Abstract Shallot production in Indonesia is still relatively low. This is due to the use of shallot bulbs that are not sterile and susceptible to disease. One way to increase the production of shallots is by using botanical seeds (True Shallot Seed). The research aimed to evaluate the growth and yield of two varieties of TSS with the application of NPK and Magnesium fertilizers. The treatment was arranged in a randomized block design with three factors. The first factor was varieties, which consisted of Sanren F1 and Lokananta varieties. The second factor was the application of magnesium, which consisted of without magnesium, 125, and 250 kg Mg ha−1. The third factor was the application of NPK, which consisted without NPK, 83.3, 166.6, and 250 kg NPK ha−1. The results showed that the effect of varieties, NPK fertilizer, and Mg were significant differences in the parameters of the number of leaves 7.0, and the number of bulbs plants 2.7 where sanren showed better results. While the effect of varieties, NPK, and Mg fertilizers was significant differences in the parameters of plant height 41.5 cm, the Lokananta varieties showed better yields.

Aims: To assess the field establishment of two tea cultivars under Cocoa Pod Husk (CPH) and Poultry Manure (PM). Study Design: Randomized complete block design arranged in Split-plots (cultivars as main plots and organic amendments as sub-plots) with four replications. Place and Duration of Study: Cocoa Research Institute of Nigeria stations in Ibadan and Owena, Southwest Nigeria between May 2016 and November 2017 (Rainy and dry seasons of 2016; Rainy season of 2017).  Methodology: Milled CPH and cured PM were applied each at the rates of 150 and 300 kg Nha-1 to established C143 and C318 tea cultivars on the field; unfertilized tea cultivars served as control. Data on number of leaves, number of branches, leaf area, plant height and stem diameter were collected on monthly basis; while dry matter was assessed at 15 months after transplanting. The data were analyzed with ANOVA and correlation at α.05. Results: The C143 performed better than C318 and 150 kg Nha-1 of CPH and PM enhanced the vegetative growth and dry matter of tea better than 300 kg Nha-1 in Ibadan and Owena. Cultivar 143 was significantly (P=0.05) better than cultivar 318 in number of leaves, number of branches and stem diameter in Ibadan; and in number of leaves and leaf area in Owena. CPH at 150 kg Nha-1 increased number of leaves, number of branches, leaf area, plant height and total dry matter by 135.11, 88.19, 346.12, 65.33 and 428.11% at Ibadan; and by 349.09, 245.41, 376.89, 80.89 and 231.49% at Owena, compared to control. On the interaction, tea cultivar 143 that received 150 kg Nha-1 CPH produced significantly (P=0.05) higher number of leaves, leaf area and total dry matter at Ibadan and Owena. Leaf area was positively correlated with number of leaves (r=0.87) in Ibadan and stem diameter (r=0.80) in Owena. Conclusion: CPH at 150 kg Nha-1 enhanced the growth and dry matter content of C143 tea established on the field in Ibadan and Owena, and is therefore recommended for tea cultivation in Southwest of Nigeria.

Cassava is one of the local food sources that are widely available in almost every region. Cuttings are used to plant cassava, and these cuttings will produce a number of roots and buds. The main purpose of this study was to evaluate the effect of cuttings slices model and the number of buds on the growth of Tobelo local varieties of cassava. This study employed a factorial Randomized Block Design (RBD), with the cuttings slices model as the first factor, consisting of three levels, namely: flat slice, one-sided slice and two-sided slice. The second factor is the number of buds, which is divided into three levels, 1 bud, 2 buds and 3 buds. The observation parameters in this study include plant height, number of leaves, stem diameter and leaf area. The results have revealed that the model of two-sided sliced cuttings combined with the number of one bud is the most effective treatment in improving the growth of cassava plants of Tobelo local varieties. The models of one-sided and two-sided oblique cuttings slices yield the highest average value for the parameters of plant height, stem diameter and leaf area, while the treatment with one bud tends to give the best results for the growth parameters.

Shallots (Allium ascalonicum L.) is one of the leading vegetable commodities used as food seasoning and traditional medicine. This study aims to see the effect of providing various doses of NPK fertilizer and types of biological fertilizers on the growth and production of shallot plants. This study used a randomized block design (RAK) arranged in a factorial (4 x 2). The first factor is the NPK fertilizer dosage which consists of four levels, namely: N0= 0% (without NPK fertilizer), N1= 50% (25 g/m2), N2= 100% (50 g/m2), and N3= 150% (75 g/m2). The second factor is the type of biological fertilizer which consists of two levels, namely: H1= Grikulan plus fertilizer and H2= EM4. The results showed that the NPK fertilizer dosage treatment up to a dose of 75g/m2 gave the best results on plant growth and development, including the number of leaves, plant height, fresh tuber weight per plant, wind dry tuber weight per plant, and wind dry tuber weight per m2. The growth and development of shallot plants with the application of Grikulan biological fertilizers were better than those of EM4 biological fertilizers. Treatment of NPK fertilizer dosage of 150% or equivalent to 75 g / m2 supplemented with the application of Grikulan plus fertilizer results in higher production, namely the weight of dry tubers per m2 reaching 1674.33 g or equivalent to 11.72 tonnes/ha. Keywords : EM4, Grikulan plus, shallots,NPK, yield
