“…Reduction in plant height may be due to lower turgor pressure and diminished cell division on account of water deficit stress (Ogbonnaya et al, 2003). Similar results have been found by Kazi et al (2002). From the results the tallest and shortest plants were observed when combined organic fertilizers (zeocompost + vermicompost, zeocompost + Z-ACM and zeocompost + Z-ACM) and combine chemical treatments (urea and urea + cattle manure) were applied, respectively (Table 6).…”

The main objectives of this research were to determine the effects of applying organic and chemical fertilizers under different irrigation regimes on sunflower (Helianthus annuus L.) morphological traits, yield components, grain yield and grain quality. The experiment was conducted as spilt plots based on a randomized complete block design with three replicates. Irrigation treatments at three levels (well-irrigated, mild and severe drought stress) were allocated to main plots and eight fertilizer treatments (urea (F1), urea + composted cattle manure (F2), zeocompost (F3), vermicompost (F4), zeolite-amended chicken manure (Z-ACM) (F5), zeocompost + vermicompost (F6), zeocompost + Z-ACM (F7) and vermicompost + Z-ACM (F8)) were randomized in sub-plots. The results showed that irrespective of the drought stress intensity, organic fertilizer treatments produced more dry matter, heavier and greater grain than did chemical treatments. In well-irrigated plots, the highest grain yield was obtained from F6, F7 and F8 treatments. Under drought stress conditions, the highest grain yield was obtained from the high zeolite content organic fertilizers i.e. F3, F5 and F7. We concluded that amending soil with organic fertilizers in combination with zeolite can be a beneficial approach for decreasing chemical fertilizer application rates and improving the sustainability of agricultural systems.

A field experiment was conducted during the winter (rabi) seasons of 2019–20 and 2020–21 at the Guru Kashi University, Talwandi Sabo, Bathinda (Punjab), to study the effect of irrigation schedules on different growth, yieldattributing characters, yield, quality and water use in Indian mustard [Brassica juncea (L.) Czern.] in relation to sowing time. Results revealed that, early-sown crop, i.e. 10 October, recorded the higher growth parameters, viz. plant height, dry-matter accumulation, primary branches/plants, secondary branches/plant, and yield-attributing characters, viz. siliquae/plant, seeds/siliqua, siliqua length and 1,000-seed weight of Indian mustard. The crop sown on 10 October gave the highest seed yield (1449 kg/ha) which was significantly higher than the crop sown on 25 October (1,171 kg/ha) and 10 November (643 kg/ha). Oil yield, nitrogen content and protein content were also significantly higher in 10 October sown crop. Early-sown crop, i.e. 10 October, resulted in the 21.2 and 119.5% higher water-use efficiency (7.55 kg/ha/mm) than 25 October (6.23 kg/ha mm) and 10 November (3.44 kg/ha/mm) sown crop. Application of 3 irrigations, viz. at branching, flowering and siliqua-formation stages, resulted in higher plant height, dry matter, primary and secondary branches/plant, siliquae/plant, 1,000-seed weight, stover yield and harvest index in Indian mustard. Three irrigations at branching, flowering and siliqua-formation stages resulted in significantly higher seed yield (1,658 kg/ha), oil content (42.2%), oil yield (699.7 kg) and protein content (22.3%). This treatment resulted in the 23.3% higher water-use efficiency (6.50 kg/ha/mm) than the control (5.27 kg/ha/mm).

To investigate the effect of mulch and different cultivation methods on the quantitative and qualitative yield of oil sunflower (Helianthus annuus L.) in Ahvaz climate, a factorial experiment in randomized complete blocks with three replications in the 2017-2018 crop year was in the research farm of Agricultural Sciences and Natural Resources University of Khuzestan. The first factor includes different types of mulch in five levels (non-application, wheat straw, white plastic, live mulch (mung bean cultivation), and black plastic) and the second factor includes three-level cultivation method (on a flat surface, ridge cultivation, and inside the furrow cultivation). The results showed that in the flat surface and on the ridge, black plastic produced the highest amount of chlorophyll a, b, and In the inside the furrow, the highest chlorophyll a was obtained in the application of living mulch. The highest grain yield and oil yield were obtained from the interaction of wheat straw mulch × in the furrow and wheat straw mulch on the ridge. In addition, the highest harvest index was obtained in the treatment of white plastic mulch on a flat surface with an average of 51.85%. In general, it can be said that the treatment of wheat straw and straw × in the inside the furrow and wheat straw × on the ridge were superior in terms of quantitative and qualitative performance.
