Drought is the main constraint to maize production in Mediterranean area. This first report of breeding temperate populations from Algerian desert. The objective this study was evaluate response selection for reduced anthesis-silking interval (ASI) under drought and control conditions. Three cycles ASI were carried out four conditions, program evaluated both Selection more efficient than partic...

Global climate change is predicted to increase temperatures, alter geographical patterns of rainfall and increase the frequency of extreme climatic events. Such changes are likely to alter the timing and magnitude of drought stresses experienced by crops. This study used new developments in the classification of crop water stress to first characterize the typology and frequency of drought-stres...

A field experiment was carried out in the fields of college agricultural engineering sciences, university Baghdad during fall season 2021, order to find which cultivated genotypes maize are efficient under nitrogen fertilization. The applied according a RCBD (split plot design with three replications). (Baghdad, 5018 and Sarah) supplying levels fertilizer, N1 (100 kg/ha), N2 (200 kg/ha) N3 (300...

Understanding the variability, heritability, and genetic advance in maize is crucial for efficient plant breeding improvement programmes. The present investigation was conducted to evaluate various parameters related assessment of variability nature associations among traits affecting grain yield 80 genotypes (Zea mays L.) at Research Farm, Department Genetics & Plant Breeding, College Agri...

The experiment was conducted at Khairahani-5, Chitwan, Nepal from 28th February to 20th June 2021. Twenty single cross maize hybrids were evaluated for quantitative and qualitative traits. in a randomized complete block design (RCBD) with three replications. Data recorded on flowering traits, physiological disease agro-morphological yield contributing Analysis of variance showed significant dif...

Dehydration of maize grains in the field can reduce costs associated with drying after harvest. A delayed harvest approach physiological maturity, which plants stand to allow stems dry, has been widely adopted production. However, it remains unclear how harvesting at different time points during dehydration stage may affect grain yield and quality. In present study, experiments were conducted N...

The present investigation was carried out to assess genetic variability parameters, correlation coefficient analysis, path analysis in 21 maize genotypes for 15 quantitative traits viz Days 50% tasseling, silking, anthesis – silking interval, 75% maturity, Plant height (cm), Ear Cob length girth weight (g), Number of grain rows per cob, grains row, 100 Biological yield plant Harvest index (%), ...

In spite of all the efforts on deciphering such spinning process of spiders, the underlying mechanism currently is yet to be fully revealed. In this research, we designed a novel approach to quantitatively estimate the overall concentration change of spider silk along the progression of liquid-to-solid silk transition from the gland silk. As a prior characterization, we first studied the influe...

Heat stress (HS) during grain filling is an extreme environmental factor and affects plant growth development. Foliar application of exogenous brassinolide (BR) effective practice to relieve HS injuries, but the influence on accumulation remobilization biomass nitrogen still unclear. In present study, effect foliar BR at silking stage in fresh waxy maize under ambient (28/20 °C) high (35/27 tem...

Corn (Zea mays L.) nitrogen (N) strategies that account for fertilizer timing and source may differentially affect soil bacterial communities require further validation when preceded by cover crops (CC). Field studies were conducted (2014–2016) evaluating the effects of daikon radish [Raphanus sativus (L.)], forage oat [Avena sativa no CC combined with multiple N management on alpha diversity m...
