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).

Field experiments were carried out during two seasons (August-February) of 2011-12 and 2012-13 at Millet Breeding Station, Tamil Nadu Agricultural University, Coimbatore, to study the effect of drip fertigation on productivity, water use and water use efficiency of pigeonpea (Cajanus cajan) cv. LRG 41. The treatments included three irrigation regimes (50 %, 75 %, 100 % computed water requirement of crop) and surface irrigation along with three fertilizer levels with water soluble fertilizer (WSF) and conventional fertilizers (CF). The treatments were laid out in Randomized Block Design with three replications. The results revealed that drip irrigation at 100 % WRc with fertigation at 125 % RDF through WSF registered significantly highest grain yield of 2812 and 2586 kg ha-1 during 2011-12 and 2012-13, respectively. Surface irrigation with conventional method of fertilizer application recorded lower water use efficiency of 3.70 and 3.38 kg ha-1 mm-1 whereas it was reverse with drip irrigation of 100 % WRc + 125 % RDF through WSF with a WUE of 6.97 kg ha-1 mm-1 during 2011-12 and during second season (2012-13), the highest WUE of 6.72 kg ha-1 mm-1 was recorded in drip irrigation at 50 % WRc along with fertigation at 125 % RDF through WSF. The increase in grain yield with drip irrigation at 100 % WRc + fertigation with 125 % RDF through WSF was mainly attributed by greater and consistent availability of soil moisture and nutrients which resulted in better crop growth, yield components and ultimately reflected on water use efficiency and yield of pigeonpea Cajanus cajan.

Sesame (Sesamum indicum L.) plays a vital role in the Indian agriculture, industry and export trade. It commonly known as til and also called as “queen of oilseeds” has been known to be one of the earliest domesticated edible oilseeds used by mankind. It is grown in wide range of environments extending from semi-arid tropics and subtropics to temperate regions. A field experiment entitled “effects of irrigation and nutrient management on summer sesame (Sesamum indicum L.)”,was conducted at the Agricultural Research Station, Brinjhagiri, Chatabar of Faculty of Agricultural Sciences, Siksha ‘O’ Anusandhan (Deemed to be University), Bhubaneswar (Odisha) during summer season of 2021. Treatments included three irrigation levels (I1: 2 irrigations at 21 and 63 days after sowing, I2: 2 irrigations at 21 and 42 days after sowingand I3: 3 irrigations at 21, 42 and 63 days after sowing) are treated in main plot and four nutrient management (N1: 100% RDF, N2: 100% RDF + 2 t/ha FYM, N3: 100% RDF + 2 t/ha FYM + Jeevamrut @250l/ha and N4: 75% RDF + 2 t/ha FYM + Jeevamrut @250l/ha) are treated in sub plot were experimented in split plot design replicate thrice. The experiment was conducted with the variety of TKG-21 followed the spacing of 30 cm × 10 cm. The experimental soil was sandy loam in texture with the pH of 5.65 and EC of 7.33 ds/m. The recommended dose of NPK was given 30:15:15 kg ha-1. From the experiment, highest seed yield (643.49 kg ha-1), haulm yield (1820.13 kg ha-1) and harvest index (26.04%) was obtained in I3. N4 (75% RDF + 2 t/ha FYM + Jeevamrut @250l/ha) showed second highest seed yield (652.21 kg ha-1), haulm yield (1882.07 kg ha-1) and harvest index (25.74%) which is at per with N3. Highest water use efficiency (2.72 kg ha-1 m-1) was calculated in I2N3. Hence, it can be conclude that cultivation of sesame under75% RDF + 2 t/ha FYM + Jeevamrut @250l/ha with 2 irrigations at 21 and 42 days after sowing proved better in terms of yield, economics and water use efficiency.

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
