Does simultaneous adoption of drought-tolerant maize varieties and organic fertiliser affect productivity and welfare outcomes? evidence from rural Nigeria by Oyetunde-Usman, Z., Shee, A., Abdoulaye, T.

“…Employing nationally representative household survey data in Nigeria, this study utilises multivalued inverse probability weighted regression adjustment, entropy balancing and a multinomial endogenous switching regression model to determine the effects of the adoption of drought-tolerant maize varieties (DTMVs) and organic fertiliser on farm households' productivity, per capita total expenditure and per capita food expenditure. …”

Effects of agricultural mechanization on economies of scope in crop production in Nigeria by Takeshima, Hiroyuki, Hatzenbuehler, Patrick L., Edeh, Hyacinth O.

“…Using panel data from farm households and crop-specific production costs in Nigeria, we estimate how the adoptions of animal traction or tractors affect the economies of scope (EOS) for rice, non-rice grains, and legumes/seeds, which are the crop groups that are most widely grown with animal traction or tractors in Nigeria, with respect to other non-rice crops. The inverse-probability-weighting method is used to address the potential endogeneity of mechanization adoption and is combined with primal- and dual-models of EOS estimation. …”

The excessive (and wasteful) consumption of food by Cafiero, Carlo

“…Age, being a farmer, food insecurity, and body mass index were inversely associated with vitamin D intake (p<0.001), and socioeconomic status, total energy intake, and level of education were positively associated with vitamin D intake (p<0.001) in multiple linear regression analysis with vitamin D intake as the outcome. …”

Dual regulation of water retention and cell growth by a stressassociated protein (SAP) gene in Prunus by Lloret, Alba, Conejero, Ana, Leida, Carmen, Petri, Cesar, Gil-Muñoz, Francisco, Burgos, Lorenzo, Badenes, María L., Ríos, Gabino

“…Moreover, we established that leaf morphological alterations were concomitant with a reduced cell size and down-regulation of genes involved in cell growth, such as GROWTH-REGULATING FACTOR (GRF) 1-like, TONOPLAST INTRINSIC PROTEIN (TIP)-like, and TARGET OF RAPAMYCIN (TOR)-like. Especially, the inverse expression pattern of PpSAP1 and TOR-like in transgenic plum and peach buds suggests a role of PpSAP1 in cell expansion through the regulation of TOR pathway.…”
