Abstract

An experiment was conducted at the orchard of Division of Fruit Science, SKUAST-J for the study of chemical control of black tip in mango cv. Dashehari. The trial was laid out in randomized block design with three replications. Five chemicals/antitranspirants viz., borex, washing soda, caustic soda, phenyl mercuric acetate (PMA) and kalonite were sprayed at different concentrations. The pooled data of two years revealed that the application of washing soda and caustic soda with 1.0 per cent concentration at flowering and fruiting stage significantly reduced the incidence of black tip as compared to control. Application of borex at 1.0 per cent significantly increased the fruit yield (15.42 kg/tree), fruit length (9.91 cm), fruit breadth (5.95 cm), fruit weight (153.79 g), fruit volume (151.99 cc), pulp weight (103.78 g), stone weight (28.55 g), flesh firmness (57.74 N) and TSS (17.57 %) in comparison to control.

Abstract

Pooled analysis of two-year data on nutrient status of 'Sardar' guava raised under organic manures and biofertilizers indicated that maximum leaf nitrogen (1.73%), phosphorus (0.24%), potassium (1.23%), calcium (1.96%), magnesium (0.80%); and maximum fruit nitrogen (1.12%), phosphorus (0.15%), potassium (0.94%), calcium (0.22%), magnesium (0.66%) was recorded, respectively, after fruit harvest with application of full dose of nitrogen to the plant applied through poultry manure augmented with Azotobacter and Azospirillium.

Abstract

The present study was conducted during 2013-14 to study the economics of different mulching materials viz., black polythene, white polythene, paddy straw, saw dust, sarkanda, dry grass and control (unmulched) on aonla under rainfed conditions of Jammu. The present investigation was carried out at Rainfed Research Sub-Station for Sub-tropical fruits Raya, of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu during 2013-14. The mean annual rainfall is about 1000-1200 mm. Soil of the experimental field was sandy clay in texture, having pH: 6.50, organic carbon: 0.50 per cent, available N: 174.50 kg/ha, available P: 15.80 kg/ha and available K: 140.00 kg/ha. Twenty eight trees were selected for the study and laid out inRandomized Block Experimental Design with one tree per treatment replicated four times. Application of treatments was done during the spring season viz., 19^th February, 2013.The study revealed that the total cost of cultivation was found to be higher (Rs. 2566.60) in black polythene mulch and white polythene mulches whereas it was minimum (Rs.2478.30) in control. Net returns were also recorded maximum (Rs. 2672.84/treatment) under black polythene mulch and minimum in control (Rs. 1559.30/treatment). However, benefit cost (B: C ratio) was also found to be maximum in black polythene mulch (1:2.04) and minimum in both white polythene mulch and control (1:1.69).

Abstract

A large number of citrus species are believed to have originated in India. In yesteryears, large numbers of citrus species are conserved in various institutes of the country for breeding programmer. Superior and elite materials are good sources for enhancing production and upgrading farmer’s income.
