Item Production potential and economics on seven rice based crop rotations(Kerala Agricultural University, 1978) Balachandran Nair, G K; Sasidhar, V K; Santhakumari, GItem Efficiency of complex fertiliser on rice(Kerala Agricultural University, 1979) Balakrishna Pillai, P; Sasidhar, V K; Vikraman Nair, RItem Response of sesamum variety Kayamkulam 1 to graded doses of phosphorus and potash in the red lom soils of Vellayani(Kerala Agricultural University, 1978) Sadanandan, N; Sasidhar, V KItem Crude protein content of guinea grass and component crops under different spacings(Kerala Agricultural University, 1979) Krishna Raj, P; Sadanandan, N; Nair, K P M; Sasidhar, V KItem Effect of split doses and time of nitrogen application on growth, yield attributes and yield of direct sown rice in puddled soil(Kerala Agricultural University, 1979) Balachandran Nair, C K; Sreedharan, C; Sasidhar, V KThe result showed that at harvest there was no significant difference between treatments suggesting that the plant height was made up by the nitrogen supplied at larer stages. The treatment receiving half nitrogen at active tillering and the other half at panicle initiation stage recorded the maximum panicles/m2. Nitrogen application at later stages especially giving half at panicle initiation has resulted in maximum panicle weight and 1000 grain weight. Skipping basal application of nitrogen and applying half at active tillering and the other half at panicle initiation stage has given the maximum grain yield of 4874 kg/ha.Item 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 Protein content of grain as affected by the application of urea and neam coated urea to rice variety – triveni(Kerala Agricultural University, 1974) Abraham, C; Sadanandan, N; Sasidhar, V KItem Performance of tapioca after cowpea in multiple cropping(Kerala Agricultural University, 1974) Sasidhar, V K; Sadanandan, NItem Effect of different levels of nitrogen and phosphorus on the uptake of phosphorus by rice variety - triveni(Kerala Agricultural University, 1974) Alexander, K M; Sadanandan, N; Sasidhar, V KA field experiment was undertaken during the third crop season of 1971 to study the effect of different levels of nitrogen and phosphorus on the uptake of phosphorus by the rice variety 'Triveni'. It was found that with increasing levels of nitrogen, the total uptake of phosphorus increased during all the growth stages of the crop. Similarly nitrogen phosphorus interaction significantly increased the phosphorus uptake at harvest. Different levels of phosphorus had no significant effect on the uptake of phosphorus during any of the growth stages of the crop.Item Study on the comparative performance of urea and neem coated urea on the yield and yield attributes of rice variety triveni(Kerala Agricultural University, 1975) Abraham, C; Sadanandan, N; Sasidhar, V KA field experiment to study the comparative performance of urea and neem coated urea on the yield and yield attributes of rice variety-Triveni was conducted at the College of Agriculture, Vellayani, Kerala during Virrippu season of 1973. The treatments consisted of four levels of nitrogen (0), 40, 80 and 120 kg N/ha) and five methods of applications ie. (1) full basal urea (2j full basal neem coated urea (3) 75% basa! urea -I- 25% urea as top dressing (4) 75% basal urea 4- 25% neem coated urea as top dressing, and (5) 75% basal neem coated urea + 25% neem coated urea as top dressing. It was found that the number of panicles per square meter, 1000 grain weight and yield of grain and straw were increased by nitrogen application. The application of 40 kg nitrogen as neem coated urea was found to be equivalent to 80 kg nitrogen as urea as far as the yield of grain was concerned. The results showed that rieem cake can be profitably used to increase the efficiency of urea applied to wet land rice.
