Organic Carbon Storage

Soil organic carbon storage encompasses both soil productivity and environmental capabilities. The influence of fertilizer (nitrogen and phosphorus) levels (0 NP, 0·5 NP, 1·0 NP (recommended standard) or 1·5 NP) on total system productivity, sustainable yield index and soil organic carbon storage in Vertisols (Typic Haplustert) under groundnut and fallow-based cropping systems were examined in a field experiment over 6 years. The aim was to identify a system that provided an acceptable balance between total system productivity and soil organic carbon restoration. The experiment comprised two rainy season crops (groundnut or fallow) and five post-rainy season crops (wheat, mustard, chickpea, sunflower or summer groundnut), each post-rainy season crop with four levels of NP fertilizer. The total system productivity was 130% higher in the groundnut-based than in the fallow-based system and was in the order: groundnut–groundnut>groundnut–chickpea>groundnut–wheat>groundnut–mustard>groundnut–sunflower. The sustainable yield index was highest in the groundnut–groundnut system. The gross C input was relatively higher in the groundnut-based system but the C loss rate was greater. The amount of residue needed per ha per year to compensate for loss of soil organic carbon was estimated to be 4·3 t in the fallow-based and 7·6 t in the groundnut–based cropping system. Though the total system productivity was greater in groundnut–groundnut and groundnut–chickpea systems, soil organic carbon declined. The groundnut–wheat system contributed more C, particularly root biomass C, than other systems, improved the restoration of soil organic carbon and maintained total system productivity. It was concluded that current fertilizer recommendations are adequate for maintaining yields in groundnut-based systems but the addition of crop residues at regular intervals along with fertilizer is necessary to maintain restoration of soil organic carbon.

An investigation was carried out in the calcareous soil of Chapai Nawabganj belonging to the High Ganges River Floodplain during November 2008 to March 2009 to examine the effect of different macro and micronutrients (N, P, K, S, Zn, B and Mo at 150, 50, 100, 20, 3, 3 and 1 kg/ha, respectively) on the growth and yield of cabbage. Application of different nutrients exhibited significant influence on the growth and yield of cabbage. The highest plant spread (70.76 cm), height (37.89 cm), leaf length (37.83 cm), leaf breadth (27.13 cm), head thickness (12.85 cm), head diameter (23.02 cm), marketable head yield (76.53 t/ha) which is 191% increase over control), early head formation and maturity were recorded from the plot receiving N, P, K and B at the rate of 150, 50, 100 and 3 kg/ha, respectively. The treatment N, P, K and S showed the highest weight of loose leaves (640 g/plant) and decreased the weight of folded leaves or head weight, whereas, the treatment N, P, K and B increased the folded leaves or maximum head weight (1894.18 g/plant).  The Agriculturists 2014; 12(2) 24-33

The field experiments were conducted for one season rabi 2008-09 at the Multilocation testing site Magura on calcareous soil to study the effect of integrated nutrient management on the growth and yield of onion (cv. BARI piaj 2). The experiment was laid out in a RCB design. There were five treatments involving four inorganic levels and organic levels another absolute control (no manure and no NPK). Higher level of inorganic T1 i.e., (120-45-85-40 kg ha-1 NPK S+ 5 t/ha CD) produced significantly higher bulb yield (18.76 t/ha) which was on par with T4 (17.87 t/ha) i.e., 5 t/ha poultry manure + remaining amount from inorganic fertilizer T2. The results also indicated that the same treatments recorded the highest single bulb weight, bulb yield as well as gross returns and MBCR (7.14) as compared to other treatments.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22059 J.

Abstract We have evaluated eight different integrated crop management (ICM) modules for five years in a maize-wheat rotation (MWR); wherein, ICM1&2- ˈbusiness-as-usualˈ (conventional flatbed maize and wheat, ICM3&4- conventional raised bed (CTRB) maize and wheat without residues, ICM5&6- conservation agriculture (CA)-based zero till (ZT) flatbed maize and wheat with the residues, and ICM7&8- CA-based ZT raised bed maize and wheat with the residues. Results indicated that the ICM7&8 produced significantly (p<0.05) the highest maize grain yield (5 years av.) which was 7.8-21.3% greater than the ICM1-6. However, across years, the ICM5-8 gave statistically similar wheat grain yield, and was 8.4-11.5% greater than the ICM1-4. Similarly, the CA-based residue retained ICM5-8 modules had given 9.5-14.3% (5 years av.) greater system yields in terms of maize grain equivalents (MGEY) over the residue removed CT-based ICM1&4. System water productivity (SWP) was the highest with ICM5-8, being 10.3-17.8% higher than the ICM1-4. Nevertheless, the highest water use (TWU) was recorded in the CT flatbed (ICM1&2), ~7% more than the raised bed and ZT planted crops with or without the residues (ICM4-8). Furthermore, the ICM1-4 had produced 9.54% greater variable production costs compared to the ICM5-8, whereas, the ICM5-8 gave 24.3-27.4% additional returns than the ICM1-4. Also, different ICM modules caused significant (p<0.05) impacts on the soil properties, such as, organic carbon (SOC), microbial biomass carbon (SMBC), dehydrogenase (SDH), alkaline phosphatase (SAP) and urease (URE) activities. In 0.0-0.15 m soil profile, residue retained CA-based (ICM5-8) modules registered a 7.1-14.3% greater SOC and 10.2-17.3% SMBC than the ICM1-4. The sustainable yield index (SYI) of MWR was 13.4-18.6% greater under the ICM7&8 compared to the ICM1-4. Hence, this study conclude that the adoption of the CA-based residue retained ICMs in the MWR could sustain the crop yields, enhance farm profits, save water and improve soil properties of the north-western plan zones of India.
