The results revealed that highest nitrogen, phosphorus and potassium uptake by African marigold in plots treated with irrigation at 1.0 Evapo-replenishment and fertigation with 100% recommended dose of fertilisers (RDF) and polyethylene mulching during both the seasons followed by 0.8 Evapo-replenishment and fertigation with 100% RDF and polyethylene mulching. Similar trend was observed in the uptake of micronutrients (iron, manganese, zinc and copper) as well. There was a decrease in uptake pattern of nutrients in case of rabi than kharif season. Among the treatments, the minimum nutrient uptake was recorded in 0.6 ER and soil application of normal fertilizers @ 100% RDF without Mulching.

Pulsing solution containing Sucrose (2%) + Al 2 (SO 4) 3 (1000 ppm) (9.89 days) resulted long vase life of foliage followed by solution containing Sucrose (2%) + BA (50 ppm) (9.10 days) in module VI. Whereas holding solution containing Sodium Benzoate (150 ppm) (9.10 days) showed long vase life of foliage followed by Sodium Benzoate (100ppm) (9.02 days) in module VI.

The experiment was conducted in 6 modules. The growth parameters like plant height (75.36 cm and 133.52 cm), plant spread E-W (46.41 cm and 74.09 cm), plant spread N-S (39.98 cm and 70.72 cm), stem diameter (15.97 cm and 32.94 cm), length of branch (31.68 cm and 58.34 cm), number of primary branches (19.61 and 31.42), number of secondary branches (17.29 and 36.73) were recorded highest and significant with the adoption of Module VI (Spacing-210cm X 210cm; Pit size-60 cm 3 ; FYM-25Kg/pit; Basal fertilizer dose-N:P 2 O 5 : K 2 O @ 40:40:40 g /plant; Fertilizer-19:19:19@ 0.2% and BAP-150 ppm) in two years respectively and internodal length (8.52 cm), number of tertiary branches (18.28), number of harvestable branches (63.41), foliage yield of plant (1.121 kg) also recorded highest in module-VI followed by Module-V. However, the yield per hectare (4.85 t/ha) was maximum in module-I because of maximum plant population.

Tomato is a warm season crop, it requires warm and cool climate. The plant is highly affected by adverse climatic conditions. The warm and cool climatic conditions provide an ideal condition for the development of many foliar, stem and soil-borne plant diseases. Fungal diseases are a major limiting factor for vegetable that cause serious yield reduction leading to severe economic losses. The major fungal diseases in tomato are seedling Damping off, septoria leaf spot, Eary blight, Late blight, Anthracnose, Powdery mildew, southern leaf blight, Fusarium wilt, Verticillium wilt, Buckeye rot. For each disease, main symptoms and their management practices mentioned. This review is based on combined information derived from available literature and expertise knowledge.

Being a vegetatively propagated crop it has limited availability of gene pool with low chances of flower breeding. This makes it an ideal target for gene transfer technologies that have the potential to hasten the production of new genotypes and broaden the available gene pool. Development of transgenics is the need in the modern era of plant breeding, as they possess the potential to incorporate those characters in crop varieties which are either difficult or impossible through conventional breeding approaches. It is the possible alternative way to varietal development and shortens the duration. Improved morphology, flower colour, resistance to diseases, pests, flower doubleness and fragrance are some of the desired novel traits in carnation where transgenic approaches need to intervene. Genetic modification by means of genetic engineering approaches made remarkable approaches in development of varieties.
