Abstract. Maize is one of the top agricultural commodities that has great share in the Agricultural Government Development Plan of Nepal. Despite being a major crop, productivity of maize is quite lower than global average. In this context, a study was undertaken to determine the extent of technology adoption between improved and local seed users of Arghakhanchi district of Nepal. A pretested semi-structured questionnaire was administered among 120 randomly selected farmers during the month of January 2018. The extent of technology adoption was measured on sowing time, seed replacement, variety change, seed rate, application of fertilizer, weeding and plant protection. The empirical evidence suggested that, extent of technology adoption and benefit cost ratio were magnificently higher for improved seed users than local seed users. So, there is still a gigantic scope to improve maize productivity in the area by adoption of recommended technology of maize farming. The probability of adoption of recommended technology (improved seed) for maize farming was found to be higher for those with access to extensive service. Overall, our study pointed out that extension facility is a key strategy to make famers aware of the new technologies and a crucial factor to increase the chance of adoption.

Rani Lakshmi Bai Central Agricultural University, Jhansi conducted 40 front line demonstrations on mustard crop under the varieties - DRMR IJ-31, NRCHB -101, RH-749, NRCDR-2 and RH-406 during 2016–17. The critical reasons were identified in existing production technology through surveys and meetings with farmers. Sowing time, use of higher seed rate which resulted into high plant population, uneven plant population, more weeds, in balance dose of fertilizers and less use of plant protection measures were main causes of low productivity of oilseeds in district Jhansi. The results of study showed that the yield under demonstration plots was 12.82 q/ha as compared to 9.78 q /ha in traditional farmer practices plots. The results clearly indicate the positive effects of FLDs over the existing farmer’s practices. Benefit: cost ratio was also recorded higher under demonstrations against farmer practices during the year of experimentation.

Abstract Oil prices see large fluctuations peculiarly over the last eight years due to natural disasters, political instability, and Covid-19 pandemic shock. These prompt to anxiety towards expenditure in planning and forecasting of a field development plan (FDP). Economic optimization of a reservoir under water drive can be extremely tedious and time consuming especially for complex field. Traditionally, upon completion of forecast optimization on fluid production, reservoir engineer willhand over the reservoir models to petroleum economist for economical evaluation. If the chosen development strategy is not economically viable, the model strategies will have to be updated, and continue the repetition of financial evaluation all over again. Hence, this paper established an automated workflow that diminished the dilemma on iterations obligation between simulation runs and financial reviews in searching for most efficient waterflooding strategy. The automated workflow is accomplished by bridging three tools together seamlessly utilizing python scripting. These include the cash flow economic spreadsheet model, the dynamic simulator, and an assisted uncertainty analysis tool. The process first started with defining the economic parameters such as OPEX, CAPEX, oil price, taxes, discounted rates, and other financial parameters on an annual basis in spreadsheet. The uncertainty parameters: water injection rate, maximum water cut, and injection duration will be evaluated during forecast optimization to produce project efficiency indexes: Net Present Value (NPV) and Benefit-Cost Ratio (BCR). This integration was achieved by python script that automatically creates a coding path which exchanges simulation production and economic spreadsheet data at every simulation time step and each development strategy, that require no manual intervention. The integrated economic-dynamic model workflow has successfully applied on West Malaysian field and Olympus model, a development strategy that maximize oil recovery without neglecting cost of water disposal, storage for total water produced from the reservoir. This paper successfully identified the most efficient waterflooding strategy and production constraints for each well using BCR as objective function for optimization. The optimum development scenario does have a BCR which is more than 2 which show that investment on that particular development strategy is profitable. The results also demonstrated a crucial impression that the highest oil cumulative production may not results in high BCR due to cost involvement in resolving water production and field maintenance services. This paper outlined the methodology, python scripting codes, and how integration automation works that successfully optimized an injection strategy in a development project using economic model from third-party application. The results of this automated workflow demonstrate a successful utilization of new technologies and simple customize programming knowledge that promote cross-discipline integration for enhanced work-time efficiencies in problem solving that is suitable for all reservoir model type to determine its success rate and economic viability during FDP.

Background: Maize is one of the predominant millets cultivated in an area of 6500 ha both under drip and open irrigation systems in Dharmapuri district. The infestation of invasive insect pest Spodoptera frugiperda poses major threat to maize cultivation and increased the cost towards plant protection since 2018. In the integrated pest management strategies, the benefits of growing border and inter crop has been studied in detail but least emphasis was given to the crops grown in adjacent fields to the main crop. The cropping pattern in Dharmapuri district is highly diversified and the farmers prefer to grow more number of crops across the seasons compared to other maize growing areas. Methods: The present survey envisages the influence of adjacent and border crops on the incidence of fall armyworm in maize. The field incidence of fall armyworm in maize crop surrounded by other crops such as tapioca, nerium, cotton and maize fields with blackgram, cowpea and sesame as border crops were studied during kharif season of 2018 and 2019. Result: The maize fields surrounded by tapioca and nerium crop recorded lower fall armyworm incidence (3.00 - 10.00%) followed by field surrounded by tapioca on either side of maize (4.50 - 14.50%) during 15 to 60 days after emergence. Growing of border crops such as blackgram, sesame and cowpea recorded 24.50, 23.50 and 16.50% incidence at 60 DAE, respectively. With regard to grain yield, no marked variation was observed in different crop combination. The higher return (Rs. 86040/ha) and benefit cost ratio (2.65) was observed in maize crop adjacent to tapioca and nerium crop. The lower net return (Rs. 75360/ha) and benefit cost ratio (2.36) was realized in maize crop adjacent to maize crop. In most of the management strategies pulses have been inducted either border or intercrop to attract natural enemies and thwart the host insects. In the present survey, tapioca and nerium crop combination reduces the fall armyworm incidence. Hence tapioca and nerium crop combinations can be tried as border crop to push the fall armyworm away from the maize crop. The days required for advanced planting and crop combinations should be studied in detail to devise effective fall armyworm management strategies.

A field trial on soil test based (STB) fertilizer doses was conducted during the year of 2017-2018 and 2018-2019 in Jashore region (AEZ-11) to find out the most suitable fertilizer doses for four crop based cropping pattern considering the agronomic feasibility and economic return of the system. The experiment consisted of eight different treatments viz. T1: 100% NPKSZnB (STB), T2: T1 + 25% N, T3: T1 + 25% NP, T4: T1 + 25% NK, T5:T1 + 25% PK, T6:T1 + 25% NPK, T7: 75% of T1, T8: Native fertility. Randomized complete block design (RCBD) with three replications was followed. Data revealed that seed yield of mustard was remarkably influenced by fertilizer treatments while grain yield of other components of the cropping system was not affected significantly by the treatments except control or native fertility. It was observed that 25% more NPK over 100% STB dose provided the highest yield of all the component crops. The highest rice equivalent yield (3.34 t ha-1) was recorded from T6 and the lowest (1.88 t ha-1) from T8 treatment. Maximum gross return (Tk. 420000/ha) and marginal benefit cost ratio (4.08) were also obtained from T6 treatment. So, 25% NPK+ 100% STB dose of fertilizer could be followed for productive and remunerative rice based cropping system Mustard-Boro-T. Aus-T.Aman in AEZ-11. Bangladesh Agron. J. 2021, 24(1): 109-117

The study investigated the yield performance of transplant aman rice cv. BRRI dhan49 and boro rice cv. BRRI dhan29 under improved package of cultivation (TEGRA) as compared to farmers’ practice. TEGRA is a rice farming practice which includes use of quality seeds and healthy seedlings, transplanting with rice transplanter, use of herbicide, use of balanced fertilization and micronutrients, and preventive plant protection measures. The study during transplant aman season included two treatments on rice cultivation method viz. TEGRA package and farmers’ practice while in boro rice four treatments viz. TEGRA package, farmers’ practice with high inputs, farmers’ practice with medium inputs and farmers’ practice with low inputs. The yield and plant characters of both transplant aman and boro rice were significantly influenced by the TEGRA package of cultivation as compared to farmers’ practice. TEGRA package of cultivation as compared to farmers’ practice increased the grain yield by 18.3% in transplant aman rice and by 80% in boro rice with less cost of production as compared to farmers’ practice, which eventually resulted 23% increase in gross return and 400% in net return. As a result, the benefit cost ratio of TEGRA package was much higher (1.35 and 2.20 during transplant aman rice and boro rice, respectively) compared to that of farmers’ practice (1.07 and 1.30).Bangladesh Agron.

The study was carried out during rabi season of 2015-16, 2016-17 and 2017-18 in 6 villages across 3 blocks (Rajsamand, Railmagra and Amet) of Rajsamand district. In all 225 front line demonstrations on chickpea crop were carried out in an area of 90.0 ha with the active participation of farmers with the objective to demonstrate the latest technology of chickpea production potential, technological gap, extension gap, technology index and economic benefit of improved technologies consisting suitable varieties GNG 1581, integrated nutrient management (20:40:0 NPK kg/ha + Rhizobium + PSB @ 20 g/kg seed) and integrated pest management (deep ploughing + seed treatment with Trichoderma viridae @ 6 g/kg seed +pheromone trap @ 10/ha + spray of Quinalphos @ 1.2 l/ha with 600 litres of water) at Rajsamand, Railmagra and Amet blocks of Rajsamand district during 2015-16 to 2017-18. The results revealed that FLD recorded higher yield as compared to farmers’ practices over the years of study. The improved technologies recorded average yield of 18.94 q ha-1 which was 27.97 per cent higher than that obtained with farmer’s practices of 14.81 q ha-1. In spite of increase in yield of chickpea, technological gap, extension gap and technology index existed which was 4.06, 4.13 q ha-1 and 17.67 per cent, respectively. The extension gap can be bridged by popularizing package of practices where in stress need to be laid on improved variety, use of proper seed rate, balanced nutrient application and proper plant protection measures. Improved technologies gave higher net return of Rs. 67727 ha-1 with benefit cost ratio 4.88 as compared to local check (Rs. 50487 ha-1, benefit cost ratio 4.22).

Background: Study has been undertaken in SAT (Semi-arid tropics) region located between 23o 8'- 26o 30' latitude and 78o11'- 81o30' longitude with an altitude varying from 230 to 280 m above mean sea level (MSL), Central India for assessing the impact after interventions of natural resource management (NRM) under watershed development programme. Agricultural productivity of Semi-arid tropics oscillates between 0.5 and 2.0 ton ha-1 with an average of one ton per ha (Rockstrom et al., 2010; Wani et al., 2011a, 2011b). The main objectives of this study are to establish agroforestry based crop cultivation which provides nutritional food as well as transform the mankind’s living status and also supports the doubling farmer’s income goal without associated ecological harm. Methods: To evaluate the economic feasibility and crop productivity along with agroforestry was worked out on the basis of survey and sampling. To get uniform samples of crops from cultivated fields some specific area selected (1 m x 1 m size) and get about 80 crop samples for measurements from whole watershed. All data has been collected through survey of 40% households of watershed and then all these data subjected to statistical analysis in the laboratory. To minimize the problem and rejuvenate the water body, water resource development plan helps in identify the available sources so that appropriate and effective with durable solutions can be formulated. The net return of crop cultivated was calculated by subtracting the cost of cultivation incurred from sowing to harvesting, for each crop from the gross return and then benefit-cost ratio was estimated for further improvement or scaled up and livelihood security of former. Result: The study has revealed that after watershed interventions and agroforestry based Crop cultivation, water level increased 2-6 m, crop production increased by 45-47%, cropping intensity increased 97-98% from 44-46% and migration decreased by 70-72%. During both season, the expenses on irrigation and labour will decrease, crop productivity will improve and benefit-cost ratio increased. Nutrition based food production provided the base for food security as it is a key determination of food availability.
