    (Kerala Agricultural University, 1979) Balachandran Nair, G K; Balakrishna Pillai, P; Madhavan Nair, K P; Sasidhar, V K
    The findings of the present investigation reveal that amongst different weed control measures tried the application of propanil (Stam F — 34) in combination with 2, 4 — D (Feronoxone) at the rate of 0.75 and 0.5 kg. a. i/ha respectively, followed by propanil (Stam F — 34) alone at the rate of 1.5 kg. a.i/ha and Butachlor (Machete) alone at the rate of 1.5kg. a.i/ha are beneficial in controlling weeds and improving grain yields of rice.

    Effect of N and K in coleus
    (Kerala Agricultural University, 1993) Geetha, K; Madhavan Nair, K P
    The effect of N and K and their lime of application in coleus revealed that N at the rate of 60 kg/ha was sufficient to produce higher tuber yield, high dry matter yield, maximum bulking rate and maximum utilisation index. Highest yield of tuber and highest dry matter yield per ha were obtained at the rate of 120kg foO/ha. Split application of nutrients was found to be the best method for obtaining higher weight of marketable tubers, higher tuber yield per plant, maximum dry matter yield and highest tuber yield.
