Characterizing the diversity of sweetpotato through growth parameters and leaf traits: Precocity and light use efficiency as important ordination factors por Ramírez, D., Gavilan, C., Barreda, C., Condori, B., Rossel, G., Mwanga, Robert O.M., Andrade, M.I., Monneveux, P., Anglin, Noelle L., Quiróz, R., Ellis, David

“…Leaf mass per area (LMA), N and P content in leaves, light response curve parameters and carbon discrimination were assessed in potted plants at early-growing period (58 days after planting). Precocity proxies (inversely related to LMA and thermal time at maximum storage root growth) and conversion efficiency of intercepted radiation indicators (quantum yield and LUE) were important factors in the varieties ordination based on leaf traits and growth parameter scales, respectively. …”

Time course of biological nitrogen fixation, nitrogen absorption and biomass accumulation in three woody legumes por Kadiata, B.D., Mulomgoy, K., Isirima, N.O.

“…The proportion of plant N derived from absorption (soil+fertilizer) over time decreased inversely to the increase in symbiotic N2 fixation, with soil being the predominant source. …”

The effect of nitrogen on the growth and development of giant witchweed, Striga hermonthica Benth: effect on cultured germinated seedlings in host absence por Igbinnosa, I., Cardwell, K.F., Okonkwo, S.N.C.

“…Increasing concentrations ofKN03, NaN03, Ca(N03h, Mg(N03h and asparagine resulted in a significant increase in S. hermonthica shoot development. Inversely, increasing concentrations of (NH4hS04, NH4H2P04, NH4CI and urea led to increasing significant reduction of S. hermonthica shoot development. …”

Infestation and damage by Clavigralla tomentosicollis and Anoplocnemis curvipes (Hemiptera: Coreidae) in cowpea plants with modified leaf structure and pods in different positions... por Koona, P., Osisanya, E., Jackai, L.E.N., Tonye, J.

“…Seed damage decreased significantly with increasing defoliation in plants infested with C. tomentosicollis; an inverse trend was observed with A. curvipes. Temperatures within the canopy increased as the number of leaves decreased. …”

Opportunities for exploiting variations in haulm fodder traits of intermittent drought tolerant lines in a reference collection of groundnut (Arachis hypogaea L.) por Blümmel, Michael, Ratnakumar, P., Vadez, Vincent

“…Under fully irrigated conditions haulm nitrogen content and in vitro digestibility were mildly, but significantly inversely, related to pod yields with the two haulms traits accounting for 5 and 4% of the variations in pod yields. …”

Understanding nutrient imbalances in maize (Zea mays L.) using the diagnosis and recommendation integrated system (DRIS) approach in the Maize belt of Nigeria por Aliyu, K.T., Huising, J.E., Kamara, A., Jibrin, J.M., Mohammed, I.B., Nziguheba, G., Adam, A.M., Vanlauwe, Bernard

“…Results indicated that omission of N or P resulted in highly imbalanced DRIS indices respectively, and significantly lower grain yield. A strong inverse relationship between K ear leaf content with DRIS index suggests that K application negatively increases K imbalance in many situations. …”

Influence of altitude as a proxy for temperature on key Musa pests and diseases in watershed areas of Burundi and Rwanda por Nakato, Gloria Valentine, Okonya, Joshua Sikhu, Kantungeko, Deo, Ocimati, Walter, Mahuku, George, Legg, James P., Blomme, Guy

“…Information on effects of climate change on pests and pathogens of banana is required by policy makers and researchers in designing control strategies and adaptation plans. Since altitude is inversely related to temperature, this study used the occurrence of key banana pests and diseases along an altitude gradient as a proxy for the potential impact of changes in temperature associated with global warming on pests and diseases. …”
