The effect of irrigation and bio-stimulant (ComCat) applications on fruit quality parameters at the ‘Rubygem’ strawberry variety was investigated. The amounts of irrigation water applied were 0.50, 0.75, 1.00 and 1.25 times of water surface evaporation measured Class A pan placed over the crop canopy and the corresponding regimes were denoted as IR50, IR75, IR100 and IR125. Furthermore, bio-stimulant is applied four times with three weeks interval, approximately two months after planting. Applications of bio-stimulant were not efficient on examined parameters. Decreasing of the irrigation levels were significantly increased TSS and sugar/acid ratio which affects the fruit taste. The highest TSS and sugar/acid ratio was determined at IR50 plot with 9.42% and 21.7 values, respectively. However, fruit weight was significantly decreased except of IR100 plot. Moreover, deficient irrigation (IR50 and IR75) may cause a decrease at fruit weight. Recently, it could be crucial strategy to improve sugar and sugar/acid ratio which were prominent for consumers on the eating quality. Also, improving fruit taste with bio-stimulant application at optimum irrigation level (IR100) without any decreasing of fruit weight was determined.

This study aimed to evaluate the influence of different levels of irrigation on the quality parameters involved in the dried-bananas production from 3 different cultivars. The experimental design was a completely randomized factorial 3 x 3, with three genotypes of bananas (Prata-Anã, FHIA-18 and BRS Platina) produced in the semi-arid region of Minas Gerais.) and three irrigation levels (50, 75 and 100% of crop evapotranspiration - ETC), with three replications. For the processing purpose, the fruits were selected at the maturity stage 6. Then they sanitized in hypochlorite of sodium solution at 100 mg L-1, peeled and dehydrated through the drying convective method with hot air, in dryer with forced air, in dryer with forced air circulation at 65ºC for 24 hours. The dried bananas were evaluated according to the following physical and chemical aspects: moisture, length, diameter, firmness, color (brightness, chroma and ºHue), soluble solids and titratable acidity, and sensory characteristics: purchase intention and acceptance. The humidity, length, diameter, firmness, color and acidity of dried bananas were influenced by the different studied irrigation levels. In the sensory evaluation, the best result regarding appearance, color, texture and flavor requirements was observed in banana processed from 'Prata-Anã' irrigated with the total level of water (100%). The dried banana processed from 'BRS Platina' was the least accepted in the sensory tests.

Abstract Peanut quality parameters were analyzed across four irrigation levels during the 2002 through 2007 crop years. The peanut quality parameters consisted of total sound mature kernels and sound splits (farmer stock grade), shelling outturn by commercial edible size, accept and reject kernels by commercial edible size, seed germination, and aflatoxin. The four irrigation levels consisted of a full level (100%), two reduced levels (66% and 33%), and a non-irrigated control. The research was conducted at the USDA/ARS National Peanut Research Laboratory's Multi-crop Irrigation Research Farm in Shellman, Georgia. By year, significant differences in the irrigation treatments depended upon precipitation distribution for the specific quality parameters. For the average over the six years in the study, farmer stock grade was not significantly different in the 100, 66, and 33% treatments while all were significantly higher than the non-irrigated control. Total shelling outturn and total edible outturn were higher in the 100 and 66% compared to the 33% and non-irrigated treatments. Total reject outturn and total oil stock were not significantly different in the 100, 66, and 33% treatments, while all were significantly lower than the non-irrigated control. Percent seed germination did not differ across treatments. Aflatoxin in total reject outturn and total oil stock was significantly higher for the non-irrigated treatment compared to the irrigated treatments.

Fertigation was found technically and economically feasible for tomato cultivation in winter as well as in summer. An experiment was conducted with summer tomato (BARI Hybrid Tomato–4) having 2 drip irrigation levels with different levels of NPK and micronutrient (B, Zn, and Mg) during kharif-1 seasons of 2007 and 2008. The fertilizer levels were N100 P55 K120 kg/ha, N100 P55 K120 B1 Zn4 Mg4 kg/ha, N100 P70 K140 kg/ha and N100 P70 K140 B2 Zn6 Mg8 kg/ha and the irrigation levels were drip irrigation at 2 days interval and drip irrigation at 3 days interval. The highest marketable yield of summer tomato (35.90 t/ha and 27.12 t/ha) were obtained from the fertigation treatment with fertilizer doses of N100 P55 K120 B1 Zn4 Mg4 kg/ha irrigated at 2 days interval in 2007 and 2008. The cull yield was also the lowest (2.53 t/ha and 1.15 t/ha) in this treatment in both the years. The lowest tomato yield (20.50 t/ha and 18.29 t/ha) were obtained from the treatment with fertilizer doses N100 P70 K140 kg/ha irrigated at 2 days interval where no micronutrients were used. Fruit quality parameters like TSS, Vitamin-C and ?-carotene were also the highest for the best yielder. So, use of micronutrients with NPK showed a significant effect on quality fruits as well as yield of summer tomato. The best yielder treatment received 261.0 mm of seasonal water including an effective rainfall of 60.5 mm during the crop seasons. The highest BCR (4.41) was also found in the same treatment.

The current study was carried out at the experimental farm of Rana Sugars Ltd., Buttar Seviyan, Amritsar, Punjab, India, to identify methods to improve the yield and quality of ratoon sugarcane in potassium-deficient soils. The treatments comprised two levels of irrigation, resulting in plants which either received sufficient water (I1) or were water-stressed (I2), and four rates of potassium (K) application: 0 (K1), 40 (K2), 80 (K3) and 120 (K4) kg K2O ha−1. The results showed that the irrigation levels did not influence crop parameters significantly, although all parameters presented higher values for I1-treated plots. Compared to the K1 (i.e., 0 kg ha−1 K fertiliser applied) treatment, the K2, K3 and K4 treatments yielded 11.16, 37.9 and 40.7%, respectively, higher millable canes and 1.25, 5.62 and 13.13% more nodes per plant, respectively. At 280 days after harvest of the first (plant) crop, the I1 treatment provided ratoons which were up to 15.58% higher than those obtained with the I2 treatment, with cane girths up to 7.69% wider and yields up to 7.29% higher than those observed with the I2 treatment. While the number of nodes per plant did not differ significantly between treatments, there were significant differences in other parameters. Quality parameters (with the exception of extraction percentage) were significantly enhanced by the K3 treatment. The benefit-to-cost ratio (B/C) was higher for the I1 treatment than for the I2, due to a reduced productivity associated with the I2 treatment. At both irrigation levels, the K3 treatment resulted in the highest quality parameters. K1-, K2- and K4-treated plots presented more instances of insect infestations than plots receiving the K3 treatment. Relative to the K3 plots, infestation by the early shoot borer (Chilo infuscatellus) was 18.2, 6.0 and 12.2% higher, respectively, in plots that underwent the K1, K2 and K4 treatments, while infestation by the top borer (Scirpophaga excerptalis) was 21.2, 9.21 and 14.0% higher, and that by the stalk borer (Chilo auricilius) was 10.7, 0 and 8.10% higher. Not all infestation differences between treatments were significant. Our research demonstrates that growing sugarcane in potassium-deficient soils with applications of 80 kg K2O ha−1 under irrigation should be recommended to increase yield and quality while minimising insect infestation and to implement sustainable ratoon sugarcane production.

An experiment was conducted to study the effect of crop geometry and irrigation levels on sugarcane under drip irrigation at Main Sugarcane Research Station, Junagadh Agricultural University, Kodinar during 2011-14. The treatment consisted of three crop geometry (90 cm normal planting, paired row planting (60: 90 cm) and paired row planting (60: 120 cm) and three drip irrigation levels (0.5 PEF, 0.7 PEF and 0.9 PEF) and with an extra treatment (control) having surface irrigation (90 cm) at 1.0 IW/CPE ratio. Experimental results indicated that paired row (60: 90 cm) planting gave significantly higher cane yield (101.04 t/ha) over 60: 120 cm paired row planting (88.82 t/ha) and remained at par with 90 cm row spacing (97.34 t/ha). Drip irrigation level of 0.9 PEF gave significantly higher cane yield (108.63 t/ha) over 0.7 PEF (96.01 t/ha) and 0.5 PEF (82.56 t/ha). Juice quality parameters like brix, sucrose, purity and sugar recovery percent were not affected significantly due to either crop geometry or different drip irrigation levels. Significantly higher cane yield was recorded under drip irrigation (95.74 t/ha) compared to surface irrigation (76.86 t/ha). The total water use was not affected due to different crop geometries. Water use decreased constantly in 0.7 and 0.5 PEF compared to 0.9 PEF and accordingly WUE increased.

The effect of irrigation regimes (irrigation at 1, 3 and 5 days interval) on four rice hybrids (6129 Gold, 6444 Gold, Tej Gold and DRH 775) was studied in split plot design during dry (boro) season of 2017 at Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal. Mean cultivar days to 50% flowering and maturity of hybrid rice were 99.1 and 125.9 days, respectively; while total summed GDD, HTU and PTU for entire life cycle were 1656°C day, 10410°C hour and 20311°C hour, respectively. Irrigation at 1 day interval resulted in highest grain yield (5.92 t ha-1), heat use efficiency (3.62 kg ha-1 °C day-1) and head rice recovery (58.2%), but lowest (3.08 kg ha-1 mm-1) water use efficiency (WUE). Among four hybrids, 6129 Gold yielded highest (5.88 t ha-1) with maximum WUE (4.44 kg ha-1 mm-1) and high-intermediate gelatinization temperature (score 3.0), that yield was 0.31, 0.42 and 0.51 t ha-1 greater over Tej Gold, DRH 775 and 6444 Gold, respectively. Irrigation regime could influence a few grain quality parameters viz. brown rice (73.8-75.6%), head rice recovery (53.3-58.2%) and alkali spreading score (score 3.2-4.1) in the investigation. Irrigation at 3 days interval might be adopted due to better WUE (5.02 kg ha-1 mm-1) with moderate grain yield (5.80 t ha-1) during boro season in lower gangetic plains of West Bengal.

São escassas as informações na literatura acerca das respostas da abóbora ao manejo da irrigação associada a adubação nitrogenada. Objetivou-se neste trabalho avaliar o desempenho produtivo (número, massa fresca, massa seca e produtividade) e os parâmetros de qualidade (diâmetro, comprimento, espessura da polpa e °Brix dos frutos) da cultura da abóbora sob lâminas de irrigação associadas a doses de adubo nitrogenado. Adotou-se o delineamento de blocos casualizados em parcelas subdivididas, onde nas parcelas estavam inseridas o fator doses de nitrogênio (50; 70; 100; 125% kg de N ha-1) e nas subparcelas as lâminas de irrigação (50; 75; 100; 125% da evaporação medida no tanque classe A - ‘ECA’) com quatro repetições. A pesquisa foi conduzida em campo na área experimental da Estação Meteorológica pertencente a Universidade Federal do Ceará. A produtividade máxima alcançada foi de 4269,6 kg ha-1 obtido com a combinação da lâmina de água de 444,10 mm (122,5% da ECA) e do nível de nitrogênio de 33,65 kg ha-1 de N (112,16 % do recomendado de N).   Palavras-chave: jerimum de leite, adubação, manejo da irrigação.     BEZERRA, R.

PRODUCTION AND QUALITY OF MARANHÃO PUMPKIN UNDER INFLUENCE OF WATER DEPTHS AND NITROGEN DOSES     2 ABSTRACT   The pumpkin crop is becoming outstanding in  the world scenario due to growing concern with the issue of food challenge and its production characteristic associated with small properties. There is little information in the literature about pumpkin responses to irrigation management associated with nitrogen fertilization. The objective of this work was to evaluate productive performance (number, fresh weight, dry weight and productivity) and quality parameters (diameter, length, pulp thickness and ° Brix of the fruits) of pumpkin culture under irrigation levels associated with doses of nitrogen fertilizer. A randomized complete block design was used in subdivided plots, where the nitrogen dose factor (50; 70; 100; 125% kg of N ha-1) was inserted in the plots and in the subplots, irrigation depths  (50; 75; 100; 125% of evaporation measured in tank class A - 'ECA') with four replicates. The research was conducted in the experimental area of the Meteorological Station belonging to the Federal University of Ceará. The maximum productivity reached was 4269.6 kg ha-1 obtained with the combination of water blade of 444.10 mm (122.5% of ECA) and nitrogen level of 33.65 kg ha-1 of N (112.16% of the recommended N).   Keywords: milk jerimum, fertilization, irrigation management.
