RESUMO No cultivo de abacaxi, é comum a prática de cobertura dos frutos com jornal, a fim de evitar a escaldadura causada pela queima solar. Contudo, a escassez de material e o aumento de mão de obra têm levado à busca por alternativas de controle. Objetivou-se avaliar o uso de telas de sombreamento na produção e qualidade de abacaxi ‘Smooth Cayenne’. O delineamento experimental foi o de blocos ao caso, com cinco tratamentos (frutos cobertos com jornal e cobertura das plantas com telas de 35; 40; 50; e 80 % de sombreamento), quatro repetições e duas épocas (verão e inverno). No verão, a utilização de telas com 50 % de sombreamento determinou ganhos médios de 22 e 39 % de massa total e comercial dos frutos com coroa por planta e 22 e 40 % de produtividade total e comercial por hectare, respectivamente. O aumento gradativo da intensidade de sombreamento resultou em decréscimo dos atributos qualitativos dos frutos, em comparação à cobertura com jornal. Telas com até 50 % de sombreamento podem substituir a cobertura de frutos com jornal para evitar a escaldadura dos frutos.

ABSTRACT In pineapple cultivation, it is common to cover the fruit with newspaper, in order to avoid scalding caused by sunburn. However, the scarcity of material and the large labor force required have led to the search of control alternatives. This study aimed to evaluate the use of shading screens in the production and quality of ‘Smooth Cayenne’ pineapple. A randomized blocks experimental design was used, with five treatments (fruits covered with newspaper and plants covered with screens with 35, 40, 50 and 80 % of shading), four replicates and two seasons (summer and winter). In the summer, the use of screens with 50 % of shading provided average gains of 22 and 39 % of total and commercial mass of crowned fruits per plant and gains of 22 and 40 % of total and commercial yield per hectare, respectively. The gradual increase in shading intensity resulted in a decrease in the qualitative attributes of the fruits, when compared to covering the fruits with newspaper. Screens with up to 50 % of shading can replace newspaper when covering the fruits to avoid scalding.

Abstract IAC Netuno, a black common bean cultivar with high grain yield potential, 2968.20 kg ha-¹, upright plant architecture and Type II indeterminate growth habit, about a 90-day cycle, and 1000-seed weight of 230 grams, recommended for all common bean crop seasons in the state of São Paulo.

Abstract IAC Sintonia, new common bean cultivar, was developed to incorporate moderate resistance to the main pathogens Fusarium oxysporum and Colletotrichum lindemuthianum allied to great grain yield observed, 5,750.00 kg ha-1. IAC Sintonia has semi-upright architecture and indeterminate growth habit (Type II), cycle is around 90 days and, 1000 seed weight of 280 grams.

Atualmente, os sistemas de produção de alimentos tendem a incluir manejos sustentáveis do solo e da água. Um dos principais desafios do cultivo orgânico do feijoeiro é o manejo da adubação. Este trabalho objetivou avaliar doses de fertilizante orgânico à base de resíduos de frigorífico (1,0 t ha-1; 1,5 t ha-1; 2,0 t ha-1; e 2,5 t ha-1). O delineamento experimental foi em blocos casualizados, em esquema fatorial 4x2x2, com 16 tratamentos e 4 repetições. Foram realizadas as seguintes avaliações: massa seca de plantas; diagnose foliar; população inicial e final de plantas; número de vagens por planta, grãos por planta e grãos por vagem; massa de 100 grãos; e produtividade de grãos. Concluiu-se que os métodos e épocas de aplicação do fertilizante orgânico não influenciam os componentes de produção e produtividade do feijoeiro. A dose de 2,5 t ha-1 de fertilizante orgânico propiciou a maior produtividade do feijoeiro em 2012, porém, não expressou sua capacidade máxima de produção.

Nowadays the food production systems tend to include the sustainable management of soil and water. One of the main obstacles to the organic cultivation of common bean is the fertilization management. This study aimed to evaluate doses of organic fertilizer containing slaughterhouse residues (1.0 t ha-1, 1.5 t ha-1, 2.0 t ha-1 and 2.5 t ha-1). The experimental design was randomized blocks in a 4x2x2 factorial scheme, with 16 treatments and 4 replications. Plant dry weight; foliar diagnose; initial and final plant population; number of pods per plant, grains per plant and grains per pod; 1000-grain weight; and grain yield were evaluated. It was concluded that the methods and time of organic fertilizer application do not affect the production components and yield in common bean. The dose of 2.5 t ha-1 of organic fertilizer provided the highest common bean yield in 2012, but it did not express its maximum production capacity.

The Instituto Agronômico de Campinas - IAC registered the carioca type common bean cultivar IAC Milênio. The cultivar has a mean yield of 2831 kg ha-1, high grain quality with tolerance to darkening, and resistance to Fusarium oxysporum and physiological races 81, 89, and 95 of the anthracnose pathogen (Colletotrichum lindemuthianum).

In the state of São Paulo, common bean is an important crop and the Agronomic Institute (Instituto Agronômico - IAC) registered the "carioca" (beige with brown stripes) bean cultivar IAC Imperador in the MAPA/RNC, exhibiting mean yield of 2,266 kg/ha in the 17 environments evaluated, a 75-day cycle, resistance to soil diseases and high quality seeds.

The MAPA/RNC registered the cultivar IAC Formoso with carioca grain of the Instituto Agronômico IAC, in view of the high mean yield in 24 environments (approximately 2816 kg ha-1), resistance to anthracnose (Colletotrichum lindemuthianum) and Fusarium solani, high grain quality and a cycle of 85 days from emergence to harvest.
