Assam is one of the major niger producing sates of India. Wide spread rice fallow and retreating northeast monsoon are the advantages for cultivation of rabi niger crop in Assam. However, niger yield under rainfed situation of Assam decreases drastically for every 15 days delay in sowing of the crop from 15th November to 30th December. The highest seed (4.1 q/ha) and stover (31.0 q/ha) yield could be obtained from 15th November sown crop. Nevertheless, sali rice is harvested late in Assam and so, delay sowing of next rabi crop leads to lower productivity of the crop. Application of 50% recommended dose of fertilizers (RDF) along with 50% nitrogen through FYM considerably increases yield attributing parameters that in the end maximize the stover and seed yield of niger crop. This can give 19.3 and 4.3% increase in stover and seed yield of niger respectively, over RDF. Thus, half of chemical fertilizers required for niger crop could be substituted through organic nutrient sources, which has also lead to an improvement in soil physico-chemical properties and higher availability of nutrients in soil. This review reported the detail management strategies for successful cultivation of rabi niger crop under rainfed situation of Assam of North-East region of India.

In 2013, a pilot experimental field of about 15 ha was set up within the basin of Lake Massaciuccoli (Tuscany, Italy) in order to compare different management strategies—a paludicultural system (PCS), a constructed wetland system (CWS), a nearly-natural wetland system (NWS)—for peatland restoration after almost a century of drainage-based agricultural use (CS). After five years, changes in peat soil quality were investigated from a chemical, biochemical, and ecoenzymatic perspective. The soil in CS was mainly characterized by oxidant conditions, higher content of overall microbial activity, low levels of easily available phosphorus for vegetation, and medium total carbon content ranging from 25.0% to 30.7%. In PCS, the levels of total carbon and the content of bioavailable P were higher, while the oxidant conditions were lower compared to the other systems. As expected, the soils in CWS and NWS were characterized by the most reduced conditions and by the highest levels of arylsulphatase activity. It was noteworthy that soils in the NWS systems were characterized by the highest level of nonavailable P. Outputs from ecoenzymatic activity confirmed the physico-chemical and biochemical results.

Now a days fried foods are very common everywhere around the world and it can be observed by the increasing number of fast food restaurants in the last few decades. Deep frying of foods at high temperature enhances the sensorial properties which include the unique fried flavor, golden brown colour and crispy texture. At the same time, so many chemical reactions like oxidation, polymerization, hydrolysis, etc., take place in the food system, which ultimately alters the physical and chemical properties of fat. Mustard oil is a vegetable oil which is widely being used in India for cooking purpose. The parameters like free fatty acid (FFA), peroxide value (PV), p-anisidine value (p-AV), total oxidation (TOTOX value), iodine value (IV) and colour are studied in this experiment. The heating oil parameter has been taken in such a way, considering the frying practices done in the restaurants of North-East India. The oil sample was taken after every 5 hours of heating mustard oil in deep fat fryer. The 30 hours of heating (5h/day) degrades mustard oil to such an extent that it becomes unadvisable for human consumption. The study showed that there is ample change in the chemical composition and the hunter colour showed that the oil has lost its luster and has become dark red.

The aim of this study was to investigate the effect of zinc enriched Farm Yard Manures (FYM) on zinc deficient loamy sand soil and yield of mungbean[Vigna radiata (L.) Wilczek.]. Treatments consisted of 15 combinations of three levels of FYM i.e. F0 (no FYM), F1 (FYM @ 5 t ha-1) and F2 (FYM @ 10 t ha-1) and five treatments of enrichment i.e. Zn enrichment (EnZn1, EnZn2, and EnZn3) at three levels of Zn (2.5, 5.0 and 7.5 kg Zn ha-1) @ 500 kg ha-1 FYM and without enrichment (Zn0 and Zn1) at two levels of Zn (inorganic salts) i.e. 0 kg and 5 kg Zn ha-1, replicated thrice in factorial randomized block design (FRBD)during 2012. The enrichment process was started 50 days before their use in kharif season experiment on mung bean.The average improvement in seed yield of mungbean was 1179 kg ha-1. Zinc-enriched FYM and their straight application produced (10983kgha-1) 31.86 and 22.83% higher grain yield, respectively, relative to control Zn0 (8959kg ha-1).The yield was increased due to enrichment and it was achieved by 9.04 % over straight application of zinc. Zn uptake was recorded significantly higher under the EnZn2 (143.96 g ha-1) which was at par with EnZn3 (148.23 g ha-1) followed by EnZn1 (118.50 g ha-1) all these values are significantly higher than Zn0 (92.02 g ha-1).The average improvement in total uptake of Zn by mungbean was 48.71%higher due to zinc enriched FYM than the straight application of zinc. The application of zinc enriched FYM significantly increased available N, organic carbon andDTPA-extractable Zn with increasing the level of enrichment.The application of zinc enriched FYM had non-significant effect on bulk density, saturated hydraulic conductivity and moisture retention at 1/3 and 15 bar and CEC than control.Application of 2.5 kg Zn ha-1which wascomparable to enriched with FYM,in terms of higher seed yield of mungbean.

Ethnic communities of North-East India consume various traditional beverages which are mostly prepared by fermentation of rice of their own. Many ethnic communities reside in Assam, India and the consumption of fermented drinks is always considered to be their culture and existence of the ethnic tribes. In present work, eight different rice beer samples are collected from different parts of Assam representing Ahom, Mising and Karbi community. The samples are characterized with respect to various physico-chemical analysis and microbiological parameters. In present work, the methodologies for the process of preparation of rice beers by different ethnic communities are also carefully observed and properly documented. It has been observed that all the samples are acidic in nature and the pH values are ranged from 2.83-5.05, while conductance ranged from 0.028-1.86 ms/cm. The amount of free carbon dioxide varies from 0.105 g/L to 6.81g/L. The amount of hardness varied from 0.012 g/L to 0.38 g/L. The sugar content of various rice beers ranged from below detection limit (BDL) to 4.4 g/100 mL while the percentage of ethanol varies from 2.2 to 5.7 g/100 mL. The correlation matrix study also shows a good positive correlation between conductance and TDS, hardness, free CO2 and bicarbonate alkalinity. In this study, no coliform bacterial contamination appeared while the colony forming unit ranged from 0.3 × 105 to 1.68 × 105 cfu mL-1.

In the present day context, the knowledge of the soil, water and its movement in the soil has key importance for optimum plant growth as well as having practical inferences in agricultural, hydrological and ecological situations. Hydraulic properties of soils play a significant role in the adoption of water management strategies capable of improving resource use efficiency and alleviating production constraints of soils worldwide. Hydraulic conductivity is the most important hydraulic parameter to regulate the flow and transport related phenomena in soil. Hence, there is a need for accurate and adequate information regarding the hydraulic properties in relation to soil physico-chemical properties. The aim of this paper is to extend the relationship between the hydraulic properties and other soil physico-chemical properties of soils. Many studies around the world reveal the effect of texture, soil organic carbon content, bulk density, pH, electrical conductivity, sodium adsorption ratio, aggregate stability index and soil water holding capacity on hydraulic properties of soils.
