The present study was extracted to address the adverse effects of cyclone on tall palms and recovery pattern of the tall coconut ecotypes. The trunk height was significantly higher in IC 599266 (9.28m) and lower in IC 599624 (8.22 m). The dense leaves were observed in IC 599264 with more number of scars in 1m (13.60 Nos. Longer leaflet was observed in IC 599664 (118.32cm) and shorter in IC 599265 (106.00) and the breadth of leaflet was broader in VPM4 (6.00cm) and leaner in IC599266 (4.53cm). The average length of inflorescence was 96.66 cm and 4 genotypes exceeded the grand mean which includes the two check varieties VPM 4 and ALR (CN)1. (CN)1. Positive correlation was observed between the number of leaves, number of female flowers, setting percent and the yield. The mean husked fruit weight was 464.62g with a deviation of 52.12g from the mean. Kernal thickness (2.40cm), Kernal weight (256.13g) and the copra content (137.70g) was the highest in IC 599264 compared to all the genotypes under study. The mean husked fruit weight was 464.62g with a deviation of 52.12g from the mean. Kernal thickness (2.40cm), Kernal weight (256.13g) and the copra content (137.70g) was the highest in IC 599264 compared to all the genotypes under study. The recovery response by this genotype indicates the adaptability to East Coast of Tamil Nadu.
Black gram [Vigna mungo (L.) Hepper] is a popular pulse crop in Asia that is severely affected by drought stress. It is known that the application of pink pigmented facultative methylotrophic bacteria (PPFM) enhances drought tolerance in agricultural crops. An experiment was conducted to explore the metabolomic profile associated with the foliar application of PPFM on drought stressed black gram plants. Spectrophotometric analysis revealed an increase in the osmolytes, fructan (6.50 mg/g) and proline (3.45 μM/g) in the leaf of PPFM treated plants under drought stress. Also, this treatment showed a high accumulation of antioxidants, carotenoids (45.63 μg/g) and tocopherol (9.67 μg/g) and significantly increased the grain yield. Gas chromatography-Mass Spectroscopy (GC-MS) analysis detected 34 metabolites in the PPFM treated leaves under drought stress of which the sugars, fructose, beta-D-allopyranose and beta-D-galactopyranose showed high accumulation. Nine metabolic pathways were found to be affected of which the glyoxylate and dicarboxylate metabolic pathway was most impacted. The results can facilitate further dissection of the mechanisms of drought tolerance contributed by PPFM.
Tamil Nadu is the fourth highest banana producing state in the country. In the past five years, there has been 32% increase in banana production in the state. One of the major constraints of traditional farming is low productivity due to lack of recommended package of practices and high yielding varieties. To replace this inconsistency of practices, Krishi Vigyan Kendra, Madurai conducted Front line demonstrations in the farmer’s field. Through frontline demonstration farmers were provided with all the basic inputs (improved practices). The technology adopted in his field is micronutrient spray @ 2% on 4th, 5th and 6th month’s interval from the date of planting. This resulted in higher yield than that obtained through the farmer’s practices. The average percentage of increase over farmers practice through this demonstration was recorded to be 11.9 percent during 2019-20 and 15.4 percent during 2020-21. The average extension gap in the improved practices was 15.0 q/ha during 2019-20 and 20.0 q/ha during 2020-21. The average technology gap in the improved technology was found to be 7.0 q/ha during 2019-20 and 5.0 q/ha during 2020-21.
Vegetables play a significant role in human nutrition, especially as sources of vitamins, minerals, dietary fiber and phytochemicals. The fraction of vegetable residues that remains after juice processing contains plenty of bioactive compounds. Hence the present investigation was carried out to standardize beetroot residue fortification as dietary fiber into beetroot Ready to Serve (RTS) beverages. Dietary fiber was extracted from the beetroot residues after juice extraction. The beetroot RTS beverages were fortified with different concentration levels (0.5%, 1% and 3%) of dietary fiber with the aim of increasing the dietary fiber intake. The overall acceptability score was 9.0 for control, 8.9 for T1 (0.5 % addition of dietary fiber), 8.0 for T2 (1.0 % addition of dietary fiber) and 7.5 for T3 (3.0 % addition of dietary fiber) samples respectively. The clarity and turbidity values increased as the dietary fiber content increased. RTS beverage fortified with 0.5 per cent dietary fiber was found to be best in their sensory characteristics and physical properties. The acidity of beetroot RTS (T1) was observed as 0.35 per cent, vitamin C content 18.76 mg/ 100 ml, reducing sugar content 3.68 %, total sugar content 8.67 % and total dietary fiber content 0.9 %. The standardized RTS beverages were packed in glass bottles and PET bottles and stored under refrigeration and storage studies performed. RTS beverages showed an increasing trend in pH, TSS, reducing sugar, total sugar and total dietary fiber whereas a decreasing trend in acidity and vitamin C content during storage. The increase in microbial load for 45 days of storage was negligible and safe for consumption. The fruits and vegetables waste could be effectively utilized as a functional ingredient in processed foods.
Polyamines, especially putrescine (Put), spermidine (Spd) and spermine (Spm) have been implicated in a wide range of biological processes, including growth, development and apoptosis. They are also associated with responses of plants to drought stress. A pot culture experiment was conducted to study the effect of exogenous application of polyamines – Spermine, Spermidine and Putrescine during water stress in blackgram KKM1. Water stress was imposed from 25 DAS followed by foliar application of Put (0.2 mM), Spd (0.2 mM), and Spm (0.2 mM) on 30 DAS. On 35 DAS, assessed the leaf samples for biochemical attributes - Proline, Chlorophyll, Soluble sugars, Total free aminoacid, RWC, Catalase and Peroxidase. The effect of exogenous polyamine application on growth attributes and yield attributes in blackgram under water stress were recorded. The results demonstrated that polyamines (Spd, Spm, Put) on exogenous application mitigated water stress in blackgram and treatment with spermidine had improved water stress tolerance and there is feasibility of polyamines serving as metabolic marker of water stress.
