A field experiment was conducted during the rainy (kharif), winter (rabi) and summer seasons of 2020–21 and 2021–22 at the research farm of Indian Agricultural Research Institute, New Delhi to evaluate the productivity and profitability of pigeon pea–vegetable mustard–okra cropping system as influenced by enriched organic formulations. The experiment comprised of one cropping system (pigeon pea–vegetable mustard–okra) and seven nutrient sources viz., control, 100% RDN through FYM, 100% RDN through improved RRC, 100% RDN through PHA enriched FYM, 75% RDN through PHA enriched FYM, 100% RDN through PPC enriched FYM and 75% RDN through PPC enriched FYM were tested in randomized block design with three replications. Results showed that the apparent values of yield of the crops were influenced by enriched organic formulations during both the years. Among the treatments, application of 100% RDN through PHA enriched FYM gave significantly highest seed and stover yield, followed by 100% RDN through PPC enriched FYM and FYM during both the years of study. System productivity of cropping system in terms of pigeon pea-equivalent yield (PPEY) was significantly higher under 100% RDN through PHA enriched FYM (8.70 and 8.97 t ha-1) during both the years of experimentation. Results further revealed that the same treatment resulted into statistically highest system gross returns, net returns and B:C ratio (₹671.7 x103 ha-1 and ₹689.6 x103 ha-1; ₹553.6 x103 ha-1 and ₹567.8 x103 ha-1; 4.96 and 4.94 during 2020–21 and 2021–22, respectively) over other nutrient sources and remained at par with 100% RDN through PPC enriched FYM and FYM during both the years.
Experiments were conducted during three consecutive Kharif seasons to study the effect of commercially available insecticides formulations, Acetamaprid 20 % SP (1.0 gm/ litre of water), Imidacloprid 17.8 % SL (1.0 ml/ lit.), Quinalphos % 25 EC (2.0 ml/ lit.), Thiomethoxam 25 % WG (1.0 gm/ lit.), Neem oil 2% (20 ml/lit.), Karanj oil 2% (20 ml/lit.) against the White fly, Bemisia tabaci in Greengram. The descending order of most effective insecticides was: Imidacloprid >Thiomethoxam> Acetamaprid. The maximum population reduction over control was found after seven days of applying the second spray at 15 days of interval viz., 75.09 and 68.86 per cent due to Imidacloprid, Thiomethoxam, respectively the year 2015. A similar trend was found in the year 2016 and 2017. Thus, Imidacloprid 17.8 % SL was most effective against the White fly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae).
The sequential extraction of soil sulphur (S) species and their vertical distribution under continuous fertilization and intensive cropping in sandy clay loam soils were studied to understand the dynamics of soil S. The order of the species which was observed in different depths are as follows; Organic S > Heat soluble S > SO42- - S > Water soluble S and concentration has declined when increasing depths from surface to sub surface. The quantum of FYM applied in every year could build ups the sulphur in soil than mineral fertiliser alone. Irrespective of the nutrient management practices, 100% NPK + FYM @ 10 t ha-1 have significantly increased the sulphur and their fractions followed by 150 % NPK and 100% NPK + Zn treated plots. The lowest sulphur fractions were observed in control (T10) and recommended dose of fertiliser (-S free). When comparing the treatments, mineral fertilization plus FYM (10 t ha-1) shows the higher S than mineral fertiliser alone and depletion of S has noted in S free plot (DAP as P source) and absolute control.
In India, the arable lands are shrinking due to various developmental activities. There is no option other than bringing marginal and/or salt affected lands under cultivation and utilizing them judiciously for salt tolerant horticultural crops. An integrated approach of image interpretation coupled with field studies was followed in Bhilwara district of Rajasthan, to evaluate salt affected soils for pomegranate cultivation, where salt affected soils were scattered and occupied in 10.80% of total geographical area (TGA) of the district. It was comprised of saline, saline-sodic and sodic soils occupying 2.36, 5.67 and 2.79 percent area, respectively of TGA. Based on characteristics of saline and saline-sodic soils, they were assessed as marginally suitable for pomegranate cultivation due to the major limitation of salinity. The sodic soils are marginally suitable for pomegranate cultivation due to the limitation of high pH(pH 8.5 to 9.3) and its subsequent impact on nutrient availability. Limitations of correctable soil properties like pH, salinity or sodicity etc. can be improved after adding some suitable soil amendments and soil class may be upgraded. This will bring them to semi-prime agricultural land in future perspectives. Pomegranate produces fruits throughout the year in India due to suitable climatic conditions. The market of the Indian pomegranates is Europe (mainly Germany), Middle East and Asia. Mainly the products supplied to the markets in the month of December, January and March. In year 2018-19 the total export value of pomegranate was Rs.625.96 Crore, which is considered as a significant step in shining the Indian economy. Still, there is a good scope to increase farmer’s income by bringing marginal/salt affected soils under pomegranate cultivation.
Rapeseed-mustard contributes significantly to reducing oil consumption in the India and Rajastahn. Fertility control is required in most rapeseed-mustard-dominated locations in order to increase crop output. In this line, a field experiment was conducted on loamy sand soils at SKN Jobner (Rajasthan) by combining organic (biofertilizers) and inorganic plant nutrient sources to find out their effect on yield and yield attributes and economics return of taramira (Eruca sativa) under dryland conditions. This experiment was conducted from 2011 to 2013 in winter season and comprises the mean analysis. The experiment was laid out in a randomized block design comprised of eight treatments viz., control (no N & P2 O5), 50 % N and P2O5, 75 % N and P2O5, 100 % N and P2O5, Azotobactor + PSB seed treatment, Azotobactor + PSB seed treatment + 50 % N and P2O5, Azotobactor +PSB seed treatment +75 % N and P2O5, Azotobactor + PSB seed treatment +100 % N and P2O5. Application of 100 % RDF (N 30kg + 20kgP2O5 ha-1) + seed inoculation with Azotobacter + PSB significantly (p=0.05) increased number of primary and secondary branches plant-1, number of siliquae plant-1, test weight, seed yield, net returns (Rs. 25435 ha-1) and B: C ratio (4.02) over control. These research findings could be used to increase taramira production in dryland areas with low fertility of soil.
