Tillage Methods

Conservation agriculture is a concept for resource-saving agricultural crop production system that serves to achieve acceptable profits and sustaining production while conserving the environment. The popularity of zucchini also known as baby marrow in the Kingdom of Eswatini has increased in recent years specifically for its economic value in the foreign market. This study was carried out at Malkerns Research Station, Malkerns in the Middleveld of the Kingdom of Eswatini to assess the effectiveness of different tillage methods and cultivars on growth, yield and quality of zucchini. The tillage methods used were zero, basin and mulch tillage. Furrow tillage was used as a control. The results showed that tillage methods had significant (P<0.05) differences in growth and yield of zucchini. Minimum tillage plants exhibited lowest number of leaves (9.5), vine length (36.4 cm), leaf area index (2.5) and number of flowers (6), number of fruits (1.3) and marketable yield/plant (4.6 ton/ha). Non-significant (P>0.05) differences were obtained from plants grown under basin, mulch and furrow tillage. The highest vine length (69.6cm), leaf number (17.0), LAI (3.6), and marketable yield (15.7 ton/ha) were obtained in zucchini plants grown under basin tillage system. However, there were no significant (P>0.05) differences in accumulation in leaves of zucchini plants of mineral content. In terms of the cultivars there were no significant (P>0.05) differences in vegetative growth. Star 8023 showed superiority in terms of number of fruits and marketable yield. It was observed that minimum tillage was less suitable in zucchini production as compared to other tillage systems. For higher production in zucchini, basin, furrow and mulch may be used. The best cultivar to use is star 8023.

Effect of Nitrogen Fertilization on Yield and Quality of EndiveThe aim of the experiments carried out in 2007-2008 was to assess the effect of various nitrogen doses on the growth, yield and nutritional value of two endive cultivars Cigal and Excel. The effects of two types of fertilizers were compared: that of ammonium nitrate with that of the product Entec-26. On the basis of the results obtained, it was shown that endive cv. Excel produced a marketable yield that was on average by 35.5% higher than that of the cultivar Cigal. A significantly higher marketable yield of endive was obtained by fertilizing with a single dose of the fertilizer Entec-26, particularly at the rates of 90 and 135 kg N·ha-1, and also 180 kg N·ha-1. The experiments also revealed a significant effect of the fertilization method and nitrogen application rate on the biological value of the endive cultivars under evaluation. The cultivar Excel was characterized by a higher degree of nitrate accumulation, whereas the cultivar Cigal had a higher vitamin C content, dry weight, and chlorophyll content.

A field experiment was carried out in district-Sangli (Maharashtra) to study the effect of sustainable agricultural practices for improving growth, yield and quality of turmeric (Curcuma longa L.) variety Salem during 2018 and 2019. Twelve treatments were evaluated in randomized block design with three replications. The results revealed that plant height, leaves/plant, width of leaves, leaf area index and clumps/plant tended to increase with age of plant and maximum values were recorded at 150 DAP, irrespective to various treatments. Application of 50% RDF + 50% NC resulted in significantly higher fresh weight of primary rhizome (46.5 g), fresh weight of secondary rhizome (55.5 g) and high marketable yield of rhizome (251.2 q ha-1) over control. The total yield of fresh rhizome per plot was comparatively on higher side (418.5g) when compared to control (308.1g) and other treatments. The application of 50% RDF + 50% NC proved superior for enhancing the quality parameters of turmeric such as fats (1.06 %), protein (1.25 %), carbohydrates (9.25 %) and curcumin (5.13 %) content to other treatments. Soil productivity was recorded maximum due to combined application of 50 % RDF + 50 % NC than the application of all these fertilizers alone. Fertility status of post-harvest soil improved with most of the treatments over control and higher values were recorded with 50% RDF + 50% NC treatment.

The aim of this work was evaluation of 24-epibrassinolide influence on yield and quality of head lettuce in optimal and reduced moisture conditions and work out recommendation of 24-brassinosteroids use for lettuce in growers praxis. Field trials were carried out on land belonging to the Demonstration and Research Station of CULS in Prague – Troja in 2009 and 2011. Planting on 27. 8. 2009 and 20. 8. 2011 was done at planting space 0.25 × 0.30 m, each variant in four repetition (single plot 4,5 m2). Seedlings of head lettuce (cultivar Santoro – Rijk Zwaan) were used. Irrigation was carried out by microspraying, and was based on current values of efficient water capacity (EWC); the critical value of the EWC was 80% for optimally irrigated fields (irrigation O), and 50% for variants with reduced levels of irrigation (irrigation S). The total amount of irrigation water during vegetation were as follows: the variant with optimal levels of irrigation (O) had 131 mm in 2009 and 123 mm in 2011; the variant with reduced levels of irrigation (S): 58 mm in 2009 and 63 mm in 2011 Three variants were in both (O and S) conditions: A – no application of 24-epibrassinolide, B – 1 × 24-epibrassinolide application immediately after planting, and C – application of 24-epibrassinolide 2 x (immediately after planting and then after 14 days after 1st application). Concentration of 24-epibrassinolide was 10−6. Following parameters of head lettuce were set after harvesting (10.–12. 10. 2009 and 14.–15. 10. 2011): weight of single heads, marketable heads, marketable yield (in pcs/ha and t/ha) and ascorbic acid and nitrate contents. Influence of 24-epibrassinolide on single lettuce head weight was not significant, decrease of head weight was evident after 24-epibrassinolide application in some variants. Significant increase of marketable heads number and their percentages were noted after 24-epibrassinolide application in optimal moisture conditions – in variant B of 12 261 heads/ha (11.1 %) and in variant C of 16 279 heads/ha (14.7 %) compared with non treated variant A. This trend was not visible in reduced moisture conditions. Increase (nonsignificant) of total marketable yield (in t/ha) was noted after 24-epibrassinolide application. No significant differences were founded among the ascorbic acid contents in each irrigation variant. A higher ascorbic acid content (by approximately 11.9 % in variant C compared with control A) is evident after application of 24-epibrassinolide in the variant with lower levels of irrigation – S. Contrarily, decrease ascorbic acid content is indicated in the optimal levels of irrigation – O (by approximately 16.8 % in variant C compared with control A). The influence of 24-epibrassinolide application on the nitrate content was not significant, but the trend of nitrates decrease in optimal irrigation conditions is evident.

A field experiment was conducted at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, Uttar Pradesh, to assess the effect of different nutrients and their integration on growth, yield and quality of Indian mustard (Brassica juncea L.). Indian mustard cultivar Pusa Mustard 31(PDZM -31) was grown during winter (rabi) season of 2020-21. The treatments comprised of Control (T1), 100% N (T2), 100% NP (T3), 100% NPK (T4), 125%NPK (T5), 100% NPK+ S@40kg ha-1 (T6), 100%NPK+ Zn @5kg ha-1 (T7), 100%NPK + B @1kg ha-1 (T8), 75% NPK+ Vermicompost @ 2t ha-1 (T9), 75%NPK+ Farm Yard Manure @ 6t ha-1 (T10), 75%NPK + VC @ 2t ha-1+ Azotobacter (T11) and 75% NPK + FYM @ 6t ha-1 + Azotobacter (T12). Results revealed that treatment T11 (75% NPK + VC@2t ha-1 + Azotobacter) and T12 (75% NPK + FYM@6t ha-1 + Azotobacter) exhibited significant influence on the growth, yield and quality of mustard as compared to the application of 100% NPK alone. Significant improvement in growth parameters viz. plant height, leaf area index, dry matter accumulation as well as crop growth rate, relative growth rate and yield was recorded with the application of T11 and T12. Maximum oil content (40.67%) was obtained in T6 (100% NPK+ S@ 40kg ha-1) and maximum oil yield (796.76 kg ha-1) was obtained in T12, it remained at par with T5, T6, T10 and T11. Maximum protein content (21.75%) was found in T12 which was on par with T5, T9, T10 & T12. The maximum protein yield (492.88 kg ha-1) was obtained in treatment T12 which was statistically on par with T11, T5 and T6 respectively. T11 and T12 exhibited significant influence on the growth and yield of mustard as compared to other treatments respectivity. Integration of inorganic and organic sources of nutrients improved the growth parameters, yield and quality parameters of Indian mustard, whereas the use of chemical fertilizer alone showed a pronounced decline of these parameters.

Greater attention should be paid for increasing the yield per unit area by growing modern varieties of rice through improved cultivation practices. An experiment was conducted for investigating the effect of variety and date of harvesting on yield performance of modern rice varieties during Kharif, 2012 at Agricultural Research Station, Bapatla. The experiment was laid out in a split-plot design with three replications. Main treatments comprised of four rice varieties namely, BPT 5204, BPT 2270, BPT 2231, NLR 34449, NLR 28523 and MTU 1010 and sub treatments comprised of three time of harvesting viz., 25, 30 and 35 days after flowering. Plant growth, yield attributes, yield and quality of rice varieties were significantly influenced by different dates of harvesting. BPT 2270 was found significantly superior to all other varieties in respect of effective tillers, grains panicle-1, grain yield, straw yield and hulling per cent, milling per cent and head rice recovery. Among three harvesting times, the highest grain yield (6250 kg ha-1) and straw yield (7314 kg ha-1) were obtained when the crop was harvested at 30 days after flowering. The interaction effect of variety and date of harvesting was significant in respect of grain and straw yield. The highest grain yield (7771 kg ha-1) was observed in BPT 2270 when harvested at 30 days after flowering. Therefore, optimum date of harvesting for higher grain yield may be 30 days after flowering for avoiding immature stage as well as shattering loss.
