The paitan plant contains allelopathic compounds for other plants so that the utilize of paitan plant as a source of liquid organic fertilizer (LOF) has not been widely applied. This research aimed to study the interaction between LOF dosage and appropriate application method of LOF to increase the growth of kailan plants. The research conducted at experimental garden of UIN Bandung from June-August 2016. The experimental design was a completely randomized design with two factors and replicated four times. The first factor was application methods (A), i.e. a1=direct application to the soil, and a2= spraying. The second factor was LOF dosage (T), i.e. t0: 0 ml plant-1, t1: 20 ml plant-1, t2: 40 ml plant-1, t3: 60 ml plant-1, t4: 80 ml plant-1. The growth parameters observed i.e. plant height (14, 21, 28, 35 and 42 Day after Transplanting (DAT)), leaf area 42 DAT, plant dry weight 42 DAT, and plant fresh weight 42 DAT. The data then analyzed with analysis of variance at a significant level of 5%. If the analysis of variance was significant, the Duncan multiple range test was used at α=5%. The research results showed there was no interaction between method of application with a various dosage of paitan LOF to all of the growth parameters. The application paitan LOF showed similar growth in terms of plant height, leaf area, plant dry, and plant fresh weight. The application method of paitan LOF direct to the soil or spraying to leaves can not increase kailan plant growth.

                    The presence of weeds in crop cultivation has a negative effect on the crop because of their high competitiveness. One of the roles of weeds as allelopathy because weeds release chemical compounds that can inhibit growth and kill plants around them. This study aimed to determine the effect of concentration of ‘bandotan’ plant extracts plants at various application times on the growth and yield of mustard. The research was carried out at the Greenhouse of the Faculty of Agriculture, Pattimura University, from November 2017 to January 2018. This study used an experimental method with a completely randomized design (CRD) involving two factors and with three replications. The first factor was ‘bandotan’ extract with 4 concentration levels: control (no extract), 100 g/L, 200 g/L and 300 g/L. The second factor was application time with three levels: 5 days after planting (DAP), 10 DAP, and 15 DAP. The variables observed included plant height, leaf number, leaf area, fresh crop weight, and crop dry weight. Data analysis of each variable was conducted using the analysis of variance. If there was a significant treatment effect, it proceeded with the Tukey test at the level of α = 0.05. The results showed that the concentration of ‘bandotan’ extract did not significantly affect all observation variables (plant height, leaf number, leaf area, fresh crop weight, and dry weight of mustard). Time of ‘bandotan’ extract application did not significantly affect all observation variables (plant height, leaf number, leaf area, fresh crop weight, and dry weight of mustard). The interaction between ‘bandotan’ extract concentration and application time did not significantly affect all observed variables. Keywords:  application time, ‘bandotan’ extract, green mustard, growth and yield   ABSTRAK Keberadaaan gulma pada tanaman budidaya berpengaruh negatif pada tanaman itu karena daya kompetitif yang tinggi.

Results of a pot experiment carried out on spinach with vermicompost (5, 10 and 15 ton/ha), phospho-rous (10, 20 and 30 kg/ha) and potassium (20, 30 and 40 kg/ha) fertilizers showed that plant height, leaf area, fresh and dry weight of plants increased significantly (p ≤ 0.5) over the control. Highest height (23.55 cm), leaf area (80.88 cm2/plant), fresh weight (3.838 g/plant) and dry weight (0.274 g/plant) were maximum in VC15P20K30, VC15P30K30, VC10P20K30 and VC10P10K40, respectively, while leaf number was almost same in all the plants. Highest protein content (24.61%) was obtained in the treatment VC15P10K20. Highest dry matter of leaf was obtained at VC10P10K40, but the highest protein content was at VC15P10K20 which might be due to dilution effect. Similar values of protein content were obtained in treatments VC5P20K30, VC5P20K40, VC5P30K20, VC15P10K40, VC15P20K30 and VC15P30K20. Maximum value of nitrogen, phosphorous (1.621%) and potassium (4.066%) were obtained in treatments VC5P20K20 and VC10 P30 K40, VC15 P10 K20, respectively.

SUMMARYAn experiment has been carried out in order to study the behaviour under mineral deficiency of three sunflower genotypes, a population variety (Oro 9) and two hybrids (Mirasol and Albena). Sunflower seedlings were submitted to five treatments: N deficiency (N0), P deficiency (P0), K deficiency (K0), N and K deficiency (N0K0) and a control. Plants were harvested when they reached 3-4 true pairs of leaves. Growth parameters measured (height, total leaf area, root length, root and shoot dry mater) were all significantly reduced by mineral deficiency. Leaf area was most reduced by N0 (-61%) and P0 (-56%). Total dry matter was most affected by N0 (-63%) and by N0K0 (-66%). Genotype comparisons showed that Oro 9 had the highest shoot dry matter while Albena had the lowest root dry matter. Effect of mineral deficiency on content and partitioning of N, P, K, Ca and Na was significant and varied according to treatments and among plant parts. Shoot dry weight was significantly correlated with root N content (r2=0.81) and root K content (r2=-0.61) for N0 and K0.

The investigation was carried out to evaluate the effect of different organic manures on turmeric with reference to vegetative growth, biomass production, rhizome yield and its attributes of turmeric (Curcuma longa L.). Turmeric showed better response to the application of organic manures. Plant with neem cake application had the taller plant (79.30 cm), maximum number of tillers per plant (5.40), leaf number (5.40), leaf area (44.09) leaf area index (0.429), fresh weight of halum ( 190.05g), fresh weight of root (49.13 g), fresh weight of rhizome per plant (256.21 g) and dry weight of halum (15.21g), dry weight of root (7.32 g), dry weight of rhizome per plant (40.35 g), total dry matter yield (6.85 t ha-1) than those received other types of manures. Moreover, yield attributes such as number of mother rhizomes per plant-1 (1.75), more number of primary rhizomes per plant-1 (5.19), secondary rhizomes per plant-1 (18.03) and tertiary rhizomes per plant (7.69) were also highly accelerated by neem cake application. Similarly, the same treatment expressed the best in terms of size of mother rhizome (7.69 cm), primary rhizome (21.86 cm) and secondary rhizomes (7.05 cm).All these parameters in cumulative contributed to  produce the highest estimated fresh rhizomes yield & cured rhizomes yield (29.48 t ha-1, 5.59 t ha-1 respectively). The highest curing percentage (20.28) was observed in T3 treatment having mustard cake@ 2.0 t/ha. Thus, organic manure like neem cake was best fitted natural fertilizer for turmeric cultivation.DOI: http://dx.doi.org/10.3329/agric.v10i1.11060The Agriculturists 2012; 10(1): 16-22
