during the growing period of 2016-17 and 2017-18 to investigate the effect of different N, P and K interaction levels on nutrient uptake by dolichos bean and post harvest fertility status of soil. The field experiment was laid out in randomized block design comprising of eighteen treatments replicated thrice. Amongst all NPK fertilizer levels, higher fertilizer dose of 25:75:50 kg NPK per hectare recorded significantly maximum plant height, number of secondary branches and dry matter content per plant at harvest however, it was onpar with 25:75:25 kg NPK per hectare except dry matter content per plant in both the years (2016-17 and 2017-18) and pooled data respectively. However, pooled analysis data revealed that green pod yield per plant and pod yield per hectare as well as higher total N, P and K uptake were recorded significantly maximum in 25:75:50 kg NPK per hectare but the trend was different during both the experimental years. Physico-chemical properties of soil such as soil pH, EC, OC in soil after final harvest of dolichos bean were significantly influenced by NPK interactions levels during both the years (2016-17 and 2017-18) of investigation and in pooled data analysis except soil pH in 2017-18 growing season. Pooled data revealed that significantly highest available nitrogen, phosphorus and potassium availability in soil were recorded in higher fertilizer dose of 25:75:50 kg NPK per hectare which was onpar with 25:75:25 kg NPK per hectare except available potassium. Similar trend was also observed during the year 2016-17 and 2017-18 experimental years.

A field experiment was conducted to investigate the effect of different N, P and K levels on growth, yield and quality parameters of edible poded dolichos bean at Kittur Rani Channamma College of Horticulture, Arabhavi, during the growing period of 2016-17 and 2017-18. The nitrogen (0 and 25 kg/ha), phosphorus (0, 50 and 75 kg/ha) and potassium (0, 25 and 50 kg/ha) were applied in eighteen different combinations. Among indivisual NPK levels, the higher level of nitrogen (25 kg N/ha), phosphorus (75 kg P2O5/ha) and potassium (50 kg K2O/ha) recorded significantly maximum growth (plant height, number of primary branches, number of leaves), pod yield (162.32, 184.14 and 164.75 q/ha) and quality parameters (fiber, sugar and protein) of dolichos bean compared to lower levels in both the years (2016-17 and 2017-18) and pooled data, respectively. Similarly, among NPK interaction levels, higher fertilizer dose of 25-75-50 kg N-P2O5-K2O/ha (T18) registered the highest value for growth and yield parameters but it was on par with 25-75-25 kg N-P2O5-K2O/ha (T17) for all the characters except number of leaves and days to crop maturity during both the experimental years as well as in pooled data. Therefore, for obtaining high yield with good nutritive value, NPK fertilizer must be applied at the rate of 25-75-25 kg/ha under the Arabhavi (Karnataka) condition.

Belagavi district during rabi-2015-16 and 2016-17 to study the effect of integrated nutrient management on growth and yield of fennel (Foeniculum vulgare Mill.). The experiment was laid out in randomized complete block design and treatments were replicated thrice. The experiment consisted of twelve treatments. Among the different treatments, significantly higher seed yield per plant and hectare was recorded with T 6 -RDFYM+ 75% RDN + RDPK + Azospirillum at 5 kg ha -1 +PSB at 3 kg ha -1 (30.47 g plant -1 and 2.29 t ha -1 , respectively) this was on par with T 4 -vermicompost at 2.5 t ha -1 + RDNPK+ Azospirillum at 5 kg ha -1 +PSB at 3 kg ha -1 (29.85 g plant -1 , 1.44 kg plot -1 and 2.21 t ha -1 , respectively). Significantly higher growth and yield parameters viz., plant height (209.97cm), number of primary and secondary branches (16.43 and 7.50, respectively), maximum number of umbels per plant (29.24), number of umbellets per umbel (23.68), number of seeds per umbellate (35.07) and test weight (7.35 g) were recorded with treatment receiving T 6 -RDFYM+ 75% RDN + RDPK + Azospirillum at 5 kg ha -1 +PSB at 3 kg ha -1 .
