Temporal analysis of drought using standardized precipitation index for Wainganga sub-basin, India

Abstract

The experiment was conducted at research farm of the Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2016 to assess the effect of repeated application of herbicides on fruit yield and quality of Kinnow. The treatments comprising eleven levels which were laid out in a randomized block design with three replications on four years plants. Maximum values for length of fruit (7.10 cm), breadth of fruit (7.33 cm), fruit weight (181.00 g), number of fruits per tree (189.0), yield(33.0 kg), TSS (9.43 %), maximum juice content (55.33%) and ascorbic acid (33.00 mg) was recorded with glyphosate 1%+ pendimethalin 1 kg/ha) in April, June, August and October while minimum acidity (0.76%) was recorded with paraquat 0.6% + pendimethalin 1 kg/ha in April, June and August.
