This study was to determine whether Arthrobotrys flagrans, A. oligospora, and Meria coniospora would control the root-knot nematode Meloidogyne hapla on alfalfa and tomato. Alfalfa seeds were coated with a fungus-rye powder in 2% cellulose and were planted in infested soil. Three-week-old seedlings from seed treated with M. coniospora had 60% and 58% fewer galls in two experiments than did seed...

A large percentage of Bollgard cotton is treated for bollworms [Helicoverpa zea (Boddie)] with little information about economic losses from these infestations. The impact of bollworm infestations on maturity and yield of Bollgard cotton was determined. Infestations of 1-d-old bollworm larvae were established on non-Bollgard and Bollgard cottons in large field cages. Treatments included three a...

The present study employed white (W), blue (B: 468 nm), red (R: 629 nm) and green (G: 524 monochromatic LED lights for 26 days, from 11:00 to 18:00 (7 h per day), with a average of photosynthetic photon flux density (PPFD) 26.00 m-2 s-1 on two baby leaves spinach (Spinacia oleracea L.) cultivars (Falcon F1 Viroflay) grown in hydroponic system. Regardless the cultivar, fresh dry weights were pos...

Aquaponics is a promising cultivation technique for combined production of crops and fish, on the condition tackling certain nutrients deficiencies. The aim present study was to examine limitations imposed by system spinach (Spinacia oleracea) growth functional performance identify minimum nutrient supplementation their optimization.

The d-glyceraldehyde 3-P dehydrogenases of spinach leaf, pea seed, and pea shoot were purified. The NADP and NAD-linked enzymes of either spinach leaves and pea shoots could not be separated. Changes in the ratio of NADP- to NAD-linked activity of the spinach leaf and pea shoot enzymes were observed during both purification and storage of crude extracts. The spinach leaf, pea shoot, and pea see...
