“Michael, just remember that when you entered the league, they changed all the rules so you could dominate.  When I entered the league, they changed all the rules to prevent me from dominating!” – Wilt Chamberlain to his verbal combatant Michael Jordan

 

It would have been great to witness this conversation as two all-time greats argue back and forth who was the better player.  As usual, the boisterous Chamberlain was adlibbing a bit when he said, “changed all the rules”, but his overall claim did have a valid point. 

The 1980’s was notorious for referees starting to allow some blatant rule book violations.  How did you like the no-call of the three (or more) step travel, the “count the bucket and one” foul call when the foul was clearly committed before the shot was being attempted, or allowing the super-stars to get away with much more defensive aggressiveness than their counterparts??  Even though the NBA didn’t change the rules per se, the alteration of the game by the referee definitely benefited the more athletic offensive players on the court. 

Shortly after the Bulls championship run in the 1990’s, the NBA liked the trend of smaller players dominating the game.  Therefore, the league officers completely eliminated the illegal defense rules and the defensive hand check rule, as well as implemented the defensive 3-seconds in the lane rule.  This allowed zone defenses, more dribble-drive penetration, and more isolation plays.  Today, most teams are consisted of players that are 6’5” to 6’10”, able to shoot the deep three and athletic enough to prevent a horrific defensive match-up on the crucial screen and switch strategy.  Like it or not, the professional game today is much different than the game played a couple decades ago.

In Wilt’s case, they actually did change the rules to prevent him from dominating the game so easily.  First, the NBA widened the lane from 12 feet to 16 feet.  With the offensive 3-second lane rule already in place, this forced the big men to post-up further from the basket.  Second was a rule change to restrict how the offensive team could inbound the ball from under their basket.  It was common in Wilt’s day for a teammate to throw the ball over the top of the basket on the in-bounds play as an alley-oop.  With Wilt’s height and jumping ability, it was an easy guaranteed two-points.  Third, was changing the free-throw rules.  With Wilt’s consistent inability to make the 15-foot shot, he changed it up by taking a couple step running leap from behind the free-throw line and dunking the ball for a successful point.  These rule changes seem to make obvious sense today, but truthfully, they were implemented because of one man’s dominance.

In the agricultural world as well, the rules are always changing.  We could go through some of the examples, but you know them and have experienced them better than anyone.  It’s hard to say what the rules of the future will entail, but the past trend has been rules modified to make the large farm more difficult to manage.  However, just like Wilt Chamberlain, the dominant players always find a way to be successful! 



Regional Weather

Well, we should start to see some more consistent spring time temperatures; into the 60’s for daytime highs and staying away from those cold nights significantly below freezing.  I think most would agree that it’s time to hit the field as conditions allow for small grains and sugarbeets.  By the time the planters are done with sugarbeets, we should be able to have warm enough conditions for the corn and probably some early soybeans.

The soil temperature chart (oFahrenheit) comes from NDAWN at 8 am Monday, April 26th.  As you can see over last week’s report, soil temperatures are building.  I highlighted in blue any readings below 35F and gave the red highlights to any reading above 41F.  Bottineau clearly remains the coolest spot, while Dickinson, Minot and Williston via for the warmest soils in the state with their very dry conditions out west.



I’ll count on your weather app for the best guidance through the 7-8 day forecast, but looking beyond that, I’ve found this site from National Oceanic Atmospheric Association (NOAA) to be fairly reliable for a general 8-14 day outlook (next week). 

https://www.cpc.ncep.noaa.gov/products/predictions/814day/index.php

For the first full week of May, the forecast for our region looks to have equal chances for both temperatures and precipitation.  This basically means that we have equal chances for either above or below average conditions to develop at this point in time.  Since the forecast does not include a trend to wetter/drier or warmer/cooler, we typically say we should experience normal conditions.  For the first week of May, the normal conditions would most likely entail some precipitation and some cool mornings.

The NOAA organization also provides three month outlooks.  If we would like to get a general forecast for the upcoming harvest season (Aug-Sept-Oct), it can be seen here:

https://www.cpc.ncep.noaa.gov/products/predictions/long_range/seasonal.php?lead=4

This forecast currently predicts above average chances on the temperature potential and below average on the precipitation potential as we move into the later stages of the season for our region.



Soybean Planting

With the trend of shifting soybean planting earlier and earlier to take advantage of extra day length to help drive yield, I’m sure we’ll probably see a few soybeans go into the ground these last few days of April/first few days of May this year.  The biggest risk is frost injury to those soybeans as 32F temps can cause injury to emerged soybean plants, and temps at 28F for four hours or more are typically lethal for emerged beans.  Fortunately, we’ve avoided those late spring frosts for most of the last several years and farms have enjoyed greater success with early planted soybeans.


Today’s seed treatment fungicides are getting more critical, but they have been performing well and are essential for early planting.  For the majority of your soybean acres, I’d probably continue to hold off until we see upper 40sF for soil temperature and a nice forecast in the week following.  Typical soybean planting conditions call for 55F soil temps and a positive continuing warming trend.

For planting soybeans, place seed into consistent soil moisture at 1.5” to 2” deep (about the same or slightly shallower than corn).  If dry soil conditions exist, deeper placement has been successful (2” to 2.5”) to obtain uniform seed to soil moisture contact and more uniform emergence.

USDA Crop Progress Report

The USDA crop reports have been coming out for the past couple weeks, but there has been so little activity, I haven’t bothered to mention them.  Today’s report (Monday, April 26), has the country sitting at 17% planted with only 3% of acres emerged.  If you remove Texas, Tennessee, and North Carolina from those equations where the majority of corn has been planted and emerged, the numbers would be even more quiet.  However, the 5-year average is only 20% of the US corn being planted for this date in late April.  Soybean planting is only 8% complete across the country, but slightly more than the 5-year average of 5%.

Cold Stress in Corn

With some ultra-early corn going in last week, let’s review cold stress symptoms for seedling plants.  Typically, you will find a combination of the below symptoms when conditions are stressful.  In the top photo, we see minimal (sometimes, there will be no) coleoptile growth with primarily radicle growth.  This is usually a symptom of too much soil temperature variability/fluctuation and/or too much cold temperature shock when the corn first was planted.

The bottom photo is abnormal and elongated coleoptile growth.  These symptoms are common with the initial imbibing of water that is very cold.  Also, do you will notice the highly damaged coleoptile tips?  This is evidence of frost damage during emergence.

I’m hopeful that the temperatures will regulate somewhat as we journey into May and the soils will gain enough heat to provide some buffering conditions.  If this should happen, and then we experience a dip in ambient air temperatures, the impact on seedling growth will be diminished.

Why Do Soybeans Yield More With Earlier Plant Dates

Since soybeans are more sensitive to daylight length versus heat units (i.e. corn), we need to think about their yield parameters differently.  With soybeans, early planting is all about driving maximum vegetative growth before the reproductive stages begin.  Early planted soybeans may flower slightly earlier than “normal date” planted soybeans, but it will be a minimal difference of time (a few days). 

Soybeans will continue to add vegetative growth during the flowering and pod development stages, but the more leaf area index (LAI or vegetative foliage) the plant obtains earlier in the season the better yield potential we’ll have.  With more LAI, there will be more resources to produce more energy through photosynthesis, and ultimately support more flower development and increased pod retention.  With more pods being retained, ultimately, we’ll see more seed being produced per plant, and more yield produced per acre.

Random Agricultural Facts – Minichromosomes

Normally, we discuss an aspect of agriculture history in this section, but today we’ll focus a bit on the future. 

As far as Genetically Engineered (GE) crops go, new technology is on the horizon.  Up until now, GE crops have been developed by inserting modified genetic material into native DNA strands within plant chromosomes to obtain the desired genetic expression (i.e. herbicide tolerance to glyphosate).  Many opponents to GE crops do not like the fact that we’re disrupting nature and tainting our food (and/or animal feed) with un-natural genetic material.

Today, we see the added value of stacked GE traits in our crops to stay ahead of and control the ever-evolving pests.  The plant breeders will warn that as we add more and more GE traits to the plant, it becomes more and more difficult to predict the performance of the overall genetic package. 

Looking to the future, how do we overcome the challenges?  Can we engineer an alternative method?  Well, plant scientists have invented minichromosomes to help solve the issue.  Minichromosomes will be a new addition to the plant’s biology and separate from the main chromosomes (however still aid and link with the overall maintenance/function of the plant).  This separation of the mini-chromosomes will allow for cleaner acceptance of the added GE material, but with far less side-affects (i.e. “yield-drag” and agronomic trait weakening).

With minichromosomes, we should greatly minimize the risks since we are not altering the native endogenous chromosomes.  The trick will be in how the native plant accepts the minichromosomes and allows them to perform.  Will it be synergistic or antagonistic?  Or, a little of both within certain aspects of the plant?  The plant breeding and biology faction of agriculture can truly be amazing at times!
