The present experiment on Performance evaluation of drip irrigation system and profitability analysis of leafy vegetables under polyhouse was conducted to study the performance parameters of the drip irrigation systems relating to crop performance. This was done by taking existing drip tapeline, new drip tape line and new inline drip irrigation system under the Polyhouse at the college of Agricultural Engineering, Kandi, Sangareddy, Telangana during the year 2018. Profitability of five green leafy vegetables viz. Palak, Sorrel, Methi, Amaranths and Coriander was also evaluated. The results reveal that the three drip line systems in-line got more uniform coefficient of 98% followed by new drip tape with 96% and preinstalled drip tape with 95%. Among the five green leafy vegetables methi has recorded highest gross (306000Rs acre-1) and net returns (285833) and benefit cost ratio (14.2) followed by Palak, Sorrel whereas Amaranthus has recorded lowest benefit cost ratio (7.6).  In terms of performance characteristics, drip tape and in line system performed better in maintaining uniformity discharge and the designed drip irrigation operated excellently.  Methi, Palak ad sorrel found suitable and profitable in polyhouse where year- round cultivation of vegetables is feasible compared to open field in which crop establishment was very poor and could not be raised successfully due the heavy rains and growth characters of the leafy crops.

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.

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.

In this paper, fuzzy financial evaluation models are derived to analysis investment financial profitability and possibility for wind power generation project in Penghu, Taiwan. The financial subsidy and feed-in tariff (FIT) are two effective market mechanisms to promote wind power development in Taiwan. The performances of the proposed fuzzy profit models are verified by considering their application to a simulation case. The study shows the fuzzy financial indexes of the simulated 2,400 kW wind power project may little uneconomic possibility, with negative net present value, with benefit cost ratio smaller than 1, and with payback years longer than its life span, in both two scenarios. The FIT rates should be revised to match wind power current market to give more attractiveness for potential investors. The studied results are also consistent with those provided by the conventional crisp models, and provide readily implemented possibility analysis tools for use in the arena of uncertain finance.

Modern agriculture requires a modern approach which responds to the necessity of mankind. The study presents the fabrication and performance evaluation of a cassava grater with  juice extractor. Such performance evaluation was conducted to determine its grating and juice extracting capacity and efficiency. It was made from locally available materials then tested experimentally using cassava with a grating capacity of 160 kg/hr. The study employed the Complete Randomized Experimental Design (CRD). In evaluating the experiment, the Two-way Analysis of Variance (ANOVA) was used to determine the significant effect of each factor and the Tukey’s test was used to determine the significant difference between the combined treatments. Two factors with different levels were treated upon the experiment.  These were mainly soaking time (0 min, 5 min, 10 min, 15 min) and the way the cassava was grated and juice extracted (Machine, Manual).  Among these treatment combinations, the soaking time of 15 minutes obtained the highest grating and extracting capacity as well as for the grating and extracting efficiency leaving its quality and acceptable appearance on top.  The computed benefit-cost ratio of 1.86 showed that grating and extracting cassava juice using the cassava grater with juice extractor was highly profitable and economical for local cassava producers.

Abstract Drip method of irrigation (DMI) has the potential to save substantial water and electrical energy as well as increase the productivity of crops. Studies conducted on different high value crops have confirmed the various benefits of DMI. However, not many studies have researched the income and resource impact of drip irrigation including its benefit–cost pattern using survey data in crops like groundnut, which is an important oilseed crop in India. In this paper, an attempt has been made to fill this gap by using survey data collected from a water-scarce district from Tamil Nadu State in India. The results show that DMI can save about 34% of cultivation cost, 36% of water and electrical energy and increase about 79% of productivity over the same crop cultivated under conventional flood method of irrigation. The drip adopters are also able to generate an additional farm business income of Rs 25,911/acre (1 USD = INR 74.92, 1 acre = 4,047 m2) over the non-drip adopters. The net present worth and benefit–cost ratio estimated using discounted cash flow technique shows that investment in drip irrigation is economically highly viable for groundnut cultivating farmers.

The present study is an attempt to examine the socioeconomic characteristics and compared profitability analysis of both IPM and Non-IPM vegetable growers, and to identify the problems faced by vegetables growers in use of IPM practices in some selected areas of Kishoreganj district. A total of 45 farmers were purposively selected where three different IPM practices were taken into consideration. To get a more complete picture of vegetable production using both IPM and non-IPM technology, the socio-economic profile of farmers was examined and compared. The study found that IPM farmers were in better-off condition than that of non-IPM farmers in all types of socioeconomic characteristics. The major findings of the study revealed that production of all the selected vegetables were profitable for both IPM and non-IPM farmers. But, IPM based cultivation was more profitable than that of non-IPM based cultivation. Average total costs were Tk. 86352.8 and Tk. 100061.5 for IPM and non-IPM farmers, respectively. Average gross returns were Tk. 257293.3 and Tk.235788.8 for IPM and non-IPM farmers, respectively. The average net return for IPM farmers was Tk.170940.5 and for non-IPM farmers it was estimated at Tk. 135727.3. The average benefit cost ratio for IPM farmers was 2.9 and for non-IPM farmers it was estimated at 2.3. Most of the farmers were in the categories of low to medium problem confrontation in using IPM practices. The first ranked constraint is lack of training facility. Thus, massive extension facility including training is needed in the study areas to increase the extent of use of IPM technology.Progressive Agriculture 27 (3): 311-319, 2016

A field experiment on intercropping of okra and leafy vegetables was conducted at Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur and Agricultural Research Station, Burirhat, Rangpur during Kharif-I season of 2010 and 2011 to find out suitable crop combination for higher productivity and economic return. Seven treatments viz., sole okra (50 cm × 40cm), okra 100% (in row) + red-amaranth 100% (broadcast), okra 100% (in row) + red-amaranth 75% (broadcast), okra 100% (in row) + leaf amaranth 100% (broadcast), okra 100% (in row) + leaf amaranth 75% (broadcast), okra 100% (in row) + jute as patshak 100% (broadcast), okra 100% (in row) + jute as patshak 75% (broadcast) were used. Intercropping reduced okra yield but total productivity increased due to additional yield of vegetables. In both the locations, sole okra produced the highest yields (15.82 t/ha at Joydebpur and 13.79 t/ha at Burirhat). Among the intercropping treatments, the highest okra yields (15.42 t/ha at Joydebpur and 12.64 t/ha at Burirhat) were obtained from okra 100%+ red amaranth 75% combination. The lowest okra yield (13.16 t/ha at Joydebpur and 11.75 t/ha at Burirhat) was recorded in okra 100% + jute as patshak 100% combination. The highest okra equivalent yield (23.00 t/ha) was recorded in okra 100% + red amaranth 100% at Joydebpur and in okra 100% + leaf amaranth 100% (21.79 t/ha) at Burirhat. These treatment combinations also gave the highest gross margin (Tk. 227180/ha at Joydebpur and Tk. 214600/ha at Burirhat) and benefit cost ratio (5.66 at Joydebpur and 5.58 at Burirhat). The results revealed that cent percent red amaranth (broadcast) or leaf amaranth intercropped with cent percent okra might be suitable combination for higher productivity and economic return at Joydebpur and Burirhat, respectively.
