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.

A pot experiment was carried out at the Agronomy Teaching and Research Farm of the University of Agriculture Makurdi to determine the effect of manganese fertilizer on the growth and yield of rice. Treatment consists of five levels of Manganese (Mn) (0, 5, 10, 15 and 20 kg ha-1) in form of MnSO4. The treatments were laid out in a Completely Randomized Design (CRD) with three replications. The effect of Mn on the growth of rice indicate that there were no significant difference in the growth parameters measured with the exception of plant height at 8 weeks after planting and number of tillers at 4 weeks after planting. The tallest plants and highest number of tillers were obtained with 10 kg ha-1 Mn. The effect of Mn on the yield of rice indicate that there was a significant difference in the yield parameters measured with the exception of number of grain per panicle and root weight at 4 weeks after planting. Manganese at the rate of 10 kg ha-1 gave the highest grain yield (2,667 kg ha-1) and highest dry matter weight. Levels of Mn above 10 kg ha-1 led to yield decrease, therefore application of 10 kg ha-1 Mn was recommended for optimum yield of rice.

A pot experiment was carried out to assess the comparative effects of Trichoderma-enriched biofertilizer and farmyard manure on the growth and yield components of brinjal (Solanum melongena L.). The treatments were T0 (control), T1 (Trichoderma-enriched biofertilizer 5 t/ha), T2 (Trichoderma-enriched biofertilizer 10 t/ha), T3 (Trichoderma- enriched biofertilizer 15 t/ha), T4 (Farmyard manure 5 t/ha), T5 (Farmyard manure 10 t/ha) and T6 (Farmyard manure 15 t/ha). The experiments were laid out in completely randomized design (CRD) with three replications of each treatment. Among the different treatments T3 showed best as much as twice more effective than farmyard manure in increasing growth and yield parameters (plant height, fruit length, fresh weight and dry weight of stem, leaf and fruit) of brinjal plants. Overall, all the treatments increased macronutrients and micronutrients content and uptake by brinjal plants over control. Analysis of post-harvest soil samples also revealed that all the parameters except pH were increased due to different treatments. Dhaka Univ. J. Biol. Sci. 29(1): 1-8, 2020 (January)

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>
