Field experiments were conducted during winter seasons of 2010–11 and 2011–12 at Bikaner (Rajasthan) to study the effect of bioregulators viz., TGA and N-acetyl cystein under different drip irrigation levels on yield, yield attributes, water use and water use efficiency of fenugreek. The highest plant height (69 cm) and yield attributes viz., branches plant-1 (7.6), pods plant-1 (46.3), pod length (13.5 cm), seed pod-1 (16) and test weight (12.7 g) were recorded with 100% ETc + TGA (200 ppm). Further, 80% ETc + TGA (200 ppm), and 100% ETc + N-acetyl cystein (both 10 and 20 ppm) and 100% ETc + TGA (both 100 and 200 ppm) produced comparable plant height. However, 80% ETc + N-acetyl cystein (both 10 and 20 ppm), 80% ETc + TGA (both 100 and 200 ppm), 100% ETc + N-acetyl cystein (both 10 and 20 ppm), 100% ETc + TGA (100 ppm) and 100% ETc + TGA (200 ppm) recorded at par branches plant-1, pods plant-1, pod length and test weight of fenugreek. Highest seed and biological yield of fenugreek were recorded with 100% ETc + Nacetyl cystein (20 ppm), which was at par with 100% ETc + N-acetyl cystein (10 ppm) and 100% ETc + TGA (both 100 and 200 ppm). Maximum water use recorded at 100% ETc with or without bioregulators, whereas maximum water use efficiency was recorded with 60% ETc + N-acetyl cystein (20 ppm) followed by 60% ETc + N-acetyl cystein (10 ppm).

An investigation was carried out on sandy loam soils of semi arid regions of southern Telangana to analyze the potential of drip irrigation along with mulch on mango fruit yield, water and nutrient use efficiency. The treatments of present study were comprised of two levels mulching (M0-without mulch and M1-with mulching), with silver Polyethylene of 100 micron thickness were used and two levels of irrigation (I1 -75% and I2 100% ETc through drip), here irrigation levels and mulching together constituting four treatment combinations with five replications under 2x2 factorial randomized block design and the treatment combinations are: I1M0-75% ETc + No mulching, I1M1- 75% ETc + with mulch, I2M0- 100% ETc + No mulching and I2M1- 100 % ETc + with mulch.  The study revealed that drip irrigation 100% ETc along with silver polythene mulch showed better performance in terms of yield, water use efficiency, nutrient use efficiency as well as economics. Maximum yield of 89.11 kg tree-1 combination of 75 % ETc + with mulching has proven the maximum water use efficiency (5.54 g liter-1 water consumption) and fertilizers use efficiency (0.89 q kg-1 fertilizer application) however along with maximum net return of 400973. 90 rupees ha-1, net return of 346873.90 ha-1 per hectare and B: C ratio of 7.41 was recorded in I2M1 (100 % ETc + with mulch). So the experiment suggests that drip irrigation along with mulch has the potential to provide greater benefit by optimizing the use of water resources. But the interaction of 75 % ETc + with mulching has proven the maximum water use efficiency (6.28 g liter-1 water consumption).

A three-year field experiment was conducted at the Agricultural Research Station of Mandor, Jodhpur, Rajasthan, under arid climatic conditions in the rabi season of 2016–2019 with the objectives of evaluating the effect of drip irrigation and fertigation levels on cumin plant growth, yield, oil content, water-use efficiency, and water productivity. The pooled data revealed that the drip irrigation at 0.6 cumulative pan evaporation (CPE) recorded significantly higher plant height (31.4 cm), umbels plant−1 (50.4), umbellates umbel−1 (5.07), seeds umbel−1 (5.34), test weight (4.60 g), seed yield (1063 kg ha−1), gross return (₹ 172,600 ha−1), net return (₹ 113,500 ha−1) and benefit, and cost ratio (2.9) over drip fertigation at 0.4 CPE and surface irrigation with 0.8 CPE. The fertigation with 80% recommended dose of fertilizer (RDF) being at par with 100% RDF recorded a significantly higher number of umbels plant−1 (50.0), umbellates umbel−1 (5.03), seeds umbellate−1 (5.24), test weight (4.67 g), seed yield (1052 kg ha−1), gross return (₹ 170,900 ha−1), net return (₹ 111,700 ha−1), and benefit cost ratio (2.9) over fertigation with 60% RDF and control. Maximum water-use efficiency (5.7 kg ha−1 mm−1) and water saving (39.04%) was observed under drip irrigation at 0.4 CPE followed by 0.6 CPE (4.8 kg ha−1 mm−1 and 18.86%, respectively).

The experiment was laid out in a split plot design with 12 treatments consist of three irrigation regimes viz.,drip irrigation scheduled at 0.8 Epan (I1), 1.0 Epan (I2) and 1.2 Epan (I3) as main plots and four NK fertigation levels of 75% recommended dose of NK (F1- N112.5 K75), 100% recommended dose of NK (F2- N150 K100), 125% recommended dose of NK (F3- N187.5 K125) and 150% recommended dose of NK (F4- N225 K150) as sub plot and replicated thrice. yield attributes were significantly higher in irrigation scheduled at 1.2 Epan than 1.0 and 0.8 Epan. Fruit yield was significantly higher in drip irrigation scheduled at 1.2 Epan (83.90 t ha-1) than 1.0 Epan (68.80 t ha-1) and 0.8 Epan (59.50 t ha-1). Yield attributes were significantly higher at 150% recommended dose of NK than 75% recommended dose of NK. Fruit yield was significantly higher at 150 % recommended dose of NK (76.70 t ha-1) than 75% recommended dose of NK (60.30 t ha-1) and onpar with both 125% and 100% recommended dose of NK. Water use efficiency was higher in drip irrigation scheduled at 0.8 Epan (28.6 kg m-3) followed by 1.2 Epan (27.2 kg m-3) and 1.0 Epan (26.6 kg m-3). 150 % recommended dose of NK registered significantly higher water use efficiency (30.1 kg m-3) than 75% recommended dose of NK (23.5 kg m-3). It was recommended that application of 1.2 Epan irrigation and 150 kg N, 100 kg K2O ha-1 by fertigation for maximization of yield.

Jujube tree yields in dryland saline soils are restricted by water shortages and soil salinity. Converting traditional flood irrigation to drip irrigation would solve water deficit and salt stress. The root distribution reacts primarily to the availability of water and nutrients. However, there is little information about the response of jujube roots to the change from flood irrigation to drip irrigation. In this context, a two–year experiment was carried out to reveal the effects of the change from long–term flood irrigation to drip irrigation on soil water, root distribution, fruit yield, and water use efficiency (WUE) of jujube trees. In this study, drip irrigation amounts were designed with three levels, i.e., 880 mm (W1), 660 mm (W2), 440 mm (W3), and the flood irrigation of 1100 mm was designed as the control (CK). The results showed that replacing flood irrigation with drip irrigation significantly altered soil water distribution and increased soil moisture in the topsoil (0–40 cm). In the drip irrigation treatments with high levels, soil water storage in the 0–60 cm soil layer at the flowering and fruit setting, and fruit swelling stages of jujube trees increased significantly compared with the flood irrigation. After two consecutive years of drip irrigation, the treatments with higher irrigation levels increased root length density (RLD) in 0–60 cm soil depth but decreased that in the 60–100 cm depth. In the horizontal direction, higher irrigation levels increased RLD in the distance of 0–50 cm, while reducing RLD in the distance of 50–100 cm. However, the opposite conclusion was obtained in W3 treatment. Additionally, in the second year of drip irrigation, W2 treatment (660 mm) significantly improved yield and WUE, with an increasing of 7.6% for yield and 60.3% for WUE compared to the flood irrigation. In summary, converting flood irrigation to drip irrigation is useful in regulating root distribution and improving WUE, which would be a promising method in jujube cultivation in arid regions.

Acmella oleracea (L.) R.K. is a native Amazon vegetable, known as jambu, which is widely used in regional cuisine and has aroused the interest of the pharmaceutical and cosmetic market. Thereby, this work aimed to study the effect of different soil water tensions and nitrogen rates on Jambu cultivation in the State of Pará. The experiment was conducted in a greenhouse for 30 days in 2016 testing Jamburana cultivar in a 10 × 10 cm spacing in the experiment. The experimental design was based on randomized blocks in a 4 × 4 factorial scheme with three replications. The treatments consisted of four soil water tensions (12, 18, 24 and 30 kPa) adjusted using drip irrigation, and four doses (0, 50, 100 and 150 kg ha-¹) of nitrogen. The analyzed variables were fresh mass, plant height, productivity and water use efficiency. There was no interaction between soil water tensions factors and nitrogen rates for all variables. The results showed that the best water tension in the soil and nitrogen dose that provided better development and productivity of jambu were 18 kPa and 79 kg ha-¹, respectively.
