Item Production potential and economics on seven rice based crop rotations(Kerala Agricultural University, 1978) Balachandran Nair, G K; Sasidhar, V K; Santhakumari, GItem Relative efficiency of different herbicides on rice under semi dry conditions(Kerala Agricultural University, 1979) Balachandran Nair, G K; Balakrishna Pillai, P; Madhavan Nair, K P; Sasidhar, V KThe 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.Item Effect of split doses and times of nitrogen application on the content uptake and utilisation efficiency for direct sown rice in puddled soil(Kerala Agricultural University, 1977) Balachandran Nair, G K; Sreedharan, CA field experiment conducted to study the effect of split dose and times of N application on N uptake and utilisation efficiency showed ' that the skipping basal application of N and applying half at active tillering and the other luiif at panicle initiation stages gave maximum grain yield for direct sown rice in puddled soil. This was made possible by a higher total N uptake and a higher incremental N uptake contributting to grain yield.Item Yield potential of cowpea varieties(Kerala Agricultural University, 1981) George, K M; Balachandran Nair, G K; Sasidhar, V K
