Watermelon is grown under a range of moisture regimes from rainfed to heavily irrigated, but water requirement patterns are not well documented. Drip irrigation and plastic mulch provide the opportunity to control water applications to optimize yield and quality. Water applied through subsurface drip irrigation was measured in two watermelon trials in 1998 (25 seeded and 20 seedless cultivars) and 1999 (26 seeded and 14 seedless cultivars) at Lubbock, Texas. Melons were transplanted in plastic-covered raised beds 13.6 m long spaced 2 m apart. Irrigation was applied when morning soil moisture tension measured by tensiometers exceeded 20 kPa. Watermelon yields ranged from 50 to 100 t·ha-1 with excellent quality. Weekly water use averaged 14 mm during the first 3 weeks of establishment then increased to 28 mm during the next 3 weeks as plants were running and blooming. During the 5-week fruit-enlargement period, water uptake averaged 57 mm, then decreased as full fruit size was attained. Similar uptake patterns in both years suggest that meaningful crop coefficients for scheduling watermelon irrigation could be based on phenological growth stages.

A study was conducted to assess the effect of drip irrigation and plastic mulch on growth and seed yield of Semialata. Two types of plastic mulch (green and silver/black) were tested at three levels of irrigation (120%, 100% and 80%) by drip irrigation and one level (100%) by furrow irrigation. The daily water requirement of Semialata was estimated by the equation ETcrop= ETox crop factor. ETcrop is crop water requirement mm/day. ETo (reference evapotranspiration, mm/day) was calculated by FAO calculator which uses temperature and humidity data. In this experiments there were twelve treatments were considered. The treatments were replicated thrice. The experiment was laid in randomized block design. It was observed that drip irrigation with or without plastic mulch is yielding better results in terms of growth parameters and seed yield as compared to furrow irrigation without plastic mulch. It was also observed that maximum suppression (67.58%) of weeds resulted with drip irrigation and silver/black plastic mulch at 80% level of irrigation.

The investigation was carried out to evaluate the effect of different organic manures on turmeric with reference to vegetative growth, biomass production, rhizome yield and its attributes of turmeric (Curcuma longa L.). Turmeric showed better response to the application of organic manures. Plant with neem cake application had the taller plant (79.30 cm), maximum number of tillers per plant (5.40), leaf number (5.40), leaf area (44.09) leaf area index (0.429), fresh weight of halum ( 190.05g), fresh weight of root (49.13 g), fresh weight of rhizome per plant (256.21 g) and dry weight of halum (15.21g), dry weight of root (7.32 g), dry weight of rhizome per plant (40.35 g), total dry matter yield (6.85 t ha-1) than those received other types of manures. Moreover, yield attributes such as number of mother rhizomes per plant-1 (1.75), more number of primary rhizomes per plant-1 (5.19), secondary rhizomes per plant-1 (18.03) and tertiary rhizomes per plant (7.69) were also highly accelerated by neem cake application. Similarly, the same treatment expressed the best in terms of size of mother rhizome (7.69 cm), primary rhizome (21.86 cm) and secondary rhizomes (7.05 cm).All these parameters in cumulative contributed to  produce the highest estimated fresh rhizomes yield & cured rhizomes yield (29.48 t ha-1, 5.59 t ha-1 respectively). The highest curing percentage (20.28) was observed in T3 treatment having mustard cake@ 2.0 t/ha. Thus, organic manure like neem cake was best fitted natural fertilizer for turmeric cultivation.DOI: http://dx.doi.org/10.3329/agric.v10i1.11060The Agriculturists 2012; 10(1): 16-22

HighlightsRegulated deficit irrigation and fertilization ratio were used to test grapes in extremely arid areas.Physiology, yield, and quality indexes of drip irrigation grapes were analyzed accordingly in this study.Single and comprehensive evaluation models were used to evaluate the optimal water and fertilizer treatment.Abstract. Water shortage and chemical fertilizer abuse are important factors restricting grape industry development in Xinjiang. In this study, the physiology, yield and quality indexes of drip irrigation grapes were analyzed, and the water-fertilizer system was properly optimized by a model of combination of single evaluation methods and comprehensive evaluation methods. Five irrigation schemes and three fertilizer ratios were combined to form 15 treatments in Xinjiang, China. Results showed that irrigation and fertilization had different effects on physiology, yield, and quality indicators of grapes in different growth periods, and each index cannot reach its maximum value under the same treatment. Four single evaluation methods of Principal Component Analysis (PCA), Membership Function Analysis (MFA), Gray Correlation Analysis (GCA), and TOPSIS were used to evaluate grapes of 15 water and fertilizer treatments, but there were 9 treatments with a ranking standard deviation greater than 1.0, which was over 60% of all treatments. Through four comprehensive evaluation methods of Average Value, Borda, Copeland, and Fuzzy Borda, single evaluation results were analyzed, and the standard deviations of 13 treatments ranked 1.0 or below, more than 80% of all treatments, and Average Value comprehensive method had the highest compatibility. Therefore, the combination of Average Value method and four single evaluation methods is an appropriate evaluation model. It was determined that W4F2 was the optimal treatment which was performed regulated deficit irrigation in the berry mature period, the irrigation amount, nitrogen, phosphorus, and potassium fertilizers were sequentially controlled to 694 mm, 235.7, 235.7, and 353.6 kg·ha-1, and its ranking was ranked first under the four comprehensive evaluation methods. This study can provide theoretical guidance for the combined evaluation of water and fertilizer use of drip irrigation grapes in extremely arid regions.

ABSTRACT The present study aimed to evaluate the development, yield and quality of four sugarcane cultivars fertigated by subsurface drip system. The experiment was carried out in Campinas-SP, Brazil, from January 2012 to November 2013, with the cultivars SP79-1011, IACSP94-2101, IACSP94-2094 and IACSP95-5000 subjected to daily irrigations. The irrigations depths were applied to bring soil moisture to field capacity. Soil moisture was monitored using soil moisture probes. Samples were collected along the crop cycle in order to evaluate crop development and yield, at the end of the first and second ratoons. Stalk height showed good correlation for the estimation of crop yield, with R2 equal to or higher than 0.96. The cultivar IACSP95-5000 showed the highest yield in the first ratoon. In the second ratoon the highest yield was observed in IACSP94-2101, followed by IACSP95-5000 and SP79-1011. Considering the yield results associated with the technological analysis, such as soluble solids content and apparent sucrose, the cultivar IACSP95-5000 excelled the others in the cultivation under subsurface drip irrigation.
