Divulging Satisfaction Levels of Residents for Household Waste Management through Vermicomposting at Dr. Rajendra Prasad Central Agricultural University: A Cross-sectional Exploration

Abstract: The reduction of household wastes has been a pressing issue and is a key element of waste management programme in India. The goal of present research was to evaluate the ongoing Household Waste Management Practices (HWMPs) of the University in managing the waste generated within it. To realize this goal, researchers conducted survey and investigative study with campus residents on HWMPs being followed in the campus. In this backdrop, the present study Original Research Article Kumar et al.; CJAST, 39(21): 48-55, 2020; Article no.CJAST.59426 49 was conducted with the following two objectives: To measure the Socio-Personal, Sociopsychological profiles and appraisal of on-site treatment of Household Waste of the Respondents with scientific parsimony and to quantify overall satisfaction level of the respondents as dependent variable. Out of total 750 residential quarters in the university from which 50 household heads of the quarters were selected through ‘probability simple random sampling’. In qualitative methods observation, interviews, open-ended surveys, focus groups and oral history were used. Closely 90 percent of respondents were well acquainted with the fact that collected household wastes are being converted into vermi-compost inside the university campus itself. More than one-fourth of the respondents addressed the problem of throwing garbage around the metallic dustbins. In order to generate statistical information quantitative survey of satisfaction level was done which revealed that more than 80 percent respondent showed their satisfaction for HWMPs. By applying the Pearson chi-square test it was revealed that satisfaction level of the respondents were inclined ‘towards satisfied to fully satisfied’ categories with the chi-square value, i.e. 24.72 was significant at 1% level with P-value of 0.001. So, it can be concluded that residents were satisfied from waste management programme and thus rejecting the framed null hypothesis. So, it can be inferred that this model of waste management may be recommended and replicated throughout the country and

Sulphur in Soils and Plants: An Overview

Abstract: In India food demand is increasingly doubled due to calorie consumption of fast growing population rate. For achieving and sustaining a high level of food production, especially in agriculture, soil must be regularly replenished with a balance of crop nutrients, like macronutrients, secondary nutrients and micronutrients. Sulphur (S) comes under secondary nutrients after nitrogen, phosphorus and potash (potassium) at number four as an essential nutrient. It exists in group 16 and period 3 with a molecular weight of 32 in the periodic table. Naturally S occurs as an element found in many minerals like iron pyrites, galena, gypsum and Epsom salts. In Igneous and Sedimentary rocks S occurs as sulphides and in soil it is also present as organic compounds also in industrial wastes, sea water as well as gaseous emission in the atmosphere. Under temperate conditions it assumes that more than 95% of total S in soil is present in the organic matter due to low decomposition rate. In plants, sulphur plays an important role in protein synthesis.

Genotype by Environment Interaction and Yield Stability of Potato Cultivars under Tropical Conditions

Abstract: Potato (Solanum tuberosum ssp. tuberosum) cultivars grown under tropical conditions exhibit comparatively poor yields compared to the temperate conditions, hence, there is need for stable cultivars with greater yields. The interactions of four cultivars with ten environments for 2 years under All India Coordinated Research Project (Potato) across the country for 2 harvesting stage (75 and 90 DAP) revealed that the cultivars were significantly different among themselves for Total Yield (TY) and Marketable Yield (MY) harvested at 75 and 90 DAP at seven and eight environments, respectively. The pooled analysis showed a significant difference for cultivar and environmental main effects for all traits, indicating the existence of cultivars genetic variability justified from the heterogeneity of environments. The significant effect of G×E interaction for TY and MY at 90 DAP, and a non significance for the same traits at 75 DAP clearly indicated that the prevailing environments during early crop stage were uniform as compared to its later harvesting stage. Partitioning of G×E interaction into linear and non linear components were highly significant for all traits, strongly suggesting the real differences in cultivars for regression over environmental means and the response of cultivars to environment was controlled genetically. The cultivar K. Pukhraj was proven as early bulking and stable cultivar for TY and MY at 75 DAP and predictable in nature, as against K. Khyati which was stable cultivar for TY and MY at 90 DAP across growing environments. Hence, K. Khyati, which recorded the highest TY (27.45 t ha) and MY (25.24 t ha) for harvesting at 75 DAP, and TY (31.28 t ha) and MY (28.19 t ha) at 90 DAP, can be recommended for tropical conditions.

Metabolic Bone Diseases of Captive Mammal, Reptile and Birds

Abstract: Metabolic Bone Disease (MBD) is the collective name given to a number of symptoms and problems commonly seen in captive mammals, birds and reptiles. The captive housed indoor animals are more susceptible to MBD; because of they have little access to UV light. Other names for MBD include Fibrous Osteodystrophy and Secondary Nutritional Hyperparathyroidism. All vertebrates need certain nutritional building blocks to form their skeletal systems. When they do not get sufficient nutrition in the proper proportions to form healthy bone structure, the animal suffer from metabolic bone disease. Symptoms of metabolic bone disease vary between species and individual animals, but includes soft short jaws, sprawl (inability to lift the body off the ground), anorexia, lameness, swollen limbs, bone fractures, curvature of the spine, tremors, small or deformed carapaces and death. Metabolic bone disease is particularly devastating for growing animals since this is the time in their lives when they are most actively forming their skeletal structure. This disease is very common especially in captive mammal, reptile and birds due to nutritional and improper husbandry practices. Therefore an attempt to made through this mini-review paper to educate reptile and birds owners about proper husbandry particularly in dietary needs and care management, because these all nutritional disorders seen in captive animals can be preventable.

Changes in land use pattern and factors responsible for variations in current fallow land in Bihar, India

Abstract: Endowment of fertile Gangetic alluvial soil and abundant water resources, particularly groundwater resources altogether constitute core components for development of agriculture in Bihar. Efforts have been made in this paper to analyze factors responsible for changes in land use pattern, especially increase in current fallows, shrinking net sown area and shifting of land for non-agricultural purposes in the state. A larger concentration of current fallow lands was accounted for in Gaya, Patna, Purnea, Munger, Jehanabad and Kishanganj districts. The rainfall and road length have significant impact on the level of current fallows. Erratic monsoon and labour scarcity during the study period of present century resulted in accumulation of current fallow lands. It was further observed that the non-agricultural use of land was identified as the dominant factor for changes in common lands as it affected the current fallows negatively. It is a challenging task for policy makers to maximize the income of farmers from a continuously declining in net sown area, deteriorating climatic conditions as well as labour scarce conditions, thereby resulting in aggregation of current fallows. In order to boost the production and enhance farmer’s income, it is necessary to discourage the rising tendency in current fallows or to bring current fallows under cultivation.
