Abstract

Grape (Vitis vinifera L.), belonging to Vitaceae family, is considered to be one the important fruit. Besides being delicious, it is also nutritious as it is enriched with vitamins and minerals. The matter of concern related to grape cultivation in Jammu & Kashmir is its declining productivity and also the degrading quality of the produce when compared to other major producing states of the country. The possible reason for declining productivity is the unscientific approach and inappropriate cultural practices followed by growers in its cultivation. The knowledge regarding the fertilizer requirement and the optimum budload in grapes is also limited in the valley. Thus there is the need for focusing on appropriate cultural practices so as to achieve higher quality production and also increase the productivity of grapes. Bud load and fertilizer scheduling also effect the percentage of shot berries (smaller and shrivelled berries). Thus with the objective of giving proper recommendation t

Conclusion

Thus from the present investigation, it is clearly seen adequate bud load and fertilizer dosage has a significant effect on the percentage of shot berries as well as the sweetness index (TSS /Acid ratio) of the berries. Maintaining the budload @ ‘128 buds/vine-16 canes with 8 buds on each cane’ and applying the fertilizer dose @ ‘FYM-50 kg/vine + 2 times recommended dose-NPK: 1110, 454, 940 g/vine’ were found to be most effective in improving berry characteristics and decreasing the percentage of shot berries in grape cv. Sahebi. Further researches still needs to be conducted which focus on the scope of fertigation in high density grape orchards and organic fruit production. The comparison between the fertilizer efficacy through direct application and fertigation also needs to be assessed in future.
