Optimization of elements of varietal agricultural technology in potato cultivation
Authors: Shabanov Adam Emirsultanovich 
Published: February 2022

The research was carried out in 2018-2020 on a new early potato variety Azart in Russian Potato Research Centre in the conditions of sod-podzolic sandy loam soils of the Central region of the Non-Chernozem zone. In the experiment, we studied a complex of agrotechnical techniques, including the timing, density of planting and methods of applying mineral fertilizers in order to accelerate growth, subsequent development, increase plant productivity and uninterrupted supply of nutrients throughout the growing season. It was found out that early planting accelerated the emergence of seedlings by 6-7 days, and the onset of the budding and flowering phase of plants by 4-6 days. The mass of the tops, and the area of the assimilation surface of the leaves increased by 1.5 t/ha and 2.6 thousand m2 / ha. The yield increase from early planting for an average of 3 years reached up to 1.8 t/ha or 4.5%, and from fractional fertilization up to 2.1 t/ha or 5.3% in comparison with the corresponding controls. The combined use of agricultural techniques in the experiment allowed us to obtain a yield increase of 3.7 t/ha or 9.7%. Conditional income amounted to 39 thousand rubles/ha, and the cost price – 3.7 rubles/kg, which is 0.3 rubles/kg less than in the control. Thickening of plantings to 50 and 56 thousand tubers/ha contributed to an increase in the yield of tubers by an average of 2.8-3.3 t/ha or up to 8.7%, compared with the control. Conditional income increased on these options to an average of 8.0 thousand rubles/ha.

Seagrass is an ecosystem that has an important role as nursery and spawning ground in the life cycle in the sea. Increased human activity and climate change are feared to damage seagrass ecosystems so it is important to maintain their sustainability. This study aims to find out the composition of species, density and coverage of seagrass at Tunggul Beach, Paciran, Lamongan. This research was conducted on August until October 2020 by applying purposive sampling method as the basis for determining location point at 2 stations, with 3 substations at each station with transect line along 100 m. Seagrass data retrieval method using transect quadrant 50 x 50 cm to observe the coverage and calculate seagrass stand. The results showed the type of seagrass found on Tunggul Beach are two species, Thalassia hemprichii and Enhalus acroides. Seagrass density value at station 1 is rather tight with a density value of 92.48% and at station 2 is rare with a value of 73.09%. The percentage of seagrass coverage at station 1 indicates a solid category with a coverage value of 54.92% and in the station 2 shows a medium coverage category with a value of 31.25%.

Dan variabel manakah yang berpengaruh dominan terhadap minat beli konsumen pada distro-distro di Mataram?. Tujuan penelitian ini adalah untuk mengetahui bagaimana Pengaruh Store Atmosphere Terhadap Minat Beli Konsumen. Jenis penelitian yang akan dilakukan bersifat asosiatif kausal dengan jumlah responden sebanyak 160 orang responden. Untuk menganalisis pengaruh store atmosphere digunakan Uji Asumsi Klasik, Analisis Regresi Linier Berganda dan Koefisien Determinasi Berganda (R2). Adapaun pembaharuan dari penelitian terdahulu yang digubnakan dalam penelitian ini meliputi; pembaharuan variable devenden dan indevenden, analisis data dan jumlah responden yang digunakan.
Secara umum semua variabel independen pada penelitian ini berpengaruh namun tidak signifikan terhadap minat beli konsumen pada distro-distro di Mataram.
