Nitrification is the oxidation process of NH4+ to NO3- microbially. The nitrification process can produce compounds in the form of NO3-, N2O, or NO which can cause environmental pollution through water, soil, or air, thus harming living things. The research was conducted to find ways to inhibit or control nitrification effectively and sustainably. The experiment was carried out in a plastic greenhouse located in Plesungan, Karanganyar until the maximum vegetative planting period of corn around May-June using a completely randomized design three replications. Andisols soil media was taken from Tegalrejo Village, Tengaran District, Semarang Regency 07º25'28.3 '' LS and 110º31 '35.7 '' BT with an altitude of 760 meters above sea level. There are 5 treatments, one control, four are natural inhibitor treatments in the form of litter addition. The litter used was Gliricidia maculate, Albizzia falcataria, Senna siamea, and Tithonia diversifolia. Statistical analysis showed that treatment just significantly affect NO2- concentrations (potential nitrification), not significantly affect NH4+, NO3- concentrations, and efficiency utilization of N. However, measurement results in the laboratory and field showed that the addition of local litter could inhibit nitrification, which was demonstrated through the efficiency of N utilization. Tithonia diversifolia because it has the highest average N utilization efficiency of 25.79%, 58.71% more efficient than control treatments. Also followed by plant growth results showed that the root’s dry weight and canopy’s dry weight positively correlated with NH4+ concentrations and efficient utilization of N, also canopy’s dry weight negatively correlated with NO2- concentrations (potential nitrification). The highest results occurred in the Tithonia diversifolia treatment.

ABSTRACT In order to investigate salinity stress on seed reserve utilization and seedling growth of treated seeds of barley (Hordeum vulgare L.), an experiment was carried out. Factorial experiment was carried out in completely randomized design with three replicates. To create salinity stress, NaCl in osmotic levels at 0 (as control), -4, -8, -12 and -16 bar were used. For seed priming, gibberellin (GA) 50 ppm was used. Our results showed that treatment × drought interaction on these traits: germination percentage, weight of utilized (mobilized) seed, seed reserve utilization efficiency, seedling dry weight and seed reserve depletion percentage were significant. The highest germination percentage, weight of utilized (mobilized) seed, seed reserve utilization efficiency, seedling dry weight and seed reserve depletion percentage were attained from priming by gibberellin at control conditions. Thus, priming increased characteristics as compared to the unprimed. Priming improved seed reserve utilization such as: weight of utilized (mobilized) seed reserve, seed reserve depletion percentage, seed reserve utilization efficiency and seedling growth in barley under salinity stress.

The effect of atrazine (2-chloro-4-ethylamino-6-isopropylamino-.s-triazine) on growth of Sclerotium rolfsii and Trichoderma viride was studied in liquid culture. The fungi were grown in Czapek solution containing 0, 8, 20, 40, and 80 μg of the herbicide per milliliter, and growth responses were measured at intervals of 3–5 days after inoculation. Mycelial dry weight of S. rolfsii was little affected at concentrations below 40 μg/ml, but was decreased at the higher concentrations. Total mycelium produced by T. viride was greater with all atrazine treatments than in the control. For S. rolfsii, the efficiency of utilization (economic coefficient) of glucose, inorganic P, and NO3-N with atrazine at 8 μg/ml was slightly higher than that of the control, but was significantly reduced at higher concentrations. Values for glucose utilization efficiency in T. viride increased with herbicide at 8 and 20 μg/ml, then decreased considerably at other concentrations, but remained higher than the control; a similar pattern was revealed for P and NO3-N utilization. Titratable acidity in the medium increased for both fungi with increased atrazine concentration.

Purpose. Jute mallow (Corchorus olitorius L.) is a mucilaginous vegetable and fiber crop cultivated in the tropics, where catnip (Nepeta cataria L.) and Mexican sunflower (Tithonia diversifolia L.) are common weeds. Hence, the study investigated the growth, yield, and nutrient level of jute mallow in weed-free, catnip, and Mexican sunflower environments. Methods. The study involved two screen-house experiments in a Completely Randomized Design (CRD) with six replications. The treatments were 0 (control), 2, 4, 6, 8, and 10 weed plants per pot in both experiments. These are 0, 100, 200, 300, 400, and 500 weed count per square meter equivalent, based on the surface area of the pots used. Mexican sunflower and catnip plants interacted with jute plants in the first and second experiments, respectively. Growth parameters of jute mallow were recorded weekly from 5 to 8 weeks after sowing (WAS), and harvesting was done at 8 WAS. The proximate composition of jute was evaluated using standard procedures outlined by AOAC. The data collected were subjected to analysis of variance (ANOVA), and means were separated using Duncan Multiple Range Test (DMRT) at P < 0.05. Results. Catnip and Mexican sunflower negatively impacted the morphological features of jute mallow from 100 plants per square meter upwards. Catnip and Mexican sunflower, at 300 and 100–500 plants per square meter, respectively, reduced the dry weight of jute mallow. The crude protein content of jute mallow was also lessened by Mexican sunflower at some point. Conclusions. The study recommends that the density of catnip and Mexican sunflower plants interacting with jute mallow should be maintained below 100 plants per square meter to prevent yield loss.
