Use Efficiency

Although water-saving measures are increasingly being adopted in orchards, little is known about how different irrigation methods enhance water use efficiency at the root system level. To study the allocation of water sources of water absorption by cherry roots under two irrigation methods, surface irrigation and drip irrigation, oxygen isotope tracing and root excavation were used in this study. We found that different irrigation methods have different effects on the average δ18O content of soil water in the soil profile. The IsoSource model was applied to calculate the contribution rate of water absorption by cherry roots under these irrigation methods. During the drought period in spring (also a key period of water consumption for cherry trees), irrigation water was the main source of water absorbed by cherry roots. In summer, cherry roots exhibited a wide range of water absorption sources. In this case, relative to the surface irrigation mode, the drip irrigation mode demonstrated higher irrigation water use efficiency. After two years of the above experiment, root excavation was used to analyze the effects of these irrigation methods on the distribution pattern of roots. We found that root distribution is mainly affected by soil depth. The root system indexes in 10–30 cm soil layer differ significantly from those in other soil layers. Drip irrigation increased the root length density (RLD) and root surface area (RSA) in the shallow soil. There was no significant difference in root biomass density (RBD) and root volume ratio (RVR) between the two irrigation treatments. The effects of these irrigation methods on the 2D distribution of cherry RBD, RLD, RSA and RVR, which indicated that the cherry roots were mainly concentrated in the horizontal depths of 20 to 100 cm, which was related to the irrigation wet zone. In the current experiment, more than 85% of cherry roots were distributed in the space with horizontal radius of 0 to 100 cm and vertical depth of 0 to 80 cm; above 95% of cherry roots were distributed in the space with the horizontal radius of 0 to 150 cm and the vertical depth of 0 to 80 cm. Compared with surface irrigation, drip irrigation makes RLD and RSA more concentrated in the horizontal range of 30–100 cm and vertical range of 0–70 cm.

Irrigation Systems

Methods of irrigation are reviewed, including surface irrigation, sprinkler irrigation and drip irrigation, and the problems of these systems with regard to the quality of the water used are described. Surface irrigation does not suffer much from water quality problems, but both sprinkler irrigation and drip irrigation systems are more affected, the main problem being clogging of pumps, pipes and orifices. Clogging is usually due to a combination of suspended matter, chemical precipitation and biological growth. Current solutions through water treatment, and associated problems with this, are described, with examples given of typical strainers and filters. The key to the solution of clogging problems is a proper match between water quality of the source and within the distribution system, and the type ot treatment to be used, therefore, proper water quality monitoring is recommended. Direct granular filtration is the most preferaDle treatment process for drip irrigation systems.

A field experiment was conducted at Tamil Nadu Rice Research Institute, Aduthurai, Tamil Nadu during Summer, 2013 and 2014 to study the response of blackgram varieties to different levels of irrigation through applied sprinkler system. Four levels of irrigation I1 - 50 per cent pan evaporation through sprinkler irrigation, I2 - 75 per cent pan evaporation through sprinkler irrigation, I3 - 100 per cent pan evaporation through sprinkler irrigation and I4 - Surface irrigation in main plot and three blackgram varieties viz., ADT 5, PBG 4 and VBN BG 6 were evaluated in split plot design with three replications. Sprinkler irrigation at 100% pan evaporation in variety ADT 5 gave significantly better growth and yield attributes and higher grain yield of 1217 kg/ha which was at par with surface irrigation method in ADT 5 variety (1184 kg/ha). Surface irrigation method utilized higher amount of irrigation water of 428.1 mm and 413.6 mm, whereas, sprinkler irrigation at 100% pan evaporation utilized minimum amount of irrigation water of 329.2 mm and 308.7 mm during summer 2013 and 2014, respectively. Water saving under sprinkler irrigation at 100% pan evaporation was 23.1% and 25.4% as compared to surface irrigation method during summer 2013 and 2014, respectively.

The present study on Performance evaluation of Sweetcorn with different levels of Irrigation and nitrogen through drip during post monsoon season at Rajendranagar, Hyderabad, India was conducted for two years at Maize Research Centre, Agricultural Research Institute (ARI), Rajendranagar, Hyderabad to assess the influence of different levels of irrigation and nitrogen on performance of sweetcorn hybrid. Randomized block design with factorial concept was used in the study and the experiment was replicated thrice. The treatments used were two factors. Factor I was five irrigation levels viz., I1: Drip irrigation at 60% E pan, I2: Drip irrigation at 80% E pan, I3: Drip irrigation at 100% E pan, I4:Drip irrigation at 120% E pan andI5: Surface irrigation at IW/CPE- 1.0 and Factor II was four nitrogen levels in kg ha-1 viz., N1: 120, N2: 160 N3: 200 N4: 240. Pooled mean of two years revealed that, drip irrigation with 120% E pan which was on par with 100% E pan showed significantly better crop performance in terms of growth characteristics like plant height, Leaf Area Index and dry matter production and both were superior to drip irrigation of 80 and 60% E pan as well as surface irrigation method. Among the yield attributes, cob girth and 100 seed weight were not influenced either with irrigation or nitrogen and their interaction. Cob length, number of seeds row-1, green cob and fodder yield were higher with drip irrigation of 120% E pan but were on par with 100% E pan. Among the different nitrogen levels, nitrogen at the rate of 240 kg ha-1recorded significantly higher growth parameters, yield attributes, green cob and fodder yield but it was on par with 200 kg ha-1 and both were superior over 160 and 120 kg N ha-1. Drip irrigation of 100% E pan and a nitrogen level of 200 kg ha-1 resulted in higher gross and net returns and benefit cost ratio compared to other irrigation and nitrogen treatments. From the study, drip irrigation of 100% E pan with 200 kg N ha-1is recommended for getting higher yields and net income in sweetcorn hybrid grown in Southern Agro climatic zone of Telangana, India.

Rooftop Agriculture

Urbanization and population growth have led to urban areas with a substantial concrete surface compared to adjacent rural areas, creating challenges regarding fresh food, water security, and the need for agricultural land. Climate change affects the rainfall pattern and ground water in urban areas, so the gradual growth of urban rooftop agriculture (URTA) is an increasing trend for the owners of residential buildings. URTA is increasing in the form of private initiatives, but without consideration of efficient water management techniques and application of other related inputs. URTA differs substantially from traditional agriculture in terms of sunshine, thermal regime, the moisture dynamics of a concrete roof top, etc. Considering these aspects of URTA, an effective, efficient, science-based and economically viable irrigation method is necessary to popularize this approach and consequently increase the productivity of crops. With this in mind, the drip irrigation method is considered for the cultivation and determination of water productivity for selected species of plants such as the Bottle Gourd, Tomato, Chili, and Brinjal in the URTA, which was also compared to the traditional irrigation approach. This is why groundwater and green (grey and rain) water were considered as the source of irrigation during the dry season, based on the daily crop evapotranspiration and moisture content of the plant growing medium. For this reason, ET0 of the selected crops was measured using the CROPWAT 8.0 model. The results of this study revealed that the optimum irrigation water requirement of any crop in URTA is around 54% access (ETc), and 46–64% of access irrigation water is used by the traditional method compared to the drip irrigation method. The study reported that with drip irrigation with potable water, the yield was increased by 21.43–22.40% and rain and grey-water also increased yield by 31.87–33.33% compared to container and traditional pipe irrigation. It was also found that the water qualities of mixed water (grey and rainwater) are in an acceptable range limit for irrigation. As a result, urban planners, city dwellers, and researchers can formulate appropriate plans to cultivate different species of plants through this water saving irrigation method using green water, and should explore the concept of water-smart URTA technologies as organic inventions embedded in these results.

The field experiment was conducted to study the effect on yield, water use, economics and storability of onion during rabi season of 2014-17 at Interfaculty Department of Irrigation Water Management, MPKV Rahuri. The experiment comprised of 100, 80 and 60 per cent recommended dose of fertilizer through fertigation, irrigation N and K through drip and P application in soil, drip with conventional fertilizers application in soil, surface irrigation with conventional fertilizers as control and micro-sprinkler irrigation with 100 % RDF through fertigation. The drip irrigation was beneficial than surface irrigation in increasing the yield (78.8 %) and saving the fertilizer. The total seasonal water requirement in drip irrigation was 480.3 mm compared to 807.2 mm in surface irrigation. The drip irrigation with 100 % RDF though fertigation was profitable higher net seasonal income of Rs. 2,74,445 per ha, compared to control (Rs.1,41,955 per ha) with B:C of 4.62 and water productivity of Rs. 566 per mm of water used. The micro-sprinkler irrigation with 100 % RDF through fertigation had significantly maximum total storage losses of 21.10 per cent followed by surface irrigation with 100 % RD of conventional fertilizer (19.86 %) and drip irrigation with 100 % RDF through fertigation. The results revealed that drip fertigation with 100 % RDF through fertigation in 13 weekly splits as per schedule is the best treatment to improve the yield, economical returns and storability of onion (var. N-2-4-1) cultivated in silty clay loam soils of Western Maharashtra.

Alternate drip irrigation (ADI) is a useful irrigation method for water conservation and the regulation of soil quality; however, knowledge about the underlying mechanism of soil-root-bacterium interactions is limited. To determine the mechanism by which ADI transforms soil nutrients and thereby promotes plant growth and to provide a basis for the reasonable selection of drip irrigation methodology, the present study investigated the effects of ADI on the composition and potential function of the bacterial community in tomato rhizosphere soils under greenhouse conditions and analyzed the soil-root-bacterium interactions under ADI. The results revealed that, compared with the soils of the plots treated with surface drip irrigation with plastic film mulching (DI-PFM), the soils of the plots treated with ADI presented an optimized bacterial community structure and optimized soil nitrogen (N) and phosphorus (P) metabolism. The soil available N contents under ADI with lower irrigation limits of 50%, 60%, and 70% of field capacity (A50, A60, and A70 treatments, respectively) were 1.48, 2.19, and 1.91 times greater than those under DI-PFM, respectively; similarly, the soil available P contents were 1.49, 1.65, and 2.91 times greater; the total phosphorus (TP) contents in the tomato roots were 1.06, 1.94, and 1.59 times greater, respectively; and the TP contents in the tomato plants were 1.03, 1.75, and 2.84 times greater, respectively. In addition, the total nitrogen (TN) contents in the tomato roots under ADI with lower irrigation limits of 60% and 70% of field capacity were 1.07 and 1.14 times greater than those under DI-PFM, and the TN contents in the tomato stems were 1.21 and 1.12 times greater than those under DI-PFM. However, compared with DI-PFM, ADI improved tomato yields by 24.23% under only 70% of field capacity. Therefore, ADI significantly enhanced soil-root interactions and stimulated the activation of soil N and P, but only a proper low soil moisture content (SMC) led to significantly increased tomato yields.
