Arecanut based cropping system –A way forward towards improvement of soil quality and profitability of the farming community
Soil quality play a key role in ecosystem functions for sustained crop productivity and promotion of plant health. In recent years, pronounced decline in soil health has been observed globally, resulting from non-adoption of appropriate agricultural practices and land-use approaches. Long-term sustainability of perennial crops like arecanut is threatened by soil degradation resulting from intensive land use practices in small and marginal holdings. Effective utilization of natural resources is encouraged by temporal and spatial arrangement of crops of different height, canopy patterns and root architecture in arecanut based cropping system (ABCS) become effective in improving productivity and also bringing gradual improvement in the soil properties by continuous addition of biomass into soil. Cropping system approach also helps to meet the diversified need of the farmers, increased profitability per unit area and mitigating the risk of mono-cropping. In this context, crop diversification in arecanut plantation with compatible subsidiary crops under six models were evaluated and results indicated significant improved of soil organic carbon (0.60% to 0.86 %), soil reaction (5.43-5.68) status over mono-cropping in the top layer of soil, along with a positive impact on the availability of essential macronutrients. ABCS involving crop combination of arecanut with black pepper, bay leaf, pineapple and colocasia contributed to higher chali equivalent yield (3,761 kg ha-1) from the subsidiary crops. ABCS not only providing additional income from different component crops, but also increased the chali yield even up to 50 % more than arecanut mono-cropping with highest net return per rupee of investment (4.21).
Marine-derived antioxidant fortification of chicken nuggets using Sargassum tenerrimum seaweed
The study envisages assessment of antioxidant activities and fat deteriorative parameters in Sargassum tenerrimum incorporated functional chicken nuggets. Significant reduction of cholesterol content by 32.60% proves its potential to develop low fat meat products. The enhanced antioxidant activities such a DPPH radical scavenging activity, ABST decolourization assay and Ferric acid reducing ability, and the lipid deteriorative parameters such as TBARS, FFA and PV of S. tenerrimum incorporated millet based (7% kodo millet + 3% refined wheat flour) chicken nuggets proves the synergistic impact of S. tenerrimum seaweed in kodo millet based chicken nuggets over the refined wheat flour incorporated nuggets. The results reveal that the S. tenerrimum is a candidate source of functional ingredient in chicken meat nuggets.
Production performance and egg quality characteristics of commercial layer chicken on dietary supplementation of Panchagavya and Phytogenic feed additive
The objective of this study was to evaluate the effect of dietary supplementation of panchagavya (PG) and phytogenic feed additive (turmeric) in commercial layers on production performance and egg quality characteristics. Four-hundred-day-old commercial layer chicks (BV-300) were randomly allotted into eight treatment groups with five replicates of ten chicks per replicate and reared upto 30 weeks of age. Dietary treatment groups consisted of T1 (control)-basal diet and T2 group were fed basal diet with oxytetracycline-50 ppm. The groups T3, T4 and T5 were fed basal diet supplemented with 5, 7.5 and 10 g/kg of panchagavya respectively. The other treatment groups T6, T7 and T8 were fed basal diet supplemented with turmeric 1 g/kg in combination with panchagavya at 5, 7.5 and 10 g/kg levels respectively. The egg production performance was recorded for the period from 19 to 30 weeks of age. Age at sexual maturity, age at 50 and 90 per cent egg production and feed consumption were recorded. The feed efficiency per dozen eggs, feed efficiency per kg egg mass, hen day and hen housed egg production were calculated. The egg quality characteristics such as egg weight, specific gravity, albumen index, haugh unit, yolk index, yolk colour and eggshell thickness were recorded. The results obtained from this study shown that the age at sexual maturity was significantly (P<0.05) earlier in all treatment groups except T7 (PG-7.5 g/kg and turmeric -1g/kg) group which attained sexual maturity in later age (129.40 days). No significant difference observed between the treatment groups for age at 50 and 90 per cent egg production. The results on hen day and hen housed egg production (per cent), feed consumption (g/bird/day) from 19 to 30 weeks of age showed no significant difference between the treatment groups. The overall feed efficiency per kg egg mass (19-30 weeks) showed significant (P<0.05) difference. Moreover, better feed efficiency per kg egg mass (2.35 and 2.37) was observed in T2 (antibiotic) group followed by T6 group (PG – 5 g/kg and turmeric -1 g/kg) as compared to other treatment groups. The results showed no significant effect on the egg quality characteristics such as shape index, albumen index, Haugh unit and yolk index of commercial layer chicken eggs between the treatment groups. Yolk colour (5.20) was significantly (P<0.01) higher in T6 (PG -5 g/kg and turmeric -1 g/kg) and T7 (PG -7.5 g/kg and turmeric -1 g/kg) groups as comparison with antibiotic fed group (4.50).
Response of ornamental plants under colored nets on vegetative, physiological, biochemical and quality parameters
The present research was conducted to find out the Effect of different colored shade nets on production and quality of various ornamental plants. The experiment consists of 25 treatments with three replications which were laid out in Factorial Randomized Complete Block Design. The treatments were combined with two factors as factor I with different colour shade nets are Green, White, Black, Red nets and Open condition and factor II comprises of different ornamental plants i.e., Pandanus veitchii, Epipremnum aureum, Sansevieria trifasciata, Aglaonema commutatum var. Redgold, Rhoeo spathacea were taken. The results revealed that the black shade net with combination of Epipremnum aureum had maximum plant height (338.87cm) and carotenoids 1.63mg/g was recorded. Red net with Rhoeo spathacea combination showed highest total leaf area (7098.24 cm2), photosynthesis rate (4.31), Crop growth rate (5.11 g m-2 day-1) and Relative Growth rate (5.55 g g-1 day-1) respectively. Plant spread and Dry matter production was found highest under red net and Pandanus combination. Green shadenet and Rhoeo combination showed maximum ascorbic acid (3.93 mg g-1) and leaf pH (6.32). Highest mean total chlorophyll (4.03 mg g-1) was observed under green net and Epipremnum and longest vase life (42.98 days) was reported under black net and Sansevieria. Black and red shade nets were shown to be more effective than other colour nets in enhancing the majority of plant characteristics. As a result, black or red nets can be utilised to substitute the commercially available green shade net for cut greens and potted plant production.
Influence Of Age At Slaughter On Fatty Acid Profile, Cholesterol Content And Tenderness Of Emu Meat
Sixteen emu birds were used to study the effect of the age at slaughter (15months and 18 months) on fatty acid composition, cholesterol content and tenderness of Emu meat. Fatty acid composition of emu meat was significantly affected by age at slaughter (P< 0.05). A highly significant difference (P< 0.01) was noticed between the Cholesterol content of the two age groups. Emus slaughtered at 18 months had more saturated fatty acids (P< 0.05) than those slaughtered at 15 months. The monounsaturated and polyunsaturated fatty acids were more in the younger age groups. Oleic acid (C18:1) was the predominant monounsaturated fatty acid and the polyunsaturated fatty acids such as the linoleic (C18:2) and linolenic (C18:3) were all significantly higher in the younger age groups. The attributes of tenderness like Fibre diameter (µm), Sarcomere length (µm), Myofibrillar Fragmentation index, Shear force value (kg/cm2) and Collagen content (mg/g) showed a highly significant difference between the two age groups.
