Nutrient uptake and yield response of T. aman rice varieties as affected by planting treatments [in Bangladesh]
1992
Ahmed, M. | Rahman, S. | Bhuiyan, N.I.
A field experiment was conducted to study the performance of the nutrient uptake by Nizersail and BR-11 with 4 planting treatments, consisting of variable seedling age and time of planting. Seedling age more than 60 days transplanting later than September 3, decreased significantly the grain yields of both varieties. Transplanting on 18th September with 75 day-old seedlings gave reasonable grain yield of Nizersail as compared to negligible grain yield of BR-11. The concentrations of plant nutrients as three stage of crop growth of both the varieties were determined. The contents of N, P, K and Fe were maximum at 30 DAT and then showed progressive decline. Determination of sulfur and N:S ratio in the straw indicated that both the varieties suffered from inadequate supply of sulfur at 30 DAT and at harvest the ratios became similar and satisfactory. The nutrient concentrations in the straw was influenced very little by the planting treatments but higher uptake of nutrients by the plant tops at harvest occurred for the earlier two planting treatments than the latter ones.

1992
Dewindara Kaura. | Kapoor, A.C.
The nutrient profile and levels of antinutritional factors of five high yielding varieties of rice bean (Vigna umbellata) and one variety each of green gram and black gram were investigated. The proximate compositions of rice bean varieties did not vary significantly among themselves and were comparable with those of green gram and black gram, except for protein content, which was significantly lower in rice bean. However, the concentrations of riboflavin and ascorbic acid varied significantly among the rice bean varieties and were comparable with those of green gram and black gram. Amounts of unsaturated fatty acids were higher than saturated. There were some significant differences among the rice bean varieties in their total and extractable mineral contents, which were comparable with those of green gram and black gram, except for calcium, which was twice as great in rice bean than in black gram and green gram. The trypsin inhibitor activity and contents of phytic acid, polyphenolic compounds and saponins varied significantly.

Growth of five peanut varieties on the type A agroclimate in two clay soil textures
1992
Darmijati, S. | Muladi (Balai Penelitian Tanaman Pangan, Bogor (Indonesia). Kelompok Peneliti Fisiologi)
An experiment was carried out in a heavy clay soil from Lengkong, Sukabumi, West Java, from January to April 1990. Another experiment was carried out in light clay soil from Citayam, Bogor, West Java, from March to June 1990. Peanut varieties Gajah, Pelanduk, Banteng, Kelinci and Badak were used as sub plots, while the main plots were cow manure rates (0 and 5 t/ha). Inorganic fertilizers were used at the rate of 50 kg Urea, 250 kg TSP and 100 kg KCl/ha. respectively. The plot sizes were 3 m x 4 m and peanut seeds were dibbled at 40 cm x 10 cm spacing. Plant growth, yield component and yield of peanut on heavy clay (Lengkong) were poorer or lower than on light clay (Citayam). Plant growth, yield component and yield of Kelinci and Badak were better than varieties Gajah, Pelanduk and Banteng on light clay soil, however on heavy there were no differences among varieties. The P contents of peanut on heavy and light clay soil were not different. The nutrient uptakes of N, P and K in seed of peanut on heavy clay were lower than that on light clay. The nutrient uptake of N, P and K in seed of Kelinci and Badak was higher than that of Gajah, Pelanduk and Banteng.

Paisan Laosuwan | Nimitr Anuchan (Prince of Songkla Univ., Songkhla (Thailand))
Pot experiment was conducted to study the response of four recommended varieties of groundnut, namely Tainan 9, SK 38, Lampang and Khon Kaen 60-1 (Moket) to waterlogging. Waterlogging was found to adversely affect pod yield, yield components and other characters of groundnut. The effect of waterlogging on most characters including pod yield of all varieties was visible within two days after exposure to flooding. In terms of pod yield and seed size, Khon Kaen 60-1 tended to be more tolerant to waterlogging than Tainan 9. For all varieties, it was observed that, as the crop grew older, it became more susceptible to waterlogging. The adverse response of the legume to waterlogging was proposed to be due to the reduction of oxygen around the root zone as well as the reduction in nodulation and nutrient uptake.

1992
Chhipa, B.R. | Lal, P. (College of Agriculture, Johner (India))
A field study was conducted during the Rabi season of 1981-82 and 1982-83 to study the effect of graded levels of soil salinity (ECe 4.2, 8.1, 11.4, 15.2 and 18.1 dS/m) on the pattern of nutrient uptake by susceptible (Raj 911) and tolerant (Kharchia 65) variety of wheat. P and K content of grain and straw decreased while that of N, Ca and Na increased with increasing level of salinity. The magnitude of decrease or increase in the above nutrients was more in susceptible variety than that of tolerant one. Tolerant variety (Kharchia 65) accumulated higher quantity of N, K, P and Ca and restricted the uptake of Na as compared to susceptible variety (Raj 911) | [E' stato condotto uno studio in campo durante le stagioni Rabi del 1981-82 e 1982-83 per accertare l'effetto di livelli graduali di salinita' del suolo (ECe 4.2, 8.1, 11.4, 15.2 e 18.1 dS/m) sulle modalita' di assorbimento di nutrienti da parte della varieta' di grano suscettibile (Raj 911) e tollerante (Kharchia 65). I contenuti di P e K della granella e della paglia diminuivano mentre quelli di N, Ca e Na crescevano con l'aumento del livello di salinita'. La dimensione della diminuzione e dell'aumento nei nutrienti sopra citati e' stata maggiore nella varieta' suscettibile che in quella tollerante. La varieta' tollerante (Kharchia 65) ha accumulato una quantita' piu' elevata di N, P, K e Ca e ha diminuito l'assorbimento di Na se paragonato alla varieta' suscettibile (Raj 911)]

1992
Nowak, W.
In the years 1978-81 field and laboratory tests were carried out with 7 grass species. The grasses were sown out into bottomless pots. The pots were filled up with soil of 3 agronomic categories: light, medium and heavy, markedly differentiated in respect of mechanical composition, reaction and soil nutrient availability. The pots were burried in the ground and in principle supplied with the precipitation water only. The tests were done to compare the productive possibilities of particular species and varieties with 2 modes of utilization - pasture and cutting, as well as their fodder value and mineral composition
