Intercropping system that involves planting multispecies between accumulator plants and cultivated plants is a way to improve the phytoextraction of heavy metals in agricultural land simultaneously. However, how the effect of accumulator plants on the growth and yield of cultivated plants has not been widely studied. This study aims to determine the growth and yield of vegetables intercropped with accumulator plants from the legume group, namely Crotalaria juncea L. The study was carried out using a randomized block design with one factor, namely Chinese vegetable monoculture (P1), bean vegetable monoculture (P2), and accumulator plant monoculture. Crotalaria juncea L. (P3), an intercropping system between Chinese cabbage and Crotalaria juncea L. (P4; and an intercropping system of beans and Crotalaria juncea L (P5). The results showed that in Chinese cabbage, monoculture planting produced biomass and crop yields. per plant and per plot was higher than the crops grown by intercropping. In the bean crop, monoculture and intercropping systems did not provide differences in biomass yield and fruit yield per plant and per plot. Crotalaria juncea L, which was grown in monoculture produced plant biomass and the yield of the stove per square is higher gi compared to those planted by intercropping. Crotalaria juncea L. intercropped with Chinese cabbage was able to accumulate more Pb in the roots, while Crotalaria juncea intercropped with chickpeas accumulated higher Pb in the stems. Crotalaria juncea plants grown in monoculture accumulated higher Pb than those intercropped with vegetables, so further research is needed to test the effective removal of Pb using other cropping systems.

   Pakcoy is a type of mustard plant that is quite popular with the community, it is very suitable to be cultivated considering the need for vegetables is quite large. The community's need for fresh and pesticide-free vegetables is a choice now in line with the community's understanding of a healthy diet. Alternatives to fulfillment are chosen by planting with hydroponic media. Hydroponics is a substitute for soil media that can be used to grow vegetable crops. The presence of hydroponics is expected to be able to overcome the narrowing of agricultural land and reduce the use of pesticides considering that pesticides greatly affect human health and the environment.   This study aims to determine the effect of nutritional doses of AB mix agrifarm and age of seedlings and their interactions on the growth and yield of pakcoy plants, this study is carried out in the experimental garden of the Faculty of Agriculture, Tabanan University which began on 9 December 2018 until 12 January 2019.   The study used a Randomized Block Design (RBD) consisting of two factors. The first factor is the nutritional dose of AB mix agrifarm (N) which consists of three dose levels, namely the dose of 850 ppm, 1050 ppm and 1250 ppm. The second factor is the age of seedlings (U) which consists of two seedling age levels, namely the age of seedlings 1 week and 2 weeks. Each treatment is repeated four times.   The results of the study obtained the interaction of dose agrifarm treatment with seed age showed a very significant effect (p 1 0.01) on all parameters except for the parameters of the number of leaves aged 35 days old which showed no significant effect (p 5 0.05). The economical wet weight of plant-1 and BKO of the highest yield of 1-crop yield is produced in the combination treatment of N3U, which amounted to respectively 244.09 g and 78.10g or increased respectively by 57.78% and 293.85% compared to results the lowest produced by the combination treatment of N1U1 is 154.71g and 19.83g

Weeds are not always detrimental to plants, because there is a period of time when they are most influential on plant growth and yield and a period of time when weeds are present is called critical piriode. A research aimed to determine the critical period of sweet corn with weeds in Central Lombok entisoles. The experimental research method with experiments in the field used a randomized block design (RBD), which consisted of 12 treatments, weed-free plants (TBG) from planting to age, 10;20;30;40;50 and 60 days and the plants were allowed to roll (TG). since planting until the age of 10;20; 30; 40;50 and 60 days. The results showed that the presence of tolerable weeds on sweet corn plants was only until the age of 30 days after planting. Weeds must be weeded after the plants are between 30-40 days old, if done after the plants are 40 days old, the crop yields cannot be saved. The critical period for sweet corn competing with weeds on the Lombok Tengan entisol is in the age range between 30-40 days after planting. Plants that compete with weeds for 40, 50, and 60 days after planting (until harvest) experience a decrease in yield of 60.32%, 82.84% and 98.66%. Meanwhile, plants that did not compete (weed free) for only 10, 20 and 30 days experienced a decrease in yield of 98.61%, 80.16% and 61.40%.

Organic matter content in the dryland farming system tends to decrease rapidlyin most of arid region of Eastern Indonesia. This experiment aimed to test that hypothesis by growing casava and mungbean with and without organic fertilizer (cattle manure) under monoculture and intercropping. The study used a factorial completely randomized block design. The first factor is two cropping systems, namely monoculture and intercropping, the second factor is 2 applications of organic fertilizer (compost), namely 1) No compost and 2) Compost. Each treatment uses 6 replications. The results showed a significant effect of treatment on cassava yield component and productivity, while mungbean growth and yield was similar between treatment. Cassava grown under intercropping system with additional cattle manure was significantly produced the longest tuber (71.40 cm) and the largest number of tubers (6.40 tubers.plant-1). It also contributed to the highest tuber productivity (28.40 t.h-1), followed by yield of casava under intercropping system without compost (26.00 t.h-1), then the casava monoculture system with compost (21.80 t.h-1). The least was the monoculture system without compost (21.70 t.h-1). This experiment proved that additional organic fertilizer under intercropping system could increase the productivity of dryland (LER = 2.13).

Green mustard (Brassica juncea L.) is a popular vegetable among the people. Green mustard leaves are commonly used as complementary ingredients such as chicken noodle, meatballs, etc. These vegetables are easily accessible to traditional markets, supermarket, and mall. The main obstacle in cultivating green mustard is Plutella xylostella attack. P. xylostella pests can attack both vegetative and generative, striking at the shoots and leaves of plants from breeding to harvesting. One of the effective and safe controls is the bioinsecticide Bacillus thuringiensis. Tukungan soil is a swamp land management technology that aims to diversify commodities that can be planted. This technology is very helpful in utilizing and maximizing existing agricultural land, especially in South Kalimantan. The bioinsecticide material used is a strain of B. thuringiensis which is the Turex WP. This research aims to determine the best dose of bioinsecticide B. thuringiensis (Turex WP) in controlling P. xylostella pests, increasing growth and yield of green mustard in tukungan soils. The research used a one-factor randomized block design, namely the dose of bioinsecticide (Turex WP) consisting of five treatments: p0 = 0 g/L, p1 = 0.5 g/L, p2 = 1 g/L, p3 = 1.5 g/L, and p4 = 2g/L. The results showed that the bioinsecticide B. thuringiensis (Turex WP) with a dose of 2 g/L was effective in controlling P. xylostella pests, increasing growth and yield of green mustard in tukungan soils.

The Application of High Puddle and Organic Fertilizer on Rice Yield Ciherang Variety. Rice (Oryza sativa L.) is the staple vital food of Indonesian people. National rice production has not been able to meet the needs of the population, despite many efforts such as the use of improved varieties, fertilization, the use of agricultural machinery, and the use of pesticides. This study aimed to determine the effect of water level and organic fertilizers on crop yields of rice. This experiment used randomized block design in a simple treatment, namely the combination of the water level and the dose of organic fertilizer. This research using analysis of variance (ANOVA) to determine the effect of treatment on the variables tested. If treatment significant it will be followed by LSD test 5%. The results showed that the treatment of combination of water level and organic fertilizers provide a very real effect on the growth and yield of rice (Harvest dry grain yield ha-1). Harvest dry grain yield ha-1 obtained at the highest AMP2 treatment, namely without flooding water and organic fertilizers and 6 t ha-1 at 10.92 t ha -1 were significantly higher 70.09 % compared to the treatment of farmers. Based on the research results, it can be recommended that the application of water-saving cultivation of organic fertilizer with a dose of 6 t ha -1 needs to be done to improve rice yields.

Biological Potential

In Ukraine 57.5 % of agricultural land is subjected to erosion with 10–24 million tons of humus, 0.3–0.96 million tons of nitrogen, 0.7–0.9 million tons of phosphorus and 6–12 million tons of potassium lost annually. Degradation processes are also common on chernozems, which cover about 60 % of the Ukrainian territory. The aim of the research is to defi ne the most eff ective soil conservation practices and legislative decisions aimed to conservation/recovering the Ukrainian chernozem fertility. The experimental data of the agrochemical certifi cation of Ukrainian lands, data from scientifi c papers, stock and instructional materials as well as our own fi eld and laboratory studies were used. It has been established that the long-term use of deep subsurface tillage on typical chernozem increases, compared with plowing, the content of 10–0.25 mm of air-dry and water-resistant aggregates, the bulk density, soil water storages, water infi ltration rates, the content of mobile phosphorus and exchangeable potassium, pHH2O, CaCO3 stocks, the contents of humic and fulvic acids, molecular weights of humic acids – by 5.5 and 3.06 %; 0.05 g/cm3; 25.5 mm; 22.6 mm/h; 0.1 and 3 mg/100 g of soil; 0.03 pHH2O; 18 t/ha, 0.02 and 0.04 %, 91195 kDa, respectively. Fertilizers may contribute to the crop yields increase from by 60% in the Polissya, by 40 % – in the Forest Steppe, by 15 % – in the Wet Steppe, by 10 % – in the Dry Steppe and by 40 % – in the Irrigated Steppe areas. In soil-conservation rotations, the crop placement and alternation are advisable to combine with strips or hills sowing, taking into account the local relief features; soil alkalinization, applying anti-erosion structures. Ukrainian agriculture will receive additional 10–12 million tons of forage units or 20–22 % from all fodder in a fi eld agriculture under increasing 8–10 % of arable lands for intercrops. It is advisable to mulch the eroded chernozems of Ukraine depending on their texture composition: 1.3 t/ha of mulch for sandy and loamy soils, 1.9 t/ha – for sandy and 1.1 t/ha – for loamy soils. The implementation of soil conservation agriculture can minimize some soil degradation processes and improve eff ective soil properties required to realize the biological potential of cultivated plants. Key words: chernozem, degradation, fertility, soil conservation technologies, agriculture policy.
