Shallot is an important commodity that becomes the basic food needs of the Indonesian people. Farmers generally use chemical or inorganic fertilizers in their cultivation activities. Inorganic fertilizers can accelerate the growing period because the nutrients can be absorbed directly by the soil. However, the continuous use of inorganic fertilizers can harm the soil and the environment, then to avoid this is to switch to using organic fertilizers. Manure is one of the organic fertilizers that can increase the availability of nutrients for plants. With the presence of intensive bacteria, it can accelerate the availability of nutrients. Bacteria whose role is to decompose organic matter are called PGPR. This study aims to (i) know the interactions (ii) know the single factor of cow manure (iii) know the single factor of bamboo root PGPR (iv) get the best interaction (v) get the best dose of cow manure (vi) get the best dose of bamboo root PGPR. This research was carried out in alluvial land in Tabalong District from March-June 2019. This study used a factorial randomized block design with the treatment is a dose of cow manure, namely: p1=10 t/ha, p2=20 t/ha, p3=30 t/ha, while the bamboo roots PGPR are: b1=20 ml, b2=25 ml, and b3=30 ml, so the combination is 9 treatments. The results showed that the observed variables were plant height, number of leaves, number of tubers, tuber diameter and tuber weight only affected plant height with a single factor treatment of cow manure and the best dose was 20 t/ha.Shallot is an important commodity that becomes the basic food needs of the Indonesian people.

Lebak wetland is land that has many limiting factors for the development of food crop cultivation, especially maize. These limiting factors include excess water, varied soil fertility and toxic elements. Efforts that can be made to increase corn production are by using the right varieties and providing fertilizers, especially using biological fertilizers. This study aims to determine (i) the effect of two sweet corn varieties on several doses of biological fertilizers, (ii) the influence of varieties, (iii) the effect of doses of biological fertilizers, (iv) the interaction of varieties with biological fertilizers, (v) the best varieties and (vi ) the best dosage of biofertilizer on the growth and yield of two varieties of sweet corn. The study was conducted in Pasar Senin Village, Amuntai Tengah District, Hulu Sungai Utara Regency from April to July 2017. Using a Randomized Block Design (RBD) Factorial 2 factors. The first factor is sweet corn varieties, namely v1 = Bonanza F1 and v2 = Valentino F1. The second factor of the dosage of biological fertilizer is: h0 = 0 kg.ha-1, h1 = 50 kg.ha-1, h2 = 100 kg.ha-1 and h3 = 150 kg.ha-1. The results showed no interaction of varieties with fertilizers on all observation variables, varieties had an effect on plant height, number of leaves, stem diameter, ear weight with straws and without weight, ear length with straws and without cornhusk and diameter with strawberries and without nuts with the best treatment is v1, while biofertilizer influences the weight of the cob with the weight, the length of the cob with the straw and without the weight and diameter of the cob with the kelobot and without the kelob with the best treatment is h2.

Along with the increasing demand for palm oil has the world's population, it is necessary to think about efforts to increase the quality and quantity of palm oil production. One of the factors such as planting material in the form of seeds, it is necessary to act technical culture or good seed treatment. Oil palm seedlings can be done in two stages: initial seeding (prenursery) and moved at the age of 2.5-3 months when they fulfill the criteria nursery ready to move to the main (main nursery). This study aims to (i) determine the speed of growth of oil palm seeds and, (ii) obtain the best type of soil for growing speed of oil palm seeds in two places making swampy marshland. The research was conducted in the Pangkalan Sari Village, Sungai Pandan Sub-district, Hulu Sungai Utara Regency in July-August 2013, using a completely randomized design (CRD) with a single factor. Factors studied were two lebak wetland of origin of uptake (T) as much as two levels and repeated nine times. The results showed that the two treatments had no effect lebak wetlands on many shoots observation variables age 14 and 28 days after seeding(DAS), the amount of leafage of 14 DAS, seedling height 14 DAS, and significant observations on many variables shoots the age of 42 DAS, number of leaves age 28 and 42 DAS, and a very significant effect on seedling height observation variables age 28 and 42 DAS.

Alabio yam is one of the alternative food helpers during a famine when rice, sago, and others cannot be harvested, alabio yam can be a healthy food, but farmers do not cultivate alabio yams to the maximum because farmers do not do fertilization and less optimal soil cultivation to improve it there is a need for good fertilization and tillage. This research was conducted in the Banyu Tajun Hulu Village Sungai Pandan District Hulu Sungai Utara District with the title Use of kayambang bokashi on alabio yam cultivation with land management from February to August 2019. using a factorial randomized block design (RBD) with 2 treatment factors, 1 kayambang bokashi and 2 land processing. The first factor is the dose of bokashi kayambang which consists of 5 levels, namely b1 = 5 tons. ha-1 equal with 0.5 kg. plot-1, b2 = 10 tons. ha-1 equal with 1 kg. Plot-1, b3 = 15 tons. ha-1 equal with 1.5 kg. plot-1, b4 = 20 tons. ha-1 is equal to 2 kg. Plot-1, b5 = 20 tons. ha-1 equal with 2.5 kg. plot-1. The second factor consists of 2 levels, namely, t1 = minimum land processing, t2 = maximum land processing. The results showed that the interaction between bokashi kayambang and land management only had a significant effect on the observation of 30 HST. The single factor of bokashi kayambang has a very significant effect on all observational variables. The single factor in land processing only had a significant effect on leaf observation at 20 HST.

Lebak wetland can generally be used as vegetable cultivation land with proper handling. Lebak wetland land has a complex chemical problem. Giving organic material is one way to improve some soil chemical properties. The aim of this research is (i) to know the effect of guano organic fertilizer on the growth and yield of cucumber plants on  lebak wetland (ii) to get the best dose of guano organic fertilizer on the growth and yield of cucumber plants on lebak wetland. The research was conducted in the Pasar Senin Village, Amuntai Tengah District, Hulu Sungai Utara Regency from May - July 2012. This study used a randomized block design (RBD), with 5 treatments and 5 replications, so there are 25 units, and each treatment there are 4 plants. Factor test in the guano organic fertilizer that g0 = 0 kg.plot-1, g2 = 0.5 kg.plot-1, g3 = 0.1 kg.plot-1, g4 = 1.5 kg.plot-1 and g5 = 2 kg.plot-1 . Results of this study showed that treatment dosing guano organic fertilizer which was highly significant on plant height ages 7, 14 and 21 DAP, number of leaves aged 7, 14 and 21 DAP, number of fruits, fruit weight and length of the fruit. The best dose of guano organic fertilizer is 10 t.ha-1 equivalent to 1 kg.plot-1 (g2).
