“…A moderate water stress and limited nitrogen supplies promote the growth and development of fruit and result in a favorable increase of chlorophyll in the leaves, which in turn is responsible for an increase in DM. These results are in accordance with previously recorded observations [ 11 , 23 , 33 ]. Under the test conditions, the optimized water and nitrogen levels avoid excessive water and fertilizer use, while supporting proper growth and development.…”

“…The availability of nitrogen is an important determinant of crop yield and quality, by directly affecting photosynthesis and the accumulation, transfer, and distribution of biomass [ 10 ]. Previously, the studies of water-fertilizer management mainly focused on irrigation methods [ 11 ], irrigation amount and frequency [ 12 ], and various types of fertilizers [ 13 – 15 ].…”

“…Compared to classical fertigation, this new technique significantly increases yield, water use efficiency (WUE), and nutrient use efficiency [ 16 – 22 ]. For instance, compared to conventional furrow irrigation, properly controlled fertigation increases the yield of C. annuum and enhances WUE [ 11 , 23 ]. It was experimentally shown that carefully determined fertilizer quantities could ensure high yield of C. annuum , at the same time reducing production costs [ 13 ].…”

This study investigated the effects of different combinations of irrigation and nitrogen levels on the growth of greenhouse sweet peppers, assessing yield, quality, water use efficiency (WUE), and partial factor productivity from applied N (PFPN). By using controlled drip irrigation, the optimal conditions for efficient, large-scale, high-yield, and high quality production of sweet peppers in Northwest China were determined. Using the local conventional irrigation and nitrogen regime as a control (105% ET0, N: 300 kg·hm−2), three alternative irrigation levels were also tested, at 90%, 75%, and 60% ET0. These were combined with nitrogen levels at 100%, as the control, and 75%, 50%, and 25%, resulting in 16 combination treatments. The results show that different supplies of water and nitrogen nutrition had a significant impact on the growth, yield, WUE, PFPN, and quality of fruit. The treatments of W0.90N0.75, W0.90N0.50, W0.75N0.75, and W0.75N0.50 can better maintain the “source-sink” relationship of peppers. They increased the economic yield, WUE, and PFPN. A principal component analysis was performed to evaluate indicators of fruit quality, revealing that the treatment of W0.75N0.50 resulted in the best fruit quality. For greenhouse sweet peppers produced in Northwest China, the combination of W0.90N0.75 resulted in the highest economic yield of 34.85 kg·hm−2. The combination of W0.75N0.75 had the highest WUE of 16.50 kg·m−3. The W0.75N0.50 combination treatment had the highest fruit quality score. For sustainable ecological development and in view of limited water resources in the area, we recommend the W0.75N0.50 combination treatment, since it could obtain the optimal fruit quality, while its economic yield and WUE were 9% and 4% less than the maximum, respectively. This study provides a theoretical basis for the optimal management of water and nitrogen during production of greenhouse sweet peppers in Northwest China.

“…The results obtained in this study demonstrate that the effects of quality of irrigation water and irrigation frequency are significantly important in order to obtain higher yield. This is in line with the findings by Koksal Aydinsakir et al, (2011) in carnation, Bagali et al, (2012) in onions; Lodhi et al, (2014) Ayyanna et al, (2014) in marigold; Puneet Sharma and Arun Kaushal (2015); Ughade and Mahadkar (2015) in brinjal and Muthu Kumar and Ponnuswami (2013) in noni. Nutrients like N, P and K are being the constituent of proteins, amino acids, nucleic acid, various enzymes and coenzymes is associated with the increased shoot length and leaf area resulting in more photosynthesis and thus increased transformation of manufactured food material from source (leaf) to sink (flower bud) as reported by Vinoth (2012) in lilium hybrids; Khalid Elhindi et al, (2015) in Zinnia and Jakadeeshkanth, (2014) in curry leaf.…”

The influence of different deficit irrigations on capsicum crop biometric parameters and fruit yield were assessed in an experiment the variety ‘Indra’ was tested using completely randomized block design with three deficit irrigations (0.50, 0.75 and 1.0 ETC) and 5 replications in polyhouse and 1.0 ETC in open field conditions. The biometric parameters namely plant height, number of leaves, number of branches, number of days to flowering; number of days to harvesting, number of fruits per plant, individual fruit weight and fruit yield are measured. From the results, observed that, average of plant height (91.23 cm), number of leaves (91.3), number of branches (6.9), number of days to flowering (32.7), number of days to harvest (71), fruit number per plant (7), individual fruit weight (75.99 g) and yield (6466.66 t ha-1) parameters found higher in 1.0 ETC (T1), but in case of water productivity (12.4 kg ha-1 mm-1) in the treatment (T2) 0.75 ETC showed superiority. From the results, it is determined that by adopting the 0.75 ETC (T2) we can save the water up to 25%. Aims: The objective of this study is to evaluate the influence of deficit irrigation in biometric parameters of capsicum. Study Design: Completely randomized block design. Place and Duration of Study: Experiment conducted during January to May 2018 at Agriculture farm, College of Agricultural Engineering, Madakasira located in Rayalaseema region. Methodology: Physical and chemical properties of field were found by using standard methods. The experiment was arranged using CRD design with three levels of irrigation and five replications. Fertigation was done with 250:150:150 kg/ha recommended doses of N:P:K to capsicum crop. Based on climatological approach (evapotranspiration basis) the quantity of water applied. All the recommended cultural practices selection of cultivars, nursery raising, land preparation, laying drip lines, fumigation, fertilizer application, transplanting, pruning, training and plant protection measures are removing affected plant parts, flowers, fruits and for thrips and aphids management are dicofol (2 ml/L) and imidacloprid (0.5 ml/l) standardized for polyhouse were followed time to time to ensure a healthy crop stand. Crop water requirement was determined by using AquaCrop model. The parameters viz., plant height, number of leaves per plant and number of branches per plant were recorded at 30, 60, 90, 120 days after transplanting and at harvest. The collected data of different parameters during the course of research were analysed as per the completely randomized design (CRD) by applying the technique of analysis of variance procedure. Results: Among all the treatments, Irrigation with 100% Crop Evapotranspiration (1.0 ETc) (T1) registered the highest plant height, number of leaves, number of branches, number of days required to harvesting, number of days required to flowering, fruit number, average fruit weight and fruit yield, followed by 0.75 ETc (T2), 0.5 ETc (T3) and open field conditions. This might be due to good soil moisture distribution in drip irrigation compared to the open field. From the observed parameters it is exhibited that drip irrigation 0.75 ETC recorded as the higher water productivity (12.4 kg ha-1 mm-1) followed by drip irrigation scheduled at 1.0 ETC (11.49 kg ha-1 mm-1), 0.5 ETC (11.07 kg ha-1 mm-1) and open field (1.38 kg ha-1 mm-1) recorded very less. Conclusion: By adopting T2 (0.75 ETC) irrigation treatment we can save the water up to 25%, by using saved water additional quantity of vegetables can be produced.
