Implementing nutrient management strategies in soilless culture, which improve water use efficiency (WUE) and limit the loss of eutrophying elements without affecting crop performance, is a priority for the floriculture industry. The aim of the current research was to assess the effect of two nutrient management strategies, based on electrical conductivity (EC) or nitrate-nitrogen (N-NO3−) concentration control on plant growth, ornamental quality, plant–water relations, mineral composition, and WUE of greenhouse Hippeastrum grown in semiclosed soilless system. The recirculating nutrient solution was discharged whenever a threshold EC value of 3.0 dS·m−1 was reached (EC-based strategy), or when N-NO3− concentration decreased below the limit of 1.0 mol·m−3 (nitrate-based strategy). There were no significant differences in terms of plant growth parameters, stomatal resistance, leaf water relations, and macronutrient composition in plant tissues between the two nutrient management strategies. In the EC- and the nitrate-based strategies, the recirculating nutrient solution was flushed 10 and 5 times, respectively. The water loss (WL) and the total water use (Wuse) in the EC-based strategy were significantly higher by 261.1% and 61.5%, respectively, compared with the N-NO3−-based strategy. In contrast with the EC-based strategy, the adoption of the N-NO3−-based strategy significantly minimized the nitrate, phosphate, and potassium emissions to the environment. The effective WUE of the system (WUES) recorded in the N-NO3−-based strategy was higher by 55.9% compared with the one recorded with the EC-based strategy.

Sesame (Sesamum indicum L.) plays a vital role in the Indian agriculture, industry and export trade. It commonly known as til and also called as “queen of oilseeds” has been known to be one of the earliest domesticated edible oilseeds used by mankind. It is grown in wide range of environments extending from semi-arid tropics and subtropics to temperate regions. A field experiment entitled “effects of irrigation and nutrient management on summer sesame (Sesamum indicum L.)”,was conducted at the Agricultural Research Station, Brinjhagiri, Chatabar of Faculty of Agricultural Sciences, Siksha ‘O’ Anusandhan (Deemed to be University), Bhubaneswar (Odisha) during summer season of 2021. Treatments included three irrigation levels (I1: 2 irrigations at 21 and 63 days after sowing, I2: 2 irrigations at 21 and 42 days after sowingand I3: 3 irrigations at 21, 42 and 63 days after sowing) are treated in main plot and four nutrient management (N1: 100% RDF, N2: 100% RDF + 2 t/ha FYM, N3: 100% RDF + 2 t/ha FYM + Jeevamrut @250l/ha and N4: 75% RDF + 2 t/ha FYM + Jeevamrut @250l/ha) are treated in sub plot were experimented in split plot design replicate thrice. The experiment was conducted with the variety of TKG-21 followed the spacing of 30 cm × 10 cm. The experimental soil was sandy loam in texture with the pH of 5.65 and EC of 7.33 ds/m. The recommended dose of NPK was given 30:15:15 kg ha-1. From the experiment, highest seed yield (643.49 kg ha-1), haulm yield (1820.13 kg ha-1) and harvest index (26.04%) was obtained in I3. N4 (75% RDF + 2 t/ha FYM + Jeevamrut @250l/ha) showed second highest seed yield (652.21 kg ha-1), haulm yield (1882.07 kg ha-1) and harvest index (25.74%) which is at per with N3. Highest water use efficiency (2.72 kg ha-1 m-1) was calculated in I2N3. Hence, it can be conclude that cultivation of sesame under75% RDF + 2 t/ha FYM + Jeevamrut @250l/ha with 2 irrigations at 21 and 42 days after sowing proved better in terms of yield, economics and water use efficiency.
