Acidic dry land is a potential suboptimal land as a source of agricultural production with proper management and utilization. The aim of this research is to determine the growth response and soybean yields of Kipas Merah and Demas varieties to several fertilizer packages. This research was conducted in July to October 2018 in Pidie Jaya Regency of Aceh Province. The study design used a randomized block design (RBD) with 3 replications and in each treatment set 15 plants as samples. The first factor is the variety (V), that is V1 = Kipas Merah; V2 = Demas. The second factor is fertilization package (P) consisting of 2 (two) levels: P1 (specific location) (2 tons/ha organic fertilizer, ameliorant 500 kg/ha and NPK 150 kg/ha); P2 (Recommendation) (urea 75 kg/ha, SP-36 100 kg/ha, KCl 100 kg/ha, ameliorant 500 kg/ha). The results showed the Demas variety with the recommended package gave the highest production of 1.97 tons/ha.
[IMPROVEMENT OF PEANUT GROWTH AND PRODUCTIVITY IN DRY LAND THROUGH THE APPLICATION OF DOLOMITE AND NPK FERTILIZERS]. Dry land is commonly characterized by low pH and nutrient availability for peanut growth. Therefore, application of dolomite and NPK fertilizer might correct its characteristics. This study aimed to determine the appropriate dose of dolomite and NPK fertilizers to increase growth and productivity of peanut in dry land. This study was carried out from November 2019 to February 2020 at the Meteorological, Climatological, and Geophysical Agency, Indrapuri Experimental Garden, Aceh Besar, Aceh and used a randomized block design (RBD) with two factors and three replications. The first factor was three dosages of dolomite (i.e., 0, 250, and 500 kg/ha) and the second factor was three levels of NPK fertilizers (i.e., 0 kg/ha Urea+ 0 kg/ha SP36+ 0 kg/ha KCl), 25 kg/ha Urea + 50 kg/ha SP36 + 50 kg/ha KCl, and 50 kg/ha Urea + 100 kg/ha SP36 + 100 kg/ha KCl). The results showed that application of dolomite or NPK fertilizers had a significant effect on peanut yield components. Application of dolomite at 500 kg/ha or NPK fertilizers at 50 kg/ha Urea + 100 kg/ha SP36 + 100 kg/ha KCl increased peanut productivity by 10% and 9.23%, respectively compared to the control.
Aceh is one of the centers for hybrid maize production with an area of 47,160 ha and a production of 205,125 tons. Increased production of maize can be achieved by applying technological components, including the use of superior varieties and recommendations for fertilization and spacing to obtain maximum results. The purpose of this study was to determine the response of growth and yield of three high yielding varieties of hybrid maize to the fertilization package. This research was conducted from July to October 2019 in Bireun District, Aceh Province. The research used a randomized block design (RBD) with 3 replications and for each treatment 15 plants were assigned as samples. The first factor is the variety (V), namely V1: Pioner 32; V2: Bima 19, and V3: Bima 20. The second factor is the fertilizer package (P) which consists of 2 (two) levels: P1 (recommendation) (urea 270 kg / ha, NPK 400 kg / ha, KCl 50 kg / ha); P2 (specific location) (urea 150 kg / ha, SP-36 75 kg / ha, NPK 300 kg / ha). The results showed that the Bima 20 variety with the recommended fertilizer package gave the highest production of 8.03 ton/ha.
Soybean is an important commodity needed by people in Indonesian. Soybean production is currently decreasing every year because off decreasing land area. The available land in Indonesia is mostly used by farmers to cultivate crops that have the potential to meet their economic needs, so that very few farmers use their land for soybean crops. This study aimed to determine the adaptation of shade-tolerant soybean varieties to fertilization technology at various levels of shade coconut plant. The research was conducted at Bandar Baru District, Pidie Jaya Regency, Aceh Province on July to October 2019, with split plot design. The main plot is shade (N), namely N1: 0% shade (without shade); N2: 25% shade and N3: 50% shade, and subplot is the fertilizer package (P) namely P1: recommendation (NPK 150 kg ha-1, organic fertilizer 2 t ha-1); P2: specific location (urea 75 kg ha-1, SP-36 100 kg ha-1, KCl 100 kg ha-1). The results showed that the level of shade had no effect on soybean production, while the fertilization factor showed that the highest production was found in the recommended fertilizer package 1.82 t ha-1, different with the specific location fertilizer package.
The conversion occurrence of agricultural land has a significant effect on the decline in soybean production, so that the use of coconut land with a double cropping system to increase national soybean production. Soybean cultivation in agroforestry systems can be applied to soybean cultivation systems under shade with shade-tolerant varieties. This study aims to determine the growth and yield of soybean varieties at various levels of shade of coconut trees. The research was carried out in Paru Keude Village, Bandar Baru District, Pidie Jaya Regency, Aceh, carried out in April – September 2019, with a Split Plot Design. The main plot is shade (N) consisting of no shade (N1), 25% shade (N2) and 50% shade (N3), and the variety plot (V) consists of Dena 1 (V1), Anjasmoro (V2) and Fan Red (V3). The study was analyzed by ANOVA, if the F value was greater than the value in the F table, it was continued with Duncan's Multiple Range Test at a significance level of 95%. The results showed that the Kipas Merah variety had higher plant height than Dena 1 and Anjasmoro, but Dena 1 had higher production at each shade level compared to Anjasmoro and Kipas Merah. Thus, the Dena 1 variety was able to maintain production at all shading conditions.
Yield Performance of Inpago 9, Inpago 11, and Unsoed Varieties Dryland Rice in Aceh Province. The availability of large areas in dry land is not a limited factor in efforts to develop rice in Aceh. One of alternative in the development of rice cultivation in dry land can be done by using drought resistance varieties. The purpose of this study was to assess the best adaptive varieties to drought which can increase rice yield, thus it can be recommended to farmers to be developed in dryland. The study was conducted in dry land in Krueng Meriam Village, Tangse Sub district, Pidie District with an area of ± 2 ha from March to December 2018. The experimental farm design used was factorial Randomized Block Design (RBD) with three replications. The first factor was variety (V) consisting of 3 levels, namely V1 = Inpago 9, V2 = Inpago 11, V3 = Unsoed, while the second factor was the dose of fertilizers (P) which consisted of 2 factors namely P1 = Specific Location (Urea 200 kg/ha, NPK = 200 kg/ha) and P2 = Recommendation (Urea 250 kg, NPK 300 kg/ha). Data were analyzed using Microsoft Ecxel. Observation parameters included growth and yield components. The results showed that Inpago 9, Inpago 11 and Unsoed varieties displayed a high agronomic character and the number of tillers differed from one another, but the yield was not significantly different which was 4 tons/ha. All three varieties are adaptive to dry land in Aceh.
