INFLUÊNCIA DA CULTURA DO PIMENTÃO (Capsicum annuum L.) NOS ELEMENTOS AMBIENTAIS EM AMBIENTE PROTEGIDO   Marcelo Augusto de Aguiar e SilvaJoão Francisco EscobedoEmerson GalvaniSetor de Ciências Ambientais, Departamento de Recursos Naturais, Faculdade de Ciências Agronômicas, Universidade Estadual Paulista, Botucatu, SP. CP 237, CEP: 18603-970. E-mail: [email protected]   1 RESUMO              No presente trabalho foram avaliados os elementos ambientais: temperatura do solo, temperatura e umidade relativa do ar, nas condições de ambiente protegido (coberto com polietileno) e de campo, num período sem cultura (solo sem cobertura vegetal) e num outro com a cultura do pimentão, em anos diferentes, nas condições climáticas de Botucatu, SP. O híbrido de pimentão utilizado foi o Margarita, que apresenta frutos vermelhos quando maduros. A temperatura do solo foi monitorada por dois sensores eletrônicos instalados a 0,1m de profundidade, sendo um na condição de ambiente protegido e outro na condição de campo, e a temperatura e umidade do ar foram monitoradas por dois sensores eletrônicos instalados a 2m de altura (ambiente protegido e campo). O efeito do pimentão alterando o microclima de cultivo foi observado na temperatura do solo, que apresentou menores valores do índice no período com a cultura, uma vez que o dossel funcionou como uma barreira física que impediu que a radiação solar chegasse ao solo. Os valores encontrados para o índice da temperatura e umidade relativa do ar no período sem a cultura foram muito próximos aos encontrados no período com a cultura, não caracterizando o efeito do pimentão sobre essas variáveis.  UNITERMOS: Influência da cultura, temperatura do solo, temperatura e umidade do ar, pimentão.   AGUIAR E SILVA, M. A.; ESCOBEDO, J. F.; GALVANI, E.  INFLUENCE OF BELL PEPPER CROP (Capsicum annuum L.) ON GREENHOUSE ENVIRONMENTAL VARIABLES   2 ABSTRACT              The objective of this research was to evaluate the effect of bell pepper on climatic variables such as air temperature and relative humidity as well as soil temperature. The measurements were obtained under greenhouse and field environmental conditions taking into account two soil cover situations: without vegetation and with bell pepper crop (Margarida hybrid). The research was carried out in an experimental area of the Environmental Sciences Section of the Natural Resource Department, FCA/UNESP, Campus of Botucatu-SP, from June 1st to September 5th 1999 (without crop) and June 1st to September 5th 2000 (with crop). Soil temperature was monitored by two electronic sensors installed at 0,1 meter depth, inside and outside the greenhouse. Air temperature and relative humidity were monitored by two electronic sensors installed at 2m height, inside and outside the greenhouse. The effect of bell pepper on crop microclimate was evidenced by soil temperature which showed index mean values 1.04 (without crop) and 0.95 (with crop). Crop canopy acted as a physical barrier blocking solar radiation. Air temperature and relative humidity mean indexes did not present significant differences between periods with and without crop.  KEYWORDS: Soil temperature, air temperature, air relative humidity, bell pepper.

TEORES DE MICRONUTRIENTES NO DESENVOLVIMENTO DA PLANTA DE PIMENTÃO SOB FERTIRRIGAÇÃO   Francisco Fernando Noronha MarcussiDepartamento de Engenharia Rural, Faculdade de Ciências Agronômicas,Universidade Estadual Paulista, Botucatu, SP.

E-mail: [email protected]  1 RESUMO  Neste estudo, objetivou-se determinar os teores de micronutrientes (Fe, Zn, Mn, B e Cu) nos diferentes órgãos do híbrido de pimentão Elisa, sob fertirrigação em ambiente protegido, em oito épocas de coleta de planta. O experimento foi desenvolvido nas dependências do Departamento de Recursos Naturais - Ciência do Solo, FCA, Botucatu/SP. Constou o experimento de 8 tratamentos (épocas de coleta de planta – 0, 20, 40, 60, 80, 100, 120, e 140 dias após o transplante das mudas) e 4 repetições, sendo cada repetição formada por 4 plantas. Em cada etapa obteve-se os teores dos micronutrientes no fruto, folha, caule e raiz e na planta como um todo. A fertilização no ciclo estudado, 140 dias, foi feita via fertirrigação localizada. Os resultados mostram que os teores de micronutrientes encontrados na planta de pimentão seguem a seqüência: Fe>Zn>Mn>B>Cu. Nos resultados são apresentadas as tabelas com os teores de Fe, Zn, Mn, B e Cu (Tukey a 5%) em cada órgão da planta e da planta como um todo, nas diferentes épocas de avaliação e, os gráficos mostrando o comportamento dos teores de Zn, Mn, B e Cu.  UNITERMOS: Fertirrigação, concentrações de micronutrientes, Pimentão, Capsicum annuum L. e nutrição mineral.   MACUSSI, F.F.N.; VILLAS BÔAS, R.L MICRONUTRIENT CONCENTRATION IN THE BELL PEPPER PLANT DEVELOPMENT UNDER FERTIRRIGATION   2 ABSTRACT  This study aimed to determine the micronutrient contents (Fe, Zn, Mn, B and Cu) in different organs of Elisa bell pepper hybrid under fertirrigation in protected environment in eight harvesting seasons. The experiment was carried out in the Natural Resource Department – Soil Science, FCA, Botucatu. SP, and  consisted of 8 treatments (harvesting season – 0, 20, 40, 60, 80, 100 and 140 days after seedling transplant), and 4 replications, each one composed of 4 plants. In each growth period the micronutrient content in the fruit, leaf, stem, root and  plant as a whole was determined. The fertilization in the study period i.e., 140 days, was performed by local fertirrigation. The results showed that the micronutrient levels found in the bell pepper plant followed the decreasing order: Fe>Zn>Mn> B>Cu. The tables present the Fe, Zn, Mn, B and Cu (Tukey Test at 5%) contents in each plant organ and in the entire plant at different evaluation periods. The charts show the Zn, Mn, B and Cu content variation.  KEYWORDS: fertirrigation, micronutrient concentration, bell pepper, Capsicum annuum L. and mineral nutrition.

Field experiments were conducted on the research farm of IARI, New Delhi during Rabi 2016-17 and 2017-18. Three varieties of wheat (PBW-723, HD-2967 and HD-3086) were sown on three different dates for generating different weather condition during various phenological stages of crop. Results showed that during early crop growth stages soil moisture had higher value and soil temperature had lower value and with progress of crop growth stage, the moisture in the upper layer decreased and soil temperature increased significantly as compared to the bottom layers. During tillering and jointing stage, air temperature within canopy was more and relative humidity was less while during flowering and grain filling stage, air temperature within canopy was less and relative humidity was more in timely sown crop as compared to late and very late sown crop. Radiation use efficiency and relative leaf water content had significantly higher value while leaf water potential had lower value in timely sown crop followed by late and very late sown crop. Yield had higher value in HD-3086 followed by HD-2967 and PBW-723 in all weather conditions. Canopy air temperature difference had positive value in very late sown crop particularly during flowering and grain-filling stages. This reflects in the yield. Yield was more in timely sown crop as compared to late and very late sown crop.
