A field experiment was conducted with the purpose of testing and evaluating the use of a closed-loop, real-time control system which was developed by (Elnemr M.K., 2017) for application to a poor hydraulic performance drip irrigation system with sandy loam soil cultivated with cucumber crop. This control system collects soil moisture data through three sensors distributed along each third of the lateral. The control system was based on calculating the average soil moisture content (MC) of the three readings and using it as an indicator to start or stop irrigation process according to the requirements of the plant. The control system will start the pump after the depletion of allowed MC percentage of available water which is one of the required inputs to operate the control system. The irrigation process continues until reaching the field capacity (FC) value. The study compared two management methods for the irrigation system. First one was using the proposed control system (Aum) and the other one was manual operation based on calculating water requirement from climatic data (Clm). Using the proposed control system led to increase cucumber crop production by 23.8% of Clm productivity. The control system led to save water and seasonal irrigation time. This led to increase water productivity and energy use efficiency of Aum if compared to Clm by 41.71% and 110% respectively. Despite the added cost to the irrigation system because of the control system, the benefit/cost ratio for Aum was higher by 24.39% due to the decrease in energy and labour costs in addition to the increase in crop production. The study recommended using the researched control system with drip irrigation systems which show poor hydraulic performance to reduce negative effects on crop production and to reach more efficient use for both water and energy with keeping the opportunity to increase benefit/cost ratio. Further studies should be done on the system with drip irrigation system that work under acceptable ranges of hydraulic performance. Also, further studies should be done to investigate the most effective and suitable distribution of the sensors along lateral.

The study was conducted in Chandel district of Manipur state to maximise the productivity of Rapeseed-mustard under rice fallow. Rapeseed-mustard has great potential under residual moisture after the harvest of Kharif rice in North Eastern states. It is a major source of income especially to the marginal and small farmers in rainfed areas of Manipur. Sample consisted of randomly selected 29 farmers who were growing rapeseed-mustard under FLDs. The results revealed that improved technology recorded a mean yield of 8.77 q/ha which was 20.55 per cent higher than obtained under farmers’ practice (7.27 q/ha). The study also showed that reduction in technology index from 10.90 per cent during 2017-18 to 6.49 per cent during 2019-20 exhibited the feasibility of demonstrated technology. The lower value of technology index, the more is the feasibility of technology. Further, it was found that the adoption of improved technologies not only increased the yield but also yield attributing traits of rapeseed-mustard and benefit cost ratio. Hence, there is a need to disseminate the improved technologies amongst the farmers with effective extension methods like training and demonstrations to utilise the rice fallow areas for increasing the cropping intensity as well as to increase crop production and productivity. The farmers’ should be encouraged to adopt the recommended package of practices for realizing higher returns.

Background: Potato (Solanum tuberosum) popularly known as ‘The King of Vegetables’, has emerged as fourth most important food crop in the world after rice, wheat and maize. Indian vegetables basket is incomplete without potato as its, dry matter, edible energy and edible protein makes it nutritionally superior as well as staple food throughout the world. Methods: The experiment during 2016-2018 was laid out in factorial randomized complete block design with three replications to study the effect of bed size on the yield and size of the tuber under different irrigation methods. Results: Maximum yield was obtained in 60cm bed (narrow bed size) whereas in irrigation system drip produced maximum yield. All quality parameters did not influence due to sowing method and irrigation system but chip recovery was more in drip irrigation than furrow system. Maximum yield through interaction was found in drip irrigated 105 cm triple row bed. Around 45-50 per cent water was saved through drip irrigation as compared to furrow irrigation. However, maximum benefit cost ratio was obtained in furrow irrigated 60cm bed size.

Maize cultivation is the one the major farm activities among Nepalese farmers. Basically, in the rural hills of Nepal like Okhaldhunga, it dominates any other crop production. The study was conducted for comparative assessment of economics, marketing and identification of major problems of maize seed and grain production in the hilly eastern district, Okhaldhunga during June of 2017. The data were obtained through the interview of 66 producers (33 each of maize grain and seed producers) with a pre-tested semi-structured questionnaire. Descriptive statistics and parametric tests (-test, t-test) were applied. Both the grain and the seed producers were similar in terms of socio-demographic characteristics, marketing accessibilities but the seed producers were significantly benefited from the training, the extension services, credit facilities despite having 0.14 ha lesser landholding than grain producers. The inputs (manures, fertilizers and the seed) contributed 48% and 50% of the total cost incurred for grain and seed production respectively and the pre-sowing and sowing activities contributed more than 77% of cost in both cases. Despite higher cost for seed production (NRs. 24,969 more than grain production), the benefit-cost ratio of seed production was found higher (1.31) than grain production (1.05). Only 24% of the total harvest was processed and marketed as seed and using optimum quantity (66% middle portion of the cob) for seed production could further increase the income by 23.35%, the improved B:C ratio being 1.51 . The major production problems were scarce farm labor followed by lack of infrastructures while low seasonal price followed by low volume of production ranked the first and second most important marketing related problems.
