A study was conducted to determine the effect of low cost drip tape irrigation system on yield and economics of sweet corn in comparison to conventional inline drip irrigation and surface irrigation systems during 2013-14 at Coimbatore, India. The treatment comprises of two drip irrigation systems with three irrigation levels viz., 75, 100 and 125% of pan evaporation (PE) from Class A Pan evaporimeter. Plant height, fresh cob length, girth, number of kernels per cob and single fresh cob weight and yield were higher at 125% PE in conventional in line drip irrigation system and it was statistically at par with drip irrigation at 125% PE in low cost drip tape irrigation system. Water saving was 36, 49 and 62% at 125, 100 and 75% PE, respectively under conventional in line drip irrigation system and drip tape irrigation system as against the surface irrigation. The cost of low cost drip tape system was 68% lower than the conventional inline drip system. The results of the research indicated that based on net income, B:C ratio and GM/TMV ratio, adoption of low cost drip tape irrigation system at 125% PE was found to be best for small and marginal farmers with substantial yield and income compared to conventional inline drip system.Bangladesh Agron.

The Cost

Drip irrigation has long been proven beneficial for fruit and vegetable crops in Pakistan, but the only barrier in its adoption is the high cost of installation for small landholders, which is due to overdesigning of the system. In the present study, the cost of a conventional drip irrigation system was reduced by redesigning and eliminating the heavy filtration system (i.e., hydrocyclon, sand media, disc filters (groundwater source), pressure gauges, water meters, and double laterals).Purchasing the drip system from local vendors also reduced the cost. Field trials were conducted during 2015 and 2016 to observe the productive and economic effects of low-cost drip irrigation on vegetables (potato, onion, and chilies) and fruits (olive, peach, and citrus). The low-cost drip irrigation system saved 50% cost of irrigation and increased 27–54% net revenue in comparison with the furrow irrigation system. Further, water use efficiency (WUE) was found from 3.91–13.30 kg/m3 and 1.28–4.89 kg/m3 for drip irrigation and furrow irrigation systems, respectively. The physical and chemical attributes of vegetables and fruits were also improved to a reasonably good extent. The present study concluded that low-cost drip irrigation increased the yield by more than 20%, as compared with traditional furrow irrigation, and thus, it is beneficial for the small landholders (i.e., less than 2 hectares).

Utilization of the potential of marginal land with adequate water and nutrients is an important factor in increasing corn production. However, high porosity levels and low nutrient levels cause growth and production of corn is not optimal. The aim of this research is to obtain an irrigation technique combined with efficient fertilization in the sweet corn cultivation system in marginal land. The field research was carried out at Faculty of Agricultural Research Wedomartani, Depok Sleman Yogyakarta. The study was conducted from September 2019 to February 2020. The research aims to get best sweet corn line at various concentrations of liquid organic fertilizer in marginal land with a drip irrigation system.The research was arranged in a completely randomized design (CRD) with 3 replications. The first factor is sweet corn lines, which consists of 9 levels, namely, G1 (5042B), G2 (KD-11), G3 (KD-13), G4 (SB-11), G5 (SB-13), G6 (SB-14), G7 (SB-16), G8 (SB-21), and G9 (SB-22). While the second factor is the irrigation system combined with fertilization (fertigation) which consists of 3 levels, namely the drip irrigation system with a concentration of liquid supplement fertilizer 2 cc / L, 3 cc / L and 4 cc / L. The results showed that the drip fertigation system with a concentration of POC 3 cc / L was able to give a better effect on plant height and leaf length in sweet corn. SB / 1-3 lines was the best lines as prospective parents for making hybrid lines for plant height, leaf length, number of leaves and cob length.Keywords: lines, liquid organic fertilizer, sweet corn, marginal land, irrigation system

[email protected]  1 RESUMO A irrigação localizada envolve os sistemas onde a água é aplicada diretamente sobre a região da raiz, em pequenas intensidades, mas com alta freqüência, a fim de manter a umidade do solo na zona radicular próxima à capacidade de campo, sendo de grande importância no cenário agrícola brasileiro, com aplicações voltadas principalmente para a fruticultura, horticultura e fertirrigação. Os sistemas de irrigação localizada de alta frequência são os mais afetados pela obstrução dos emissores decorrente da contaminação da água. Este trabalho objetivou avaliar a obstrução de emissores em um sistema de irrigação por gotejamento usado na cultura da uva por 5 anos, com fertirrigação, utilizando água salina de poço profundo, afim de apontar possíveis causas e sugerir soluções que permitam o uso otimizado da água de irrigação. Como referência, os tubos gotejadores inicialmente foram submetidos a 360 h de irrigação com água do Serviço Autônomo de Água e Esgoto de Juazeiro-BA (SAAE) e posteriormente com água do Rio São Francisco.  O trabalho foi desenvolvido no Laboratório de Irrigação, no Campus de Juazeiro/BA, da UNIVASF. A estatística foi à descritiva, por medidas de tendência central e por medidas de dispersão de dados. Como principais resultados têm-se que os emissores com cinco anos de uso na fertirrigação, apresentaram inicialmente um grau de entupimento de 16,5%, bem superior se comparado com o mesmo tubo gotejador novo, em torno de 7%; com um aumento nos valores para 18% e 11%, respectivamente. Foi verificado que a água salina causou uma obstrução parcial maior que a água tratada do abastecimento. PALAVRAS CHAVE: grau de entupimento, água salina, uniformidade de aplicação.  NASCIMENTO, R.

F.DYNAMICS OF OBSTRUCTION OF THE ISSUER USED IN GRAPE CULTURE USING SALINE WATER WELL UNDERGROUND    2 ABSTRACT The drip irrigation involves irrigation systems where water is applied directly to the root area in small intensities, but with high frequency in order to maintain soil moisture in the root zone close to field capacity, and is of great importance in the Brazilian agricultural scenario, with applications geared mainly for fruits, vegetables and fertigation. High frequency localized irrigation systems are the most affected by obstruction of emitter due to water contamination. This study evaluated the emitters obstruction in a drip irrigation system used in wine growing for 5 years, with fertigation using saline water from deep well, in order to identify possible causes and suggest solutions to the optimal use of water irrigation. As reference, the drip irrigation system was subject to 360 h of irrigation with water and then with SAAE water from São Francisco River. The work was developed in the Irrigation Laboratory in the campus of Juazeiro / BA, UNIVASF. Statistical analysis was descriptive, for measures of central tendency and data dispersion measures. And the main results is that for the issuing company with five years of use in fertigation, initially, the proportion was 16.5% clogging, much higher compared to the same new dripline, around 7%; with 18% and 11% increase in  values for, respectively. It has been found that the saline water caused a partial obstruction greater than that of the treated water supply. Keywords: degree of clogging, salt water, uniformity of application.

The localized irrigation is the artificial application of water to the root zone of plants for the purpose of supplying the essential moisture requirement for plant growth. The system makes the production and availability of food crops, citrus and vegetables possible throughout the year on small and medium scale basis at an affordable cost. In places and periods of water scarcity, low-cost drip irrigation can be used for the economic growing of vegetables, citrus and food crops all –round the year. This paper aimed at developing a low-cost drip irrigation system to empower the small and medium scale farmers to produce crops during offseason at minimum operational cost with less human efforts. The field area of 126.4 m2 was properly cleared, stumped, ploughed, harrowed and leveled. The leveling was carried out to allow unobstructed flow and evenly distribution of water to the root of plants. The system does not only reduce water loss but also conserve water during the period of scarcity. The controlled moisture available to the plant at low soil tension results in faster growth, higher yields, better quality and more environmentally and health friendly. The system improves the penetration of water into problematic soils and reduces substantially deep percolation and runoff losses. The system also saves water, money, time and makes provision for all- season farming. The topography of the field was flat with its suitable soil texture, texture, retention capacity and pump for this work was designed and selected to be 1 hp. The system was developed using a simple principle of water flow through gravity to drip out water at regulated interval to irrigate farmland. The drum has 214 litres capacity and 121 emitters. The total cost of production was estimated to be ₦50, 790 which is affordable by small and medium scale farmers.

Water Tables

Three vegetable irrigation systems, semi-closed subirrigation (seepage), fully enclosed subirrigation (seepage), and drip irrigation, were evaluated for use on sandy soils with naturally high water tables to determine comparative irrigation costs for tomato production. Investment, fixed (ownership), and variable (operating) costs were estimated for each irrigation system. The investment costs of the drip irrigation system were significantly greater than those for the semi-closed and fully enclosed irrigation systems. The variable costs, however, for the semi-closed system were considerably less than those for the fully enclosed and drip irrigation systems. The semi-closed irrigation system, therefore, was determined to be the least-cost tomato irrigation system under present fuel cost and nonlimiting water supply conditions.
