A pot experiment was conducted at the Botany Department, A.M.U., Aligarh, on 2 root crop plants, viz. turnip (Brassica rapa L.), non-sugar-producing and sugar beet (Beta vulgaris L.), sugar-producing, to compare their physiological activity (Hill activity, photosynthesis and chlorophyll content). The seeds of each plant were sown in 20 pots (80% soil + 20% FYM) separately. Two samplings were done at 125 and 140 days (after sowing). Hill activity was measured spectrophotometrically using DCPIP indicator and photosynthesis was assayed by LICOR-6200 Photosynthesis System.

A field experiment was conducted on three better performing cultivars of rapeseed-mustard selected on the basis of seed yield and fatty acid composition of oil. The cultivars included two erucic acid free, viz. Brassica napus L. cv. Hyola PAC-401 and Brassica juncea L. Czern. & Coss. cv. TERI (OE) M21-Swarna and one locally popular high yielding, Brassica juncea L. Czern. & Coss. cv. Rohini as a check. These were grown with the five graded combinations of soil-applied N (urea) and P (diammonium phosphate), viz.

Abstract: An out door pot experiment was carried out to investigate the influence of salt stress on performance of four linseed (Linum usìtatìssìmum L.) genotypes namely, Laxmi-27, Parvati, Rashmi and Shubhra in terms of growth, carbonic anhydrase (CA: EC 4.2. 1.1) and Nitrate Reductase (NR: ECI 6.6. 1) activities, net photosynthetic rate (Pn), chlorophyll content, Electrolyte Leakage (EL), Leaf Relative Water Content (LRWC) and proline content, studied at 60 and 75 days after sowing and fibre content and yield parameters at harvest. .......

The feasibility of split (soil + foliar) applications of nitrogen (N) and phosphorus (P) and addition of a small quantity of sulfur (S) in the spray was tested for improving performance of rapeseed-mustard genotypes in a factorial randomized field experiment. Three genotypes (two erucic acid free, viz. Brassica napus L. cv. ‘Hyola PAC – 401’ andBrassica juncea L. Czern. and Coss. cv. ‘TERI (0E) M 21-Swarna’, and one best performing high yielding Brassica juncea L. cv.

Salt stress alters a wide array of plant metabolic mechanisms. Different strategies of the application of nutrients and phytohormones are required to overcome the adverse effects of salt stress. The main objective of the present study was to determine if added nitrogen (N) and gibberellin (GA3) in growth medium could alleviate the adverse effects of salt stress on plant metabolism.

Soil salinity is one of the major factors responsible for the low productivity of crop plants and has become an increasing threat for agriculture. In this context, the selection of tolerant genotype/s may be one of the remedies.

Hyacinth bean (Lablab purpureus L.) serves as a good source of vegetable proteins in human diet, and its seeds and pods contain as much as 20–28% protein. The bean contains tyrosinase enzyme, which has potential use for the treatment of hypertension. However, plant biological yield appears to be comparatively low in Aligarh soil in this region of India (Western Uttar Pradesh). A hypothesis was designed to address whether foliar application of triacontanol (TRIA) could enhance the crop productivity as well as crop quality.

Linseed (Linum usitatissimum L.) is an important oilseed and fibre crop. However, the production of linseed crop is unable to keep pace with the increasing demand of linseed products. Under these circumstances, the best strategy for dual-purpose linseed would be to increase the height of the plant and to improve seed weight, a task which may prove simpler than achieving the synchronization of seed and fibre maturity.
