Effect of plant population on yield of maize and climbing beans grown in an intercropping system por Niringiye, C., Ssekabembe, CS, Kyamanywa, S.

“…There is therefore need to explore other appropriate mechanisms such as intecropping, that could substitute use of stalks. A field experiment was conducted at Kachwekano near Kabale town for two seasons: second rains of 1996 (1996b) and first rains of 1997 (1997a), to determine the appropriate plant population density (PPD) of maize that would maximize bean yield in an intercrop system. …”

Nitrous oxide and methane emissions from a subtropical rice–rapeseed rotation system in China: A 3-year field case study por Minghua Zhou, Bo Zhu, Bruggemann, N., Xiaoguo Wang, Xunhua Zheng, Butterbach-Bahl, Klaus

“…Fertilizer nitrogen (N) application has been shown to impact both methane (CH4) and nitrous oxide (N2O) emissions from rice-based crop systems, yet the responses of CH4 and N2O fluxes to N fertilizer applications in subtropical rice–rapeseed rotation systems are not well documented. A three-year field experiment was conducted to simultaneously measure the fluxes of CH4 and N2O from a subtropical rice–rapeseed rotation system under three N fertilization treatments (control with no N fertilizer addition [CK], optimized N fertilizer management practice in accordance with the recommended N fertilizer application rate of 150 kg N ha−1 season−1 [OP], local farmers common N fertilizer management practice with 250 kg N ha−1 season−1 [CP]) in southwestern China. …”

Pasture enclosures increase soil carbon dioxide flux rate in Semiarid Rangeland, Kenya por Oduor, C.O., Karanja, N., Onwong'a, R., Mureithi, S., Pelster, David E., Nyberg, G.

“…However, no study in East Africa and in Kenya has conducted direct measurements of GHG fluxes following the restoration of degraded communal grazing lands through the establishment of pasture enclosures. A field experiment was conducted in northwestern Kenya to measure the emission of CO2, CH4 and N2O from soil under two pasture restoration systems; grazing dominated enclosure (GDE) and contractual grazing enclosure (CGE), and in the adjacent open grazing rangeland (OGR) as control. …”

Salt-tolerant rootstock increases yield of pepper under salinity through maintenance of photosynthetic performance and sinks strength por Penella, Consuelo, Landi, Marco, Guidi, Lucia, Nebauer, Sergio G., Pellegrini, Elisa, San Bautista, Alberto, Remorini, Damiano, Nali, Cristina, López-Galarza, Salvador, Calatayud, Ángeles

“…The performance of a salt-tolerant pepper (Capsicum annuum L.) accession (A25) utilized as a rootstock was assessed in two experiments. In a first field experiment under natural salinity conditions, we observed a larger amount of marketable fruit (+75%) and lower Blossom-end Root incidence (-31%) in commercial pepper cultivar Adige (A) grafted onto A25 (A/A25) when compared with ungrafted plants. …”

Improving vine performance by modifying daily light interception patterns in vertically shoot positioned grapevines por Intrigliolo, Diego S., Abd El-Mageed, T. A., Abdelfatah, M. A., Lakso, A. N., Medrano Gil, Hipólito

“…Since vapour pressure deficit in the early afternoon is higher than early in the morning, decreasing the amount of radiation that the canopy receives in the afternoon could be used to reduce transpiration in those moments when the evaporative demand is higher. A field experiment was initiated in a north-south oriented vineyard where rainfed and deficit-irrigated vines were trained either as traditional VSP or with the canopy leant 30° towards the west (WSP), which were trained the same except for the inclination. …”
