“…Moreover, inoculating probiotics is a promising approach to ensure the dominant bacteria are beneficial organisms (Crab et al, 2012). While it is common to amend the growing environment for better plant nutrient uptake and a higher yield, there is little information about the optimal C/N ratio in nutrient solutions for plant cultivation (Rodríguez-Kábana, 1986;Schenck, 2001;White, 2012;Pyakurel et al, 2019;Li et al, 2020).…”

Integrated aquaponic food production systems are capable of producing more food on less land using less water than conventional food systems, and marine systems offer the potential of conserving freshwater resources. However, there have been few evaluations of species combinations or operational parameters in marine aquaponics. The goal of this experiment was evaluation of stocking density ratio of Pacific whiteleg shrimp (Litopenaeus vannamei) to three edible halophytes (Atriplex hortensis, Salsola komarovii, and Plantago coronopus) with two C/N ratios in a 3 × 2 factorial design. There were three stocking density ratios (shrimp: plant), 2:1, 3:1, and 5:1; and two C/N ratios, 12 and 15. The results indicated that stocking density ratio exerted a significant impact on shrimp growth. Shrimp reared in 2:1 and 3:1 treatments had better growth performance. In contrast, plants were affected by both stocking density ratio and C/N ratio. Halophytes grown in stocking density ratios of 3:1 and 5:1 with a C/N ratio of 15 had better growth performance and nutrient content. The concentrations of TAN and NO2– were below 0.2 mg/L throughout the experiment, including the higher stocking density ratio treatments. In conclusion, the stocking density ratio of 3:1 with a C/N ratio of 15 was suggested as the optimal condition for the operation of marine aquaponics in which whiteleg shrimp and the three halophytes are target crops.

“…Farmers of KMC apply higher dose of NPK than Marin but the dose was far below recommended practice. This is due to timely unavailability of chemical fertilizers (Dahal and Bhandari, 2019;Pyakurel et al, 2019). Recommended dose of NPK for maize cultivation in Nepal is 105 kg, 65kg and 50 kg/ha (MoAD, 2018).…”

The study was conducted to determine the resource use efficiency, profitability and demography of maize farming in Sindhuli district. This study was conducted in 120 maize producers, 60 from Kamalamai Municipality (KMC) and 60 from Marin rural municipality. Pretested semi-structured questionnaire was administered to randomly selected farmers. Maize producers were interviewed using face to face interview method in the month of October 2018. All the data were entered into SPSS and Microsoft excel and analysis was done by using Microsoft excel and SPSS. Cobb- Douglas production function was used to determine the resource use efficiency of maize production. Benefit cost ratio in the research area is 1.20 which indicates that maize production was profitable and farmers of Sindhuli get additional 20 paisa with investment of one rupee in maize farming. Productivity, cost and income per hectare of maize farming in Sindhuli was 1.98 tons, Rs 42423.3 and Rs 50805 respectively. 10% increase in chemical fertilizer, FYM and seed cost resulted in increase in income by 7.21%, 2.43% and 0.6% respectively. 10% increase in labor and animal power resulted into 0.2% and 0.07% decrease in output. For optimal allocation of resource expenditure on seed and chemical fertilizer were need to be increased by 89.93% each. Labor, animal power and FYM were over utilized resources for maize farming. The sum of coefficients was 0.983 which implied decreasing return to scale, 100% increase in all the factor of production included in the model would result in 98.30% increase in maize production.

“…Drip irrigation increase water use efficiency reducing unnecessary loss of water (Narayanamoorthy, 2004). Most of the Farmers of Dhading applied organic manure to acclimatize with declining soil fertility as it improves soil properties (Pyakurel et al, 2019). Crop residue retention improves soil fertility (Jangam and Rupa, 2017).…”

Climate change is one of the most challenging problems for the agricultural development. The purpose of this study is to analyze perception of climate change, its impacts and determinants among vegetable growers and to identify major adaptation strategies used by them. The study was based on survey of 75 vegetable growers; 34 from Benighat Rorang rural municipality and 41 from Siddhalek rural municipality of Dhading district of Nepal. Data were collected using face to face interview. The study provided empirical evidence of decreased in intensity, duration and frequency of rainfall and increase in annual temperature, drought duration and frost severity. Incidence of disease and pest, decline in soil fertility, scarcity of water and severe frost/hailstones were major problems. The 45.33% vegetable growers were compelled to change planting and 54.67% of them to change harvesting due to climate change effect. The adaptation practices such as mulching (24%), green/plastic house (29.3%), drip irrigation (8%), IPM (12.5%), change in crop variety (31.3%) and cropping pattern were found common practices adopted by farmers. The probability of adapting climate change mitigating factors was 70.26% higher for those who had received training in vegetable cultivation. Use of new climate smart agricultural technologies and providing training about vegetable cultivation were found suitable strategies to mitigate the negative impacts of climate change. SAARC J.
