Abstract
The investigation entitled “EFFECT OF DATES OF SOWING ON
YIELD AND QUALITY OF SEEDS IN GARDEN CRESS (Lepidium sativum
L.)” was conducted at Medicinal and Aromatic Plant Research station,
Rajendranagar, Hyderabad during the period of September 2015- March 2016. The
experiment was laid in Randomized Block Design with 8 planting dates as
treatments. The treatments were replicated three times.
The study consisted of 8 treatments with different dates of sowing viz., (i)
15th September (T1) (ii) 30th September (T2) (iii) 15th October (T3) (iv) 30th October
(T4) (v) 15th November (T5) (iv) 30th November (T6) (vii) 15th December (T7) (viii)
30th December (T8). Five plants were selected at random from each treatment and
tagged for recording biometric observations. The data were recorded at an interval of
30, 60, DAS and at harvest for assessing growth parameters like plant height,
primary branches, dry matter production of whole plant and recorded maximum
values in 30th October sown crop (T4).
Physiological parameters like Leaf Area Index, Absolute Growth Rate, Crop
Growth Rate and Relative Growth Rate recorded maximum values for 30th October
sowing for 30 DAS and 60 DAS resulted and where as minimum LAI and RGR
were recorded in 15th September sowing (T1) but AGR and CGR recorded minimum
values in 30th December (T8).
Among yield attributes viz., siliquae plant -1, seed yield plant-1, seed yield plot-
1, seed yield ha-1, harvest index (%), test seed weight (g) recorded significantly
maximum in 30th October (T4) sowing. Minimum values were recorded in 30th
December (T8) sowing. Number of seed siliqua-1 was non-significant with all dates
of sowing.
Quality parameters like vitamin C content in leaves (mg/100g), mucilage
content (%) recorded significantly maximum values in 30th October sowing (T4) and
minimum with 30th December (T8). Total phenol content (mg/100g) was nonsignificant
with all dates of sowing.
The present investigation conducted under Hyderabad conditions has revealed
that sowing of Garden cress on 30th October resulted maximum values in all the
parameters including B:C ratio (6.01:1). The minimum B:C ratio (3.01:1) was
recorded with 15th September sown crop (T1) in garden cress.
Correlation studies revealed that Temperature (max) was significantly
correlated negatively with number of primary branches and seed yield. Temperature
(min) was significantly correlated negatively with plant height, dry matter
accumulation, siliquae plant-1 and all other quality parameters. RH-I was negatively
correlated with plant height, number of primary branches and seed yield whereas,
RH-II correlated positively with vitamin C content in leaves (mg/100g) and it is nonsignificant
with all other growth, yield and quality parameters. Rainfall showed
negative correlation with dry matter accumulation. Regression studies showed
significantly positive association with seed yield with growth and yield parameters.
