Abstract

The study was conducted at the Navsari Agricultural University’smain rice research center in Gujarat, India, during the kharif season (July–November 2023) to assess the resistance of rice genotypes to bacterial blight using an artificial inoculation method. Thirty rice genotypes were evaluated along with two known susceptible varieties viz., GR-11 and TN-1, using the clip inoculation technique under field conditions. Among them, four genotypes viz., NVSR-996, NVSR-1065, NVSR-1127 and ISM showed moderate resistance. Fifteen genotypes viz., NVSR-936, NVSR-938, NVSR-941, NVSR-950, NVSR-951, NVSR-942, NVSR-1002, NVSR-1003, NVSR-1005, NVSR-1048, NVSR-1111, NVSR-983, NVSR-1130, NVSR-1064, and GNR-3 were found moderately susceptible. Eleven genotypes viz., NVSR-939, NVSR-952, NVSR-997, NVSR-956, NVSR-1001, NVSR-1007, NVSR-1031, NVSR-1033, NVSR-1128, NVSR-964, and NVSR-1052 were found to be susceptible. Whereas, the susceptible checks GR-11 and TN-1 were found highly susceptible against bacterial blight of rice. Among the screened genotypes, NVSR-939 exhibited the highest disease intensity (48.60%) followed by NVSR-1128 (48.57%) and NVSR-952 (46.20%). In contrast, ISM had the lowest disease intensity (7.28%) followed by NVSR-1065 (8.20%) and NVSR-996 (8.60%), respectively. The international susceptible check TN-1 showed a disease intensity of 76.00 percent and the local check GR-11 showed 68.57 per cent, both indicating high susceptibility to bacterial blight of rice.

Abstract

Underutilized fruit crops encompass plant species traditionally utilized for various purposes such as food, fodder, fiber, oil, and their extensive medicinal attributes. Despite their multifaceted potential in ensuring food security, nutrition, health, income generation, and ecological benefits, these species remain underexplored. While commercially cultivated fruits like Mango, Banana, Papaya, Litchi, Guava, among others, dominate the market, wild edible fruits remain largely uncultivated and undomesticated. Many of these underutilized indigenous fruit crops serve as integral components of traditional medicine systems across India. Their value-added products present an opportunity for focused efforts to tap into both domestic and international markets. This overview primarily centers on elucidating the food, nutritional, and medicinal significance of these minor fruits. In India, prevalent underutilized fruits include Bael (Aegle marmelos), Jamun (Syzygium cumini), Karonda (Carissa carandas), Ber (Ziziphus mauritiana), Lasora (Cordia myxa L), Phalsa (Grewia subinaequalis), among others. Hence, this review paper primarily emphasizes the nutritional, therapeutic, and various other values associated with these diverse fruit crops.

Abstract

Climate change is expected to exert significant impacts on crop yields by altering temperatures and water availability. Mitigation and adaptation efforts aim to counteract these effects gradually while sustaining development. Effective strategies encompass various practices that fall into three main categories: crop and cropping system-based technologies, resource conservation-based technologies, and socio-economic and policy interventions. In the context of India, it is crucial to explore these measures and identify the most suitable strategies for combatting climate change. Crop and cropping system-based technologies involve the adoption of climate-resilient crop varieties and optimized planting practices. Utilizing drought-resistant seeds, implementing precision agriculture techniques, and adjusting planting calendars can enhance resilience to changing climatic conditions in India. Resource conservation-based technologies encompass sustainable water management and soil conservation practices. Implementing efficient irrigation methods, such as drip irrigation and rainwater harvesting, can help preserve precious water resources. Soil health improvement through organic farming, reduced tillage, and agroforestry can enhance soil fertility and mitigate climate-related risks. Socio-economic and policy interventions playa critical role in climate resilience. Promoting farmer education and awareness on climate-smart agriculture practices can empower rural communities to adapt effectively. Additionally, government policies that incentivize sustainable agriculture, provide insurance against climate-related crop losses, and support research and development of climate-resilient technologies are essential for long-term climate adaptation in India.

Abstract

Erratic and inadequate rainfall is one of the important factors for crop production under rainfed conditions. Crop grown as sole crop are found to be rather risky due to delayed monsoon accompanied with prolonged intermittent dry spells. A strategy for stabilizing production of dry-land crops through commonly recognized practice of intercropping of compatible crops is considered viable to overcome the situation. Mothbean and pearlmillet are important arid crop. So it is necessary to find out its intercropping proportion to resuce the risk of failure of sole crop. Therefore, an experiment was conducted at Dry Farming Research Station, Sardarkrushinagar Dantiwada Agricultural University, Radhanpur to evaluate of cropping system for rainfed agriculture in kharif season during 2010-11 to 2022-23. Significantly higher pearlmillet equivalent yield (3466 kg/ha) was recorded under Sole Mothbean which remained at par with pearl millet + moth bean (1:3) intercropping (3305 kg/ha).

Abstract

The district is located at a distance of around 430 kmfrom Srinagar and 235 kmfrom Kargil. The present study was conducted in the Changthang region of Leh District in UT Ladakh. The sample for the study was drawn from the Nyoma block of the Changthang region. The traditional food of Changthang people is based on animals, vegetables, and the cropping system of barley. Animal-based products (meat and dairy) are common. Most people eat dry yak and goat meat, which is sliced thinly and hung to dry after slaughter. By-products of livestock such as milk are used to make paneer, churpey (cottage cheese), butter (khakla maar), and ghee. Pastoral nomads consume only meat and milk from their livestock due to the absence of a cropping system, as they migrate in search of pasture for their livestock. During the winter, Changthang people sell livestock like goats, sheep, and yak in other parts of Leh. They face various challenges in life, especially regarding health and basic necessities, which impacts their social and economic life. Most people consume preserved products like dried meat and churpey. Traditionally, the agricultural system in the Changthang region was primarily for self-consumption. Krishi Vigyan scientists provide training on food preservation and value addition for milk products, vegetables, and barley, focusing on drying vegetables in a hygienic way without losing vitamins and minerals.

Abstract

As the population of India is increasing at avery fast rate; the land-holding size of farmers shrink at avery fast rate and agroforestry is the only way to optimize the farm productivity. The trees play an important role in fulfilling daily needs of people. The Eastern part of Uttar Pradesh in India is in great deficit of tree plantations on agriculture lands. Agroforestry is only way for growing trees on available lands in block/boundary plantations, thus, reducing pressure on forests for tree based needs in day-to-day life. As per latest report of FSI, 2021, only 9.23 % (6.18 % forest and 3.05 % Tree cover outside forests) area is covered with trees in the state of Uttar Pradesh. In Vindhyan region, total 15489782 trees were enumerated, where highest (2509795) number of trees were found in 121-150 cm girth class, followed by 2283850 trees in 151-180 cm girth class and 1996340 trees in 91-120 cm girth class Similarly, Eucalyptus tree possessed highest contribution (18.29%), followed by Mango(15.1%), Teak (14.34%) and Neem (13.83 %) .The smallest (629466) no. of trees were found in 271-300 cm followed by 756034 in 0-30 cm class. It clearly indicates that overall there is urgent need of time to plant these species indifferent agroforestry models to overcome wide demand supply gap of traditional tree species like, desi Mango, Neem, Teak, Eucalyptus, Mahua and Shisham. Similarly, new species, like Mahogany, Melia, Gamhar and Chironji may be planted in various agroforestry combinations in view of their great economic value. In recent past, Mahogany gave a good response in the region and 44358 no. of trees were found in 0-30 cm girth class in respective districts. Like Gamhar was also seen in some villages with 7747 no. of trees in 0-30 cm girth class in studied districts. The condition of Mahua planting is alarming as being a slow growing species, only 6798 no. of trees were found in 0-30 cm girth class. In new species, Melia dubia istaking good place, as 28646 trees were found in 0-30 cm class in villages. Chironji trees were rare in Mirzapur and Sonbhadra district and completely absent in Prayagraj district. In a total, only 4480 Chironji trees were recorded in the Vindhyan region. The girth class wise trees in Vindhyan region depicted that in 271-300 girth class, minimum number of trees were existing followed by 0-30 cm girth class and 31-60 cm class. This is clear that old trees were harvested at very fast rate for most of the species and less young plantations showed that these established and new tree species should be planted at fast rate in agroforestry so as to maintain their sustainable availability.

Abstract

This study explores the economic impact of land conversion on the agricultural sector in Central Luzon from 1981 to 2021, using the Cobb-Douglas production function as the analytical framework. Employing key econometric tools—such as the Augmented Dickey-Fuller (ADF) test for stationarity, Johansen cointegration for long-term relationships, and Ordinary Least Squares (OLS) regression—the analysis shows that all variables are stationary. Farm size is positively correlated with rice output, while labor use and the man-land ratio negatively affect production. The findings highlight the vital role rice production plays in the household income of Central Luzon, indicating that while it has contributed to modest but steady economic growth, land conversion has acted as an economic boon, promoting development opportunities in the region. The study concludes by urging policymakers to craft strategies that enhance agricultural productivity and ensure sustainable income for farmers, contributing to broader economic prosperity. Future research should examine the specific types of land being converted from agriculture, assess the long-term impacts on different crops, and consider how land conversion affects the region'soverall agricultural sustainability. This will provide a more comprehensive understanding of the broader implications of land use changes on Central Luzon'seconomy.

Abstract

Agriculture, specifically crop production, is a crucial driver of prosperity in the Philippines, contributing to economic growth, employing 36% of the workforce, and ensuring food security. Palay is Central Luzon'smost widely grown crop, making it the country'slargest producer. Crops like palay do not grow on their own; a variety of factors, such as arable land availability, urbanization, and agricultural mechanization influences them. Therefore, this study examines the effect of selected agricultural input on palay production in Central Luzon from 1970 to 2019, with CobbDouglas production function as its basis. The adopted methodology is the unit root test by the Augmented Dickey-Fuller (ADF) approach, a test for long-run relationship (Johansen cointegration), and the Ordinary Least Squares (OLS) multiple regression method. The study would like to knowhow the chosen input will affect the output of palay production in the area. The study indicates that the variables are stationary. Land use conversion and Agricultural mechanization show that it significantly affects palay production in the region. Considering that the area is well suited for crop production, the governing bodies should urgently establish and impose policies that cultivate agricultural development to support the country'sfood security and economic prosperity.

Abstract

The Western Ghats, a UNESCO World Heritage site in India, is renowned for its rich biodiversity and endemic flora, particularly its wild orchids. Wayanad, located within the Ghats, is a significant hotspot for orchid diversity, harboring a range of rare and ecologically valuable species. This study examines the diversity, distribution, and ecological roles of wild orchid species in Wayanad, with a focus on their contributions to habitat stability and biodiversity. Through a combination of field surveys and ecological assessments conducted in selected forested regions, we identified over 50 species of orchids, with a notable percentage being endemic to the Western Ghats. Many of these orchids have intricate relationships with pollinators and mycorrhizal fungi, which are crucial for their reproduction and survival, thus playing essential roles in sustaining local biodiversity.

Orchids serve as bioindicators of ecosystem health due to their sensitivity to habitat changes, and their presence reflects the ecological stability of Wayanad’sforest ecosystems. Additionally, they contribute to nutrient cycling and enhance forest dynamics through interactions with a wide array of pollinators, including bees, moths, and birds. However, habitat loss, climate change, and illegal collection pose significant threats to these orchids, with potential cascading effects on the ecosystem. Conservation efforts are thus urgently needed to protect these species, which hold both ecological and cultural significance.

Our findings underscore the importance of conserving Wayanad'swild orchids to maintain ecological balance and biodiversity in the Western Ghats. Effective conservation strategies, including habitat preservation, community awareness, and policy enforcement, are essential to safeguard these species. This study provides critical insights into the ecological roles of wild orchids and highlights the need for integrated conservation approaches that prioritize both species protection and ecosystem health.
