Abstracts |
Experiments were conducted during 1999-2000 in Solan, Himachal Pradesh, India, to study the effect of biofertilizers on the growth, productivity and nutrient content of olive cv. Frontoio. The treatments comprised: 750:500:500 g NPK/tree (T1); three-fourth dose N + full-dose P + 20 g Azotobacter/tree (T2); two-third dose N + full-dose P + Azotobacter (T3); one-half dose N + full-dose P + Azotobacter (T4); three-fourth dose N + full-dose P + 20 g Azospirillum/tree (T5); two-third dose N + full-dose P + Azospirillum (T6); one-half dose N + full-dose P + Azospirillum (T7); three-fourth dose P + full-dose N + 200 g vesicular arbuscular mycorrhiza (VAM)/tree (T8); two-third dose P + full-dose N + VAM (T9); and one-half dose P + full-dose N + VAM (T10). T1 gave the highest increase in tree canopy volume, fruit set percentage, and P content. T2 gave the highest increase in trunk cross-sectional area, shoot growth, relative growth rate, leaf area, yield, oil content, N content, and Azotobacter population in the soil. The highest S content and Azospirillum population in the soil was obtained with T3 and T5. T7 gave the highest fruit drop percentage and contents of K, Ca and Mg. T8 gave the highest VAM soil population and root colonization.. |
