4. Achievements, Recommendations and Findings:

1993-2000

1. Survey of salt affected soils and quality of irrigation water:

Soil salinity and poor quality of irrigation water have been found to be two most important constraints affecting the optimum production of crops. For assessing type of salt affected soils and quality of irrigation water 819 representative soil samples and 181 irrigation water samples have been analysed, 66.1% soil samples were found to be salt affected which were classified into following categories:

Saline- 43.5%; Saline sodic- 9.8 % and Sodic soils- 12.8%. This study is useful in salt affected soils. Gypsum requirement was worked out for saline sodic and sodic soils.

80.2% irrigation water was of poor quality which were classified as follow:-

Saline- 49.2%; Saline Sodic- 26.7% and Sodic 4.3%. 8.3% of irrigation water had high RSC ( > 5 me/l) values.

Suitable technology for managing poor quality irrigation water is being worked out.

Soil Fertility: Judicious use of fertilizers based on soil testing is one of the most important factor governing productivity of soils. Analysis of 819 soil samples for available N,P and K revealed that 85.8% soils were low in available N whereas 14.2% medium in it. Available P was low in 19.0%, medium in 39.7%  and high in 41.3%. Available K₂O was high in 84.5% of the samples whereas 15.5% contained medium range.

Available Micronutrient:         117 representative soil samples were analyzed for DTPA extractable 10.2% samples were deficient (< 0.60 ppm) in available zinc, 38.4% marginal (0.60-1.20 ppm) and remaining 51.8% sufficient in it. Deficiency has been further confirmed by the soil test crop response studies with wheat as a test crop as reported in the section on nutrient management in saline soils.

2. Verification of most suitable varieties of crops for the zone IIIb.

S.No.	Crop	Varieties
(i)	Mustard	RH 819, BIO 902, RH 30, Pusa Bold, RN 393, Laxmi
(ii)	Wheat	Raj 1482,CPAN 3004, Raj 3765, Raj 3777, Lok 1
(iii)	Barley	RD 2503, RD 2552, RD 2035
(iv)	Gram	RSG 44, KPG 59, RSG 888, CSJD 884
(v)	Lentil	K 75, Sehore 74-7, L 4076
(vi)	Clusterbean	RGC 936, RGC 986, RGC 1003

3. For mustard crop grown under unirrigated heavy texture soils application of 40 Kg N and 40 Kg S ha^-1 (through gypsum) was found optimum.

4. For mustard crop 45 cm. spacing between row to row has been found optimum under tank bed, heavy texture soils.

5. The spray of Thio urea @ 0.1% at 60 DAS increases the seed yield of mustard by 10 to 12% over control. In this way an additional return of about Rs.3024 ha^-1 can be fetched.

6. The application of Zinc Sulphate @ 20 Kg ha^-1 significantly increases the grain yield of lentil.

7.  Mixed cropping of lentil + mustard (12:2 or 6:1 rows) was found superior over lentil alone or over farmers practice (seed mixture).

8. Research conducted to find out the response of sulphur under tank bed micro farming situation revealed that increasing levels of sulphur, significantly increased the grain yield of cluster bean upto 40 kg S/ ha^-1, beyond which no further response was observed.

9. Wheat (Raj 1482) irrigated with saline sodic water (EC : 10.4 dsm^-1 and SAR : 10.6 ) responded significantly to N, P and Zn. Combined application of 120, 60 and 40 Kg/ ha of N, P₂O₅ and ZnSO₄, respectively increase the grained yield of wheat by 14.0 % over control (90Kg N + 40Kg P₂O₅  ). It suggests that under saline conditions N, P and Zn requirement is higher as compared to non saline conditions.

10. The optimum seed rate for Gram semi bold varieties was found 80 Kg ha^-1 and for small seeded varieties was found 60 Kg ha^-1.

Highest lentil grain yield was recorded with the treatment 40 P₂O₅ ha^-1 through DAP+ PSB closely followed by 40 P₂O₅ ha^-1 through DAP +  PSF. Among the sources of phosphorus DAP found superior over Rock phosphate but there was no significant difference among them, whereas PSB, found superior over PSF. The increase in grain yield was 40.53%, 38.26% and 28.95% by 40 Kg. P₂O₅ ha^-1 through DAP, 40 Kg. P₂O₅ ha^-1 through DAP + PSF and 40 Kg. P₂O₅ ha^-1 through DAP over control. The combined effect of DAP with PSB at 40 P₂O₅ ha^-1 showed maximum positive effect.

The time of sowing in nursery to produce seed bulb for kharif onion significantly affected the onion yield in all the three consecutive years. The highest mean yield 104.66 q/ha was obtained at sowing of 15 jan., which were significantly higher than that of 15 Nov. & 15 Feb., however sowing at 15 Dec. proved at par with that at 15 Jan. Storage technique of seed bulb shows insignificant results.
