Performance of heat-tolerant lettuce cultivars in Southern New Mexico in 2020—21


Lettuce (Lactuca sativa) is a high-value crop cultivated worldwide. Harvested lettuce acreage in New Mexico, USA, trails the leading lettuce production states (California, Arizona), but growers in New Mexico are interested in expanding their production. For New Mexico farmers to increase lettuce production to reach new markets, information on heat-tolerant cultivar performance is needed.

Researchers from New Mexico State University have published new findings on the performance of heat-tolerant lettuce cultivars in Southern New Mexico. The study, conducted during the 2020-21 growing seasons, highlights the potential of specific lettuce varieties to thrive in high-temperature environments, offering significant benefits to local farmers and the agricultural industry.

The study evaluated six lettuce cultivars under the region’s challenging climatic conditions. Southern New Mexico’s high temperatures and intense sunlight can be detrimental to traditional lettuce varieties, making it crucial to identify cultivars that can withstand heat stress without compromising yield or quality.

To determine which cultivars and types of lettuce are better suited for southern New Mexico, researchers measured the following variables: marketable harvest weight, number of days from transplant to first bolt, and number of days from transplant to 50% bolted.

Temperature is one of the main factors affecting the germination and growth rate of lettuce. Higher temperatures often reduce lettuce yield and cause physiological disorders such as premature bolting, tipburn, and ribbiness (protuberances of the outer ribs that prevent normal head development). One of the main methods of overcoming temperature limitations for lettuce production is cultivar selection. Seed companies have many listed heat-tolerant lettuce cultivars, some of which have been evaluated in different locations and many cultivars have been found to be heat-tolerant in specific locations. Heat tolerance is the capacity of plants to function and remain productive under high-temperature stress.

Bolting, when lettuce transitions from vegetative growth to reproductive growth, is promoted in lettuce when temperatures exceed 86 °F. After bolting occurs, the edible portion of lettuce can no longer be harvested. Early bolting could be related to a high sensitivity to increased temperature and is not a desirable trait for lettuce cultivation in warmer temperatures.

This research trial is the first to identify optimal lettuce cultivars for the southern New Mexico region. The consistently high yield of romaine-type lettuce cultivar Sparx makes it a suitable option for growers in southern New Mexico. ‘Sparx’ was productive into the warmer months of the summer, while ‘Mikola RG10’ (butterhead type) and ‘Muir’ (green leaf type), demonstrated slower bolting in 2021. These cultivar performance results offer an initial starting point for further research into appropriate planting dates for southern New Mexico lettuce growers.

Local children capture dreams with cameras at museum event


Local children at the Albuquerque Museum got cameras to keep and used them to capture their hopes and dreams.

ALBUQUERQUE, N.M. – Local children at the Albuquerque Museum got cameras to keep and used them to capture their hopes and dreams.

Saranam teamed up with Pictures of Hope for the event at the Albuquerque Museum. KOB 4 was there as children shared what they want in life and got a surprise.

“My dream is to be a farmer, go to college, a crazy cat lady, a crazy dog lady,” Janise said.

Linda Solomon said the children focused on goals like college and having a home.

“I don’t think there could be anything more special than having children share their dreams,” Linda Solomon said. “Their dreams are so unselfish, they’re not hoping for iPads or things like that, they’re hoping to go to college, to have a home.”

Janise said dreaming helps children plan for the future.

“You can’t really know what you’re going to do if you don’t have like a dream to do it,” Janise said.

“We surprise them with cameras they get to keep,” Solomon said.

Solomon said parents sometimes learn something new when children describe their goals.

“So often parents say to me, ‘I didn’t know my child was dreaming for this in life, I had no idea,’” Solomon said. “We care about their dreams, we care they can achieve these dreams.”

The children will return to the Albuquerque Museum on May 29 for an exhibition. Their pictures will be printed on greeting cards and proceeds will go back to Saranam.

2026 El Santuario de Chimayó and Tomé Hill pilgrimages


NEW MEXICO (KRQE) – Thousands of people will be making their annual pilgrimage to El Santuario de Chimayo in northern New Mexico and Tomé Hill near Los Lunas Friday morning. The walks are in honor of Good Friday, with many people walking dozens of miles to complete their journey.

Each year many make the trek to the northern New Mexico church or Tomé Hill on Good Friday. Some start their journey in Santa Fe, others walk from as far as Albuquerque. The church in northern New Mexico has been a place of worship since the early 1800’s, bringing thousands from across the state for the chapel, shrine and grounds healing powers. The church is considered to be a sacred site and many believe it holds healing properties. Walkers also take the pilgrimage to Tomé Hill. At the top of the hill are three crosses and a shrine where people pray after making the journey.

Officials remind drivers to expect delays and stay alert on the road.

School Danger Zones: Data reveals alarming number of shootings near New Mexico schools


On average, more than once a week, there is a shooting near a school in New Mexico, and nearly half the time, someone is killed.According to data obtained by the Get the Facts Data Team, there have been 833 shootings adjacent to New Mexico’s schools in the past ten years, resulting in 526 people killed.”When you first told me the numbers, I thought I heard you wrong,” said Darren White, former Bernalillo County sheriff and public safety director. “I was shocked that there are so many shootings close proximity to our schools,” White said that numerous state laws make penalties harsher for crimes occurring near schools, including firearm possession and drug dealing. “We put laws in place years ago because we recognize that schools should be sanctuaries, right?” White said.La Mesa Elementary in Albuquerque’s International District leads the list. In the past ten years, there have been 24 shootings within 500 yards of this school, resulting in 20 deaths. However, this school is not alone in being close to gunfire.A map from the data team shows that statewide, Missouri Avenue and Valley View Elementary Schools in Roswell had 11 and 8 shootings, respectively, while Las Montanas Charter and Lynn Middle Schools in Las Cruces both had 8 and 8 respectively.”If it’s being reported that it’s over 800 in this period of time, how many more are taking place that haven’t been reported that we didn’t know about?” White asked. “And so I would argue, like in many of our crime stats, that number is even higher. And, uh … It’s chilling, it really is.”These shooting have either occurred at or close to the shools.For instance, 16-year-old Andrew Burson was killed right next to the football field at West Mesa High School. Another incident involved a shooting right outside Sandia High School and Christ Lutheran School, which led to both institutions being locked down in the middle of the day.
