    Abstract IntroductionDeveloping an intensive sustainable model and feeding a rising population are worldwide challenges. The task is much more daunting in the North Eastern Himalayas, where, low productive maize (Zea mays)maize (Zea mays) fallow is the main production system in the upland. To increase farm productivity, nutritional security, and energy dietary returns while maintaining environmental sustainability and economic viability, short-duration crops must be included in the maize–fallow system.MethodsA field study was conducted in sandy clay loam soil with a randomized complete block design with three replications for three continuous years (2018–2021) under organic management with two crop management practices, viz., (i) conservation agriculture and (ii) conventional agriculture, and six crop diversification options, viz., (i) maize–sweet corn (Zea mays saccharata)–vegetable pea (Pisum sativa) (M-SC-VP), (ii) maize–sweet corn-mustard (Brassica juncea) (M-SC-M), (iii) maize–sweet corn–lentil (Lens culinaris) (M-SC-L), (iv) maize–sweet corn–vegetable broad bean (Vicia faba) (M-SC-VB), (v) maize (local)–vegetable pea (M-VP), and (vi) maize (local)–fallow (M-F).ResultsThe results showed that, the average system productivity was 5.3% lower for conventional agriculture than conservation agriculture. System carbohydrate, protein, fat, dietary fiber, and dietary energy were ~6.9, 6.8, 7.8, 6.7, and 7%, higher in conservation agriculture than in conventional agriculture, respectively. Similarly, system macronutrients (Ca, Mg, P, and K) and system micronutrients yield (Fe, Mn, Zn, and Cu) were, 5.2–8% and 6.9–7.4% higher in conservation agriculture than in conventional agriculture, respectively. On average, over the years, crop diversification with M-SC-VP/M-SC-VB intensive crop rotation had higher system productivity (158%), production efficiency (157%), net returns (benefit–cost ratio) (44%), and dietary net energy returns (16.6%) than the local maize–vegetable pea system. Similarly, the M-SC-VP/M-SC-VB system improved ...

    Abstract ABSTRACTClimate change and its impacts on agriculture are relatively well documented at the global and regional levels, while adaptation measures to sustain food production are mostly location specific. Such measures integrated into a production system as a farming practice will become robust based on its performance at smallholder farms. Therefore, a long-term (2011-2018) study was undertaken to evaluate these practices in a crop-livestock integrated farming system (IFS) approach as a climate-smart agricultural (CSA) strategy for enhancing agricultural production on a humid tropical island. The results showed a significant increase in on-farm productivity from 2.8 t ha−1 in 2011–35.6 t ha−1 in 2018 and net returns from USD 359 to more than 3500 ha−1 due to the adoption of CSA practices. Most importantly the study found increase in the sustainability index (0.89) by the adoption of CSA practices such as crop and enterprise diversification and land manipulation. The climate smartness of these practices was witnessed in reduced greenhouse gas (GHG) emissions and expanded carbon sink that resulted in a mitigation benefit of 5.40 Mg CO2eq ha−1yr−1. CSA practices such as crop diversification through raised beds, enterprise diversification, crop rotation, green manuring, in-situ rainwater harvesting, and contingency cropping significantly contributed to enhancing the production of crop-livestock IFS. Crop residue mulching, agro-forestry and organic waste recycling contributed for enlarging the C sink and minimizing net GHG emissions. Based on these findings, we demonstrated that a crop-livestock IFS was the best climate-smart strategy to enhance the productivity and food security of smallholder farmers in a sustainable way against the consequences of climate change and to increase the mitigating potential through carbon stocking.

    Abstract A field experiment was conducted to evaluate agrometeorological parameters associated with seed yield of Indian mustard (Brassica juncea L.) varieties in an organic production system. During the study, significant variation was recorded in crop phenophases, growth, yield attributes, and seed yield of mustard. Varieties NRCHB-101 and Pusa Mustard-25 have taken significantly minimum days to commence flowering (46–48 days) and attaining physiological maturity (89–90 days). Variety RGN-48 being at par with RH-406 and RGN-229, recorded significantly higher plant height, while RGN-229 recorded the significantly highest biomass accumulation at all the growth stages. Varieties RH-406, Pusa Bold, and DRMRIJ-31 recorded significantly higher seeds per siliqua (16.2–16.5), whereas significantly higher test weight was recorded in Pusa Bold (6.3 g) and DRMRIJ-31 (6.0 g). In seed yield, variety RH-406 (1.97 t/ha) and DRMRIJ-31 (1.42 t/ha) were found significantly highest and lowest, respectively. A significant positive correlations of mustard seed yield was noticed with biomass accumulation at 30 DAS (r=441**), 60 DAS (r=0.614**), 90 DAS (r=0.620**) and biological yield at harvest (r=0.496**). Contrary to test weight, seeds per siliqua had shown a positive effect (r=0.266*) on the seed yield of the mustard. Seed yield of mustard was also influenced by some agrometeorological indices with correlation coefficients (r) of mean minimum temperature at flowering and physiological maturity and mean maximum temperature at physiological maturity were -0.207*, -0.249*, and -0.241*, respectively. Net solar radiation and cumulative temperature difference at physiological maturity also had significant and positive effects on the seed yield of mustard.

    Abstract Abstract Adoption of an integrated farming system (IFS) is essential to achieve food and nutritional security in small and marginal holdings. Assessment of IFS to know the resource availability and socio-economic condition of the farm household, farm typology plays a critical role. In this regard, a sample survey of 200 marginal households practicing mixed crop-livestock agriculture was conducted during 2018–2019 at Southern Coastal Plains, which occupies 19,344 ha in Thiruvananthapuram district, Kerala, India. Farming system typology using multivariate statistical techniques of principal component analysis and cluster analysis characterized the diverse farm households coexisting within distinct homogenous farm types. Farming system typology identified four distinct farm types viz. resource constrained type-1 households with small land owned, high abundance of poultry, very low on-farm income, constituted 46.5%; resource endowed type-2 households oriented around fruit and vegetable, plantation crop, with a moderate abundance of large ruminant and poultry, high on-farm income, constituted 12.5%; resource endowed type-3 household oriented around food grain, extensive use of farm machinery, with a moderate abundance of large ruminant, low on-farm income, constituted 21.5%; and resource endowed type-4 household oriented around fodder, with high abundance of large ruminant, medium on-farm income, constituted 19.5% of sampled households. Constraint analysis using constraint severity index assessed the severity of constraints in food grain, horticulture, livestock, complementary and supplementary enterprises in each farm type, which allowed targeted farming systems interventions to be envisaged to overcome soil health problems, crops and animal production constraints. Farming system typology together with constraint analysis are therefore suggested as a practical framework capable of identifying type-specific farm households for targeted farming systems interventions.

    Abstract An inter-organizational certificate course i.e. Certified Farm Advisor (CFA) in Organic Farming was jointly organized by National Institute of Agricultural Extension Management (MANAGE), Hyderabad and ICAR-Indian Institute of Farming Systems Research, Modipuram, Meerut during 2019. The objective of this certificate course was to create a cadre of “Certified Farm Advisors†in appropriate technologies of organic farming and enable them to deliver effective “Technical Advisory Services†and thereby solving the field level problems faced by the organic farmers/entrepreneurs/startups or other related stakeholders. A 15 days CFA module II was organized at ICAR- Indian Institute of Farming Systems Research, Modipuram, Meerut in two batches with 50 trainees from 15 different states and union territories. In the present study, the learning, knowledge and skill levels of the participants were analyzed. Multiple regression analysis showed that, gender, service experience and serving region significantly affected the learning ability of trainees. There was significant improvement in the knowledge and skill of trainees in various aspects of organic farming, viz. organic standards, certification and marketing network (study area A); technology package (study area B) and general knowledge (study area C). Based on the training effectiveness scores (TES), maximum improvement was observed with general knowledge of organic farming with 103.73% improvement. However, study area A and B exhibited 45.41% and 34.88% improvement, respectively. Further, the success of this inter-organizational training programme could serve as a model for streamlining HRD programmes on organic farming in the country.

    Abstract In Indo-Gangetic Plains (IGP, ~18 mha geographical area), wheat (Triticum aestivum L.) is a predominant crop grown in rabi. Improving the productivity of wheat in a rice-based farming system through a suitable cultivar in IGP is necessary to evaluate under the agro-ecological condition of IGP of India. A farmer’s participatory field experiment was studied at three villages Saunta, Sathedi and Bhangela situated in Khatauli block of Muzaffarnagar (Uttar Pradesh) under two crop environments (low rainfall and high temperature, LRHT and heavy rainfall and low temperature, HRLT) with four wheat varieties during rabi of 2017–18 and 2018–19. In this study we have evaluated the productivity in isolation as well as in combination of prevailing weather scenario (2017–18 and 2018–19) under irrigated agro-ecosystems of Western Plain Zone of Uttar Pradesh. Interaction studied between crop environments and varieties indicated that PBW-550 and PBW 658 registered higher grain yield of 5514 and 5475 kg/ha, respectively than farmers practice (PBW-226, 4659 kg/ha) and DBW-90 (4647 kg/ha) in LRHT. However, under HRLT, PBW-658 performed better (5326 kg/ha) over other cultivars. Mean grain yield of all four cultivars were recorded significantly higher under LRHT with 5074 kg/ha compared to HRLT where mean grain yield was 4710 kg/ha. A highly significant (P=0.01) negative association was found between grain yield and monthly rainfall (except December month) and cumulative rainfall of the crop season (-0.322**). Prevailing mean monthly air temperature during grain filling to maturity phenophase was found to be positively associated with grain yield (r = -0.322*).

    Abstract In this study, the effects of integrated farming system on residue recycling and soil quality in rice-based integrated farming systems have been examined. The effective nutrient budget for nitrogen was found higher with rice-fishpoultry- cowpea and the negative values were obtained for rice-chili and rice-baby corn systems. However, the effective budgets for phosphorus and potassium were negative in all these cropping systems. The results indicated that, about ten tonnes of organic matter was recycled, and the major share was from the dairy unit (~52%) in the form of dung and cow urine. Total internal nutrient supply due to recycling was estimated at 55 kg of nitrogen, 17 kg phosphorus and 76 kg of potassium, which is equivalent to 118 kg urea, 106 kg single super phosphate and 126 kg muriate of potash, thus reduction in cost of inputs. In the rice+fish+poultry-cowpea system, the indices of soil quality showed higher values, which indicated the improvement in soil fertility due to availability of poultry manure, plankton production, and the continuous fish activity. The current study confirmed that available N, DHA, Zn, B and Fe as the key indicators of soil quality under humid tropics of west coast India, which greatly influence the soil functions and soil productivity. The study conclusively reveals that integration of dairy, fishery, poultry components with diversified cropping systems in coastal lowland ecosystem is essential to improve the nutrient use efficiency and for enrichment of soil fertility.

    Abstract The 26, December 2004 tsunami had major impact on the quality of groundwater along the south- east coast of India, but especially in the tsunami-affected areas of the Nagapatinam district of Tamilnadu. Major pollution resulted primarily from increases in the salinity of groundwater. The post- tsunami water quality posed problems to general health and contributed significantly to agricultural and environmental degradation in the Sirkazhi taluk and Nagapattinam districts. The adverse impact was particularly significant in the areas of Pazaiyar, Madavaimedu, Thirumullaivasal, Thoduvai, Koozaiyar, Puthupattinam, Kizhamoovarkarai, Poombhukar and Vanagiri. The present study assesses the source, degree, extent and nature of groundwater contamination in the Sirkazhi coastal region. Samples of groundwater were collected from 11 wells in this area and analyzed chemically to determine the extent of contamination. The results showed significant variations in water quality parameters in the study area and helped understand the longer-term adverse impacts that tsunami inundation can have upon groundwater resources.

    Abstract The first ever recorded historical evidence for surgical drains were found in the era of Hippocrates (circa 460-377 BC). The Greek Physician Hippocrates used hollow tubes for the treatment of empyema. Surgeries of the head and neck region are associated with clinically significant post-operative morbidities such as haematomas, seromas, surgical site infection and skin flap complications. “Closed surgical drains” are used widely to prevent such complications and is considered the standard of care for head and neck surgical wounds as they obliterate the dead space and prevent seroma and hematoma formation. The negative pressure created by a closed surgical drain improves the skin apposition and wound healing, particularly when extensive undermining had been done during dissection. “Radivac drains” (negative suction drains) are considered the standard of practice in head and neck surgery. However, the limited affordability of the healthcare systems in developing countries, drive clinicians to find cheaper alternatives to Radivac drains. This article elaborates the use of closed suction drain system assembled with 20cc syringe and Ryle’s tube which has been effectively used in the University Dental Hospital Peradeniya for decades.
