Seasonal conditions during crop growthThe groundnut crop produces optimum yield in the regions receiving rainfall between 200 to 1000 mm8. The total rainfall during groundnut growing season was 257.10 mm and 403.10 mm at Baljigapade in 2018 and 2019, respectively, wherein Pavagada (2018) total rainfall was 53.90 mm (Fig. 1). In 2018, both Pavagada and Baljigapade received very low and negligible rainfall during the reproduction and harvest stage of groundnut. Optimum temperature for groundnut production ranges between 20 to 30 °C and growth and pod formation limited below 16 °C and above 32 °C9. The monthly mean atmospheric temperature was ranged from 23 to 27 °C and 21 to 26 °C at Baljigapade in 2018 and 2019, respectively, wherein Pavagada ranged from 25 to 28 °C. At all three locations, the monthly mean atmospheric temperature was slightly high during the early vegetative growth of groundnut and it was progressively decreased as the crop reaches its maturity stage (Fig. 1). All three locations recorded higher and lower mean monthly sunshine hours (hours day−1) during peg initiation to pod filling stage (September and October) and early vegetative growth of groundnut (July and August), respectively.Growth parameters of groundnutAnalysis of variance revealed that treatment, location, and their interaction had a significant effect on plant height and number of branches at harvest (P  More

I’m from a fishing family. My grandfather was a fisherman when he was a young man, working out of Fano, the Italian town where I grew up and still live. I’m used to the smell of fish.I’m pictured during an overnight shift on the fishing boat RIMAS. I work from 5 p.m. until 9 a.m. with fishermen from nearby Cesenatico on the north Adriatic Sea. It’s a small boat: there’s only six or so of us on board. At night, the fish are most active and we can avoid other vessels.The nets scrape the sea bed for the catch but sometimes they also catch turtles who often die in the nets or on board. That’s where I come in. The net I’m holding is designed to allow turtles to escape: it has a hole at the top they can swim out of. We call it TED — short for ‘turtle excluder device’. The TED is made from a high-strength plastic, and is based on decades of work and research aimed at reducing the bycatch of turtles from trawling. Turtles and some larger fish can leave through the escape hatch, but the current holds most of the catch in the net.I ensure that the net is working, and that the fishermen we’re collaborating with can still catch enough for their livelihoods while protecting turtles. The work is part of research by the Cetacea Foundation, based in Riccione, Italy, in collaboration with the University of Pisa, where I’m a field researcher. It is financed by the LIFE programme, the European Union’s funding instrument for the environment and climate action.I love this work. It means I’m not stuck in an office all day and instead can enjoy the ocean and work closely with people who live by the sea. I get to be a researcher who works outside, rather than being hunched over a microscope.When my grandfather was fishing in the 1970s, there were more fish and more turtles around. At the foundation, we save 50–60 turtles a year, most of them harmed because of fishing. If we can protect turtles by rolling out this device to fishermen all across the Adriatic, I’d see this work as a success.
