Abstract

Gypsum and cow manure potential as ameliorant to increase crop production under salt stress or saline condition. This research aimed to learn the effect of gypsum and cow manure on the uptake of Na, K and the yield of soybean genotypes under saline condition. This research conducted in green house Jatikerto Experimental Farm Faculty of Agriculture, Brawijaya University, from June to September 2014. The research was arranged in a split plot design. The main plot was soybean genotypes consists of two saline susceptible varieties (G1 = Wilis and G2 = Tanggamus) and two saline tolerant genotypes (G3 = genotype IAC, 100/Bur//Malabar and G4 = genotype Argopuro//IAC, 100); sub plot was ameliorant application consists of A0 = without ameliorant; A1 = cow manure (20 t/ha); and A2 = gypsum (5 t/ha). The results of the research showed that Leaf Chlorophyll Index in susceptible varieties and tolerant genotypes were increased with ameliorant application. Accumulation of proline and K/Na ratio in susceptible varieties higher than tolerant genotypes. Ameliorant application on tolerant genotypes increased grain yield higher than susceptible varieties

Abstract

Sweet potato is the main food resources for human life besides that of rice. An experiment to find out the effect of weeding with two kinds of fertilizer on the growth of yield sweet potato (Ipomoea batatas L.) was conducted at UB Agro Techno Park, Jatikerto, Kromengan, Malang, East Java, from April until to 2017. The experiment used a randomized block design with six treatments consisting of G1 (organic fertilizer + weeding 15 days after planting = DAP), G2 (inorganic fertilizer + weeding at 15 DAP), G3 (organic fertilizer + weeding at 15 and 30 DAP), G4 (inorganic fertilizer + weeding at 15 and 30 DAP), G5 ( organic fertilizer + weeding 15, 30 and 45 DAP), G6 (inorganic fertilizer + weeding at 15, 30 and 45 DAP) with three replications. The results showed that weeding three times (15, 30 and 45 DAP) significantly reduced the dry weight of weeds, improved the growth and yield of sweet potato with two kinds of fertilizers.

Abstract

The objective of this research was to study the effect of bacterial isolates on red pepper at the saline condition. The research conducted in the station of Brawijaya University in Jatikerto village, Malang regency. The study used a randomized block design with bacteria isolated from the soil of saline-prone regions of Lamongan, in coastal East Java Indonesia. The treatments consisted of P0: saline soil without bacteria, P1: saline soil + bacteria SN 13, P2: saline + bacteria SN 22, P3: saline soil + bacteria SN 23, P4: saline soil + bacteria (SN 13 + SN 22), P5: saline soil + bacteria (SN 13 + SN 23), P6: saline soil + bacteria (SN 22 + SN 23), and P7: saline soil + bacterial (SN 13 + SN 22 + SN 23). Red chilli variety used was Gada MK F1. The results showed that the application of bacterial isolates increased leaf area, dry weight of roots and shoot. Uptake of N, P, K and Na also increased with bacterial isolate application. The number of fruit and fruit weight increased by 11.94% and 15.93%, respectively, compared with no bacteria. Proline content increased with the application of bacterial, while the capsaicin content decreased.

Abstract

Combining the application of organic manure with inorganic fertilizer treatment can improve the productivity of the cucumber. Biogas slurry is synthesized from organic manure that can improve soil fertility and increase the yield of cucumber. This research aimed to learn the effect of biogas slurry and inorganic fertilizer on soil fertility and its impact on yield of cucumber and to learn the role of biogas slurry in decreasing amount of inorganic fertilizer used on the crop. This research was conducted in former paddy field located in Wriginsongo village, District of Tumpang, Malang Regency from March to May 2017. A randomized block design factorial was used with biogas slurry treatment as the main plot which consists of three levels: 10 t ha-1, 20 t ha-1, and 30 t ha-1while the subplot was the dosages of inorganic fertilizer which consists of100%,75%and 50% dosage of recommendation. This research revealed that biogas slurry treatment could increase the organic matter on the plant. There were some interactions between biogas slurry and inorganic fertilizer in the number of fruits produced, the weight of the fruit, the total weight of fruit produced per plant and hectare. Biogas slurry improved organic matter from 0.29% to 2.06%, N total from 0.06% to 0.15%, P2O5 from 93.48 ppm to 224.31 ppm, K2O from 2.01me 100 g-1 to 100 me 100 g-1, and C/N ratio from 3 to 9.

Abstract

Tomatoes are a horticultural commodity and the main priority to be developed in Indonesia. To improve the production of tomatoes, land expansion is needed. Managing marginal land to grow tomatoes can be an option. Marginal land such as saline land has the potential to be developed as an alternative. This research is aimed to investigate the effect of K fertilizer on the growth and yield of tomato plants at different levels of salinity. The experiment was conducted in a greenhouse located in the rural area of Bendosari in Kediri, East Java, using factorial randomized block design. The first factor was NaCl concentration (0, 3000, 6000 and 9000 ppm) while the second factor was the dosage of ZK fertilizer (75, 150 and 225 kg/ha). The results Showed that salinity level reduced growth and yield of tomato while the dosage of ZK fertilizer did not affect. Salinity level on 3000 ppm reduced leaf area 20.35 %, shoot dry weight 27.18%, root dry weight 28 %, number of fruit 24.14 %, fruit weight per fruit 29.82 % and fruit weight per plant 12.42 %. However, salinity level on 6000 and 9000 ppm ware not significantly different at all variables except 6000 ppm in leaf area (reduced 37.06%) and 9000 ppm on the number of fruit (reduced 43.01%).

Abstract

Salinity is a common problem of abiotic stress in the world. Salinity stress causes yield loss in cultivated crops, such as maize. The yield of maize exposed to salinity stress can be increased with the application of some beneficial microorganisms. Three isolates of halotolerant bacteria from saline fields can potentially be used as biostimulants (plant growth-promoting rhizobacteria). A field experiment to study the effect of halotolerant bacteria isolates application on the growth and yield of maize (Zea mays L.) in saline soil was arranged in a randomized block design with a combination of isolate types and frequency applications, and it was repeated three times. In this study, four bacterial strains used were SN13 (Streptomyces sp.), SN22 (Bacillus megaterium), SN23 (Bacillus sp.) and SN26 (Bacillus aryabhattai) isolated from the soil of saline-prone regions of Lamongan, in coastal East Java, Indonesia. Results indicated that an application of halotolerant bacteria was able to improve the yield and nutrient uptake of maize in saline soil. However, the application of halotolerant bacteria significantly improved leaf total chlorophyll content (105.94%), plant dry weight (56.14%), Grain weight per cob (108.11%) and had a positive trend in increasing N uptake (61.19%), and Na uptake (73.09%) compared to control. It is concluded that the application of halotolerant bacteria is able to alleviate the salinity stress of maize in saline soil.

Abstract

Cutleaf groundcherry (Physalis angulata L.) has the potential to be developed in various areas, including dryland. Information on drought-tolerant varieties, lines, or genotypes is needed for the development of cutleaf groundcherry in dryland. Selecting drought-tolerant lines is an alternative for alleviating yield loss potency caused by water shortages. A pot experiment that aimed to investigate the response of cutleaf groundcherry lines to a different level of water deficit, expressed in field capacity (FC), was run in two factors of factorial randomized block design. Each line (PA-01, PA-03, PA-05, PA-08) was set up in water deficit treatment (100, 80, 60, 40, and 20% FC). The result showed that vegetative growth and fruit production, such as fruit number and weight, mainly decreased at 60 or 40 % FC. In contrast, TSS increased at a higher water deficit which was in line with total flavonoid content, even inconsistently. PA-03 and PA-08 experienced a reduction in fruit weight at 40% FC, whereas other lines occurred at 60% FC. Water use efficiency (WUE) increased under severe water stress. Compared to other lines, PA-03 and PA-08 exhibit higher WUE at 60% FC. In conclusion, PA-03 and PA-08 lines were tolerant of water deficit.
