Using adequate sample size in experimental units improves the efficiency of the research. In the agricultural year of 2004/2005, an experiment was conducted in Santa Maria, Rio Grande do Sul State, Brazil, with the objective of estimating sample size for the following traits: ear length, ear and cob diameter, ear weight, weight of grains per ear, cob weight and the weight of 100 grains, number ...

The experiment was conducted in CRF Department of Agronomy during summer season 2022 on Maize crop. aim to study the effect soil application zinc and foliar boron growth yield maize. Treatments consisted 3 levels Zinc (5,10 15 kg/ha) Boron (0.5, 1 1.5%) as spray a control. laid out Randomized Block Design (RBD) with Ten treatments each replicated thrice. Application kg 1.5% recorded highest Pla...

¹⁴C labeling experiments performed with kernel cultures showed that developing maize endosperm is more efficient than other non-photosynthetic tissues such as sunflower and maize embryos at converting maternally supplied substrates into biomass. To characterize the metabolic fluxes in endosperm, maize kernels were labeled to isotopic steady state using ¹³C-labeled glucose. The resultant labelin...

MON 810 maize was developed against Ostrinia nubilalis and is suggested to indirectly decrease Fusarium spp. infestation in maize ears. To evaluate this effect, co-occurrence of insect and fungal pests on MON 810 maize was studied. During 2009, exceptionally high maize ear infestation occurred in Julianna-major (Hungary). From investigation of some thousands of maize ears, the majority of the l...

A field experiment was conducted to evaluate the integrated effect of weed control practices on the weed control efficiency, growth and yield of autumn planted maize (Zea mays L.) under agroecological conditions of Faisalabad. Treatments comprised manual hoeing and earthing up alone and in combination with metolachlor + atrazine @1110+740 g a.i.ha; manual hoeing + earthing up, metolachlor + atr...

Strontium (Sr)-isotope values on bone from deer mice pairs from 12 field sites in the Chaco Canyon area, New Mexico, were compared with isotope values of synthetic soil waters from the same fields. The data indicate that mice obtain Sr from near-surface sources and that soil samples collected at depths ranging from 25 to 95 cm contain Sr that is more accessible to the deep roots of maize; thus,...

The first steps toward maize (Zea mays subspecies mays) domestication occurred in the Balsas region of Mexico by ∼9,000 calendar years B.P. (cal B.P.), but it remains unclear when maize was productive enough to be a staple grain in the Americas. Molecular and microbotanical data provide a partial picture of the timing and nature of morphological change, with genetic data indicating that alleles...

Maize is more likely to have weed infestations due its steady early growth rate and extensive row spacing, which favor development even before crop emergence. As a result, there prevails strong correlation between density maize yield. An experiment was conducted at the Gauradaha Agriculture Campus, Jhapa, in spring of 2022 assess effect various control methods on The had three replications eigh...
