...n order to determine the phenology of the predator Coccinella septempunctata Linnaeus (Coleoptera: Coccinellidae) and to evaluate its efficacy on Macrosiphum rosae (Linnaeus) (Hemiptera: Aphididae) in Kastamonu, Turkey. Rearing of C. septempunctata was carried out at 21.3±4.00ºC and 78.8±9.44% relative humidity. The first, second, third and fourth larval instars of C. septempunctata consumed 20.3, 54.3, 108.2, and 232.7 M. rosea, respectivel...

Yield and quality of cotton were significantly higher when crop was grown from seeds stored in polythene bag as compared to cloth bag. Interaction of genotypes and seed sources indicated that highest sympodial branches plant-1 (19.11), days to 50% flowering and boll splitting (72.00 and 156.33, respectively), number of bolls plant-1 (20.33), boll weight (4.60 g)...

...nt on maize (Zea mays L) phenology and crop stand in 2013 and 2014. Treatments included mulching techniques (i.e. no-mulch, residue, transparent and blue colour plastic) and 250 kg N ha-1 sources (control, 100, 70, 50, 0% from FYM with the remaining from urea). Phenological stages (tasseling, silking, and physiological maturity) occurred earlier in no-mulch practice, but emergence in plastic mulching. Plants took less days to emergence (6 days) in 70% FYM, how...

...arieties only. Both crop phenology (i.e. days to tasseling, silking & maturity) as well as morphology (i.e. plant height, ear height, including ear length) was affected (p<0.05)by sowing dates. Likewise, yield traits (i.e. rows per ear, grains per ear, thousand grain weight) were also adversely affected by sowing dates, which decreases both biomass and grain yield. Varieties did differ in phenology (i.e. emergence, si...

...ause for a shift in crop phenology as well as failure of crop calendar. Yellow stem borer (YSB) is an insect pest of rice crop that may reduce rice yield about 20% due to the use of insecticide at inappropriate times and unsuitable locations following the crop calendar. The purpose of this research was to delineate the vulnerable zones for YSB attacks on rice crop using satellite thermal datasets. The area under investigation was 13700 km2 area out of which 86...

...he data showed that crop phenology, growth, and yield of maize were significantly affected by both hybrids and potassium ratios. Maize hybrids and potassium ratios did differ in crop phenology (days to emergence, tasseling, silking, and maturity) and crop growth (single leaf area, leaf area index, and plant height) which resulted in different grain yield. Among hybrids DK-Garanon gave highest value for all the studied parame...

The experiment comprised of four moisture levels (optimum water, 10%, 20% and 30% reduced irrigation water), three chemicals (salicylic acid 0.5mM, potassium nitrate KNO3 1% and methanol 20% v/v basis) applied at three different stages (bud formation, 20% flowering and 20% pod formation). The experiment was laid out in RCB design with split plot arrangement having three replications. Moisture level...

Safflower treated with salicylic acid could adapt to wide range even though in the extreme weather and drought conditions in rainfed agriculture. Spineless safflower cultivars could be a future way forward as a potential parallel crop to ensure a sustainable source of production in rainfed regions worldwide.

In current examination, a field test was directed to evaluate the phenology, relative development, ideal sowing time, comparative growth just as yield execution of three cultivars of Bacillus thuringiensis Cotton (Bt. Cotton) at different sowing sy...
