NINETEENTH ANNUAL YEAR BOOK— PART X 581 



Harvest is finished in the south except some late fields, and threshing is in 

 full progress. Yields are generally good and quality excellent. In Scott county one 

 field of wheat yielded 55 bushels per acre. While oats yields are good, no phenome- 

 nally heavy yields like last year have been reported. Scab has seriously affected 

 Fpring: wheat in many sections and "barley stripe" is common. Very little 

 black stem rust is reported. 



The hot weather at intervals through the season has reduced the early potato 

 crop to considerably below normal; blight is prevalent. Gardens are needing rain. 

 Homegrrown tomatoes are on the market in the central portion of the state. 



Bulletin IVo. 17, Joly 30, 1918 — 



Hot weather prevailed with maximum temperatures above 90 degrees nearly 

 every day. The 'highest reported was 105 dgrees at Clarinda on the 28th Temper- 

 atures averaged about 5 degrees above normal. Rainfall was heavy to excessive 

 in the northern districts and very deficient in the central, south central and south- 

 west districts. High winds and hall occurred In some northern counties 



The rains delayed harvesting In the north and together with the high wind 

 caused oats to lodge so that many fields can be cut only one way. Considerable 

 of the late oats and spring wheat remains to be cut In the northeastern district 

 where In places the fields are too wet for the binders. The yield of spring wheat in 

 Blackhawk county has been reduced 50 per cent by rust. Threshing Is progressing 

 in all but the northeast district. Yields are generally good. 



Corn has made good progress except In the southwest one-fourth of the state 

 where extreme heat and serious drouth have caused It to fire on thin uplands In 

 other sections corn Is earing well and promises an unusually large crop Strong 

 winds blew the corn down badly in the northern districts, but it is generally straight- 

 ening up. In general the crop is two or three weeks ahead of last year Earlv 

 sweet corn Is being used In the north. 



Pastures have failed In the southwest and live stock has been put on winter 

 feed. Potatoes and garden truck In this section have been damaged by drouth 

 Home grown tomatoes are on the market in nearly all sections. 



Bnlletin No. 18, August 6, 1918 — 



Abnormally cool weather weather with a minimum temperature of 46 in Dela- 

 ware county on July 31st was followed by Intense heat in the south half of the 

 state. At Pella the temperature range was 65 degrees, from 47 on July 31st to 112 

 on August 4 th. The highest temperature was reported as 113 at Clarinda on the 

 4th, equaling: the highest ever recorded in the state. In the southwest one- 

 fourth of the state, high temperature records of 40 to 46 years were broken 

 Ramfall of agricultural importance was confined to about 15 counties in the 

 northeastern part of the state. The southwest part, which has been deficient 

 in rainfall for several weeks, suffered seriously from three days of intense 

 heat and the strong southerly winds of Mo.nday, August 5th. Corn has been 

 injured 50 per cent or more in many southwest counties, and, unless rain 

 comes soon, it will be nearly a total loss. In the northern and eastern por- 

 tions, prospects for corn were never better. The crop has advanced rapidly, 

 roasting ears are reported in all sections and the earliest has begun to dent. 

 Threshing Is 50 to 75 per cent completed in the southern half of the state and 

 In full progress in the north. Yields are generally good to excellent and quality 

 good. Wheat is being hauled to market direct from the machines. Blight and 

 aphis are seriously affecting late potatoes which will not yield as well as has 

 been indicated. Garden truck is sulTerlng for rain except in the northeast dis- 

 trict and is practically a failure in the southwest. 



Pasture and new seedings of clover and other grasses have failed gen- 

 erally in the south and west. Plowing, in preparation for a large acreage o* 

 winter wheat, has begun in many sections. 



Bulletin No. 19, August 13, 1918 — 



Hot weather continued In nearly all parts of the state except on the 8th and 

 9th when cooler weather prevailed. The mean temperature averaged about 8 degrees 

 above normal. Most stations had temperatures of 100 or higher on one or more
