Application of water soluble fertilizer @ T4-150:75:150 NPK kg/ha through fertigation either with mulch (14.05q/ha) or non-mulch (11.83q/ha) recorded significantly higher seed yield than fertilization through soil application (9.92 q/ha). The increased seed yield of 16.91 and 10.14 per cent was noticed in fertigation with mulch or without mulch treatment over soil application, respectively. NPK fertigation @150:75:150kg per ha with mulch (T4) resulted in higher NPK uptake in stem (63.49, 14.12&121.42 kg/ha), leaves (117.65 19.42&122.43 kg/ha) and in fruits (146.79 28.05&162.66 kg/ha), respectively than the fertilizer applied through soil at harvest. Maximum fertilizer use efficiency and water use efficiency were recorded in the treatment with integrated application of fertigation and mulch.

Drip Fertigation

Background: Pigeonpea an indeterminate pulse crop with profuse branching responds well to both irrigation and fertilizer. Erratic rainfall distribution pattern exposes this crop to dry spell during its vegetative stage and terminal drought at reproductive stage and the poor crop nutrition further results in to low yield. Under such circumstances it is very difficult to sustain the yield of pigeonpea. Agronomic practices like precise and timely application of drip irrigation along with judicious use of nutrients play a vital role to boost the yield of any crop. Thus the attempts were made to explore the yield potential of pigeonpea under drip irrigation and fertigation management. Methods: The present study was conducted at the experimental farm of AICRP on Irrigation Water Management, VNMKV, Parbhani (MS) during kharif 2018 and 2019. The experiment was laid out in split plot design with main plots comprising of four drip irrigation levels viz. 0.6, 0.8, 1.0 ETc (crop evapotranspiration) and conventional method and sub plots were allotted to four fertigation levels viz. control (no fertilizer), 80% RDF, 100% RDF (25: 50: 25 NPK kg ha-1) and 120% RDF. Result: Drip irrigation at 0.8 ETc recorded higher seed yield, harvest index, water use efficiency, nutrient use efficiency and net returns of pigeonpea followed by 1.0 ETc except in case of water use efficiency. As regards to fertigation studies, higher values of seed yield, harvest index and water use efficiency were recorded with drip fertigation @ 25:50:25 NPK kg ha-1 closely followed by 20:40:20 NPK kg ha-1. However higher nutrient use efficiency and net returns were obtained in drip fertigation @ 20:40:20 NPK kg ha-1.

An investigation was carried out on sandy loam soils of semi arid regions of southern Telangana to analyze the potential of drip irrigation along with mulch on mango fruit yield, water and nutrient use efficiency. The treatments of present study were comprised of two levels mulching (M0-without mulch and M1-with mulching), with silver Polyethylene of 100 micron thickness were used and two levels of irrigation (I1 -75% and I2 100% ETc through drip), here irrigation levels and mulching together constituting four treatment combinations with five replications under 2x2 factorial randomized block design and the treatment combinations are: I1M0-75% ETc + No mulching, I1M1- 75% ETc + with mulch, I2M0- 100% ETc + No mulching and I2M1- 100 % ETc + with mulch.  The study revealed that drip irrigation 100% ETc along with silver polythene mulch showed better performance in terms of yield, water use efficiency, nutrient use efficiency as well as economics. Maximum yield of 89.11 kg tree-1 combination of 75 % ETc + with mulching has proven the maximum water use efficiency (5.54 g liter-1 water consumption) and fertilizers use efficiency (0.89 q kg-1 fertilizer application) however along with maximum net return of 400973. 90 rupees ha-1, net return of 346873.90 ha-1 per hectare and B: C ratio of 7.41 was recorded in I2M1 (100 % ETc + with mulch). So the experiment suggests that drip irrigation along with mulch has the potential to provide greater benefit by optimizing the use of water resources. But the interaction of 75 % ETc + with mulching has proven the maximum water use efficiency (6.28 g liter-1 water consumption).

This chapter considers the challenge of improving crop resource-use efficiency using biotechnology or traditional plant breeding. It argues that some of biotechnology's stated goals, such as more efficient use of water by crops, are unlikely to be achieved without tradeoffs. After providing an overview of crop genetic improvement via traditional plant breeding or biotechnology, the chapter discusses the importance of greater resource-use efficiency and increasing yield potential. It then explains how natural selection has improved the efficiency of photosynthesis as well as water-use efficiency and how tradeoffs limit biotechnology improvement of crop water use. It also assesses the potential of genetic engineering to improve nutrient-use efficiency and asserts that near-term benefits of biotechnology have been exaggerated. The chapter concludes with a review of biotechnology's possible benefits and risks.

Sustainable agricultural systems are necessary to improve soybean [Glycine max (L.) Merr.] seed yield and to increase nutrient use efficiency. Intensification of agricultural systems is an important tool to increase farmers’ profitability in the Cerrado region (Brazil), where soybean is rotated with corn in the same growing season. However, this intensification requires soybean cultivar with short growing periods which is achieved by indeterminate soybean cultivars. There is a lack of information regarding the nutrient uptake by soybean cultivars under intensive agricultural systems in the Cerrado. We sought to investigate soybean biomass production and soybean seed yield of determinate and indeterminate soybean cultivars. We also aimed to quantify the amounts of nutrients taken up by soybean biomass and seeds. Field research was conducted to evaluate 17 soybean cultivars commonly grown by farmers, and we considered the determinate and indeterminate soybean growth habit. Nutrient uptake and aboveground soybean biomass were higher under shorter soybean growth and development cycles. Nitrogen, phosphorus and potassium extraction in modern cultivars was higher than in cultivars used in past decades. Nutrient use efficiency was higher in determinate soybean cultivars than in indeterminate soybean cultivars.

A field experiment was conducted during 2010-2011 in medium deep clay soils at the Research Farm of Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra to find out the effect of drip fertigation on yield and nutrient use efficiency of banana (cv. Grand naine). The treatments comprised of 100, 80 and 60 % recommended dose (RD) of fertilizer applied through drip in two schedules (Schedule A-equal, Schedule B crop growth stage), drip irrigation with only N through drip, drip with conventional fertilizers through soil and surface irrigation as control. The drip irrigation increased banana yield by 59.6 per cent and saved fertilizer to the tune of 40 per cent .The treatment comprising of 100 % RD of fertigation (schedule B) had maximum banana yield (81.84 t ha-1) over surface irrigation (51.26 t ha-1), however, it was at par with 100 % RD of fertigation in uniform 16 splits and 80 % RD of fertigation. Application of water soluble fertilizers through drip resulted in highest nutrient availability than control. In general, 100 % RD had the highest nutrient availability than 80 % and 40 % RD of fertilizer. The nutrient availability was more in treatment in which fertilizers were applied as per growth stages (schedule B) than equal splits (schedule A). The uptake of nutrients was higher in fertigated treatments than other treatments
