Pandemi Covid-19 mengggu kgiatan masyarakat. Tujuan penelitian untuk meningkatkan pertumbuhan dan produksi tanaman selada di pekarangan rumah masarakat desa.Tempat Penelitian di Desa Nusajaya Halmahera Timur Indonesia. selama Januari – Mei 2021. Perlakuan tanpa pupuk orgnik cair limbah ikan ((POCLI)) 1 liter air/3 polybag (A1)., (POCLI) 5 cc/1 liter air/3 polybag (A2)., (POCLI) 10 cc/1 liter air/3 polybag (A3)., (POCLI) 15 cc/1 liter air/3 polybag (A4)., (POCLI) 20 cc/1 liter air/3 polybag (A5)., (POCLI) 25 cc/1 liter air/3 polybag (A6) Masing- masing polybag diberikan 333 cc. Parameter agronomi meliputi: 1) Tinggi selada (cm), 2) banyak daun selada, 3) Panjang (cm), 4) Bobot segar sampel (g) dengan analisis ragam (Anova). Kesempulan. Hasil analisis ragam menunjukan bahwa perlakuan POCLI 25 cc/L air/3 polybag (A6) berpengaruh terhadap seluruh parameter pengamatan selada, umur 14 HST tinggi 8 cm, umur 21 HST tertinggi 13 cm dan pada umur 28 HST tinggi 20 cm. Pada saat panen menhasilkan jumlah daun selada terbayak 10 helai, daun terpanjang 20 cm, dan bobot sampel terberat 135 g bila dibandingkan dengan perlakuan lainnya. Usur makro dan mikro didalam POCLI sehingga mendorong, mempercepat pertambahan ukuran, panjang selada.
Batang bawah berpengaruh terhadap tingkat keberhasilan kompatibiltas secara vegetatif melalui metode grafting. Mengetahui salah satu umur batang bawah terbaik yang menentukan tingkat persentase keberhasilan metode grafting menjadi tujuan penelitian ini dilakukan. Metode yang digunakan adalah Rancangan Acak Kelompok dengan 3 perlakuan perbedaan umur batang bawah 60 hari, 90 hari dan 120 hari. Hasil penelitian bahwa perbedaan umur batang bawah mempengaruhi 90% keberhasilan pembiakan vegetatif metode sambungan terhadap kemunculan tunas baru dan jumlah daun. Persentase kerberhasilan tertinggi pada perlakuan bibit batang bawah umur 60 hari (48,75%). Jumlah daun tertinggi pada perlakuan umur bibit pala 60 hari (6 helai) sedangkan yang terendah pada perlakuan umur bibit pala 120 hari (3 helai).
The purpose of this study to determine the effect of the Portulaca oleracea purslane growth time on the growing and production of Topo local cultivar of red onions Allium ascalonicum which is originally from Tidore island. We used Randomized Block Design (RBD) to run six treatments in three blocks which consisted of P0 (without purslane weed as the control), P1 (purslane growth in the beginning of onion planting), P2 (growing of purslane after 10 days planting of onion), P3 (growing of purslane after 20 days planting of onion), P4 (growing of purslane after 30 days planting of onion), and P5 (growing of purslane after 40 days planting of onion), so there were 18 experimental units. Then, data were analyzed by ANOVA, if there any significant effect which was continued by Least Significance Different test (ɑ = 0,05). The results showed that the longer purslane weeds associated with Topo red onion could suppress the growth of this red onion and finally decrease the production. Finally, we found that production of P2 (103.33 g/plot) as the lowest production, which differed significantly with P0 (483.33 g/plot). Therefore, we suggested if weed control of purslane could be done at the age seven until forty days after planting and this information could be used as an essential strategy to controlling purslane weed.
Crop area estimation and identification of drivers for land-use change are crucial for efficient crop management and decision-making in agriculture. Remote Sensing techniques are now being used to estimate crop area and production monitoring globally, including developing countries. In Bangladesh, rice area estimation has traditionally been done through location-based field visits or eyeestimation, which is tedious and time-consuming. The present study uses Remote Sensing (RS) and climate parameters to explore the cultivation area and driver of boro area expansion in Tangail Sadar Upazila. Multi-spectral Landsat imageries were obtained from 1999 to 2020 at the maximum growth stages of boro rice. Upazila's boundary was clipped over the images using a shape file created from Bangladesh map. The images were analyzed with QGIS, ArcGIS, and R software through the Random Forest (RF) supervised classification. Standardized Precipitation Evapotranspiration Index (SPEI) was calculated using monthly total rainfall; minimum and maximum temperature to observe drought impacts. The findings revealed that the boro rice cultivation gradually increased from 8104 ha (in 1999) to 12781 ha (in 2020). In 2009-20, the expansion rate (3.10 percent) of boro rice areas was much lower (11.49 percent) than in 1999-2009. It was due to relatively stable boro cultivation in the recent decade. The Overall accuracy was 93-96 percent with the kappa coefficient of 0.90-0.93. The study showed that there was a good relationship between satellite and traditionally estimated boro rice area. The expansion of boro rice areas has been driven mainly by the positive impacts of climate change. Long-term hydrological drought and a shorter wet spell have introduced boro rice cultivation to the lowlands and river basin areas. According to the benefit cost ration (BCR), growing mustard and boro rice in the same season was more profitable than growing any sole crop. The study revealed that remote sensing was effective for exploring boro rice cultivation area and driver of expansion.
Cucumber is fruit consumed by straight away. Destination how waste vegetables increase growth and production cucumber (Cucumis sativus L.).
