Seaweed or Marine macro-algae are often regarded as an underutilized bioresource, many have been used as a source of food, raw materials for industry, and therapeutic and botanical purposes for decades. Moreover, several plant growth-stimulating compounds found in seaweed and products derived from seaweed have made them popular supplements to crop production systems. This article provides an in-depth analysis of how different seaweed species and seaweed products affect the plant growth and development of fruit crops. They also increase plants' biochemical components and can alleviate abiotic stress.

The present experiment was conducted during winter 2021-22 at Polytechnic in Horticulture, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Paria, Gujarat, India to study the effect of different type of mulches on soil properties and weed control efficiency in cauliflower var. Pusa Snowball K-1. The experiment was laid out in Randomized Block Design (RBD) with three replications and nine treatments viz., T1- Black polyethylene mulch, T2- Silver polyethylene mulch, T3- Red polyethylene mulch, T4- Silver black polyethylene mulch, T5- White polyethylene mulch, T6- Paddy straw mulch (10 t ha-1), T7- Sugarcane trash (10 t ha-1), T8- Farmer’s practice (Two hand weeding with flood irrigation) and T9- Control (No mulch). The study revealed that the black polyethylene mulch had a positive impact on soil properties and weed control efficiency in cauliflower var. Pusa Snowball K-1. Black polyethylene mulch (T1) recorded maximum soil temperature (32.70 °C, 32.33 °C, 29.86 °C, 27.93 °C, 27.73 °C, 31.70 °C and 33.93 °C) and soil moisture content (23.65 %, 22.60 %, 20.98 %, 22.26 %, 21.55 %, 20.65 % and 22.46 %) at 15, 30, 45, 60, 75, 90 and 105 DATP, respectively. The highest weed control efficiency (97.26 %) was also recorded by black polyethylene mulch (T1) among the all treatments.

Vegetables are potential source of vitamins, minerals and dietary fibers. Proper plant nutrition is essential for successful production of vegetable crops. Integrated supply of micronutrients with macronutrients in adequate amount is an important approach to sustain the soil health and crop productivity besides maintaining the nutritional quality of vegetables. Micronutrients (Fe, Zn, B, Cu, Mn, Cl, Mo, Ni) are required by plants in small or trace quantities. They are essentially as important as macronutrients for better growth, yield and quality of plants. Deficiencies of micronutrients may induce several physiological disorders in plants and drastically affect growth, metabolism and reproductive phase in plants. The successful tasks carried out by various micronutrients include plant metabolism, nutritional management, chlorophyll production, reproductive growth, flower retention, fruit and seed development, etc. Judicious use of micronutrients is essential for vegetable cultivation to get maximum yield of high quality produce. Foliar nutrition is the one of the most efficient method of applying micronutrients. Spraying of nutrient solutions on the foliage of growing plants is known as foliar nutrition.  Foliar nutrition of micronutrients at right concentration and at right growth stage is important for better results. Micronutrients applied by foliar application are more effective than those applied through soil application because soil application requires longer time for micronutrient absorption and assimilation. Foliar application of micronutrients plays a dynamic role and has been found beneficial for improving growth, yield and quality attributes of vegetable crops. In general, this review shows an immense potential of foliar nutrition of micronutrients in vegetable production. The main aim of this study is to know and explore the benefits of micronutrients through foliar nutrition for improving the production potential of different vegetable crops.

As a major commercial sector of agriculture, floriculture has emerged. One of the most often used types of jasmine that is grown commercially in India is Jasminum sambac. Time and rate of fertilizers applications can be a part of a successful, economical, and eco-friendly nutrient management plan. Given the aforementioned information, the current experiment was conducted with the aim of determining the impacts of split N, P, and K fertilizer application on the economics of jasmine (Jasminum sambac) production. The experiment was depicted under Randomized Block Designed with five replications and five treatments i.e. 50%N+100%P+100%K at last week of December and 50%N in last week of June (T1), 50%N+75%P+75%K in last week of December + 25%N+25%K in last week of March + 25%N+25%P in last week of June (T2), 50%N+50%P+50%K in last week of December + 25%N+25%P+25%K in last week of March + 25%N+25%P+25%K in last week of June (T3), 50%N+50%P+50%K in last week of December + 25%N in last week of March + 25%N+50%K+50%P in last week of June (T4) and 50%N+50%P+50%K in last week of December + 25%N+50%P+50%K in last week of March + 25%N in last week of June (T5) at Navsari Agricultural University, Gujarat, India on Jasminum sambac variety Baramasi during the year 2018-19. The highest net returns (Rs. 4,11,729/ha) and Benefit cost ratio (2.71) and were recorded with the application of (T3). The application of application of RDF (120:240:120 kg/ha) in three splits (application of 50%N+50%P+50%K in last week of December + 25%N+25%P+25%K in last week of March + 25%N+25%K+25%P in last week of June) increased yield with highest net return and BCR and therefore, was economically deduced best for the production of Jasminum sambac.
