Nutritional quality of different potassium efficiency types of vegetable soybean as affected by potassium nutrition

Reproduction in the guinea pig as affected by chronic administration of potassium nitrate and potassium nitrite.

Toxicosis produced by nitrates and related compounds is a problem in man and in domestic animals. The most prominent effect of nitrate and nitrite is the conversion of hemoglobin to methemoglobin. Nitrate must be reduced to nitrite before excessive -methemoglobinemia occurs. Nitrites are therefore several times more toxic than nitrates. -· Pharmacologically, KN03 had been used as a diuretic, an...

Yield and fiber quality of Upland cotton as influenced by nitrogen and potassium nutrition

Nutrient stress in Upland cotton (Gossypium hirsutum L.) depresses lint yield, particularly of late-season fruit (bolls), and may disrupt fiber development. A 2-year (1999 and 2000) study was conducted outdoors in large pots to determine individual effects of nitrogen (N) and potassium (K) stress at flowering stage on lint yield and fiber quality. Treatments were half-strength nutrient solution...

Factors Affecting Potassium Nutrition

FIGURE 1 Potassium response curves for plant and ratoon cane crops. Recent trials Since the exploratory and RFT series of trials more than 70 trials have been conducted. Many of these trials are still in progress but the results so far may be summarised as follows: The combined average responseto the 93 kgK haI treatment was 5,5 tc ha" while a further 93 kg Khat gave little additional response

Vegetative growth and chemical composition of tomato plants as affected by different types of salt stress and zinc fertilization

Effect of Absorbent Granules Coated by Potassium Permanganate on Postharvest Quality of Rose (Rosa hybrida) Cultivars

Enrichment of zeolite and sponge as ethylene absorbent with potassium permanganate was theidea of this study to provide an efficient way to scavenge ethylene during storage period ofthree Rosa hybrida cv. ‘Shiraz’, ‘Avalanche’, and ‘After-party’ cut flowers. A preliminaryexperiment revealed that two mL of potassium permanganate solution (1 mM) was enough toenrich two gra...
