The experiment was conducted in randomized block design with seven treatments and three replications with one control [chemical fertilizer (CF) alone] and six organic recycling options with combination of a native strain of Azospirillum sp. [L8(3)] isolated from the coconut rhizosphere, [100% RDN through cow dung slurry (CDS), 100% RDN through coconut leaf vermicompost (CLVC), 100% RDN through CDS + CLVC (1:1), 100% RDN through CDS + CLVC (1:1) + Azospirillum sp., 75% RDN through CDS + CLVC (1:1) + Azospirillum sp. and 50% RDN through CDS + CLVC (1:1) + Azospirillum sp.]. Basal application of 15 tonnes of dried cow dung, 400 kg lime and 90:30:24 kg NPK/ha were supplied irrespective of the treatments. The plants supplied with 100% RDN through CF and CDS + CLVC + Azospirillum sp. recorded the higher yield during the first year, followed by a yield decline in subsequent years which may be due to the nitrogen-induced reduction in soil pH as evident from the soil analysis. The significantly higher fresh fodder yield (126.9 tonnes/ha/year), dry matter yield (22.7 tonnes/ha/year), neutral and acid detergent fibres, crude protein and plant nutrient uptake were recorded by plants supplied with 75% RDN through CDS + CLVC + Azospirillum sp. Technological refinement by adding additional lime (400 kg/ha) during second and third years resulted in 24.59% higher yield. This system of recycling resulted 50% reduction in external physical inputs during the first year and 90% reduction in subsequent two years.Item Inorganic phosphorus fractions and phosphorus availability in long term fertilizer cum manurial trials under coconut cultivation(2023) Neenu, S.; Ravi Bhat; Selvamani, V.; Subramanian, P.Phosphorus is one of the major nutrients required for coconut production. 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.Item Integrated Nutrient Management for Combating Soil Pollution(2018) Neenu, S.; Ravi BhatItem Physical, Chemical and Functional Attributes of Neera Honey Infused Extrudates(2023) Pandiselvam, R.; Liya T. Joseph; Manikantan, M.R.; Anandu Chandra Khanashyam; Shameena Beegum; Ramesh, S.V.; Balasubramanian D.; Neenu, S.; Murali Gopal; Mathew, A.C.; Hebbar, K.B.Item Physical, Chemical and Functional Attributes of Neera Honey Infused Extrudates(2023) Pandiselvam, R.; Liya T. Joseph; Manikantan, M.R.; Anandu Chandra Khanashyam; Shameena Beegum; Ramesh, S.V.; D. Balasubramanian; Neenu, S.; Murali Gopal; Mathew, A.C.; Hebbar, K.B.Owing to the demand for the consumption of healthy extrudates, this study explored the infusion of neera (coconut inflorescence sap) honey in rice flour, corn flour and coconut milk residue blend-based extrudates. Neera honey, the concentrated coconut inflorescence sap, has numerous nutrients and a natural source of essential vitamins. Hence, the potential of neera honey as a biofortifying compound for the production of healthy extrudates was investigated. The rice and corn based extrudates supplemented with different concentration of neera honey have been prepared until the mix reaches 16 and 20% (w.b.) of feed moisture. Effect of addition of neera honey on the physical properties (expansion ratio, bulk density, specific length), functional properties (water absorption, water solubility, oil absorption), biochemical properties (total carbohydrates, total sugar, reducing sugar, phenolics, flavonoids, antioxidants), color parameters(L*, a*, b*), proximate compositions (moisture content, ash, protein, fat) and mineral profile of extrudates were recorded. Results suggest that addition of neera honey had a significant (p < 0.05) impact on all the physico-chemical parameters evaluated. Incorporation of neera honey (feed moisture 20%) resulted in extrudates with less expansion, high bulk density and specific length, having high sugar, protein, phenolics, vitamin C and antioxidant activity. The combination of 60% rice flour + 25% corn flour +15% coconut milk residue samples infused with neera honey upto 16% feed moisture was found suitable for the preparation of nutritious extrudates based on functional characterization and minerals evaluation.Item PLANT NUTRIENT ANALYSIS(2018) Selvamani, V.; Neenu, S.Item PLANT NUTRITION(2018) Neenu, S.; Karthika, K.S.Item Season and genotype effect on whole plant water use efficiency of coconut (Cocos nucifera L.) seedlings grown in a hydroponic system(2022) Hebbar, K.B.; S. Kannan; Neenu, S.; Abhin Sukumar. P; Ramesh, S.V.Item Sensorial, textural, and nutritional attributes of coconut sugar and cocoa solids based “bean-to-bar” dark chocolate(2022-01-01) Shameena Beegum; Pandiselvam, R.; Ramesh, S.V.; Sugatha, P.; Arifa Nooh; Neenu, S.; Alka Gupta; Eldho Varghese; D. Balasubramanian; Elain Apshara, S.; Manikantan, M.R.; Hebbar, K.BThe impacts of cocoa solids and coconut sugar on the sensory perception of bean-tobar dark chocolate were investigated with mixture design using response surface methodology. The maximum and minimum levels of cocoa nib, cocoa butter, and coconut sugar for the preparation of chocolate were 35–50%, 15–30%, and 20–35%, respectively. A suitable mathematical model was used to evaluate each response. Maximum and minimum levels of components caused a poor sensory acceptance of the resultant dark chocolate. The optimum level of independent variables, for the best set of responses, was 44.7% cocoa nib, 25.2% cocoa butter, and 30.2% coconut sugar, with a hedonic score of 8.28 for appearance, 8.64 for mouth feel, 8.71 for texture, 8.68 for taste, and 8.51 for overall acceptability, at a desirability of 0.86. The minimum time for grinding the chocolate mix was 24 hour, which was evident from the microscopic analysis of the chocolate mix. The optimized chocolate (70% dark) per 100 g constitutes 1.06 g moisture, 50.09 g crude fat, 10.37 g crude protein, 35.90 g carbohydrates, and 2.55 g ash content. The L, a, b values indicated a darker color and was stable under ambient condition with a hardness value of 59.52 N, which significantly decreased to 16.23 N within 10 min at ambient temperature (30 ± 2_C). The addition of coconut sugar along with cocoa solids incorporates polyphenols, flavonoids, antioxidant potential, and minerals into bean-to-bar dark chocolate and hence offers a commercial value and health potential for stakeholders.Item SOIL AND LEAF SAMPLE COLLECTION FROM COCONUT BASED CROPPING SYSTEM FOR ANALYSIS(2018) Selvamani, V.; Neenu, S.; Karthika, K.S.Item SOIL AND LEAF SAMPLING PROCEDURE IN ARECANUT AND COCOA(2018) Karthika, K.S.; Neenu, S.Item Sustainable agriculture: Need for Soil testing(2018) Karthika, K.S.; Neenu, S.; Hemalatha, B.
