Abstract
The present experiment entitled "Studies on the effect of organic nutrient sources on soil
properties and yield of French bean (Phaseolus vulgaris L.) in Sub - tropics of Himachal
Pradesh" was conducted at experimental farm of the Department of Soil Science and Water
Management, College of Horticulture and Forestry, Neri, during two seasons of year 2019. Nine
treatment combinations viz. T1 (Jivamrit @ 5% at weekly interval), T2 (FYM @ 20t/ha + R.D.F), T3
(FYM @ 20t/ha + Jivamrit @ 5% at weekly interval), T4 (FYM @ 20t/ha + Jivamrit @ 5% at
fortnight interval), T5 (Vermicompost @ 5t/ha + R.D.F.), T6 (Vermicompost @ 5t/ha +Jivamrit @ 5%
at weekly interval), T7 (Vermicompost @ 5t/ha + Jivamrit @ 5% at fortnight interval), T8 (Jivamrit @
5% + Ghanjivamrit at fortnight interval) and T9 (R.D.F.) were tried in triplication with a randomized
block design. Minimum days to 50% germination (5.33) and days to 50% flowering (30.33) were
recorded in T6 treatment. Maximum plant height at 30 (27.98 cm), 45 (38.20 cm) and 60 (41.30 cm)
DAS; number of branches plant-1
at 30 (3.71), 45 (4.84) and 60 (6.11) DAS; yield plant-1
(51.45 g);
yield hectare-1
(6.84 t) and yield attributing characters viz. number of green pods plant
-1
(9.70), length
of green pods (14.21 cm), total dry matter plant-1
(32.84 g) were recorded in T6 treatment. Highest
(283.33) count of nodules plant-1
, plant K content (1.14%) and K uptake (51.09 kg ha-1
) was recorded
in T3 treatment. Maximum plant N (2.64%), P (0.80%), Zn (19.10 ppm), Fe (117.93 ppm), Cu (6.47
ppm) and Mn contents (16.31 ppm) were recorded in T6 treatment. The highest N (95.31 kg ha-1
) and
P (36.79 kg ha-1
) uptake were recorded in T6. Further, TSS and moisture content in pods, soil bulk
density, particle density, porosity, soil pH and EC did not differ significantly with organic nutrients
treatment. Highest value for soil available N (288.19 kg ha-1
), K (187.56 kg ha-1
) and DTPAextractable cations viz. Zn (2.05 mg kg-1
), Fe (10.01 mg kg-1
), Cu (2.71 mg kg-1
) and Mn (10.76 mg
kg-1
) was recorded in T6. Maximum soil available P (32.97 kg ha-1
) and S (62.43 kg ha-1
) were
recorded in T3 and T7, respectively. Furthermore, maximum total viable microbial population (72.67 x
105
cfu g-1
) in soil was recorded in T6 treatment. The application of vermicompost @ 5t/ha +Jivamrit
@ 5% at weekly interval increased yield hectare-1 by 16.1 per cent over recommended practice.
