not fit into any category. There were no significant differences between disseminators and non-disseminators with respect to age, gender and level of education. Nor were there differences between innovators and non-innovators. These finding are encouraging, as they suggest that there are no important barriers related to these variables preventing farmers from becoming innovators or disseminators. In contrast, expert farmers did tend to be wealthier and have larger land holdings than non-experts. There was some overlap among the expert farmers, innovators and disseminators, with 17 farmers being designated as members of all three categories. A log-linear regression model analysis revealed that farming and dissemination expertise are positively associated, as are innovation and di ssemination expertise. However, farming expertise and innovation expertise are not associated. Moreover, 19 (40%) of 48 expert farmers were not effective disseminators. This finding suggests that extension programmes that choose farmer trainers on the basis of their farming expertise and their dissemination skills will promote dissemination more effectively than those that choose trainers only on the basis of their farming expertise.

title: Replication data for: Effect of organic fertilizer on the growth and fruit yield of six paprika (Capsicum annum L.) cultivars in Malawi

description: This dataset was moved to: https://doi.org/10.34725/DVN/25747The production of paprika (Capsicum annum L.) under small-scale farm conditions in southern Africa is constrained by low soil fertility and lack of appropriate cultivars. The objective of this study was to determine the growth responses and fruit yields of six cultivars of paprika to organic and inorganic nutrient sources. The study was conducted in 2007 and 2008 at Chitedze Agricultural Research Station in Malawi. A combination of six paprika cultivars and four nutrient sources, namely (1) organic input from Gliricidia, (Gliricidia sepium) biomass, (2) inorganic fertilizer, (3) integrated nutrient input (Gliricidia biomass + inorganic fertilizer), and (4) control (no nutrient input) were compared. Each combination was replicated five times. A split-plot design was used where nutrient sources formed the main plot and cultivars the sub-plots. Plant height differed due to nutrient source in 2007 and 2008, while differences due to cultivar were minor.

title: Long-term record of Hudson River water temperature

description: This data set contains monthly mean water temperatures for the Hudson River 1908-2007. The measurements were taken at Poughkeepsie NY. This is one of the longest river temperature data sets on record. The majority of the data are sourced from the Poughkeepsie Water Treatment Facility in Poughkeepsie NY. We averaged daily water temperature values to monthly values and added value by filling gaps within the Poughkeepsie Water Treatment Facility data set using USGS data. We do not own the original daily values and do not provide them here. The original daily water temperature values are in the public domain and should be sought from their source (see methods description). The data provided here are described in detail by: Seekell DA, Pace ML (2011) Climate change drives warming in the Hudson River Estuary, New York (USA).

title: Replication data for: Productivity of Acacia angustissima accessions at two sites in the subtropics

description: This dataset was moved to: https://doi.org/10.34725/DVN/25749Low leaf biomass yields coupled with small land sizes are some of the major constraints faced by smallholder farmers that grow protein-rich fodder trees and shrubs. Given these challenges, availability of highly productive seed sources would be important to enable farmers to produce leaf fodder in sufficient quantities. 14 accessions of Acacia angustissima were evaluated for leaf, wood and total biomass production at two subtropical sites with uni-modal rainfall in Zimbabwe, with the objective of identifying high leaf biomass yielding accessions. There were up to fourfold difference in biomass yield between the accessions. Leaf dry matter yield ranged from 1.65 to 8.81 Mg ha-1 and 3.7 to 12.4 Mg ha-1for wood biomass at the higher altitude site (1530 m a.s.l.) but were much lower at 1272 m a.s.l. where they ranged between 0.37 and 4.88 Mg ha-1 for leaf and 0.4 and 7.2 Mg ha-1 for wood. The most productive accessions for leaf biomass were 16231 and 18579 at the higher altitude site, while 18586 and 18501 had the highest yields at the lower altitude. Although no one accession was consistently high yielding across the two sites, the least productive accessions were consistently poor at both sites. The advantage of using selected superior accessions over the unselect bulk seed was up to 85%. These findings underscore the need to promote the use of only high yielding accessions rather than unselect bulk seed. This study identified new, more productive accessions of A. angustissima that potentially widens the genetic base of the germplasm assembled in Zimbabwe.

title: Replication data for: Can Integration of Legume Trees Increase Yield Stability in Rainfed Maize Cropping Systems in Southern Africa?

description: This dataset was moved to: https://doi.org/10.34725/DVN/25746Growing maize (Zea mays) in association with legume tree in agroforestry arrangements has been shown to increase yields in many parts of sub-Saharan Africa (SSA). However, the stability of crop yields has not been critically analyzed in the various cropping systems that integrate leguminous trees. The objective of this analysis was to compare yield stability in improved cropping systems, namely maize-Gliricidia (Gliricidia sepium) intercropping and fertilized monoculture maize, with the de facto practice of resource-poor farmers who grow maize continuously without any external input. Yield stability was determined for three long-term field trials (12-13 consecutive years) conducted at Makoka Research Station in southern Malawi and Msekera Research Station in eastern Zambia. At Makoka, the most stable yield was recorded in maize-Gliricidia intercrops. Average yield was highest in maize-Gliricidia intercropping amended with 50% of the recommended N and P fertilizer, and this was comparable with yield recorded in monoculture maize that received inorganic fertilizer. On the two sites at Msekera, the highest yield was recorded in fertilized monoculture maize followed by maize-Gliricidia intercrops. However, yields were more stable in maize-Gliricidia intercropping compared to fertilized maize on both sites at Msekera. It is concluded that maize yields remain more stable in maize-Gliricidia intercropping than in fertilized maize monoculture in the longterm although average yields may be higher with full fertilization.
