Water and nutrient deficiency are two major constraints that drastically affect rapeseed and mustard production under semi-arid regions of North-Western India. To cope with this problem, a study was undertaken to optimize irrigation, nitrogen and sulphur levels for productivity and quality of Ethiopian mustard(Brassica carinata).Field experiments were conducted during winter seasons of 2004-05 and 2005-06 at the Water Technology Centre (WTC), Indian Council of Agricultural Research (ICAR) – Indian Agricultural Research Institute (IARI), New Delhi, India. Irrigation, nitrogen and sulphur levels significantly (P<0.05) affected plant height, LAI, siliqua weight, seeds/siliqua, test weight, seed and biomass yield of Ethiopian mustard. Application of three irrigations (seedling, 50% flowering and pod development stage) to Ethiopian mustard   increased seed yield by 27-28% compared to one irrigation (seedling stage). Nitrogen @ 90 kg ha-1 produced 49-54 % higher seed yield of Ethiopian mustard compared to no application. Similarly, sulphur application @ 40 kg ha-1 increased seed yield by 33-34 % compared to no application of sulphur. The oil content of Ethiopian mustard   was significantly (P<0.05) affected by nitrogen and sulphur levels. Among the three treatments, irrigation treatment only significantly affected evapotranspiration of the studied crop. From the above study, it is suggested that application of  3 irrigations with 90 kg N ha-1 and 40 kg S ha-1 may be practiced for achieving higher seed yield, quality and water use efficiency of Ethiopian mustard in the semi-arid environment of Northern part of India.

One of the major factors limiting the production of medicinal plants in arid and semi-arid areas is water deficit or drought stress. One-third of the land in the world is arid and semi-arid and is inhabited by nearly 4 × 108 people. Ocimum basilicum (sweet basil) is a valuable medicinal plant that is sensitive to water deficit, and water shortage negatively affects sweet basil yield and quality. Water availability in the root zone of basil could ameliorate the negative effects of water shortage. To the best of our knowledge, although the effects of hydrophilic polymers (HPs) have been studied in different agricultural crops, the effects of HP application in medicinal plants have not been previously investigated. This investigation was conducted to explore the effects on water use efficiency when using Stockosorb® (STS) and psyllium seed mucilage (PSM) as hydrophilic polymers (HPs) and the effects of these HPs on essential oil quality, quantity, and yield. The research was set up in a factorial experiment on the basis of completely randomized block design with three replications. We used two HPs, STS (industrial) and PSM (herbal), with two methods of application (mixed with soil, mixed with soil + root) at four concentrations (0%, 0.1%, 0.2%, and 0.3% (w/w)). Results showed that the STS and PSM significantly increased the dry herb yield (both shoot and root) in comparison to the control, and the improving effect was higher when these HPs were mixed with soil + root. The highest dry herb yield (6.74 and 3.68 g/plant for shoot and root, respectively) was detected in the PSM at 0.1% mixed with soil + root. There was not any significant difference in dry herb yield among PSM (0.1%), PSM (0.2%), and STS (0.2%) when mixed with soil + root. Soil application of PSM and soil + root application of STS at a concentration of 0.3% increased the Essential Oil (EO) content almost three-fold in comparison to the control (0.5% and 0.52% to 0.18% v/w, respectively). The maximum essential oil yield was recorded in plants treated with STS (0.2% in) or PSM (0.1%) by soil + root application (0.21 and 0.19 mL/plant, respectively). PSM at concentrations of 0.1% and 0.2% (mixed with soil + root) showed the highest water use efficiency (1.91 and 1.82 g dry weight (DW)/L H2O, respectively). STS mixed with soil also significantly improved water use efficiency (WUE) in comparison to the control. The application of these HPs improved the quality of sweet basil essential oil by increasing the linalool and decreasing the eugenol, epi-α-cadinol, and trans-α-bergamotene content.

A field experiment was conducted during kharif season of 2009 and 2010 in a sandy loam soil of New Delhi to study the effect of weather, achieved by sowing at normal (D1) and late (D2), on soil moisture prediction, evapotranspiration (ET), yield and water use efficiency (WUE) of three varieties (V1: JS 335, V2: Pusa 9712 and Pusa 9814) of soybean. Study of soybean phenology showed that there was reduction in the number of days taken for the crop to complete life cycle with delayed sowing. The agrometeorological water balance model could satisfactorily predict soil moisture content during soybean crop growth period with RMSE (%) varying between 6.27 to 12.06 and correlation coefficient between 0.828 to 0.982. The ET decreased significantly with delay in sowing; however there was no significant variation among the varieties. Among the stages of the soybean crop, mid season stage had highest ET followed by development stage, late season stage and initial stage. Normal sowing resulted in higher yield but lower WUE than the late sowing. Among the cultivars, JS 335 resulted in lower yield and WUE than Pusa 9712 and Pusa 9814. It may be recommended that, Pusa 9712 or Pusa 9814 may be sown during first and second week of July (normal sowing) to achieve higher yield in the semi-arid environment of Delhi region.
