Can outsourcing pest and disease control help reduce pesticide expenditure? Evidence from rice farmers

open access: yesAgribusiness, EarlyView.
Abstract Outsourcing pest and disease control (PDC) has grown rapidly worldwide, especially in developing countries. Although numerous studies have investigated various advantages of outsourcing PDC, little is known about its impact on pesticide expenditure.

Arbosana Olive Is Self-Incompatible, but Inter-Compatible with Some Other Low-Vigor Olive Cultivars

open access: yesHorticulturae
Trendy high-density olive fields are often monovarietal orchards, mostly using the cultivar Arbequina. However, Arbequina shows a strong self-incompatibility response, and its yields depend on wind cross-pollination, which is not always available.

Self fertility of pear varieties conditioned by natural self pollination (autogamy)

open access: yesInternational Journal of Horticultural Science, 2000
Authors studied the autofertility depending on natural self pollination (autogamy) in 59 pear cultivars during 4 seasons at three locations with different ecological conditions (Helvetia, Kecskemet-Kisfai, Keszthely).

The effect of sheltered load on reproduction in Solanum carolinense, a species with variable self-incompatibility [PDF]

open access: yes, 2009
In previous studies, we have investigated the strength of self-incompatibility (SI) in Solanum carolinense, a highly successful weed with a fully functional SI system that inhabits early successional and other disturbed habitats.

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

METHOD FOR OVERCOMING THE PASSION FRUIT SELF-INCOMPATIBILITY

open access: yesRevista Brasileira de Fruticultura
The methodology of self-pollination of passion fruit flowers at anthesis after stigma excision was proposed. This method was compared with self-pollination procedures at anthesis and at the stage of flower bud.

Pollination deficit in open-field tomato crops (Solanum lycopersicum L., Solanaceae) in Rio de Janeiro state, Southeast Brazil

open access: yesJournal of Pollination Ecology, 2013
More than 70% of world’s crops benefit from biotic pollination, and bees are their main pollinators. Despite the fact that some of these insects have been broadly studied, understanding the interactions between plant crops and their pollinators with a ...
