The effects of preceding crops and fertilizers on the stability of spring wheat yields on chernozems of Altai Priob'e

, : The effects of preceding crops and fertilizers on the stability of spring wheat yields on chernozems of Altai Priob'e. Sibirskii Vestnik Sel' skokhozyaistvennoi Nauki ( 4): 22-25, 132

The results of a 12-year rotation and fertilizer trial and regional agrochemical reports for 1976-84 were used to calculate the stability of spring wheat yields. Yields were least variable in the E. part of the region (Altai foothills) with 500 mm annual precipitation and were most unstable in the Kulunde steppe region (250 mm precipitation), where the coefficient of variation was 35%.

In laboratory studies, ten commercial formulations of 2, 4-D were found to contain 2, 4-dichlorophenol as an impurity. Liquid formulations contained more of the phenol per unit weight than did the granular forms. The 2, 4-dichlorophenol released f...

A total of 8 fennel cultivars were compared in 2 biennial trials at Villalba in 1989-93. Seed yields were very low (69.7 kg/ha) in 1989/90 but increased to 538.7-670.3 kg/ha in 1990-93. In the first year of each biennial trial there were no signif...

Gene promoter systems that drive high-level, long-term, and cell-specific transgene expression are of great interest because of their potential utility for gene therapy. To generate an efficient promoter system specific for noradrenergic (NA) neur...
