Integrated Nutrient Management in Fruit Production

India has been bestowed with wide range of climate and physio-geographical conditions and as such is most suitable for growing various kinds of horticultural crops such as fruits, vegetables, flowers, nuts, spices and plantation crops (coco nut, cashew nut and cocoa). Its horticulture production has increased by 30 per cent in the last five years. This has placed India among the foremost countries in horticulture production, just behind China. During 2012-13, its contribution in the world production of fruits was 12.6 %. Total production of fruits during 2012-13 was 81.2 million tonnes (Anonymous, 2014). Though production of fruits has increased manifold over the last decade but there exists a gap between the demand and supply of fruits. The present fruit production in India meets only the 46% of the total demand. Thus there is strong need to increase the production and productivity through crop diversification and use of best horticultural techniques among which Integrated Nutrient Management is the one.

Effect of inorganic and organic fertilizers along with Azotobacter on growth, yield and quality of Kinnow mandarin

A study was conducted during 2013 and 2014 on the effect of integrated use of inorganic and organic fertilizers (vermicompost) along with bio-inoculants on plant growth, yield and quality of Kinnow mandarin. Vegetative growth parameters like plant height and canopy volume showed maximum increase with cent per cent nitrogen through urea augmented with Azotobacter. Replacing 25 per cent of nitrogen in the form of vermicompost resulted in maximum number of fruits, fruit weight, fruit volume, fruit length and width and fruit yield. TSS, Total sugars (reducing and non-reducing) and ascorbic acid contents of the fruits improved with the integrated application of vermicompost along with inorganic fertilizers and biofertilizers.

Cost and return analysis of different treatments of mulching and herbicide application on Peach (Prunus persica (L.) Batsch) cv. Shan-e-Punjab

The trees of peach cv. Shan-e-Punjab were treated with different orchard floor management practices (mulching and herbicidal treatment) in the month of February 2014. In all, there were 14 treatments including mulches viz., black polythene, paddy straw, saw dust, white polythene and herbicides viz., atrazine 50 WP (1.0, 1.5 and 2.0 Kg a.i. per hectare), oxyflurofen 23.5 EC (0.5, 0.75 and 1.0 l a.i. per ha) and pendimethalin 30 EC (1.0, 1.5 and 2.0 l a.i. per ha) and control which were replicated thrice. The total cost of cultivation per hectare was found to be highest (` 207480.00) in treatments T1 and T2 i.e. black polythene mulch and white polythene mulch, respectively whereas, it was found to be lowest of ` 185240.00 in the treatment (T14) i.e. control. Among all the treatments, the benefit: cost ratio was found highest with black polythene mulch (1:1.89) followed by atrazine 2.0 kg a.i/ha (1:1.86) and lowest in control (1:1.55). Thus, for improving growth, yield and fruit quality of peach cv Shan-e-Punjab, black polythene mulch and atrazine 2.0 kg a.i/ha are found to be most suitable and economically feasible under the Jammu subtropics.
