AbstractDrought stress is one of the most important environmental factors in reduction of growth, development and production of plants. Germination of each seed is considered as one of the first and most fundamental life stages of a plant so that, the success in growth and yield production is also depending on this stage. To study the effect of PEG stress on germination and early seedling stages on maize, an experiment were laid out at laboratory conditions of Division of Genetics and Plant Breeding SKUAST-K FoA/RRS Wadura. This investigation was performed as factorial experiment under Complete Randomized Design (CRD) with three replications. Polyethylene glycol stress induced in laboratory caused progressive decline in both the parameters across all genotypes with increase in Polyethylene glycol from 0-20% and both the parameters (length of radical and root biomass) had highest value under control.

The objective of the experiment was to determine effects of Brassinosteroid (BRs) concentrations on growth, development and yield of Jasmine 85 rice cultivar under salinity conditions at panicle initiation stage. The experiment was laid out in a completely randomized design with three replications and consisted of two factors. The first factor comprised three salinity concentrations: 0‰ (control), 2‰ and 4‰ and the second factor had three concentrations of BRs: 0 ppm (control), 2 ppm and 4 ppm. The results showed that under non-saline conditions, the control rice plants sprayed with BRs at a concentration of 2 ppm had the highest values of root length (33.39 cm), leaf area (42.41 cm2), proportion of firm seeds (72.20%), weight of 1000 seeds (28.14 g) and yield (725.55 g/barrel). At the salinity level of 4‰, rice plants sprayed with BRs at a concentration of 2 ppm demonstrated the highest levels of APX and CAT enzymes. Briefly, rice plants grown under higher salinity levels had decreased growth and yield. Spraying BRs helped improve growth and yield parameters of rice under high salinity conditions.

Abstract: The objective of this work was to evaluate the growth and yield of teak (Tectona grandis) stands at different spacing and in different soil classes. Twelve spacing were evaluated in an Inceptisol and Oxisol, in plots with an area of 1,505 or 1,548 m2, arranged in a completely randomized design with nine replicates. The teak trees were measured at 26, 42, 50, and 78 months of age. Total tree height was less affected by spacing. Mean square diameter was greater in wider spacing, whereas basal area and total volume with bark were greater in closer spacing. An increase in volume with bark per tree was observed with the increase of useful area per plant. For teak trees, growth stagnation happens earlier, the growth rate is higher in closer spacing, and the plants grow more in the Inceptisol than in the Oxisol.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.

This research aims to determine the effect of plasticizer types and concentrations on the characteristics of glucomannan bioplastics, and to determine the types and concentrations of plasticizers that can produce glucomannan bioplastics with the best characteristics. This experimental design used a completely randomized design method. Factor I is a type of plasticizer consisting of glycerol, sorbitol, propanol-2, and polyethylene glycol. The second factor is the concentration of plasticizers which consists of 4 levels, namely 0.5%: 1.5%: 2.5%: 3.5%. The experiment resulted in 16 treatment combinations and grouped into 2 groups to obtain 32 experimental units. The data were analyzed for their diversity and continued with the Duncan multiple comparison test. The results showed that the type and concentration of plasticizers had a very significant effect on tensile strength, elongation at break, modulus young, and swelling. The interaction has a very significant effect on tensile strength and expansion and has a significant effect on the elasticity of glucomannan bioplastics. Meanwhile, the type and concentration of plasticizers had no significant effect on the length of biodegradation. The best glucomannan bioplastic was obtained in the treatment of glycerol plasticizers with a concentration of 1.5 % with a tensile strength value of 6.17 MPa, elongation at break of 21.50 %, elasticity 28.72 MPa development 25.84 %, and degradation time of 8 days. Bioplastics produced in this study have meet the SNI 7188.7:2016 standards in the elongation test at break and standards ASTM 5336 in the degradation time variables. The resulting bioplastic has not met SNI on the tensile strength, modulus young, and swelling variables. Keywords : bioplastic, glucomannan, glycerol, polyethylene glycol, propanol-2, sorbitol
