Biomass assessment study in Koshi zone of Bihar was carried out at regional Research Station, Agwanpur, Saharsa during 2015-2016. Study was focused only on ACZ-II in first phase. For the study of different fate of residues of crops in Zone-II of Bihar, it was concentrated in the districts of Purnea, Katihar, Saharsa, Supaul, Madhepura, Khagaria, Araria and Kishanganj.  In first scenarios were feeding of livestock with dry biomass for 200 days in a year, it was observed that all the districts were deficient in providing biomass to live stock. However, in second scenario were feeding of livestock with dry biomass for 300 days in a year, all the district except Araria were deficit in providing biomass to livestock. There is no such problem arises for management of excess crop residue in these areas as these areas are already in deficit condition for biomass.

Canadian Context

In this study, the processes of wheat residue degradation in combination with various tillage treatments were explored to determine the ideal management prescription for maximizing canola crop production. A field experiment within a western Canadian context (near Saint-Front, Saskatchewan), consisting of a 2 × 3 factorial design, was conducted to determine the fate of crop residue under different harvest and treatment scenarios. ATR-Fourier transform infrared (FTIR) spectroscopy, FTIR spectromicroscopy, and synchrotron-based X-ray fluorescence imaging (SR-XFI) were used to explore wheat residue degradation mechanisms. The results indicated maximum canola yields and residue degradation occurred in combination with a combine outfitted with an aftermarket chopper and post-harvest treatment by harrow. Crop residue degradation was attributed to cellulose/linen hydrolysis and supramolecular structure changes from high crystalline to amorphous cellulose. Multi-element loss usually accompanied crop residue degradation. An important aspect of this study is the adoption of field-scale analysis to accurately portray real-world sustainable management techniques within a western Canadian context. The findings provided an optimal combination of crop residue treatment and tillage treatment to increase canola production, which had the potential ability to be applied in other countries. It is also an initial attempt to develop a technical composite of FTIR spectromicroscopy and SR-XFI for examining the mechanism of residue decomposition.

The Impact

Society is increasingly demanding a more sustainable management of agro-ecosystems in a context of climate change and an ever growing global population. The fate of crop residues is one of the important management aspects under debate, since it represents an unneglectable quantity of organic matter which can be kept in or removed from the agro-ecosystem. The topic of residue management is not new, but the need for global conclusion on the impact of crop residue management on the agro-ecosystem linked to local pedo-climatic conditions has become apparent with an increasing amount of studies showing a diversity of conclusions. This study specifically focusses on temperate climate and loamy soil using a seven-year data set. Between 2008 and 2016, we compared four contrasting residue management strategies differing in the amount of crop residues returned to the soil (incorporation vs. exportation of residues) and in the type of tillage (reduced tillage (10 cm depth) vs. conventional tillage (ploughing at 25 cm depth)) in a field experiment. We assessed the impact of the crop residue management on crop production (three crops—winter wheat, faba bean and maize—cultivated over six cropping seasons), soil organic carbon content, nitrate (${\mathrm{NO}}_{3}^{-}$), phosphorus (P) and potassium (K) soil content and uptake by the crops. The main differences came primarily from the tillage practice and less from the restitution or removal of residues. All years and crops combined, conventional tillage resulted in a yield advantage of 3.4% as compared to reduced tillage, which can be partly explained by a lower germination rate observed under reduced tillage, especially during drier years. On average, only small differences were observed for total organic carbon (TOC) content of the soil, but reduced tillage resulted in a very clear stratification of TOC and also of P and K content as compared to conventional tillage. We observed no effect of residue management on the ${\mathrm{NO}}_{3}^{-}$ content, since the effect of fertilization dominated the effect of residue management. To confirm the results and enhance early tendencies, we believe that the experiment should be followed up in the future to observe whether more consistent changes in the whole agro-ecosystem functioning are present on the long term when managing residues with contrasted strategies.

This study was undertaken on the topic, “Women role and status in Pukjtoon Society; A case study of village Sufaid Deri, Peshawar). For this study the researcher selected 70 respondents on purposive sampling basis from the fixed age group of 25-45 years of age.Interview schedule was used as the tool of data collection due to illiterate respondents. The study indicates that the women role and status is determined in puktoon society by the male. Her general role is only home management; Cleaning, Washing, Cooking, Budget Making, Agriculture Activities (Livestock & Poultry etc), Sewing and Embroidery making, Socialization of Children, Participation in Ceremonial activities and female oriented Job/ Service. Her contribution in decision making includes; Socialization & Education, Home Management, Health Care, Family Planning, Budget Making, Time table of Work and Game / Play, Salary / Income Keeping and Spending, Participation in Ceremonial Activities, Sharing / Suggestion in Every matter. Her economic role includes; Job / Service, Selling daily used commodities, Live Stock / Milk Products, Poultry Products and Netting, Sewing and Embroidery making and selling. Her social role consists upon; Participation in Marriage ceremonies, Participation in Death Ceremonies, Participation in traditional and all types of ceremonies. Problems faced by women in their productive role-play; Women are less advantaged, lack of mobility, Limited education, no access to resources, invisible partners of development, low health, low levels of nutrition, high rates of mortality, male dominancy and patriarchy. To improve the role and status of puktoon women it was recommended that women education should be improved and they should be given equal participation in developmental activities of the society. Key Words: Home management; Cleaning, Washing, Cooking, Budget Making, Agriculture Activities (Livestock & Poultry etc), Sewing and Embroidery making, Socialization of Children, Participation in Ceremonial activities and female oriented Job/ Service.

Carbon Dioxide Fluxes

Understanding the impacts of agricultural practices on carbon stocks and CO2 emission is imperative in order to recommend low emission strategies. The objective of this study was to investigate the effects of tillage, crop rotation, and residue management on soil CO2 fluxes, carbon stock, soil temperature, and moisture in the semi-arid conditions in the Eastern Cape of South Africa. The field trial was laid out as a split-split-plot design replicated three times. The main plots were tillage viz conventional tillage (CT) and no-till (NT). The sub-plots were allocated to crop rotations viz maize–fallow–maize (MFM), maize–oat–maize (MOM), and maize–vetch–maize (MVM). Crop residue management was in the sub-sub plots, viz retention (R+), removal (R−), and biochar (B). There were no significant interactions (p > 0.05) with respect to the cumulative CO2 fluxes, soil moisture, and soil temperature. Crop residue retention significantly increased the soil moisture content relative to residue removal, but was not different to biochar application. Soil tilling increased the CO2 fluxes by approximately 26.3% relative to the NT. The carbon dioxide fluxes were significantly lower in R− (2.04 µmoL m−2 s−1) relative to the R+ (2.32 µmoL m−2 s−1) and B treatments (2.36 µmoL m−2 s−1). The carbon dioxide fluxes were higher in the summer (October–February) months compared to the winter period (May–July), irrespective of treatment factors. No tillage had a significantly higher carbon stock at the 0-5 cm depth relative to CT. Amending the soils with biochar resulted in significantly lower total carbon stock relative to both R+ and R−. The results of the study show that NT can potentially reduce CO2 fluxes. In the short term, amending soils with biochar did not reduce the CO2 fluxes compared to R+, however the soil moisture increases were comparable.

Crop Residue Management

Crop residue management (CRM) through conservation agriculture can improve soil productivity and crop production by preserving soil organic matter (SOM) levels. Two major benefits of surface-residue management are improved organic matter (OM) near the soil surface and boosted nutrient cycling and preservation. Larger microbial biomass and activity near the soil surface act as a pool for nutrients desirable in crop production and enhance structural stability for increased infiltration. In addition to the altered nutrient distribution within the soil profile, changes also occur in the chemical and physical properties of the soil. Improved soil C sequestration through enhanced CRM is a cost-effective option for reducing agriculture's impact on the environment. Ideally, CRM practices should be selected to optimize crop yields with negligible adverse effects on the environment. Crop residues of common agricultural crops are chief resources, not only as sources of nutrients for subsequent crops but also for amended soil, water and air quality. Maintaining and managing crop residues in agriculture can be economically beneficial to many producers and more importantly to society. Improved residue management and reduced tillage practices should be encouraged because of their beneficial role in reducing soil degradation and increasing soil productivity. Thus, farmers have a responsibility in making management decisions that will enable them to optimize crop yields and minimize environmental impacts. Multi-disciplinary and integrated efforts by a wide variety of scientists are required to design the best site-specific systems for CRM practices to enhance agricultural productivity and sustainability while minimizing environmental impacts.
