Soybeans are a very important food requirement in Indonesia, but they often face drought problems. Drought stress causes inefficient nitrogen absorption and makes the stomata close early so photosynthesis is not optimal, resulting in reduced yield. This research was conducted from August 2020 to October 2020 in Demangan village, Sambi sub-district, Boyolali district with polybags in a plastic house. This research method used Factorial Completely Randomized Design (CRD) consisting of two factors and repeated 3 times. The first factor was soil moisture content consisting ie. 100%, 75%, 50%, and 25% of field capacity. The second factor, the growth phase consists of active vegetative, flowering, and seed filling. Observations included the number of branches, number of productive branches, number of trifoliate leaves, the weight of filled pods, and weight of 100 dry seeds. Drought stress reduced the growth and yield of soybean at 25% moisture content in the field capacity of the seed filling phase. The number of branches, the number of productive branches, the number of trifoliate leaves, the weight of filled pods, and the weight of 100 dry seeds decreased with the lowest value.

<p>Soybean demand in the market today has not been matched by domestic production. Many of the problems that cause insufficient  production of soy,  one of which is  the drought  affecting soybean growth and  yield. Efforts should be made to overcome the drought is to provide soybean varieties tolerant to drought stress. This study aims  to  assess  the  effect  of  the  difference  in  intensity  of  drought  stress  on the growth of some soybean varieties. This study uses a completely randomized design (CRD) factorial with two factors, the first factor and the second factor soybean varieties  drought  stress  levels.  Results showed significant  of lowering the value of RGR and NAR. The higher the level of drought stress will decrease soybean growth. Tolerance limits for each variety is at 80% moisture content.</p>

<p>ABSTRACT</p><p>Drought stress in crop occurs due to imbalance between demand and supply of water. Crop responses to drought stress depend on their genotypes. Drought stress causes anatomical changes and root damage. The objective of this research was to study the effect of drought stress on anatomy and physiology of soybean root. The research was conducted at Laboratory of Microtechnique, Department of Agronomy and Horticulture, Bogor Agricultural University in November 2013. A Completely Randomized Design with two factors was used in the research i.e. soybean genotypes (Wilis, PG 57-1, SC 39-1) and PEG (0, 20%) with three replications. The result showed that genotype and PEG affected the size of the cortex, stele, and xylem. PG 57-1 genotype showed the decrease of cortical thickness, diameter of stele and the diameter of xylem, on the other hand, in SC 39-1, there was an increase. Drought stress (PEG 20%) could also cause damage to the root membrane as indicated by the occurrence of lipid peroxides. Wilis and PG 57-1 were tolerant while SC 39-1 was sensitive to drought stress.</p><p>Keywords:cortex, lipid peroxides, PEG, Schiff’s reagent, xylem</p>

<p>Mungbean is one of the strategic annual food crops that needed by Indonesian people because of the high protein and minerals. Production of mungbean in Indonesia always decreases. Cultural improvements are needed to increase productivity i.e by appropriate fertilization and plant density. The experiment objective was to find out the optimum dosage of organic fertilizer and plant density for the growth and yield of mungbean. The experiment was carried out using factorial completely randomized design (CRD). The first factor treatments were organic fertilizer which consisted of 0, 5, 10, 15, and 20 ton ha<sup>-1</sup>, while the second-factor treatments were planted density which consisted of 1 and 2 plants in the hole. Organic fertilizer of 5 ton ha<sup>-1</sup> gave the best result for plant height, number of branches, flowering age, number of pods, fresh weight and dried straw, weight of 100 seeds, number and weight of seeds, small of seeds number and P nutrient uptake of the plant. The 2 plants per hole gave the best result for branches number, pods number and number of small seeds. Application of 5 ton ha<sup>-1</sup> organic fertilizer and 1 plant per hole gave better yield. No interaction of organic fertilizer and plant density to mungbean growth and yield.</p>

The objective of this research was to examine the effect of giving Rice MOL and superior plant hormone on growth and yield of Chilli.  The experiment was arranged using the completely randomized design with two factors. The first factor was rice MOL (M), namely M0 (without rice MOL), M1 (50 cc/l water), M2 (100 cc/l water), and M3 (150 cc/l water).The second factor was application of superior plant hormone (H), consisting of four factor, namely H0 (without hormone), H1(1 cc/l water), H2 (2 cc/l water), and H3 (3 cc/l water). The parameters observed were plant height, flowering age, the first harvest age, fruit weight per plant, fruit weight per plot, and number of remaining fruit. Data were analyzed using statistical technique and continuing test of BNJ at 5% confident level. The results showed that the interaction of giving rice MOL and hormone had a significant effect on flowering age and harvest age with the best treatment M2H2 with 56.67 days and M2H2 with 112.67 days, respectively.  The rice MOL alone gave a significant effect on flowering age, the first harvest age, econmic fruit weight per plant, and  economic fruit weight per plot with the best treatment was M2. The superior plant hormone alone affected significantly plant height, flowering age, the first harvested age, economic fruit weight per plant, economic fruit weight per plot, and number of remaining uneconomic fruit per plant with the best treatment of H2.

Drought stress is one of the most important environmental factors which can limit the lentil production. To evaluate the effect of drought stress at flowering and pod filling stages on growth indices of lentil cultivar Kimiya (a new high yielding lentil cultivar for moderate cold and semi warm climate of Iran), an experiment was conducted at the research greenhouse of Higher Educational Complex of Saravan in completely randomized design with four replications. The drought stress was applied by withholding irrigation until the soil moisture reached to 20% of field capacity at stages of flowering and pod filling. In this experiment, we measured grain yield per plant, growth indices including plant leaf area (PLA), relative growth rate (RGR), plant growth rate (PGR), and net assimilation rate (NAR). Results showed that the flowering stage in lentil plant is more sensitive to drought as exhibited significant decline in PLA, RGR, PGR and NAR. PGR declined at the end of growing season when vegetative growth stop, senescence of leaves, the reduction of NAR, and the allocation of assimilate to the seeds.
