Aims: The purpose of this study was to obtain the best interaction between guano doses and mulch on the growth and yield of potato plants. Study Design: The experimental design used was factorial 2 factors in a completely randomized design (CRD). Place and Duration of Study: This experiment was carried out in Alahan Panjang, Lembah Gumanti District, Solok Regency, West Sumatra from March to June 2018. Methodology: Factorial design 2 factors was use in research. The first factor consisted of 4 levels of guano fertilizer doses of 0, 3, 6 and 9 t ha-1. The second factor consisted of black silver plastic mulch and black plastic mulch. Data were analyzed statistically with the Fisher test and if significantly different then continued with the Duncan’s New Multiple Range test (p≤0.05) Results: No interaction between guano fertilizer and the two types of mulch tested with respect to plant height, number of leaves, and smallest tuber diameter were observed. Guano fertilizer at 9 t ha-1 gave the best influence on the number of tubers and the diameter of tuber. Black plastic mulch had the best influence on the number of tubers, the diameter of tuber, the weight of tubers per plant and the weight of tubers per hectare. Conclusion: The dosage of guano fertilizer of 9 t ha-1gave the best effect on the number and diameter of tubers. The type of black plastic mulch gave the best effect on tuber number, tuber diameter, tuber weight per plant and tuber weight per hectare.

Salinity stress is a severe environmental stress that affects plant growth and productivity of potato, a strategic crop moderately sensitive to saline soils. Limited studies are available on the use of combined nano-micronutrients to ameliorate salinity stress in potato plants (Solanum tuberosum L.). Two open field experiments were conducted in salt-affected sandy soil to investigate plant growth, physiology, and yield of potato in response to soil salinity stress under single or combined application of Zn, B, Si, and Zeolite nanoparticles. It was hypothesized that soil application of nanoparticles enhanced plant growth and yield by alleviating the adverse impact of soil salinity. In general, all the nano-treatments applications significantly increased plant height, shoot dry weight, number of stems per plant, leaf relative water content, leaf photosynthetic rate, leaf stomatal conductance, chlorophyll content, and tuber yield, as compared to the untreated control. Furthermore, soil application of these treatments increased the concentration of nutrients (N, P, K, Ca, Zn, and B) in plant tissues, leaf proline, and leaf gibberellic acid hormone (GA3) in addition to contents of protein, carbohydrates, and antioxidant enzymes (polyphenol oxidase (PPO) and peroxidase (POD) in tubers. Compared to other treatments, the combined application of nanoparticles showed the highest plant growth, physiological parameters, endogenous elements (N, P, K, Ca, Zn, and B) and the lowest concentration of leaf abscisic acid (ABA) and transpiration rate. The present findings suggest that soil addition of the aforementioned nanoparticles can be a promising approach to improving crop productivity in salt-affected soils.

In a repeated multi-year study, mother potato plants were exposed to herbicides at rates that simulated off-target application, such as through tank contamination. Following exposure of mother plants to herbicides, seed from mother plants was planted in the following growing season and crop growth, yield and tuber quality were quantified. Visual injury from herbicides was observed both in the mother plant and daughter tuber growing seasons and occasional impacts on tuber yield were noted. However, an inconsistent relationship was observed for herbicide related injury and tuber yield reductions of mother potato plants with daughter tuber growth and yield. The lack of consistency in the relationship between visual potato injury in the mother plant production and adverse daughter tuber growth and yield in the following year challenges traditional crop scouting as a tool to predict off-target herbicide risk near seed potato production.

Potatoes (Solanum tuberesum, L) are one of the main foods for the needs of the world community. Therefore, increasing potato crop production is considered important. For this purpose, the utilization of a mixture of rice husk biochar with compost can provide the best results up to three times the planting season. Coffee skin can also be found in form of compost for the utilization process. However, due to the lack of farmer’s knowledge about the benefits that can be provided by skin compost to maintain the level of soil fertility. This study aims to analys the effect of biochar and coffee skin compost on the growth and yield of potato crops. Plant height, number of shoots, number of tubers per clump, and per plot tuber weight was a parameter of observation. This experiment used a factorial randomized planting block design using several doses of biochar and coffee skin compost.  The treatment of biochar dosage did not significantly affect all parameters observed. The treatment of the effect of doses of coffee skin compost had a very significant effect on plant height at all ages of observation. The average plant height increases with the higher doses of red coffee skin compost given has a very significant effect on the number of tubers per clump and the weight of per plot tubers. There was no real interaction between the biochar dose and the red coffee skin compost dosage against all observed parameters.

Research on the growth and formation of potato tubers was conducted to determine the effect of rhizobacteria isolates and coumarin applications growth inhibitors. Bacteria are isolated from the roots of potato plants that grow in the healthy roots of potato plants.The study used a two-factor complete randomized design with three replications. The first factor was rhizobacterial isolates BT.4.1 isolates, BT.4.2 isolates, BT.4.3 isolates. The second factor was the concentration of coumarin 0, 50, 100 and 150 mg L-1. Thus from the results of this study obtained of rhizobacteria BT.4.1, BT.4.3 and coumarin 100 - 150 mg L-1 increases the growth and yield of potato crops. Based on the results of potato tuber produced, the combination of BT.4.1 rhizobacteria, and coumarin 150 mg L-1 can increase growth and yield.
