STUDIES ON THE EFFECT OF NPK ON THE GROWTH, YIELD, AND QUALITY OF NEW CASTLE APRICOT
The Himalayan region ranging from 3000 to 5000 ft. above sea level is ideally suited for the cultivation of apricots. During the past decade, lot of area has been planted with apricots particularly under New Castle, Kaisha and Shipley's Early varieties. However, much scientific information is not available regarding the cultural aspects of this fruit based on work done in our country or elsewhere. Keeping the dire need for such work, various trials on apricot were started at the Regional Fruit Research Sub-Station at Kandaghat established during 1956. On the basis of work done at the station, the authors earlier reported the results of a fertilizer experiment carried out on 12-years-old trees of New Castle apricot (Chadha and Bajwa3). It was therein reported that nitrogenous fertilizers in combination with phosphorus and potash significantly increased the growth of apricot. The yield was not affected during the first three years of trials, though the effects of nitrogenous fertilizers became clear in the fourth year. The present paper reports results of another experiment conducted under the aegis of the Indian Council of Agricultural Research at the same station on newly planted plants of New Castle Apricot.
