Solid and liquid wastes from feces and fish feed residues can affect water quality, which in turn affect fish physiological processes, behavior, growth and mortality. So it is necessary to have water quality management in the aquaponic system. This study aimed to observe the growth of lettuce and water spinach as biofilters in silver catfish culture (Pangasius sp) using aquaponic system. The study was conducted at the Laboratory of Fisheries, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, from March to April 2018. This was an experimental study using Randomized Block Design (RBD) with two treatments and six repetitions to compare between combination of silver catfish and water spinach with silver catfish and lettuce combination. The parameters observed were fish growth, fish survival, increase in  stem length, and increase in the number of leaves. The results show silver catfish and water spinach combination produced the highest crop with a stem length of 38.7 cm and more leaves with an addition of 16 leaves. A higher absolute growth of 7.79 grams fish-1 and 100% survival are also seen in this combination. Furthermore, water spinach is more effective as biofilter for aquaponic systems than lettuce.Limbah padat dan cair dari feses dan sisa pakan ikan dapat mempengaruhi kualitas air, yang selanjutnya memengaruhi proses fisiologis ikan, perilaku, pertumbuhan, dan angka kematian. Sehingga perlu adanya manajemen kualitas air pada sistem akuaponik. Penelitian ini bertujuan untuk mengamati pertumbuhan selada dan kangkung sebagai biofilter pada budidaya ikan lele (Pangasiussp) dengan sistem aquaponik.

Abstract Drinker devices can affect feed and water intake, which then affect performance, as well as device cleanliness, water quality and spillage. One hundred and eighteen Holstein male calves (311 ± 1.4 kg and 228 ± 0.6 d of age) were used in a randomized block design to evaluate the effect of drinker device on concentrate and water intake, performance and water spillage during the winter months. Calves were allocated in 6 pens (3 pens/treatment; 19 to 20 calves/pen) with one computerized concentrate feeder and one straw feeder. Pens were assigned to one of the two treatments: one water through (TRO, 35 cm x 35 cm, no pressure was required) or one bowl with nipple facing up (BO, bowl with a 20 cm diameter and 5-cm nipple, bite-style that was activated then animals pressed the nipple). Concentrate and water intake were recorded daily, body weight (BW), drinker device cleanliness, and water spillage (DM of bedding under the drinker) fortnightly, and water quality monthly. Data were analyzed using a mixed-effects model. Final BW, average daily gain, and concentrate intake were not affected by treatment. Apparent water intake tended (P = 0.10) to be greater in TRO (26.5 ± 0.39 L/day) than in BO (25.5 ± 0.39 L/day) and water spillage was lesser in TRO (70.3 ± 1.67 % DM) than BO (75.6 ± 1.67 % DM) pens. No differences in water quality parameters were observed despite cleanliness of TRO was lesser compared with BO devices (83.3 % vs 2.0% had presence of feed, respectively, P < 0.001). Data of the present study are promising; the bowl nipple device reduces 4% apparent water consumption and water spillage with no impairment in animal performance and improving device cleanliness. A replicate trial will be run during summer months to contrast and complete the present study results.

The present work aimed at determining the effects of the association between the periphyton-based system with the bioflocs-based system in the intensive culture of juvenile Nile tilapia (1.56 ± 0.07 g; 72 fish m-3), on variables of water quality, growth performance and effluent quality after 10 weeks. The experiment was arranged in a 2 x 2 factorial randomized block design with four treatments and five repetitions each. The factors tested were the following: ‘underwater structure’ (absence and presence) and ‘adjustment of the C: N ratio of water’ (no and yes). The final fish body weight, specific growth rate and yield were higher (p < 0.05) in the C: N-adjusted tanks. The presence of submerged structures in the tanks had no significant influence on those same variables. It was concluded that the periphyton-based system is not indicated for intensive farming of Nile tilapia, in which there is a high allowance of artificial feed to fish.

Background: Basmati rice is an important cereal crop occupying a unique position in Indian agriculture. More than 90% of global rice is produced and consumed in Asia and plays a crucial role in the entry of mineral nutrients into the food chain. Identification of stable genotypes is of great significance because the environmental conditions vary from season to season and year to year. Methods: Thirty six Basmati rice genotypes were evaluated in four production environments during kharif 2016 and kharif 2017 at two locations Kaul and Uchani to study the G × E interaction for milling, appearance, cooking and eating quality parameters. The genotypes were grown in randomized block design with three replications. Result: Based on the stability analysis of Eberhart and Russell model, genotypes viz., Haryana Mahak 1, Pusa 1826-12-271-4 and HKR 06-434 were found stable across the environments for milling%, grain length before cooking and length breadth ratio before cooking, respectively.

The present investigation was carried out to study the effect of off season soil management practices on yield and quality of turmeric (Curcuma longa L.) cultivars. The experiment was laid out in a Factorial Randomized Block Design with ten treatments in three replications consisted of five off-season land management treatments viz., fallow (S1), summer ploughing 2 times (S2), summer ploughing 1 time (S3), solarization with transparent polyethylene film of 0.05 mm thick for 40 days (S4) and black polyethylene film for 40 days (S5). It was tested with two popular cultivars viz., Curcuma longa -1 CL-1 (V1) and Curcuma longa-2 CL-2 (V2), collected from Erode and Chidambaram. Various yield components were recorded at the time of harvest and were analysed. The yield attributing characters viz., number, length, girth and weight of mother, primary and secondary rhizomes were recorded. The treatment where solarization with transparent polyethylene film of 0.05 mm thick was tested recorded the highest yield and yield attributing characters when compared to other treatments. The same treatment also exhibited the highest fresh rhizome yield per plant, curing percentage and cured rhizome yield. The quality parameters like curcumin, oleoresin and essential oil content were also showed superior performance in the treatment where solarization with transparent polyethylene film of 0.05 mm thick was applied.

The combination of consumer’s ongoing demand for chia (Salvia hispanica L.) alongside the increased demand for regionally produced food products provided the impetus for this study. Its aim was to test if a regional cultivation of new chia genotypes, which were adapted to day lengths greater than 12 hours, is feasible under Central European conditions. Therefore, three early flowering chia genotypes (Sahi Alba 914, W13.1, G8) were cultivated in a randomized block design at two experimental stations in Southwestern Germany (Ihinger Hof, Eckartsweier) over the course of two years (2015, 2016). Mean yields ranged from 100 to 1290 kg ha−1. Mucilage content ranged from 9.5% to 12.2%, while the crude protein content ranged from 17.2% to 25.0%. Crude oil content fell in the range of 30.9–33.7% and the PUFA:SAT ratio ranged from 4.0 to 9.4, whereas the omega6:omega3 ratio varied from 0.27 to 0.5. As chia seed yields surpassed yield levels obtained by their countries of origin and as quality parameters obtained, were in line with the genotypes cultivated in their countries of origin, it can be assumed that a regional chia production in Southwestern Germany offers great potential, being ecologically and economically profitable.

Aim: To evaluate the efficacy of foliar application of Ascophyllum nodosum extract, homobrassinolide, and triacontanol for improving fruit retention, yield, and quality in mango. Methodology: The experiment was laid out in a randomized block design with 10 treatments, comprising Ascophyllum nodosum extract (1000, 3000, and 5000 ppm), homobrassinolide (0.1, 0.3, and 0.5 ppm), triacontanol (1, 3, and 5 ppm), and water as control. Treatments were foliar sprayed at panicle initiation, pea, and marble stages of fruit growth. Observations were recorded on flowering, fruiting, yield, and fruit quality parameters. Results: All the treatments of Ascophyllum nodosum extract and triacontanol exhibited significant improvement in fruit retention, fruit weight, yield, and fruit quality parameters over control. However, 3000 and 5000 ppm Ascophyllum nodosum extract treatments outperformed all the treatments of triacontanol. Plants sprayed with 5000 ppm Ascophyllum nodosum extract recorded the maximum value for fruit retention (48.15, 36.74, 29.48, and 25.76% at 3, 6, 9, and 12 weeks after pea stage, respectively), number of fruits (133.25 per tree), fruit weight (188.84 g per fruit), and yield (25.16 kg per tree), whereas the lowest values were recorded under control. With respect to fruit quality, 3000 ppm ANE produced the fruits with the highest TSS (19.62 °B), whereas the highest TSS/acid ratio was recorded with 5000 ppm ANE (62.29) treatment. Interpretation: In mango, foliar application of Ascophyllum nodosum extract (3000-5000 ppm) thrice at panicle initiation, pea, and marble stages of fruit growth is effective for reducing fruit drop and enhancing quantum and quality of produce.
