A multi-location field experiment was conducted at 10 different locations of Punjab to study the response of pigeonpea varieties (AL 882 and PADT 16) to sowing dates (17 June, 24 June, 1 July and 8 July) at high plant density (33 plants/m[sup 2]). Results showed that days to 50% flowering and maturity decreased with delay in sowing at all the locations (Ludhiana, Ballowal Saunkhri, Gurdaspur, Bathinda, Abohar, Jalandhar, Faridkot, Patiala, Dyal Bharang and Sangrur). Plant height and pods/plant also decreased with delay in sowing. On mean basis, 24 June sowing recorded the highest grain yield (1941 kg/ha) followed by 17 June and 1 July sowings, which was 23.1, 17.4 and 16.7% higher over 8 July sowing, respectively. Early sown crop (17 June) accumulated higher heat units as compared to late sowings at all the locations. Variety AL 882 recorded higher plant height, pods/plant, 100-seed weight, biological yield and grain yield than PADT 16 and recorded 16.7% higher grain yield over PADT 16. However, PADT 16 variety was early in days to 50% flowering and maturity and accumulated less heat units than AL 882. Being determinate in nature, higher infestation of insect-pests was recorded in PADT 16 as compared to AL 882. It can be concluded that 24th June is the optimum sowing time of pigeonpea variety AL 882 at high plant density and it also provides high economic returns. [ABSTRACT FROM AUTHOR] |
