Aloe vera (Aloe barbadensis) is an important plant to cosmetics, pharmaceuticals, and food industry worldwide. In Colombia its cultivation has grown even when technical crop management is unknown. This study evaluated the growth of three aloe basal shoots weights ranges in two companion planting systems and monoculture (control). A completely randomized split plot design was used. Main plots were: aloe monoculture (AMN), common bean companion planting (CBCP), and giant taro companion planting (GTCP). Treatments were weight ranges from 50 to 150 g (LWe), 151 to 250 g (MW), and 251 to 350 g (HW). Data were analyzed using ANOVA, Duncan multiple range test (P≤0.05), and linear regressions. Variables evaluated were total height (TH), number of leaves (NOL), length (LL), width (LW), and leaf thickness (LT). In CBCP, GTCP, and MW variable LL predicted GH. Models fitted to HW and AMN were not representative (R 2 <0.64). CBCP obtained the highest values in NOL (17.8), TH (56.2 cm), LL (40.2 cm), and LW (5.8 cm). LWe and MW basal shoots reached non-significant differences one year after planting in any variable (P>0.05). Companion planting promotes predictability of aloe growth and CBCP associated with HW are a promising alternative to aloe cultivation.

A field experiment was conducted at National Citrus Research Program (NCRP), Paripatle, Dhankuta to standardize the time and method of grafting and to assess the success and growth of mandarin saplings. Scions taken from ‘Khoku Local’ mandarin were grafted onto one-year-old trifoliate orange seedling rootstocks by shoot tip and veneer methods in eight different dates starting from 29th October, 2009 to 12th February, 2010 at 15 days interval. The grafts were planted inside closed tunnel of jute and plastic sheet at 10×10 cm spacing in 50×60 cm2 experimental plots in two factorial split-plot design with three replications per treatment, containing 30 grafts per plot. The grafting methods were allotted on main-plots and the dates on sub-plots randomly. The success and growth of sapling was significantly affected by the dates while the methods had no effect. Study results showed that the highest success (96.11 %) was found on 13th January, followed by 28th January (91.11%) and the least (51.67%) on 29th October grafting. The mortality of sprouted grafts was the lowest (0.17%) in 29th December grafting, while it was observed higher in earlier and late season grafting. Observation on growth taken at 180 days after grafting in successful grafts showed that 29th October had the highest number of primary branches (2.2); 14th November had the highest number of leaves (48.47) and secondary branches (2.505); 29th December gave the maximum sapling height (32.86 cm); 13th January produced the lowest number of leaves (21.93) per sapling and 28th January produced the lowest number of primary (1.533) and secondary branches (1.172) per sapling. From the study it was revealed that in Dhankuta, the most appropriate time of grafting was 2nd to 4th week of January.

Long bean production in Indonesia continues to decline every year, this is due to land conversion and the lack of application of agricultural technology. One of the efforts to increase long bean production is by multiplying quality seeds using organic materials as nutrients needed by plants. This study aims to determine the response of the growth and production of long bean seeds to the interaction of strains, varieties with a concentration of liquid organic fertilizer. The research was conducted at the Vegetable Crops Research Institute, Lembang, West Bandung Regency from July 2020 to January 2021. The research method used was an experimental method with a Randomized Block Design (RBD) with a split-plot design consisting of 2 factors: the first factor (main plot) (A) was the variety and strain with 2 levels, a1 (Tavi canton variety) and a2 (pras-1 strain).The second factor (subplot) (B) is concentration of biopras-1 with 5 levels, b1 (0 cc/l-1 water), b2 (1 cc/l-1 water), b3 (2 cc/l-1 water), b4 (3 cc/l-1 water) and b5 (4 cc/l-1 water). The effect of the treatment was analyzed by means of variance and if the f test at 5% level was significantly different, then to find out the best treatment was continued with the DMRT (Duncan Multiple Range Test) at the 5% level. The results showed that there was an interaction between varieties, lines with various concentrations of biopras-1 liquid organic fertilizer on dry seed weight per plant, dry seed weight per plot, and 1000 seeds weight. Treatment of pras-1 lines with the concentration of liquid organic fertilizer biopras-1 4 cc / l of water was able to give the best results on dry seed weight per plant (35.31 gr), dry seed weight per plot (1.298.20 gr or 2.16 Ton/ha-1) and the weight of 1000 seeds (153.10 gr).

Aloe barbadensis (Aloe vera) plants remain in production fields for several years, with their lower leaves harvested periodically. A long-term experiment was initiated in November 1993 to determine the effects of fertilization and severeness of harvest on leaf yield. Plants were grown in large pots with or without monthly applications of a 20N–8.6P–16.6K soluble fertilizer from March to October. Beginning in June 1994, the lower leaves were harvested quarterly to have 18, 15, or 12 leaves remaining. Fertilization doubled the number of leaves harvested and tripled the total yield over a 2-year period. The lower leaves on the nonfertilized plants, particularly on plants with 18 leaves remaining, sometimes became dry or partially dry at harvest. The initial quarterly yield and cumulated yield were higher in plants with 12 leaves remaining; however, this trend disappeared over time. The fertilized plants produced an average of 10 kg per plant, while the nonfertilized plants produced only 3.2 kg per plant annually. At several harvests, plants with 18 leaves remaining had higher % dry mass in the inner semi-translucent tissue than those having 12 leaves. Leaves of nonfertilized plants had high % dry mass in the inner leaf tissue when harvested in June and September 1995. Plants with 12 leaves remaining can become unstable and the tops break off in gusty wind.

Corn and soybean are food crops which are ranked on the second and third position as the main crops with the highest yield in Indonesia. Based on data of 2012, corn and soybean harvested areas amounted 3,956 ha and 597.65 ha with the productivity of 48.99 tons/ha and 843.15 tons/ha, these areas increased up to 4,388 ha (corn) and 589.42 ha (soybeans) which lead an increase in corn and soybean production by 52.85 tons/ha and 887.54 tons/ha. However, increasing crop productivity, especially for corn and soybeans, cannot continuously use land expansion because the land area of Indonesia that is suitable for agriculture is only 94.07 million ha from 188.20 million of total land area. Thus, the solution to overcome this issue is by arranging the plant spacing and providing proper nutrients. Plant spacing in intercropping systems can minimize competition between plants to provide a well-grown of both plants. This research aimed to determine the increase in productivity of corn and soybean plants using intercropping systems through a combination of plant spacing and a combination of NPK fertilizer dosages. This study used a factorial experimental method that planted crops on the land with 2 factors with split-plot design of 4 × 3 factorial and 3 replications. The first factor is the combination of plant spacing with 4 levels, they were plant spacing of corn; 50 cm × 40 cm (J1), 75 cm × 40 cm (J2), 100 cm × 40 cm (J3), 125 cm × 40 cm (J4) and plant spacing of soybean; 40 cm × 20 cm. The second factor is 3 levels of NPK fertilizer dosages combination, they were 0% NPK fertilizer dose of the recommendation (0 g/m2) (D1), 50% NPK fertilizer dose of the recommendation (198.5 g/m2) (D2), 100% of NPK fertilizer dose of the recommendation (397 g/m2) (D3), with 3 replications. DMRT test (Duncan, Multiple Range Test) was performed with a confidence level of 95% when the results between treatments were significantly different.
