panchagavya 3 per cent. The nutrient contents (NPK) of the plant tissues also registered the
highest when vermicompost @ 2.5 t ha -1 along with foliar spray panchagavya 3 per cent was
applied. With regard to the postharvest available soil nutrients, the results revealed that
application of vermicompost @ 2.5 t ha -1 along with foliar spray panchagavya 3 per cent
recorded the highest organic content in soil. Hence it could be concluded that the treatment
combination of vermicompost @ 2.5 t ha -1 along with foliar spray panchagavya 3 per cent is
best suited to grow Gundumalli (JasminumsambacAit.) in field condition to achieve good
growth, profuse flowering and flower yield.

In dryland area the distribution of rainfall is highly erratic and the occurrence of dry spells
during the crop growth stages is indispensable resulting in failure of crop or realization of
uneconomical yield. Harvesting of rainwater through farm ponds during the rainy season and
recycling it for use as supplemental irrigation at the critical stages of the crop can help to
mitigate the effect of dry spells and to overcome the loss of yield under dryland condition for
Rabi cropping after Kharif. Several researchers have shown that on farm in-situ run off
collection of rainwater in to farm ponds and its utilization in dry spells as supplemental
irrigation can increase and stabilize the crop production (Krishna et al. 1987).
Methodology
This experiment was conducted 2017-18 to 2020-21 and pooled data has been presented for
study purpose. The experimental soil is silty clay loam, medium in organic carbon and low in
available nitrogen and Phosphorus while potassium status was medium. Water harvesting
tank size is 60 m X 30 m. Total harvested water was 3867m 3 while 1850 m 3 water was used
for irrigation. Water losses through seepage and evaporation was 1160 M 3 . During Kharif
Soybean and Rice crops were grown under dryland condition while in Rabi wheat, chickpea,
Mustard and coriander crops were taken which were given supplemental life saving irrigation
from water harvested pond. All the crops were fertilized by recommended doses of fertilizers
under dryland condition.
