application resulted in calcium accu- 

 mulation by vegetative tissues but that 

 vv^hen used consecutively for 5-6 years 

 the foliar concentration of some ele- 

 ments increased while that of others 

 decreased, indicating a need for fur- 

 ther research. 



Recognizing that the growing of 

 small fruits in New Hampshire offered 

 an attractive opportunity for orchard- 

 ists and part-time farmers, Pollard 

 evaluated management systems with 

 the objective of increasing fruit yield 

 and quality yet decreasing the require- 

 ment for hand labor. 



The planting of semi-dwarf apple 

 trees has been strongly urged by W. 

 Lord, Cooperative Extension fruit spe- 

 cialist — they can be more densely 



planted, mature earlier, are easier to 

 prune, spray and pick, and have fruit 

 quality equal to that of full-sized trees. 

 His research has shown that, although 

 late summer pruning of semi-dwarfs 

 has a few disadvantages, it keeps tree 

 size small, improves fruit color and 

 quality and may increase winter har- 

 diness. 



Some scientists in Plant Science 

 have found that providing an answer 

 to a perplexing question is often as 

 difficult as developing a new plant 

 variety, equally challenging, and 

 sometimes just as rewarding.
