| ABSTRACT Response of pumpkin species including Cucurbita pepo convar. Pepo, Cucurbita moschata Duch, Cucurbita pepo, Cucurbita maxima, and Lagenaria vulgaris to bentazon, trifluralin, metribuzin, and oxyfluorfen was evaluated in Outdoor pot experiments in 2014 and 2015. Different postemergence doses (bentazon and oxyfluorfen) and preplant incorporated (metribuzin and trifluralin) herbicides were evaluted on pumpkin species at various growth stages. Results showed that the sensitivity of pumpkins species to applied herbicide varied greatly among tested species. On overall, dry weights of Cucurbita spp. were reduced by 12.50%, 48.60%, 23%, and 73.13% when pumpkin was treated with trifluralin, metribuzin, bentazon and oxyfluorfen, respectively. Pumpkin crops... |

| Gulupa, Passiflora edulis Sims (Passifloraceae), is an important fruit due to its organoleptic and nutritional characteristics and its demand in the international market; however, very few studies have been conducted for studying its Ecophysiology. Until now, this crop has spread throughout the country through empirical knowledge without data that indicate the zones that are more suitable for its cultivation. For this reason, gas exchange, chlorophyll fluorescence (photosystem II operating efficiency and maximum quantum efficiency of photosystem II photochemistry) and leaf water potential were measured in three different locations of Cundinamarca department (Chia [2610 m a.s.l., 14 °C], Granada [2230 m a.s.l., 15 °C] and Tena [2090 m a.s.l., 17 °C]), whose... |

| During the last two decades, various non-governmental organizations have strongly encouraged Bolivian farmers in the Altiplano region near Lake Titicaca to resume the ancestral agricultural practice of constructing raised fields. In addition to improved drainage and possibilities this practice affords for sub-irrigation, advocated benefits of this system traditionally include frost mitigation and high crop yields. Until recently, reliable data to assess the extent of these benefits were unfortunately lacking. In this context, field experiments on raised fields were designed and carried out at two locations in the Bolivian Altiplano to obtain reliable potato yield and temperature data. Observed yields ranged from 2.73 to 10.80 t ha-1 at the first site,... |
