“…Moreover, the increased availability of potash in the soil under the said integrated manuring practice also might have caused production of more female flowers in the palm in littoral sand. Similar results are in line with the findings of Sahoo et al [11] and Bhalerao et al [9].…”

“…The practice of integrated nutrient management had also shown a significant effect by increasing the production of inflorescences (12.36/palm/year) in treatment of green manuring + bio fertilizers + organic recycling + soil test based nutrients (chemical fertilizers) application as against the minimum number (11.21/palm/year) in green manuring + bio fertilizers + organic recycling + FYM. The more availability of nitrogen and potassium in littoral sand under the above integrated manuring practice might have induced the production of more inflorescences in the palm [8,9].…”

An experiment was carried out in a 38 years old coconut plantation of Sakhigopal Local Tall variety at All India Coordinated Research Project on palms, Konark (OUAT) during July 2017 to June 2019. The treatments comprised of three cropping system and three integrated nutrient management practices. The experiment was laid out in a Split Plot Design with three replications. The studies revealed that adoption of cropping system of coconut + sapota + pineapple with application of green manuring + biofertilizers + organic recycling + soil test based nutrients NPK (chemical fertilizers) application significantly increase the number of female flowers (245.83/palm/year), nut yield (65.21/palms/year), weight of whole nut (1206.54 g), weight of dehusked nut (603.01 g), kernel weight (293.41 g) and copra weight (168.33 g). Similarly minimum number of female flowers, nut yield, kernel weight and copra weight were recorded in treatment combination of monocrop of coconut with green manuring + biofertilizers + organic recycling. The study indicated that cropping coconut + sapota + pineapple cropping system with organic and soil test based nutrients NPK are suitable for better growth and development of coconut.

“…Weight of the sample was on par with inorganic method denoting the effect of organic treatment in maintaining the quantitative parameter of the samples. The increase in the availability of potassium, nitrogen, and phosphorus in the soil under the integrated nutrient management system might have induced the weight of dehusked coconut (Bhalerao et al, 2021; Karna et al, 2022). A similar observation was reported by Asha Monicka et al (2017) on the weight of dehusked coconuts where the weights of the nut ranged from 0.180 to 0.725 kg.…”

Coconut husk is widely used as a source of natural fibers in the tropics. Dehusking and fiber extraction are some of the important unit operations in coir manufacturing. For the development of an efficient and economically viable fiber extraction machine, the engineering properties of conventional and organically grown coconuts were evaluated. Selected engineering properties of whole coconut were investigated. The average true density and bulk density were in the range of 414.63 ± 111.85 to 529.28 ± 123.02 and 161.66 ± 24.41 to 212.23 ± 18.96 kg/m3, respectively. Along with whole coconuts, engineering properties of husk (weight, moisture content, and husk thickness), shell (weight, thickness, bulk density, and moisture content), and kernel parameters (weight, thickness, and moisture content) were also evaluated. The application of organic treatment (T4) exhibited substantial impacts, leading to a higher coconut weight (1.354 kg) as compared to conventional practices (T5), and increased dimensions (158.599 mm diameter and 205.000 mm height) and improved bulk density (190.97 kg/m3) in comparison to other organic treatments. In deshelled coconuts, T4 showcased a higher shell weight (175.667 g) and shell thickness (4.767 mm). The kernel parameters of T4 displayed enhancements, featuring a kernel weight of 314.334 g and a thickness of 11.774 mm. Although the study could not find any correlation between the farming practices and engineering characteristics of coconut fruit, the data presented herein could be utilized for the design and improvisation of efficient fiber extraction machines.Practical ApplicationsDeveloping countries are exploring the possibilities of implementation of organic farming for the production of agro products. Implementation of organic farming not only affects yield but may also change the engineering properties and nutritional characteristics of products. Understanding the engineering properties of food products grown under organic conditions is important for the modification of the design in the existing machineries and/or development of new food processing equipments.

“…This is remarkably higher than the 100 nuts per palm per year attained with the recommended inorganic fertilizer application in the coconut monocropping scenario (T 4 ) during the period from 2016 to 2020. The integration of 50% RDF and 50% organic fertilizers is crucial in enhancing coconut nut yield [20][21][22].…”

“…In contrast, the monocropping of coconut with the recommended dose of fertilizer application documented the lowest net income of 2549.86 USD per hectare per year. This balanced approach provides a Treatment 2 (T 2 ), which includes nutrient management with 50% inorganic fertilizer and 50% organic nutrient management, yielded the highest gross income [20,21] of 7724.45 USD per hectare per year (Table 5). This was closely followed by T 3 , which represents 100% organic nutrient management, including organic recycling with vermicompost, vermiwash, biofertilizer, in situ green manuring, green leaf manuring (Gliricidia leaves), composted coir pith husk incorporation (once in 3 years) and mulching with coconut leaves, yielding a net income of 6940.00 USD per hectare per year.…”

The study highlights the importance of integrating organic resources, such as vermicompost and biofertilizers with inorganic fertilizers to sustain coconut yields and manage costs. The experimental trial was conducted from 2016 to 2020 in a 47-year-old East Coast Tall coconut garden at Coconut Research Station in South India. The research evaluated four nutrient management treatments viz., T1 (75% Recommended Dose of Fertilizer (RDF) + 25% N organic), T2 (50% RDF + 50% N organic), T3 (100% N organic) and a control (100% RDF). Intercrops included black pepper (Piper nigrum), banana (Musa acuminata) and cocoa (Theobroma cacao). Organic manure significantly improved soil physical properties, water retention and overall soil health. The T2 treatment achieved the highest yields for coconut, cocoa, banana and black pepper. The added soil health parameters supported to these findings, with T2 showing the highest fungal (15.27 × 103 cfu/g of soil) and bacterial populations (17.25 × 105 cfu/g of soil), along with a significant earthworm population (26/m2), indicating enhanced soil ecosystem health. Additionally, soil moisture content was highest under T3 (100% organic) across various depths, followed by T2, highlighting the critical role of organic matter in improving soil moisture conservation. The economic feasibility analysis, including a net present value (NPV), benefit/cost ratio (B/C ratio) and an internal rate of return (IRR), revealed T2 to be the most economically viable nutrient management strategy. This study highlights the economic benefits of intercropping coconuts using an integrated nutrient management (INM) approach, demonstrating its superiority over traditional monocropping practices.
