ABSTRACT

Pigeon pea (Cajanus cajan (L) Millsp.) is an important pulse crop of India and it is extensively grown under rainfed conditions. Medium to long duration nature of the crop makes it more vulnerable to terminal moisture stress, especially that coinciding with the critical periods of growth. It is a short-day legume species, and the late maturing genotypes are more photosensitive than early types. Unfortunately, in spite of high importance of photo-insensitivity in super early and mid-early genotypes, availability of genotypes suitability to particular location is meagre. Plant density under rainfed conditions pronounces significant effect on pigeon pea performance under limited supplemental irrigation conditions. A field experiment entitled “Influence Of High Density Planting On Yield Parameters Of Super Early And Mid Early Varieties Of Redgram (Cajanus Cajan (L.) Millsp.)” was conducted during rabi, 2023 at wetland farm, S. V. Agricultural College, Tirupati with three different spacings with four varieties (super early and mid-early varieties) in factorial randomized block design and replicated thrice. The three different spacings viz., 30 cm × 15 cm, 45 cm × 15 cm and 60 cm × 15 cm, whereas the varieties chosen among super early varieties are ICPV 21111 and ICPV 21222, among mid early varieties PRG 176 and TS3R.
