Spray hose is a micro-irrigation system using perforated hose as for micro irrigation. Shallot conventional cultivation requires lots of water and labor man days therefore is more efficient. Shallot cultivation system needs to be developed to increase yield and to reduce production cost. This research was conducted to compare conventional cultivation methods with using Spray hose and polyethylene mulch for shallot production. This research was conducted in a hydromorphic alluvial soil type at the Center for Tropical Horticulture Studies Field Station in Kersana, Brebes, Central Java (S 6 o, 55’, 20.536”; E 108o, 51”, 50618”) from May to July 2016. The experiment was arranged in a randomized complete block design (RCBD) with a single factor and three levels of planting system, i.e. conventional ‘Surjan’ system without mulch, one line spray hose with mulch, and two lines spray hose with mulch, with five replications. The result showed that shallots production using of polyethylene mulch and two-line spray hose had higher yields than the conventional method. In addition, this system is more efficient in terms of labor requirement. Cost Revenue Analysis shows that conventional cultivation R/C ratio was 1.72, one-line spray hose R/C ratio was 1.92, while two-line spray hose was 2.26. This study demonstrated that the use of polyethylene mulch combined with two-line spray hose significantly improved shallot growth and increased bulb production, and more cost efficient.Keywords: R/C ratio, micro irrigation, labor, ‘Surjan’ system, soil drench, fertilizerConclusionIrrigation of shallot with two-line spray hose resulted in a better crop growth and a higher yield than conventional planting system and one-line spray hose for polyethylene mulched shallot.  Conventional planting system using more water and labor requirement than the two other treatments. Combination of  two-line spray hose and polyethylene mulch had the most eficient cost production of shalot compared to the  conventional system and one-line spray hose.

ABSTRACT The banana tree is grown in an extensive tropical region throughout the world, usually by small producers. The present work had the objective of evaluating irrigation systems in banana production in the Açu-RN Valley, aiming at alternatives so that they can be recommended to farmers in the Açu Valley region. The experiment was carried out in the area of the School Farm of the IFRN Campus Ipanguaçu, located in the municipality of Ipanguaçu-RN. The experiment was carried out in a randomized complete block design with subdivided plots and eight replications. The irrigation systems were: irrigation, drip irrigation, micro sprinkler and alternative irrigation. The plots were composed of eight useful plants with spacing in double rows 4 x 2 x 2 m. Eight characteristics related to production were evaluated: bunch mass (MC); number of leaves (NP); number of fruits per cluster (NFC); mean mass of the leaves (MMP); diameter of the fruit of the second seed (DF2P); length of the fruit of the second seed (CF2P); mean fruit mass (MMF); productivity (Prod). The data were submitted to analysis of variance and the means were compared by the Tukey test at 5% of probability. In the first cycle of production the sprinkler irrigation system was the one that presented better results the productivity of the Pacovan banana tree; in the 3rd cycle the alternative irrigation system was the one that showed better results the productivity of the banana tree; where the electrical conductivity correlated with the sodium adsorption ratio in the irrigation water, contributed to a moderate limitation of use.

ABSTRACT The Brazilian Savannah region presents a great potential for the expansion of upland rice crops. However, studies are necessary to identify practices that can improve the crop performance, especially in no-tillage systems. This study aimed to assess the effect of cover crops in association with corn on the development and yield of rice cultivated in rotation and cover fertilized with nitrogen doses. The sprinkler irrigation system was used and the experiment was developed in the 2014/2015 and 2016/2017 harvest years, using a randomized block design, in a 5 × 4 factorial scheme. The treatments consisted of the crop remains combinations of single corn crop, corn + Crotalaria spectabilis, corn + pigeon pea, corn + jack bean and corn + Urochloa ruziziensis, as well as cover nitrogen doses (0 kg ha-1, 40 kg ha-1, 80 kg ha-1 and 120 kg ha-1) in the rice. The cultivation of upland rice in rotation with corn + pigeon pea was favored by the greater soil cover and nitrogen supply via cycling, if compared to the rotation with single corn crop. The intercropped corn + pigeon pea cultivation in the previous summer resulted in a 15 % increase in the yield of rice grains seeded in the rotation, when compared to the single corn crop. The cover nitrogen application positively influenced the grain yield with the maximum estimated doses of 46 kg ha-1 and 105 kg ha-1 of nitrogen, respectively in the 2014/2015 and 2016/2017 harvest years.

The parameters require for maintaining the crop's health and the integrity of the irrigation system has a relation with quality of irrigation water. In Micro irrigation appropriate filtration is very much important to prevent clogging. Filtration unit is one of the main components in micro irrigation system that too, Primary filter is more important to be installed along with the unit, when the water source is from open reservoir and other water sources. Though it is essential, the primary filter is not being installed by the farmers due to its high cost. Hence this study is an attempt to fabricate low-cost filter and to evaluate its performance with different filter media layer. A low-cost primary filter for drip irrigation system is fabricated. Different filter media layer like silex sand (fine silex, coarse silex), pebbles with different sizes are selected. The results revealed that the removal efficiency of filter using silex sand and pebbles were 71% in terms of turbidity, 78% in terms of total suspended solids removal at flow rate of 12 m3 /hr. This fabricated low-cost filter will be cost effective for small farm applications.

The objective of this work was to evaluate physiological and biochemical responses of Pele de sapo melon to different irrigation depths (ID) and bioestimulant rates (BTM) to improve its production efficiency. The experiment was conducted in an experimental field in Juazeiro, BA, Brazil. A randomized block design in split split-plot arrangement was used, with four ID (60, 80, 100, and 120% of crop evapotranspiration – ETc) in the plots; five (BTM) (Stimulate® at 0, 0.6, 1.2, 2.4, and 4.8 L ha-1 applied via irrigation system during the flowering stage and after the fruiting stage) in the subplots; and two crop seasons (hot season, 23 to 39 °C; and cold season, 15 to 30 °C) in the sub-subplots. The plants were under daily drip irrigation and spacing of 2.0 × 0.3 m. The variables evaluated were: gas exchange, water use efficiency, chlorophyll a and b, relative water, sugar, and amino acid contents, and fruit yield. The results showed that the ID of 60% ETc resulted in water deficit, denoted by increases in solute concentrations, whereas the ID of 80% and 100% resulted in plants with good performance for biochemical, physiological, and production parameters in both crop seasons. The hot season, ID of 120% ETc, and BTM of 2.4 L ha-1 are recommended for Pele de sapo melon crops, since they result in the best physiological responses and fruit yields.

<p>Perkembangan varietas-varietas bawang merah di suatu daerah ditentukan oleh keserasian dengan lingkungan, potensi hasil, toleransi terhadap serangan organisme pengganggu tumbuhan (OPT), serta umur dan mutu hasil. Penelitian bertujuan untuk menguji penampilan beberapa klon bawang merah dan hubungannya dengan intensitas serangan OPT penting. Penelitian dilaksanakan di Brebes dan Tegal (Jawa Tengah) dari Bulan Juni sampai dengan September 2011. Perlakuan yang diuji ialah 10 klon bawang merah hasil silangan tahun 2004 dan 2005, serta dua varietas bawang merah sebagai pembanding (Bauji dan Bima Brebes). Rancangan percobaan yang digunakan ialah acak kelompok dan diulang tiga kali. Parameter yang diamati ialah pertumbuhan tanaman (tinggi tanaman, jumlah daun, dan jumlah anakan), hasil panen, dan serangan OPT penting. Hasil penelitian menunjukkan bahwa klon no. 2005/1 dapat beradaptasi dengan baik di Brebes dan Tegal, mampu menghasilkan produksi tertinggi masing-masing sebesar 9,95 dan 17,50 t/ha, mempunyai diameter umbi terbesar (1,87 dan 2,41 cm), bentuk umbi bulat, dan berwarna merah tua, sedangkan klon no. 2004/11 mempunyai pertumbuhan dan  produktivitas yang tinggi, relatif toleran terhadap serangan Spodoptera exigua, Alternaria porri, dan Colletotrichum gloeosporioides, diameter umbi (1,67 dan 1,96 cm), bentuk umbi bulat,  dan berwarna merah tua, sedangkan klon no. 2004/10 dan no. 2005/19 sangat rentan terhadap serangan hama S. exigua, penyakit A. porri, dan C. gloeosporioides. Klon-klon yang mempunyai tingkat serangan rendah/toleran terhadap OPT merupakan klon harapan bawang merah toleran/tahan OPT. Namun demikian, penggunaan pestisida sesuai dengan konsep pengendalian hama terpadu (PHT) masih tetap diperlukan terutama apabila serangan OPT tersebut mencapai ambang pengendalian yang ditetapkan.</p><p> </p><p>The development of shallots varieties in one location depends on the genetic adaptability, yield potential,  tolerance to pest and diseases, harvest date, yield and quality. The aim of study was to evaluate 10 clones and two local clones as check, Bima Brebes and Bauji were conducted in Brebes and Tegal (Central Java) from June to September 2011. The trial were laid out in a completely randomized block design and each treatment was replicated three times. The parameters used for evaluating these clones were plant height, no. of sprout,  no. of leaves, yield and pests and diseases incidence. The results showed that considering overall performance, clone no. 2005/1 gave the highest yield (9.95 and 17.50 t/ha), and diameter of bulb (1.87 and 2.41 cm) in Brebes and Tegal respectively, clone no. 2004/11 produced growth and good yield  and showed tolerance to Spodoptera exigua, Alternaria porri, and Colletotrichum gloeosporioides, bulb diameter (1.67 and 1.96 cm) with dark red color,  while clone no. 2004/10 and no. 2005/19 were identified as the most susceptible clones to S. exigua, A. porri, and C. gloeosporioides. This suggests that some of shallots clones could be good candidates for the new varieties of shallots. However, the use of pesticides in IPM concept were still needed especially if the incidence of pests and diseases reach the action threshold.</p>

Background: Potato (Solanum tuberosum) popularly known as ‘The King of Vegetables’, has emerged as fourth most important food crop in the world after rice, wheat and maize. Indian vegetables basket is incomplete without potato as its, dry matter, edible energy and edible protein makes it nutritionally superior as well as staple food throughout the world. Methods: The experiment during 2016-2018 was laid out in factorial randomized complete block design with three replications to study the effect of bed size on the yield and size of the tuber under different irrigation methods. Results: Maximum yield was obtained in 60cm bed (narrow bed size) whereas in irrigation system drip produced maximum yield. All quality parameters did not influence due to sowing method and irrigation system but chip recovery was more in drip irrigation than furrow system. Maximum yield through interaction was found in drip irrigated 105 cm triple row bed. Around 45-50 per cent water was saved through drip irrigation as compared to furrow irrigation. However, maximum benefit cost ratio was obtained in furrow irrigated 60cm bed size.
