Demand for unconventional potherbs is increasing and known medicinal values or high content of Vitamin A or protein or Vitamin C will help jute to be equally popular as cheap sources of these. Walking on the paths of age-old belief on utilization of Jute as pat shak or potherbs (plant parts like leaves, flowers, stems, etc, that can be used in cooking or seasoning and flavouring) in some confined areas of India, the present study was undertaken with five varieties each of oilitorius and capsularis grown in teaching Farm Mondouri, BCKV in Randomised Block Design (RBD) with four replications during 2018- 2019 (4 rows of 4 m each) following recommended agronomic practices. Planting was done in first week of april month and were harvested after one month. Biomass traits like leaf length (cm), number of leaves per plant, leaf width (cm), petiole length(cm),  plant height (cm), weight per plant (gm) were recorded along with an estimation of Vitamin A, Vitamin C and protein content in the leaves. In olitorius heritability was moderately high in all the traits except a number of leaves along with moderate Genetic Advance as per cent of Mean (GAM) for Leaf length. Fresh weight indicates that this may be due to additive gene effects and selection for these types of traits may be always rewarding.  In capsularis heritability was moderately high for all traits except for the leaf length along with moderate GAM for petiole length and fresh weight indicates that this may be due to additive gene effects and selection for these types of traits may be rewarding. JRO 524 recorded high biomass yield along with high content of vitamin A (6950 IU (approximately 40 % of carrot) can serve as a cheap source of Vitamin A in the northeast provinces where it can be successfully taken as a vegetable as it happens to be one among the twenty-five popularly cultivated leafy vegetables (shaks) in West Bengal. Young jute leaves are flavorful and tender are rich in betacarotene, iron, calcium, and Vitamin C.  Criteria of selection for improvement of yield can be taken in terms of wt g per 10 plants as suggested in capsularis and both wt of leaves and petiole size and no of leaves in case of olitorius. Also it can be stated that the traits like no of leaves and Leaf length are more affected by environmental variations in case of olitorius and the trait like plant height in case of capsularis. JRO 524 recorded high biomass yield along with high content of vItamin A (6950 IU approximately 40 % of carrot) can serve as a cheap source of Vitamin A in the northeast provinces where it can be successfully taken as a vegetable.

In the modern high intensity aquaculture, probiotics offer an encouraging substitute to chemicals and antibiotics, one such important application of probiotics is their use as growth promoters, in addition to health and water quality management. On the same background, the study was carried to evaluate the effect of dietary incorporation of probiotic - Bacillus subtilis on the growth performance of grass carp (Ctenopharyngodon idella).The probiotic - Bacillus subtilis was mixed with the basal diet (Protein 32%) in three different concentrations (0.5, 1.0 and 1.5 % designated as T1, T2, and T3). The basal feed with no probiotic was used as control (T0). The impact was recorded for a period of 60 days. Feeding was done twice a day at the rate of 5% of their body weight. Growth performance was evaluated through estimation of weight gain, feed Conversion Ratio (FCR), protein Efficiency Ratio (PER), specific growth rate (SGR) and feed efficiency ratio (FER). It was observed that the probiotic Bacillussubtilis fed at 1.5% significantly improved the growth performance of the fish Ctenopharyngodon idella showing the highest growth rate followed by 1% and 0.5% probiotic fed diets.

Priya Chugh, Pushp Sharma

Current Journal of Applied Science and Technology, Page 38-47
DOI: 10.9734/cjast/2021/v40i1531412

Aims: To find the relationship between the non-destructive and destructive methods for the evaluation of photosynthetic pigments under field condition concerning heat stress conditions.

Study Design:  The crop was sown in factorial randomized block design in three replication.

Place and Duration of Study: The experiment was conducted during the (2016-2018) rabi crop season for two years. The crop was sown under timely and late sown condition in the research farm of Department of Plant Breeding and Genetics, Punjab Agricultural University, Ludhiana

Methodology: In the present investigation forty-nine advanced breeding lines of Indian mustard were sown under two planting conditions. The data recorded for photosynthetic pigments by calorimetric method by non-destructive methods at three crop stages i.e vegetative, flowering and siliquing.  The relationship between these parameters was carried out by correlation and regression analysis.

Results: Regression analysis indicated a non-linear relationship at vegetative stage under both sowing conditions, but at flowering stage, slope of the relationship increased with increasing SPAD and a linear relationship was observed (R2= 0.0362) as compared to vegetative stage. A significant and strong correlation was observed between total chlorophyll (siliquing stage) and SPAD value (flowering stage) in timely sown crop. Positive correlation existed between SPAD value and total chlorophyll at flowering stage and carotenoid content at siliquing stage.

Conclusion: The variation in the SPAD value and chlorophyll value is strongly related with the species, distribution of chlorophyll in leaf and hence chloroplast also. The lower value of regression coefficient and insignificant values of correlation might due to non-destructive SPAD values under field condition and sampling for calorimetric estimations.

DOI: 10.9734/cjast/2021/v40i1531414

The goal of this research is to develop captopril mouth dissolving films and evaluate the impact of various formulation factors on the physical and mechanical properties of the films, as well as drug release behaviour. In different grades, hydroxypropyl methyl cellulose (HPMC E15 and K4M) was employed as the film forming polymer. Formulation disintegration times were determined to be in the range of (52 2.5 to 125.6 2.02 s). Formula F2 had the fastest disintegration time in vitro (52 2.5 s) and was determined to be acceptable for film production with ideal physicochemical qualities, faster disintegration, and optimal in vitro release. It may be concluded that the solvent casting approach can be used to make captopril mouth dissolving films with a higher dissolution rate and greater patient compliance.

The UN Sustainability Goals emphasise on use of renewable sources of energy viz wind, solar, hydro power, biomass etc which are increasingly becoming important in the global energy mix. India with a 900 GW potential, aims to have 175 GW by 2022 and about 40% of total power production from renewable sources by 2030 with solar source contributing the most (83 %). Solar energy is the most fundamental renewable energy resource with many agricultural applications. The abundance of solar energy makes it suitable for electricity and thermal applications and hence can be used in agriculture in photovoltaic electricity generation, powering irrigation, crop and grain drying, pesticide application, green house heating and ventilation, cold storages etc. North western Himalayan regions are energy-poor with high energy requirements. Low ambient temperature, high Global Horizontal Irradiance (GHI) and Direct Net Irradiance (DNI) of 4.8-6.43 kWh per square metre per day indicate huge solar potential, higher solar photovoltaic electricity and solar thermal production efficiency. Solar energy can replace or supplement conventional sources used for domestic and agricultural applications in the region. However, the use of solar energy is limited by policy and regulatory obstacles, financial obstacles, land availability constraints and low PV conversion efficiency. Hence a robust policy, financial measures and technological refinement are needed to remove the bottlenecks. In this paper, attempts have been made to discuss solar energy use in agriculture, scope in the north western Himalayan region of India and future recommended strategies.
