ABSTRACT The use of organic fertilizers can improve the chemical, physical, and biological properties soil, with their implying low environmental impact. This study aimed to evaluate yield quality yellow passion fruit grown in an system associated irrigation input levels. A randomized complete block design a 3x2 factorial arrangement four replications was adopted. factors evaluated were: three ...
Inappropriate organic fertilizer application may cause serious environmental risks, especially nitrogen (N) and phosphorus (P) losses. To achieve a win–win for high yield protection in agriculture, it was essential to demonstrate the relationship between input, rice yields, risks of N P Based on green manure cropping rotation field experiment Yangtze River Delta China, effects fertilization rat...
Recently, application of biofertilizers has been introduced as a new strategy in crop nutrition. In order to investigate the effect of application methods of biofertilizer in combination with nitrogen levels on yield and yield components of weed-infested triticale a field experiment was conducted at College of Agriculture and Natural Resources of Darab, Shiraz University in 2013-14 growing seas...
THE KEY to improving the native tussock grasslands of the South Island is to obtain good legume growth. In these areas, the main nutrient deficiencies which limit the growth of legumes are sulphur, phosphorus and molybdenum. Sulphur deficiencies are very widespread (Walker et al., 195.5; Lobb and Bennetts, 1958; McLeod, 1961). The manner in which a rational fertilizer programme was formulated f...
