Chrysanthemum (Dendranthema grandiflora Tzvelev.) has earned tremendous popularity as a floral crop in Madhya Pradesh, particularly at Indore, Madhya Pradesh , India where it is being commercially cultivated as loose flowers in open field condition during June to January. However, lower production and poor quality of flowers were observed due to haphazard and unbalanced use of inorganic fertilizers and non use of biofertilizers. With the objectives to tackle the issue of low productivity and quality of flowers, dissemination of recommended technology was successfully attempted during 2015-16 and 2016-17. The technologies of balanced use of inorganic fertilizer with bioferetilizer (Azotobactor and PSB) were used as technical intervention. The collective effect of scientific intervention revealed an average yield of 113 quintal / ha, which is 14.76 % higher over farmer’s practice. Average net returns from recommended technology were observed to be of Rs. 1, 88,100 as compared to Rs. 1, 54,350 under farmer’s practice (control). Thus, an additional income of Rs 33,750 was realized through imparted technological intervention provided in demonstration plots. Cost-benefit ratio of recommended practice (2.25) was observed to be significantly higher over farmer’s practice (2.17). Enhanced economic benefit and favorable C: B proved the economic feasibility of the technological intervention and was convincing for the farmers, for further future adoption. At present scenario, organic fertilizers including bio fertilizers are becoming indispensable input to minimise our compulsion on synthetic fertilizers.
Aim: To study the combined effect of tillage and manure addition on bulk soil and aggregate associated carbon and nitrogen in Vertisol. Methodology: The study was conducted in a long-term tillage experiment having two tillage treatments (reduced tillage and no-tillage) together with100% NPK fertilizer without (T1) and with addition of farm yard manure (T2) @ 2.0 ton C ha-1 to soybean in a soybean-wheat cropping system in a Vertisol of Central India, with three replicates in a split plot design. The parameters studied were aggregate size distribution, mean weight diameter, water stable aggregates, bulk soil and aggregate associated organic carbon, available nitrogen and rate of carbon mineralization. Results: The results indicated significantly higher SOC in reduced tillage (0.87%) than no-tillage (0.71%) under100% NPK fertilization in the bulk soil for 0-15 cm depth. However, 100% NPK + FYM showed a significant increase in the bulk soil organic carbon in the no-tillage treatment only. Available nitrogen content in the bulk soil and aggregate fractions were significantly lower under no-tillage than the corresponding reduced tillage treatments. Manure addition led to significantly higher available N content and proportion of WSA in both the tillage practices. The carbon mineralization was significantly higher by 1.4 to 1.6 times under reduced tillage than no-tillage. Interpretation: Long-term tillage study in Vertisol of Central India indicated reduced tillage to be a better option than no-tillage in maintaining organic carbon and nitrogen availability in soil.
: A field experiment was conducted during the Kharif season of 2014-15, 2015-16 and 2016-17 at KVK, Indore to study the effect of different land configuration on the yield of soybean. The experiment consisted of three treatments of land configuration, viz., T 1 (FIRBS layout), T 2 (Ridge and furrow layout), T 3 (BBF layout), under RBD design with seven replications. Result showed that significant increase was observed in yield contributing characters viz., number of pods plant -1 , 100 seed weight (g), seed yield (q ha -1 ) and harvest index (%) in FIRBS layout as compared to ridges and furrow and broad bed furrow. The net return is the best index of profitability of soybean crop and higher net return per ha of Rs. 24699 was recorded for soybean crop under the FIRBS whereas lower net return per ha of Rs. 20808 was recorded under BBF land configuration.
