Abstract
The present investigation entitled “Studies on effect of integrated nutrient management on kasuri methi (Trigonella corniculata L.) var. Pusa Kasuri under Telangana conditions” was carried out during the rabi season of the year 2018-19 at College of Horticulture, Rajendranagar, Hyderabad.
The results related to growth parameters indicated that, among the treatments, T3 - 75% RD NPK + FYM (7.5 t ha-1) + Rhizobium (1.5 kg ha-1) + Azospirillum (5 kg ha-1) + PSB (5 kg ha-1) recorded maximum plant height (45.85 cm), significantly more number of branches per plant (26.47), maximum plant spread (North-South 31.03 cm and East-West 32.65 cm) and significantly broader leaf area (411.91 cm²) over other treatments.
All treatments differed significantly with respect to yield parameters. Among the treatments, T3 - 75% RD NPK + FYM (7.5 t ha-1) + Rhizobium (1.5 kg ha-1) + Azospirillum (5 kg ha-1) + PSB (5 kg ha-1) recorded significantly highest fresh herb yield per plant and per hectare (31.23 g and 7808.33 kg, respectively), dry herb yield per plant and per hectare (7.30 g and 1825.00 kg, respectively), maximum number of days taken to first and 50 per cent flowering (61.67 days and 84.67 days, respectively), significantly more number of pods per plant (617.47), pod length (2.08 cm), maximum number of seeds per pod (6.02) and the same treatment also registered significantly highest seed yield per plant and per hectare (1.71 g and 427.50 kg respectively) and maximum test weight (1.64 g) as compared to other treatments.
The results pertaining to quality parameters revealed that, significantly the highest crude protein content of herb and seed (10.41% and 19.97% respectively) and total chlorophyll content (23.68 mg/100 mg of tissue) were recorded in T3- 75% RD NPK + FYM (7.5 t ha-1) + Rhizobium (1.5 kg ha-1) + Azospirillum (5 kg ha-1) + PSB (5 kg ha-1) over other treatments.
The results related to soil and plant nutrient status showed that, among the treatments, T3- 75% RD NPK + FYM (7.5 t ha-1) + Rhizobium (1.5 kg ha-1) + Azospirillum (5 kg ha-1) + PSB (5 kg ha-1) recorded maximum availability of nitrogen (204.57 kg ha-1), significantly more phosphorous (49.50 ha-1) and higher potassium content (172.50 kg ha-1) in soil and also the same treatment registered significantly maximum nitrogen, phosphorous and potassium content in herb, straw and seed (1.67%, 1.37% and 3.20%, 0.54%, 0.39% and 0.60%, 0.51%, 0.83% and 0.43% respectively) as compared to rest of the treatments.
There was significant difference was observed among the treatments with respect to N, P and K uptake by plant, significantly maximum nitrogen, phosphorous and potassium uptake (72.64 kg ha-1, 20.54 kg ha-1 and 28.38 kg ha-1 respectively) was recorded in T3- 75% RD NPK + FYM (7.5 t ha-1) + Rhizobium (1.5 kg ha-1) + Azospirillum (5 kg ha-1) + PSB (5 kg ha-1) over other treatments.
The data on economics revealed that, among the treatment, T3- 75% RD NPK + FYM (7.5 t ha-1) + Rhizobium (1.5 kg ha-1) + Azospirillum (5 kg ha-1) + PSB (5 kg ha-1) registered the highest gross returns (Rs. 189058.3), net returns (Rs. 135542.4) with cost benefit ratio (1: 2.52) over other treatments.
