The experiment was conducted in a protected cultivation in the Marechal Cândido Rondon, PR, Brazil. The experimental design was constituted of randomized blocks with six piggery wastewater doses (0, 25, 50, 100, 200 and 400 m³ ha-1) in four repetitions. The variables evaluated were: number of tillers, plant height, dry matter, leaf area, leaf number, potassium content, phosphorus content and crude protein in...

Biological parameters and parasitism capacity of Telenomus remus Nixon (Hymenoptera: Platygastridae) reared on natural and factitious hosts for successive generations

Factitious hosts are largely used in parasitoid production. However, changes in parasitism capacity may happen when hosts are switched. Therefore, the ability of a parasitoid species to be reared on factitious host and still keep high level of parasitism on the natural target pest after successive rearing can determine parasitoid quality and must be investigated. Thus, we evaluated Telenomus remus parasitism on Corcyra...

Effect of Silicon and Nitrogen nutrition on major pest and disease intensity in low land rice

Nutrition management is one of the most important factors for enhancing yield, but it may affect the response of rice plants to pests and diseases due, in part, to the change of microclimate under the rice plant canopy. Therefore, knowledge of the relationship of nutrition management and pests and diseases is an important component in setting up a high yield production system. The pest and disease control procedures...

Some agroforestry potential for two tree legumes in the dense rainforests of Côte d'Ivoire: Characteristics of seed germination

The Ivorian forest area has been declining because of his abuse. To reduce the negative impact of forest loss on natural resources, various reforestation projects are undertaken. The species used in these programs are usually rapidly growing exotic legumes. Unfortunately, these plants are very poorly adapted to the prevailing conditions and targets are rarely achieved. Hence, replacing them with native species should be...

Study of potential environmental risk of trace metallic elements in mine tailings: Case of Draa Lasfar functional mine in Marrakech - Morocco

Mining activity is one of the most important sources of heavy metals in the environment. In Marrakech region, functioning or abandoned mines represent a great hazard due to huge amounts of waste deposited in waste dumps and tailings often with high concentration of heavy metals pollution. In this study, the chemical forms of four heavy metals in mine tailings of Draa Lasfar in north-west of Marrakech city (Morocco) were...

Investigation of morphological indices of different rice varieties (oryza sativa) in relation to insect-pest attack under shallow and semi-deep land condition during Kharif Season

Totally 23 different rice cultivars were analyzed for pest attack and varying morphological studies from Chinsurah, West Bengal, India. The individual rice cultivars were planted in both shallow and semi-deep conditions, maintaining the two replicated yield trail (RYT) with randomized block design (RBD) pattern. It was observed that the dead heart (DH) disease caused by Scirpophaga incertulas affects mostly NDR 8027...

Delineation and geographic information system (GIS) mapping of soil nutrient status of sugarcane growing tracts of Theni district, Tamil Nadu

A global positioning system (GPS) based soil survey was conducted during September 2011 in the sugarcane dominant tracts of Theni district, Tamil Nadu to map the soil fertility status using GIS software and link with different cane yield potentials. The soil samples were taken from 400 spatially distributed locations from a depth of 0 to 30 cm and analyzed for texture, pH, EC, organic carbon, available nitrogen,...

Effect of defoliation from the bottom to the top on the yield of Brazilian soybean cultivars

Among the factors that may cause decreases in soybean yield there are the foliar diseases that despite control it can limit grain yield. The Asian soybean rust (Phakopsora pachyrhizi) is considered the most important disease of soybean in Brazil. The aim of this work was to simulate the progress of Asian rust in Brazilian soybean cultivars by removal of trifoliate leaves from the bottom to the top. The experimental...

Effect of foliar application with salicylic acid on two Iranian melons (Cucumis melo L.) under water deficit

Scarcity of water is a severe environmental constraint to crop production in arid and semi arid region. Salicylic acid (SA) plays an important role in the regulation of plant growth in response to environmental stresses. In this study, the effect of SA (0, 70 and 100 ppm) was investigated on growth and yield of two Iranian melons (Khatooni and Ghasri cultivars) under drought stress (W100%, W80% and W60%). Experimental...

Effect of N fertilization on NPK content in castor bean under saline stress

The high concentrations of salts in water, especially in semiarid regions, increase salt concentration in the soil and plant with the consequent decrease in NPK contents. Current study evaluates the influence of irrigation with water of different salinities, associated to nitrogen (N) fertilization, on NPK contents in castor bean cv. BRS Energia. An experiment was conducted for four months, in lysimeters under the ...

Deployment of indigenous wild Ganoderma lucidum for better yield on different substrates

Ganoderma lucidum is a medicinal mushroom growing on angiospermous trees that has been used in the Orient medicine for more than 2000 years. Since now studies have been almost entirely limited to laboratory scale and much more understanding on the growth morphology and mass production is necessary to develop economical large scale processes. In this study, domestication of wild isolate of G. lucidum was done, which was...
