    Usefulness of sensory methods of analysis by a taste panel in differentiating the quality of cassava tubers under different manurial treatments
    (Kerala Agricultural University, 1975) Prema, L; Thomas, E J; Aiyer, R S
    Five kg. of cooked tubers from 4 treatment combinations from the two extreme levels of nitrogen and phosphorus in a fertiliser experiment conducted at Vellayani with 3 levels of nitogen (N0 = 0, N,-=75 N, = 150 kg P3O,,/ha) and 3 levels ofP

    Studies on the response N, P and K in conjunction with Ca on the growth and yield of tapioca (Manihot utilissima Pohl) var. malayan-4
    (Kerala Agricultural University, 1978) Gopalakrishna Pillai, K; George, C M
    A field experiment to study the response of three graded levels each of nitrogen (50, 100 and 150 kg N/ha), phosphorus (0, 50 and 100 kg P205/ha) potash (100, 150 and 200 kg K20/ha) in conjunction with calcium (0,600 and 1200 kg CaO/ha) on the growth and yield of tapioca var. "Malayan-4" grown in the acid red loam soils of the Agricultural College farm at Vellayani, Trivandrum has shown that the plant height, as well as weight of vegetative parts were generally increased by N and K; while branching of stems and number of tubers were increased by N and Ca application. Higher levels of N, K and Ca were instrumental for increased girth of tubers, while the tuber yield was increased by all the four elements. Application of 100 kg N, 50 kg P205 and 150 kg K20 in conjunction with 600 kg CaO per ha seems to be most promising for realising the maximum tuber yield of this variety of tapioca under the conditions of this experiment.

    Effect of levels and time of application of potash on growth and yield of tapioca
    (Kerala Agricultural University, 1978) Asokan, P K; Sreedharan, C
    A field experiment was conducted to study the effect of different levels and time of application of K in conjuction with farm yard manure in tapioca variety H—97. The results indicated that maximum tuber yield was obtained at 112.5 kg level of K. Three split application had given better response at lower levels of K. Farm yard manure application had given a better response at higher levels of K. Utilisation index showed a decrease after 75 kg level of K.

    Quality of tubers in tapioca (Manihot Utilissima Pohl) var malayan-4 as influenced by N, P, K and Ca fertilization
    (Kerala Agricultural University, 1978) Gopalakrishna Pillai, K; George, C M
    Field experiments and quality studies on tapioca variety 4/Malayan-4" study the effect of three graded levels each of nitrogen (50, 100 and 150 kg N per hectare), phosphorus (0, 50 and 100 kg P,0» per hectare), potash (100, 150 and 200 kg K2O per hectare) in conjunction with calcium (0, 600 and 1200 kg CaO per hectare) on the quality of tapioca tuber grown in the red loam soils of Agricultural College farm at Vellayani, Trivandrum have shown that application of higher levels of N beyond 100 kg/ha decreased the weight of edible fleshy portion of tubers, though it increased the protein content, dry matter as well as the starch content. Application of K increased the weight of edible portion, dry matter as well as starch content of tubers, though its application beyond 150 kg KjO/ha reduced the protein content. Application of moderate levels of 50 kg P: 05 and 600 kg CaO/ha also had some favourable influence on starch content, though they had very little effect on the protein content, as well as weight of edible fleshy portion of the tubers.

"Malayan-4" grown in the acid red loam soils of the Agricultural College farm at Vellayani, Trivandrum has shown that the plant height of vegetative parts were generally increased by N and K; while branching of stems and number of tubeis were increased by N and Ca application. Higher levels of N, K and Ca were instrumental for increased girth of tubers, while the tuber yield was increased by ail the four elements. Application of 100 kg N, 50 kg P20§ anc| 150 kg K20 in conjunction with 600 kg CaO per hectare seems to be most promising for realising the maximum tuber yield of this variety of tapioca under the conditions of this experiment.
