2022-12-10T11:44:36+00:00

The purpose of this study has been to determine the selection criteria for plant breeders using correlation and path analyses of the safflower plant. The experiment was carried out at the University of Ondokuz Mayıs, Faculty of Agriculture, Fields Crops Department during the season 2017-2019 under winter and summer growing seasons. A randomized complete block with three replications was adopted. The results of our study showed a strong positive significative correlation of seed yield per plant with head weight (0.916), head number (0.908), seed number (0.886), root dry weight (0.841), branch number (0.833), stem dry weight (0.783), plant height (0.704), thousand seed weight (0.485). Days to maturity (0.927), days to rosette (0.670), head number (0.402), stem dry weight (0.359), and head weight (0.343) had the most important positive direct effect on seed yield indicating that these characters will be effective in safflower breeding.

Investigations were carried out to study the effect of organic and bio-mulches in the cultivation of baby corn (Zea mays L.) at the Orchard, Department of Horticulture, Faculty of Agriculture, Annamalai University during 2000-2002. The experiment was laid out in a Randomized Block Design with eight treatments replicated thrice. The treatments consisted of application of four organic mulches viz., sugarcane trash mulch at 10 cm thickness, water hyacinth residue at 5 cm thickness, sawdust at 2 cm thickness and coir pith at 2 cm thickness and cultivation of three bio-mulches viz., coriander, mint and fenugreek. Significant effects due to the application of organic mulches and cultivation of bio-mulches were found on the weed control of baby corn. The highest response for plant characters was recorded due to the application of sugarcane trash at 10 cm thickness. It was closely followed by the application of coir pith at 2 cm thickness. Besides, spectacular effect on weed control was observed due to mulching treatments. The best weed control efficiency was recorded due the application of sugarcane trash at 10 cm thickness. This was followed by the application of coir pith at 2 cm thickness. Among the bio-mulches tried, satisfactory results were obtained by growing coriander for greens.

Hence, from the results of weed biometrics application of sugarcane trash at 10 cm thickness was found to be the best than the other mulching practices tried for baby corn.

The hemp (Cannabis sativa) used for this work were obtained in a farm at Ogbese in Owo Local Government of Ondo State Nigeria. They were prepared for use by decoating, sun drying and milling. The milled sample were subdivided into two portions, one portion was defatted and named as defatted sample using normal hexane while the other portion was left raw. The samples were powdered in willey mill 60 mesh sizes and stored in screw cap bottle at room temperature for further analysis. Proximate analysis, mineral, phytochemical and functional composition of hemp (Cannabis sativa) were examined. The mean values of various parameters for proximate composition, of both raw and defatted samples were moisture content (5.65+0.03) and (5.60+0.05), ash content (6.50+0.01) and (6.40+0.01), fiber content (18.85+0.20 and 16.05+0.12), fat content (30.43+0.03) and (15.60+0.15), crude protein (25.45+0.02) and (28.05+0.00) and finally carbohydrate (13.12+0.01) and (28.30+0.02) for both raw and defatted samples respectively. Mineral (mg/kg) includes Potassium (8.75+0,01), Calcium (18.60+0.35), Sodium (7.52+0.02), Magnesium (14.10+0.03), Zink (2.10+0,02), Lead (0.05+0,01). The macronutrients and micronutrients present in the study is required for optimal functioning of physiological and biochemical process in the body. The results of functional properties of Cannabis sativa seed flour with the mean value of the following parameters bulk density (20.05+0.01 g/ml), Water absorption capacity (35.15+0.12), Oil absorption capacity (25.01+0.12), Foaming capacity (5.05+0.01) and Emulsion capacity (20.00+0.01) respectively. The result of phytochemical screening revealed that Oxalate, saponin and alkaloid were moderately present in Cannabis sativa seed four, tannins was slightly present while phytate was highly present in Cannabis sativa seed flour suggesting that the Cannabis sativa is relatively save for consumption.

A comparative analysis of photosynthetic pigment elution efficiency by different organic solvents of varying concentrations on leaves of Tecoma stans (L.) Kunth

2023-03-05T10:24:23+00:00

Quantitative analysis of photosynthetic pigments using different organic solvents and different concentrations of the same was conducted on leaves of Tecoma stans. The organic solvents used were Acetone, Methanol, Chloroform, Ethanol and Butyl alcohol of 40 and 80 percentage concentrations. From the study it was understood that Methanol at 40% was the best eluent of chlorophyll-a, chlorophyll-b, total chlorophylls and carotenoids. Butyl alcohol at 80% was the weakest eluent of chlorophyll-a, chlorophyll-b and total chlorophylls; where as Methanol at 80% was giving minimum elution of carotenoids.

A study of phytosociological attributes of shrubs plant resources in nallamalais

2023-03-12T15:34:09+00:00

Biodiversity is essential for human survival and economic wellbeing and for the ecosystem function and stability.forest in India are considered as a source of livelihood for forest department people, as repository of rich biodiversity and source of timber for industries. Nallamalla, the study area of the present work is one of the 234 Centres of Plant Diversity of the World. Heavy biotic interference primarily pertaining to over-exploitation of wild plant resources is leading to alarming loss of species population in the study area.The present study is based on ramdom sampling method by quadrates in different vegetation types of Nallamalais & documents the diversity of shrubs plant resources of the forest.The total number of individuals TNI of shrubs in the study site was 606. The total abundance value for all the 37 shrubs is 210.22 which are average of 5.68.
