in order to study the efficiency of dual-purpose herbicides at different stages of wheat (triticum aestivum), an experiment was conducted at shoushtar in 2012. the experiment was factorial with randomized complete block design arrangement of factors and four replicates. factors were dual-purpose herbicide including apyros (sulfosulfuron), total (metsulfuron methyl+sulfosulfuron), chevalier (iod...

Metre-resolution airborne multispectral images have been used to estimate crop biomass in rice (Orysa sativa L.). Images were acquired at four stages of crop development; mid-tillering, flowering, panicle initiation and immediately prior to harvest. The imaging system, flown in a light aircraft, comprised four CCD video cameras; recording in the infrared, red, green and blue wavebands. Normaliz...

Drought is the most limiting factor for production in semi-arid ecosystem of Gujarat. Under changed climate scenario due to variability rain fall pattern problem drought aggravated. In order investigate effect foliar spray different chemicals and PGRs o no durum wheat under conserved moisture condition at Agricultural Research Station, AAU, Dhandhuka , Bhal tract Gujarat rabi season cultivation...

This research was conducted to evaluate the trend of cadmium accumulation in wheat tissue and cultivated soil affected conventional cropping systems and different growth stage via split plot experiment based on randomized complete block design with three replications during 2014-2015 seasonal year. The main factor included two cropping systems (wheat-rice, fallow-wheat) and growth stage at thre...

Effect of various NaCl treatments (0, 50, 100, 200, and 300 mM) at different growth and development stages (tillering, boot swellen, flowering and anthesis) in two wheat cultivars (Ghods: salt – sensitive, Boolani: salt – resistant) on SDS-PAGE electrophoretic pattern of leaf proteins was studied under greenhouse conditions. Generally, in response to salinity treatments, the decrease in protein...

Tiller number is one of the key factors that influences rice plant type and yield components. In this study, an EMS-induced rice tiller suppression mutant ts1 was characterized. Morphological and histological observations revealed that, in the ts1 plants, the tiller buds were abnormally formed and therefore cannot outgrow into tillers. With an F2 population derived from a cross between ts1 and ...

Flooding is a major threat to agricultural production. Most studies have focused on the lower water storage limit in rice fields, whereas few studies have examined the upper water storage limit. This study aimed to explore the effect of waterlogging at the rice tillering stage on rice growth and yield. The early-ripening late japonica variety Yangjing 4227 was selected for this study. The treat...
