Appavu K.
Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore - 641 003, India
Field experiment was conducted on sandy loam soil to study the influence of different varieties of sesamum and N levels on yield and yield attribute's of sesamum at different stages of crop growth. Plant height was significantly influenced by the varieties and N levels. CO 1 sesamum significantly recorded the highest seed yield of 512 kg/ha while the variety TMV 6 recorded the highest oil content of 50.1 per cent. Oil yield was increased upto 36 kg N/ha only. Increasing N levels increased the crude protein content and CO 1 sesamum recorded the maximum crude protein content of 17.6 per cent.

Department of Agronomy, Tamil Nadu Agricultural University Coimbatore - 641 003, India
A field experiment was conducted during 1993 involving graded levels of nitrogen, FYM, lime,. neem coated urea (slow release fertiliser) and biofertiliser on carrot crop. The study revealed that nitrogen applied @ 240 kg ha −1 showed significantly highest N content in foliage (2.44%), root (1.52%) and nitrogen removal by foliage and root of carrot. A combination of FYM, lime, bio-fertiliser with 120 kg N ha −1 was found to be effective as compared to those applied individually.

Field experiments wefe conducted to evaluate the efficacy of Teprosyn (Zn and P) formlliations on the yield, growth and yield attributes of sunflower. The salient findings emanatted from the study are: Seed treatment with 130% Zn-P formulqtidn significantly increased the growth. yield and yield attributes of sunflower crop. Though this treatment maintained its superiority, it was on par with soil application of 5.5 kg Zn ha −1. The treatments exerted a non-significant influence on the P and Zn availability in post harvest soil. The Zn uptake by grain and straw of sunflower crop revealed a similar trend as that of yield and yield parameters.

An experiment was conducted during 1999–2000 to study the bio-efficacy of various chemical insecticides against aphid of “GCH-6” cotton (Gossypium hirsutum L) and their effect on ICBR. The results of eleven different insecticidal treatments showed that the treatments with imidacloprid 0.006 per cent, monocrotophos 0.04 per cent. endosulfan 0.07 per cent, dimethoate 0.03 per cent and methyl-o-demeton 0.025 per cent were found most effective for the control of A. gossypii on cotton under field condition. The maximum yield of seedcotton was recorded from the plots treated with endosulfan 0.07 per cent (1549 kg/hal. Treatment with monocrotophos 0.04 per cent was found most economical as it gave the highest cost benefit ratio (1 15.45) followed by methyl-o-demeton 0.025 per cent (1: 14.42), dimethoate 0.03 per cent (1: 14.39), phosphamidon 0.03 per cent (1: 13.73) and endosulfan 0.07 per cent (1: 11.14).

Rate of transmission of ToLCV by B. fabaci from tomato to tomato was 80–100 per cent when single whitefly was used per seedling and survived 24 h after inoculation. Female adults were found to be more efficient (86.66–100%) in transmitting ToLCV than males (26.66–33.33%) when single whitefly per seedling was used. Five adult whiteflies were required for 100 per cent transmission of ToLCV from tomato to tomato, when acquisition and inoculation access periods were 24 h each. The minimum acquisition access and inoculation access periods were 0.10 and 0.20 hours, respectively. A latent period of 6 h was necessary for B. fabaci to became viruliferous.

Forty five days old stecklings were transplanted on five dates of transplanting viz., 1 st October, 15 th October, 1 st November, 15 th November and 30 th November with four plant spacings viz., 60 x 60 cm, 60 x 45 cm, 60 x 30 cm and 60 x 15 cm were tested in seed crop of radish var. Pusa Chetki during rabi season of 2000–2001. The result indicated that maximum seed yield 17.49 q/ha was harvested from steckling planted on 1 st October. Among plant spacing, the closest spacing of 60 x 15 cm produced highest seed yield (17.96 q/ha). The interaction of time of planting x spacing was significant for number of pods per plant, seed yield per plant and per hectare, which indicated that 1 st October planting with close spacing 60 x 15 cm produced highest seed yield (25.59 q/ha).

An experiment was conducted to study the effect of postharvest fungicidal application on carotenoid development of Kesar mango fruits during storage period. For this purpose, fully matured Kesar mango fruits were subjected to the various treatments of waxol (6%l, waxol (6%) coupled with carbendazim (0.1%) and captan (0.2%). These treated and untreated fruits lot (as control) were kept for storage at room temperature (24.l8-30.57°C temp. with 47.50–74.00% RHl, cool chamber (21.36–23.l5°C temperature with 87.00–91.50% RH) and in cool storage (10°C temperature with 90.0–95.0% RH). It was observed that the fruits treated with waxol (6%) and either carbendazim (0.1.%) or captan (0.2%) successfully controlled the postharvest diseases of mango fruits. However, besides this, these fungicides were found to be beneficial in delaying the ripening process of mango fruits by slow development of carotenoid pigments.

The inbred lines and single cross hybrids (F' 1s), generated through a 12 x 12 diallel crossing system (12 inbreds of S 4/S 5 stage derived from divergent heterotic pools, viz., X 1W, X 2W and population 30) were evaluated in a randomized block design replicated thrice, under rainfed and irrigated conditions on clay loam and sandy loam soils. The estimates of variances suggested that all the traits under study were governed by additive (σ 2A), non-additive (σ 2D) and cytoplasmic (σ 2R) inheritance with predominant non-additive gene action. The higher GCA effects and per se performance revealed that inbreds P 1, P 2 and P 11 were good general combiners with good performance for grain yield and its various contributing traits, while higher estimates of heterobeltiosis, economic heterosis, SCA effects and per se performance revealedthathybrids(P 3 x P 4),(P 3 x P 7), (P 6 x P 8), (P 4 x P 11) and (P 7 x P 12) were superior for grain yield and various yield attributes.

The present study revealed that standard concentration(s) of culture filtrate of tested rhizospheric fungi has exhibited nematoxic effect by inhibiting the hatching of root-knot nematode, Meloidogyne incognita. The inhibitory effect of culture filtrate decreased with increase in the dilution and maximum hatching was found in S/1000 dilution but significantly less than that hatched in distilled water. Among the saprophytes, the minimum larvae were encountered by Aspergillus Candidus and A. nigerin all the dilutions of culture filtrate while among all the rhizospheric fungi, Verticillium albo-atrum showed maximum inhibitory effect on hatching.

Two hundred sorghum germplasm lines obtained from ICRISAT, Patancheru, Andhra Pradesh ( India) were evaluated against shootfly, Atherigona soccata Rondani during rabi 1993–94. From this germplasm, 18 lines were selected based on their performance against shootfly. During the next two consecutive years (rabi 1994–95 and 1995–96), the selected lines were again evaluated using fish meal technique. The results of the field screening over three years revealed that, the entries viz., IS-2191, IS-4481, IS-4516, IS-17596, IS-18366, IS33714, IS-33717, IS-33722, 1S-33740, IS-33742, IS-33756, IS-33761, IS-33764, IS-33810, IS-33820, IS-33839, IS-33843 and IS-33889 were identified as resistant to shootfly by recording 17.6, 16.9, 12.0, 15.7, 13.8, 18.0, 18.6, 12.7, 10.9, 15.7, 10.7, 10.8, 9.2, 17.1, 9.0, 13.5, 9.9 and 18.7 per cent deadhearts, respectively. These entries were statistically at par with the resistant check, IS-2312 that recorded 13.0 per cent deadhearts due to shootfly.

Field experiments were conducted with blackgram var. COBG 593 (in 2000) and TMV 1 (in 2001) at Alandurai and Mathuvarayapuram in a red sandy loam soil for assessing the efficacy of soil application and seed treatment by Zn, B, Sand Mo during 2000 and 2001. The results indicated that, soil application of 5 kg Zn + 1.5kg B + 0.5 kg Mo + 40 kg S ha −1 increased the yield of both the varieties and the yield increase was more with COBG 593 (34.1%) than TMV 1 (21%) indicating the high responsiveness of COBG 593 to added fertilisers. Soil application is found to be the best when compared to seed treatment of Zn, B, S and Mo. Similar trends of results were observed with nutrient availability and uptake.
