Decision support systems can help improving nutrient management in agricultural and forest ecosystems. We suggest that the practical components of nutrient management are 1) Diagnosis, 2) Prediction, 3) Economic analysis, and 4) Recommendations. Nutrient management and agronomic information for perennial crops such as peach palm (Bactris gasipaes Kunth) revealed important differences from annua...

Micropropagation of woody plants and fruit crops constitutes a major success in the commercial application of in vitro cultures. An important aspect to be considered when deriving perennial plants from micropropagation is the maintenance of genetic integrity with regard to the mother plant. In this regard, somaclonal variation has been reported at different levels (morphological, cytological, c...

Cropping sequences integrating perennial forages and annual crops can generate multidimensional agroeconomic environmental benefits. A 4-yr cropping sequence study was conducted from 2013 to 2016 evaluate the relative merits of various sequences. Three forage seed (creeping red fescue [Festuca rubra L.], alsike clover [Trifolium hybridum pratense L.]) four food (wheat [Triticum aestivum canola ...

Increased production of biomass crops in North America will require new agricultural land, intensify the cultivation of land already under production and introduce new types of biomass crops. Assessing the potential biodiversity impacts of novel agricultural systems is fundamental to the maintenance of biodiversity in agricultural landscapes, yet the consequences of expanded biomass production ...

Perennial crops have numerous ecological and agronomic advantages over their annual counterparts. We estimate discrete choice models to evaluate farmers' preferences for perennial attributes of pigeon pea intercropped with maize in central and southern Malawi. Pigeon pea is a nitrogen-fixing leguminous crop, which has the potential to ameliorate soil fertility problems related to continuous mai...

Planting the perennial biomass crop Miscanthus in the UK could offset 2-13 Mt oil eq. yr-1, contributing up to 10% of current energy use. Policymakers need assurance that upscaling Miscanthus production can be performed sustainably without negatively impacting essential food production or the wider environment. This study reviews a large body of Miscanthus relevant literature into concise summa...

Public forests in central Leyte, Philippines provide an important source of annual food crops, perennial cash crops, and rattan and timber to lowland farmers. Household economic dependence upon and uses made of forest resources are associated with relative access to lowland-based activities, especially production of irrigated rice. Households unable to procure sufficient food staples through on...

ABSTRACT- Efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. This research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (WP) with different water management scenarios at farm level at ...
