Water pumping restrictions of high-quality irrigation water from underground aquifers is affecting vegetable production in Southwest Texas. There is a need to develop efficient deficit-irrigation strategies to minimize irrigation inputs and maintain crop profitability. Our objective was to determine how growth, yield, and quality of cantaloupe (Cucumis melo L. cv. `Caravelle') are affected by irrigation systems with varying input levels, including drip depth position and polyethylene mulch. Stand establishment systems used were containerized transplants and direct seeding. Field experiments were conducted on a Uvalde silty clay loam soil. Marketable yields increased in the order of pre-irrigation followed by: dry-land conditions, furrow/no-mulch, furrow/mulch, drip-surface (0 cm depth)/mulch, drip-subsurface (10-cm depth)/mulch, and drip-subsurface (30 cm depth)/mulch. Pooled across all drip depth treatments, plants on drip had higher water use efficiency than plants on furrow/no-mulch or furrow/mulch systems. Transplants with drip-surface produced 75% higher total and fruit size No. 9 yields than drip-subsurface (10- or 30-cm depth) during the first harvest, but total yields were unaffected by drip tape position. About similar trends were measured in a subsequent study except for a significant irrigation system (stand establishment interaction for yield. Total yields were highest for transplants on drip-subsurface (10-cm depth) and direct seeded plants on drip-subsurface (10 and 30 cm depth) with mulch.

Для обеспечения населения РФ качественной, полезной и экологически безопасной овощной продукцией в требуемом количестве необходимо изучение потенциальной продуктивности новых сортов и гибридов овощных культур, применение современных элементов технологии и продуктов в области агротехнологий выращивания. Хороший вкус, высокое содержание ценных для человека витаминов, микроэлементов и органических кислот вывело сладкий перец в ранг наиболее популярных овощных культур. В мире выведено и культивируется огромное количество сортов сладкого перца. В нашей стране наиболее распространенным сортотипом является перец сладкий (Capsicum annuum), или болгарский. На обыкновенных черноземах Бирючекутской селекционной опытной станции (Новочеркасский район Ростовской области), имеющих слабощелочную реакцию среды, мощный гумусовый горизонт, среднюю обеспеченность подвижным фосфором и высокую обменным калием, в 2017–2018 годах была исследована потенциальная продуктивность перца сладкого гибрида Темп при высоком уровне обеспеченности растений влагой и питательными элементами. Оценено комплексное действие основного внесения расчетных доз минеральных удобрений, капельного орошения, трехкратной подкормки водорастворимыми удобрениями «Мастер» и органоминеральным наноудобрением «Арксойл» на урожайность и качество перца сладкого. Выяснено, что основное удобрение и подкормки влияют, в первую очередь, на число плодов на одном растении, увеличивая их в 2–3,3 раза при незначительном повышении массы плода. Установлено, что без применения минеральных удобрений при капельном поливе было получено 25–27 т/га плодов. Использование рекомендованной дозы удобрений N120P120K120 увеличило урожайность перца до 50,5 т/га, а комплексное применение основного удобрения с 3-кратной корневой подкормкой водорастворимым удобрением «Мастер» позволило получить урожайность перца до 64,8 т/га. Наиболее высокая продуктивность растений была получена при комплексном использовании расчетной дозы на урожайность 90 т/га в сочетании с корневой подкормкой – 86,8 т/га при хорошем качестве плодов перца. To provide the population of the Russian Federation with high-quality, healthy and environmentally friendly vegetable products in the required amount, it is necessary to study the potential productivity of new varieties and hybrids of vegetable crops, use modern elements of technology and products in the field of agricultural technologies. Good taste, high content of vitamins, microelements and organic acids valuable for humans have made sweet peppers one of the most popular vegetable crops. A huge number of varieties of sweet peppers have been bred and cultivated in the world. In our country, the most common cultivar type is bell pepper (Capsicum annuum) or Bulgarian. On ordinary chernozems of the Biryuchekutskaya selection experimental station (Novocherkassk district of the Rostov region), which have a weakly alkaline reaction of the environment, a powerful humus horizon, an average supply of mobile phosphorus and high exchangeable potassium, in 2017-2018, the potential productivity of sweet pepper the level of supply of plants with moisture and nutrients. The complex effect of the main application of the calculated doses of mineral fertilizers, drip irrigation, 3-fold top dressing with water-soluble fertilizers Master and organomineral nanofertilizers Arxoil on the yield and quality of bell peppers was evaluated. It was found that the main fertilization and feeding affect, first of all, the number of fruits per 1 plant, increasing them by 2-3.3 times with a slight increase in the weight of the fruit. It was found that without the use of mineral fertilizers with drip irrigation, 25-27 t/ha of fruits were obtained. The use of the recommended dose of fertilizers N120P120K120increased the yield of pepper to 50.5 t/ha, and the complex application of the main fertilizer with 3-fold root feeding with the water-soluble fertilizer Master allowed to obtain the yield of pepper up to 64.8 t/ha. The highest plant productivity was obtained with the integrated use of a calculated dose for a yield of 90 t / ha in combination with root feeding - 86.8 t/ha with good quality pepper fruits.

In the Caborca area, water scarcity is the main problem for the farmers, because of the depletion of the aquifer. This is the main reason why they are focusing on orchards and vegetables. Melon is the vegetable annual crop more extensively grown in this area and is furrow-irrigated with 120 cm of water. But, because of the scarcity of water, it is necessary to use drip irrigation. The objective of this study was to validate in a commercial field (15 ha) the effects of drip irrigation system on the water use, yield, and quality of two honeydew melon varieties (green flesh and orange flesh) in the Caborca area. Our results indicate that, with 50 cm of water applied, yields were 2146 to 2802 boxes/ha for green flesh and orange flesh, respectively. The predominant sizes were 4s and 5s with 25% and 38% for green flesh, and 5s and 6s with 42% and 36% for orange flesh. These sizes are the best for the exportation market.

Agriculture is one of the primary sectors in the Indian economy. Over the past several years, agricultural scientific techniques and agricultural implements have developed in the region, replacing the traditional method of farming. By which the economic condition of the farmers has improved. In addition, there are still some small farmers in India who use the old traditional methods of farming of agriculture because they do not have the resources to use modern methods. Besides, it is the only region that has contributed not only to the development of itself but also to other areas of the country. Agriculture has a major contribution to the country’s GDP and national income. In addition, it requires a huge manpower and labour which constitutes about 80% of the total workforce. Employees work not only directly but indirectly in the agricultural sector. Irrigation is the use of controlled amounts of water at the required intervals to the plants. Effective irrigation will affect seed development, germination, root growth, utilization of nutrients, plant growth and revival, yield and quality of the entire development process. The farmer knows how much water he has to give to the crop and when crop is to be planted, but the best system of irrigation it is necessary to have the information about use of equipment, plant species, soil structure, soil preparation and It is also important to be aware of all these that at what stage to watering the plant. The aim of this research paper is to describe how the Internet of Things (IoT) framework plays an important role in the field of agriculture. Here to show the importance of IoT in agriculture, we choose “Smart Drip Irrigation System.”
