Research Notes: Influence of cropping system on seed yield, seed quality and other developmental traits and its implications on ideotype required in soybean for intercropping in maize

Generally , in India and particularly in the hilly region of the country, due to small holdings , farmers usually follow intercropping system for an assured and stabilized production. This consideration becomes more important in the light of recent comments of Baker (1975) about the unac cep tability of agricultural research on soybean with monoculture system, by the farmers in West Africa where intercropping is the general practice . This raises the question concerning development of ideotypes and their suitability for intercropping

Analyzing uncertainties in lake water: A review

ABSTRACT A lake may be defined as an enclosed body of water (usually freshwater) totally surrounded by land and with no direct access to the sea. Lakes are sometime subjected to wastewater discharges originating from different sources. Chemicals such as nitrogen, phosphorus and carbon in certain concentration might distort and disrupt aquatic ecosystem. Eutrophication of inland water bodies has become synonymous with the deterioration of water quality, which interferes with most of its beneficial uses. Now a day's many human activities creates the pollution in and around the water body, due to which natural status of lakes may come in the danger zone of water pollution. The quality of water usually is described according to its physical, chemical and biological characteristics. Rapid industrialization and indiscriminate use of chemical fertilizers and pesticides in agriculture are causing heavy and varied pollution in aquatic environment leading to deterioration of water quality and depletion of aquatic biota. Due to the use of contaminated water, human population suffers from water borne diseases. It is therefore necessary to check the water quality at regular intervals of time. This review paper gives a brief overview about lake, its classification and the various factors affecting its water quality. Moreover problem of eutrophication is also discussed in detail. Various parameters required for analyzing water quality along with water quality index are also discussed

ABSTRACT Heavy metals are inadvertently released during manufacture of various industrial products. They are serious pollutants due to their toxicity, persistence and bioaccumulation problems. Microorganisms have the potential to alter the reactivity and mobility of metals and thus facilitating the use of bioremediation as a form of treatment for metal contaminated soils. Utilizing microbes for bioremediation possesses various merits such as their natural occurrence, cheap production, easy availability and high selectivity in terms of removal and recovery of specific metals. This paper summarizes the general processes of bioremediation within the soil environment. The effect of environmental factors which governs the rate of biodegradation is addressed together with limitations and potential of ex situ and in situ bioremediation

A Review on Recent Trends and Future Developments in Electrochemical Sensing

Electrochemical methods and devices have ignited prodigious interest for sensing and monitoring. The greatest challenge for science is far from meeting the expectations of consumers. Electrodes made of two-dimensional (2D) materials such as graphene, metal organic frameworks, MXene and transition metal dichalcogenides as well as alternative electrochemical sensing methods offer potential to improve selectivity, sensitivity, detection limit, and response time. Moreover, these developments have accelerated the development of wearable and point-of-care electrochemical sensors, opening new possibilities and pathways for their applications. This review presents a critical discussion of the recent developments and trends in electrochemical sensing

Variation in oil content and fatty acid composition of linseed (Linum usitatissimum L.) cultivars and their hybrids in sub-mountainous Himalayan region of India

The study assessed the level of variation in oil content and fatty acid composition of linseed cultivars, elite lines and hybrids in sub-mountainous Himalayan region of India. The oil content ranged from 34.60 to 41.14 % in the experimental material. Yellow seeded cultivars had higher oil content in comparison to brown seeded genotypes. Two saturated (Palmitic and steric acid) and three unsaturated fatty acids (Oleic, linoleic and linolenic acid) identified by gas chromatography represented 8.81% and 90.89% of the total oil, respectively. Widest range of variation was observed for linolenic acid followed by oleic acid,while the highest GCV was recorded for linoleic acid. Cross combinations exhibited wider range of variation for linolenic acid in comparison to the parents. All the traits exhibited low heritability and low genetic advance except 1000-seed weight. Oil content showed weak positive association with seed weight. Palmitic acid also showed positive association with oleic acid however, linoleic acid had negative association with linoleic, oleic and stearic acid. Results indicated that induced mutagenesis coupled with recombination breeding will be more beneficial for the development of low linolenic acid lines in linseed
