“…Such beneficial effects of mulching have been demonstrated in the results achieved by Bijeta and Raghav [12]. Potato is reported to increase tuber yield when plants are mulched with plastics and straw mulch compared with plants grown in bare soil [13]. Total number of tubers decreased with delayed planting as compared to the optimum date of planting.…”

The present research work was conducted at Pili kothi farm, Department of Agronomy, Tilak Dhari Post Graduate College, Jaunpur, Uttar Pradesh during winter season of 2018 and 2019. The experiment was laid out in Factorial Randomized Block Design. The treatments comprised of different planting dates viz. 20 days early planting on 17th October, 10 days early planting on 27th October, Optimum planting time on 7th November, 10 days late planting on 17th November and 20 days late planting on 27th November and different mulching practices viz. Organic mulch (Paddy straw at 5 t/ha), Plastic mulch (Black colour) and Control (Without mulch) of potato. There were 15 treatments and each were replicated to four folds. These treatments were randomly arranged in each replication and divided into sixty plots. The results revealed that the significantly maximum number of haulms/hill at 45 DAP (4.50, 4.70 and 4.60), plant height (52.30, 54.00 and 53.10 cm), dry weight/ (27.90, 28.20 and 28.00) plant at 60 DAP, weight of tubers/plant (496.40, 504.10 and 500.30), weight of tubers/plant (>75 g) (207.70, 209.00 and 208.30) and tuber yield (369.30, 370.70 and 370.00 q/ha) were recorded under 20 Days Early Planting On 17th October among different planting dates during first, second year and mean data also. Whereas among the mulching practices significant variation were recorded among the all parameter. However maximum number of haulms/hill (3.60, 3.70 and 3.70) at 45 DAP, plant height (50.20, 52.0 and 51.10 cm), dry weight/plant (25.5, 25.9 and 25.7) at 60 DAP, weight of tubers/plant (454.80, 460.70 and 457.70), weight of tubers/plant (>75 g) (191.90, 193.30 and 192.60) and tuber yield (333.80, 334.90 and 334.30 q/ha) under the organic mulch (paddy straw at 5 t/ha) respectively, during first, second year as well as in mean data also.

“…This makes it quite evident that the power supply has not been disrupted. even when the load and output are exactly matched, network faults can still cause some transient signals to be transmitted [3]. For example, a short-term voltage drop in a power supply could indicate a system failure.…”

There are two techniques to ensure that renewable energy systems run continuously: on-grid and off-grid. In the first case the system can be managed in a network, in the second case it can be managed in a micro grid or island mode. Islanding means when a distributed generator (DG) keeps running even after there is no longer any external electricity. This situation can be dangerous for utility systems because it prevents equipment from connecting properly. Therefore, this paper proposes an active method for detecting island patterns at a given time. The use of DG installations such as photovoltaics can cause islanding detection issues. In addition, the number of DG sets in the power distribution system will affect the accuracy of island detection (ISD). On a test example DC power supply linked to a 415 V, 50 Hz network, the suggested solution was put into practice. In the MATLAB Simulink environment, the proposed method's efficacy was assessed. The proposed method is compared with existing active methods and shortens the detection time.

“…Isolation is a significant concern for utilities whose distribution systems, in part, are still active for DG. Effective techniques of identification categorize islanding episodes brought on by short circuits and other disruptions (such as load coupling) [2]. Except when they result in severe power quality issues [3] like overheating, islands are typically handled using passive technologies with huge dead bands [4]- [6].…”

Off-grid and On-grid are two technologies that allow renewable energy sources to run continuously. The system can be networked in the first scenario, and it can operate independently or as a microgrid in the second. The decentralised generator (DG) can run in island mode even if there isn't an external power supply accessible. This circumstance may prohibit the equipment from correctly joining, endangering the auxiliary system. In order to find island patterns at particular times, this research suggests a passive method. There may be problems with island detection (ID) when using DG systems like P.V. Additionally, the identification accuracy will be impacted by the quantity of DG devices in the power distribution system. The suggested remedy has really been put into practice in a test example involving a network-connected DC power source operating at 415 V and 50 Hz. The MATLAB Simulink environment was used to assess the method's efficacy. This technique speeds up detection and improves the THD.
