“…Application efficiency (70–90%) was recorded for maize under surface drip irrigation, where losses are very minimal (Ashraf, 2012). Similar results on the enhancement of efficiency have also beenreported by several researchers (Bibe et al, 2017; Fan et al, 2017; Hassanli et al, 2009; Kadasiddappa & Rao, 2018; Qin et al, 2016; Tian et al, 2017; Valentín et al, 2020; Wang, Li, et al, 2021; Wang, Xiao, et al, 2021). There was a WP enhancement of 47% and water saving of 22% with 96% irrigation efficiency by using perforated pipes compared to the conventional method (Nasir et al, 2014).…”

Maize (Zea mays L.) is the third most important cereal crop produced globally after wheat and rice and provides the basic raw materials for starch, oil, protein, alcoholic beverages, food sweeteners and fuel. It is grown on an area of 201.98 Mha worldwide, with an average productivity of 5.75 t ha−1. Maize is mostly grown during the rainy season, but it performs better during the winter season with irrigation and resource conservation techniques. The average productivity of maize during the rainy and winter seasons is 4.3 and 6.2 t ha−1, respectively. The total production is as low as 2.7 Mt in Nepal to 362.78 Mt in the USA. Maize performs better under the furrow and drip irrigation methods, and the range of water requirements is between 425–789 and 351–685 mm, respectively. Plastic and straw mulching has enhanced irrigation water use efficiency up to 34.0–47.2 and 15.3–24.1 kg ha−1 mm−1, respectively. The crop coefficients, Kc values, for maize crops ranges between 0.2 and 1.2. Of the different methods of irrigation, the drip irrigation method enhances the maize yield by 28% and plays a great role in corn yield. This paper discusses various strategies for enhancing global maize yield.

“…Rice-wheat rotation is regarded as the principal cropping system in South Asian countries and the system is also widely prevalent in India and Himachal Pradesh (HP) (Mahajan and Gupta, 2009). In India around 12.3 million hectare (M Ha) is under Paddy-W heat farming system (PWFS) and 85 per cent of total area under this crop rotation system fall in the Indo-Gangetic plains (Ladha et al, 2003) and optimum irrigation facilities can improve the yield (Kadasiddappa and Rao, 2018) and technical efficiency (Sharma and Sekhon, 2021) which have a positive impact on total produce from this system. However, this system has given rise to issues like declining underground water table, ground water pollution, spread of diseases and insect-pest, degrading soil structure and declining soil health and declining crop response (Bajwa, 1993;Kukal and Aggarwal, 2003;Tyagi et al, 2012;Bhatt et al, 2016).…”

Background: Marginalisation of Indian agriculture, due to increase in marginal and small agricultural households, brings the focus back on subsistence agriculture. Among other things, understanding the economics of subsistence agriculture will go a long way in making its practice viable by making sure the help that these subsistence farmers need are provided. Therefore, the present study attempts to study the economics of paddy-wheat and maize-wheat rotation cropping system practiced by subsistence farmers of Himachal Pradesh whose agriculture sector is known for its diversification towards high value crops. Methods: The study has used survey data collected from 60 randomly selected households from Rait block of district Kangra, Himachal Pradesh. 30 households practicing paddy-wheat rotating cultivation are selected from Boh and Drini village and 30 households doing Maize-Wheat rotating cultivation are from Machhlini, Panjol, Khridi, Rulede and Lahri village. The study is based on primary data which has been collected through a pre-tested schedule. Using the primary data, we have brought out factors other than self-consumption needs that determines choice between two farming systems and also two group of farmers are compared in terms of productivity, cost of cultivation and net returns from cultivation. Result: Our study found that irrigation facilities play an important role in the choice between the two cropping systems. Return from cultivation is negative for both groups of farmers if imputed value of family labour is included. Performance of paddy-wheat farmers is significantly better than maize-wheat farmers in economic terms in the study area.

“…Increasing water scarcity affects the irrigation practices in arid and semi-arid regions. Drip Irrigation (DI) system is best alternative to other irrigation systems (Kadasiddappa and Rao, 2018). In DI, water is applied adjacent to the plant root to wet only the active root zone to maintain sufficient moisture for the plant.…”

Background: A properly designed drip irrigation system increases the efficiency of irrigation water and its design is based on the soil wetting pattern. Methods: In this study, a numerical model has been developed using one-dimensional Richard’s Equation to simulate soil wetting pattern under drip irrigation. A fully implicit finite-difference scheme has been used to solve the governing equations with suitable initial and boundary conditions. An experiment was also conducted to analyse the wetting pattern in sandy loam soil. Wetting front computed by numerical model has been compared with the experimental wetting front at different time interval of drip irrigation system. The present model is also validated with the results available in the literature. Result: Statistical indices - root mean square error, percentage bias and coefficient of determination have been used to evaluate the model’s performance. The computed results are closely matched with the and experimental results with RMSE is less than 3, PBIAS less than 6% and R2 greater than 0.96 and also with the earlier models with RMSE is less than 0.01, PBIAS less than 4% and R2 greater than 0.98, It shows that the present model can simulate soil wetting pattern in the drip irrigation system.
