However, the past two years were bleak for the agriculture sector following the government\u2019s&nbsp;<a href=\"https:\/\/time.com\/6196570\/sri-lanka-crisis-organic-farming\/\" target=\"_blank\" rel=\"noreferrer noopener\">agrochemical importation ban<\/a>&nbsp;in April 2021, triggering a severe economic and food crisis. Although the financial nosedive also impacted scientific research and development, Sri Lankan agronomists have been working to improve the situation and restore agriculture.<\/p>\n\n\n\n<p>Bringing such efforts to fruition, agronomists at the Sri Lanka\u00a0<a rel=\"noreferrer noopener\" href=\"https:\/\/sugarres.lk\/\" target=\"_blank\">Sugarcane Research Institute<\/a>\u00a0(SRI) presented a sweet treat to the nation in July 2023. They introduced four new improved cultivars of sugar cane (<em>Saccharum officinarum<\/em>) along with some technological and policy innovations linking researchers, farmers, and industry. Working in a highly challenging environment, researchers at SRI developed these new sugar cane varieties that promise increased productivity, offering some hope. The new varieties were created through crossbreeding in field experiments.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.lankaweb.com\/news\/items\/wp-content\/uploads\/2023\/10\/image.png\" alt=\"\" class=\"wp-image-137888\"\/><\/figure>\n\n\n\n<p>Sweetening the pot for farmers, they also developed an app called&nbsp;<em>Uksaviya<\/em>&nbsp;(translating to strength of sugar cane\u201d). The first of its kind to be introduced by an agricultural research institute in Sri Lanka, the app can help farmers identify diseases and apply effective cultivation methods and find relevant current study results. The institute has been catering to technological and technical requirements of the industry since 1981.<\/p>\n\n\n\n<p>Established as a commercial cultivation in the late 1950s, sugar cane is a multipurpose crop, mainly used for sugar, ethanol, and biofuel production in Sri Lanka. However, only 15% of the national sugar requirement is fulfilled by&nbsp;<a href=\"https:\/\/sugarres.lk\/cost-of-sugar-production\/\" target=\"_blank\" rel=\"noreferrer noopener\">local<\/a>&nbsp;production, compelling the country to import sugar at a high&nbsp;<a href=\"https:\/\/sugarres.lk\/sugar-import-data-per-capita\/\" target=\"_blank\" rel=\"noreferrer noopener\">cost<\/a>. SRI\u2019s crop physiology experts and sugar manufacturers say that a major hurdle is the sugar recovery percentage of the sugar cane variety routinely grown in Sri Lanka being as&nbsp;<a href=\"https:\/\/sugarres.lk\/statistics-of-the-sugar-sector\/\" target=\"_blank\" rel=\"noreferrer noopener\">low<\/a>&nbsp;as 6-8%, according to SRI data. Comparatively, varieties grown in top sugar cane-growing countries have a sugar recovery percentage as high as&nbsp;<a href=\"https:\/\/doi.org\/10.1007\/s12355-021-00951-1\" target=\"_blank\" rel=\"noreferrer noopener\">15%<\/a>.<\/p>\n\n\n\n<figure class=\"wp-block-image\" id=\"attachment_274624\"><img decoding=\"async\" src=\"https:\/\/imgs.mongabay.com\/wp-content\/uploads\/sites\/20\/2023\/10\/25073050\/Preparing-female-plants-for-breeding.jpg\" alt=\"\" class=\"wp-image-274624\"\/><figcaption class=\"wp-element-caption\"><em>Farmers prepare sugarcane plants for breeding.

As farmers get paid for the weight of cane harvested, they mostly prefer varieties that give a higher cane yield.<\/p>\n\n\n\n<p>However, the low sugar recovery percentage of currently grown varieties makes it less profitable for the factories. Ratnayake says the new varieties having improved sugar recovery with high cane yield is a step toward a win-win for both sugar cane growers and sugar manufacturers.<\/p>\n\n\n\n<figure class=\"wp-block-image\" id=\"attachment_274625\"><img decoding=\"async\" src=\"https:\/\/imgs.mongabay.com\/wp-content\/uploads\/sites\/20\/2023\/10\/25073255\/Aerial-image-of-a-Sri-Lankan-sugarcane-field-768x512.jpg\" alt=\"\" class=\"wp-image-274625\"\/><figcaption class=\"wp-element-caption\"><em>An aerial view of a sugarcane field in Sri Lanka.

The new varieties have better ratoonability, the agricultural practice of having two harvests during one cropping season, allowing farmers to re-grow crops from the stubble remaining after harvesting the first.<\/p>\n\n\n\n<p>Three out of the four varieties have high productivity under rainfed conditions, suggesting their improved drought tolerance. These are features that would improve cost efficiency for farmers in terms of replanting and irrigation, Costa told Mongabay.<\/p>\n\n\n\n<figure class=\"wp-block-image\" id=\"attachment_274626\"><img decoding=\"async\" src=\"https:\/\/imgs.mongabay.com\/wp-content\/uploads\/sites\/20\/2023\/10\/25073515\/Farming-association-leaders-keeping-records-on-crop-to-assist-the-SRI-in-collecting-data-for-improvement-of-the-cultivation-768x512.jpg\" alt=\"\" class=\"wp-image-274626\"\/><figcaption class=\"wp-element-caption\"><em>A sugarcane farmer keeping records.

The four new varieties are the result of experiments since 2003.<\/p>\n\n\n\n<p>Perera, a senior scientist in Udawalawa, in Sri Lanka\u2019s deep south, told Mongabay: The onset of&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/COVID-19\" target=\"_blank\" rel=\"noreferrer noopener\">COVID-19<\/a>&nbsp;and the economic crisis that followed presented challenges with industry testing, travel restrictions and manpower shortages. Nevertheless, with the resources and expertise available to us, we are continuing our research on testing new cultivars, with more varieties lined up to be introduced soon, which we hope to recommend to other sugar cane-growing countries in the region as well.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image\" id=\"attachment_274627\"><img decoding=\"async\" src=\"https:\/\/imgs.mongabay.com\/wp-content\/uploads\/sites\/20\/2023\/10\/25073713\/Jaggery-one-of-the-main-products-made-with-extracted-sugar-768x512.jpg\" alt=\"\" class=\"wp-image-274627\"\/><figcaption class=\"wp-element-caption\"><em>A key product made from sugarcane is jaggery, locally known as hakuru\u201d.

That expert system is integrated into a software, which can reason and diagnose diseases and nutrient deficiencies. This way, the knowledge and reasoning ability limited to only a few becomes available to a wider audience at their fingertips,\u201d he said.<\/p>\n\n\n\n<p>Uksaviya also includes advice on land preparation, cultivation methods, fertilization, and sugar cane-based products, as well as the latest research findings. Lahiru said Uksaviya mainly targets the young generation of farmers. He said he believes that at a time when most young farmers are abandoning sugar cane cultivation and seeking other professions, integrating these kinds of modern technologies into their farming culture would encourage them to remain in the industry and reap the benefits of the latest findings through efficient knowledge exchange.<\/p>\n\n\n\n<figure class=\"wp-block-image\" id=\"attachment_274628\"><img decoding=\"async\" src=\"https:\/\/imgs.mongabay.com\/wp-content\/uploads\/sites\/20\/2023\/10\/25073836\/SRI-officers-working-with-farmers-in-the-sugarcane-fields-offering-advice-and-guidance-2-768x512.jpg\" alt=\"\" class=\"wp-image-274628\"\/><figcaption class=\"wp-element-caption\"><em>It\u2019s combined work when SRI officers work closely with farmers.

Having recently completed his Ph.D. at the University of Tsukuba, Japan, Ariyawansha was inspired to adapt the research policies he absorbed while in Japan.<\/p>\n\n\n\n<p>He got an ideal opportunity to execute that vision when the&nbsp;<a href=\"https:\/\/nia.gov.lk\/\" target=\"_blank\" rel=\"noreferrer noopener\">National Innovation Agency<\/a>&nbsp;(NIA) collaborated with SRI to restructure its research policy.<\/p>\n\n\n\n<p>Ariyawansha told Mongabay: We created a business link with a framework where the sugar cane industry can request research that they find necessary. Institutional researchers can combine their ideas and expertise with those requests and carry out precise research that solves existing problems.\u201d<\/p>\n\n\n\n<p>Ariyawansha said this facilitates institutional researchers to propose their research ideas to the industry and assess its commercial relevance. This improves precision of research while ensuring the proper distribution of benefits among all parties involved in the research and the protection of intellectual property rights. Further, resources could be allocated for research with pressing industrial needs while researchers also get commercial benefits for their work.<\/p>\n\n\n\n<figure class=\"wp-block-image\" id=\"attachment_274629\"><img decoding=\"async\" src=\"https:\/\/imgs.mongabay.com\/wp-content\/uploads\/sites\/20\/2023\/10\/25074135\/A-farmer-bringing-in-the-harvested-sugarcanes-e1698219728475.jpg\" alt=\"\" class=\"wp-image-274629\"\/><figcaption class=\"wp-element-caption\">A farmer brings his harvest home.
