“…The effect of mulch on plant height, stem diameter, internodes length, number of fruits/plant, weight of fruits/plant and fruit yield are found significantly higher in silver black plastic mulch as Table 2. Mulching has become an important practice in modern field production due to benefits such as increase in soil temperature [7,8] reduced weed pressure [9] moisture conservation [10], water saving and increase water use efficiency [11], reduction of certain insect pests [12] reducer soil erosion [13], higher crop yields [14] and more efficient use of soil nutrients. The stem diameter, plant height, internodes length, number of fruits/plant, weight of fruits/plant and fruit yield were recorded as 13.60 mm, 123.54 cm, 12.83 cm, 20.80, 216.68 gm and 10318.13 kg/ha respectively in silver black plastic mulch while it was found minimum in no mulch which was matched with [15,16,17].…”

Okra is a staple vegetable in Indian cuisine which is extensively cultivated year-round due to its rich composition of essential minerals, vitamins, carbohydrates, proteins and dietary fiber. The primary objective of this research was to investigate the impact of mulching and protective structures on okra cultivation during the winter period (off-season). Consequently, okra seeds were planted in three distinct environments: a Net-cum-poly house equipped with a ridge vent, Net-cum-poly house lacking a ridge vent and an open field. These environments were combined with three different mulch conditions: silver-black plastic mulch, black plastic mulch, and no-mulch. The experiment employed a two-factor large-plot design with four replications. The findings of this study revealed the substantial influence of mulching and protective structures on off-season okra cultivation. Key agronomic parameters, including stem diameter (17.20 mm), plant height (164 cm), internode length (18 cm), the number of fruits per plant (35), fruit weight per plant (367.31gm) and overall fruit yield (19755 kg/ha) exhibited statistically significant improvements in the combination of a Net-cum-poly house without a ridge vent and silver-black plastic mulch. In terms of water management, irrigation volumes delivered under mulched and non-mulched conditions were 387 mm and 446 mm respectively for the open field, while the corresponding figures for the protected environment were 319 mm and 366 mm. The highest water use efficiency was observed 61.97 kg/ha-mm in treatment combination with silver black plastic mulch and Net-cum-poly house without ridge vent. Notably, mulching resulted in a 13.34% reduction in water consumption compared to the non-mulched open field. In the protected environment, water savings reached 28.43% under mulch and 17.76% under no-mulch conditions relative to the non-mulched open field.

“…Remote sensing techniques offer several advantages, including the ability to monitor soil moisture over large and remote areas, provide regular and frequent data acquisition, and capture information at various spatial and temporal scales. These methods are especially valuable for applications such as precision agriculture, flood prediction, crop evapotranspiration and environmental management [14,15]. The integration of remote sensing data with Geographic Information Systems (GIS) allows researchers and decision-makers to analyze, visualize, and model soil moisture patterns in a geospatial context, providing valuable insights for a wide range of fields, from agriculture and water resource management to climate studies and disaster preparedness.…”

Soil moisture estimation is a critical component of environmental management and agricultural planning. This review paper explores an extensive array of techniques and methodologies for soil moisture estimation, with a focus on the integration of Geographic Information Systems (GIS) and remote sensing. The review encompasses a spectrum of approaches, ranging from ground-based methods involving in-situ measurements, gravimetric techniques, and electrical measurements to advanced remote sensing technologies such as passive and active microwave remote sensing, optical and thermal remote sensing, and GIS-based integration. The comprehensive analysis includes detailed case studies that demonstrate the practical applications of these methods in diverse geographical regions and environmental conditions. As the world faces increasing challenges related to climate change and water resource management, accurate soil moisture estimation emerges as a vital tool. This review paper not only offers insights into the methodologies but also addresses the challenges and limitations associated with soil moisture estimation. It provides a valuable resource for researchers, environmental scientists, and policymakers working in fields where soil moisture plays a pivotal role in decision-making and resource allocation. The integration of GIS and remote sensing techniques presents a powerful approach for addressing the global demand for precise and timely soil moisture information in a changing world.

“…A significant limiting factor in coverage of irrigation is the prevalent use Journal Home: www.biospub.com/index.php/resbio March, 2023 of flood irrigation, which has a low water use efficiency Prajapati and Subbaiah, 2015). Low crop productivity is caused by a number of negative variables, including insufficient groundwater reserves in terms of quantity and quality, excessive evaporative loss due to inadequate rainfall and increased pest and insect damage as a result of climate change (Prajapati and Subbaiah, 2019).…”

“…The gridded information on temperature is generally being used for various applications in agriculture (Parmar et al, 2019). To maximise yield per drop of water, it's crucial to control favourable soil moisture at the crop root zone and avoid soil losses (Prajapati and Subbaiah, 2018). In order to raise the standard of life for millions of people, particularly in rural regions, better planning, development and management of India's considerable assets, mainly its water and land resources, is urgently needed (Kumar et al, 2005).…”

Rain pipe irrigation has emerged as a promising solution for efficient water utilization and improved crop yields at a lower cost compared to traditional irrigation systems. An experiment was carried out to evaluate the hydraulic performance of rain pipes with different lengths (30 m and 45 m) and spacing (4 m and 5 m), operated at various pressures (1 kg cm -2 , 1.25 kg cm -2 and 1.50 kg cm -2 ) using a 7.5 hp pumping system. Key parameters such as distribution uniformity, uniformity coefficient, mean application rate and coefficient of variation were measured. The results indicated that the rain pipe system achieved optimal performance when operated at an operating pressure of 1.50 kg cm -2 , with a rain pipe length of 30 m and a spacing of 4 m. This configuration resulted in the highest uniformity coefficient (87.83%), distribution uniformity (76.29%) and mean application rate (6.81 cm h -1 ). Additionally, the maximum discharge per meter length of rain pipe and the maximum coverage width of one rain pipe were attained with a 30 m length operated at 1.5 kg cm -2 . These findings emphasize the effectiveness of rain pipe irrigation when employing an operating pressure of 1.5 kg cm -2 , a rain pipe length of 30 m and a spacing of 4 m. The study highlights the suitability of rain pipe irrigation as a cost-effective and efficient alternative for water management in Indian agriculture. By optimizing the operating pressure, rain pipe length and spacing, farmers can enhance water use efficiency and improve crop productivity, thereby contributing to sustainable agricultural practices in the face of limited water resources.
