Ladino Superior in Mid-Summer. 

 Botanical separations of pasture for- 

 age, produced on land seeded to la- 

 dino clover and one of the large 

 grasses, give an indication of the 

 usefulness of ladino clover as a 

 pasture in midsummer. The plots on 

 which the samples were taken were 

 seeded in 1942, 1943, and 1945. The 

 average percentages of grass and la- 

 dino at different dates for all plots 

 harvested were as follows: 



The data indicate that while ladino 

 clover may not amount to more than 

 one-quarter of the total forage in the 

 early part of the season, by July it 

 reaches a total of about one-half of 

 the forage, and drops again during 

 the cooler fall weather to about 40 

 per cent of the total forage produced. 



While the large grasses such as 

 timothy, smooth brome, and orchard 

 grass vary some in their ability to 

 produce forage during the hot sum- 

 mer months, ladino shows up best 

 during July and August, by produc- 

 ing abundant forage then.

Fertilizers on the PIoiv Sole Are 

 Effective. Sweet corn responds as 

 well to fertilizers that are placed on 

 the plow sole as to those that are 

 applied with the planter. A more 

 efficient method, however, is to di- 

 vide the application and place half 

 the fertilizer on the plow sole then 

 band the other half with the corn 

 planter or band half the fertilizer 

 and apply the remainder as a side- 

 dressing at the second cultivation. 



These findings represent the re- 

 sults of four years' work in placing 

 the fertilizers for sweet corn bv 

 different methods as outlined. The 

 yields of sweet corn, when fertilized 



by the four methods, fall into two 

 groups. The higher yields come 

 from the methods where the fer- 

 tilizer is applied and is placed in a 

 divided application; the lower yields 

 come from the treatments in which 

 the fertilizer is all placed in one ap- 

 plication, either on the plow sole or 

 being all applied in bands with the 

 fertilizer attachment on the corn 

 planter. Plow sole application of 

 fertilizer is a relatively new idea and 

 appears to work especially well with 

 corn which has a very strong feed- 

 ing root system. In view of the 

 newer methods of weed control with 

 2, 4-D, and other herbicides, there 

 is a distinct possibility of farmers 

 cultivating their own corn fewer 

 times than has formerly been the 

 custom. Because it has been com- 

 mon practice, in sweet corn growing 

 areas, to apply approximately half 

 of the fertilizer at the second or 

 third cultivation it is felt that this 

 project is particularly timely. When 

 it is followed, farmers need not de- 

 pend upon side-dressing if they wish 

 to omit certain cultivations but can, 

 if they wish, plow half their fertilizer 

 prior to planting with equally good 

 results.

Magnesium in Potato Fertilizers 

 Pays Dividends. Three years' re- 

 sults at Colebrook indicate an aver- 

 age dividend of 75 bushels of pota- 

 toes per acre each year when mag- 

 nesium is added to the fertilizer. 

 The quantity of magnesium was rel- 

 atively small, being equivalent to 40 

 lbs. of magnesium oxide per acre. 

 Chemical analyses of soil samples 

 from potato fields in the principal 

 potato-producing areas in the state 

 indicate that similar dividends might 

 be expected in many cases. It is 

 interesting to note that of the first

 qualified in the New Hampshire 300
