The aim of this study was to determine the interaction between ameliorant andvarieties on soybean growth and P nutrient uptake in Ultisol soil at Warmare. This researchwas conducted using a randomized block design (RAK) in two factors, namely ameliorant(A) of manure as the main factor consisting of 3 levels including: A0 (without ameliorant),A1 (chicken manure) and A2 (goat manure). Soybean varieties (V) as the second factorincluded: V1 (Anjasmoro) and V2 (Wilis). The results showed that the interaction betweenameliorant and variety siginificantly affected plant height at 5 week, number of trifoliateleaves at 3 week, number of branches and nutrient uptake of P. Giving goat manureameliorant to Anjasmoro variety produced the highest plant (48.42 cm) at 5 week. Theapplication of chicken manure and goat manure to the Anjasmoro variety produced thehighest number of trifoliate leaves (5.00 pieces) at 3 week. In the variable number ofbranches, the Wilis variety which was given goat manure obtained the highest number ofbranches (5.66 branches). The highest nutrient uptake of P (9.77 g) was found in theAnjasmoro variety which was given chicken manure.

This research was conducted to determine the most effective concentration of young coconut water to increase the growth of land kangkung. This study used a regression analysis design, with 15 coconut water concentration treatments, namely: 0%; 7.14%, 14.28 %, 21.42 %, 28.56 %, 35.70 %, 42.84 %, 48.98 %, 57.12 %, 64.26 %, 71.40%, 78.54%, 85.68%, 92.82%, and 99.96%. The variables observed in this study included plant height, number of leaves, leaf area, fresh weight, and dry weight. The data were analyzed using linear regression to see the effect of coconut water concentration on the growth of land kangkung plants from 15 treatments. The results of the study found that the application of coconut water at various concentrations had a significant but negative effect on plant height at 2 and 6 week, number of leaves at 2 week, leaf area at 2 week, as well as wet weight and dry weight of plants at age 6 week.

This study aims to observe the growth of breadfruit root cuttings due to a combination of planting media and the application of growth regulators. The research was carried out experimentally using a randomized block design with 9 treatments, namely soil, soil + PGR soaking, soil + PGR powder dipping, husk + soil, husk + soil + PGR soaking, husk + soil + PGR powder dipping, sand + soil, sand + soil + PGR soaking, sand + soil + PGR powder dipping. The data obtained were analyzed statistically and test futhered by Tukey's honestly significant difference. The results found that there were significant different in the characters of shoot time, shoot length 1-6 WAP, number of shoots, and number of roots. The treatment of soil media and PGR dipping performed the fastest shoot time. On the other hand, a mixture of soil with husk and ZPT given by soaking showed the best shoot length. The most roots number was produced by the the cuttings planting in sand and treated by dipping PGR.

This study aimed to determine the potential of several isolates of Pseudomonas fluorescens group from the rhizosphere as biological agents in suppressing the growth of F. oxysporum f.sp. lycopersici in vitro. The method used in this research is an experimental method, by selecting several isolates of Pseudomonas bacteria group fluorescens that have the potential to control the pathogen F. oxysporum in vitro. The results showed that Pseudomonas isolates from fluorescens groups M1, M2, M3, and M4 had the potential to control the pathogen F. oxysporum f.sp. lycopersici in vitro by inhibiting the growth of pathogens. The average percentage of pathogen growth inhibition from the highest was isolate M2 (64.18%), isolate M3 (62.53%), isolate M1 (60.02%), and isolate M4 (60%).

This study aimed to identify the physical properties and soil pH of theManggoapi field experimental area, Faculty of Agriculture, which is being used bystudents, lecturers, or researchers for experimental activities of agricultural cultivation. Theresults found that the color of the soil ranges from dark brown to dark yellowish brown andthe soil color between the top layer and the bottom layer has blended due to frequent usedfor cultivation. Soil texture ranges from slightly coarse, medium and fine grades. The soilstructure ranges from globular, angular to granular lumps of medium to fine size, withmoderate to weak stability. The consistency of the soil is rather sticky and somewhatplastic, having a firmness that is loose to very loose. Surface rock is spread between 0-25%and rock outcrop 0-45%, with good drainage, and effective depth is more than 15.5 – 64.5cm. Soil pH is classified as neutral to alkaline.

This study aims to determine the response of growth and yield of sweet potato (Ipomoea batatas L.) to the application of several types of fertilizers on Inceptisol soil in Amban. Fertilizer application with the following doses: P0 = No fertilizer (control), P1 = NPK fertilizer (standard dose) 300 kg/ha = 225 g/mound, P2 = KCl fertilizer, 50 kg/ha = 375 g/ mounds, P3 = Papua nutrient granular fertilizer 300 kg/ha = 225 g/mounds, P4 = Papuan nutrient liquid fertilizers 10 liters/ha = 7.5 ml/mounds. P1, P2 and P3 treatments were carried out at 2 week after plant (WAP), while the P4 treatment was carried out at the age of 2, 4 and 6 WAP. The results showed that the application of several types of fertilizers did not have a significant effect on tendril length, tuber weight, wet weight and dry weight of tendrils in all observations. The analysis results of the soil chemical properties found that the soil pH was 4.63 (acidic), C-organic was 0.89% (very low), N-soil was 0.14% (low), Pavailable was 4.17 ppm (very low), and base saturation was 32.92% (low). The soil CEC was 4.94 cmol(+)/kg with exchangeable cations of kalsium, magnesium, potassium and sodium were 1.19 cmol(+)/kg (low), 0.34 cmol(+)/kg (very low), 0.07 cmol(+)/kg (very low) and 0.03 cmol(+)/kg (very low), respectively. The highest tendril length produced by KCl fertilizer, but Papua Nutrient granule yielded the best of average fresh weight of tendril, average dry weight of tendril, and tuber weight of sweet potato.
