    ABSTRACT: Farming with natural rocks and minerals was an age-old practice. Intensive agriculture with imbalanced fertil-izer usage has led to a decline in soil quality and so, restoring this soil degradation needs urgent attention. In this context, farming with natural minerals (zeolites) has drawn attention. Zeolites are natural aluminosilicates present as rocks in different parts of the world. However, they are also inherently present in Vertisols mixed with soils. Ex-clusive use of zeolites has gained a new momentum in the recent past owing to multitude of benefits accrued from them. Japanese farmers were pioneering workers on zeolite usage to manage soil moisture and reaction. Their ion-exchange capacity is helpful for plant nutrition as well as soil amendment; besides the recent research on zeolite-herbicides interactions is encouraging. Although considerable research on zeolites in agriculture has been advanced, further research need to be carried out for their efficient utilization in farming.

    ABSTRACT: A field experiment was conducted at Varanasi during the two consecutive pre-kharif season of 2012 and 2013 to work out the optimum levels of NPKS and Zn application for maximizing the yield, monetary return and nutrient use efficiency of baby corn. Results revealed that baby cob, baby corn and green fodder yield, economics and nutrient uptake (N, P, K, S and Zn) were recorded significantly higher with application of 125% RDF. Further, application of 50 kg S/ha resulted in significant increase of baby cob, baby corn, green fodder yield, net profit and nutrient uptake (N, P, K, S and Zn) over control but it remained at par with 25 kg S/ha. Similar trend were observed with application of zinc levels also. Increasing levels of sulphur and zinc application progressively reduced agronomic and physiological efficiency and apparent recovery of baby corn. In general, these indices were noted markedly higher with application of 25 kg S/ha and 5 kg Zn/ha over 50 kg S/ha and 10 kg Zn/ha, respectively. However, nutrient harvest index of N, P, K, S, Zn were increased gradually with application of increasing levels of NPKS and Zn. Hence, application of 125% RDF along with 50 kg S/ha and 10 kg Zn/ha was found optimum to obtain the maximum baby corn yield, net profit and nutrient use efficiency under irrigated condition of Varanasi.

    ABSTRACT: In order to evaluate the best management practices i.e. mulching, liming and farm yard manures for maximizing the productivity, profitability, nutrient uptake and quality on winter maize, a field experiment was conducted during the two consecutive rabi season of 2010-11 and 2011-12 at Agricultural Research farm of ICAR, RC for NEH Region, Nagaland Centre Jharnapani, Medziphema.Experiment was laid out in a split-split plot design having 24 treatment combinations of mulching and lime along with farm yard manures and replicated thrice. Results revealed that application of straw mulches significantly increased all the growth and yield attributes, grain yield, protein content and nutrient uptake by maize. Among the levels of lime, higher grain yield (3.91 t/ha) and stover yield (4.24 t/ha) were noted with application of lime @ 0.6 t/ha. Similarly, significantly higher grain (3.79 t/ha) and stover yield (4.17 t/ha), nutrient uptake, protein yield were recorded with application of farm yard manures @ 12 t/ha. Application of straw mulch along with 0.6 t/ha lime and FYM @ 12 t/ha was recorded markedly higher total rainfall and effective rainfall use efficiency. Hence, straw mulching applied with 0.6 t/ha furrows lime and 12 t FYM/ha should be adopted to obtain the maximum grain yield, net profit and nutrient uptake by winter maize.

    ABSTRACT: A field experiment comprising varying levels of sulphur (0, 20 and 40 kg S/ha) applied through different sources (ammonium sulphate, single super phosphate, gypsum and elemental sulphur) was conducted on loamy sand soil at Ludhiana, Punjab during spring seasons of 2008 and 2009 to identify the optimum dose and better source of sulphur for higher sunflower productivity. Significant improvement in seed yield of sunflower was observed with each incremental dose of sulphur up to 40 kg S/ha with 6.9–9.0% yield superiority over control. The application of graded doses of sulphur at the rates of 20 and 40 kg S/ha through gypsum increased the seed yield over control by 8.6 and 10.7%, respectively, whereas the corresponding increases were 8.5 and 10.4% for ammonium sulphate, 5.4 and 7.3% for single super phosphate and 4.9 and 7.5% for elemental sulphur at the respective levels of sulphur nutrition. Highest seed yield (2.66 t/ha), oil content (42.9%), net returns ( 46.3 × 103/ha) and B:C ratio (4.08) was recorded with application of 40 kg S/ha applied through gypsum. Positive and highly significant correlation was observed between seed yield and head diameter (r=0.977**), dry matter accumulation (r=0.935), seed weight (r=0.810**). Oil content in the seed recorded a positive and highly significant relationship with uptake of N (r=0.984**), P (r=0.993**) and S (r=0.978**), signifying the importance of balanced nutrition in improving the oil content. Almost similar seed yield can be obtained with economic optimum dose of sulphur, indicating the saving of S ranging from 0.4 to 6.6 kg/ha depending upon the source.

    ABSTRACT: The introduction and subsequent rapid adoption of Bt. transgenic cotton hybrids (Gossypium species) have undoubtedly been the most significant event in the history of cotton in India. Besides providing resistance against lepidopteron pests, the Bt. hybrids matured earlier, were more determinate, had a rapid leaf area development, retained more early set fruiting forms and perhaps have a shallower root system. Both researchers and farmers during the last decade have been fine-tuning the agronomy to maximize the benefits from Bt cotton. ...

    ABSTRACT: The present work carried during 2010–12 at the Dharwad, Karnataka, to provide support to the farmers of selected zones in decision-making process towards application of fertilizer in selected crops. A Decision Support System (DSS) on fertilizer recommendation was designed and developed using Visual Basic 6.0 as a plat-form taking help of the information from Soil Test and Crop Response (STCR) research. The developed DSS is a console application and helps in taking decision to farmers on amount of fertilizer to be applied in different crops. The study revealed that, on an average framers of Dharwad, growing maize (Zea mays L.) and chilli (Capsicum sp.) are applying 20 kg N, 10 kg P2O5, 12 kg K2O and 26 kg N, 36 kg P2O5, 15 kg K2O/ha for each crop in excess of the required amount which caused not only unnecessary expenditure on fertilizer, amounting to 938 and 2,102/ha respectively, Thus, the developed DSS is useful in augmenting economic agricultural production maintaining soil and environmental health, avoiding unnecessary wastage of resources, even in absence of experts by the farmers themselves.
