| ABSTRACT This study aimed to investigate the applicability of artificial neural networks (ANNs) in the prediction of evapotranspiration of sweet pepper cultivated in a greenhouse. The used data encompass the second crop cycle, from September 2013 to February 2014, constituting 135 days of daily meteorological data, referring to the following variables: temperature and relative air humidity, wind speed and solar radiation (input variables), as well as evapotranspiration (output variable), determined using data obtained by load-cell weighing lysimeter. The recorded data were divided into three sets for training, testing and validation. The ANN learning model recognized the evapotranspiration patterns with acceptable accuracy, with mean square error of 0.005,... |

| Chrisopids are economically significant predators of several agricultural pests. In Argentina, the species recorded of Chrysoperla Steinmann, 1964 are C. externa (Hagen, 1861), C. asoralis (Banks, 1915), C. argentina (González Olazo & Reguilón, 2002) and C. defreitasi (Brooks, 1994). Chrysoperla asoralis and C. argentina have been associated with citric, olive, maize and cotton crops. In the present note, we record for the first time these two species in La Plata and neighboring areas within the Buenos Aires province, in association with the sweet pepper, Capsicum annuum L. |

| ABSTRACT Farmers and the rural extension service in Planaltina, in the Federal District, an important pole of tomato and sweet pepper production in the Brazilian Midwest region, have been observing decreases in yield in protected cultivation lately. Yields are getting back to those registered in initial years of the system’s implementation in the region. Besides, prices paid to farmers dropped due to the retreat in fruit and vegetable consumption by Brazilians registered since 2015, triggering a crisis in the region. The so-called “Harvest-Expedition on Protected Cultivation” brought together Embrapa (Brazilian Agricultural Research Corporation), Emater-DF (Federal District Agency for Technical Assistance and Rural Extension) and SEAGRI-DF (State... |

| The use of fungicides to control powdery mildew in sweet pepper has been ineffective and genetic resistance is the best alternative. Resistance sources identified in Capsicum annuum L. are rare and unsatisfactory. The purpose of this work was to study the inheritance of C. annuum reaction to powdery mildew. Three homozygous powdery mildew resistant parents, HV-12, Chilli and #124 and three susceptible lines, 609, 442 and 428 were used to obtain seven F1's and respectively their generations F2: HV-12 x 609, 442 × HV-12, 428 × HV-12, Chilli × 609, #124 × 609, Chilli × HV-12 and #124 × HV-12. The powdery epidemic was natural using inoculum from highly sporulating susceptible pepper host. Powdery mildew host reaction evaluations were carried out during the... |
