Effect of planting density, irrigation and fertigation levels on water saving and water use efficiency of brinjal (Solanum melongenaL.)

Abstract

A field experiment was conducted during Rabi-hot weather of 2009-2010 at Department of Agronomy, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.). The soil of experimental field was sandy clay loam in texture and moderately acidic in reaction, medium in available N, low in available P 2 O 5 and high in K 2 O content. The experiment was laid out in Split Plot Design consisted of three planting density viz., S 1 -75×75cm, S 2 -75-50×90cm, S 3 -175-50×50cm and three irrigation levels (I 1 -100 % ET crop , I 2 -80 % ET crop , I 3 -60 % ET crop ). The sub plot treatment comprised of two fertigation levels viz., F 1 -100 per cent RDF through drip (WSF), F 2 -80 per cent RDF through drip (WSF). Thus, these eighteen treatments combinations were replicated thrice. Field water use efficiency (FWUE) was maximum i.e. 46.91 q ha -1 -cm in treatment combination of plant spacing S 3 (175-50×50cm) with I 3 (60 % ET crop ) and F 1 (100 % RDF through drip). The treatment wise saving of water over check basin irrigation method was 66.94, 78.47, and 88.94 per cent in the treatments I 1 (100 % ET crop ), I 2 (80 % ET crop ) and I 3 (60 % ET crop ), respectively.How to cite this paper : Ughade, S.R. and Mahadkar, U.V.

Effect of different spacing on varieties of Brinjal (Solanum melongena L.)

“…The ultra-density crop facilitate in maintaining the soil fertility status which leads to proper growth and development of crop with producing maximum plant spread. The results corroborate the findings made by Ughade and Mahadkar (2015) [11] in brinjal. Maximum number of branches per plant (4.21) at last harvest was recorded with treatment s 1 (90 cm × 90 cm).…”

“…With respect to varieties, significantly maximum fruit weight (80.04 g) was recorded with treatment v 1 (GJB3). Ughade and Mahadkar (2015) [11] nicely briefed the, wider spacing recorded statistically higher values of average weight of fruit under study. The maximum number of fruits per plant (28.24) was recorded in treatment s 1 (90 cm ×90 cm) and varieties, significantly maximum number of fruits per plant (32.14) was recorded with treatment v 3 (Doli 5).…”

Influence of infield variability in irrigation and fertigation levels on growth and yield of summer chilli (Capsicum annuum L.)

“…While insufficient water inhibits leaf expansion and photosynthetic capacity. Similar results are reported by Ughade and Mahadkar (2015) [18] for brinjal. Whereas, application of different levels of fertigation had non-significant effect on plant spread of chilli at 30 and 60 DAT and found significant at 90 and 120 DAT.…”

Effect of Drip Irrigation and Fertigation on Growth, Development and Yield of Vegetables and Fruits

“…Harmanto et al, (2005) concluded that the drip irrigation at 75% of ETc provided the maximum crop yields and irrigation water productivity in tomato variety Troy 489 under tropical greenhouse conditions. Ughade and Mahadkar (2014) reported that the brinjal crop under Field water use efficiency (FWUE) was maximum under treatment 80% ET with100 % RDF drip fertigation while comparing with 100 and 60% ET with RDF drip fertigation. Patel and Rajput (2007) reported that the potato yield was Maximum when irrigation was applying at the 100% of the crop evapotranspiration (23.6 cm of irrigation water) and by placing the drip tape at 10.0 cm depth followed by 15.0 cm and 20.0 cm depth.…”
