A total of 90 coconut farmers participated in the adoption of ICAR-CPCRI technology to produce West Coast Tall (WCT) coconut seedlings that are resistant/tolerant to the root (wilt) disease at the community level. Partners included extension agents, coconut producers' societies (CPS) and clusters, women self-help groups (WSHGs), and agricultural labor organizations. The characteristics of technologies that are suggested for adoption in root (wilt) disease-aﬀected tracts, such as the scientific management of young coconut trees and the production of high-quality seedlings through community nurseries, challenge the idea of adoption. There are a lot of variances in the homestead gardens' marginal holdings, including expertise, the use of technology, and access to advisory services. Government agencies provided the majority of the seedlings and extension advisory services, emphasizing the necessity for FPO-based or private extension in the coconut growing industry. The coconut farmers' understanding has significantly improved as a result of the participatory interventions for managing seedlings. The participatory demonstration and community farm school (CFS) strategy is discussed in the paper as a way for homesteads to manage juvenile coconuts while integrating new ideas and fostering cross and reciprocal learning. Refining the current extension approach requires integrating new knowledge about the characteristics of seedling growth, future economic performance, and social evaluation of choices of technological, individual, and skill-oriented interventions in risk-prone areas with debilitating root (wilt) disease.","PeriodicalId":36468,"journal":{"name":"Journal of Plantation Crops","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139201165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The information about the fate of native and applied phosphorus in soil is essential for better management of the nutrient. The changes on inorganic P fractions and P availability in soil after 43 years of coconut cultivation were studied from a long term fertilizer cum manurial experiment at CPCRI, Kasaragod. There were 6 treatments viz. tillage with organic and inorganic fertilizer, tillage with inorganic fertilizer, inorganic fertilizers with basin forking, tillage alone, herbicide application without tillage and fertilizer and the control. Soil samples were taken at two depths (0-30 and 30-60 cm) from coconut basin for analysis. Phosphorus was fractionated into Easily Soluble P (ES-P), Aluminium P (AI-P), Iron P (Fe-P), Calcium P (Ca-P) and Reductant Soluble P (RS-P) through sequential extraction. The dominant phosphorus fraction in the coconut basin at 0-30 cm depth was Ca-P and the trend is as follows: Ca-P> Fe-P> RS-P>Al-P>ES-P. However, at 30-60 cm depth, Fe-P became the dominant fraction and the trend is Fe-P>Ca-P>RS-P>Al-P>ES-P. Long-term phosphorus fertilization would facilitate the accumulation of soil Ca-P, and thus improve soil P availability. In the interspaces, Fe-P was the dominating fraction in both the depths followed by Ca-P and RS-P. The diﬀerence in P fractions in fertilized and non-fertilized plots clearly showed that the fertilized plots have high content of all the inorganic phosphorus fractions in both the depths. Application of mineral P along with forking in basin showed a high concentration of all the inorganic P fractions compared to other fertilizer applied treatments.","PeriodicalId":36468,"journal":{"name":"Journal of Plantation Crops","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139204041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coconut is a victim of the catastrophes of climate change events like high temperature, excessive or deficit rainfall and increased atmospheric CO2 concentration. Coconut plantations in the state are hit by several pests and diseases, some of which are lethal, fatal and are debilitating in nature. An analysis of Strength, Weakness, Opportunities and Threats (SWOT) for the prospects of coconut cultivation in the state revealed that edaphic and climatic factors, less labour requirement compared to other field crops of the state and access to technologies remain the great strength, while tropical cyclones hitting coastal districts of the state, failure of monsoon, wide fluctuations in copra price, lack of producer-centric market intelligence are the striking weakness for coconut cultivation. Improved varieties and hybrids with desired traits, establishment of processing industries, international cargo terminals to tap export market and crop insurance scheme in the event of climatic aberrations, remain the major opportunities while declining soil fertility, debilitating pests and dreadful diseases and poor scientific management owing to the fragmented land holdings are the major threats of coconut cultivation in the state of Tamil Nadu.","PeriodicalId":36468,"journal":{"name":"Journal of Plantation Crops","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139199477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The plant is highly susceptible to both abiotic and biotic stresses. Despite the fact that several studies focusing on stress in cardamom have been conducted; a molecular analysis at the cellular level has not been reported. This study highlights the molecular response of homogenous population of cardamom cell suspension following the temperature and drought stresses for a short period of time (20 mins). Temperature stress at 30, 35, and 40°C caused a significant increase in the transient expression of genes, sHSP 17.8 and sHSP 17.9, which are molecular chaperones involved in protein folding coping with the heat stress response of plants. Drought stress with various concentrations of PEG 6000 has demonstrated only a little increase in the expression of transcription factors, WRKY 35 and WRKY 71. The study implies that sHSP 17.8 and sHSP 17.9 play a crucial role during heat stress, which is a major limiting factor for the cultivation of cardamom in lower altitudes where atmospheric temperature is usually high. But WRKY 35 and WRKY 71 genes are found not to have a high impact at the cellular level in response to drought stress in cardamom when it is exposed to a brief duration of drought. Understanding the molecular mechanism underlying abiotic stress response in cardamom will aid in developing elite varieties adaptable to lower altitudes and to cope with the frequent climatic variations.","PeriodicalId":36468,"journal":{"name":"Journal of Plantation Crops","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139316239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
