Tailings are waste generated from the processing of gold ore. The tailings in Kertajaya Village, Sukabumi are generally dumped into a pond or garden which is then used by the community to grow crops. The characteristics of the tailings, which contain low organic matter, microorganism activity, CEC and essential nutrients, make it necessary to improve their condition. This study aimed to determine the effect of adding top soil and compost to the tailings on the growth of sweet potatoes in the vegetative phase. This experiment used a factorial randomized block design with two factors, namely a top soil-tailing ratio of 3 levels (70: 30% w/w; 50: 50% w/w; and 30: 70% w/w) and a compost dose of 4. level (without compost (control); 10 t ha-1; 20 t ha-1; and 30 t ha-1) with 3 replications. The results showed that the combination of the addition of top soil ratios and the dose of compost to the tailings had no effect on the addition of tendrils length, tendril diameter and number of sweet potato branches during the vegetative phase. The addition of 70% top soil independently on the tailings had an effect on the highest increase in tendril length, tendril diameter and number of branches of sweet potato. Meanwhile, the application of compost dosage of 30 t ha-1 had the highest effect on the number of branches of sweet potato.

The use of inorganic fertilizers has an important role in increasing plant growth and production. But it also causes various problems such as decreasing soil organic matter, soil acidity, soil degradation, nutrient imbalance and increasing environmental pollution. Therefore, it needs to be balanced with the provision of organic fertilizers. A field experiment was conducted to study the effect of application of various doses of inorganic and organic fertilizers on N, P, K nutrient uptake and maize plant growth. The experimental design used was a randomized block design arranged in a factorial manner consisting of two factors. The first factor is the dose of inorganic fertilizer (A): 0, 150 and 300 kg ha-1 phonska and the second factor is organic fertilizer plus (P): 0, 10, 20 tons ha-1. The two factors were combined and each treatment combination was repeated three times. The data obtained were analyzed by analysis of variance at the 5% level of significance. The results showed that there was no interaction between the application of inorganic and organic fertilizers on the growth and nutrient uptake of N, P and K. However, the application of inorganic and organic fertilizers had a significant effect on all tested agronomic traits except for plant height. Nutrient uptake of N, P and K also increased significantly due to the application of inorganic and organic fertilizers. The balance of inorganic and organic fertilizer application increases the availability of nutrients as well as the uptake of N, P, and K nutrients by maize plants.

The use of Efficient Microorganisms (EM) can be an effective alternative to improve plant growth and yield in the bean cultivation. Therefore, different forms of application of efficient microorganisms were evaluated in the production of two cultivars of the common bean from November of 2013 to March of 2014. Two factors were studied; the first one was comprised of the two cultivars, Velazco Largo (VL) and Cuba Cueto (CC-25-9-N). The second factor consisted of four treatments with EM; without EM (control), soil inoculation (100 mL L-1), foliage applications (100 mL L-1), and the combined soil inoculation (100 mL L-1) plus foliar applications (100 mL L-1). The experiment was carried out in a randomized block design, in factorial outline 2×4, with three repetitions. The agronomic indicators were evaluated as the number of leaves per plant, the height of plants, number of pods per plant, number of seeds per pod, the mass of 100 seeds (g) and the yield (t ha-1). The results showed that the different forms of application of efficient microorganisms stimulated the agronomic indicators evaluated in both crops. The associated applications between the inoculation of the soil and foliage applications of efficient microorganisms provided better results, producing increments in the yield of 1.13 t ha-1 in VL and 2.15 t ha-1 in CC-25-9-N.

Livingstone potato (Plectranthus esculentus N.E.Br) is an underutilised indigenous root vegetable grown by communal farmers in the eastern provinces of Zimbabwe. It is vegetatively propagated using unimproved retained tubers from the previous season. The risk of disease carryover is therefore high, leading to poor yields. The objective of the study was to exploit the tissue culture technique of micropropagation to produce a mass supply of healthy planting material for improved productivity. Two experiments were conducted: firstly, to determine the best explant type and secondly, to determine the best landrace and plant growth regulators for the growth of plantlets. The landraces, namely, Ndurwe, Musande, Chibanda, and Chizambezi, were sourced from communal farmers in the stated production areas. Naphthalene acetic acid (NAA) and benzyl amino purine (BAP) were the auxin and cytokinin used, respectively. The first experiment was laid out as a randomized complete block design (RCBD) with two factors: landrace and explant type (shoot tips, nodes, and leaves). After culturing the explants on a plain Murashige Skoog (MS) medium for ten weeks, the best explant was the node with regards to the number of nodes, shoots, and roots of the plantlets which were significant (P<0.05). The second experiment was laid out as a RCBD with two factors: landraces and the plant growth regulator combinations. The nodes were subcultured on an MS medium supplemented with the 16 combinations of plant growth regulators (0 mg/l, 0.5 mg/l, 1 mg/l, and 2 mg/l BAP concentrations: 0 mg/l, 0.2 mg/l, 0.5 mg/l, and 1 mg/l NAA concentrations), respectively. Chizambezi performed best and is, therefore, highly recommended for the rapid multiplication of Livingstone potato. Results from this study have clearly demonstrated that the addition of NAA: BAP at varying concentrations was significant and is essential for optimizing the growth media for micropropagation of Livingstone potato in Zimbabwe. Commercial production of plantlets can, therefore, be carried out to provide healthy planting material for the communal farmers for improved productivity while preserving the germplasm of the underutilised crop at the same time.
