Background: Intensive rice cultivation for longer periods continuously resulted in poor soil fertility. Inorganic fertilizers along with integrated and judicious use of different organic sources like FYM, vermicompost, green manure etc. could be an effective choice for enhancing crop yield. A synergistic effect on crop yield is reported through common use of fertilizer and organics which also improve soil fertility. The residual effects of organic manures applied to the preceding crops can be available to succeeding crop. Therefore, this experiments was planned to throw light on the use integrated nutrients through organic and inorganic sources on rice and its residual effect on succeeding greengram. Methods: A field experiment was conducted to study the effect of integrated nutrient management on rice-greengram cropping sequence at Navsari Agricultural University, Gujarat during 2012-15. Five nutrient combinations were evaluated in randomized block design for rice and its residual effect on productivity on succeeding greengram was studied with three fertilizer levels in split plot design. Result: Application of general recommended dose of fertilizers (RDF) to rice has increased growth, yield, quality, economics and improved soil properties and the residual effect to succeeding greengram have also gave significantly higher greengram seed yield and other important parameters and this was succeeded by application of 75% RDF through chemical fertilizer + 25% RDF through vermicompost. Among different levels of fertilizers to greengram, application of 100% RDF gave highest greengram seed yield, economics and soil parameters over other two levels.

Reliance on inorganic fertilizers with less or no use of organic fertilizers has impaired the productivity of soils worldwide. Therefore, the present study was conducted to quantify the effects of integrated nutrient management on rice yield, nutrient use efficiency, soil fertility, and carbon (C) sequestration in cultivated land. The experiment was designed with seven treatments comprising of a zero input control, recommended inorganic fertilizers (RD), poultry manure (PM) (5 t ha−1) + 50% RD, PM (2.5 t ha−1) + 75% RD, vermicompost (VC) (5 t ha−1) + 50% RD, VC (2.5 t ha−1) + 75% RD, and farmers’ practice (FP) with three replications that were laid out in a randomized complete block design. The highest grain yield (6.16–6.27 t ha−1) was attained when VC and PM were applied at the rate of 2.5 t ha−1 along with 75% RD. Uptake of nutrients and their subsequent use efficiencies appeared higher and satisfactory from the combined application of organic and inorganic fertilizers. The addition of organic fertilizer significantly influenced the organic carbon, total carbon, total nitrogen, ammonium nitrogen, nitrate nitrogen, soil pH, phosphorus, potassium, sulfur, calcium, and magnesium contents in post-harvest soil, which indicated enhancement of soil fertility. The maximum value of the organic carbon stock (18.70 t ha−1), total carbon stock (20.81 t ha−1), and organic carbon sequestration (1.75 t ha−1) was observed in poultry manure at the rate of 5 t ha−1 with 50% RD. The soil bulk density decreased slightly more than that of the control, which indicated the improvement of the physical properties of soil using organic manures. Therefore, regular nourishment of soil with organic and inorganic fertilizers might help rejuvenate the soils and ensure agricultural sustainability.

To evaluate the effects of integrated nutrient management on growth and yield of BARI tomato-14 and soil fertility, a pot experiment was conducted in the net house of the department of Agricultural Chemistry of Bangladesh Agricultural University, Mymensingh during the period from October 2011 to April 2012. The experiment was laid out in a completely randomized design with 11 treatments and 3 replications. Treatments were control, RDCF100, 75% RDCF, 50% RDCF, 75% RDCF + PM2 t /ha, 75% RDCF + RS3 t /ha, 75% RDCF + PHRD, 50% RDCF + PM3 t /ha, 50% RDCF + RS5 t /ha, 50% RDCF + PHRD, PM3 t /ha + RS5 t /ha + PHRD. Among the treatments applied in combination of PM2 t /ha+ 75% of RDCF excelled in growth trends of morphological characters like plant height, number of branches plant- 1, number of leaves plant-1; available soil P and S. But sole application of RDCF100 recorded higher values for almost all morphological characters namely number of branches plant-1, number of leaves plant-1, fruit diameter, fruit weight plant-1 and yield of tomato following the same trend as seen in combined application of CF and PM. Among the plant hormone applied in combination, RDCF75% + PHRD showed the highest plant height. The more number of leaves plant-1, number of branches plant-1, yield and yield parameters as compared to other treatments were also significantly influenced by application of PH. Combined application of 50% of RDCF+RS5 t /ha increased exchangeable soil K. PM3 t /ha+ RS5 t /ha+ PHRD conserved more organic carbon and total soil N. Results showed that the integrated use of PM, RS along with CF increased the availability of nutrients throughout the growth period by maintaining the long term productivity for sustainable production of tomato.
