Haploid plants are very important in various realms of research disciplines such as plant biotechnology, molecular genetics and traditional plant breeding. They provide useful information regarding recombination and genetic control of chromosomal pairing. Haploidy expedites the breeding process thereby increasing the crop yield. Researchers have been working on the haploidy approach for more th...

Topography in East Nusa Tenggara Province dominate by dryland and slope land. In the farmers develop farming system of maize as a staple crop. Dryland potential for food crop Bali reach 645,891 ha but have low fertile productivity maize. Productivity only 2.7 ton/ha. This is lower if compare with average national level result research. The objective research to get specific technology cultivati...

The present study was conducted with a view to analyzed growth and trend in area, production and yield of major crops of Khyber Pakhtunkhwa. A time series data from 1980-81 to 2011-12 (32 years) of major crops (wheat, maize, rice and sugarcane) were collected. The compound growth rate as well as trend analysis indicated that the area under wheat crop has decreased over the time due to shifting ...

Wheat (Triticum aestivum) production in the rainfed area of Pothwar Pakistan is extremely vulnerable to high temperature. The expected increase in temperature due to global warming should result in shorter crop life cycles, and thus lower biomass and grain yield. Two major factors control wheat phenological development: temperature and photoperiod. To evaluate wheat development in response to t...

In this paper, we detail our current work on a crop management system for irrigated wheat in Egypt. The goal of our work is to develop a system that will address all aspects of crop management including varietal selection, planting/harvest date selection, sowing parameters decisions, insect/disease/weed identification and remediation, and irrigation/fertilization management. The approach we tak...

In a pot culture experiment, the root length density, potassium concentration in crop, and total K uptake by wheat (Triticum aestivum var. HD 2285) at different growth stages (CRIS-Crown Root Initiation Stage, MTS-Maximum Tillering Stage, FLS-Flag Leaf Stage and DFS-Dough Formation Stage) were determined. Wheat crop was grown in 72 pots containing 4.5 kg of three types of soils, namely Alfisol,...

A supervised feature selection algorithm was applied to determine the most important features contributing to wheat grain yield. Four hundreds seventy two fields (as records) from different parts of Iran which were different in 21 characteristics (features) were selected for feature selection analysis. Selection of the wide range of features, including location, genotype, irrigation regime, fer...

Results from long-term experimental trials suggest that similar yields and lower costs are possible from organic compared with conventional field crop production, but there is little information about the relative costs and returns on commercial farms. This study examines the structure and profitability of commercial wheat production using a nationwide survey of wheat producers for 2009 that in...

Water deficit significantly limits dryland rainfed fruit production, so increasing water conservation is crucial for improving fruit productivity in arid and semiarid areas. In this study, we tested two treatments in an apple orchard: 1) PC treatment comprising black plastic mulch (BPM) (in-row) with weed control (inter-row); 2) and PGC treatment comprising BPM (in-row) combined with a summer c...
