Abstract:
The field experiment was conducted during
Rabi season of 2017-18 at the Research cum Instructional Farm, under all India Coordinated Research Project on MULLaRP, Department of Agronomy, College of Agriculture, I.G.K.V. Raipur (CG.) on ‘The effect of irrigation and foliar spray of nutrients and growth hormones on nutrient uptake and water use efficiency of lentil’ The experiment was laid out in Strip Plot Design having the combination of fourteen treatments and three replications. The treatment consisted of seven foliar nutrients spray and two irrigation levels. The experiment was comprised of factor A. Horizontal plot (Irrigation level-2) I
1-One irrigation (35 DAS), I
2-Two irrigation (35 and 65 DAS) B. Vertical plot (Foliar Spray-7) F
1-Water Spray, F
2-Nitrobenzene @ 0.3%, F
3-N: P: K:: 19:19:19 @ 1% solution, F
4-Multi micro nutrient (Fe, Mn, Zn, B, Cu, Mo) @ 0.1%, F
5-Plant growth hormones mixture (Cytokinins and Enzymes) @ 0.15%, F
6-N: P: K:: 19:19:19:@ 1% + Multi micro nutrient (Fe, Mn,Zn, B,Cu,Mo) @ 0.1%, F
7-N: P: K: 19:19:19 + Multi micro nutrients + Plant growth hormones. Significantly maximum N, P and K uptake in seed, stover as well as in total was recorded with I
2-Two irrigations followed by I
1-One irrigation. As regards to foliar spray, significantly higher N, P and K uptake in seed, stover and in total was noted under F
7-N: P: K: 19:19:19 + MMN + PGHM as compared to others, however, it was at par to treatmentsF
6- N: P: K: 19:19:19: + MMN, F
3-N: P: K:: 19:19:19 @ 1% and F
4-Multi Micro Nutrients. Between the irrigation levels, significantly higher water use efficiency (86.79 kg ha
-1cm) was recorded with I
1-One irrigation as compared to I
2-Two irrigation (66.06 kg ha
-1cm). As regards to the foliar spray of micronutrients and growth hormones, maximum water use efficiency (89.56 kg ha
-1cm) was recorded with F
7- N: P: K:: 19:19:19 + MMN + PGHM. However, it was at par to treatment F
6-N: P: K: 19:19:19 + MMN (82.13 kg ha
-1). The minimum water use efficiency (58.03 kg ha
-1cm) was observed with F
1- Control (water spray).
