Moisture Retention Capacity

A field experiment lasting 9 years was initiated in 1987 to study the effect of integrated nutrient management involving incorporation of wheat straw (WS) or farmyard manure (FYM) alone or in combination with inorganic fertilizer on a fine loamy mixed hyperthermic udic Ustochrept. Soil physical properties and the productivity of a rice–lentil cropping sequence were examined in a dry land farming system.At the end of the ninth cropping season, addition of organic materials had increased organic carbon, aggregate stability, moisture retention capacity and infiltration rate of the surface soil while reducing the bulk density. Application of inorganic fertilizer alone decreased the stability of macro aggregates and moisture retention capacity but increased the bulk density values. Treatment effects on moisture retentivity were more pronounced in the higher (0·3–1·5 MPa) suction range. During the first six experimental years, sole application of inorganic fertilizers produced 10–17% higher grain yield of rice, compared to sole application of organic sources or combined organic and inorganic sources. Annual applications of wheat straw and farmyard manure gave higher grain yields of rice from the seventh year onwards. Grain yields of lentil were higher with organic sources either alone or combined with inorganic nutrients.

Aims: To identify the stable genotypes across the seasons for different yield and its contributing traits. Study Design: Field experimental design was used Place and Duration of Study: The experiment was conducted in different seasons during 2017-19 at Department of Sericulture, University of Agricultural Sciences, GKVK, Bangalore. Methodology: The present study comprised of six mulberry genotypes viz., MI-012, MI-79, MI-21, MI-139, MI-516, ME-05 and two popular check varieties V1 and M5. Results: The mean squares due to seasons was significant for total shoot length (cm), number of leaves per plant, leaf yield per plant (g), ten fresh leaf weight (g), leaf moisture content (%) at harvest, leaf moisture retention capacity (%) at 6 and 9 hrs after harvest. Analysis of variance indicated high significance of mean sum of squares due to season for number of branches per plant, number of leaves per plant, leaf yield per plant, single leaf area, moisture content and moisture retention capacity at 6 and 9 hrs after harvest of leaf. Further, it could be observed that variance due to seasons (linear) were highly significant for number of branches per plant, total shoot length, number of leaves per plant, ten fresh leaf weight, leaf yield per plant, single leaf area, moisture content and moisture retention capacity at 6 and 9 hrs after harvest of leaf. Whereas, variance due to G х S (linear) was non significant for shoot height, internodal distance, number of leaves per plant, ten fresh leaf weight, leaf yield per plant, moisture content and moisture retention capacity at 6 and 9 hrs after harvest of leaf. Variance due to pooled deviation was highly significant for shoot height, number of branches per plant, total shoot length, internodal distance, number of leaves per plant, ten fresh leaf weight, single leaf area, moisture content and moisture retention capacity at 6 and 9 hrs after harvest of leaf. Whereas, variance due to pooled deviation was non significant for leaf yield per plant.

In the present investigation a study was conducted to prepare fruit leathers from two different fruit pulps i.e. papaya and apple in various proportions. Further study was carried out in order to evaluate the vitamin C retention of prepared leathers at different temperatures such as 55°C, 65°C and 75°C. All fruit leathers were then analyzed for their organoleptic characteristics such as color, flavor, taste, appearance and overall acceptability during storage period. A study was also carried out to evaluate the moisture retention in storage of the prepared leathers in different packaging materials such as LDPE, HDPE, aluminum foil and PET jar. The results revealed that the fruit leathers dried at 65°C shown highest vitamin-C retention with better retention of sensory properties. All leathers remained unchanged during storage period but the leather stored in aluminum foil has shown a remarkable ranking as compared to others during storage period. LDPE package has shown greater moisture fluctuation, while aluminum foil shown significant moisture retention during storage. It was also observed during the study that all fruit leathers had identical color, flavor and appearance which cannot be compared with one another.

Retention Parameters

A combination of field and laboratory procedures was used to estimate moisture-retention parameters of four coarse-textured soil series in southern Alberta. In situ field capacity moisture content was substantially higher than estimates based on conventional laboratory methods, resulting in significant underestimation of total available moisture. Moisture-retention capacity of all four soil series was found to be adequate for irrigation development. Empirical equations were developed to estimate the upper and lower limits of moisture retention on the basis of particle-size distribution, as determined by the Bouyoucos hydrometer method. Five alternative empirical methods were also evaluated for use in predicting moisture-retention parameters of coarse-textured soils. Equations presented by Rawls et al. (1982) were found to have the best relationship with southern Alberta data for both field capacity and wilting point. Key words: Coarse-textured soils, moisture-retention parameters, particle-size distribution, empirical models, irrigation suitability

pH-sensitive hydrogels based on chitosan-graft-poly(acrylamide-co-sodium acrylate) were synthesized via radical polymerization in solution. Ammonium persulfate was used as initiator, and various amounts of hexamine were used as a cross-linking agent. The structure of obtained hydrogels was characterized by Fourier transform infrared spectroscopy. Moisture-absorbing power of hydrogels in buffer solution with various pH value (pH = 1.65; 4.01; 12.43) was investigated. It is turned out that such a copolymers have a high moisture retention capacity (swelling index attains the value 1100%) and are capable for reusing, that makes it possible to apply the hydrogels in different areas.
