RESUMO
The implementation of integrated potassium management presents a viable approach for augmenting plant growth, yield, and nutrient uptake while enhancing soil nutrient availability. A field experiment was executed during the rabi season of 2020, employing a randomized complete block design encompassing eight treatments involving standard (100%) and reduced (75% and 50%) rates of the recommended dose of potassium (RDK) administered through muriate of potash (MOP). Treatments included variations in the incorporation/exclusion of plant growth-promoting rhizobacteria (PGPR), farmyard manure (FYM) at 25% of potassium recommendation, and foliar application of nano potash. The use of 100% RDK +25% K augmentation through FYM + PGPR and nano K fertilizer spray at 25 and 40 DAS (T8) exhibited significant enhancements in green fodder yield (64.0 ± 2.2 t ha-1) over control with no potassium application (47.3 ± 3.7 t ha-1) and found at par with and 75% RDK + 25% K augmentation through FYM + PGPR and nano K fertilizer spray at 25 and 40 DAS (T7). These treatments yielded maximum percent increase for plant height (34.9%), leaf count (38.5%), leaf dimensions (28.8-31.5%), stem girth (25.84%), root volume (27.0%), and root length (37.64%), observed at the harvest stage compared to control (T1-no potassium application). The treatment T8 was on par with T7 and recorded highest uptake of macro (N, P, and K) and micro (Zn, Fe, Cu, and Mn) nutrients. While soil parameters such as available nitrogen and potassium levels were notably increased through the application of treatment T7 across various treatment combinations and found significantly superiority over treatment T8. Multivariate analysis also highlighted treatment T7 is more efficient in maintaining sustainability. Hence, based on the present findings it can be concluded that application of 75% RDK +25% K augmentation through FYM + PGPR and nano K fertilizer spray at 25 and 40 DAS (T7) can be recommended for achieving enhanced productivity and soil fertility improvement within agricultural systems.
RESUMO
Background Ventral hernias are the second most common type of hernias accounting for 21-35% of all hernia types. Ventral hernia includes incisional, umbilical, epigastric, and Spigelian hernias, among others. Currently, patients and surgeons prefer laparoscopic repair of ventral hernias. This study aimed to compare laparoscopic with open hernia repair in terms of various operative and patient parameters. Methodology This was a prospective observational study conducted in the Department of General Surgery, Dr. Sampurnanand Medical College, Jodhpur. All patients admitted with a diagnosis of ventral hernia for mesh repair (open as well as laparoscopic) were included. Laparoscopic and open hernia repair were compared in terms of operative time, postoperative hospital stay, time to resume routine activity, postoperative complications, and recurrence. Results Among the 50 patients included in the study (25 patients each in the laparoscopic and open groups), the mean operative time was 57.52 ± 5.80 minutes in the laparoscopic group and 59.8 ± 11.15 minutes in the open group. The mean hospital stay in the laparoscopy and open groups was 7.4 ± 1.58 days and 9.88 ± 2.96 days, respectively (p-value = 0.0006; significant). Postoperative pain (using the visual analog scale score) was less in patients who underwent laparoscopic surgery (p-value = 0.001; significant). Seroma and surgical site infections were the most common complications which were observed more in the open hernia repair group. Recurrence was seen in one case operated by the open technique. Conclusions Laparoscopic ventral hernia repair is technically safer, effective, and feasible with better clinical outcomes in patients seeking treatment in a government hospital.
RESUMO
The population is increasing rapidly and the demand for water by cities, industries and agriculture has tended to grow even faster than the population. Wastewater reclamation consists of a combination of conventional and advanced treatment processes employed to return a wastewater to nearly original quality, reclaiming the water. The environmental health aspects associated with reclamation of wastewater include quality aspects and public health aspects. An attempt has been made in the present paper to describe these aspects and to suggest appropriate solutions.
