Continuous application of chemical fertilizers alters the soil biological properties and in situ causes residual effect on the crop plants. Field experiments were conducted with microbial inoculants and reduced inorganic fertilizers. The results of the experiments showed that application of 50 % recommended dose of nitrogen (N), phosphorous (P) and potassium (K) + azolla+ azophos + K releasing bacteria (KRB) + zinc solubilizing bacteria (ZSB) was found to have maximum soil microbial population viz., azospirillum (5.4 MPN/g), phosphobacteria (54 x 104 cfu/g) and diazotrophs (56 x104 cfu/g) under system of rice intensification (SRI) ecosystem, while 25 % recommended dose of NPK + azolla + azophos + KRB + ZSB was found to have maximum soil alkaline phosphatase (538 µg of P nitrophenol/g/h), acid phosphatase (248 µg of P nitrophenol/g/h), urease (79 µg of NH4/g/24 hrs) and dehydrogenase (110 µg of TPF/g/24 h) enzyme activity under SRI ecosystem. Among the treatments, maximum N (357 kg/ha), P (93 kg/ha), K (315 kg/ha) and yield (6800 kg/ha) was found in the treatment 100% recommended dose of NPK which was found to be on par with the yield (6850 kg/ha) under 50% recommended dose of NPK + azolla+ azophos + KRB + ZSB under SRI ecosystem.

Field experiments were conducted at experimental farm, Faculty of Agriculture, Annamalai University, Chidambaram during July to September (2008) and January to March (2009) in two seasons to study the effect of foliar spray of Panchagavya on the growth and yield of Baby corn cv. COBC 1. The experiments were laid out in Randomized Block Design with fourteen treatments and replicated thrice. The treatments included foliar spray and inorganic nutrient application at various stages of baby corn. The results revealed that application of 100% recommended dose of fertilizers (RDF) [N150: P60 (P2O5): K40 (K2O)] and 4 sprays (15, 25, 35 and 45 DAS) of 3 % Panchagavya recorded the highest growth attributes and yield of fresh Baby corn and this was followed by application of recommended dose of fertilizers (100 %) along with 3 sprays (15, 25 and 35 DAS) of 3 % panchagavya during both the seasons. The least growth and yield parameter were recorded in 3 sprays of 4 % Panchagavya without use of inorganic fertilizers. The increase in growth and yield of baby corn was mainly attributed by greater availability of nutrients through soil application (100 % RDF) and foliar spray of panchagavya at various stages of crop growth.

The present investigation was conducted on 6 years old kiwifruit vines cultivar ‘Allison’ at a spacing of 4.0 m × 6.0 m for two consecutive years 2018-19 and 2019-20 at experimental block of Department of Fruit Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP). The experiment was laid out in triplicate in Randomized Block Design with 8 treatments under three farming systems viz., Inorganic Fertilizer Based System (IFBS), Organic Farming Based System (OFBS) and Subhash Palekar’s Natural Farming System (SPNFS). The maximum leaf area (158.1 cm2), leaf area index (4.36), chlorophyll index (51.2), comparative photosynthetically active radiation (612 µ mol quanta m-2 s-1) was found in the treatment (T8) receiving 30 liters of jeevaamrit (JM) + 3 kg ghana jeevaamrit and 40 kg FYM per vine under SPNFS. Among OFBS, the treatment T2 (100% recommended dose of nitrogen (RDN) through vermicompost and poultry manure on 50:50 basis) observed maximum leaf area (151.8 cm2), leaf area index (4.35), comparative photosynthetically active radiation (642 µ mol quanta m-2 s-1) but lower significantly lower chlorophyll index (51.2) over T1 (Recommended dose of inorganic fertilizers + FYM) treatment of IFBS. Hence application of 30 litres jeevaamrit and 3 kg ghana jeevaamrit (both in 3 equal splits first in end of January, second in February and third in the month of April) along with 40 kg FYM per vine or alternatively substitution of 100% RDN through vermicompost and poultry manure on 50:50 basis along with 40 kg FYM were found to be best and alternate different option in place of inorganic fertilizers to ‘Allison’ cultivar of kiwifruit under mid-hill conditions of Himachal Pradesh, India. Furthermore, the research emphases mainly on improving soil health without compromising growth and yield of kiwifruits in the region. By using alternative sources of nutrients, farmers can obtain the comparable growth and yield of kiwifruits.

Plant growth promoting rhizobacteria (PGPR) are capable to reduce the use of chemical fertilizers input cost of farmer. Keeping in view the study was designed to investigate and evaluate inoculation effect of indigenous rhizospheric bacteria on growth and yield of wheat (Triticum aestivum L.) under in vitro and in vivo conditions using different treatments. Ten potential strains were selected on the basis of their ACC deaminase activity, siderophore production, P-solubilization and production of indole acetic acid (IAA). Further these strains were tested in three different experiments (growth chamber, pot and field). We found significant increase in crop growth response to the inoculants in comparison with un-inoculated control. In pot and field trial we tested PGPR with recommended dose of inorganic fertilizers. The results of present study revealed that inoculation of bacterial strains with wheat seeds significantly increased plant growth and improved crop yield. Results of present study reveal that these strains could be employed in different combinations and can get higher yield in case of half recommended doses of inorganic fertilizers along with consortium of strains in comparison with sole application of recommended dose of fertilizer and with consortium of strains. These strains were further identified by 16Sr RNA gene sequencing, fatty acid profile and biolog. It can be concluded that inoculated bacteria have more potential and contributes in good crop quality, increased yield when they are applied in combination, thus have potential to minimize use of chemical fertilizers.

The present study aimed to the effect of different organic manures on the growth and yield attributes of cotton by conducting field experiments during rice fallow season of 2013-14 and 2014-15 at the Tamil Nadu Rice Research Institute, Aduthurai.. The cotton growth parameters such as plant height, leaf area index, dry matter production and monopodial branches plant-1 were significantly influenced by the application of 100% recommended dose of fertilizer through vermicompost (on equal N basis). Also application of recommended dose of fertilizer through vermicompost (on equal N basis) recorded significantly higher yield attributes viz., sympodial branches plant-1, number of bolls plant-1, boll weight and seed cotton yield (17.4 and 18.6 q ha-1 during both the years, respectively). Economic analysis also indicated that Insitu vermicomposting produced higher net returns with higher B:C ratio.

Rice Yields

The decline in rice yields as a result of excessive chemical fertilizer (CF) inputs is a matter of great concern in rice-growing regions of Asia. In two-year’s field experiments, the nitrogen, phosphorus, and potassium (NPK) status, growth characteristics and yield of rice were examined by application of poultry manure (PM), cow manure (CM) and compost (CP). Organic fertilizers were applied as EMN (estimated mineralizable N) based on their total N content. Six treatments were assigned in a randomized complete block design: (1) no-N fertilizer (N0); (2) 50% CF (CF50), (3) 100% CF (CF100); 50% CF + 50% EMN from (4) PM or (5) CM or (6) CP. Compared with CF100, the CF50PM50 (total N ≥ 4%) accumulated higher N, P and K content in leaf, sheath, panicle and seeds, resulting in greater growth and yield. The CF50PM50 increased yield by 8.69% and 9.70%, dry matter by 4.76% and 5.27% over CF100 in both years. The continuous application of CF50CM50 (total N < 4%) and CF50CP50 (total N < 4%) treatments led to similar NPK contents but higher yields than those of CF100 treatment in 2018. In conclusion, the organic fertilizer (total N ≥ 4%) with the EMN method enhances higher N availability in each year. Continuous application of organic fertilizer (total N < 4%) over two years effectively increased N availability in the second year. The 50% organic fertilizer (total N ≥ 4%) and 50% CF led to increased NPK availability and rice yields over the 100% CF treatment, reducing CF usage and leading for sustainable agriculture.

Field experiments were conducted on Alfisols in Nigeria between 1991 and 1993 to determine the residual effect of maize (Zea mays) and cowpea (Vigna unguiculata) on the growth, pod yield and N response of a succeeding okra (Abelmoschus esculentus) crop. Cowpea and maize were grown alone with 30 and 60 kg/ha of N, P and K, respectively, or intercropped with 60 kg/ha as a basal dressing. The preceding crops had a significant effect on soil nutrient changes, okra growth and yield, and N response of okra. Cowpea increased the N, P and K status of the soil in both sole and mixed stands, compared with sole maize. Leaf area, pod weight and marketable pod yield of okra after sole cowpea or the maize/cowpea intercrop were all significantly higher than after sole maize. Although the application of nitrogen to succeeding okra promoted growth and increased pod yield, this was not accompanied by an increase in the pod yield of okra after sole cowpea or the maize/cowpea treatment beyond 45 kg N/ha. The beneficial effects of the preceding maize/cowpea intercrop on soil fertility, okra pod yield and amounts of N required for okra were partly due to the higher rate of basal nutrients applied as compared to the effects following sole cowpea.

A field experiment was conducted at Research farm of Bihar Agricultural University, Sabour (longitude 87o2’42”East and latitude 25o15?40? North at an altitude of 46 meters above mean sea level) with Katarni rice cv Bhagalpur Katarni during kharif season of 2017. The experiment with ten treatments was laid out in Randomized  block design (RBD)  with three  replications. Results revealed that among all the applied organic treatments the maximum microbial population viz., Bacteria, Actinomycetes, Fungi, Azospirillum, PSB and KSB (71.66, 27.33,  57.66, 43.66, 63.00 and 47.66 cfu × 105 g-1 oven dry soil) were recorded with the application of treatment T5 {(75 % N (FYM) basal + 25 % N (V/C) at 25 DAT + Azospirillum  @ 5 kg ha-1  + PSB @ 5 kg ha-1 + KSB @ 5 kg ha-1)} at panicle initiation stage  and similar trend were obtained at harvesting stage. Application of the same treatment significantly increased dehydrogenase activity by 81.62%, 10.80%, 24.86%, 15.66%, 17.83% and 18.91% when compared with application of T1 (RDF), T3 {(100 % N FYM) as basal)}, T7 {(100 % N (GM)}, T8 {(50 % N (GM) + 50 % N (V/C) at 25 DAT)}, T9 {(75 % N (GM) + 25 % N (V/C) at 25 DAT + Azospirillum @ 5 kg ha-1 + PSB @ 5 kg ha-1 + KSB @ 5 kg ha-1)} and  T10 {(75 % N (GM) + 25 % N (V/C) at 25 DAT + Panchagavya on foliar application )}, respectively. Among all organic treatments the maximum grain yield of paddy (27.39 q ha-1) was recorded in treatment T5 {(75 % N (FYM) basal + 25 % N (V/C) at 25 DAT + Azospirillum  @ 5 kg ha-1  + PSB @ 5 kg ha-1 + KSB @ 5 kg ha-1)}. Among all the organic inputs and microbial inoculants, the combined application of 75 % N (FYM) basal + 25 % N (V/C) at 25 DAT + Azospirillum @ 5 kg ha-1 + PSB @ 5 kg ha-1 + KSB @ 5 kg ha-1 was found to be effective in modifying the soil microbial population and microbial community structure and grain yield of scented rice.

Pot and field experiments were conducted to investigate the residual phytotoxicity of 2,4-D to wheat (Triticum aestivum) and barley (Hordeum vulgare) on alkaline clay soils in southern Queensland during winter. Effects of soil moisture, 2,4-D formulation, application rate, crop species and cultivar were investigated. With the exception of a 4% reduction in wheat grain yield in 1 field trial (considered commercially acceptable), grain yields of wheat and barley were not affected when seed was sown within 2 h of field application of 2,4-D dimethylamine or ethyl ester at rates of application up to 1 kg/ha. No significant reduction in phytotoxicity (measured by shoot dry matter reduction of wheat) of 2,4-D dimethylamine occurred when exposed on dry soil for 4 weeks in pots, or of ethyl ester or dimethyl amine exposed for 16 days on dry soil in the field. In moist soil in pots, loss of phytotoxicity to wheat of 2,4-D dimethyl amine was complete within 4 weeks when the herbicide was applied at 2 kg/ha or 2 weeks when applied at 0.5 kg/ha.
