Apomixis (asexual seed formation) is the result of a plant gaining the ability to bypass the most fundamental aspects of sexual reproduction: meiosis and fertilization. Without the need for male fertilization, the resulting seed germinates a plant that develops as a maternal clone. This dramatic shift in reproductive process has been documented in many flowering plant species, although no major...

The present study were carried out in the Department of Genetics and Plant Breeding, Faculty of Agriculture, NDUAT, Faizabad during rabi season 2014-15 and 2015-16 entitled “standardization of biofortification and hydropriming for enhance seed yield and its quality parameters in chickpea (Cicer arietinum l.)” The objective of the study was assessing the comparative performance of yield and qual...

ecological studies on range plants enhance our knowledge on the rangeland ecosystems which are useful for their planning and management.  by doing field and laboratory experiments during 2008-2009, ecological conditions were studied in the main habitats of z. atriplicoides in the rural and winter rangelands of northern khorasan province (nkp). forage quality was also studied at different phonol...

Effects of salicylic acid (SA) on seed germination, seedling growth, flowering and biochemical activities were studied out in four cowpea (Vigna unguiculata) genotypes in control environments. The results revealed that both germination and seedling growth were negatively affected by 0.02%. SA application, however did not affect the size of full expanded buds, time of 50% flowering and date of f...

Insects introduced as biological control agents of diffuse knapweed, Centaurea diffusa, primarily reduce seed production. Knapweed densities appear to be resilient to greatly reduced seed production. We have used measurements of seedling density and survival, and production of seeds by flowering diffuse knapweed plants to develop functions for a model of knapweed populations. These simulations ...

to study the effect of urea application in safflower (carthamus tinctorius) and determination of effective traits on its yield, a factorial experiment based on randomized complete block design in three replications was conducted in tabriz, iran, during 2012. studied factors were urea rate levels as 100, 150 and 200 kg/ha and urea application times 100% in sowing time, 50% sowing time + 50% stem...

The influence of different levels of phosphorus on corm and flower productivity of Gladiolus (Gladiolus grandiflorus) was studied at Faculty of Agriculture Rawalakot, Azad Jammu and Kashmir during the year 2010. Corms of similar size and weight were collected from Awan Nursery and Seed Store, Rawalpindi. Sowing was done on 25 April, 2010 with five different phosphorus levels viz. 40, 70, 100, 1...

The study was done during winter season 2020-2021 at field of College Agricultural Engineering Sciences, Duhok University, to evaluate the influence different phosphorus fertilizer P2O5 rate (0, 60, 90, 120kg ha-1 on yield and components four promising bread wheat Bura, Jehan-99, Apst-35 Apst-26. experiment Laid out in factorial experiments using randomize complete block design with three repli...

proper irrigation scheduling, i.e. timely and adequate irrigation is an important prerequisite to profitable crop production. high temperatures along with soil moisture deficits are some of the main limiting factors for canola (b. napus l.) production in dry land cropping systems. these factors negatively affect the formation of pods during the flowering stage, resulting in decrease in seed yie...

Effective detection of rice spikelet flowering is crucial to the determination optimal pollination timing for hybrid seed production. Currently, status relies on manual observation farmers, which has low efficiency and large errors. This study attempts acquire information using a hyperspectral technique machine learning in order meet needs rapidly automatically. Hyperspectral data male parents ...
