One of the most important decisions a farmer will face all year is deciding what variety to plant and in which field to plant it. To ensure that the best possible decision is made next spring, it is important to spend some time looking at yield data. While reviewing data is critical, knowing how to determine whether it is accurate and useful is equally important. Below are some tips for using data to make sound planting decisions next spring.Look for Replicated DataDon’t rely on yield resultsfrom one strip plot on a farm or from a single plot location. Look for data from randomized tests that are repeated multiple times and across multiple locations. Replications in testing increase the reliability of the data and helps to remove variables that can skew results.For strip plot data, was a “tester” used?Strip plots planted on farms can cover large areas of a field. In many fields in the Eastern Corn Belt there are several soil types. If a plot crosses several soil types how can you be sure it is accurate? By planting a “tester” variety at regular intervals within the plot, you can calculate adjusted yields based on the variability of the tester yield across the plot. The use of a tester minimizes the effect soil type variability has on the plot results to ensure more accurate data.Look for consistencyAccording to Bob Nielsen, Purdue Extension Agronomist, “Documented consistency in yield performance is still the key to success in selecting hybrids that will perform well in your farming operation.” When choosing a variety based on plot data, it is important to look for consistent performance—across several plot locations and between multiple years. Choose varieties that consistently performed well in 2014 and 2015, in multiple locations, and different growing conditions.Statistical SignificanceOn published data look for foot notes that indicate the least statistically significant yield difference, or LSD. In many plots, the performance of the top 5 or 10 varieties may not be statistically different. Although there are small differences in yield, statistical analysis of the data indicates that all varieties within the LSD have an equal chance of winning the plot.While plot data can be very useful in making decisions, some plot data is significantly more accurate and reliable. The key to getting the most out of yield data is having the ability to sort through the large amounts of information to identify the data that most accurately and reliably represents varietal performance.

PNP believes drug war ‘still successful’ despite Robredo remark

first_imgPhilippine National Police (PNP) spokesperson Brigadier General Bernard Banac MANILA – The Philippine National Police (PNP) still believes that the government war against drugs is still working despite the remark of Vice President Leni Robredo that the drug menace is still prevalent in the country. PNP spokesman Brigadier General Bernard Banac said in a press conference that the administration’s anti-drug campaign will continue as the public is satisfied with it. Banac cited a Social Weathers Stations survey stating that 82% of adult Filipinos were pleased with the anti-narcotics campaign resulting in an “excellent” net satisfaction rating of +70. “Mananatili po ang ating kampanya dahil ito po ‘yung mandato natin at kailangang gampanan para sa ating mga mamamayan,” he said.center_img Banac added: “Well ang atin pong isinagawang anti-illegal drug campaign ay meron pong 82-percent approval satisfaction from our public so ‘yun po ang magiging batayan namin kaya magpapatuloy ang ating kampanya laban sa illegal na droga,” he added. In an interview with Reuters on Wednesday, Robredo said that Duterte must put an end to the bloody war on drugs as it has been “ineffective” and it was putting a dent on the country’s international image. “We ask ourselves, ‘Why is this still happening?’ The president has already made very serious threats to drug syndicates, to drug lords … and yet it’s still very prevalent, so obviously, it’s not working,” said Robredo./PNlast_img read more
