How reliable will this year’s test plot data be?

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Ohio’s corn and soybean crops experienced exceptional growing conditions in 2015, including record rainfall in June and July followed by a drier than normal August conditions in many areas. The persistent rains saturated soils and caused localized ponding and flooding. These conditions resulted in root damage and N loss that led to uneven crop growth and development between and within fields. Agronomists often question the value of test plot data when adverse growing conditions severely limit yield potential.The validity of test plot results depends primarily on whether effects of the varied stress conditions are uniform across test plots. If not, test plot data may be questionable. To be certain that effects of stress were fairly uniform, it would be necessary to monitor test plots on a regular basis to determine crop response to the various stresses as they occurred; however, such monitoring was probably unlikely in many test plot fields.Another problem with test plot results is that the various yield limiting factors may accentuate the natural “variability” already existing in the field, and may thereby further “mask” the true treatment effects that are being compared. Stress conditions like the ponding and saturated soils this year coupled with slight differences in soil organic matter, drainage, weed control, etc. across a field may magnify differences in crop performance.If one assumes that the varied stress conditions affected test plots uniformly within a field, then interpretation of test plot data becomes an issue. This issue can be especially relevant when evaluating results of hybrid and cultivar performance trials affected by excessive soil moisture. Did a hybrid or cultivar yield well under saturated soils because it genuinely possessed some flooding tolerance or because it was planted in better drained areas of the field? This year we have more than a 100 bushels per acre difference in plot yield between hybrid entries planted at different locations within a field that are related to soil drainage and N loss. Usually there are striking visual differences between such plots associated with plant height and overall plant health but differences are not always pronounced.Test plot information this year can still be very useful but take precautions. Results from single on-farm strip tests should not be used to make a decision on adoption of a treatment or variety. Even replicated data from a single test site should be avoided, especially if the site was characterized by abnormal growing conditions. Use test plot data from multiple sites (and preferably from at least two years of testing) and inquire about the weather patterns and conditions associated with the results. Look for consistency in a product or cultivar’s performance across a range of environmental conditions.last_img read more

WB Governor sends report to Centre

first_imgWest Bengal Governor Keshari Nath Tripathi has sent a report to the Centre on Friday on the ongoing violence in Darjeeling over the demand for a separate Gorkhaland State. “In the report, the Governor said all the stakeholders involved in the Gorkhaland issue should try to resolve the matter through discussion and restore peace in the Darjeeling hills,” sources in the Raj Bhavan told The Hindu.Earlier on Friday, a delegation of three Gorkha Janmukti Morcha (GJM) MLAs — Amar Singh Rai, Rohit Sharma and Sarita Rai — met the Governor and apprised him of the situation in Darjeeling. “The GJM delegation also stated that the State government is yet to issue any formal order stating that Bengali will not be made compulsory in the schools in the hills,” sources in the Raj Bhavan said. ‘Outsiders’ work’Addressing the media after the meeting, Mr. Sharma claimed that “those who are indulging in arson in Darjeeling are not GJM members but outsiders.” He also said the delegation had urged the Governor to “inform the Centre about the situation in Darjeeling and the suffering of the locals due to the State government’s stand over the Gorkhaland issue.”The GJM delegation also accused the State Government of “using force to disrupt the peaceful movement for the separate State.” (With PTI inputs)last_img read more

IPL 2011: Chennai Super Kings vs Deccan Chargers- CSK win by 19 runs

first_imgChennai batsman Suresh Raina scored a fine 59 and Albie Morkel scalped three as their team beat Hyderabad by 19 runs during their IPL match at the MA Chidambaram Stadium in Chepauk on Sunday. Score | PhotosHyderabad players were aware that a target of 166 would prove to be a tough one to reach so their openers Sunny Sohal and Shikhar Dhawan started off on a high note scoring close to 12 runs an over. But it was Sohal, who was doing the bulk of scoring and Dhawan providing him with the much-needed support.Sunny Sohal raced to his half-century in no time. But in the 7th over of the innings he was forced to take a walk after putting a 30-ball 56. The reason Shadab Jakati’s ball crashed into his stumps when the score was 71.Jakati struck again on the last ball of the 11th over scalping the other opener Dhawan on 19. Jakati kept the ball low and an inside edge of Dhawan’s bat crashed into his stumps and Hyderabad were 90/2.Bharat Chipli fell in the 14th over off Albie Morkel and Chennai were down to 110/3.  Then Doug Bollinger clean bowled Hyderabad captain Kumar Sangakkara in the 16th over to reduce the visitors to 121/4.Cameron White ended up getting caught by substitute Faf du Plessis off Morkel on the first ball of the 18th over when the score was 137. The last ball of the same over saw JP Duminy walk back on 17 and Hyderabad were down to 143/6.More wickets fell in the last over as Daniel Christian ended up getting run out in Doug Bollinger’s over.advertisementFinally Hyderabad could only manage to score 146/8.Chennai inningsEarlier, Suresh Raina scored a fine 59 as Chennai posted an impressive 165/5 against Hyderabad in the 39th IPL match of IPL-4.Chennai suffered early setback in the fourth over when left-arm spinner Pragyan Ohja scalped opener Murali Vijay with a ball that kept low and skid on to crash against his stumps when the team total was 18. This was after Chennai captain MS Dhoni won the toss and elected to bat.Post that wicket Suresh Raina and opener Michael Hussey got on with a partnership. And by the 10th over the Chennai score was 58/1.Finally in the 13th over Hussey walked back after posting a good 46 runs on board and putting 60 runs for the second wicket with Suresh Raina. Hussey went for a pull off Harmeet Singh but failed to cross the boundary and ended up getting caught by Ishant Sharma when the team total was 78.But Suresh Raina was still at the crease and he went on to score a fine 59 off just 35 balls decorating his innings with six fours and two sixes. Finally, Ojha got the better of him in the 18th over. Raina played took the aerial route but his shot was cut short by Shikhar Dhawan at deep mid-wicket. Chennai were 136/3 post his wicket.Next man Albie Morkel charged away at the opposition bowlers and he picked Ishant Sharma for his batting blitz. He hit a massive six off him in the 19th over and then followed it with another big one measuring 109m and then upped the scale to 114m with the next aerial shot – recording the longest six of the IPL-4 so far.But, Morkel ended up getting run out on the first ball of the 20th over.Captain MS Dhoni, who scored 21, was the last wicket to fall from the Chennai camp. Chennai completed their innings on 165/5 with Subramaniam Badrinath and Srikkanth Anirudha at the crease.last_img read more
