“…Additionally, Sivakumar and Parvez [56] claimed in a paper that increased chemical use and tainted water from domestic waste caused a decline in coconut productivity. The wide sections of midland laterites and the Onattukara sandy plain, characterized by significant acid reactions and high levels of aluminum in soil solutions, as reported in an article (1) by Nair et al [57], severely limit coconut production.…”

Coconut Value Chain Analysis: A Systematic Review

In the past, Malaysia’s coconut sector faced several difficulties and upheavals related to the economy. However, as a result of the EU’s decision to oppose the cultivation of palm oil due to worries about forest clearing and environmental damage, the business has recently demonstrated enormous potential to be further grown and improved. Thus, this systematic review aimed to synthesize the challenges associated with the level of coconut production and its supply chain. Six electronic databases were searched for publication from 2013 to 2022 (i.e., a cumulative index to give an overview of the coconut value chain and the literature on the coconut supply chain via Scopus, the Web of Science, Google Scholar, Proquest, Science Direct, and Springer Link). Titles/abstracts and then full texts were screened independently. It was discovered that the factors contributing to the low production of coconuts and the difficulties in the coconut supply chain were categorized by some authors as severe or apparent factors, while others categorized these problems as technological, political, or socioeconomic factors, and yet others categorized them as inherent or environmental factors. Therefore, policymakers should introduce some policies such as subsidies, free tax for farmers, farm settlement schemes e.t.c that would encourage more citizens to be willing to go into coconut production. Policymakers also need to encourage scientists to carry out research on how these problems especially environmental factors will be tackled and try to recruit more extensionists.

“…India is the third-largest producer, accounting for 10.61 million metric tons of Coconut production annually (FAOSTAT 2022). In India, Coconut is grown under varying soil conditions (Subramanian et al 2018), and soil fertility plays a signi cant role in the growth, health, and productivity of Coconut palms (Issaka et al 2012;Chandrakala et al 2018;Nair et al 2018b). Soil fertility management and nutrient replenishment through applying chemical fertilizers or manures into elds is a common practice for improving the yield of Coconut (Nirukshan et al 2016).…”

“…Kerala's highly weathered and leached laterite and coastal sandy soils are generally de cient in K-bearing minerals(Rajasekharan et al 2014). Additionally, the poor cation exchange capacity of these soils also prevents the retention of K in the soils(Nair et al 2018b). Accordingly, all the soil types of Kerala under Coconut cultivation are considered de cient in K (Khan and Krishnakumar 2018).…”

“…A negative correlation between P and soil pH is observed in COD-growing soils, whereas a positive correlation between SAP and SAN is observed in CGD-growing soils. Such partial interrelationships between SAP and speci c soil parameters are kept in healthy and diseased palm-growing soils.Although monocots like Coconut require large amounts of Potassium(Malhotra et al 2017;Nair et al 2018b), their availability in soil depends on the nature and composition of the parent material from which the soil is developed(Graham and Fox 1971). K content in humid tropical Coconut elds is generally considered low to medium, whereas K is usually high in alluvial and black soils(Malhotra et al 2017).…”

Achieving sustainability in the productivity of crops has become essential in fulfilling the global sustainable developmental goals (SDG), which is impossible without continuous monitoring of the soil fertility status of traditional fields of specific crops worldwide. Palms and palm products, primarily Coconut palm, remain crucial to the world's sustainable rural, urban, and industrial development, especially in the tropics. Accordingly, the current study focuses on the soil fertility status of one of the most intensively Coconut-cultivated regions of South India, Kerala, concerning palm varieties, soil types, health conditions, and agroclimatic zones in two seasons. The data generated is valid globally for better comparison of the soil fertility issues of palm groves worldwide. Comparative account of soil fertility parameters such as soil pH, field water content (FWC), total organic carbon (TOC), soil available nitrogen (SAN), soil available phosphorus (SAP), and soil available potassium (SAK) of palm groves under 14 various soil series are discussed. The soil pH of most Coconut fields remains below seven; nitrogen and potassium are deficient in most fields, whereas carbon and phosphorus are high. The findings suggest the significance of continuous monitoring of NPK nutrient regimes and soil pH and carbon content in the fields for ensuring the sustainability of Coconut production and soil health maintenance in palm fields. Overall, the investigation stands as a model for monitoring crop fields worldwide to ensure food security and safety sustainability, especially in wet tropics, to overcome the climate crisis, and to achieve the targets of SDG 30.

“…Kerala has historically been a major producer of coconuts, accounting for around 68% of India's total production by the late 1970 s. Today, Kerala still contributes approximately 45% of India's coconut production, with most of the coconut cultivation concentrated in the southern Indian states, including Kerala and its neighboring states. However, coconut production in Kerala faces challenges [3], with one major threat being 'Root Wilt Disease'. Coastal regions with sandy soils and fertile interior places are ideal for coconut cultivation in Kerala, resulting in higher yields.…”

This study is intended to provide reliable and context-specific forecasting methodologies to support sustainable agricultural planning, resource allocation and policy formulation for the coconut industry in Kerala. It evaluates ARIMA models for Kerala’s coconut production area, production, and productivity. The ARIMA (0, 2, 1) model is preferred for the area of coconut production due to the precision of its residual statistics and the normality of its residual plots. The best fit for production and productivity is provided by the polynomial regression model of orders 3 and 9, respectively, which has lower MAPE, RMSE, and higher R2 values than ARIMA models. The hybrid model, which was created using the best-fitting polynomial and ARIMA models, provides a more accurate representation of the data than either the corresponding polynomial or ARIMA model due to its high R2 and low MAPE values. The hybrid models for area, production, and productivity have MAPE and R2 values of 1.78, 3.56, 3.01, and 0.9799, 0.9664, and 0.9395, respectively.
