Abstract:
An experiment was conducted during the year 2001 to 2014 at Cashew Research Station, Bapatla situated in southern coastal region of Andhra Pradesh. The experiment comprising of nine treatments with a objective to study the response of vegetatively propagated material of cashew to different doses of NPK fertilizers at different spacings with a variety BPP-8, developed at All India Coordinate Research Project on Cashew, Bapatla, Andhra Pradesh.
The results of the study revealed that among the treatments flowering duration was found lowest in the treatment S2M3 (96.7 days) followed by the treatment S3M1 (96.8 days) and highest flowering duration was recorded with the treatment S1M1 (104.0 days). Maximum number of mean flowering laterals per m2 was recorded in the treatment S2M3 (26.38) followed by the treatment S2M1 (26.31). Lowest number of flowering laterals per m2 was recorded in the treatment S3M3 (20.79). The maximum sex ratio (Male to Hermaphrodite flowers) was recorded in the treatment S2M1 is 0.148 followed by the treatment S1M3 (0.140). The lowest was recorded in S1M2 (0.096).
The mean number of nut per m2 was found highest in S1M2 (28.01) and followed by the treatment S2M2 (26.18). The lowest number of nuts per m2 was recorded with S1M1 (20.26). The maximum mean number of nuts/panicle was recorded with the treatment S1M2 (3.82) followed by the treatment S1M3 (3.51) and minimum was recorded in the treatment S1M1 (2.63). The mean nut weight was highest in the treatment S1M2 (7.56g) followed by S2M2 (7.13g) and lowest was recorded in the treatment S2M3 (6.93g). Mean apple weight was found highest in the treatment S3M1 (57.52g) followed by the treatment S2M2 (57.00g) and minimum was recorded with the treatment S3M2 (51.77g). The average nut yield per tree was highest with the treatment S1M1 is 7.73kg/tree followed by S1M2 (7.01kg/tree). The lowest yield was recorded with the treatment S2M3 i.e. 4.75kg/tree.
