Screening melon genotypes for resistance to Meloidogyne enterolobii

Melon (Cucumis melo L.) is a cucurbitaceous of great appreciation worldwide. The intensive cultivation of melons has favored the increase of plant health problems in several producing regions. Among these problems, the root-knot nematode (Meloidogyne spp.) stands out. The development of genetically resistant cultivars is consolidated as an effective strategy for the management of these pathogens, it is then essential to...

Potential use of herbicides in different sorghum hybrids

The sorghum crop in Brazil has expanded substantially. Among the factors that interfere in sorghum yield is the interference imposed by the presence of weeds. The objective of this study was to assess the potential of different herbicide treatments applied in pre-emergence or post-emergence of sorghum in terms of selectivity and weed control. Two experiments were conducted, one for each application modality:...

Gas exchange, growth and yield of cowpea genotypes under different irrigation strategies

Water availability is a major limiting factor for cowpea bean crops, especially in semiarid regions, where it is necessary to adopt more productive and tolerant genotypes and efficient strategies for water use. Thus, an experiment was carried under field conditions in the semiarid region of Pombal city, PB, Brazil. Using a completely randomised blocks design experiment and four replications, in a factorial scheme. The...

New substrates for the cultivation of Pleurotus ostreatus using exhausted compost

Several materials have been used in the cultivation of the edible mushroom Pleurotus ostreatus. However, little is known about the reuse of the exhausted compost. This study evaluated the utilization of used substrates. Four formulations of composts were evaluated: C1 with no exhausted compost, and C2, C3 and C4 with 26, 45 and 64% of exhausted compost, respectively. Loss of organic matter, biological efficiency and...

Growth, chlorophyll index and production of common and cowpea beans using different fertilizations

Beans are a the major component in the Brazilian diet population, mainly in the northeast of Brazil, though yield is considered low due to the low technological content that is conducted in most producing regions, making it necessary for fertilizations to increase this feature. Considering the above, this study aimed to evaluate growth, chlorophyll index and the production of cowpea bean and common bean under different...

Seedling of development and tolerance of eggplant cultivars under saline stress

This study aimed to evaluate the initial growth and tolerance of eggplant cultivars under saline water irrigation. The experiment was carried out in protected environment (greenhouse) at the Federal University of Campina Grande - UFCG, located in the municipality of Pombal-PB, Brazil. The experiment was set in a completely randomized design, in a 2 × 5 factorial scheme, corresponding to two eggplant cultivars (C1...

Phenotypic profiles of different accessions of sweet potato (Ipomoea batatas L. Lam) in the coastal savanna agro-ecological zone of Ghana

Twenty accessions of sweet potato (Ipomoea batatas L. Lam) cultivated under rain-fed conditions were evaluated based on their agromorphological traits to assess diversity in yield, morphology and other key agronomic characteristics of the accessions under study. The accessions consisted of 13 local and 7 exotic breeding lines grown in the research farm of the Biotechnology and Nuclear Agriculture Research Institute...

Path analysis for yield traits in F2 generation and molecular approaches for breeding rice tolerant to drought and submergence

Drought and submergence are the two major limiting factors that reduce rice production. In this study, the relevance of yield traits through path analysis under drought and submergence conditions to improve grain yield of rice, from dry season 2014-2015 and genotypic analysis using SSR markers was evaluated, during 2015-2016. Path analysis indicated that the number of panicles/clusters had the highest and a direct...

Evaluation of the nutritional value of soaked-boiled-fermented Java plum (Syzygium cumini) seed meal for poultry

Chemical analysis, apparent metabolizable energy (MEn), and one feeding trial were conducted to evaluate the nutritional value of Java plum seeds (JPS) that had been subjected to a combination of soaking, boiling, and fermentation (SBF). Five broiler starter diets were formulated with the processed Java plum seed meal (JPSM) comprising 0, 80, 160, 240, and 320 g/kg of the diet. The JPS before and after processing...
