Effect of intercropping agro- ecosystem on the population of black legume aphid, Aphis craccivora Koch, and yield of faba bean crop.

2016 | Keywords Faba bean, intercropping, yield, population dynamic, Aphis craccivora,
Effect of intercropping agro- ecosystem on the population of black legume aphid, Aphis craccivora Koch, and yield of faba bean crop.
Abstract Faba bean yield is losses due to several insect pests, such as, Aphis craccivora Koch. Field trials were conducted during two cropping seasons at Sohag- Egypt, to determine the effect of intercropping of faba bean with coriander, fenugreek or onion crops on A. craccivora population and yield of faba bean. The population of the aphids were significantly (P>0.05) lower ... Read more

Response of durum wheat and associated weeds to some weed management under various seeding rates

Response of durum wheat and associated weeds to some weed management under various seeding rates
ABSTRACT Weeds are considered as one of the biggest obstacles in wheat production. Using the proper seeding rate and applying the effective weeding program are among the factors suppressing weeds, improving wheat grain yield and its quality. This study aimed at evaluating the effects of five weed control treatments i.e. Bromoxynil (Brominal) (24% EC), Clodinafop-Propargyl (Topik) (15% WP), Brominal + ... Read more

Evaluation of some maize hybrids under nitrogen fertilization levels.

2016 | Keywords correlation coefficients, Grain yield and attributes, N-levels, Maize hybrids,
Evaluation of some maize hybrids under nitrogen fertilization levels.
Abstract Genetic selection of maize hybrids is related to using high nitrogen levels, which require to a stronger N input to accomplish their yield potential. This study aimed to investigate the response of some maize hybrids to five nitrogen fertilizer levels (0, 75, 100, 125, 150 kg N fed-1) at the Experimental and Research Center, Moshtohor Faculty of Agriculture, Benha ...

IMPROVING PRODUCTIVITY OF BREAD WHEAT GENOTYPES BY USING OF SOME GROWTHPROMOTERS
ABSTRACT Two field experiments were conducted at the Experiment and Research Center, Fac. of Agric, Moshtohor, Benha Univ., QalubiaGovernorate, Egypt during the two winter growing seasons of 2008/09 and 2009/10 to study the effect of four growth promoters treatments (malt extract yeast extract, benzyl adenine and control) as seed-soaking on growth, yield and yield components of five wheat genotypes (Giza ...

GENETIC ANALYSIS OF YIELD AND ITS COMPONENTS IN INTRA-SPECIFIC COTTON CROSSES

2003 | Keywords Heterosis, Inbreeding depressi, Inbreeding depressin, yield and its components, intra-specefic cotton crosses, Gossypium barbadense,
GENETIC ANALYSIS OF YIELD AND ITS COMPONENTS IN INTRA-SPECIFIC COTTON CROSSES
ABSTRACT This study was carried out during three successive seasons, 2000, 2001 and 2002 at the Experimental Farm of Faculty of Agriculture in Sohag, South Valley University. The main objective of this study was to estimate heterosis, inbreeding depression, potence ratio, type of gene action, genetic advance under selection and heritability in broad and narrow senses for yield and some ...
