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.

Drip method of irrigation (DMI) introduced relatively recently in India has proved to save sizeable water and augment productivity of crops. Studies conducted mostly on high-value fruit crops have confirmed the various benefits of DMI. However, not many studies have brought out the economic and resource impacts of drip irrigation including its benefit–cost pattern using survey data in crops like okra (ladies’ fingers) which is an important vegetable crop in India. In this article, we have made an attempt to fill this gap by using farm survey data collected from a water scarce district of Tamil Nadu state. We found from this study that DMI can reduce about 15 per cent of cultivation cost, save about 47 per cent of water resources and electrical energy, and augment about 49 per cent of productivity of okra over the same crop cultivated under conventional flood method of irrigation (FMI). Farmers cultivating okra under DMI are also able to generate an additional farm business income of ₹72,711/acre over the non-drip adopters. The net present worth and benefit-cost ratio estimated using different discount rates corroborate that investment in drip irrigation is economically highly viable for okra crop cultivating farmers.

A field experiment to assess the effect of  planting methods and sett treatments on quality, nutrient uptake and economics of bajra napier hybrid grass CO (BN) 5 was conducted during 2018-2019 at the Eastern block farm of the Department of Agronomy, Tamil Nadu Agricultural University – Coimbatore, Tamil Nadu. The experimental field was laid out in factorial randomized block design. The main plots were vertical planting (M1) and horizontal planting (M2) and sub-plots were 13 sett treatments. The results on some quality parameters viz., crude protein, crude fibre, crude fat, total ash contents (%), showed non-significant difference on planting methods, sett treatments and their interaction. Among planting methods, vertical planting had registered higher crude protein yield of 1.23 t ha-1cut-1, nitrogen uptake (151 kg ha-1cut-1), phosphorus uptake (23.4 kg ha-1cut-1) and potassium uptake (87.7 kg ha-1cut-1). Among sett treatments, water soaking for 12 hours and 24 hours incubation (S1) significantly registered higher crude protein yield (1.78 t ha-1cut-1), nitrogen uptake (186.8 kg ha-1cut-1), phosphorus uptake (31.9 kg ha-1cut-1) and potassium uptake (108.4 kg ha-1cut-1). In two planting methods, low cost of cultivation ($ 629 ha-1), higher gross return ($ 1227 ha-1), net return ($ 598 ha-1) and benefit cost ratio (1.98) were registered with vertical planting (M1). Similarly, among sett treatments, water soaking for 12 hours and 24 hours incubation (S1) recorded lower cost of cultivation ($ 563 ha-1), higher gross return ($ 1698 ha-1), net return ($ 1135 ha-1) and benefit cost ratio (3.02). With this, it can be concluded that for planting method, vertical planting (M1), and for sett treatment, water soaking for 12 hours and 24 hours incubation (S1) are the recommended practices for achieving better quality, nutrient uptake and economics from bajra napier hybrid grass.

A field investigation was carried out in farmer’s field at Pudhupalayam, TNAU, Coimbatore, during 2015, to improve the productivity of groundnut variety TMV 13 under drip and micro sprinkler fertigation system. The experiment was laid out in randomized block design (RBD) with three replications comprising of 11 treatments. Results indicated that maximum pod yield (3495 kg ha-1), haulm yield (6452 kg ha-1), harvest index (0.351) and shelling per cent (73.95 per cent) were obtained with drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T1). The water saving achieved under drip irrigation was 40.08% and 55.06% at 100% and 75% PE, respectively, whereas, under micro-sprinkler, it was 25.10% and 43.83% at 100% and 75% PE, respectively over surface irrigation. Higher WUE of 19.28 kg/ha-mm recorded under drip irrigation at 75% PE with fertigation at 100% RDF as WSF (T2) followed by drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T1: 15.88 kg/ha-mm). Highest NUE (23.30 kg kg-1 NPK ha-1) was recorded in drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T1). Drip irrigation at 100% PE with fertigation at 100% RDF as WSF (T1) recorded higher gross return (Rs. 254353 ha-1) and net return (Rs.134712 ha-1). Whereas, the benefit cost ratio was highest in micro sprinkler at 100% PE with fertigation at 100% RDF as WSF (T6: 2.41). The margin benefit cost ratio (MBCR) was recorded highest under micro sprinkler at 100% PE with fertigation at 100% RDF as WSF (T6: 2.53) as compared to all other treatments.

The economic feasibility of apartment building complexes is mainly done by using one of the economic analysis methods: present worth, future worth, annual worth, rate of return, or benefit-cost ratio. The cash-flow used is based on the assumption that a certain fraction of the apartments will be sold during the construction period, and the rest equally sold annually over a certain period of time. This model may work sometimes, but its estimated profitability is inaccurate. The actual cash-flow to be used is stochastic. In this paper, we shall use a cash-flow with random separation time between successive sales of apartments after the construction period. We shall find a compact form of the expected present worth, and determine a range for the annual discount rate so that the project is profitable.

The present study attempts to assess the financial feasibility of layer farms of poultry birds in the Chittoor district of Andhra Pradesh, India. In total, 60 farms were considered for the study, with 20 each for small, medium and large size. A pretested questionnaire was used to collect data from poultry farmers. The Net Present Worth is highest for large farms followed by medium and small farms at both 12 and 16% discount rates, proving the economic viability of farms. The Benefit-Cost Ratio and farm size were positively related and the large farms were economically more viable. The internal rate of return is higher than that of the discount rate for all sizes of farms which implies that investment is feasible. Even though the returns are decreased by 10% (Case I) or costs increased by 10% (Case II), the small, medium and large poultry layer farms are economically feasible at both 12% and 16% discount rates as NPV is positive and BCR is greater than 1. But if the returns are decreased by 10% and Costs increased by 10% (Case III), the small farms become financially infeasible at both discount rates, whereas medium farms become financially infeasible at a 16% discount rate only. The large layer farms are economically feasible at both discount rates if the returns are decreased by 10% and Costs increased by 10% (Case III). Based on NPV, BCR and IRR, large layer farms were most profitable followed by medium and small layer farms. The benefits per bird were highest and cost of production was lowest in case of large farms. The study revealed that poultry layer farming is a profitable business in Chittoor district.

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.
