Variation in soil physical properties among different slopes in submontane region of Northern India
The present study was conducted at Kokowal, Majari, Jhunewal and Bhadiar sites located in Hoshiarpur district of Punjab, Northern India. The soil samples were collected from upper, middle and lower slope positions of each site and analysed for soil physical properties. Significantly higher soil organic carbon (SOC) was observed in Bhadiar compared to all other locations. The average SOC increased significantly with the lower slope positions. Among all the sites, the significantly lowest mean value of bulk density was observed at Kokowal (1.45 Mg/m3) and highest at Jhunewal (1.48 Mg/m3). Saturated hydraulic conductivity was significantly low on lower slope position than upper slope position irrespective of soil depth at all sites. At lower slope position significantly less infiltration rate was observed over the upper slope position. Soil moisture retention varied from 12.0 to 16.2, 14.7 to 16.9 and 16.3 to 17.9 percent for upper, middle and lower slope position respectively. The moisture content of soil profile increased with increase in soil depth irrespective of slope position. The total moisture storage was 20.0, 23.1 and 24.9 cm on upper, middle and lower slope position respectively.
Effect of irrigation regimes and tillage on grain yield and water productivity of summer mungbean in northwest India
Mungbean crop due to short duration and has a distinct advantage over other legumes to be grown in both summer and kharif season has a good potential to be used in the intensive cropping system. A field experiment was conducted at the research farm of the Department of Soil Science, Punjab Agricultural University, Ludhiana during summer seasons 2016, 2017 and 2019 to study the deep tillage and irrigation effects on water productivity of summer mungbean. Treatments included three irrigation regimes (I0.75, I0.50, and I0.25) in the main plots and two tillage systems (conventional tillage-CT and deep tillage-DT) in the subplots. Penetration resistance was observed to be lower in DT than CT throughout the depths of measurement. Root growth was measured at podding and least frequent irrigation regime I0.25 and DT increased root growth (root mass density) more so in the deeper layers (i.e. from 60-90 cm). Yield attributes were much influenced by deep tillage and effects were more pronounced in 2019. Profile moisture storage was about 3 cm higher in more irrigated regimes (I0.50 and I0.75). Increase in irrigation frequency increased the mean seasonal water use by the crop and it varied from (25.2 cm to 39.2 cm) during the three cropping seasons. It was also higher under DT in less and medium frequent regimes (I0.25 and I0.50) compared to CT. Grain yield was influenced by both irrigation and deep tillage. Medium irrigated I0.50 regime had maximum grain yield followed by I0.75 and I0.25 irrigation regimes. DT enhanced the mean grain yield over CT by 0.03 t/ha in 2016 and 0.06 t/ha in 2017 and 2019 respectively. An increase in irrigation frequency reduced mean water productivity and it varies from 3.57 kg/ha/mm to 2.00 kg/ha/mm; DT had a tendency to increase water productivity during the three cropping seasons.
ASSESSMENT AND OPTIMIZATION STUDY OF PLANT BASED VITAL NUTRACEUTICALS ON QUALITY CHARACTERISTICS OF PIZZA CHEESE
Milk and Milk products is an excellent option as a food delivery vehicle for vital ingredient as it carries many other health benefits. However, milk and milk products are poor source of omega 3 fatty acids and devoid of dietary fibre. Nowadays, consumers trend is towards westernized products with much emphasis on pizza cheese, therefore plant based key ingredients like flaxseed oil, algal oil as the source of omega 3 fatty acids and inulin as a dietary fibre were added in the form of emulsion and further dried encapsulated powder to provide more functionality to the consumers, keeping well the taste attributes. From the sensory studies, it could be concluded that incorporation levels of emulsion and encapsulated powder @ 6 and 3 per cent respectively, in the milk as well as in the curd during pizza cheese preparation were acceptable by the panelists. Furthermore, it was found that only 40per cent of nutraceuticals were retained in the pizza cheese, whereas a humongous i.e., 60 per cent were lost in the whey analyzing the samples. From this study, it was concluded that retained vital ingredients present in the pizza cheese were not up to the recommended level to provide appropriate health benefits. Hence, the pizza cheese (processed) is an alternative option to retain the expected vital ingredients to provide the health benefits.
STATUS AND DIMENSION OF RICE PRODUCTION IN MANIPUR -An analysis of the yield gap
A study on the status and dimension of rice production in Imphal West and Chandel district of Manipur shows that the state of Manipur particularly the valley districts contribute mainly in the production and productivity of rice as compare to the hill district. The analysis of the existing rice varieties about the production and productivity indicates the existence of yield gap across the improved varieties upto 17.84% in yield Gap-I, 12.56% in yield Gap-II in the valley districts and 19.66% in yield Gap-I and 17.58% in yield Gap-II in the hill districts due to the various technical, environmental, socio-economic and institutional problems and constraints. Interventions such as On-Farm Trial cum Testing, Front Line Demonstration, Scientific training, Seed Production, Field Day, Mobile Agro-Advisories, Method Demonstrations, Extension literatures, popular articles, Radio & TV Talks, improved farm mechanization, resource conservation technologies such as ICM, SRI, introduction of NANO urea, Drone application and climate resilient technologies and varietal diversification can minimize the yield gap of rice production and productivity scenario in the state of Manipur. Reviving and strengthening of irrigation infrastructures, effective implementation of Govt. schemes, financial inclusions along with sound agriculture state agricultural policy including the fertilizers delivery mechanisms can changed the socio-economic profile of the rice-growers and can ultimately fulfill or attain the self-reliant rice producing state.
Morphological and molecular-based differentiation of diverse seedlings of polyembryonic mango genotypes
Nucellar seedlings of polyembryonic varieties are utilized as rootstocks hence distinguishing nucellar from zygotic seedlings in the polyembryonic kernel is crucial for obtaining clonal rootstock material. The current study aimed to identify the origin of multiple seedlings in the polyembryonic Mango cultivars Vellaikulamban and Olour with monoembryonic reference Totapuri. Morphological studies on embryos’ position, fresh weight, length, and width of kernel embryos were recorded. Twelve markers were used to identify the origin of seedlings. The third position embryo in the polyembryonic kernels exhibited maximum fresh weight, length, and width followed by 4th and 2nd position embryos. However, the average embryos per kernel were maximum in Olour. Analysed PCR products were subjected to gene scan analysis and data was compared through the Neighbour Joining method. Eleven markers showed polymorphism in the differentiation of nucellar and zygotic seedlings. Based on the genetic dissimilarity, the genetically variant zygotic seedlings of polyembryonic genotypes (VK-3C, OL-3C, OL-4D, Tota-1) were grouped with monoembryonic maternal Totapuri (Tota-M) in the same cluster while those nucellar originated seedlings of Vellaikulamban and Olour were grouped with their respective maternal parent (VK-M, OL-M). The current study provides a basic understanding of prior seedling identification for the selection of clonal rootstock for propagation.
