Soil moisture conservation, proper irrigation scheduling and nutrient management are crucial for sustainable cucumber production. A field experiment was set up over two years (2018 and 2019) to investigate the effects of irrigation frequency, black polyethylene mulching, and nitrogen fertilization on cucumber yield, water use efficiency (WUE) and nutrient use efficiency (NUE) at Ikole-Ekiti, Nigeria. The experiment was a 3 x 2 x 2 factorial in a randomized complete block design (RCBD) with a split-plot arrangement and the main plot as drip irrigation frequency: twice per week (I4), three times per week (I5), and four times per week (I6), while the sub-plots were nitrogen fertilization; (no fertilizer, N0 and 180 kg/ha urea, N180) and mulching (no mulch, NM and mulch, M). The highest yield (8.39 and 8.51 t/ha) with the best WUE was obtained from treatment I4MF (F, fertilization), while the lowest (5.81 and 5.79 t/ha) was obtained from I6MF for the respective years. The combination of variables significantly (P<0.05) influenced cucumber yield, WUE, and NUE, and significant correlations were obtained (r=0.87** and 0.85**) between WUE and fruit yield for the study years. The treatment I4MF therefore, could successfully be adopted to reduce water and fertilizer application for improved cucumber yield in the field.

Neste cenário, a irrigação surge como um importante fator de produção, além de promotor da máxima produtividade e da qualidade do produto. O objetivo deste trabalho foi identificar um manejo adequado da irrigação por gotejamento, com minitanque evaporimétrico, para o desenvolvimento e produção do pepino japonês em ambiente protegido. O ensaio foi realizado na Fazenda Experimental da Universidade Federal Rural da Amazônia, município de Igarapé – Açu/PA. Utilizou-se o delineamento em blocos casualizados com cinco tratamentos e quatro repetições, aplicando-se lâminas de 30, 60, 90,120 e 150% baseadas na evaporação do minitanque. Observou-se que de modo geral, tanto a deficiência quanto o excesso hídrico afetaram negativamente as variáveis analisadas. Os melhores índices de produtividade e crescimento foram encontrados nas lâminas de 90 e 120% da ECA e a maior eficiência do uso da água, obtida com as menores lâminas de irrigação, sendo o valor máximo, de 2842,53 kg ha-1 mm-1, encontrado no tratamento com 30 % da ECA.   Palavras-chave: Cucumis sativus L.; evaporação; gotejamento; manejo de água.     RODRIGUES, T.C.A.; LIMA JÚNIOR, J.A.; DE MELO SOUZA, R.O.R.; OLIVEIRA NETO, C.

TECHNICAL FEASIBILITY OF JAPANESE CUCUMBER PRODUCTION SUBMITTED TO DIFFERENT IRRIGATION BLADES     2 ABSTRACT   Water deficiency is usually the factor that most limits the productivity and quality of vegetables. In this scenario, irrigation appears as an important factor of production, besides promoting the maximum productivity and product quality. The objective of this work was to identify an adequate management of drip irrigation, with reduced pan, for the development and production of japanese cucumber in a protected environment. The experiment was carried out at the Experimental Farm of the Rural Federal University of Amazônia, county of Igarapé - Açu - PA. A randomized block design with five treatments and four replicates was used, with slides of 30, 60, 90, 120 and 150% based on the evaporation of a modified pan. It was observed that, in general, both the deficiency and the water excess negatively affected the analyzed variables. The best productivity and growth indexes were found in the 90% and 120% ECA slides and the highest water use efficiency obtained with the lowest irrigation depths. The maximum value was 2842.53 kg ha-1 mm- 1, found in the treatment with 30% ECA.   Keywords: Cucumis sativus L.; drip irrigation; evaporation; water management

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).

Water shortage is a real problem in many parts of the world and finding alternative solutions such as the application of saline water in cropping systems is highly appreciated. Research on drip irrigation and soil salinity is still inadequate, and their effect on crop yield and water use efficiency (WUE) is a huge challenge for small farmers. The present study was conducted in Malir, a semiarid region in the Sindh province of Pakistan. The purpose was to estimate the effects of two different qualities of irrigation water including fresh quality water (IT1 0.56 dS m−1) and saline groundwater (IT2 2.89 dS m−1) on WUE using drip irrigation technology in 2018–19. The experimental design was complete randomized block design (RCBD) with two treatments of irrigation: (1) freshwater (IT1) with 0.56 dS m−1 electrical conductivity and (2) saline water (IT2) with 2.89 dS m−1 electrical conductivity. The average biomass and crop yield under IT1 were 10.2 t.ha−1 and 7.4 t.ha−1, respectively, and were found higher than those under IT2 (7.3 t−1 and 4.2 t.ha−1, respectively). Hence, both the treatments remained equally effective in season 1 as compared to season 2 ( p ≤ 0.05 ). The WUE of bitter melon under IT1 was 1.60 and 1.56 kg.m−3 in seasons 1 and 2, respectively, and was higher than those under IT2 which were observed 1.21 and 1.07 kg.m−3 in seasons 1 and 2, respectively.

On sandy soils, potential N contamination of groundwater resources associated with intensively managed vegetables may hamper the sustainability of these systems. The objective of this study was to evaluate the interaction between irrigation system design/scheduling and N fertilization rates on zucchini production and potential N leaching. Zucchini was planted during Fall 2005 using three N fertilizer rates (73, 145, 217 kg/ha) and four different irrigation approaches. Irrigation scheduling included surface-applied drip irrigation and fertigation: SUR1 (141 mm applied) and SUR2 (266 mm) using irrigation control system (QIC) that allowed time-based irrigation (up to five events per day) and a threshold setting of 13% and 15% volumetric water content (VWC), respectively; Subsurface drip irrigation (SDI) using a QIC setting of 10% VWC (116 mm) combined with surface applied fertigation; and a control treatment with irrigation applied once daily (424 mm). Leacheate volumes were measured by drainage lysimeters. Nitrate leaching increased with irrigation rate and N rate and measured values ranged from 4 to 42 kg N/ha. Use of SDI greatly reduced nitrate leaching compared to other treatments. SDI and SUR1 treatments had no effect on yields (29 Mg/ha). However, SDI had a 15% and 479% higher water use efficiency (WUE) compared to SUR1 and the fixed irrigation duration treatment. Application of N in excess of intermediate N-rate (standard recommendation) did not increase yield but yield was reduced at the lowest N-rate. It is concluded that combining sensor-based SDI with surface applied fertigation resulted similar or higher yields while it reduced both water use and potential N leaching because of improved nutrient retention in the active root zone.

The Indo-Gangetic plain (IGP) is an environmentally susceptible, communally momentous and economically tactical sphere of India where landscape, ground water and soil fertility are threatened by climate change. An increasing water scarcity for rice in the irrigated IGP is urging farmers to espouse water saving technologies such micro irrigation. Rice growing with drip irrigation may substantially reduce irrigation water requirement of rice. In order to make assessment of drip irrigation in rice, a field experiment was carried out at Pantnagar, Uttarakhand in 2017. Rice was established by Direct Seeding in conventional and drip irrigation treatments. The treatments were laid with drip irrigation at 50, 75 and 100% CPE on each 2 and 4 days interval. Two conventional irrigation practices (i.e. absolute control and farmers’ practice) were also included in the study. The experiment was laid out in randomized block design with four replications. Compared with farmers practice, (transplanted and flooded) drip irrigation at 100% CPE on two days interval produced taller shoots and higher yield attributes of rice crop. Rice grown in drip irrigation was found more grain yield than farmers’ practice. Among drip irrigation, 100% CPE on 2 days gap (T5) recorded 45% higher grain yield (5800 kg ha-1) than farmers practice. Similarly, T5 treatment was higher content and uptake of nutrient. However, treatments T3 (50% CPE on 2 days gap) followed by T7 (75% CPE on 4 days interval) had higher water use efficiency. Result, further revealed that fertilizer use efficiency of T5 treatment was found to be higher (23.2 kg grain per kg fertilizer applied). Hence, rice is scheduled with drip irrigation at a tune of 100% CPE on 2 days interval can benefit over sustaining the direct seeded basmati rice productivity. However, there is a demand to examine these benefits of drip irrigation in rice in relation to the viability of adoption by farmers.

Several practices have been adopted to minimize water use and potential N leaching of vegetable production systems, including use of drip irrigation, plastic mulch, and fertigation. However, these practices may not be adequate on sandy soils with poor water and nutrient retention capacities. The objectives of this study were to evaluate the interactive effects of irrigation practices and fertilizer rates on yield, fertilizer requirements, and N-leaching of pepper and tomato production systems. Bell pepper and tomato were planted on plastic mulched to evaluate the effects of three nitrogen (N) fertilizer rates (154, 192, 288 kg·ha -1 N for pepper vs. 166, 208, and 312 kg·ha-1 N for tomato) and three irrigation scheduling methods were evaluated. Depending on sensor readings, soil moisture sensor (SMS) irrigation treatments allowed up to five watering events per day where as for the fixed duration treatment irrigation was applied once a day. For tomato, the effect of subsurface drip irrigation (SDI) was also evaluated. Compared to TIME, use of SMS control system reduced water use by 29& to 44% and 37% to 66% for tomato and pepper, respectively. Tomato yield was significantly higher on SMS and SDI treatments compared to TIME treatments. For pepper yield and biomass accumulation were not affected by irrigation treatments. The average yields were 24.6 and 27.8 Mg·ha-1 of fresh marketable fruits for pepper and tomato, respectively. Nitrogen rate did not affect yield and optimal yield N rate did not affect yield for either crop. On average, SMS treatments increased irrigation water use efficiency 2–3 times compared to TIME treatments for both tomato and pepper.
