Soybean is the most important food commodity besides rice and maize. Besides from being a source of vegetable protein, soybean is used as animal feed and raw material for processing industrial of soy sauce and soymilk. Land in Palangka Raya is peat soil that mostly high level of acidity. This constraint for agriculture development because of low availability of plant nutrients. One attempt to overcome this obstacle is the application of oil palm bunch ash (OPBA).The aim of this study was to analyse the interaction between the time application and doses of OPBA on the growth and yield of soybean in peat soil. The research was conducted on peat soil in the Bereng Bengkel village, Sebangau subDistrict, Palangka Raya using randomised block design (RBD) with two factorialtreatments. The first factor is the timing of OPBA application which consists of two levels i.e., two weeks before planting (WBP) and tree WBP planting. The second factor is the OPBA dosage which consists of four levels i.e., without OPBA, 250 kg/ha, 500 kg/ha and 750 kg/ha. Each treatment was repeated three times so that there were 24 experimental units. The experimental results showed the interaction time of timing and OPBA dosage on peat soil was highly significant; the number ofeffective root nodules on five weeks after planting (WAP) observation. The single factor of OPBA application time has very significant effect on a number of effective root nodules age five WAP, days to flowering and number of pods per plant. While single-dosage factor OPBA has very significant effect on the number of root nodules on five WAP observation, broad leaf age nine WAP, days to flowering and number of pods per plant

Long beans is one of the vegetable plants favored by the wider community, other than that the root nodules of this plant it capable to be a symbiosis with rhizobium bacteria to nitrogen fixationinto the soil so that the existence of nitrogen elements in the soil can be maintained, this is also accompanied by increased weed growth around the long beans so it will be affected the growth and yield of long beans crops.Research aimed to determine effect which caused by the existence of weeds on productivity of long beans (Vigna sinensis L.). Research was conducted on June 2016, North Sangatta Subs-district. The experiment was set up as a non factorial in a complete randomized block design which consists 5 blocks and 5 treatments, (P1) 100% weed existence, (P2) 75% weed existence, (P3) 50% weed existence (P4) 25% weed existenceand (P5) 0% weed existence. The Obtained results were analyzed by analysis of variance. The results showed that there was non significant on plant aged parameters when flowering 80%, plant aged at the time of first harvest and crop production, while the weight of fruit per plant was significantly. The best yielded when plant aged of 80% flowering on treatments of 100% weed existence and 25% weed existence i.e. 36,00 days;plant aged on the fastest harvest resulted ontreatments of 75, 25 and 0% weed existencei.e. respectively on 47and 20 days. Long beans has the the heaviest fruits were produced on the treatment of 0% weed existence i.e. 0,528 kg. While the heaviest production were produced on the treatment of 0%weed existence i.e.4,586 tonsha-1. Weeds that dominate on the planting area of long bean wereCyperus rotundus with the summed dominance ratio (SDR) 32,86%, there is decrease of production as 2,246% from total production if weed control is not done it.

Temulawak is rarely cultivated with any intensity because it has a long harvest time and requires wide spacing. One of the solutions for temulawak cultivation is through applying intercropping systems with corn. The current research aimed to determine the most advantageous intercropping planting pattern of temulawak and corn. The experiment adhered to a randomized block design with six treatments and four replications. The treatments were: T1 = strip cropping; T2 = row cropping; T3 = strip-relay temulawakcorn; T4 = row-relay temulawak-corn; T5 = strip-relay corn-temulawak; and T6 = rowrelay corn-temulawak. The results showed that different cropping patterns of an intercropping system of temulawak and corn affected the growth and yield of both crops. The most suitable polyculture cropping pattern, based on land equivalence ratios (LER) values and R/C ratios, was strip cropping that produced rhizhomes of temulawak of up to 2.68 ton ha-1 and of corn of up to 5.24 ton ha-1. The LER value was 1.22 and the revenue/cost (R/C) ratio was as much as 1.43 with a net profit of as much as IDR 9,509,000.

<p><em>Efforts to increase the growth and yield of soybean plants can be done through the use of cultivation technology,  namely  by  providing  biological  fertilizer  treatments  such   as  N-fixing  bacteria,  namely Rhizobium. The study aims to determine the effect of the right Rhizobium dose and type of NPK fertilizer on the growth of the Anjasmoro variety of soybean (Glycine max). This research uses a factorial randomized block design with two factors and three repetitions. The first factor is Rhizobium inoculation consisting of I0: No inoculum, I1: Rhizobium inoculum (5 g / kg seed), I2: Rhizobium inoculum (7 g / kg seed), I3: Rhizobium inoculum (9 g / kg seed). The second factor is the type of NPK fertilizer, namely P0: No fertilizer, P1: solid NPK fertilizer (0.8 g / plant), P2: liquid NPK fertilizer. The results showed that the dose of Rhizobium that could affect soybean growth was a dose of 9 grams/kg of seed that significantly affect ed the number of leaves and leaf color but did not significantly affect plant height, number of branches, number of root nodules and root nodules weight. NPK fertilizer that can affect soybean growth is liquid NPK fertilizer, and only has a significant effect on leaf color. The interaction of Rhizobium inoculation treatment and NPK fertilizer types significantly affected most parameters but did not significantly affect the number of branches and weight of root nodules.</em></p>

Information on the most suitable and high-yielding cayenne pepper variety for an off-season growing in dryland is important. This research aimed to examine the effect of foliar fertilizer on growth and yield of off-season cayenne pepper in dry land. The experiment was conducted during the rainy season of 2020/2021 in a dryland with a sandy loam soil texture in the area of Gumantar, North Lombok, Indonesia. Four cayenne pepper varieties, namely Dewata 43 F1, Pelita F1, Taruna, and Sret, were treated with three concentration levels (0%, 0,5%, and 1,0%) of organic foliar fertilizer. The treatments were arranged in a factorial randomized block design with three replications. The results revealed that application of foliar fertilizer increased number of flowers and yield, and reduced flower abortion. Pelita F1 yielded the highest, 11.5% higher than Dewata 43 F1 and three-fold higher than that of the non-hybrid varieties when treated with 1.0% of fertilizer. Dewata F1 was harvested at 70 days after transplanting (dat), followed by 76, 105 and 105 dat for Pelita F1, Sret and Taruna, respectively. To maximize the use of the rainfall and prolong the harvest time, Pelita F1 and Taruna varieties are highly recommended for dryland areas.
