Long Term Study

Soybean (Glycine max (L.) Merr.)–wheat (Triticum aestivum L.) is the dominant cropping system in the Vertisols of central India due to congenial climate, development of agro-industries, and export opportunities. Both are high-value crops, and raising them using organics may further improve produce quality and help in sustaining long-term productivity of the system. Information is lacking on how to sustain the system with the sole use of organics or biofertilisers in Vertisols. A long-term study was made during 1995–2002 at Indore, India, to evaluate the effectiveness of 3 organic manures [farmyard manure (FYM), poultry manure (PM) and vermicompost (VC) at varying rates] and biofertilisers (Azotobacter + phosphate solubilising bacteria) on productivity, grain quality, soil fertility, and profitability of a wheat–soybean cropping system. Grain yield of wheat was significantly increased with PM at 2.5–10 t/ha or FYM at 10–20 t/ha compared with the control. However, the highest productivity was obtained with PM at 10 t/ha, which even performed better than NPK, indicating that NPK fertilisers alone did not provide adequate and balanced nutrition for potential yield of the crop. Quality parameters of durum wheat, viz. protein content, hectolitre weight and sedimentation value, increased, while yellow berry content decreased significantly with PM at 2.5–10.0 t/ha compared with the control. Soybean yields were significantly influenced by the residual effect of organic manuring treatment applied to wheat. The treatment receiving PM at 10 t/ha produced the highest grain yield of wheat. However, this treatment could not produce a similar response in soybean yield due to production of excessive vegetative growth, adversely affecting grain yield. Superiority of PM over FYM, vermicompost and biofertilisers was evident in the overall profitability of the system. Various soil fertility parameters including chemical and biological properties showed conspicuous improvement over the initial status under the FYM and PM treatments. Microbial biomass C and activities of phosphatase and dehydrogenase were increased significantly with applications of manures. Sustainability yield index was maximum under PM at 5–10 t/ha, followed by NPK. Results suggested that application of PM at 5–10 t/ha to wheat was essential for improving productivity, grain quality, profitability, soil health, and sustainability of a wheat–soybean system.

The results on the effect of three decade long term application of chemical fertilizers and amendments on the yield of continuous maize-wheat crop rotation in an acid alfisol at Palampur revealed that continuous omission of essential nutrients in a maize-wheat sequence resulted in an appreciable decline in the grain yield of maize and wheat crops. A remarkable reduction in crop yield was noticed in plots where nitrogen was applied alone. Use of recommended level of N alone through urea had deleterious effect on crop productivity. The continuous exhaustionof native pools of K in 100% NP treated plots appreciably reduced percent grain yield. Application of farmyard manure (FYM) and lime along with NPK fertilizers increased the crop yield. The integrated use of optimal dose of NPK and FYM give better and more sustainable yields.

Soil fertility is fundamental in determining crop productivity and sustainability in farming systems. A long-term fertiliser experiment in Chinese double rice-cropping systems initiated in 2011 was used in this study to gain an insight into a complete estimating of soil fertility. The six fertiliser treatments included mineral fertiliser (NP, NK, and NPK), combined NPK with farmyard manure (NPKM) or crop straw (NPKS), and no fertiliser application as a control. Results showed that grain yield averaged 5.5–13.0 t/ha/year, and significant increasing trends were observed in the phosphorus-applied plots (NP, NPK, NPKM, and NPKS), but the treatments without phosphorus applied (control and NK) resulted in declining trends in both early- and late-rice yields. After long-term rice cultivation, the contents of total and available phosphorus significantly declined in phosphorus-deficient plots compared to other treatments. Regression analysis showed that the improvement in grain yields was positively correlated with the increased soil fertility over treatments. Relative to the NPK treatment, the NPKM treatment greatly enhanced soil fertility from 0.50 to 0.78, and particularly dramatically increased the content of available soil phosphorus. Therefore, the high grain yield and soil fertility can be simultaneously achieved by long-term balanced fertiliser applications in Chinese double rice-cropping systems.

A field study was conducted to analyze the effect of long term use of organic and inorganic fertilizers on productivity and soil fertility under paddy-sesame cropping system. Application of 100% NPK + secondary and micro-nutrients based on soil test (T7) showed significantly higher mean grain yield of paddy (4735 kg/ha) and sesame (460 kg/ha) and rice equivalent yield (5348 kg/ha) followed by application of 50% NPK + 50% N as Farmyard manure (FYM) + inorganic source of micronutrients as per soil test (T1). Whereas, application of 50% recommended dose of nitrogen (RDN) through FYM + bio-fertilizers for N + Recommended dose of phosphorus (RDP) through rock phosphate + phosphorus solubalizing bacteria (PSB) showed significantly least mean grain yield of paddy (3209 kg/ha) and sesame (314 kg/ha) and rice equivalent yield (3628 kg/ha). Further, among organic treatments (T2 to T6), higher mean grain yield of paddy (3834 kg/ha), sesame (326 kg/ha) and rice equivalent yield (4269 kg/ha) as compared to other treatments was recorded following the application of one third of RDN through FYM + one third of RDN through vermicompost + one third of RDN through neem cake + bio-fertilizers containing N and P carriers (T6). Whereas, higher nutrient status with respect to major and micronutrients and the improved soil fertility status was recorded in organic treatment plots. The application of nutrients through organic sources would improve the soil fertility status under paddy-sesame cropping system.

Balanced nutrient supply is important for the sustainable crop production. We evaluated the effects of nutrient management practices on soil properties and crop yields in rice (Oryza sativa L.) - rice - wheat (Triticum aestivum L.) system in a long-term experiment established at National Wheat Research Program (NWRP), Bhairahawa, Nepal. The experiment was designed as a randomized complete block experiment with nine treatments and three replications. Treatments were applied as: T1- no nutrients added, T2- N added; T3- N and P added; T4- N and K added; T5- NPK added at recommended rate for all crops. Similarly, T6- only N added in rice and NPK in wheat at recommended rate; T7- half N; T8- half NP of recommended rate for both crops; and T9- farmyard manure (FYM) @10 Mg ha-1 for all crops in rotation. Results of the study revealed that rice and wheat yields were significantly greater under FYM than all other treatments. Treatments that did not receive P (T2, T3, T7, T8) and K (T2, T4) had considerably low wheat yield than treatments that received NPK (T5) and FYM (T9). The FYM lowered soil pH and improved soil organic matter (SOM), total nitrogen (TN), available phosphorus (P), and exchangeable potassium (K) contents than other treatments. Management practices that ensure nutrient supply can increase crop yield and improve soil fertility status.Int. J. Appl. Sci. Biotechnol. Vol 5(1): 42-50

In southern and central India, farmers crop Vertisols only in the post-rainy season, to avoid land management problems in the rainy season. In 1983 ICRISAT established a long-term trial seeking to intensify cropping. The trial included intercrops, sequential crops and appropriate Vertisol management technology to allow consecutive rainy-season and post-rainy season crops to be grown. Benefits provided by legumes to succeeding rainy-season sorghum (Sorghum bicolor) were analysed in relation to a non-legume system of sorghum + safflower (Carthamus tinctorius). Rainy-season sorghum grain yield production was sustained at about 2.7 t ha−1 over 12 years within a continuous sorghum–pigeonpea (Cajanus cajan) intercrop system. With a cowpea–pigeonpea intercrop system, succeeding sorghum benefitted each year by about 40 kg N ha−1 (fertilizer nitrogen (N) equivalent). Without N fertilizer application the sorghum grain yield was around 3.3 t ha−1. Legume benefits were less marked in the chickpea (Cicer arietinum)-based rotation than in the pigeonpea system, in which a 12-year build up of soil total N (about 125 μg g−1) was observed. Although sorghum benefitted from this system, pigeonpea yields declined over time due to soil-borne fungi and nematodes. Wider rotations of crops with pigeonpea may help to overcome these problems, while sustaining sorghum production.

Cultivation of green manure (GM) crops in intensive cropping systems is important for enhancing crop productivity through soil quality improvement. We investigated yield sustainability, nutrient stocks, nutrient balances and enzyme activities affected by different long-term (1982–2016) green manure rotations in acidic paddy soil in a double-rice cropping system. We selected four treatments from a long-term experiment, including (1) rice-rice-winter fallow as a control treatment (R-R-F), (2) rice-rice-milkvetch (R-R-M), (3) rice-rice-rapeseed (R-R-R), and (4) rice-rice-ryegrass (R-R-G). The results showed that different GM rotations increased grain yield and the sustainable yield index compared with those of the R-R-F treatment. Compared with those of R-R-F, the average grain yield of early rice in R-R-M, R-R-R, and R-R-G increased by 45%, 29%, and 27%, respectively and that of late rice increased by 46%, 28%, and 26%, respectively. Over the years, grain yield increased in all treatments except R-R-F. Green manure also improved the soil chemical properties (SOM and total and available N and P), except soil pH, compared to those of the control treatment. During the 1983–1990 cultivation period, the soil pH of the R-R-M treatment was lower than that of the R-R-F treatment. The addition of green manure did not mitigate the soil acidification caused by the use of inorganic fertilizers. The soil organic matter (SOM), total nitrogen (TN) and total phosphorus (TP) contents and stocks of C, N and P increased over the years. Furthermore, GM significantly increased phosphatase and urease activities and decreased the apparent N and P balances compared with those in the winter fallow treatment. Variance partitioning analysis revealed that soil properties, cropping systems, and climatic factors significantly influenced annual grain yield. Aggregated boosted tree (ABT) analysis quantified the relative influences of the different soil properties on annual grain yield and showed that the relative influences of TN content, SOM, pH, and TP content on annual crop yield were 27.8%, 25.7%, 22.9%, and 20.7%, respectively. In conclusion, GM rotation is beneficial for sustaining high crop yields by improving soil biochemical properties and reducing N and P balances in acidic soil under double- rice cropping systems.
